Description

Technical Field

[0001] The invention relates to the technical field of filtering devices, and in particular to a bean product processing slurry filtering device and a filtering process. Background Art

[0002] When filtering traditional soy milk slurry, gauze is generally used for filtering. The general practice is to spread out the gauze and then hang it up with a rope to form a bucket-like structure. The soy milk slurry is then poured on the gauze in the bucket-shaped structure. After that, the staff shakes the gauze left and right, and the bean dregs in the soy milk slurry will be filtered on the gauze, thereby achieving the filtration of the soy milk slurry.

[0003] The existing Chinese patent publication number is "CN213466947U" and the patent name is "A filtering device for soy milk production and processing". The filtering device introduced in the patent includes a filtering chamber and a filtered soy milk storage chamber arranged from top to bottom in a main frame, a filter cloth support plate is sealed and fixed at the bottom of the filter chamber, a filter cloth is fixed on the filter cloth support plate, a stirring plate is driven by a driving motor and arranged under the filter cloth, the driving motor is installed on a hydraulic rod 1, the bottom of the hydraulic rod 1 is fixed in the filtered soy milk storage chamber, a filtered soy milk discharge port is provided on one side of the filtered soy milk storage chamber, a filter residue extrusion plate is arranged oppositely at the bottom of the filter chamber, two hydraulic rods 2 are fixedly installed on the outside of each filter residue extrusion plate, a filter residue discharge plate is provided at the outer edge of one side of the filter cloth support plate, and a filter residue storage bucket is provided below the filter residue discharge plate.

[0004] Although the filtering device introduced in the above patent can filter soybean milk, its filtering method is a filter cloth filtering method, which is not much different from the traditional soybean milk slurry filtering method. The filter cloth is equivalent to gauze, and the method of rotating the stirring plate to break up the filter residue is equivalent to shaking the gauze to break up the filter residue, and there is no better filtering effect. Moreover, the method of discharging the filter residue is to push the filter residue out of the filter cloth by a hydraulic rod, and the filter cloth needs to be flattened before discharging the filter residue to ensure that the hydraulic rod can push the filter residue from the filter cloth. However, the above patent does not mention any method of flattening the filter cloth. Therefore, it may be difficult for the hydraulic rod to push the filter residue away from the filter cloth because the filter cloth is not flattened. In addition, the method of using a hydraulic rod to push the filter residue is more troublesome. Summary of the invention

[0054] like Figure 1 As shown, a soy product processing slurry filtering device provided by an embodiment of the present invention includes a shell 100, a conveyor belt 200, a filtering mechanism 300 and an arc plate 400. The shell 100 is provided with a feed port 101 and a discharge port 102. A receiving cylinder 500 is provided in the shell 100. A slag inlet is provided at the top of the receiving cylinder 500. The receiving cylinder 500 is provided with a slag discharge cylinder 501 extending out of the shell 100.

[0055] The housing 100 may be a coverless container-like device capable of holding slurry or a coverless housing with sealed joints. The receiving tube 500 may be a long strip-shaped cylinder with an unsealed top. The receiving tube 500 is fixed between the inner walls of the front and rear sides of the housing 100. The receiving tube 500 does not contact the bottom plate of the housing 100 in the housing 100. Both ends of the receiving tube 500 may be arc-shaped ends. The arc-shaped end of the receiving tube 500 away from the bottom plate of the housing 100 is bent in a direction away from the bottom plate of the housing 100, and the arc-shaped end of the receiving tube 500 close to the bottom plate of the housing 100 is bent in a direction close to the bottom plate of the housing 100.

The slurry flows from the feed port 101 to the discharge port 102, and the slurry can be pumped out of the shell 100 from the discharge port 102 by equipment such as a pump arranged outside.

[0056] A discharge barrel 103 may be fixed on the shell 100 . The discharge barrel 103 is a hollow barrel. The discharge barrel 103 is fixed at the position of the discharge port 102 . The discharge barrel 103 is communicated with the discharge port 102 . The filtered slurry may flow out from the discharge barrel 103 .

[0057] like Figure 1-Figure 4 As shown, the conveyor belt 200 is arranged on the accommodating cylinder 500, and a driving assembly 600 is arranged between the housing 100 and the accommodating cylinder 500, and the conveyor belt 200 can rotate around the accommodating cylinder 500 through the driving assembly 600. Two conveyor belts 200 can be arranged, and an annular groove can be provided on the front and rear side plates of the accommodating cylinder 500. The annular groove is similar to the profile of the front and rear side plates of the accommodating cylinder 500, and the annular groove is provided on the end surfaces of the front and rear side plates of the accommodating cylinder 500. The conveyor belts 200 correspond to the two annular grooves respectively, and are respectively sleeved in the two annular grooves. Driven by the driving assembly 600, the two conveyor belts 200 can rotate around the circumference of the front and rear side plates of the accommodating cylinder 500.

[0058] The filter mechanism 300 is arranged on the conveyor belt 200, and the filter mechanism 300 includes a support frame 310 and a filter plate 320. There are multiple filter plates 320, and the multiple filter plates 320 are all rotatably arranged in the support frame 310, and can slide in the support frame 310. The multiple filter plates 320 are hinged at the head and tail to form a folded filter plate structure, and the hinged ends of the folded filter plate structure are spaced apart with limit sleeves 323 parallel to the hinge direction.

[0059] Specifically, a plurality of filter mechanisms 300 are provided on the conveyor belt 200, and the plurality of filter mechanisms 300 are evenly distributed along the length direction of the conveyor belt 200. The filter plate 320 may be a rectangular metal plate with numerous small holes, and the support frame 310 may be a rectangular frame, and the length direction of the filter plate 320 is parallel to the length direction of the shorter frame beam on the support frame 310. The filter plate 320 is a rectangular plate with a plurality of filter holes evenly distributed, and the two ends of the filter plate 320 are respectively rotatably connected between the longer frame beams on both sides of the support frame 310. Of course, the filter holes on the filter plate 320 may also be of different sizes. A rotating shaft may be fixed at both ends of the filter plate 320, and the length direction of the rotating shaft may be parallel to the length direction of the filter plate 320, and the rotating shaft may be located on the central axis of the filter plate 320. The filter plate 320 is rotatably connected to the longer frame beams on both sides of the support frame 310 through the rotating shafts at both ends thereof. There are multiple filter plates 320, and the multiple filter plates 320 are hinged end to end to form a folded plate structure, that is, a folded filter plate structure. At least two limit sleeves 323 are provided, and the limit sleeves 323 are arranged at intervals at the hinged ends of the folded filter plate structure, and the limit sleeves 323 are all located at the end of the filter plate 320 away from the conveyor belt 200.

[0060] like Figure 1-Figure 8 As shown, the arc plate 400 is located at the top of the accommodating tube 500, and the arc plate 400 is bent in the direction away from the accommodating tube 500. A limiting groove 410 is opened on the side of the arc plate 400 facing the accommodating tube 500, and the limiting sleeve 323 on the fold line filter plate structure is inserted into the limiting groove 410. When the fold line filter plate structure slides along the limiting groove 410, the adjacent filter plates 320 in the fold line filter plate structure can squeeze the filter residue and discharge the filter residue into the accommodating tube 500, so that the filter residue is discharged from the shell 100 from the residue discharge tube 501.

[0061] The arc plate 400 may be a plate fixed to the top of the accommodating tube 500 by a fixing rod, and the arc plate 400 is bent in a direction away from the accommodating tube 500. The limiting groove 410 is provided on the surface of the arc plate 400 on one side of the arc plate 400 facing the accommodating tube 500, and the two ends of the limiting groove 410 are respectively connected to the two ends of the arc plate 400. There can be at least two limit grooves 410, and the number of limit grooves 410 can be equal to the number of limit sleeves 323, and each limit sleeve 323 corresponds to a limit groove 410. When the folded filter plate structure formed by hinged connection of multiple filter plates 320 follows the conveyor belt 200 to rotate around the receiving tube 500, the limit sleeves 323 at the hinge axis on the folded filter plate structure can be respectively inserted into the corresponding limit grooves 410, and as the folded filter plate structure moves, the angle between adjacent filter plates 320 will change. When the angle between adjacent filter plates 320 becomes smaller, it means that the filter plate 320 is pressurizing the filtered filter residue, and the filter residue can be squeezed into a block after pressurization. In the process of the folded filter plate structure moving from one end of the limit groove 410 to the other end, the filter residue squeezed into a block on the filter plate 320 will slide from the filter plate 320 into the receiving tube 500, and then discharged from the housing from the slag discharge tube 501.

[0062] In summary, in this embodiment, when filtering the slurry, the conveyor belt 200 rotates circumferentially around the receiving tube 500 under the drive of the driving assembly 600, and the multiple filtering mechanisms 300 can rotate synchronously with the conveyor belt 200. When the conveyor belt 200 rotates, the filter plate 320 in each filtering mechanism 300 can filter the slurry in the housing 100, thereby achieving multiple filtration of the slurry, so that the present invention has a better filtering effect. After filtering the slurry, the filter plate 320 will enter the area of ​​the curved plate 400 synchronously with the support frame 310, and the filter plate 320 will be sent to the area of ​​the curved plate 400 as the conveyor belt 200 rotates. At this time, the limit sleeve 323 on the hinge shaft of the filter plate 320 can enter the corresponding limit groove 410. When the limiting sleeve 323 moves along the limiting groove 410, the angle between adjacent filter plates 320 will increase or decrease. When the angle decreases, it means that the adjacent filter plates 320 squeeze the filter residue therebetween, and the filter residue after squeezing can form a block. The filter residue formed into the block will slide from the filter plate 320 into the containing tube 500 in the process of bypassing the top tube mouth of the containing tube 500, and then be discharged from the residue discharge tube 501 of the containing tube 500, thereby realizing the cleaning of the filter residue.

[0063] In this embodiment, the conveyor belt 200 can drive the filter plates 320 in the plurality of filter mechanisms 300 to rotate, thereby filtering the slurry multiple times. Compared with the prior art, multiple filtering of the slurry can improve the filtering effect of the slurry. In addition, when the filter plate 320 moves with the conveyor belt 200, when the limit sleeve 323 moves in the limit groove 410, the adjacent filter plates 320 can squeeze the filter residue to form a filter residue block. When the filter plate 320 passes through the arc region of the arc plate 400, the filter residue on the filter plate 320 can slide from the filter plate 320 to the receiving tube 500, and then be discharged from the slag tube 501. Compared with the prior art, the filter plate 320 in this embodiment is hard compared to the filter cloth, and the filter residue can slide directly from the hard filter plate 320 into the receiving tube 500, and the technical solution of this embodiment can realize the discharge of the filter residue without additional assistance, which is simple and convenient compared to the existing method of discharging the filter residue.

[0064] In some embodiments, the feed port 101 and the discharge port 102 are respectively located on both sides of the accommodating cylinder 500, the feed port 101 and the discharge port 102 are both located at the upper part of the housing 100, and the discharge port 102 is located below the feed port 101. The movement direction of the slurry from the feed port 101 to the discharge port 102 is opposite to the rotation direction of the conveyor belt 200.

[0065] In this embodiment, the feed port 101 may be a top port of the housing 100, which is located on one side of the accommodating cylinder 500. The discharge port 102 may be opened on any one of the four sides of the housing 100, but it is necessary to ensure that the discharge port 102 and the feed port 101 are respectively located on both sides of the accommodating cylinder 500. The discharge port 102 and the feed port 101 are both located at the upper part of the accommodating cylinder 500, and the discharge port 102 is located below the feed port 101 in the length direction parallel to the accommodating cylinder 500 and is relatively close to the feed port 101.

[0066] Moreover, when injecting slurry into the housing 100, since the discharge port 102 is relatively close to the feed port 101 in the length direction parallel to the containing tube 500, it takes a while for the injected slurry to reach the discharge port 102, so the slurry will first settle in the housing 100, and only when the injected slurry can enter the discharge port 102 can the slurry be discharged from the discharge port 102. The location of the discharge port 102 improves the filtering effect of the slurry to a certain extent, and combined with the subsequent filtering mechanism 300 filtering the slurry, the slurry can be filtered more completely.

[0067] The rotation direction of the conveyor belt 200 is opposite to the direction in which the slurry moves from the feed port 101 to the discharge port 102, so that the filter plate 320 can have a better filtering effect on the slurry. In addition, during the rotation of the conveyor belt 200, the slurry input from the feed port 101 can continuously flush the rising surface of the filter plate 320, which can reduce the probability of filter residue clogging the filter holes and is beneficial to the normal filtration of the slurry.

[0068] Furthermore, if Figure 1-Figure 9 As shown, the limiting groove 410 includes a first arc groove 411, an S groove 412 and a second arc groove 413. The first arc groove 411 and the S groove 412 are both located in the same half section of the arc plate 400. The S groove 412 is located above the feed port 101, and the S groove 412 and the feed port 101 are both located on the same side of the accommodating cylinder 500. Both ends of the S groove 412 are connected to the first arc groove 411 and the second arc groove 413 respectively. The second arc groove 413 is located on the extension path of the first arc groove 411 on the arc plate 400. The limiting sleeve 323 on the folded filter plate structure will first enter the first arc groove 411, then enter the S groove 412, and finally detach from the arc plate 400 from the second arc groove 413. When the conveyor belt 200 drives the folded filter plate structure to move along the S groove 412, the angle between adjacent filter plates 320 will become smaller or larger. When the angle becomes smaller, the corresponding filter plate 320 can squeeze the filter residue.

[0069] Specifically, the extension path of the first arc groove 411 and the extension path of the second arc groove 413 overlap, the first arc groove 411 is connected to one end of the arc plate 400, the second arc groove 413 is connected to the other end of the arc plate 400, and the S groove 412 is located between the first arc plate 400 and the second arc plate 400. The S groove 412 and the first arc groove 411 are both located in the same half section of the arc plate 400, the S groove 412 is located above the feed port 101, and both are located on the same side of the accommodating cylinder 500. It is ensured that when the slurry is transported into the housing 100 in this embodiment, the direction in which the slurry moves from the feed port 101 to the discharge port 102 is opposite to the rotation direction of the conveyor belt 200, so that the filter plate 320 can filter the slurry better.

[0070] When the folded filter plate structure rotates with the conveyor belt 200 and enters the area covered by the curved plate 400, the limiting sleeve 323 on the folded filter plate structure will first enter the first curved groove 411, then enter the S groove 412, and finally leave the curved plate 400 from the second curved groove 413; since there are at least two limiting sleeves 323 in the folded filter plate structure, there should also be at least two corresponding limiting grooves 410, that is, there should also be at least two S grooves 412, and each limiting sleeve 323 corresponds to one S groove 412. It should be noted that adjacent limiting grooves 410 are symmetrical to each other.

[0071] When the conveyor belt 200 drives the limiting sleeve 323 on the folded filter plate structure to move along the corresponding limiting groove 410, the angle between adjacent filter plates 320 does not change during the process of the limiting sleeve 323 moving from the starting end of the first arc groove 411 to the end of the first arc groove 411;

[0072] When the limiting sleeve 323 enters the S groove 412 and moves along the S groove 412, in the process of the limiting sleeve 323 moving from the starting end of the S groove 412 to the first turning point of the S groove 412, the adjacent limiting sleeves 323 will approach each other. During this period, the filter plates 320 between the adjacent limiting sleeves 323 will squeeze the filter residue, and the angle between the filter plates 320 will become smaller.

[0073] In the process of the limiting sleeve 323 moving to the first inflection point of the S groove 412 and then moving to the second inflection point of the S groove 412, the adjacent limiting sleeves 323 will change from being close to each other to being away from each other. During this period, the filter plates 320 between the adjacent limiting sleeves 323 will release the squeezed filter residue, and the angle between the filter plates 320 will gradually recover and increase to the angle state just entering the first arc groove 411, and then increase. When the limiting sleeve 323 moves to the second inflection point of the S groove 412, the angle between the filter plates 320 between the adjacent limiting sleeves 323 will be at the maximum state.

[0074] In the process of the limiting sleeve 323 moving to the second inflection point of the S-groove 412 and moving toward the end of the S-groove 412, that is, the starting position of the second arc groove 413, since the extension path of the second arc groove 413 coincides with that of the first arc groove 411, the angle between the filter plates 320 between adjacent limiting sleeves 323 will gradually return to the angle state just entering the first arc groove 411.

[0075] When the limiting sleeve 323 enters the second arc groove 413 from the S groove 412, no matter how the angle between adjacent filter plates 320 changes when the limiting sleeve 323 moves in the S groove 412, after the limiting sleeve 323 enters the second arc groove 413, the angle between adjacent filter plates 320 will mostly return to the angle between adjacent filter plates 320 when the limiting sleeve 323 moves in the first arc groove 411. However, when the limiting sleeve 323 passes through the S groove 412, the angle between the filter plates 320 between adjacent limiting sleeves 323 will inevitably change from large to small, then from small to large, until it returns to its original state. As long as the angle between the filter plates 320 becomes smaller, it means that the filter plates 320 have squeezed the filter residue.

[0076] In this embodiment, the bending span of the S groove 412 is relatively large. When the limiting sleeve 323 passes through the S groove 412, the angle between adjacent filter plates 320 will inevitably increase or decrease first, then return to its original state, then decrease or increase again, and finally return to its original state. The filter plate with a reduced angle can squeeze the filter residue between the filter plates 320 into blocks. When two adjacent filter plates 320 move with the conveyor belt 200, the filter plates 320 can move around the top of the receiving tube 500, thereby realizing the flipping of the filter plates 320. When the filter plates 320 flip, the filter residue blocks between the filter plates 320 will fall into the receiving tube 500 from the residue inlet of the receiving tube 500, and finally be discharged from the residue discharge tube 501.

[0077] In some embodiments, the first arc groove 411 may also be a groove body with variable width, and the groove width of the first arc groove 411 at the end of the arc plate 400 is greater than the groove width at the connection between the first arc groove 411 and the S groove 412. The groove width setting of the first arc groove 411 not only makes it easier for the limiting sleeve 323 to slide into the first arc groove 411, but also helps the limiting sleeve 323 slide from the first arc groove 411 to the S groove 412, and can guide the sliding of the limiting sleeve 323.

[0078] In some embodiments, Figure 1-Figure 3 and Fig.10 As shown, a first path groove 502 extending around the accommodating cylinder 500 is opened on the accommodating cylinder 500, and the conveyor belt 200 includes a driving belt 210 and a mounting plate 220. The driving belt 210 is sleeved on the first path groove 502. The driving belt 210 can rotate along the first path groove 502 through the driving assembly 600.

[0079] In this embodiment, the accommodating cylinder 500 is a long strip-shaped cylinder with arc-shaped ends at both ends, similar to the accommodating cylinder 500 in the aforementioned embodiment. The top of the accommodating cylinder 500 is provided with a top port, which facilitates the filter plate 320 to discharge the filter residue into the accommodating cylinder 500 when it moves along the limiting groove 410 and passes through the accommodating cylinder 500. The first path groove 502 is the same as the annular groove in the aforementioned embodiment, and is provided with two. The two first path grooves 502 are respectively opened on the front and rear side plates of the accommodating cylinder 500, and both are around the accommodating cylinder 500. The driving belt 210 can be a hoist belt, which adopts a special reinforced tear-resistant polyester canvas and is equipped with a steel wire tear-proof layer, which can greatly reduce the possibility of the driving belt 210 being torn during operation. There are two driving belts 210, and the two driving belts 210 are respectively set in the two first path grooves 502, and can rotate along the first path groove 502 under the action of the driving assembly 600. The mounting plate 220 is fixed on the belt surface of the two driving belts 210 away from the bottom of the first path groove 502, and the length direction of the mounting plate 220 is perpendicular to the length direction of the driving belt 210 and the length direction of the accommodating cylinder 500. There are multiple mounting plates 220, and the multiple mounting plates 220 are evenly distributed along the driving belt 210, and each mounting plate 220 is provided with the filtering mechanism 300 in the above embodiment.

[0080] Furthermore, the driving assembly 600 includes a driving motor 610 and a driving roller 620. A mounting frame 110 is provided on the outer wall of the shell 100, the driving motor 610 is mounted on the mounting frame 110, the driving roller 620 is rotatably disposed in the accommodating cylinder 500 and is located at the bottom end of the accommodating cylinder 500, the driving belt 210 is sleeved on the first path groove 502 and bypasses the driving roller 620, the driving roller 620 is pressed against the inner belt surface of the driving belt 210, and the output shaft of the driving motor 610 is inserted into the shell 100 and is coaxially connected to the driving roller 620.

[0081] Specifically, the mounting frame 110 can be a square tube fixed on the front side wall or the rear side wall of the housing 100, and the driving motor 610 is installed in the square tube, and the output shaft of the driving motor 610 faces the housing 100. The front and rear sides of the accommodating cylinder 500 are both provided with a rotating wheel groove, which is located at the bottom end of the accommodating cylinder 500. The rotating wheel groove is a circular groove, and the cross-sectional center of the rotating wheel groove is concentrically arranged with the cross-sectional center of the bottom arc end of the accommodating cylinder 500, and the cross-sectional radius of the rotating wheel groove is equal to the cross-sectional radius of the bottom arc end of the accommodating cylinder 500. The driving roller 620 includes a roller shaft and a roller wheel, and the two ends of the roller shaft are respectively rotatably connected to the front and rear side plates of the accommodating cylinder 500 and respectively penetrate the adjacent side plates of the housing 100, and the length direction of the roller shaft is parallel to the length direction of the mounting plate 220. There are two roller wheels, which are respectively located in the rotating wheel grooves on the front and rear sides of the accommodating cylinder 500 and are respectively fixed at the two ends of the roller shaft, and the roller shaft, the roller wheel and the rotating wheel groove are coaxially arranged. A rotating wheel may be installed at one end of the roller shaft passing through the housing 100, and a belt may be installed on the rotating wheel. A driving wheel may be installed on the output shaft of the driving motor 610, and the belt is sleeved on the rotating wheel and the driving wheel. When the driving motor 610 is running, it can drive the roller shaft to rotate through the belt, thereby driving the driving belt 210 to rotate around the first path groove 502.

[0082] Of course, in this embodiment, the output shaft of the driving motor 610 can also be coaxially arranged with the roller shaft, and the output shaft of the driving motor 610 is fixedly connected to one end of the roller shaft that passes through the side plate of the housing 100. The driving belt 210 sleeved in the first path groove 502 is sleeved on the roller wheel on the corresponding side, and the inner belt surface of the driving belt 210 can be tightly pressed against the arc-shaped wheel surface of the roller wheel.

[0083] The driving motor 610 can provide power for the movement of the filtering mechanism 300 in the housing 100 , making it more convenient for the filtering mechanism 300 to filter the slurry in the housing 100 .

[0084] In some embodiments, Figure 11-13 As shown, the support frame 310 is a telescopic frame, and the support frame 310 includes an end rod and a telescopic rod, and two end rods and two telescopic rods are provided, and the two telescopic rods are fixed between the two end rods. The filter plate 320 is movably arranged in the support frame 310, and a rotating shaft 321 is fixed on the filter plate 320 parallel to the central axis of the end rod, and both ends of the rotating shaft 321 are rotatably connected to movable blocks 322, and the movable blocks 322 at both ends of the rotating shaft 321 are respectively slidably arranged on the two telescopic rods. The movable blocks 322 close to the end rod are fixedly connected to the end rod, and springs are connected between adjacent movable blocks 322.

[0085] Specifically, the end rod and the telescopic rod are perpendicular to each other, the end rod includes a first end rod 3112 and a second end rod 3122, the telescopic rod includes a first side rod 3111 and a second side rod 3121, the first side rods 3111 corresponding to the two telescopic rods are respectively vertically fixed at both ends of the first end rod 3112, and the second side rods 3121 corresponding to the two telescopic rods are respectively vertically fixed at both ends of the second end rod 3122. The first side rod 3111 and the second side rod 3121 are slidably connected. The movable block 322 is slidably connected to both the first side rod 3111 and the second side rod 3121.

[0086] The first side bar 3111 may be provided with a slot hole parallel to the length direction thereof, and the second side bar 3121 may be inserted into the slot hole and move along the length direction of the slot hole. A slide groove parallel to the length direction of the second side bar 3121 may be provided on one side of the second side bar 3121 close to the slot hole wall, and a slide bar parallel to the length direction of the slot hole may be fixed on the slot wall close to the second side bar 3121, and the slide bar in the slot hole may be inserted into the slide groove on the second side bar 3121 and slide along the slide groove, thereby realizing the sliding connection between the second side bar 3121 and the first side bar 3111, that is, realizing the extension and retraction of the telescopic rod.

[0087] The length direction of the filter plate 320 is parallel to the length direction of the first end rod 3112 and the second end rod 3122, and the rotating shaft 321 is fixed on the filter plate 320 at the center axis parallel to the first end rod 3112. There can be one or two rotating shafts 321 on each filter plate 320. When there is one rotating shaft 321, the rotating shaft 321 is fixed at the center axis of the filter plate 320 and its two ends extend out of the filter plate 320 respectively. When there are two rotating shafts 321, the two rotating shafts 321 are respectively fixed at the two ends of the filter plate 320 and are both coaxially arranged with the center axis of the filter plate 320. In this embodiment, there is only one rotating shaft 321 on each filter plate 320.

[0088] The movable block 322 is rotatably arranged at both ends of the rotating shaft 321 and is slidably arranged on two telescopic rods. The movable block 322 is fixed with a first slide bar 3221, a second slide bar 3222 and a third slide bar 3223 on the side facing the corresponding first side bar 3111. The first slide bar 3221, the second slide bar 3222 and the third slide bar 3223 are arranged at intervals, and the second slide bar 3222 is located between the first slide bar 3221 and the third slide bar 3223. A first slide groove 313 and a second slide groove 314 are provided on a side wall of the first side bar 3111 facing the inside of the support frame 310. The first slide groove 313 and the second slide groove 314 are both parallel to the length direction of the first side bar 3111 and are respectively located on both sides of the slot. A third slide groove 315 parallel to the length direction of the second side bar 3121 is provided on a side wall of the second side bar 3121 facing the inside of the support frame 310. When the movable block 322 is slidably set on the telescopic rod, the first slide bar 3221 is inserted into the first slide groove 313 and contacts the groove wall of the first slide groove 313, the second slide bar 3222 is inserted into the second slide groove 314 and contacts the groove wall of the second slide groove 314, and the third slide bar 3223 is inserted into the third slide groove 315 and contacts the groove wall of the third slide groove 315, thereby realizing the sliding of the movable block 322 on the first side rod 3111 and the second side rod 3121. When the first slide bar 3221, the second slide bar 3222 and the third slide bar 3223 slide in the corresponding first slide groove 313, the second slide groove 314 and the third slide groove 315, a limiting structure can be set between the first slide bar 3221 and the first slide groove 313, between the second slide bar 3222 and the second slide groove 314, and between the third slide bar 3223 and the third slide groove 315 to ensure that the first slide bar 3221, the second slide bar 3222 and the third slide groove 3223 will not separate from the corresponding slide groove when sliding in the corresponding first slide groove 313, the second slide groove 314 and the third slide groove 315. The limiting structure can be a similar structure to the second side rod 3121 sliding in the slide groove in the slot hole through the slide bar.

[0089] The springs fixedly connected between adjacent movable blocks 322 can ensure that when the support frame 310 returns to its original state after extension and retraction, the movable blocks 322 and the filter plates 320 rotatably arranged on the movable blocks 322 can also return to their original state, facilitating the next extension and retraction of the support frame 310. The springs provide a push or pull force for the movable blocks 322 to restore their original position.

[0090] In this embodiment, Figure 11-Figure 15As shown, the support frame 310 is movably arranged on the mounting plate 220 through a shaking mechanism, and the shaking mechanism includes a fixed plate 710, a limit plate 720, a driving plate 730 and a rotating assembly 740. The fixed plate 710 is fixed on the mounting plate 220, and both ends of the fixed plate 710 are slidably provided with receiving sliders 711, the first end rod 3112 and the second end rod 3122 are respectively rotatably arranged on the two receiving sliders 711, the limit plate 720 is fixed on the first side rod 3111 close to the mounting plate 220, the driving plate 730 is slidably arranged on the limit plate 720, and the rotating assembly 740 is arranged between the accommodating cylinder 500 and the driving plate 730.

[0091] The fixed plate 710 is a plate member parallel to the length direction of the mounting plate 220, and a sliding rod can be fixed at both ends thereof, and a receiving slider 711 is slidably arranged on the sliding rod, and the sliding direction of the receiving slider 711 is perpendicular to the length direction of the fixed plate 710. The sliding structure between the receiving slider 711 and the sliding rod can be similar to the sliding structure of the slide bar inserted into the slide groove mentioned above. The first end rod 3112 and the second end rod 3122 are respectively rotatably arranged on the two receiving sliders 711, and the rotation mode between the first end rod 3112, the second end rod 3122 and the corresponding receiving slider 711 can be rotation by hinged mode. The limiting plate 720 is fixed on the first side rod 3111 close to the mounting plate 220, and is away from the first end rod 3112 on the first side rod 3111. The limiting plate 720 is parallel to the mounting plate 220 and the fixed plate 710. The driving plate 730 is a plate parallel to the limiting plate 720. A guide groove parallel to the length direction of the limiting plate 720 can be opened on the side of the limiting plate 720 away from the inner frame of the support frame 310. The driving plate 730 can be inserted into the guide groove and can slide along the length direction of the guide groove, thereby realizing a sliding connection between the driving plate 730 and the limiting plate 720.

[0092] like Figure 11-Figure 18 As shown, the rotating assembly 740 includes a rotating drum 741, a stop block 742, and a driving shaft 743. The rotating drum 741 is fixed to the side of the driving plate 730 facing the fixed plate 710. The end of the rotating drum 741 away from the driving plate 730 penetrates the fixed plate 710 and the mounting plate 220. The rotating drum 741 is rotatably connected to the fixed plate 710 and the mounting plate 220. The stop block 742 is fixed with a driving shaft 743, which is inserted into the rotating drum 741. The accommodating cylinder 500 is provided with a first path groove 502 (combined with the first path groove 502). Figure 3The limiting groove 230 is parallel to the limiting groove 230, and a limiting assembly is arranged between the limiting block 742 and the limiting groove 230. The limiting block 742 is inserted into the limiting groove 230 and can slide along the limiting groove 230. When the limiting block 742 slides in the limiting groove 230, the limiting block 742 can reciprocate in the direction parallel to the groove depth of the limiting groove 230 under the action of the limiting assembly. A power assembly 800 is arranged between the driving shaft 743 and the rotating drum 741. When the driving shaft 743 reciprocates along the groove depth direction of the limiting groove 230 with the limiting block 742, the driving shaft 743 can drive the rotating drum 741 to reciprocate through the power assembly 800, thereby causing the driving plate 730 to rotate synchronously.

[0093] Specifically, the rotating drum 741 can be fixed at the center of the driving plate 730, and the central axis of the rotating drum 741 can pass through the center of the driving plate 730. The end of the rotating drum 741 away from the driving plate 730 is provided with an opening, and the end surface of the end can pass through the fixed plate 710 and the mounting plate 220 and be flush with the side surface of the mounting plate 220 away from the fixed plate 710. The rotating drum 741 can be rotatably connected with the fixed plate 710 and the mounting plate 220 through a bearing, so that the driving plate 730 can rotate with the rotation of the rotating drum 741. The driving shaft 743 fixed on the limit block 742 can be inserted into the rotating drum 741 from the opening of the end of the rotating drum 741 away from the driving plate 730. The two ends of the accommodating cylinder 500 can be fixed with an arc rod, and the two ends of the arc rod are respectively fixedly connected to the left and right side plates of the accommodating cylinder 500, and are located in the middle of the end of the accommodating cylinder 500. The arc of the arc rod is parallel to the arc of the ends of the front and rear side plates of the accommodating cylinder 500. The limiting groove 230 can be provided on the outer side wall of the accommodating cylinder 500, the limiting groove 230 is located in the middle position of the left and right sides of the accommodating cylinder 500, the arc portion of the limiting groove 230 is provided on the arc rod at the end of the accommodating cylinder 500, and the limiting groove 230 is parallel to the first path groove 502. Under the action of the limiting assembly and the power assembly 800, when the limit block 742 moves in the limiting groove 230 along the groove depth direction of the limiting groove 230, the rotating cylinder 741 can be reciprocated on the fixing plate 710 and the mounting plate 220, thereby causing the driving plate 730 to rotate synchronously.

[0094] When the driving plate 730 rotates, the first end rod 3112 and the second end rod 3122 can slide on the corresponding receiving slider 711, and the sliding directions of the first end rod 3112 and the second end rod 3122 are opposite, so that the support frame 310 is tilted, and the support frame 310 is extended, that is, the first side rod 3111 and the second side rod 3121 slide, and the distance between the first end rod 3112 and the second end rod 3122 increases. The greater the distance between the first end rod 3112 and the second end rod 3122, the more the folded filter plate structure arranged in the support frame 310 is stretched, that is, the larger the coverage area of ​​the filter plate 320 in the support frame 310, the larger the area that can contact the slurry, and the better filtering effect can be achieved on the slurry.

[0095] When the driving shaft 743 moves back and forth with the limit block 742 in the groove depth direction of the limiting groove 230, the driving plate 730 can rotate back and forth therewith, thereby enabling the support frame 310 to rotate synchronously, that is, achieving the shaking of the support frame 310. During the reciprocating rotation of the support frame 310, the coverage area of ​​the filter plate 320 in the support frame 310 will be large and small, and the angle between adjacent filter plates 320 will also be large and small. When the angle between adjacent filter plates 320 is reduced, the filter residue between two adjacent filter plates 320 can be squeezed, and the filter residue after squeezing can form a block, which is easier to slide into the accommodating tube 500 when the filter plate 320 moves to the top of the accommodating tube 500. In addition, the shaking support frame 310 can make it difficult for the filter residue to block the filter holes of the filter plate 320.

[0096] In some embodiments, the limiting assembly includes a second path groove 241 and a limiting shaft 242. The second path groove 241 is provided on the groove walls on both sides of the limiting groove 230. The limiting shaft 242 is fixed on both sides of the limit block 742. When the limit block 742 is located in the limiting groove 230, the two limiting shafts 242 are respectively inserted into the two second path grooves 241 and can slide along the second path groove 241. The second path groove 241 includes a straight groove portion 2411 and a folded line groove portion 2412. The straight groove portion 2411 is connected to the folded line groove portion 2412. The folded line groove portion 2412 is located in the housing 100 and on both sides of the accommodating cylinder 500. When the limiting shaft 242 slides along the folded line groove portion 2412, the limit block 742 can reciprocate along the groove depth direction parallel to the limiting groove 230 when the limiting groove 230 slides.

[0097] Specifically, the second path groove 241 is an annular groove formed by connecting a straight groove portion 2411 and a folded line groove portion 2412, wherein the folded line groove portion 2412 is provided on a portion of the groove wall of the limiting groove 230 located inside the housing 100, and the straight groove portion 2411 is provided on a portion of the groove side wall of the limiting groove 230 extending out of the housing 100. The groove walls on both sides of the straight groove portion 2411 are continuous smooth surfaces, while the groove walls on both sides of the folded line groove portion 2412 are folded line-shaped curved surfaces. The straight groove portion 2411 can be located in the middle of the groove wall of the limiting groove 230 on the groove wall of the limiting groove 230, and the bending direction of the folded line groove portion 2412 is close to the groove opening of the limiting groove 230 or close to the groove bottom of the limiting groove 230 along with its folded line profile. It should be noted that the angles at the bending places of the folded line groove portion 2412 are all obtuse angles or folded line groove portions 2412. The bend of 12 is directly rounded, and when the limit block 742 moves in the limiting groove 230, the limiting shafts 242 on both sides thereof can slide through the obtuse bend or the rounded bend of the fold line groove 2412 more easily and smoothly, so that when the limit block 742 passes through the fold line groove 2412, the limit block 742 can slide smoothly and smoothly in the direction of the depth of the limiting groove 230, and it is also convenient for the drive shaft 743 to be inserted into or extended out of the rotating drum 741 more smoothly.

[0098] The reciprocating motion of the drive shaft 743 inserted or extended in the drum 741 can drive the drum 741 to rotate forward or reverse around its axis under the action of the power assembly 800, and then drive the support frame 310 to rotate synchronously, so as to realize the reciprocating shaking of the support frame 310. When the support frame 310 shakes back and forth, it will drive the second side rod 3121 to slide on the first side rod 3111, and then drive the angle between adjacent filter plates 320 to increase or decrease. When the angle between adjacent filter plates 320 increases, the area of ​​the folding filter plate structure can be expanded, and more slurry can be filtered. When the angle between adjacent filter plates 320 decreases, the adjacent filter plates 320 can squeeze the filtered filter residue, so that the filter residue forms a block, which is more convenient for the subsequent discharge of the filter residue. At the same time, the shaking support frame 310 can also greatly reduce the possibility of the filter residue blocking the filter holes of the filter plate 320.

[0099] In some embodiments, the power assembly 800 includes a driving groove 810 and a driving block 820. The driving groove 810 is opened on the inner wall of the rotating drum 741, and the driving block 820 is fixed on the side wall of the driving shaft 743. The driving block 820 is slidably set in the driving groove 810. When the driving shaft 743 moves in the rotating drum 741, the driving block 820 can be against the groove wall of the driving groove 810 and can drive the rotating drum 741 to rotate.

[0100] In this embodiment, the chute is a smooth trough body, and multiple chute can be opened on the inner wall of the rotating drum 741, and multiple chute are evenly spaced along the circumference of the inner cylinder mouth of the rotating drum 741. If the side cylinder of the rotating drum 741 is unfolded, a rectangular plate will be formed. At this time, the chute is tilted on the rectangular plate and leads to one end face of the rectangular plate, which is the end face of the cylinder mouth of the rotating drum 741. Multiple chute can be evenly spaced along the length direction of the end face. The driving block 820 can be a convex block fixed on the side wall of the driving shaft 743, and the convex block can be a block such as a hemisphere or a cylinder that can be inserted into the chute. There are also multiple driving blocks 820, and multiple driving blocks 820 are evenly distributed on the side wall of the driving shaft 743 around the cross-sectional circumference of the driving shaft 743. Multiple driving blocks 820 are respectively adapted to multiple chute, and when the driving shaft 743 is inserted into the rotating drum 741, the driving block 820 is inserted into the corresponding chute.

[0101] When the driving shaft 743 reciprocates with the limit block 742 in a direction parallel to the depth of the limiting groove 230, since the rotating cylinder 741 is rotatably connected to the fixed plate 710 and the mounting plate 220, there is no movement in a direction parallel to the axial direction of the rotating cylinder 741. Therefore, the driving block 820 fixed on the side wall of the driving shaft 743 can abut against the side wall of the inclined groove and can push the rotating cylinder 741 to rotate. When the driving shaft 743 reciprocates in a direction parallel to the depth of the limiting groove 230, the driving block 820 can push the rotating cylinder 741 to reciprocate, thereby realizing telescoping.

[0102] The present invention also introduces a soy product processing slurry filtering process, such as Figure 1-Figure 15 As shown, the process includes the following steps:

[0103] S1: Loading, pouring the unfiltered slurry into the housing 100 from the feed inlet 101 .

[0104] S2: Filtration, the conveyor belt 200 is driven to rotate on the receiving tube 500 through the driving assembly 600, and the conveyor belt 200 drives the filter plate 320 to rotate around the receiving tube 500 through the support frame 310. The movement of the filter plate 320 can filter the slurry in the shell 100.

[0105] The driving motor 610 for controlling the rotation of the driving roller 620 is started. The driving motor 610 drives the driving roller 620 to rotate, and then drives the driving belt 210 mounted on the accommodating cylinder 500 to rotate. The rotation of the driving belt 210 can drive the mounting plate 220 to move, and then drives the fixing plate 710, the driving plate 730 and the limit block 742 to move. The limit block 742 can move along the limiting groove 230; when the limit block 742 moves in the limiting groove 230, the limit block 742 can reciprocate in a direction parallel to the groove depth of the limiting groove 230 under the action of the limiting shaft 242 and the second path groove 241, and then drives the driving shaft 743 to move synchronously; when the driving shaft 743 moves, the driving block 820 on its side wall can push the inclined groove in the rotating drum 741, and then causes the rotating drum 741 to reciprocate. The rotating drum 741 can drive the driving plate 730 to rotate back and forth, thereby driving the supporting frame 310 to rotate back and forth. The supporting frame 310 can be extended and retracted when rotating back and forth, thereby making the angle between adjacent filter plates 320 larger or smaller; the angle between adjacent filter plates 320 becomes larger, and the area covered by the filter plates 320 becomes larger, so that the filtering effect of the filtering device is better; the angle between adjacent filter plates 320 becomes smaller, and the filter plates 320 can squeeze the filter residue, so that the filter residue is squeezed into blocks, which is more conducive to the discharge of the filter residue;

[0106] When the limiting block 742 moves in the limiting groove 230, the limiting sleeve 323 on the folded filter plate structure will enter the corresponding first arc groove 411, and then enter the S groove 412. When the limiting sleeve 323 moves in the S groove 412, it can drive the filter plate 320 between two adjacent limiting sleeves 323 to clamp the filter residue and squeeze the filter residue into blocks. Then the limiting sleeve 323 enters the second arc groove 413 to complete the movement of the filter plate 320 around the top of the accommodating tube 500; when the limiting sleeve 323 moves along the limiting groove 410, the filter residue blocks on the filter plates 320 between adjacent limiting sleeves 323 can slide from the filter plate 320 into the accommodating tube 500, and be discharged from the shell 100 through the residue discharge tube 501 of the accommodating tube 500, thereby completing the discharge of the filter residue and further realizing the filtration of the slurry.

[0107] S3: discharging the filtered slurry out of the housing 100 from the discharge port 102 .

[0108] In the present invention, it is necessary to continuously inject slurry into the housing 100 through the feed port 101, and the above-mentioned drive motor 610 is started while injecting the slurry. The folded filter plate structure formed by the filter plate 320 can filter the slurry during movement. When the injected slurry reaches the discharge port 102, the discharge port 102 is opened or a suction device is used to discharge the slurry reaching the water level of the discharge port 102 from the housing, thereby realizing the discharge of the slurry. The filter residue in the slurry discharged from the discharge port 102 is less, and the slurry is filtered.

[0109] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
