Abstract

The utility model discloses a filtering crushed material stirring machine and aims to provide a stirring machine which is low in manufacturing cost and capable of saving energy and labor, meeting process requirements on homogenization effect and crushing stones. The key points of technical scheme of the utility model include: a filtering grating plate is arranged between a front helical blade and a back helical blade, or in front of the front and back helical blades or in one of the front and back helical blades to separate a cylinder sleeve at the position where the filtering grating plate from a front cylinder sleeve and a second cylinder sleeve to form rear, middle and front cylinder sleeves, and at the same time, jacks are arranged above and below or on the left and right of an outer edge between the rear and middle cylinder sleeves and springs are arranged above and below or on the left and right of an outer edge between the middle and front cylinder sleeves. In case of hard materials difficult to crush, the rotating helical blades push the middle cylinder sleeve a certain distance ahead to enlarge the distance between a blade outlet and the filtering grating plate, so hard materials is allowed to exceed and pass and crushed after the process is repeated for multiple times; or the jacks stretch forward to push the middle cylinder sleeve to expose the hard materials to discharge the hard materials.

Description

A kind of filtering type particle mixer

Technical field the utility model relates to that processing industry is done prior pulverizing to raw material and the employed a kind of plant equipment of homogenizing is called mixer or mixer.

The technical background denumerable Bricks and Tiles Plant that also must use with the most use, pug mill with the Bricks and Tiles Plant is an example, its structure and acting principle be as shown in Figure 1: double joint stirs major axis 1, and to be installed in open type mud cylinder be in the tank diameter 2, a plurality of paddle 3 usefulness screw rods add nut 4 minutes all around altogether four direction with equidistant and stagger mutually and be installed on the major axis, the double joint that is driven by power stirs major axis together with together inwardly rotation of paddle, wherein one be left-handed one for dextrorotation, because paddle is that an inclined-plane promptly meets at right angles with axle is non-, on-stream raw material constantly is fed forward.Its weak point is, because most raw materials will add a certain proportion of water in advance, the adding of water is easy to make the local glomeration of raw material, this ball it to be difficult to obtain disperse form with pinching mill batch mixing in stirring irregular, chasing after its reason is not difficult to find: can obviously see three clay streams (comprising other raw materials) that walking speed is different in the running, promptly middle faster than both sides, this is because the axle of two parallel installations is gone up its paddle cause of a stack overlap joint part each other in rotation, article three, the clay stream chance that is difficult to mix and stir, its surface layer is not subjected to any resistance on the water as floating, because it is the space that there is certain distance in the front and back paddle, do not say handstone, also incompetent unable to harder walk, entering thus behind subordinate's mud extruder (brick and tile blank molding machine) is a kind of raw material of doing wet and plucked, is cut into the difference that occurs easily behind the tile blank tire on the size, causes bending, distortion, even problems of crack, power consumption is also more in addition, also has deficiencies such as paddle easy fracture.

Summary of the invention the utility model is at above-mentioned deficiency, aim to provide a kind of simple in structure, in light weight, cost is low, power consumption less and the good particle homogenizer of mixing effect, be achieved by the following technical solutions.

With former open type tank diameter wherein a part change the sealed cylinder sleeve that promptly becomes into, and in the closed cylinder sleeve, single track is installed according to technological requirement, the above screen (filter plate) that filters of two pass or two pass, it filters screen and adds that by several circles not of uniform size several a tree, used in making timber for boats that lead are formed, leave between circle and the circle certain space confession raw material in extruding, surmount by, but do not get rid of its filtration screen and add that by inside and outside only two circles some inside and outside linearities of connection lead a tree, used in making timber for boats and formed, a plurality of circle bars add the way of leading a tree, used in making timber for boats its objective is for reduce raw material in surmounting resistance and help improving work efficiency because the screw reamer in circular void and the running to walk the journey route corresponding.In order to prevent jam both sides width is made in the same space between the two adjacent rings bar and differed, promptly move towards outlet and be wider than inlet according to raw material.It is that reamer together rotates that shaft band in the running connects the helical blade that is installed on the shaft, because helical blade is a helical form to be enclosed in axle and go up to form certain lift angle and impel raw material to shift forward promptly to push forward, when arriving filter plate inlet one side for the raw material of helical form circuit reach, owing to having applied certain resistance to raw material, the existence of filtering screen makes the comparatively loose raw material closely knit certain air of getting rid of that becomes, hard thing under the extruding of screw reamer in the raw material is milled and crushed most powdering surmounts from a plurality of slits of filtering screen together with raw material, has obtained thus to cut apart and has mixed and stirred.

In order more to help crushing hard material and prevent to exist in the raw material and be difficult to broken hard thing and enter cylinder sleeve as bigger stone and caused the accident by jam at the filter plate inlet; make single displaceable movable with the one section cylinder sleeve that filters screen is installed; promptly as long as itself and front and back cylinder sleeve disconnection are become an independent accessory; its cross dimensions rear end certain-length strengthens; the front end certain-length reduces; middle constant; the back is added the outer rim that general goal is linked in the back cylinder sleeve; the front reduces to locate to be linked in the inner edge of front cylinder sleeve; and after during the outer rim of somewhere and front jar sheath follower head and back cylinder sleeve front end is installed with cylinder sleeve length washer at an angle of 90 before totally three roads are divided into respectively in the middle of movable cylinder sleeve; the catch that need not be shifted also can be installed on the fixing support; simultaneously; in mounting spring between the preceding and middle catch with between back and middle catch jack is installed; the installation position of spring and jack can be about or only few up and down promptly two in pairs. when meeting when being difficult to for the moment broken hard thing under the thrust at screw reamer; thereby hard material is pushed into to impel between outlet of screw reamer top and the filter plate and filters screen together with movable cylinder sleeve reach certain size; filtering screen and the distance of top, the screw reamer front certain space of formation of will changing from small to big like this makes way for hard material and passes through; the spring of this moment is compressed; it is the back side in spiral on the contrary that hard thing is shifted from the front hyperspace of spiral; this moment, spring stretched again; such process repeats till hard thing is ground through several times; be that the every fortune of the screw reamer not broken hard thing of the tangible mill of of repetition that circles is shut down the back and moved movable cylinder sleeve reach by trying hard to recommend of protracting of jack and allow hard thing expose to be excluded. for discovery in time can be installed alarm or red colored lamp, touch switch by the automatic shift of movable cylinder sleeve and just can realize.

For the through screen that filters of the big stone of stopping to be difficult to crush; change double leaf head or leafy head and will be close to the screw reamer blade that filters screen into by Dan Yetou; promptly have like the multiple-blade electric fan such; make the single propelling passage of raw material become two passages or a plurality of passage; passage section is corresponding to be reduced thereby make; big stone is kept off before leafy head thus, then shut down and get rid of.

According to related screw reamer of technological requirement shaft and cylinder sleeve can be paperback, upright dress (vertical) or angle mount, screw reamer when vertical the installation in the running down pushes raw material, screw reamer is connected the counter-pressure of this formation and shaft is up lifted, weight according to shaft and screw reamer can be offset part or all with counter-pressure, can install counterweight additional shaft upper in case of necessity and offset counter-pressure fully and be as the criterion, realize energy-conservation purpose with this to reach.

When level is installed, both can be that folk prescription is to extruding, also can be that the symmetrical expression twocouese pushes, promptly structure is identical but helical blade (reamer) that rotation direction is opposite is installed in the two ends, the left and right sides of same axis with two groups in case of necessity, one of its rotation direction is left-handed one and is dextrorotation, push toward two from middle according to the direction of rotation of axle and helical blade or with raw material while and equivalent in the running, or with raw material also equivalent past middle propelling movement simultaneously from two, cancelled out each other and do not had by having to become in the two ends that the formed counter-pressure of in-line bidirectional pushing drops on same axis, main shaft band in promptly turning round connects helical blade to be pushed away raw material forward, formed counter-pressure helical blade is connected and main shaft (shaft) to pusher, unidirectional propelling movement that Here it is don't fail to be installed the cause of thrust bearing in the main shaft somewhere, because having the existence of thrust bearing that it is retreated becomes and can not just can keep normal running, ball and front and back catch (fixed circle and moving-coil) according to its thrust bearing of size of counter-pressure rub, and this friction must be with the consumption certain energy as cost.When selecting the symmetrical expression bidirectional pushing for use, be divided into and run in the opposite direction and head-on come up according to the trend of raw material, the effect of its counter-pressure or axle drawn toward two from middle, or past centre pushes away from two, same pulling force or same thrust drop in is at one time cancelled out each other on the same axis and is no longer existed, and promptly eliminates the only remaining radial load of axial force in the running and energy-conservation.

Before both can being installed in helical blade according to its filter of technological requirement was the front of reamer head, the space of helical blade (reamer) gap before and after also can being installed in, for improve filter screen (filter plate) intensity in case in extruding, be out of shape, and the one side of feed(raw material)inlet is made the taper that inner ring is higher than the outer ring, promptly be an inclined-plane that rises from outside to inside, the gap that the contiguous place of its inclined-plane and reamer head keeps minimum is as the criterion not collide.Such filter plate successively decreases the slit by the priority that raw material passes through when above from big to small as twice or twice are installed, and its section increases progressively from small to large, and it is in small, broken bits to realize thick earlier pure back to successively decrease, and increases progressively that to reduce back overall channel area constant in order that reduce resistance filter plate slit.

Both can select for use single shaft also can select twin shaft for use, when selecting twin shaft for use, because that twin shaft adds its material feeding effect of double helix is better and several original paddles can be replaced by helical blade.

For the ease of installing, it filters screen both can be that a full circle also can be two semicircles of two-in-one, when being a full circle, its helical blade is not to be directly installed on the axle, but be divided into some joints be installed in steel pipe around, as long as successively steel pipe socket is combined on the shaft, and be used for installing the filtration screen between two joints of back, its steel pipe is connected fit with axle by pin key, or axle is made six sides or connected fit by side's cover from all directions, and maintenance is also more convenient thus.

To take in case of necessity the material outlet place also make its mass output rate of filter disc formula cylinder sleeve edge week can be higher.

The beneficial effects of the utility model are summarized as follows:

The one, particle, homogenize are effective: as long as the width that filters slit between screen circle bar and the circle bar is set and the road number that filters screen is installed according to technological requirement, just can realize coarse crushing or in small, broken bits and the purpose of mixing and stirring homogenize;

The 2nd, energy and labour saving: filter screen and just can be on the original basis partly shorten the acting of shaft about 1/2nd as long as single track is installed, its mixing quality has good indifference, shorten that shaft is corresponding to have reduced energy resource consumption, particularly when selecting for use the extruding of vertical installation and symmetrical expression twocouese to push owing to offset that counter-pressure is corresponding to have reduced installed capacity;

The 3rd, manufacturing cost reduces: length shortens and means that two-way the extruding of symmetrical expression equals the merit that a machine has been made two machines with the corresponding minimizing of material;

The 4th, be convenient to select for use the way that adds steam to improve raw material plasticity: after raw material is surmounting the filtration screen, to be divided into sheet or powdery, its passage section according to the structure of filtering screen can increase about 1/3rd or two/one or more and form certain space, give to add steam herein a very advantageous conditions is provided.Also have and to change former open type tank diameter into the closed cylinder sleeve in superiority such as production operation are safer.
