Abstract

The invention relates to an inductive hollow spiral pushing device. An integrated spiral ring (2.1) acts and moves in a motor hollow rotor (1) to make a pushed object added into an input port (7), so that the flow volume of the pushed object is increased, and stoke stability is guaranteed. The spiral spring is of a hollow shaftless multi-ring tubular structure and is directly inducted and driven; a sealed shell (6) is completely isolated from the outside, namely, friction between an isolator and a shaft and friction between a driver and the rotor are avoided, and therefore noise is reduced. The inductive hollow spiral pushing device can induct the environment of the pushed object directly and also can regulate the rotation speed and forward or reverse rotation through self-induction, so that the overall pushing efficiency of the inductive hollow spiral pushing device is higher than that of existing pumps, propellers, fans, spiral air compression devices and spiral excavating devices. The inductive hollow spiral pushing device further has the advantages of being free of leakage, coupling, sparks, cavitation and maintenance, low in noise, capable of carrying out speed regulation automatically and rotating reversely, magnetisable, expansible, self-cleaning and long in service life.

A kind of induction cored screw pushing device

Affiliated technical field

Type patent of the present invention relates to a kind of induction cored screw pushing device of new structure.It adopts integrated whorl (2.1,2.2) inner mobile to being pushed away thing acting at motor sleeve rotor (1), being pushed away thing comprises liquid, gas, software, granular solids, liquid and granular solids mixture, gas and liquid vapour mixture and all kinds of mixture fluid, pushed away the flow capacity of thing and promoted stroke thereby improved, making integrated pushing efficiency exceed existing pump, propeller cavitation, fan, spiral air-pressure equipment and spiral excavating device.Whorl is the tubular structure that adopts the many rings of hollow shaftless multi-turn, directly responded to driving, and housing (6) and the outside of sealing isolate completely, cancelled the friction of spacer and axle, and friction between driving and rotor, so reduced noise pollution.Can directly be there is oneself's induction adjustment rotating speed and clockwise and anticlockwise ability to pushing away substance environment simultaneously, and have the Complex interface (10) of external energy drives.

In the time promoting liquid or gas, it can stop to be pushed away thing completely and extraneous leakage is polluted, especially at flammable liquid or gaseous environment, without friction, no-spark, so safe and reliable.Under bad working environments, it can effectively prevent from being pushed away other foreign matter in thing winding, impact or stop.It relies on from belt sensor (9), as temperature, pressure and external sensing signal instruction are adjusted speed governing variation and stoppage protection automatically.To the substance environment that pushed away of hot water composition, it can remove incrustation scale automatically, avoids passage to stop up.When food biological is carried, after spontaneous magnetization, can be used for other thorough fare.To being pushed away the dirt of thing, after shutdown, can oneself clean without dismounting.It utilizes Complex interface (10) can depart from electric power energy and promotes.So due to these structural features, except raising the efficiency, it has without leaking, without being coupling, no-spark, low noise, from speed governing, can reverse, magnetisable, can expansion, self-cleaning, non-maintaining, long lifetime.

Background technique

At present, rotation promotes class device pump, propeller cavitation, fan, spiral air-pressure equipment, screw press apparatus and spiral excavating device.

Pump structure mainly contains centrifugal pump, screw pump, helico-centrifugal pump, magnetic drive pump, Archimedes's pump.But in some application operating modes, the efficiency of centrifugal pump only has 30%.It is high that the driving of screw pump connects complex maintenance cost.Helico-centrifugal pump belongs to Novel integrated pump, but there is leakage at its live axle place.Magnetic drive pump just solves pump shaft and reveals its efficiency and but do not improve a lot.Archimedes's pump is also because drive and cause the friction of axle and seal ring to be revealed with motor shaft.

It is lower that centrifugal pump transmits promotion efficiency, mainly pushed away after thing is spent by pump housing passage bending 90 in transmission pushing course and produced obstruction force, it is two because the centrifugal blade of pump is more very large, and the operation amplitude of oscillation is large, so itself and body clearance are larger, therefore there is no suction capacity, under the lower operating mode of some liquid levels, cannot work.

In order to improve the efficiency of pump motor, has used brushless electric machine and directly driven, but its connection complexity does not reduce, the thing that pushed away of pump shaft joint is still revealed, and pump shaft and seal ring noise large.

In addition, while conventionally clearing up inner dirt after pump long-term work, the pump housing need to be opened, self-clean cannot be realized.

The structure of propeller cavitation is center tape spool, and propeller blade is distributed in surrounding, in the form of sheets, power be from central shaft enterprising enter, by be pushed away thing be liquid or gas.

The each section of propeller cavitation, in the time being pushed away the work of the large angle of attack of thing comparison of resistance, could obtain larger Driving force, under less resistance torque, just understands efficiency higher.Because when propeller cavitation work, axial velocity is not with change in radius, and tangential velocity is with change in radius.Therefore approaching blade tip, radius larger part flow angle is less, and corresponding blade angle also should be less.And approaching blade root, and radius smaller part flow angle is larger, and the impact in corresponding blade angle and axle center is also very large.Also because blade tip has friction strength radially to do centrifugal idle work in tangent direction all the time, central shaft area accounts for more than 20%, and the displacement that is pushed away thing is blocked in front, so its efficiency in the time running up continues to reduce.

Meanwhile, propeller bearing wearing and tearing, and oar shaft sealing can not thoroughly solve, and when operation, between centers friction, produces noise effect surrounding enviroment, periodic maintenance is changed frequent.

In addition, the power of propeller cavitation is taking electric power as main, even if adopt high efficiency motor to drive, but axle connects complicated and rotational energy consumption is serious.

Fan structure is similar propeller cavitation, and being pushed away thing is gas.Work long hours, the software foreign matter automatic absorbing in gas, on blade, is caused to decrease in efficiency.Although fan power also adopts high efficiency motor to drive at present, because the diameter of fan blade far-end in the time running up shortens with distinguished and admirable aggravation, cause whole efficiency to decline.

Rotation air-pressure equipment adopts the promotion of rotation rod-type more, and motivational drive employing motor, even if use high efficiency motor also cannot avoid because axostylus axostyle is out of shape the distortion friction bringing and does negative work, causes the low maintenance of rate frequently.

Screw press apparatus adopts shaft rod type to advance more, and shaft rod type advances, and squeezing tank space is accounted for much by center bolt, and edge extrudate is at helical-blade far-end gap leakage, drives and connects complexity, and whole volume is larger.If outlet extruding is stopped up, screw rod is out of shape or damages.

Spiral excavating device adopts shaft rod type to advance more, and power transmits from axostylus axostyle, and the radius due to spiral while propelling is in advance larger, at center root, axostylus axostyle joint is easily formed to complications, causes causing the transmission of axostylus axostyle distortion moment and weakens, and when serious, cannot work.

In addition, spiral promotes class device taking electric drive as main at present, but in environment that can be abundant at mechanical energy, liquid or gas pressure, cannot realize without the simple connection transforming and driving.

In conjunction with the practical application of existing spiral pushing device, specifically describe the application technology of existing slewing gear, as:

On-board engine heat radiation water pump, water seal wearing and tearing and cooling liquid are revealed and part replacement is safeguarded frequent.Tap water serves as cooling liquid and causes radiation system incrustation scale automatically to get rid of, and the resistance of pump increases gradually so that damages.Because heat radiation water pump does not have self-regulating function, cause pump with the long-term invalid circulation waste resource of motor.

The hot water pump that central heating system is used, its inner incrustation scale cannot automatically be removed and cause pipeline to dwindle gradually, needs for a long time artificial unloading's pump housing to safeguard specially.

Central heating and Cooling Air-conditioning System pump, the pump shaft of transport process is revealed, and causes noise larger owing to adopting series excited machine to drive simultaneously.Even if high efficiency motor drives, but axle connection complex maintenance is frequent.

Vacuum cleaner all adopts centrifugal pump body, and adopts high speed series excitation commutator machine, so the large efficiency of noise is low, also because dust granule block pumps causes artificial unloading's clean and maintenance frequent.

The long-term air pump ventilating is all to adopt centrifugal pump body, and adopts high speed series excitation commutator machine, and connection drives complicated, and between centers friction noise is very large.Ventilation fan and blower are also that so noise exceedes 80 decibels.

The centrifugal pump that air compressor adopts, compresses and finds time air, and not only inefficiency, noise are very large, and the leakage of pump shaft gap seriously makes its waste energy.

Daily family expenses pump and pump bowl can not operate with shaking type, and juvenile, old man and handicapped people cannot operate under laborsaving and galianconism condition.

Locomotive oil pump adopts centrifugal damascene structures, even if adopt DC brushless motor high efficiency drive, but also takies very greatly fuel tank internal space because connect complicated volume, needs artificial disassembly, cleaning, the frequent maintenance of salvaging.

The scavenger fan that range hood is used, although adopt single-phase Induction Motor Drive of long lifetime, middle axle center and motor block distinguished and admirable and greasy dirt, complex structure cleaning oil pollution is loaded down with trivial details.

The pump that the occasions such as fish jar, biochemistry, printing and dyeing are used, is wound around and does not have oneself to get rid of function software foreign matter, and also owing to there is no self-induced environment changing capability, so pump motor long-term work wastes energy, a large amount of halfload high pass filter pump works is very waste also.Food and medical treatment situation, the noise pollution of existing pump, and can not effectively stop pump shaft to liquefied article of food nutrient delivery and reveal pollution mutually, more can not improve nutritive active.

Screw extruding bri quetting machine adopts screw type propelling extrusion, in the time that molding port stops up, due to sensing and linkage structure complexity, causes delay of response distortion or damages screw rod.And squeezing tank volume accounted for much by axostylus axostyle, surrounding extrudate is driven in the wrong direction, and even makes the distortion of pivoting leaf far-end under king-sized thrust, causes larger extrudate to be driven in the wrong direction and omits.

Underwater operation propeller cavitation is in the time advancing, and the friction noise between rotating shaft and water seal can be sent to periphery waters, and the water of outside can immerse operating room, cause need to be very large tailing axle Stuffing box carry out pressure type discharge and leak.Meanwhile, operator under water sight line is shorter, and the naked axostylus axostyle being exposed on the external is in the process of pushing ahead, and root joint is because the resistance arm radius of collapsing force more easily causes complications, once will be worked by side swipe.

Airflight thing propeller cavitation is in the time of lifting and flight, blade tip is subject to force unbalance to cause overall flight attitude not steady, meanwhile, the resistance of central shaft is along with the increase resistance of propeller cavitation rotational speed is also increasing, if receive, the interference impeller of unexpected flying object easily causes flying unbalance.Because propeller cavitation needs artificially constantly adjustment to the adjusting of air-flow transmission speed, so in narrow and small place, some large-scale spiral oar applied for machines cannot be rollinged takeoff and land.

Existing spiral Mars Miner is to adopt screw rod structure, when high-power leading mining advances, due to the radius ratio root of digging of spiral, to connect radius large, in the time running into larger excavation, at center root, axostylus axostyle joint is easily formed to tortuous power, cause screw rod deformation efficiency to decline and maybe can not work, and can not directly transport and be adopted thing.

Implement further illustrating type product of the present invention below in conjunction with accompanying drawing

Embodiment

In accompanying drawing 1, the product that the present invention relates to, from Complex interface (10) switches on power, the inner driving block of housing (6) obtains after the instruction of electric power and default logic and sensor (9), driving block (5) produces rotating magnetic field immediately, around distribute to central through bore outer wall in this magnetic field, according to magnetic pole heteropole inhale mutually homopolarity repel principle, rotor outer wall (3) thus being at once subject to induced magnetism rotates rotor (1) Integral synchronous.Simultaneously, the thing that pushed away at housing (6) input port (7) is involved in immediately, in accompanying drawing 2, blade (K) through whorl continues to be involved in, along the inclined thrust surface (H) of whorl, root (T) at whorl (2.1,2.2) is rotated promotion, the frictional force that overcomes rotating ring length (L) except thrust has been done negative work, thrust often turns around and is all done positive work to pushing away thing, until export from housing (6) delivery outlet (8).

Promote power ρ theorem formula: ρ=(fl+mg δ l)/S

F: Driving force

L: promote displacement

M: quality

δ: friction factor

S: time

According to above-mentioned formula, in order to improve promotion efficiency, except reducing friction masterpiece negative work, also should promote the interior promotion volume that is pushed away thing of unit time and do positive work.Its volume depends on the spacing (D) of whorl (2.1,2.2) and promotion face height (H) and the rotational speed of ring.The size of Driving force f depends on the product of quantity and the number of turns of whorl, because different anchor rings is fixing on same rotor (1) inwall, therefore its linear velocity equates, is the equal of that the Driving force of individual pen monocycle is in stack.Meanwhile, whorl (2.1,2.2) roots (T) thickness has enough holding powers to guarantee that thrust exports completely.Although frictional force increases along with the increase of the number of turns and number of rings, along with the long-term existence of whole promotion state, can reduce and promote surperficial friction factor δ significantly, the negative work that rubs can reduce gradually.

When promotion, thrust overcomes and is pushed away thing and in ring, do friction when negative work, can first be rolled to whorl root, because the root (T) of ring is and promotes the integrated connection of sticking point, be equivalent to power arm and lengthen voluntarily, and resistance arm point of action does not become in the centre of ring (H), is greater than resistance arm labour-saving principle according to power arm, whorl radius is larger, promotes efficiency higher.

The angular velocity of the blade (K) of whorl (2.1,2.2) and root (T) angular velocity are identical, the turning radius of its blade (K) approaches 0 to mechanics round dot, so the friction negative work of tangent direction is almost 0, therefore the root (K) that is pushed away thing and be rolled to through the passage of whorl spacing ring, sticking point all does positive work.

Whorl (2.1,2.2) is due to long-term use, its blade wearing and tearing can make height (H) diminish, therefore the height (H) encircling after actual motion a period of time also can be less than 50% of rotor radius (Φ), will inevitably generating portion be pushed away thing omission like this, thus Efficiency Decreasing.For this reason, need to do at the blade of whorl (K) special processing of rub resistance.But ring height (H) be greater than rotor radius (Φ) 50% time, thrust increase, driving velocity reduce, therefore equaling 50% position, be the best joint of speed and thrust.

Angle (G) angle of whorl (2.1,2.2) promotion face and rotor (1) cross section reaches 90 while spending, the promotion power of whorl is 0, so this angle is less, to promote efficiency higher, the number of turns (1 circle=2 π) and the number of ring could arrange a lot, but its friction negative work is also increasing.So, while specifically enforcement, rely on equation with many unknowns model solution to select best parameter.Also can retaining ring blade (K) tangent line parallel constant with rotor (1) tangent line, and reduce its angle in the face of promotion to being less than 90 degree, there is crawl effect to pushing away thing, thereby being pushed away thing landing, minimizing omits.

Although have certain gap between device rotor outer wall of the present invention (3) and housing (6) central bore outer wall, conventionally this gap is less than 10% of rotor (1) diameter, but because two bearings of front and back are played to pushing away thing the effect of blocking, do not promote acting, so there is no positive work loss yet.Just, long-term use to have pushed away thing solid kind residue and entered this gap, cause rotor friction and wearing and tearing.So, within the suitable cycle of operation, must manually open bearing and make an overall screening.

If while adopting electromagnetic coil to do driving block (5) stator output rotating magnetic field, corresponding rotor outer wall (3) is the induced action that permanent-magnet material or inductor coil material can play magnetic force, follows brushless synchronous machine or asynchronous motor principle of rotation.

If adopt machinery to drag magnetic material as stator, while producing rotating magnetic field, corresponding rotor outer wall (3) is that the magnetic material of opposite pole is playing the induced action of magnetic force.Under this structure, also can input the energy beyond certain electric power by comprehensive inlet opening (10), impel mechanical device can drag magnetic material and produce rotating magnetic field, thereby inductiopn rotor (1) is directly with movement and motor-driven integrative whorl (2.1,2.2) synchronously to rotate.

After device of the present invention works long hours, need to clear up the blade of whorl (K) dirt time, because driving block (5) has clockwise and anticlockwise function, need not dismantle inlet opening (7) and delivery outlet (8) and whorl (2.1,2.2) just can be along exchanging counterclockwise automatically rotation.As long as having under power supply or external energy input, after it is stopped operating completely, restart inverted running, just can make the tangent direction dirt of blade (K) be removed by the thing that pushed away of anti-tangent direction, i.e. Automatic clearance.

Apparatus of the present invention are compared pump, propeller cavitation, fan, spiral air-pressure equipment, screw press apparatus and spiral excavating device, because whorl (2.1,2.2) wherein rotates in pipe, its promotion efficiency has improved much theoretically significantly, thereby get rid of existing rotary pushing device rotation centrifugal force and radially done negative work, pushed away thing with eliminating and stopped in central shaft and bearing the mobile negative work of doing that has some setbacks, and get rid of their blade far-end distortions in the time of high speed, cause radius to reduce and cause that linear velocity reduces the problem that invalid promotion increases.

In the time that apparatus of the present invention are worked in pond as water pump, encounter software foreign matter, due to whorl (2.1,2.2) the inside does not have directly and it stops and is wound around obstacle or blade, so High Rotation Speed will make it be released together from encircling smooth promotion surface, reaches non-maintaining object.Can automatically sense variation in water pressure by this sensor (9), thereby automatically regulate rotational speed.

Regard vacuum pump in the time finding time to use when apparatus of the present invention, this sensor (9) senses the pressure in gas transport process automatically, thereby automatically regulates rotational speed.

In the time that apparatus of the present invention are regarded biochemical food transfer pump, due to the sealing completely of housing (6), reach and prevent biochemical food and the extraneous object of mutually polluting.To the substance environment that pushed away of different occasions, regulate rotational speed by this sensor (9) self-perception in promotion.Meanwhile, when food nutrition molecule is carried, carry out spontaneous magnetization by the magnetic material of rotor outer wall (3), reach other object.

In the time that apparatus of the present invention are regarded vehicle-mounted water of radiation pump work, it,, without a lot of transmission device and containment measures parts are installed, directly aims at inlet opening (7) and delivery outlet (8).Regulate rotational speed by this sensor (9) self-perception water temperature in the hot water promoting.And hot water dirt can carry out spontaneous magnetization dissolving by the magnetic material of rotor outer wall (3), automatically eliminate.During as vehicle oil pump work, can be directly installed on fuel tank lid position, both increase fuel tank space, also make oil supply system safeguard and simplify.

In the time that apparatus of the present invention are rotated as the air-supply of fan exhausting, because driving block (5) has clockwise and anticlockwise function, inlet opening (7) and delivery outlet (8) need not be dismantled and distinguished and admirable automatic reverse.Meanwhile, this sensor (9) can sense the unlike signal instruction in gas transport process automatically, thereby automatically regulates rotational speed.Special during as vacuum cleaner equipment high speed dust suction rotation, because rotor (1) is sensed driving, and and housing (6) between do not rub, so reducing noise and former series excitation rectification carbon brush abrasion also disappear.

In the time that apparatus of the present invention are sent hot cold wind as electric drier, because the rotor (1) of band movement and motor-driven integrative whorl (2.1,2.2) is sensed driving, so reducing noise and former series excitation rectification carbon brush abrasion also disappear, simplified this product linkage structure simultaneously, volume ratio was dwindled originally, and regulate rotational speed by this sensor (9) self-perception wind-warm syndrome in the hot cold wind promoting.Equally, while use as heat steam humidifier, ion sterilizing fan product, its implementation methods is also like this.

In the time that apparatus of the present invention are regarded hand air pump or pump bowl rotation, as long as at comprehensive inlet opening (10) input hand-operated mechanical device linkage structure, meeting driving block (5) has rotating magnetic field output, just can reach the object of inflating or bleeding.

In the time that apparatus of the present invention are rotated as underwater propeller, can adopt power supply, also can adopt mechanical transmission, enter from comprehensive inlet opening (10).Because housing (6) diameter is greater than the diameter of being with whorl (2.1,2.2) rotors (1); and the diameter of existing propeller cavitation axostylus axostyle is much smaller than the diameter of propeller cavitation; so play protection rotor (1) effect of advancing; encounter the obstacles such as submerged reef even if wipe, also can directly not damage rotor (1).Due to not friction between rotor (1) and the housing (6) of sealing, so reducing noise is compared wearing and tearing between existing screw shaft and water seal and also disappeared.Also because housing (6) is sealing configuration, stop the possibility that deep operating room leaks completely.Because driving block (5) has clockwise and anticlockwise function, inlet opening (7) and delivery outlet (8) need not be dismantled, start and drive instruction, the rotation of whorl (2.1,2.2) automatic reverse, reach the object of the dive of need not turning around directly to float, also directly moment brake rests on certain degree of depth under water.

In the time that apparatus of the present invention are rotated as aircraft propeller, can by its inlet opening (7) upward delivery outlet (8) down perpendicular to ground, after self-powered startup, as long as meet the balance of thrust, gravity and resistance of air, it can directly go up to the air or land.And, by this sensor (9) aloft self-perception air pressure regulate rotational speed, reach automatic adjusting flight balance object.Because driving block (5) has clockwise and anticlockwise function, inlet opening (7) and delivery outlet (8) need not be dismantled driving, distinguished and admirable automatic reverse, and the direct moment brake of need not turning around just can rest on certain traffic altitude.

When apparatus of the present invention are in the time spinning air-pressure equipment work, because housing (6) seals completely, disappear so compare the friction noise of existing equipment sealing gland and axle, and the possibility of body to external leakage of being calmed the anger can not occur.The rotor (1) of band movement and motor-driven integrative whorl (2.1,2.2) is sensed driving, so overall structure is fairly simple, and volume-diminished.

In the time that apparatus of the present invention are worked as screw press apparatus, the import and export of inlet opening (7) and delivery outlet (8) and extrusion equipment are corresponding.Whorl (2.1,2.2) is shaped to taper, or housing (6) is shaped to taper, large mouthful of inlet opening (7) and taper are corresponding, also can suitably increase the height (H) of whorl (2.1,2.2) to improve thrust, the squeezing tank of comparing existing screw extruding bri quetting uses the volume of double-screw type screw extrusion reinforcement little, also expanded squeezing tank space, and compare existing screw type propelling edge extrudate far-end gap leakage and eliminate, driving structure is simple, and overall volume diminishes.In the time that extruding outlet is stopped up; internal pressure can increase, and now sensor (9) or external automatic detection instruction be from comprehensive inlet opening (10) automatic detection, autostop immediately; compare existing extrusion press and stop and will be quick on the draw, brake in time.When will, in extrusion process solid-liquid separation, having sorting hole and housing delivery outlet (8) to have outage in rotor (1) back segment side.

When apparatus of the present invention are in the time spinning excavating device work, on the whorl (2.1,2.2) of locating in the inlet opening (7) of housing, carry out after the resistance to hardness of special high strength is processed connecting corresponding inlet opening (7) and delivery outlet (8).In the time that whole equipment excavates propelling energetically in advance, because whorl diameter is larger, middle part is hollow, can be easily tortuous as the axostylus axostyle joint of existing Mars Miner.In the time running into relatively high power excavation; housing (6) diameter is much larger than rotor (1) diameter of band whorl (2.1,2.2); and the diameter of existing screw rod digs the diameter of head much smaller than spiral; also can protect rotor (1) normally to work, and be dug rear end automatic transportation that thing can directly pass through whorl (2.1,2.2) to outside.

The various application that related at this with relate to future, it improves, approaches or the promotion class device of similar structure of the present invention, is considered as with the present invention identical.Also comprise and associate similar structure and thorough fare and produce other structure-improved and promote series products, be also considered as with the present invention identical.
