Description

The conveying of granule materials and metering

The background 1 of invention, the field that the present invention relates to

The present invention relates to be used to carry and measure the equipment and the method for granule materials, in specific embodiment, the present invention relates to a kind of granule materials load transfer device that has improved, no matter this improved equipment can both be used for range of sizes widely conveying and the metering of solid material still overcoming under the situation of pressure under the conventional environment condition.2, the description of prior art

Many equipment be used to or carry or measure granule materials (such as, the mineral of coal, other exploitation, dried food, other is with the article of doing solid-state or that can particulate form carry, but be not limited in these materials).Such load transfer device has comprised belt conveyor, rotovalve, storage bin hopper, spiral feeder, or the like).Representative type measurement or metering outfit comprise belt scale, measure the metering device and the analogue of volume.In order to satisfy the requirement to carry and can measure granule materials, generally must use two kinds of equipment simultaneously, or these two kinds of equipment are combined in the system use.

Yet some applicant's the pumping unit of formerly applying for a patent has the ability of carrying and measuring granule materials concurrently.These formerly the design-calculated example be included in those rotating disk type pumps that will discuss in the following US Patent, wherein each part has all been transferred the possession of or authorization is given cessionary of the present invention.Listed each part wherein for your guidance at this: US Patent 4,516,674 (promulgation day is May 14 in 1985); US Patent 4,988,239 (promulgation day is January 29 in 1991); And US Patent 5,051,041 (promulgation day is September 24 in 1991).Though wherein some formerly the design-calculated pump demonstrated and overcome lower pressure head and some abilities of the defeated granule materials of pump, yet these pumps do not have and overcome very high gas or fluid head and the defeated ability of pump.

The inventor finds, by a pumping system mobile granular solids may be subjected to intrasystem various power (such as, do not wish component, friction force or the gravity of the propulsive effort that produces) on the diverse location and the effect on the different directions.The proper flow that these power can make granular solids certain zone of pump or certain position around its inlet stoped or even stop under.This just may make these particles finally across going into interruption-forming bridge joint (bridge), and the grain flow by inlet is stopped.In order to illustrate this phenomenon, Fig. 1 has shown a rotating disk type solid pump 10, and it has a casing (not shown), 12 and outlets 14 of an inlet.Transfer passage 16 extends in inlet 12 and exports between 14.(one is in the drawings with 17 expressions at two rotating discs for this transfer passage, another is not shown in the diagram) the relative face of two cardinal principles between form, can and export casing between 14 with respect to inlet 12, and have at least an arcwall to extend in inlet 12 and export between 14 towards outlet 14 motions.

Pump 10 can pass to 20 1 tangential forces of granular solids or a thrust 18 along the hand of rotation 22 of dish 17.At inlet 12 places, this tangential thrust 18 can be pushed granular solids to fixation wall 24.As a result, can be in " dead band " 28 at the granular solids 20 at fixation wall 24 places, or, form a motion solid group slow or that stop at inlet 12 or at its contiguous place.

Dead band 28 can reduce the flow velocity that streams enter pump (and, therefore also reduced the defeated rate of pump).Accumulation and/or the avalanche of cluster of grains in the dead band can make the flow velocity of the material by pump produce fluctuation, thereby also the measuring accuracy of this system produced deleterious effect.In system, overcome the pressure of gas or fluid and pump is defeated, perhaps overcome the pressure head that caused by particle and pump is defeated, for keeping a pump intake that does not stop, thereby so that pump is full of the effect of playing pressure barrier by granule materials all the time is very important.

And for some granule materials, 28 delay can cause more problem to particle in the dead band.For example, when carrying food by pump 10, food can be detained considerable time dead band 28 in, just may make the food spoilage damage and causes serious health problem.Another example is that the material with higher levels of humidity of some type can become broken and viscous when it is trapped in the dead band 28 after the long period, thereby more be difficult to carry.Therefore, providing a kind of its inlet to be designed to reduce to greatest extent or avoid the formation in dead band 28, thereby can not make particle slack-off or stagnate in the dead band, be used to drive or the equipment of the defeated granular solids of pump, will be desirable.

The ability that granule materials to given type that equipment had applies propulsive effort depends on the many factors relevant with configuration with this design of plant.The design of some existing installation and configuration make them be not suitable for requiring bigger propulsive effort and/or requiring propulsive effort that granule materials is used under the efficient situation of carrying at some.For example, in a certain use, may must overcome resistance and the delivery of particulate material material, for example overcome gravity and carry vertically upward, or upwards carry, or overcome a pressure head and/or cross long distance and carry along the inclined-plane.Therefore, providing a kind of the improvement that granule materials is applied the ability of propulsive effort and can be used for carrying and the measures range equipment and the method for granule materials widely, will be desirable.

Wish to overcome pressure and carry and the example that measures granule materials is a lot (for example, the gas of the outlet side of delivery system and/or hydraulic pressure are greater than the pressure of this system entry side).Provide a kind of under the conventional environment pressure condition, or overcome owing to entering under the pressure head condition that pressure charging system causes (herein, the air pressure of equipment outlet side environment and/or hydraulic pressure are greater than the pressure of this equipment entrance side), the equipment of the defeated and metering ability of pump is all arranged, will be desirable.

Be used to carry or when measuring the high efficiency equipment of granule materials, have many factors to consider in that design is a kind of.The quantity of the granule materials that for example, is transferred, size and type all must take in.In course of conveying, material is transferred the degree that the distance that surpasses and ambient pressure change and also must takes in.Therefore, provide a kind of can be under the conventional environment condition, also can under the supercharging condition, be used to carry and measure the kind pumping unit of granule materials widely, will be desirable.

Carry on a large scale and/or measure granule materials and exist special problem.A kind of equipment or system of carrying certain class granule materials of being applicable to may not be suitable for the inhomogeneous material of conveying.For example, colliery, Kentucky (Kentucky) still intactly has by such as spiral feeder and the such load transfer device of load-transfer device.But the colliery of Western United States can make coal become broken and reduces its quality greatly in common conveying running.Therefore, be desirable to provide a kind of can be under the conventional environment condition, can be also under the supercharging condition, carry various types of coals (or other friable material) but do not reduce the equipment of its quality as far as possible.

When any delivery system of design, the aqueous ingredients of granular solids is another factor that must take in.Many equipment that are suitable for carrying the particle of all dry may just lose efficacy when the humidity of granule materials increases.For the particle metering outfit, situation also is identical.Be designed to measure the common metering outfit of dried particles, may and be not suitable for measuring moist solid.Therefore, provide a kind of can be under the conventional environment condition, also can be under the supercharging condition, carry and/or metering granular solids and needn't consider the load transfer device of its humidity, will be desirable.

Can find out significantly from the above-mentioned background technology, be used to transmit or the treatment facility of the defeated solid of pump or the demand that the pump transfer device has reality for a kind of like this.Granule materials be carried and be measured to this equipment can simultaneously as single unit running under conventional environment conditioned disjunction supercharging condition.Kind particle widely can both be carried and measure to this unit under condition widely.In addition, it is firm, mechanical simple and durable that this unit should be constructed, so that it can turn round and trouble free in for a long time continuously.

General introduction of the present invention

A kind of streams efficient and stability that can improve inlet can be improved propulsive effort and/or overcome gas or the equipment and the method for the conveying of fluid head and metering granule materials, conforms to embodiments of the invention.These solid pumps that conform to the embodiment of the invention are specially adapted to carry far-ranging granule materials, comprise compound big and little particle, particle, and the particle of different humidity.

According to embodiments of the invention, granule materials enters with at least one and drives in the adjacent delivery duct of wall, this delivery duct then better between two driving walls (for example, the wall that faces one another of two parallel, relative dishes, but be not limited thereto kind of a situation).One (or a plurality of) drive wall and move towards an outlet from an inlet, and the particle of granule materials is connected mutually, and outermost particle drives the wall engagement with being somebody's turn to do (or a plurality of), so that propulsive effort is passed to particle from these (or a plurality of) driving wall.According to various embodiment of the present invention, the inlet of this delivery duct is modified, so that reduce to greatest extent or avoid these (or a plurality of) to drive wall the situation that particle pushes the dead band is taken place.In the dead band, the sport of particle is slowed down or is stopped.

According to one embodiment of the present of invention, the improved inlet of this that is provided have with two driving walls in each adjacent shield.Each shield is adjacent with the corresponding driving wall, so that an obstacle is provided, thereby stops the granule materials that is positioned at driving wall place to contact with the driving wall.Otherwise, drive wall and can push the particle that is in contact with it to dead band.In a further embodiment, what the improved inlet that is provided had a moulding connects boundary's wall, to reduce to greatest extent or to avoid forming the dead band.In another embodiment, the improved inlet that is provided has a fixation wall, and boundary's wall is relative with connecing, and it is shaped to certain shape to reduce to greatest extent or to avoid forming the dead band.In an embodiment who also has, the improvement that provided inlet has a particle propelling unit (such as a drives impeller device, drive roller arrangement, vibrator, fluid propeller arrangement or allied equipment), to pass to additional positive force of particle (direction is towards the driving pipeline of this equipment), form the dead band otherwise in this zone, understand.Further embodiment used some or all in the foregoing description comprehensively so that a kind of improved inlet to be provided.

In preferred embodiment, granule materials is fully jam-pack or compacting of quilt in delivery duct, so that formed by being across synthetic unsettled solid or the bridge joint of the groups of grains delivery duct width, that connect mutually substantially.When the granule materials when afterwards entered this inlet, the accumulation real estate had been given birth to stable bridge joint in delivery duct.For some granule materials, may not use choked flow lock (chokes) or the power shaft turning gear (dynamic relative disk motion) of being correlated with, also can produce the bridge joint of accumulation.But further embodiment can comprise choked flow lock or the relevant shaft turning gear of power.US Patent 5,051,041, US Patent 4,988,239 and U.S. Patent application 07/929,880 examples of all having described these choked flow locks and shaft turning gear (wherein each part has all been transferred the possession of or authorization is given the cessionary of the present patent application, has listed wherein each part for your guidance at this).

In various embodiments, particle connects mutually the unstable solid that is constituted and has formed the obstacle that overcomes pressure head, reflux to stop pressure by this pump, this backflow from this outlet side towards inlet side.Therefore, embodiments of the invention relate to a kind of delivery duct type granular solids pumping system, and it has and overcomes gas or fluid head and the defeated improvement ability of pump.

Because the effort of extensive studies and exploitation concentrates on (running in this case in the running under higher gas or the fluid pressure condition, the air pressure of delivery side of pump side or fluid pressure are greater than the pressure of the entrance side of pump), as a result, the present inventor has had recognized that many factors help improving the force lift Movement Capabilities.This has just caused series of development, as what described at this, can have influence on any one or its combination in these factors by this, overcomes gas or fluid head and the defeated ability of pump thereby improved the granule materials pumping system.

For example, drive surfaces to the ability of moving particle transmission of drive force, suppress the ability that the section of the contiguous drive surfaces of delivery duct is pressurized and the structure and the length of this pipeline, above-mentioned every all being found overcomes gas or fluid head with equipment and ability that pump is failed is relevant.Therefore, many embodiment of the present invention provide the approach that improves the particle transmission of drive force.The present invention further embodiment provide the approach that prevents the delivery duct supercharging, and other embodiment provide the size and the structure of equipment, to improve the operation under the pressure condition.

According to an embodiment who improves the propulsive effort transmission, the drive surfaces of motion (or a plurality of surface) has at least one sudden change place, and this sudden change place has a drive surfaces for the downstream.This sudden change place defines one and carry to promote the district, and it has improved the concatenation ability between the particle of bonded assembly of drive surfaces and unstable solid.In other embodiments, many sudden changes place, for example sudden change place of many well-distributeds is provided on the drive surfaces.

Improved the connection of unstable solid by means of drive surfaces, again then improved the ability of unstable particulate matter bridge joint.The bridging capability that has improved with the particle of bridge joint, causes the formation of a pressure barrier of having improved.

According to further embodiment of the present invention, the shape and the size of outlet conduit are designed to, can remain on a moving cluster of grains wherein in the defeated process of pump, like this, this moving cluster of grains plays a part to overcome the gas of equipment outlet side or the dynamic tamper of fluid pressure.Used the pressure relief opening device in further embodiments, by means of it, pressure can or drive the passage from outlet conduit and release.

Equipment and method according to the embodiment of the invention provide all even constant flow velocity, so be particularly suitable under various conditions, have not only carried but also measured granule materials.By the rotative speed of measuring disk, and set up relational expression between the cross-sectional area of this rotative speed and this pipeline, the volume of the granule materials of being sent to can be by convenient and measure exactly.In the metrological operation process, monitoring equipment can be included easily, to be sure of being full of solid in the path in metering process.

Detailed description to preferred embodiment of the present invention

To be described in detail the present enforcement of considering best way of the present invention below.This description does not have limiting meaning, and is purpose with the rule that illustrates enforcement of the present invention only.Scope of the present invention will be given best limiting by appended claim.

According to preferred embodiment of the present invention, be used to carry with equipment that measures granule materials and method the propulsive effort that has been endowed the improvement relevant with stability, improved (for example, overcome resistance and pump is defeated) with the efficient that improved and stability with inlet streams efficient and/or improved overcome gas or fluid head and the defeated ability of pump.The inventor has recognized that many factors help improving the defeated efficient of pump, help the raising (at this, the air pressure of delivery side of pump side or fluid pressure are greater than the pressure of the entrance side of pump) of the pump Movement Capabilities under pressurized environment.This has just caused development, as what described at this, mat can have influence on any one or its combination in these factors, just can improve the granule materials pumping system to overcome gas or fluid pressure head and the defeated ability of pump, or improve this pumping system and make it the more effectively pump Movement Capabilities under conventional environment or subnormal ambient.The embodiment of the invention can be used under ambient pressure conditions, also is used in to carry far-ranging granule materials under the supercharging condition, comprises compound big and little particle, particle, and the particle of different humidity.

With regard to the type structure of rotating disc, will discuss various embodiment of the present invention below.At this, a pair of relative wall that separate, parallel, rotating disc has formed the driving wall, and a driving pipeline or passage are arranged between two driving walls.But, recognize that other embodiment of the present invention can be used or be provided to the driving wall of other structure rather than rotating disc formation, for example, common with linear mode movable wall motion, spaced-apart, and this wall has been determined a delivery duct or a passage between movable wall.

With label 30 demonstrations among Fig. 2 is the equipment according to the embodiment of the invention.This equipment 30 comprises that a casing (not shown), one drive rotor or

rotary disk assembly

31,32 and outlets 34 of inlet.Delivery duct or passage 36 extend in inlet 32 and export between 34.Rotary disk assembly 31 has two relative rotating discs 37 (having omitted one of them among the figure, to demonstrate the inner structure of this equipment).Dish assembly 31 can be connected in any suitable drive system.For example (be not limited to) to be connected to (not shown) on hydraulic engine or the electric motor, press the rotation of direction shown in the arrow 33 so that coil 37.

Between the apparent surface of two rotating discs 37, formed delivery duct 36.As shown in Figure 2, delivery duct 36 is extended at

inlet

32 and 35 of at least one arcwalls exporting between 34 and further limits.More preferably, arcwall 35 is motionless with respect to casing or even forms the part of casing.When 37 whens rotation of dish, the surface of dish provides driving wall or the drive surfaces along transfer passage, and with respect to casing with from 32 the direction motions that enter the mouth towards outlet 34.As mentioned above, in other embodiments, can use two facing surfaces of for example moving wall of other type different to form the driving wall with rotating disc.

With reference to figure 2, delivery duct 36 has one first subregion 38 between two rotating discs 37, is lower than inlet 32.At inlet 32 places, granular solids 40 is admitted to, and 32 is conducted to delivery duct 36 by entering the mouth.As above-mentioned discussion to Fig. 1; for these improved prior aries set forth herein; some enters the particle of first subregion 38 of delivery duct 36, can be pushed into or be pressed into a dead band, and a microinching or the particle that does not move can accumulate in the dead band.But the improvement inlet that embodiments of the invention provide can reduce or avoid a such particle to produce in the dead band to greatest extent.

Fig. 2 and Fig. 3 have shown an embodiment, and shield assembly 42 is installed in first subregion, 38 places between two rotating discs 37.Shield assembly 42 is made of two flat part between two rotating discs, and each flat board covers on the corresponding dish 37 section adjacent with first subregion 38 of transfer passage 36.As a result, be imported into the granular solids (between two flat part of shield assembly 42) of first subregion 38, blocked substantially by the shield assembly and do not contact with the drive surfaces of rotating disc 37 in subregion 38.

Therefore, owing to there is shield assembly 42, just make the drive surfaces of dish can pass to tangential thrust or pressure on the particle 40 that is in first subregion 38 originally, no longer be applied on the particle.In this respect, shield assembly 42 utilizes its shape and position, can dwindle even eliminate can make originally to be positioned at the tangential thrust of rotating disc 37 granular solids 40 on every side to fixation wall 43 motions of inlet 32.As a result, granular solids 40 inlet 32 between the plate of shield assembly 42 of flowing through smoothly.

Notice that the granular solids 40 by 42 motions of shield assembly are come in the different radial positions of rotating disc 37, with angles different for hand of rotation, along the bottom 44 of shield assembly 42, contacts with the surface of rotating disc 37.Find that the bottom 44 of shield assembly 42 and the spacing h between the wheel hub 46 are to influential by the flow uniformity and the consistency of the inlet 32 and the granular solids 40 of delivery duct 36.In addition, shield assembly 42 is with respect to the position of transfer passage 36 and cover the shape of the shield assembly 42 on rotating disc 37 surfaces, and it is influential all particle to be left the radial position (relevant with dish) of shield assembly.Preferably, select the position of spacing h and shield assembly 42 and shape can obtain best flowing.The selection of these parameters depends on that the type of the material that will be transferred and this carry present environmental conditions.

In Fig. 2, shield assembly 42 is fixed on the bottom of inlet 32.In the embodiment that substitutes, this shield assembly and this inlet can form as a whole.Perhaps, this shield assembly can be fixed on the framing member rather than on this inlet.In one embodiment, the shield assembly links together with the material feeding bucket that is used to store granular solids, and the material feeding bucket is to be used for granular solids is supplied to the inlet of equipment.In further embodiments, a hopper can have an oscillatory system, so that the granular solids that comes out from hopper is admitted to easily.In these embodiments, the shield assembly can link together with oscillatory system, flows easily further to make granular solids.

What show with label 50 among Fig. 4 is equipment in accordance with another embodiment of the present invention.Equipment 50 comprises a casing 52, an inlet duct 54 and an outlet conduit 56.A driving disk assembly 58 rotatably is contained on the transmission shaft 60 in casing 52, and can be around the axle center rotation of transmission shaft 60.Any suitable drive element for example, but is not limited to, and hydrodynamic(al) or genemotor (not shown) can be connected to (for example, by transmission shaft 60) on the driving disk assembly 58, drives this assembly with the direction rotation of pressing arrow 64 among Fig. 4.

As what clearly illustrate among Fig. 5, driving rotor or dish assembly 58 comprise a pair of rotating

disc

66 and 68, and this all has internal diameter 70 and external diameter 72 to rotating disc.This driving disk assembly 58 also comprises a wheel hub 74.Even more preferably, two dishes of this driving disk assembly are detouchables, so that can enter into the inside of pumping unit, and make and safeguard or to change the parts of this equipment easier.

Rotating disc

66 and 68 comprises two interior surface opposing 76 and 78.Interior surface opposing can be the plane, also can comprise many sudden changes place 89 as described below.At these surface discontinuity places that drive on the wall transmission that is applied to the propulsive effort on the granule materials is improved, overcomes pressure head and carry out the defeated ability of pump and further be improved thereby make.

More preferably embodiment equipment 50 comprises one or more as binding round outside with the several metals shown in label 90 and 92 among Fig. 4.In other embodiments, a simple fixation wall, as above-mentioned Fig. 2 mesospore 35 was discussed, can be used to substituent as complicated outer hoop.

Outer hoop 90 and 92 is designed to make the delivery duct that forms between

card

76 and 78 to be sealed.Outer hoop 90 and 92 comprises a fixing inwall 94 and 96 respectively.Inwall 94 and 96 is combined with wheel hub 74 and interior surface opposing 76 and 78, defines delivery duct 100, like this, and the border of the cross-sectional plane of this pipeline on any set point that also just define length, exports from entering the mouth to along delivery duct.

With suitable analog bracket or set pin outer hoop 90 and 92 is installed on the casing.More preferably, inwall (or outside complexity under the situation of hoop for a plurality of inwalls) is accurately formed, and matches with the ring-shaped edge of rotating

disc

66 and 68 making it.In a preferred embodiment, the inwall of outer hoop extends axially (outer bind round horizontal) and correspondingly surmounts the

inside face

76 and 78 that drives rotor 58, to cover in the

inside face

76 and 78 that drives rotor.In acceptable accuracy (depend on, for example, the type of the material that be transferred and grain size), outer hoop is placed on external diameter 72 places near inside

face

76 and 78 as far as possible.In Fig. 4, but this outer hoop be not radiai adjustment shift near or away from the wheel hub 74 that drives rotor 58, thereby can not change the cross-sectional area of main transfer passage 100.

In an alternate embodiment, the size and dimension of outer hoop is confirmed as being fitted between two interior surface opposing 76 and 78, so that be that main transfer passage 100 forms an arc outer wall.In the figure, radial position that should outer hoop can by towards or regulated away from the mode of the wheel hub 74 that drives rotor 58, so that can change the cross-sectional area of main transfer passage 100, and the general profile of this pipeline can be chosen as expansion shape, contraction shape or iso-cross-section shape.For this purpose, can be a screw regulator, for example US Patent 4,989, and the screw regulator of the type shown in 239 is connected with one or more outer hoops.Inwardly or outwards adjusting is outer binds round, and can make outer hoop play the effect of obstruction or compacting when granular solids moves through pump, perhaps, can make pipe be expansion shape or have a unmodified cross-sectional area along pipeline.

In another embodiment of the present invention, the cross-sectional area contraction of pipeline 100 or expansion, and/or to the compacting of granular solids, be that nationality helps rotating disc 66 is placed on respect to realizing on rotating disc 68 position at an angle, so that the distance between adjacent with inlet duct 54 two opposite

inner face

76 and 78 just is different from inlet 54 and exports distance between these two opposite

inner face

76 and 78 of 56.In further embodiments, the relative angle between these two rotating discs can be regulated.The variation of this angle can make the change rate of the cross-sectional area between the entrance and exit change, thereby degree of shrinkage or obstruction or divergences different in the pipeline is provided.The embodiment of the dish of many angulations and for finishing the preferred construction of same purpose has been illustrated (this patent has transferred cessionary of the present invention, and quotes at this for your guidance) very fully in U.S. Patent application 07/929,880.

Equipment 50 also comprises a shield assembly 102, is contained between

rotating disc

66 and 68 and inlet 54 adjacents.Show that as clear in Fig. 5 shield assembly 102 is made up of pair of plates part 104, flat part 104 covers in the drive surfaces of two

rotating discs

66 and 68 neighboring entries 54.Each flat part 104 is arranged to dish 66 or 68 is adjacent accordingly, and stops with base 106 in an initial feed zone 108 of main delivery pipe or path 10 0.Initial feed zone can be limited at inlet 54 and wheel hub 74 usually towards between the section that enters the mouth, and between two

rotating discs

66 and 68.

As top shield assembly 42 was discussed, shield assembly 102 also is used for fully preventing when granular solids 91 is imported into initial feed zone 108 contacting with 68 surperficial position with rotating disc 66.Therefore, shield assembly 102 has reduced or eliminated such tangential thrust to greatest extent, the granular solids 91 that is this tangential thrust edge that can make contiguous

rotating disc

66 and 68 in other cases moves towards the obstruction sidewall 110 of inlet 54, thereby forms a motion cluster of grains slow or that do not move (dead band).

Because pass through the granular solids 91 that shield assembly 102 moves, with respect in

dish

66 and 68 the different radial positions, with different angles with respect to hand of rotation, bottom 106 along shield assembly 102, come in contact with the surface of rotating disc, for reaching the purpose that at the uniform velocity consistent granular solids flows, can be by selecting the shape of shield assembly 102, comprise the base 106 of selecting the shield assembly with respect to the angle of coiling sense of motion, and be further improved.The shape on base 106 and angle, determined along rotating disc which radially, particle can be along the base 106 withdraws from the shield assembly and flows out.

The range of sizes that drives rotor 58 can be very wide, and it depends on the type and the volume of the material that will be transferred and measure.More typically, rotating

disc

66 and 68 external diameter scope can be from several inches to several feet.The small rotation dish is suitable for carrying relative less solid material with metered volume most, for example food additives and medicine.Large-sized dish can be used to carry and measure a large amount of organic or inorganic solid materials, comprises food material, coal, gravel and similar material.This equipment reasonably well is applicable to carries and measures big and little particle and composition thereof, and can be used to carry and measure granule materials wet and that do.

Label 130 has been represented equipment in accordance with another embodiment of the present invention among Fig. 6.Equipment 130 comprises a polystyle inlet duct assembly 132, and this assembly 132 also defines a shield assemblies, and assembly 132 is between a pair of rotating disc of pressing arrow 135 directions rotations.Assembly 132 can be used for sending into a kind of granule materials, also can send into several dissimilar granule materials (adding a kind of different material in each post), makes it to enter simultaneously the delivery duct or the passage of pump.

In order to improve its ability to provide granular solids stream average rate, consistent by equipment 130, multiple entry pipeline assembly 132 has comprised that multiple entry conductor string 132a is to 132d, each conductor string all has wall (its function is as the top shield of having discussed), and is adjacent with the section of rotating disc 134.Conductor string 132a stops in the different radial positions of rotating disc 134 to 132d.In one embodiment of the invention, entry conductor post 132a is positioned at and stops up side 136 and stop at the edge adjacent with rotating disc 134, and entry conductor post 132d is positioned at and connects boundary's side and stopping with wheel hub 140 adjacents.132a compares with the entry conductor post, and entry conductor post 132b extends between two rotating discs 134 more deeply, and entry conductor post 132c extends deeplyer than entry conductor post 132b, but more shallow than entry conductor post 132d.The shape of entry conductor assembly 132 comprises the length and the cross sectional dimensions of each pipeline, can be selected so that each conductor string can provide desirable flow velocity.

According to the equipment of another embodiment of the present invention, in Fig. 7, represent with label 150.Equipment 150 comprises 152, outlets 153 of an inlet and a pair of rotating disc 154 of pressing the rotation of direction shown in the arrow 155.For fear of forming the dead band at inlet 152 adjacents, embodiment shown in Figure 7 has comprised a propelling unit or driving tool so that further pressure propelling thrust (direction is towards the delivery duct or the passage of this equipment) to be provided, and is applied to anyly may begin to accumulate otherwise can become on the particle in dead band.In the embodiment shown in fig. 7, be made of an impeller unit 156 in order to the device that propelling thrust is provided, impeller 156 can drive by any suitable device of mat, for example the electrical motor (not shown).

Between the pump on-stream period, towards the granular solids that stops up side 158 motions, be pushed in the main transfer passage 160 by impeller owing to the effect of the tangential thrust of coiling.Even more preferably, the rotating speed of impeller 156 is adjusted to and makes granular solids stream at the uniform velocity, consistent by inlet 152 and main transfer passage 160.Should be understood that Fig. 7 embodiment has shown the example of an impeller unit with applied thrust, and other embodiment can use with one of lower device or its combination, for example drive rotor, vibrator, pneumatics, gas or fluid pressurized machine, or other analogue.

According to the equipment of another embodiment of the present invention, in Fig. 8, represent with label 170.Equipment 170 comprises an inlet 172 and a pair of rotating disc 174 of pressing the rotation of direction shown in the arrow 175.Inlet 172 has such shape of cross section, and it is designed to reduce to greatest extent or avoids producing the dead band on every side at inlet 172 or its, to provide granular solids stream at the uniform velocity, consistent by inlet and equipment 170.In one embodiment, inlet 172 is W1 at the width of outside diameter (or stopping up side), and this width significantly connects the width W 2 of boundary's side 178 greater than it.Optimization is, width W 1 is towards width W 2 stenosis gradually, and W2 is about 1/3rd of W1.Select but other suitable relative dimensions can be by the type of the material that will be transferred, transport residing condition.

Graphic entrance shape defines at the flow velocity that connects boundary's side 178 place's granular solids, and it is significantly less than the flow velocity that stops up side 176 places (because inlet 17 2 at the cross-sectional area that connects boundary's side significantly less than the area that stops up side).As a result, enter and have only the particle of low percentum to be subjected to tangential thrust in the total number of particles of inlet, this tangential force can make the dead band form in other cases.So the possibility that forms the dead band has reduced.

Also have the equipment of an embodiment according to the present invention, in Fig. 9 with label 190 expressions.Equipment 190 comprises 192, outlets 198 of an inlet and a pair of rotating disc 194 with the rotation of direction shown in the arrow 196.Main delivery pipe 200 is limited between the rotating disc 194, and at inlet 192 and export between 198.In this preferred embodiment, inlet 192 has a lower region 202 to connect main transfer passage 200, also has a upper zone 204, and it and lower region 202 link together at the upstream side of granular solids stream.Lower region 202 have a sidewall (or stop up sidewall) 206 at outside diameter and with stop up sidewall 206 one of upstream relative and that be positioned at the obstruction sidewall and connect boundary's sidewall 208.Find,, can make granule materials be collected into liability in the dead band and obviously reduce or disappear by means of making in wall 206 or 208 one or two form significant arc or spill in outward flange diameter intersection with disk.

In one embodiment, connect boundary's sidewall 208 be spill and protrude towards the direction opposite with disc spins direction 196.In other preferred embodiments, stop up sidewall 206 shapes at an angle to limit an inlet of expansion gradually, so that, with the same direction of the stream of the granular solids in main delivery pipe, be imported into substantially in the entrance that enters main transfer passage by the granular solids stream of inlet 210.Find that the shape of more than discussing that connects boundary's sidewall and obstruction sidewall has reduced the influence of tangential thrust, this tangential thrust may have influence in other cases at inlet 210 or neighboring entry 210 places and produce the dead band.

With reference to figure 4 and Fig. 5, when the defeated solid of pump is in pressure charging system, wish that during pump is defeated whole cross-sectional planes of at least some sections of transfer passage 100 and outlet 56 all are full of by solid.This has just formed a barrier at delivery side of pump, and it is that an energy barrier air, liquid or solid stream return in the pump by outlet, thereby may produce the obstacle of deleterious effect.The bridge joint of particle accumulation provides the footing of the cascade that forms in proper order, and it makes is strengthened near the intensity of the particle bridge section that exports, and tolerates the elevated pressures of equipment outlet side better with activation.The embodiment of the invention is improved the streams by the inlet of pump, therefore, for remain on transfer passage 100 and outlet 56 be full of solid provide improved may, thereby also for overcome the pressure head pump defeated provide improved may.

In addition, find that drive surfaces passes to the ability of mobile cluster of grains to propulsive effort, equipment is overcome pressure head and the defeated ability of pump is influential.According to an embodiment who improves the propulsive effort transmission, the drive surfaces of motion (or a plurality of surface) has sudden change place that at least one has drive surfaces for the downstream.And the configuration at the one or more waveforms places (or sudden change place) on the dish apparent surface can change in different embodiment.Preferably, each sudden change place defines a transmission and promotes the district, this promotion district improved drive surfaces with interconnecting of unstable solid the concatenation ability of particle.In further embodiments, many sudden changes place are arranged on drive surfaces, all if any many equally spaced sudden changes place.

For example, on the opposite

inner face

76 and 78 of the rotating disc shown in Fig. 5 66 and 68, has sudden change place 89 equidistantly many and that radially extend.Preferably, sudden change place of interior surface opposing defines a symmetric channel that is used to carry particle, as clear demonstration the in Figure 10.In compacting and conveying particle process, this symmetrical configuration has alleviated the out of balance load on the bearing assembly (not shown) of support drive rotor.Each sudden change place 89 defines one and carry to promote district 254, and this conveyings promotes to distinguish 254 and has drive surfaces 256, a bottom surface 258 and the drive surfaces 260 (as shown in figure 10) towards the upstream for the downstream.

With reference to figure 5 and Figure 10, outer drive surfaces 256 for the downstream is perpendicular to

inside face

76 and 78, and it is crooked backward, so that when rotating disc 66 (and coil 68) when between entrance and exit, moving, compare with front end 262, exit (for example, the outlet among Fig. 4 56) is left in the tail end extension of this drive surfaces for the downstream.This recurvate configuration makes particle be easy to discharge in the exit.

In a preferred embodiment of Fig. 5 and Figure 10 demonstration, when carrying promotion district 254 to extend from the outside path position of inner diameter location on dish 66 (with coiling 68), conveying promotes the width increase in district 254.Being inclined upwardly towards the drive surfaces 260 of upstream of each rotating disc by the inside face of bottom surface 258 to this rotating disc.

According to the present invention, the configuration of sudden change place on interior surface opposing 76 and 78 can alter a great deal.In the preferred embodiment of Figure 10 and a rotating disc shown in Figure 11, sudden change place on interior surface opposing 76 and 78 comprised many equally spaced, radially extend and the section 282 of protuberance upwards, each such section has a surface 284 for the downstream, and the drive surfaces 286 towards the upstream that is positioned at the party upstream of this drive surfaces 284 for the downstream, wherein each is all substantially perpendicular to the inside face of this rotating disc.Upwards the section 282 of protuberance also comprises an inside face 288 and an outside face 290, and they all are extended to a surface 284 and the surface 286 towards the upstream for the downstream, and all substantially perpendicular to the inside face of this rotating disc.

This inside face 288 is set at foreign side's one side of the internal diameter 292 of rotating disc, substantially perpendicular to the radial component that runs through herein.This outside face 290 is set at interior side one side of rotating disc external diameter 294, and substantially perpendicular to the radial component that runs through herein.Upwards the section 282 of protuberance also comprises a top surface 296, and it is parallel substantially with the inside face of rotating disc.The width of each top surface 296 is expanded along with this top surface 296 extends near its external diameter 294 places from the internal diameter 292 near this rotating disc, so that, then keep constant when extending near internal diameter 292 near external diameter 294 places at this recessed portion 298 by the adjacent width that upwards swells the recessed portion 298 that section 282 defines.Upwards bump 282 is recurvate, so that when rotating disc moves between entrance and exit, compares with inside face 288, and this outside face extension is to away from the exit.

On the other hand, interior surface opposing can comprise the waveform place of radial expansion, and it is defined as: a series of protrusion place and pits that replace of similar wave.Other embodiment then use simple oncus or groove in the disk wall.

Improvement between unstable solid and drive surfaces (for example, this drive surface has groove or other sudden change place) be connected to each other, form the solid of shakiness and the ability of bridge joint then also improved particle.Particularly, the granuloplastic unsettled solid group that has interlinked interlinks with the surface discontinuity place that drives wall, as shown in figure 10, and the improvement that the result causes propulsive effort to transmit, thereby, also caused the improvement of particle bridging capability.

In many above-mentioned preferred embodiments, the propulsive effort that drives rotor (31 or 58) has increased owing to be provided with sudden change place on interior surface opposing 76 and 78.The propulsive effort of equipment can be defined as the pump Movement Capabilities of equipment, and just the equipment predetermined resistance that overcomes predetermined grain-to-grain pressure or any kind of orders about granular solids does not cause the slippage on interior surface opposing 76 and 78 of this granular solids by its main transfer passage ability.Such as gravity, be connected to the pressure charging system in the equipment outlet supercharging fluid (gas or liquid) or the two combination, all may cause resistance.

Used one or more to improve the combination of features of defeated power of equipment pump or propulsive effort among some other embodiment.For example, fixedly inwall 94 and 96 of each outer hoop 90 and 92 (Fig. 5), available low-friction material, for example coating of the material of polytetrafluoroethylene or other super high molecular weight so that granular solids and fixedly inwall 94 and 96 s' friction reduce.And the result that friction reduces is that propulsive effort has increased.In another embodiment of the present invention, can from material, select, to improve propulsive effort with great friction coefficient in order to the inside face 76 of making

rotating disc

66 and 68 and 78 material.In further embodiments, the smooth degree or the roughness on surface also depended in the friction between drive surfaces 76,78 and the granule materials.Like this, propulsive effort can be improved by the roughness that increases drive surfaces 76 and 78.On the other hand, also can from the rubber-like material, select, improving the ability that engages one another of particle and Pan Bi, and improve the efficient that propulsive effort passes to particle in order to the material of making inside

face

76 and 78.

In another embodiment, this equipment can have the outlet conduit of an expansion as shown in figure 19.The cross-sectional plane of the outlet conduit of this expansion is towards the outer opening of this outlet conduit and expansion gradually.The pressure that the outlet conduit of this expansion is applied on the outlet conduit inside face tightly packed granule materials reduces gradually along the direction of the outer opening of this outlet conduit.As a result, by outlet conduit, the friction drag between granule materials and outlet conduit inside face has reduced, thereby has also caused the improvement of the ability of delivery of particulate material material.

And, have realized that the propulsive effort that is produced by equipment depends on that also solid passes through the length of its main transfer passage that moves (for example, this passage among Fig. 5 at inlet 54 and export between 56).Usually, for the width of transfer passage, the length of this passage is long more, and the propulsive effort of equipment is also big more.

As shown in Figure 13 and Figure 14, main transfer passage 250 has the driving length L, makes granular solids from entering the mouth 54 by this length L arrival outlet 56 by driving rotor 68.The height of

rotating disc

66 and 68 drive surfaces is that H and width are W in the main transfer passage 100, and this width W is limited between the

relative face

76 and 78 of rotating disc 66 and 68.The diameter of wheel hub 74 is D, and the cross-sectional plane of main transfer passage 100 can have any suitable shape.In illustrated embodiment, the cross-sectional plane of path 10 0 normally rectangle with foursquare.For equipment, drive the diameter D that length L depends on wheel hub 74, so that the increase of the diameter of wheel hub 74 causes the increase of the driving length L of main transfer passage 100 with rotating disc.This causes the ratiometric of this passage length L and passage width W to increase simultaneously, thereby this has also caused the increase of the particle propulsive effort of this equipment generation.

The propulsive effort that the equipment that has realized that produces further depends on driving length L (L depends on the diameter D of wheel hub in roating plate system), height H and the width W of main transfer passage 100.Especially have been found that the ratio relevant (and proportional relation) of propulsive effort and the driving length L (or diameter D) and the width W of the main transfer passage with square cross section (H=W just), that is, propulsive effort increases with the increase of the ratio of W with L (or D).Find that also for the transmission pipeline 100 (just H is not equal to W) of non-square cross section, propulsive effort is not only relevant with the ratio of L (or D) and W, also relevant (promptly with the proportional relation of H) with H, that is, propulsive effort reduces with H and reduces.

With reference to Figure 15 and Figure 16 this feature can be described.As shown in figure 15, main transfer passage has equal height H and width W (just channel cross-section be shaped as square).Wheel hub has diameter D1, and it limits and drives length L 1.In Figure 16, identical among the height H of main transfer passage and width W and Figure 15, in other words, promptly the cross-sectional plane of transfer passage 100 is identical in Figure 15 and Figure 16.But in Figure 16, the diameter of wheel hub is that the twice of hub diameter is many among Figure 15.The driving length L 2 of main transfer passage is that to drive the twice of length among Figure 15 many among Figure 16.Therefore, for the embodiment of Figure 15, hub diameter D is D1/W with the ratio of transfer passage width, then is D2/W for the embodiment of Figure 16, and here the value of D2/W is that the twice of D1/W value is many.As a result, equipment shown in Figure 16 is compared with equipment shown in Figure 15, can produce bigger propulsive effort (or bigger overcome resistance and the defeated ability of pump).

In addition, main transfer passage 100 as shown in Figure 17 have with Figure 18 in the identical width W of main transfer passage.The diameter D of wheel hub also equates among Figure 17 and Figure 18.But the height H 1 of the drive surfaces of the main transfer passage 100 of qualification is bigger than the H2 among Figure 18 among Figure 17.As a result, the equipment shown in Figure 17 is compared with equipment shown in Figure 180, can produce bigger propulsive effort (or stronger overcome resistance and the defeated ability of pump).

Therefore, from top as can be seen said, the ratio (D/W) of the size of propulsive effort and the ratio (L/W) that drives length L and width W, hub diameter D and width W and at least one ratio that drives in the ratio (L/S) of length L and transfer passage S are relevant.More precisely, have recognized that ratio L/W or ratio D/W or ratio L/S are big more, the propulsive effort of equipment is big more.In addition, height H is big more, and the propulsive effort of equipment is big more.Therefore, can know that the size of device drives power F can be expressed by each following relational expression, relational expression is respectively with L/W, and D/W, L/S are the function of independent variable, just following functional relation:

F=f (L/W); F=f (D/W); F=f (L/S); Or F=f (H).

Generally, when special applications (for example the defeated last inclined-plane of product pump or pump is defeated vertically upward, overcome pressure head and the defeated material of pump and/or cross over the defeated material of preset distance pump) propulsive effort that requires can be determined (for example the inclination angle on inclined-plane, the defeated material of the size of pressure and/or pump need be crossed over the length of distance) by the parameter of various application.Therefore, according to embodiments of the invention, any one value among selection L, D, W, S and the H and their combined value can provide the propulsive effort that is suitable for special applications F.

Preferably, the propulsive effort F of equipment is greater than the defeated pressure P of total pump.The defeated pressure P of pump comprises the pressure of granular solids, at equipment the pressure of the extraneous fluid (gas or liquid) under the situation of product pump input pressure charging system and other resistance.Because F is greater than P, so that equipment can drive granule materials effectively, and the unlikely granular solids that causes slides on the surface of rotating disc.In view of the above, can set up following relational expression:

F 〉=P; Or f (L/W) 〉=P; Or f (D/W) 〉=P; Or f (L/S) 〉=P; Or f (H) 〉=P.

Therefore,, select L according to embodiments of the invention, D, W, any one value or combined value among S and the H can provide the propulsive effort F greater than P.

The orientation of delivery side of pump pipeline and shape also influence granular solids are transferred to the ability of pressure greater than the outlet side of entrance side.For example, utilize in the equipment 300 as shown in figure 19 with label 302 expressions towards last outlet conduit, make the service requirement of improving pump input pressure charging system become possible (identical reference number is used to indicate and the similar parts of the employed parts of device shown in Figure 4) with efficient.

The end portion 304 of an outlet conduit 302 is connected on the pressure charging system 306.Preferably, outlet conduit towards last (for example, the end that is connected in the outlet conduit on the pump is lower than the other end of this outlet conduit), so that granule materials is being discharged from outlet conduit 302 and upwards driven before entering the pressure charging system 306.A wall of outlet conduit 302 or a plurality of wall be orientation upwards, and consequently, in fact pipeline has constituted one and held the container that those are driven through the granule materials of outlet conduit.

During transporting by means of the propulsive effort of pump, be limited to the granule materials that moves among each wall of outlet conduit, all be sent to outlet conduit than low side as other granule materials.Simultaneously, also act on the granule materials that is limited in the outlet tube wall at the gravity of outlet side and gaseous tension and fluid pressure.Pump transported between the departure date, and in any given moment, the granule materials that is limited in the outlet conduit wall is compacted and fills up outlet conduit in-to-in trend.As a result, in fact granule materials has formed tamper motion or dynamic, it can barrier gas or liquid enter the path of the driving pipeline of pump from outlet side.

In addition, the granule materials than low side (for example near driving the pipeline place) of outlet conduit is compressed and gets tightr with compacting, thereby the particle bridging part that makes main transmission pipeline or drive in the pipeline 100 more is tending towards strengthening, and this also makes the pump transmission of drive force be tending towards strengthening for the ability of unstable solid thereupon.Because this accumulation is to the result of outlet conduit 302 effects, total system can overcome than the remarkable high outlet side pressure of entrance side pressure to be moved.

Aforesaid propulsive effort improves feature (size that for example just has the driving wall of sudden change place and drive pipeline than and discuss) and has strengthened this effect of accumulation more.The ability of improved transmission of drive force causes the improvement of bridge joint and enters the improvement of the granule materials transmission of outlet conduit, this again then improved dynamic tamper, thereby make pump overcome pressure and the defeated ability of pump is improved.Therefore, to the improvement of the ability of granule materials transmission of drive force and the improvement of outlet conduit configuration and/or orientation, and between them each other with the combination of the mode of cooperation and stack, thereby constituted that a kind of remarkable improvement overcomes pressure and the pump of the defeated ability of pump.

In these preferred embodiments, outlet conduit 302 has an abducent cross-sectional plane (from connecting the end of transfer passage or driving pipeline 100, expanding gradually) on the direction of the end 304 that connects pressure charging system 306.Because the cross-sectional plane terminad part 304 of outlet conduit 302 is expanded gradually, so granule materials is at compaction's step-down on the direction of the end portion 304 of outlet conduit 302, the result, on the direction of outlet conduit end 304, particle acts on the power on outlet conduit wall 305 inside faces, and the friction force between granule materials and the outlet conduit wall 305 has reduced.Therefore, when improving with the outlet 302 that makes progress when bearing high-voltage ability, do not need substantially to improve in order to drive the propulsive effort of granule materials by the equipment 300 of outlet conduit.

The present invention has designed the length of delivery piping 302 preferably, to such an extent as in the defeated process of pump, any moment all remains on sufficient material in the outlet conduit 302, thereby supports and bear higher pressure.Owing on the inside face of wall 305, exert pressure by the granule materials of outlet conduit 302, so the most handy low-friction material of inside face of wall 305 (polytetrafluoroethylene for example, and other super high molecular weight material) coats, to reduce the friction force of granule materials and wall 305.

On the other hand, the propulsive effort of equipment 300 can be enhanced so that granule materials can towards on outlet in overcome the higher friction resistance and move.As a result, can form the stronger cascade humidification (cascaded reinforcement) of granule materials with the higher pressure of antagonism pressure charging system.

As mentioned above, it is evident that the shape of outlet conduit 302 and being oriented in overcomes pressure head (comprising air pressure head and hydraulic pressure head) and has surprising influence with the ability and the efficient aspect of transporting particulates material material.As previously mentioned, thus the shape of outlet conduit and orientation can be selected to provide desirable pressure control ability for specific pump transports row preferably.

Find, the supercharging (containing gas or the fluid pressure higher than equipment entrance lateral pressure) that drives pipeline or passage be can further improve the ability that air pressure head and hydraulic pressure head move that overcomes by stoping.Correspondingly, the further embodiment of the present invention also provides the exit end that reduces the elevated pressures of slave unit as far as possible to enter the leakage means of the pressure that drives pipeline or path 10 0.Along outlet conduit and/or drive passage or the pressure release of each position of pipeline can reduce or suppress the increasing of pressure of driving passage or pipeline 100 as much as possible.The example of these pressure-relief measures is discussed below.

According to a further embodiment, a check valve system is set in equipment 300, so that when equipment has a small amount of or do not have the granule materials pump to fail, stop the pressurization gas or the liquid access arrangement of pressure charging system 306.For example, in a preferred embodiment, a valve plate 308 is an axle with a pin, is installed on outer end 304 parts of contiguous outlet 302.Fail in the process at the pump of a routine, push away from the granule materials that export 302 discharges and hit valve plate 308, thereby open valve plate 308.On the other hand, when equipment 300 only had a small amount of or do not have granule materials, valve 308 was closed outlet 302 with in the main transfer passage 100 that prevents pressurization gas or fluid access arrangement.

In another embodiment, pressure sensor is provided in order to monitor the pressure in main transfer passage 100 and the outlet conduit 302.Monitored pressure can be used for controlling of being connected with valve plate 308 and raise clothes electric system or other suitable motor (not shown), thereby open or close valve plate 308, so that when equipment did not have granule materials, pressurization gas or fluid can not enter main transfer passage 100.

As mentioned above, in the defeated process of pump, granular solids is compacted in outlet 302 substantially, and the granular solids bridge joint of the cascade of formation sequential movements, or one by the outlet the 302 dynamic tampers that move, it withstands the charging fluid of pressure charging system 306, plays a part sealing (or part sealing).But fluid (gas or liquid) still may permeate by the tiny path that forms between granular solids, even enters inlet 54.

Just as mentioned above, for stoping and preventing that fluid permeability from entering inlet 54, equipment 300 can be installed a pressure relief system to drain fluid pressure.For example, as shown in figure 19, a pressure relief system 311 is installed in outlet 302 places (this pressure relief opening can be installed in the position than the more approaching main transfer passage 100 in position shown in Figure 19) of contiguous main transfer passage 100, or is installed on the casing and outer hoop that is adjacent to rotating disc 66 or 68.Pressure relief opening 311 can connect a pumping plant (not shown), to pump the fluid that passes granular solids and infiltrate.In other words, fluid pressure itself may be enough to control pressure relief opening.More preferably pressure relief opening 311 has a valve 312, in order to optionally to close or to open pressure relief opening 311.Pressure relief system can be installed in along on any correct position of main transfer passage 100.For example, pressure relief opening can be installed in outer hoop 92 or connect on boundary's part 314.In the better implement example, disk and casing or outward the gap between hoop or the wheel hub suitable pressure release outlet can be provided.

The present invention has designed the length of delivery duct 100 preferably, so that in delivery duct 100, has produced bridge joint accumulation, cascade of sufficient amount, thereby supports and born the elevated pressures of delivery side of pump side.This can finish by means of shrinkage type pipeline, constant section duct or extended pattern plumbing system.Extended pattern plumbing system (at this, the main pipeline that drives is expanded to outlet from inlet) is favourable to pump input pressure charging system.In more detail, extended pattern pipeline 100 in fact, is shrinking towards the direction of inlet from outlet, thereby can stop the granule materials that is transmitted because of reverse any motion by pump under the effect of cut-back pressure.

In addition, find that the supercharging of delivery duct helps equipment to overcome air pressure head or hydraulic pressure head and the defeated ability of pump in the supression equipment.Many embodiment of the present invention provide the measure of restraining the delivery duct supercharging.Further embodiment also provides the size of equipment and configuration to improve the operation under the pressure.

In order to prevent that particle and granule dust from embedding casing 52 and each

rotating disc

66 and 68 outer intermarginal spaces, as shown in Figure 12, rotating disc comprises an oblique inclined-plane 72 away from casing 52, stretches out as the outward flange of rotating disc inside face.Preferably the outer rim of rotating disc forms the inclined-plane with an angle that is about 45 degree.

A dust eduction gear 74 that has auxiliary valve 76 also can be equipped with in the bottom of casing, so that the dust that may accumulate in the defeated process of pump is discharged (Figure 19).Between the pump on-stream period, valve 76 can often leave, and can be got rid of continuously when falling into the dust eduction gear with convenient dust by interior collection channel (not shown).As a kind of possible alternative, valve 76 can be normally closed, has only when interior collection channel is filled dust and just open.Certainly, valve 76 is Chang Kai or normally closed, depends on dirt and the frangibility that are transmitted material.The open and close of valve 76 can preestablish by user's wish.

The size that drives rotor can alter a great deal, and it depends on the type and the volume of the material of carrying or

measuring.Rotating disk

66 and 68 external diameter scope generally can be from several inches to several feet.Less rotating disk is applicable to carries relative less solid material with metered volume, for example food additives and medicine.Larger-size rotating disk can be used to carry and measure a large amount of organic and inoganic solids materials, comprises raw-food material, coal, stone and analogue.Present device is well suited for being used to carry and measures big and little particle and composition thereof, and the solid material of big or little volume, also can be used to carry and measure dried or wet granule materials.Unique restriction is that the material that is transferred and measures can not be too wet, otherwise can disturb bridge joint because of big viscous force.

Though the above-mentioned embodiment that provides is to use mono-to drive rotor, also might design the load transfer device with a plurality of driving rotors, this equipment can be accepted material from single or multiple inlets.Use a plurality of driving rotors, can increase the loading and unloading capacity of material and needn't increase the diameter of rotating disk.

The bridge joint of solid causes the forward of solid to move.In view of the above, pump both can be used as load transfer device, also can be used as metering outfit.Because the solid positive movement by pump,, and be that benchmark calculates and just can finish metering by the solid flow of pump with the cross-sectional area of pipeline therefore by measuring the speed of rotation that drives rotor.When being used as measuring pump, preferably utilize some monitoring equipments commonly used, guarantee in the whole process of solid metering, all to be full of solid in the conduit at any time.These monitoring equipments commonly used comprise gamma rays and dynamo-electric monitoring device.These monitoring devices are known in the art, thereby have not both provided in the drawings, also are not described in detail.
