Description

Technical Field

[0001] The present application relates to the manufacturing technology of driving devices, and in particular to a stacked bag filter press. Background Art

[0002] A filter press is a mechanical device that effectively separates solid particles from liquid in a suspension by applying an external pressure, and is widely used in industries such as mining, chemical industry, pharmaceutical industry, metallurgy, food, and environmental protection.

[0003] In the solutions of related technologies, a filter press forms a filter chamber after two opposite filter plates are abutted. Specifically, a groove is provided in the filter plate, a filter cloth is provided in the groove, and the grooves on the two filter plates are arranged oppositely, so as to form a filter chamber after abutment. An inlet is also provided in the middle of the pressure filtration surface of the filter plate (i.e., the surface that abuts against the adjacent filter plate or driving device during pressure filtration). Two adjacent filter chambers on the filter press are connected through their respective inlets, and the filter chamber at the end is connected to the inlet pipe through the inlet. When the filter press is feeding, the material to be filtered enters each filter chamber in sequence from the inlet pipe.

[0004] However, in the solutions of related technologies, since the material to be filtered fills the filter chambers in sequence, when there are many filter chambers, the feeding time difference between the first filter chamber and the last filter chamber is relatively large, and the feeding consistency of each filter chamber cannot be guaranteed, resulting in differences in the moisture content, thickness, etc. of the subsequent filter cakes.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application.

[0060] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0061] As described in the background technology, in the scheme of the related technology, when the filter press is fed, the material to be filtered enters each filter chamber in turn from the feed pipe. Therefore, when there are many filter chambers, the feeding time difference between the first filter chamber and the last filter chamber is large, and the feeding consistency of each filter chamber cannot be guaranteed, resulting in differences in the moisture content, thickness, etc. of the subsequent filter cakes.

[0062] In view of this, an embodiment of the present application aims to provide a stacked bag filter press, in which filter bags and plate-shaped drainage boards are arranged, the filter bags are arranged between two adjacent drainage boards, and the first elastic blocks on the two adjacent drainage boards are abutted against the filter bags to seal the discharge port of the filter bags, thereby ensuring the sealing of the discharge port; when feeding, the main feed pipe can simultaneously add the material to be filtered into multiple filter bags through multiple feed branch pipes, so that the feeding time of each filter bag is roughly consistent, which is beneficial to ensure the consistency of the moisture content, thickness, etc. of the subsequent filter cakes.

[0063] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail. It should be noted that in the description of the present embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in a three-dimensional space, and the first direction X, the second direction Y, and the third direction Z can be perpendicular to each other, and the third direction Z can be, for example, a vertical direction.

[0064] Please refer to Figures 1 - 8 This embodiment provides a bag filter press, comprising:

[0065] The rack 100 includes two side panels 110 arranged opposite to each other along a first direction X. The side panels 110 can be fixed on the ground by legs or the like. The two side panels 110 provide a basis for the installation of other parts.

[0066] A plurality of drain plates 200 are provided, and the drain plates 200 are generally plate-shaped. The plurality of drain plates 200 are slidably arranged between the two side plates 110, and the plurality of drain plates 200 are arranged at intervals along the second direction Y. A first elastic block 210 is provided on both sides of the drain plates 200 along the second direction Y, and the first elastic block 210 is close to the first end of the drain plates 200 along the third direction Z. Exemplarily, the drain plates 200 can be made of a metal material so that they have a stronger hardness. The first elastic block 210 includes any one of a polyurethane block or a rubber block, and the hardness of the first elastic block 210 can be adjusted as needed. The connection method between the first elastic block 210 and the drain plates 200 can be determined as needed.

[0067] The filter bag 300 is disposed between two adjacent drainage plates 200 and is connected to the drainage plates 200. Exemplarily, the filter bag 300 can be sewn from high-strength filter cloth so that the filter bag 300 can withstand strong pressure without bursting. The specific material of the filter bag 300 can be determined based on requirements. A cavity (i.e., a filter chamber) is formed inside the filter bag 300 to facilitate injecting the material to be filtered into the filter bag 300. That is to say, the filter chamber in this embodiment is completely surrounded by the filter bag 300, and the drainage plate 200 only serves to press-filter and drain water, without forming a filter chamber by abutting the drainage plate 200, thus simplifying the structure of the drainage plate 200. A discharge port (not shown in the figure) is provided at the first end of the filter bag 300 along the third direction Z (i.e., the bottom surface of the filter bag). Two adjacent first elastic blocks 210 can respectively abut against both sides of the filter bag 300 along the second direction Y to seal the discharge port. An inlet port 310 is also provided on the filter bag 300. Exemplarily, it can be connected to the cavity inside the filter bag 300 through an inlet pipe, and the inlet port is formed at one end of the inlet pipe facing away from the filter bag 300.

[0068] In this embodiment, two or more filter bags 300 can be disposed between two adjacent drainage plates 200. When multiple filter bags 300 are provided, since the filter bag 300 itself is made of a flexible material, even when the distance between two adjacent drainage plates 200 is fixed, the size of the filter bag 300 is not fixed. In the case of abnormal feeding and individual filter bags 300 not being filled, adjacent filter bags 300 can complement each other to a certain extent, reducing the impact of abnormal feeding on the overall machine life.

[0069] "Stacked bags" in the stacked bag filter press of this embodiment means that the filter chamber on the filter press is completely formed by the filter bag 300 itself, and the drainage plate 200 only serves to press-filter and drain water without forming a filter chamber. One or more filter bags 300 can be disposed between two adjacent drainage plates 200 to form one or more filter chambers.

[0070] Feeding device 400, a feeding device 400 is provided on at least one side of the frame 100 along the first direction X. The feeding device 400 includes a main feeding pipe 410 and a plurality of feeding branch pipes 420 communicating with the main feeding pipe 410. The plurality of feeding branch pipes 420 are respectively connected to a plurality of feeding ports 310, that is, each feeding branch pipe communicates with one filter bag 300. During feeding, the main feeding pipe 410 is used to simultaneously inject the material to be filtered into a plurality of filter bags 300 through the plurality of feeding branch pipes 420, so as to ensure that the feeding time of the plurality of filter bags 300 is generally the same. Exemplarily, the main feeding pipe 410 of the present embodiment can be a rigid pipe, and the feeding branch pipes 420 can be flexible pipes. The main feeding pipe 410 can be connected to the plurality of feeding branch pipes 420 through devices such as a feeding controller 430, so as to control the amount of the material to be filtered entering each feeding branch pipe 420. A control valve 440 can be provided between the feeding branch pipe 420 and the feeding controller 430 to control the opening or closing of the feeding branch pipe 420.

[0071] Driving device 500, the driving device 500 is located on one side of the frame 100 along the second direction Y. The driving device 500 is used to drive the drainage plate 200 to move along the second direction Y to perform pressure filtration on the filter bag 300. Exemplarily, the driving device 500 can include, for example, a hydraulic cylinder or a pneumatic cylinder, etc. The driving device 500 pushes the pressing plate to move along the second direction Y through the hydraulic cylinder or the pneumatic cylinder, so as to realize the pressure filtration of a plurality of filter bags 300.

[0072] In this embodiment, by arranging the filter bag 300 between two adjacent drainage plates 200, a filter chamber is formed by the filter bag 300 itself. The first elastic blocks 210 on the two adjacent drainage plates 200 are abutted against the filter bag 300 to seal the discharge port of the filter bag 300, so as to ensure the sealing performance of the discharge port. During feeding, the main feeding pipe 410 can simultaneously inject the material to be filtered into a plurality of filter bags 300 through the plurality of feeding branch pipes 420, so that the feeding time of each filter bag 300 is generally the same, which is beneficial to ensuring the consistency of the moisture content, thickness, etc. of the subsequent filter cake.

[0073] In this embodiment, the feeding port 310 can be arranged on at least one side of the filter bag 300 along the first direction X. Alternatively, the feeding port 310 can be arranged at the second end of the filter bag 300 along the third direction Z (i.e., the top surface of the filter bag 300). The specific setting position of the feeding port 310 can be determined based on needs.

[0074] Preferably, as Figure 2 shown, in this embodiment, feeding ports 310 are provided on both sides of the filter bag 300 along the first direction X. Thus, the material to be filtered can be simultaneously injected into the filter bag 300 through the feeding devices 400 on both sides, which is beneficial to ensuring the uniformity of feeding of the filter bag 300.

[0075] In this embodiment, water distributors 250 are provided on both sides of the drainage plate 200 along the first direction X. The lower end of the water distributor 250 can be connected to the incoming material branch pipe 420, and the upper end of the water distributor 250 is communicated with the incoming material port 310 through a step nipple or the like.

[0076] Please continue to refer to Figure 1 and Figure 3 In this embodiment, handles 220 are provided on both sides of the drainage plate 200 along the first direction X. Sliders 221 are provided on the handles 220, and the sliders 221 can be fixedly connected to the handles 220 through fasteners such as bolts. First slide rails 120 are provided on both side plates 110, and the first slide rails 120 can be provided on the top surface of the side plates 110 along the third direction Z. The drainage plate 200 is slidably arranged on the first slide rails 120 on both sides through the sliders 221 on both sides. During processes such as pressure filtration, the drainage plate 200 can move along the second direction Y under the action of an external force.

[0077] Please continue to refer to Figure 3 、 Figure 4 and Figure 5 On the second end of the drainage plate 200 along the third direction Z (i.e., the top surface of the drainage plate 200) in this embodiment, a filter bag hanging rack 230 is provided. At least one hanging rod 231 is provided on both sides of the filter bag hanging rack 230 along the second direction Y. On the second end of the filter bag 300 along the third direction Z (i.e., the top surface of the filter bag 300), a hanging ear 320 is provided, and the hanging ear 320 is sleeved on the hanging rod 231.

[0078] Exemplarily, two hanging rods 231 are provided on both sides of the filter bag hanging rack 230 along the second direction Y in this embodiment, and two corresponding hanging ears 320 are provided on the filter bag 300. The filter bag 300 is hung on the two hanging rods 231 on the same side through the two hanging ears 320. Both sides of the drainage plate 200 along the second direction Y can be simultaneously connected to the filter bag 300 through the hanging rods 231 on both sides. It can be understood that the hanging rods 231 on the same side can simultaneously connect multiple filter bags 300.

[0079] Please continue to refer to Figure 3 In this embodiment, first installation grooves are provided on both sides of the drainage plate 200 along the second direction Y. The first installation grooves are close to the first end of the drainage plate 200 along the third direction Z, and the first elastic blocks 210 are in interference fit with the first installation grooves. Specifically, the first installation grooves can be dovetail grooves for example, and part of the first elastic blocks 210 are pressed into the dovetail grooves, thereby realizing the interference fit with the drainage plate 200.

[0080] As Figure 3As shown, on both sides of the drainage plate 200 of this embodiment along the second direction Y, there are also provided second elastic blocks 240. The second elastic blocks 240 extend along the third direction Z, and two adjacent second elastic blocks 240 can respectively abut against both sides of the filter bag 300 along the second direction Y. Optionally, the second elastic block 240 includes any one of a polyurethane block or a rubber block, and the hardness of the second elastic block 240 can be adjusted as needed.

[0081] During the pressure filtration process of this embodiment, the second elastic blocks 240 on two adjacent drainage plates 200 can respectively abut against both sides of the filter bag 300, thereby dividing the cavity into multiple continuous sub-cavities. In this embodiment, the second elastic block 240 can be made of a material with an elastic modulus smaller than that of the filter bag 300. During pressure filtration, the second elastic block 240 can absorb part of the deformation amount of the filter cake and reduce the extrusion of the filter cake on the filter bag 300. After the filter bag 300 is extruded by the second elastic blocks 240 on both sides, the filter cake inside it deforms accordingly, forming a region with a relatively thin local thickness. It can be understood that this region is located between two adjacent sub-cavities. Since the thickness of this region is relatively thin, it is also easier to break during subsequent vibration, thereby reducing the probability of the filter cake adhering to the inside of the filter bag 300 and improving the safety of using the stacked bag pressure filter.

[0082] Furthermore, at least one groove 241 is formed at one end of the second elastic block 240 facing away from the drainage plate 200. The groove 241 can enable the filtrate to flow between the sub-cavities on both sides of the second elastic block 240, so that the pressures in adjacent sub-cavities are the same. In addition, the second elastic block 240 functions to divide the filter cake. When used in cooperation with the vibration device 600, the filter cake is prone to break here during unloading, so as to reduce the unloading difficulty of the filter bag 300.

[0083] In this embodiment, on both sides of the drainage plate 200 along the second direction Y, there are provided second installation grooves. The second installation grooves extend along the third direction Z, and the second elastic blocks 240 are in interference fit with the second installation grooves. Specifically, the second installation groove can be a dovetail groove, for example. Part of the second elastic block 240 is pressed into the dovetail groove, thereby achieving an interference fit with the drainage plate 200.

[0084] In this embodiment, drainage partition nets are provided on both sides of the drainage plate 200 along the second direction Y. The drainage partition nets are used for discharging the liquid generated after the drainage plate 200 pressure-filters the filter bag 300. Exemplarily, the drainage partition net can be formed by a wire mesh provided on the drainage plate 200. Along the third direction Z, one end of the drainage partition net can be fixedly connected to the filter bag 300, and the other end of the drainage partition net can be clamped and fixed by the first elastic blocks 210 on two adjacent drainage plates 200. During the pressure filtration operation, the drainage partition net is in a tensioned state.

[0085] Please continue to refer to Figure 1 andFigure 6 In this embodiment, the bag stacking filter press further includes a vibration device 600. A second track 130 is provided on the side plate 110. The vibration device 600 can slide along the second track 130, and the vibration device 600 is used to separate the filter bag 300 from the filter cake therein after the filtration is completed.

[0086] In this embodiment, the vibration device 600 includes two track trolley mechanisms 610. Second tracks 130 are provided on both side plates 110, and the two track trolley mechanisms 610 are respectively slidably arranged on the two second tracks 130. The vibration device 600 slides along the second direction Y on the frame 100 through the track trolley mechanisms 610 on both sides.

[0087] Further, the vibration device 600 includes a vibration jaw 640 for clamping or releasing the filter bag 300, and a power mechanism 630 for lifting the clamped filter bag 300 by a preset height. When performing the vibration operation, the vibration jaw 640 can clamp the filter bag 300 from the drainage plate 200. After being lifted by the preset height under the drive of the power mechanism 630, the vibration jaw 640 releases the filter bag 300, causing the filter bag 300 to fall onto the frame 100. The impact force during the fall generates a frictional force between the filter cake in the filter bag 300 and the filter bag 300, so as to complete the discharging.

[0088] In this embodiment, the vibration device 600 further includes a gantry 620. The two ends of the gantry 620 are respectively connected to the two track trolley mechanisms 610. The power mechanism 630 and the vibration jaw 640 are both arranged on the gantry 620. The power mechanism 630 is used to drive the vibration jaw 640 to move along the third direction Z, so that the vibration jaw 640 can clamp or release the filter bag 300.

[0089] Specifically, the two ends of the gantry 620 along the first direction X are respectively connected to the two track trolley mechanisms 610. When the track trolley mechanism 610 slides along the second track 130, it can drive the gantry 620 to move synchronously. The gantry 620 provides an installation basis for the power mechanism 630 and the vibration jaw 640. Exemplarily, the power mechanism 630 can include a hydraulic cylinder or a pneumatic cylinder, etc. When the power mechanism 630 drives the vibration jaw 640 to move along the third direction Z, the vibration jaw 640 can open or close, so as to clamp or release the filter bag 300.

[0090] The rapping device 600 of this embodiment further includes a jaw connecting rod 650, and the rapping jaws 640 are arranged on one side of the jaw connecting rod 650 facing the filter bag 300. Power mechanisms 630 are provided on both sides of the gantry 620 along the first direction X, and the output ends of the two power mechanisms 630 are respectively connected to both ends of the jaw connecting rod 650. The power mechanism 630 is used to drive the jaw connecting rod 650 to move along the third direction Z. That is to say, in this embodiment, the telescoping of the power mechanisms 630 on both sides can drive the jaw connecting rod 650 to move along the third direction Z. When the jaw connecting rod 650 moves along the third direction Z, it can synchronously drive the rapping jaws 640 thereon to move along the third direction Z, so that the rapping jaws 640 can clamp or release the filter bag 300.

[0091] Please refer to Figure 3 、 Figure 4 、 Figure 7 and Figure 8 , further, a filter bag hanging rack 230 is provided at the second end of the drainage board 200 along the third direction Z. The filter bag hanging rack 230 is detachably arranged on the drainage board 200, and the filter bag 300 is located on at least one side of the filter bag hanging rack 230 along the second direction Y. Exemplarily, the filter bag hanging rack 230 can be plugged into the drainage board 200, for example. When the power mechanism 630 drives the jaw connecting rod 650 to move towards the filter bag hanging rack 230, the rapping jaws 640 can abut against the filter bag hanging rack 230, so that the rapping jaws 640 open and clamp the filter bag hanging rack 230, thereby clamping the filter bag hanging rack 230 together with the filter bags 300 on both sides thereof and driving it to rise along the third direction Z.

[0092] In this embodiment, a clamping trigger is provided on the filter bag hanging rack 230, and a release trigger is provided on the gantry. When the rapping jaws 640 move along the third direction Z and contact the clamping trigger, the rapping jaws 640 open and clamp the filter bag hanging rack 230. When the rapping jaws 640 move along the third direction Z and contact the release trigger, the rapping jaws 640 release the filter bag hanging rack 230.

[0093] Specifically, as Figure 7 shown, the rapping jaws 640 include two jaw blocks 641 arranged opposite to each other along the second direction Y, two shielding plates 642 arranged opposite to each other along the first direction X, and a connecting plate 643. The two shielding plates 642 are respectively located on both sides of the jaw block 641. The jaw block 641 is rotatably connected to the shielding plate 642, and when the two jaw blocks 641 rotate relative to the shielding plate 642, they can open or close. The connecting plate 643 connects the two shielding plates 642 and the jaw connecting rod 650. The connecting plate 643 can be connected to the shielding plate 642 and the jaw connecting rod 650 through fasteners such as bolts, so as to fix the rapping jaws 640 to the jaw connecting rod 650.

[0094] The rapping jaw 640 moves along the third direction Z to contact the clamping trigger, and the claw block 641 can rotate relative to the baffle plate 642 to open the rapping jaw 640 and clamp the filter bag hanger 230. The rapping jaw 640 moves along the third direction Z to contact the release trigger, and the claw block 641 can rotate relative to the baffle plate 642 to release the filter bag hanger 230.

[0095] like Figure 8 As shown, the claw block 641 includes a hinge portion 6411 and a first claw rod 6412, a second claw rod 6413 and a third claw rod 6414 connected to the hinge portion 6411. The hinge portion 6411 is hinged to the shielding plate 642; for example, the hinge can be realized by parts such as a pin shaft.

[0096] The first claw rod 6412 is connected to the first end of the hinge part 6411 along the third direction Z. The first claw rod 6412 is formed with a first abutting portion 64121 at one end away from the hinge part 6411. The first abutting portion 64121 is arranged toward the other claw block 641, and the size of the first abutting portion 64121 along the second direction Y gradually decreases in the direction away from the hinge part 6411. In other words, the first abutting portion 64121 has an inclined surface arranged toward the other claw block 641.

[0097] The second claw rod 6413 is connected to the second end of the hinge part 6411 along the third direction Z, and the second claw rod 6413 includes a first section 64131 and a second section 64132 connected to each other. The first section 64131 is connected to the hinge part 6411 and extends toward a side away from the other claw block 641 in the second direction Y. The second section 64132 is connected to the first section 64131 and extends toward a side of the other claw block 641 in the second direction Y. In other words, the second section 64132 has an inclined surface disposed away from the other claw block 641.

[0098] The third claw rod 6414 is connected to one end of the hinge portion 6411 toward the other claw block 641 along the second direction Y. When the rapping jaw 640 is in a free state, the third claw rods 6414 of the two claw blocks 641 abut against each other, thereby maintaining relative balance.

[0099] When the rapping jaw 640 moves along the third direction Z, the first claw rod 6412 is used to abut against the clamping trigger member, so that the rapping jaw 640 opens and clamps the filter bag hanger 230. The second claw rod 6413 is used to abut against the release trigger member, so that the rapping jaw 640 releases the filter bag hanger 230.

[0100] like Figure 4As shown, the filter bag hanger 230 includes a hanger body 232, an adapter plate 233 and a suspension rod 231. The projection of the hanger body 232 in a plane perpendicular to the first direction X is generally in the shape of an "I". The hanger body 232 is connected to the adapter plate 233 on both sides along the second direction Y, and the suspension rod 231 is connected to the adapter plate 233. The clamping trigger member includes an opening trigger block 2321 arranged at the second end of the hanger body 232 along the third direction Z, and the opening trigger block 2321 extends along the second direction Y. When the rapping jaw 640 moves toward the opening trigger block 2321 along the third direction Z, the first claw rods 6412 of the two claw blocks 641 can respectively abut against the two ends of the opening trigger block 2321 along the second direction Y, so that the two first claw rods 6412 are away from each other, thereby opening the rapping jaw 640. After the first claw rod 6412 passes through the opening trigger block 2321, the two first claw rods 6412 can abut against the opening trigger block 2321 to clamp the filter bag hanger 230, and then the filter bag hanger 230 and the filter bag 300 can be driven to rise as a whole through the power mechanism 630.

[0101] like Figure 6 As shown, the release trigger member includes two rapping trigger blocks 621 arranged opposite to each other along the second direction Y. The rapping trigger block 621 includes a connecting section 6211 and a trigger section 6212, and the connecting section 6211 and the trigger section 6212 generally form a "7" shape. The connecting section 6211 is connected to the gantry 620 along the third direction Z, and the trigger section 6212 is located at one end of the connecting section 6211 away from the gantry 620, and the trigger section 6212 extends toward the other rapping trigger block 621.

[0102] When the rapping clamp 640 moves toward the rapping trigger block 621 along the third direction Z, the second claw rods 6413 of the two claw blocks 641 can respectively abut against the two rapping trigger blocks 621, so that the two first claw rods 6412 move away from each other, thereby releasing the filter bag hanger 230. The filter bag hanger 230 falls onto the frame 100 under the action of gravity, thereby separating the filter bag 300 from the filter cake therein.

[0103] Please continue to refer to Figure 8 The rapping jaw 640 of this embodiment also includes an elastic member, and an elastic member mounting seat 644 is provided on the side of the second claw rod 6413 facing the other claw block 641, and the two ends of the elastic member are respectively sleeved on the two elastic member mounting seats 644. When the rapping jaw 640 is in a free state, the two ends of the elastic member respectively apply elastic force to the two second claw rods 6413, and the third claw rods 6414 of the two claw blocks 641 abut against each other, so that the rapping jaw 640 is maintained in a closed state. When the rapping jaw 640 is opened, the elastic member can be compressed, and when the power mechanism 630 drives the jaw connecting rod 650 to pass through the opening trigger block 2321, the elastic restoring force of the elastic member can make the rapping jaw 640 close and clamp the filter bag hanger 230.

[0104] It is understandable that the vibrating device 600 can move along the second direction Y to both sides of any drainage plate 200, and through the above process, the processes of clamping, lifting, and releasing the filter bag hanger 230 are realized, thereby completing vibrating discharging.

[0105] When installing the bag stacking filter press of this embodiment, first hang the filter bags 300 on both sides of the drainage plate 200. It is understandable that one or more filter bags 300 can be arranged between two adjacent drainage plates 200, and the specific number of filter bags 300 to be hung can be set as required. Then, the drainage plates 200 with the filter bags 300 hung can be successively placed on the frame 100, so that the sliders 221 on the handles 220 on both sides of the drainage plate 200 are slidably connected to the first slide rail 120 on the side plate 110. During use, start the driving device 500 to initially squeeze the drainage plate 200 by using the driving device 500, and the two first elastic blocks 210 on the adjacent drainage plates 200 seal the discharging port; start the feeding device 400, and simultaneously inject the substances to be filtered into a plurality of filter bags 300 through a plurality of feeding branch pipes 420 communicating with the main feeding pipe 410, so that the feeding time of each filter bag 300 is generally the same, which is beneficial to ensuring the consistency of the moisture content, thickness, etc. of the subsequent filter cakes. After the feeding is completed, increase the pressure of the driving device 500, and use the driving device 500 to filter press the filter bags 300 between the drainage plates 200 to discharge the excess water in the substances to be filtered in the filter bags 300. After the filter pressing is completed, release the driving device 500, the discharging port of the filter bag 300 is opened, start the vibrating device 600, and move the vibrating device 600 along the second track 130 to the upper part of the filter bag 300 to be unloaded; first open the drainage plate 200 by a certain distance, the power mechanism 630 drives the vibrating clamping jaw 640 to move towards the drainage plate 200, and the vibrating clamping jaw 640 opens after contacting the opening trigger block 2321, and then clamps the filter bag hanger 230 on the drainage plate 200, and clamps the filter bag hanger 230 together with the filter bags 300 on both sides thereof. Subsequently, the power mechanism 630 drives the vibrating clamping jaw 640 to move away from the drainage plate 200, and the vibrating clamping jaw 640 opens and releases the filter bag hanger 230 after contacting the vibrating trigger block 621 on the gantry 620, and the filter bag hanger 230 falls onto the frame 100 under the action of gravity, so that the filter bag 300 is separated from the filter cake therein. The vibrating device 600 moves along the second track 130 to the upper part of the next filter bag 300 to be unloaded, and repeats the above process until all the filter bags 300 are unloaded.
