Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation, in particular to a kaolin high-pressure membrane filter. Background Art

[0002] A diaphragm filter is a solid-liquid separation device that has a diaphragm plate with an elastic membrane installed between the filter plate and the filter cloth. By passing high-pressure liquid or gas medium into the diaphragm plate, the elastic membrane expands and squeezes the liquid to be filtered, thereby pressing the filter cake and squeezing out the liquid in the filter cake for filtration.

[0003] The prior art discloses a Chinese patent with publication number CN 113577856 B: an intelligent high-pressure diaphragm filter press, and discloses a control device, a pushing device and a filter cake detection device, wherein the heat expansion plate is heated by an electric heating plate so that the heat expansion plate expands and pushes the filter cake out of the filter tank, and when the heat expansion plate fails to push the filter cake out, the electric heating plate is pushed out, thereby pushing the filter cake out of the filter tank.

[0004] However, the above-mentioned prior art still has certain defects, that is, during use, the ejection of the filter cake needs to rely on precise electrical components for control, which is not convenient for subsequent operation and maintenance, and the unloading of the filter cake adopts a passive ejection design.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] The kaolin of the present invention is a kind of inorganic non-metallic material in the new material industry, belonging to a part of inorganic non-metallic minerals, and the high-pressure membrane filter is a part of solid-liquid separation equipment, which is used for cleaning, filtering and dehydrating kaolin.

[0049] Example 1

[0050] Refer to the instruction manual Figure 1-3 A kaolin high-pressure membrane filter according to an embodiment of the present invention comprises a filter press section and a material receiving section, wherein the filter press section is composed of a mounting frame 2 and a filter press mechanism 3, a water washing mechanism 4 and an air supply mechanism 5 mounted on the mounting frame 2, and the material receiving section is composed of a mounting platform 1 and a filter cake processing mechanism 7 mounted on the mounting platform 1, and the mounting frame 2 is fixedly mounted on the top of the mounting platform 1 by locking bolts;

[0051] The mounting frame 2 includes two parallel U-shaped main beams, both ends of the bottom of the two U-shaped main beams are fixedly connected with supporting square columns, and a T-shaped plate 9 and a straight plate 10 are fixedly connected between the two supporting square columns at the corresponding ends of the two U-shaped main beams.

[0052] It should be noted that the present invention utilizes the water washing mechanism 4 to fully clean the sludge trapped inside the filter chamber on the filter press mechanism 3, and then utilizes the air supply mechanism 5 to squeeze out the cleaned sludge inside the filter chamber on the filter press mechanism 3, and in the process of squeezing out the water to remove the filter cake, utilizes the filter cake processing mechanism 7 to compact and shape the fallen filter cake for later transportation.

[0053] Specifically, Figure 2-3 As shown, the filter press mechanism 3 includes a mounting seat 31 and a thrust plate 32 respectively fixedly mounted between the two ends of the two U-shaped main beams by locking bolts, a cylinder 33 is fixedly mounted on one end of the mounting seat 31, a pressing plate 34 and a plurality of diaphragm plates 35 are slidably mounted between the two U-shaped main beams, a telescopic end of the cylinder 33 is fixedly connected to the pressing plate 34, and a tensioning assembly 36 is provided between adjacent diaphragm plates 35;

[0054] A feed pipe 37 and a recoil pipe 38 are fixedly installed in the middle of the thrust plate 32 and the pressure plate 34 respectively. A confluence cavity is also opened in the middle of the pressure plate 34, and through holes connected to the confluence cavity are opened at the four corners of the side of the pressure plate 34 facing the diaphragm plate 35. A drain pipe 39 connected to the confluence cavity is fixedly provided at the bottom of the pressure plate 34. Control valves 1 are installed on the recoil pipe 38 and the drain pipe 39, and the water outlet end of the drain pipe 39 movably passes through the T-plate 9.

[0055] It should be noted that, in the process of treating the target kaolin, the target kaolin is first conditioned to form sludge, and at the same time, the compression plate 34 is driven by the cylinder 33 to push the diaphragm plate 35 to move in the direction of the thrust plate 32, so that multiple diaphragm plates 35 are compressed to form a number of closed filter chambers (i.e., the cavity surrounded by two adjacent diaphragm plates 35 after being fitted together), and then the sludge formed after conditioning is pumped into each filter chamber through the feed pipe 37 by a sludge pump. During this period, the control valve 1 on the backflush pipe 38 is in a closed state, so that the injected sludge will not be discharged from the backflush pipe 38.

[0056] Specifically, Figure 4-7As shown, the diaphragm plate 35 includes a square frame 351, a square ring groove is provided in the middle of the inner side of the square frame 351, and through holes are provided at the positions corresponding to the through holes at the four corners of the square frame 351, a bracket 352 is fixedly provided in the middle of the inner side of the square ring groove, a sleeve 1 353 is movably sleeved on the inner side of the bracket 352, and a sleeve 2 354 is movably plugged into the inner side of one end of the sleeve 1 353, wherein, during the entire filter pressing operation, the sleeve 1 353 and the sleeve 2 354 are always in a plugged state at one end close to the bracket 352;

[0057] Both ends of the inner side of the square ring groove are provided with movable frames 355, and push tubes 358 are fixedly provided at the positions corresponding to the perforations of the two movable frames 355. Ring blocks 356 are fixedly provided at the four corners of the middle part of the inner side of the square ring groove, and a connecting pipe 357 is fixedly penetrated inside the ring block 356. The two ends of the connecting pipe 357 are respectively movably inserted into the corresponding push tubes 358. Among them, the inner sides of the opposite ends of the two push tubes 358 are provided with circular grooves, and when multiple diaphragm plates 35 are pressed to form a plurality of filter chambers, the two ends of the connecting pipe 357 are just completely connected. The corresponding annular groove is completely filled, so that a closed cylindrical drainage channel is formed between the push cylinder 358 and the connecting pipe 357. Both ends of the outer side of the connecting pipe 357 are sleeved with a straight spring 359 that fixes the connecting ring block 356 and the corresponding movable frame 355. When the straight spring 359 is in a natural state, the opposite sides of the two movable frames 355 on the diaphragm plate 35 are tightly fitted with the inner wall of the square annular groove under the action of the corresponding straight spring 359. At the same time, the opposite ends of the two push cylinders 358 extend out of the corresponding through holes (such as Figure 7 As shown), the inner sides of the two movable frames 355 are respectively fixedly connected to the outer sides of the corresponding ends of the sleeve 1 353 and the sleeve 2 354 with a diaphragm 3510;

[0058] A square ring-shaped embedding groove is provided on the inner side of both ends of the square ring groove and on the side opposite to the two movable frames 355, and an air bag 3512 is fixedly connected between the square ring embedding groove on the inner side of the square ring groove and the square ring embedding groove on the outer side of the corresponding movable frame 355, and an intake branch pipe 3511 in communication with the corresponding air bag 3512 is fixedly connected at both ends of the outer side of the square frame 351, wherein each intake branch pipe 3511 is installed with a control valve 6, which is used to control the intake branch pipe 3511 to fill gas into the corresponding air bag 3512 after a plurality of diaphragm plates 35 are pressed to form a plurality of filter chambers, so as to fill the concave cavity formed between the movable frame 355 and the corresponding side inside the square ring groove when the two movable frames 355 on the diaphragm plate 35 move toward each other, thereby ensuring that the filter cake can be discharged smoothly after the pressure filtration is completed.

[0059] It should be noted that, in the process of using the clamping plate 34 to compress the plurality of diaphragm plates 35 to form a closed filter chamber, as the two adjacent diaphragm plates 35 gradually approach each other, the push cylinders 358 on the opposite sides will be in contact first, and as the cylinder 1 33 continues to act, the two push cylinders 358 in contact will push the corresponding straight spring 1 359 to be compressed, so that the push cylinder 358 is completely hidden inside the corresponding perforation. At this time, the straight spring 1 359 is at the maximum compression limit, and the movement of the push cylinder 358 will synchronously drive the corresponding movable frame 355 to move in the direction of the bracket 352 inside the diaphragm plate 35, and the sleeve 1 353 and the sleeve 2 354 inside the same diaphragm plate 35 will move towards each other. In addition, in the process of forming a closed filter chamber, the clamping plate 34 and the thrust plate 32 will squeeze the adjacent diaphragm plates, so that the corresponding push cylinder 358 is completely hidden inside the perforation.

[0060] At this time, a drainage channel connected to the corresponding through hole is formed between the thrust plate 32, the diaphragm plate 35 and the pressing plate 34 after being compressed, wherein the cavity formed between the thrust plate 32, the pressing plate 34 and the corresponding diaphragm plate 35 will not be filled with mud, that is, after the multiple diaphragm plates 35 are compressed by the pressing plate 34, the discharge end of the feed pipe 37 and the sleeve 1 353 on the corresponding diaphragm plate 35 are in a pressed state to form a passage, and at the same time, the discharge end of the recoil pipe 38 and the sleeve 2 354 on the corresponding diaphragm plate 35 are in a pressed state to form a passage;

[0061] When the filtration is completed, as the thrust plate 32, the diaphragm plate 35 and the clamping plate 34 are completely separated, the two movable frames 355 on the diaphragm plate 35 will move in opposite directions under the action of the corresponding straight spring 359, thereby pushing the filter cake inside the filter chamber out and allowing the filter cake to fall out of the filter chamber under the action of its own gravity.

[0062] Specifically, Figure 4 As shown, the opening and closing assembly 36 includes an L-shaped frame 361 fixedly installed on both sides of the square frame 351 by locking bolts. This detachable design is matched with the mounting seat 31 and the detachable design between the thrust plate 32 and the U-shaped main beam, so that a single diaphragm plate 35 can be quickly replaced, which is convenient for operation and maintenance. The two L-shaped frames 361 are movably hung on the corresponding U-shaped main beam, and grooves 362 are provided on both sides of the L-shaped frame 361. The inner top and bottom of the two grooves 362 are provided with sink grooves. A connecting column 363 is fixedly provided on the middle part of the top of the L-shaped frame 361, and two swing bars 364 are rotatably installed on the outer side of one end of the connecting column 363. The two ends of the two swing bars 364 extend to the corresponding grooves 362. One end is fixed with a cylinder slidably connected between the two sink grooves. In the process of the two swing bars 364 swinging with the corresponding connecting column 363 as the central axis, the two swing bars 364 are always arranged in an X-shaped structure.

[0063] It should be noted that when two adjacent diaphragm plates 35 are in the process of opening and closing, the two swing bars 364 will swing around the corresponding connecting column 363 as the central axis, that is, the two ends of the swing bars 364 extending to the inside of the same groove 362 will move toward or away from each other along the sink groove. By arranging an opening and closing assembly between two adjacent diaphragm plates 35, multiple diaphragm plates 35 can be opened and closed in one step.

[0064] Specifically, Figure 1-2 and Figure 9-10 As shown, a pull-back mechanism 6 is provided at one end of the outer side of the two U-shaped main beams near the mounting seat 31. The pull-back mechanism 6 includes a second cylinder 61 fixed on the outer side of the U-shaped main beam and a T-shaped slot 63 opened on the outer side of the U-shaped main beam. A seat block 62 is fixedly connected to the telescopic end of the second cylinder 61. A T-shaped block 64 slidably connected to the inside of the T-shaped slot 63 is fixedly provided on the outer side of the seat block 62. The seat block 62 performs linear motion under the action of the second cylinder 61 by utilizing the matching restriction of the T-shaped slot 63 and the T-shaped block 64, thereby reducing the stress on the telescopic end of the second cylinder 61 when the closed diaphragm plate 35 is pulled open by the pull-back mechanism 6.

[0065] A swing groove 65 is formed in the middle of the seat block 62, and a swing plate 66 is rotatably mounted in the middle of the swing groove 65 through a rotating rod. An arc rod 67 that movably penetrates the bottom end of the swing plate 66 is fixedly connected to the inner side of one end of the swing groove 65, and an arc spring 68 that is fixedly connected to the swing plate 66 and the inner wall of the swing groove 65 is sleeved on the outer side of the arc rod 67. When the arc spring 68 is in a natural state, the swing plate 66 is just in a state as shown in FIG. Fig.10 In the vertical state shown in the figure, at this time, one end of the arc rod 67 still remains in a state of moving through the bottom end of the swing plate 66.

[0066] It should be noted that during the initial installation of the membrane filter, there will be no intersection between the pullback mechanism 6 and the diaphragm plate 35 close to the clamping plate 34, that is, during the process of unloading the filter cake, it is necessary to use cylinder 2 61 to push the seat block 62 toward the adjacent diaphragm plate 35, and use the reverse thrust of the diaphragm plate 35 to make the swing plate 66 swing, and compress the arc spring 68 along the direction of the arc rod 67. After the swing plate 66 passes over the diaphragm plate 35 and resets, the seat block 62 is pulled back by cylinder 2 61, and the diaphragm plate 35 after clamping is pulled open by the vertical swing plate 66. In each subsequent clamping process, cylinder 1 33 and cylinder 2 61 will undergo synchronous elongation changes to prevent the pullback mechanism 6 from affecting the clamping process. Accordingly, during the decompression and unloading process, cylinder 1 33 and cylinder 2 61 will retract successively.

[0067] Specifically, Figure 2 and Figure 8As shown, a fastening mechanism 8 is provided between the thrust plate 32 and the adjacent frame 351, wherein the fastening mechanism 8 is arranged into two groups, an upper group and a lower group, which can improve the stability of fastening the corresponding diaphragm plate 35, and the fastening mechanism 8 includes two supports 81 fixed on the top of the thrust plate 32 and a fastening groove 84 opened on the top of the corresponding frame 351, and a deflection buckle plate 82 is rotatably installed between the two supports 81 by a rotating rod, and a straight spring three 83 is fixedly connected between the deflection buckle plate 82 and the thrust plate 32.

[0068] It should be noted that during the initial installation of the diaphragm filter, when the fastening mechanism 8 is used to clamp the diaphragm plate 35 adjacent to the thrust plate 32, the tensile restoring force of the straight spring 3 83 is used to pull the fastening end of the deflection buckle plate 82 toward the thrust plate 32, so that the fastening end of the deflection buckle plate 82 is tightly fastened to the fastening groove 84 on the corresponding diaphragm plate 35, and, after the corresponding diaphragm plate 35 is fastened by the fastening mechanism 8, the side of the frame 351 facing the thrust plate 32 is in a tight fit with the thrust plate 32.

[0069] Specifically, Figure 1-2 and Figure 4 As shown, the water washing mechanism 4 is composed of a central water inlet assembly and a side water inlet assembly, and is used to quickly and fully wash the kaolin to be treated inside the upper filter chamber of the filter press mechanism 3 by coordinating the side water supply with the central water supply;

[0070] The central water inlet assembly includes a second water inlet pipe 42 connected to the feed pipe 37, and a second control valve is installed on the second water inlet pipe 42 and the feed pipe 37. When feeding, the second control valve on the second water inlet pipe 42 is in a closed state, and the second control valve on the feed pipe 37 is in an open state. On the contrary, when water is passed for flushing, the second control valve on the feed pipe 37 is in a closed state, and the second control valve on the second water inlet pipe 42 is in an open state.

[0071] The side water inlet assembly includes a water inlet pipe 41 fixed between the T-shaped plate 9 and the straight plate 10, and a water supply pipe is provided on the outside of the water inlet pipe 41 corresponding to the position of each box 351 and the middle part of the outside of each box 351, and a control valve 3 is installed on the water supply pipe on the outside of each box 351, and a water inlet hose 43 is provided between the two corresponding water supply pipes.

[0072] It should be noted that, in the process of cleaning the sludge inside the filter chamber, water is supplied synchronously through the water inlet pipe 2 42 and the water inlet pipe 1 41, that is, the water supplied by the water inlet pipe 2 42 flows into each filter chamber from the sludge inlet channel, and is cleaned in a diffuse manner from the center to the surroundings, while the water supplied by the water inlet pipe 1 41 enters the diaphragm cavity (i.e., the cavity formed between the two diaphragms 3510 on the diaphragm plate 35) on both sides of the corresponding filter chamber through the water inlet hose 43, and water is supplied to the filter chamber on both sides of the diaphragm cavity for cleaning, wherein the water supplied at the side and the water supplied at the center will form a backwash inside the filter chamber, thereby improving the cleaning effect;

[0073] Further, in the process of cleaning the sludge inside the filter chamber, when the sludge is injected into the filter chamber through the feed pipe 37, the control valve 1 on the backwash pipe 38 is in a closed state. After the sludge injection is completed, the control valve 1 on the backwash pipe 38 will be opened, and the sludge inside the mud injection channel will be backwashed into the sludge pool by water flow for standby use. When the sludge inside the mud injection channel is cleaned, the control valve 2 on the feed pipe 37 and the control valve 1 on the backwash pipe 38 are closed to keep the inside of the mud injection channel in a water-retaining state. Then, the control valve 2 on the water inlet pipe 2 42 and the control valve 3 on the water supply pipe are opened. At the same time, the control valve 1 on the backwash pipe 38 is kept closed to realize the combination of central water injection and side water injection to clean the sludge inside the filter chamber. In the process of cleaning the sludge, the control valve 1 on the drain pipe 39 will be opened, and the sewage generated by the cleaning will enter the drainage channel through the gap between the adjacent diaphragm plates 35, and enter the confluence cavity through the through hole on the pressing plate 34, and finally be discharged through the drain pipe 39.

[0074] Compared with the traditional diaphragm filter press, the design of the water washing mechanism 4 adds a central water inlet, which is used in conjunction with the traditional side water inlet to clean the sludge inside the filter chamber, thereby improving not only the cleaning efficiency but also the cleaning effect.

[0075] Specifically, Figure 1-2 and Figure 4-5 As shown, the air supply mechanism 5 is composed of a decontamination component for removing residual sewage inside the drainage channel and a water pressing component for squeezing and dehydrating kaolin inside the upper filter chamber of the filter press mechanism 3;

[0076] The water squeezing assembly includes an air intake main pipe 51 fixedly arranged between the T-shaped plate 9 and the straight plate 10, and an air supply pipe is connected to the position of each square frame 351 on the outside of the air intake main pipe 51 and the middle part of the outside of each square frame 351, and a control valve 4 is installed on the air supply pipe on the outside of each square frame 351, wherein one end of the air intake branch pipe 1 3511 away from the corresponding box 351 is connected to the air supply pipe on the box 351, and an air intake hose 55 is connected between the two corresponding air supply pipes;

[0077] The decontamination assembly includes a vent pipe 52 fixed on the thrust plate 32 corresponding to the through hole and a hollow square ring 53 connected to the four vent pipes 52. A control valve five is installed on each of the four vent pipes 52. An intake branch pipe two 54 is provided between the hollow square ring 53 and the intake main pipe 51.

[0078] It should be noted that after the sludge inside the filter chamber is cleaned, the control valve 2 on the water inlet pipe 2 42 and the control valve 3 on the water supply pipe are closed. At the same time, the control valve 4 on the air supply pipe is opened, and the control valve 6 on the corresponding air inlet branch pipe 1 3511 is closed, so that the high-pressure gas inside the air inlet main pipe 51 can continue to enter the cavity between the two diaphragms 3510 inside the frame 351 through the air inlet hose 55, and the bulging diaphragm cavity is used to squeeze the cleaning residues inside the filter chambers on both sides, so that the squeezed water is discharged through the drainage channel. When the squeezing is completed, the control valve 5 on the four ventilation pipes 52 is opened, and the high-pressure gas inside the air inlet main pipe 51 is introduced into the ventilation pipe 52 by using the connected air inlet branch pipe 2 54 and the hollow square ring 53, and the residual sewage in the drainage channel is emptied into the confluence cavity for discharge with the help of the introduced high-pressure gas;

[0079] In addition, in the process of using the compression plate 34 to compress the multiple diaphragm plates 35 to form a closed filter chamber, when the compression is completed, it is necessary to open the control valve six on the intake branch pipe 3511, and at the same time, close the control valve four on the corresponding air supply pipe, so that the high-pressure gas inside the intake main pipe 51 enters the corresponding air bag 3512 through the intake hose 55 and the intake branch pipe 3511, and after the inflated air bag 3512 fills the concave cavity formed between the movable frame 355 and the corresponding side inside the square ring groove, close the control valve six to keep the air bag 3512 in a pressure-maintaining state. Only after the water squeezing is completed and the multiple diaphragm plates 35 are completely pulled apart, will the control valve six on the intake branch pipe 3511 be closed, and the compression recovery force of the straight spring 359 be used to squeeze the corresponding movable frame 355, so that the corresponding air bag 3512 is deflated and the filter cake is pushed out simultaneously.

[0080] In summary, the overall working process of the filter press part of the high-pressure diaphragm filter can be summarized as: press the diaphragm plate 35 → inject sludge into the filter chamber → backwash to remove excess sludge inside the sludge injection channel → double-sided water injection to fully flush the sludge → squeeze out the water in the cleaning residue in the filter chamber → discharge the residual sewage inside the drainage channel → pull open the diaphragm plate 35 to discharge the filter cake.

[0081] Example 2

[0082] Refer to the instruction manual Figure 1 and Figure 11-12 In a kaolin high-pressure membrane filter according to an embodiment of the present invention, the filter cake processing mechanism 7 is composed of a material pressing component for extruding the fallen filter cake and a material conveying component for conveying the formed material block;

[0083] The material pressing assembly includes a through groove opened on the top of the mounting platform 1 and an F-shaped seat 71 fixed on the top of the mounting platform 1 in the middle of both sides of the through groove. A material receiving frame 72 and a hollow cylinder 73 arranged from top to bottom are fixedly connected between the two F-shaped seats 71. The bottom end of the material receiving frame 72 contacts the outside of the hollow cylinder 73, and the bottom end of the material receiving frame 72 and the outside of the hollow cylinder 73 are penetrated by leakage grooves. The three leakage grooves are arranged vertically in a collinear manner. Among them, the material receiving frame 72 is arranged in a V-shaped structure, which can guide the falling filter cake to approach the corresponding leakage groove.

[0084] L-shaped plates 74 are fixedly connected to the middle of both sides of the material receiving frame 72. An annular rotating cylinder 78 is movably sleeved inside the hollow cylinder 73. A plurality of brackets evenly distributed in annular shapes are provided on the outside of the annular rotating cylinder 78. A motor 1 is fixedly installed on the outside of one of the L-shaped plates 74. The end of the output shaft of the motor 1 extends to the inside of the hollow cylinder 73 and is fixedly connected to the annular rotating cylinder 78. A motor 2 is fixedly installed on the inside of the other L-shaped plate 74. The end of the output shaft of the motor 2 is fixedly connected to a cam strip 712 extending to the inside of the annular rotating cylinder 78.

[0085] A material guide frame 75 is fixedly provided in the middle part of the inner side of the material receiving frame 72, and a cylinder three 76 is fixedly installed in the inner side of the material guide frame 75. The telescopic end of the cylinder three 76 is fixedly connected with a pressure strip 77, wherein the material guide frame 75 is arranged as an inverted V-shaped structure, which is used to cooperate with the material receiving frame 72 of the V-shaped structure to guide the fallen filter cake to approach the block forming area, and the width of the pressure strip 77 is equal to the width of the slot of the leakage groove, and the bottom end surface of the pressure strip 77 is arranged in an arc, and an arc strip 79 is movably embedded in the middle part of the inner side of each bracket, and a push strip 710 that movably passes through the annular rotating drum 78 is provided at a position corresponding to the middle part of each bracket inside the annular rotating drum 78, and the push strip 710 extends to one end of the corresponding bracket and is fixedly connected to the arc strip 79, and a straight spring two 711 is fixedly connected between the two ends of each push strip 710 and the inner wall of the annular rotating drum 78, wherein, when the straight spring two 711 is in a natural state, the arc strip 79 is in a state as follows under the action of the straight spring two 711 Fig.12 The status shown;

[0086] The feeding assembly includes a feeding belt 713 fixedly mounted on the bottom of the mounting platform 1, and a plurality of equally spaced support plates 714 are arranged on the outside of the feeding belt 713, wherein the feeding belt 713 is a step-by-step transmission, and each time a single-pass transmission is completed, there is a support plate 714 facing the corresponding leakage groove, and buffer springs are fixedly connected between the two ends of each support plate 714 on one side facing the feeding belt 713 and the feeding belt 713.

[0087] It should be noted that, in the process of handling the filter cake that falls off after the filtration is completed, the filter cake that falls into the receiving frame 72 will become loose under the impact of the fall, and the loose filter cake will approach the corresponding leakage groove under the cooperation of the guide frame 75 and the receiving frame 72. Whenever the annular drum 78 rotates until one of the brackets is aligned with the leakage groove at the bottom of the receiving frame 72, the loose filter cake will automatically slide into the bracket, and then the cylinder three 76 will push the pressure bar 77 to move downward to compact and shape the loose filter cake gathered at the bracket position. After completing a round of compaction and molding, the annular drum 78 will rotate 90° (herein, Fig.12 The four brackets shown are used as an example for explanation), and at the same time, the cam bar 712 rotates one circle under the action of the motor 2;

[0088] During the process of the cam strip 712 rotating one circle, the cam strip 712 will perform one round of squeezing on the push strip 710 at the position of the leakage groove facing the bottom end of the hollow cylinder 73, so that the corresponding straight spring 2 711 will be compressed and deformed once, so as to use the push strip 710 to push out the corresponding arc strip 79. If there is no compacted filter cake inside the bracket at this position, the arc strip 79 will be empty. Otherwise, the arc strip 79 will push out the compacted filter cake inside the bracket at this position, so that it falls on the support plate 714, and the buffer spring will be used for buffering to prevent the compacted filter cake from loosening again.

[0089] The design of the filter cake handling mechanism can not only avoid the problem of space occupation during the transportation of loose filter cakes, but also the compacted filter cakes can be conveniently stacked for centralized transportation, thereby improving the single transportation volume and transportation efficiency of the filter cakes.

[0090] In the above technical solution, the cylinder mentioned is a single-acting cylinder of model DSA25N200; the motor mentioned is a stepping servo motor of model PK268M-01A.
