Description

Technical Field

[0001] This application relates to drive device manufacturing technology, and more particularly to a stacked bag filter press. Background Technology

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

[0003] In related technical solutions, a filter press forms filter chambers by the contact of two opposing filter plates. Specifically, each filter plate has a groove containing a filter cloth, and the grooves on the two filter plates are positioned opposite each other, thus forming a filter chamber upon contact. A feed inlet is also provided in the center of the pressing surface of the filter plate (i.e., the surface that contacts the adjacent filter plate or drive device during filtration). Adjacent filter chambers on the filter press are connected through their respective feed inlets, and filter chambers at the ends are connected to a feed pipe through their feed inlets. During feeding, the material to be filtered enters each filter chamber sequentially from the feed pipe.

[0004] However, with the solution using the relevant technology, since the filter chambers are filled sequentially by the material to be filtered, when there are many filter chambers, the feeding time difference between the first and last filter chambers is large, and the consistency of feeding in each filter chamber cannot be guaranteed, resulting in differences in the moisture content and thickness of the subsequent filter cake. Summary of the Invention

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

[0060] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

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

[0062] In view of this, the present application aims to provide a stacked bag filter press, which sets filter bags and plate-shaped drainage plates, with the filter bags placed between two adjacent drainage plates. The first elastic blocks on the two adjacent drainage plates abut against the filter bags to seal the discharge port of the filter bags, thereby ensuring the sealing of the discharge port. During 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 the same, which is beneficial to ensure the consistency of the moisture content, thickness, etc. of the subsequent filter cake.

[0063] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the content of this application. It should be noted that, in the description of this embodiment, the first direction X, the second direction Y, and the third direction Z are three different directions in three-dimensional space. 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 stacked bag filter press, comprising:

[0065] The frame 100 includes two side plates 110 arranged opposite each other along a first direction X. The side plates 110 can be fixed to the ground by means of support legs, etc. The two side plates 110 provide a foundation for the installation of other parts.

[0066] Multiple drainage boards 200, generally plate-shaped, are slidably disposed between two side plates 110, and spaced apart along a second direction Y. Each drainage board 200 has a first elastic block 210 on both sides along the second direction Y, with the first elastic block 210 located near a first end of the drainage board 200 along a third direction Z. Exemplarily, the drainage board 200 may be made of a metal material, thereby giving it high rigidity. The first elastic block 210 may be either a polyurethane block or a rubber block, and its rigidity can be adjusted as needed. The connection method between the first elastic block 210 and the drainage board 200 can be determined as needed.

[0067] A filter bag 300 is disposed between two adjacent drainage plates 200 and connected to the drainage plates 200. Exemplarily, the filter bag 300 can be made of high-strength filter cloth, enabling it to withstand strong pressure without rupture. The specific material of the filter bag 300 can be determined based on needs. A cavity (i.e., a filter chamber) is formed inside the filter bag 300, facilitating the injection of the material to be filtered into the filter bag 300. In other words, in this embodiment, the filter chamber is entirely surrounded by the filter bag 300, and the drainage plates 200 only serve the function of pressure filtration and drainage. There is no need for the drainage plates 200 to abut against and form the filter chamber, thus simplifying the structure of the drainage plates 200. The filter bag 300 has a discharge port (not shown in the figure) at its first end (i.e., the bottom surface of the filter bag) along the third direction Z. Two adjacent first elastic blocks 210 can abut against the two sides of the filter bag 300 along the second direction Y to seal the discharge port. The filter bag 300 is also provided with a feed inlet 310. For example, it can be connected to the cavity inside the filter bag 300 through a feed pipe. The feed inlet is formed at the end of the feed pipe away from the filter bag 300.

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

[0069] In this embodiment of the bag filter press, "bag stacking" means that the filter chambers on the filter press are entirely formed by the filter bags 300 themselves, and the drainage plates 200 only serve the function of filtration and drainage, without forming filter chambers. One or more filter bags 300 can be placed between two adjacent drainage plates 200 to form one or more filter chambers.

[0070] A feeding device 400 is provided on at least one side of the frame 100 along a first direction X. The feeding device 400 includes a main feeding pipe 410 and multiple feeding branch pipes 420 connected to the main feeding pipe 410. The multiple feeding branch pipes 420 are respectively connected to multiple feeding ports 310, that is, each branch feeding pipe is connected to a filter bag 300. During feeding, the main feeding pipe 410 is used to simultaneously add the filter material to be filtered into multiple filter bags 300 through the multiple feeding branch pipes 420, thereby ensuring that the feeding time of multiple filter bags 300 is approximately the same. For example, the main feed pipe 410 in this embodiment can be a rigid pipe, and the feed branch pipe 420 can be a flexible pipe. The main feed pipe 410 can be connected to multiple feed branch pipes 420 through a feed controller 430 or other equipment, thereby controlling the amount of filter material entering each feed branch pipe 420. A control valve 440 can be provided between the feed branch pipe 420 and the feed controller 430, and the opening or closing of the feed branch pipe 420 can be controlled by the control valve 440.

[0071] A drive unit 500 is located on one side of the frame 100 along the second direction Y. The drive unit 500 is used to drive the drain plate 200 to move along the second direction Y to press and filter the filter bags 300. For example, the drive unit 500 may include a hydraulic cylinder or a pneumatic cylinder, which pushes the pressure plate to move along the second direction Y, thereby achieving the pressing and filtration of multiple filter bags 300.

[0072] In this embodiment, the filter bag 300 is placed between two adjacent drainage plates 200, forming a filter chamber by the filter bag 300 itself. The first elastic block 210 on the two adjacent drainage plates 200 abuts against the filter bag 300 to seal the discharge port of the filter bag 300, thereby ensuring the sealing of the discharge port. During feeding, the main feed pipe 410 can simultaneously add the material to be filtered into multiple filter bags 300 through multiple feed branch pipes 420, so that the feeding time of each filter bag 300 is roughly the same, which helps to ensure the consistency of the moisture content, thickness, etc. of the subsequent filter cake.

[0073] In this embodiment, the feed inlet 310 can be located on at least one side of the filter bag 300 along the first direction X. Alternatively, the feed inlet 310 can be located 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 location of the feed inlet 310 can be determined as needed.

[0074] Preferably, such as Figure 2 As shown, in this embodiment, the filter bag 300 has inlets 310 on both sides along the first direction X. Therefore, the material to be filtered can be simultaneously injected into the filter bag 300 through the feeding devices 400 on both sides, which helps to ensure the uniformity of material feeding into the filter bag 300.

[0075] In this embodiment, the drainage plate 200 is provided with water distributors 250 on both sides along the first direction X. The lower end of the water distributor 250 can be connected to the feed pipe 420, and the upper end of the water distributor 250 is connected to the feed inlet 310 through a pagoda connector or the like.

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

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

[0078] For example, in this embodiment, the filter bag hanger 230 is provided with two suspension rods 231 on both sides along the second direction Y, and the filter bag 300 is provided with two corresponding hanging ears 320. The filter bag 300 is suspended on the two suspension rods 231 on the same side through the two hanging ears 320. The drainage plate 200 can be connected to the filter bags 300 on both sides along the second direction Y through the suspension rods 231 on both sides. It can be understood that multiple filter bags 300 can be connected to the suspension rods 231 on the same side at the same time.

[0079] Please continue to refer to Figure 3 In this embodiment, the drainage plate 200 has first mounting grooves on both sides along the second direction Y. The first mounting grooves are close to the first end of the drainage plate 200 along the third direction Z. The first elastic block 210 is interference-fitted with the first mounting groove. Specifically, the first mounting groove can be, for example, a dovetail groove. The first elastic block 210 is partially pressed into the dovetail groove, thereby achieving an interference fit with the drainage plate 200.

[0080] like Figure 3As shown, in this embodiment, the drainage plate 200 is further provided with second elastic blocks 240 on both sides along the second direction Y. 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 either a polyurethane block or a rubber block, and the hardness of the second elastic block 240 can be adjusted as needed.

[0081] In this embodiment, during the filter press process, 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 blocks 240 can be made of a material with an elastic modulus lower than that of the filter bag 300. During filter press, the second elastic blocks 240 can absorb part of the deformation of the filter cake, reducing the pressure of the filter cake on the filter bag 300. After the filter bag 300 is compressed by the second elastic blocks 240 on both sides, the filter cake inside deforms accordingly, forming a locally thinner area. It can be understood that this area is located between two adjacent sub-cavities. Because this area is thinner, it is easier to break during subsequent vibration, thereby reducing the probability of the filter cake sticking to the filter bag 300 and improving the safety of using the stacked bag filter press.

[0082] Furthermore, in this embodiment, at least one groove 241 is formed at the end of the second elastic block 240 opposite to the drainage plate 200. The groove 241 allows the filtrate to flow between the sub-cavities on both sides of the second elastic block 240, making the pressure in adjacent sub-cavities the same. In addition, the second elastic block 240 functions to divide the filter cake. When used in conjunction with the rapping device 600, the filter cake is easily broken at this point during unloading, thereby reducing the difficulty of unloading the filter bag 300.

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

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

[0085] Please continue to refer to Figure 1 and Figure 6 The stacked bag filter press of this embodiment also includes a vibrating device 600. A second track 130 is provided on the side plate 110. The vibrating device 600 can slide along the second track 130. The vibrating device 600 is used to separate the filter bag 300 from the filter cake inside after the filter press is completed.

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

[0087] Furthermore, the rapping device 600 includes rapping grippers 640 for gripping or releasing the filter bag 300, and a power mechanism 630 for raising the gripped filter bag 300 to a preset height. During rapping, the rapping grippers 640 can pick up the filter bag 300 from the drainage plate 200, and after being raised to a preset height by the power mechanism 630, the rapping grippers 640 release the filter bag 300, causing the filter bag 300 to fall onto the frame 100. The impact force during the fall causes friction between the filter cake inside the filter bag 300 and the filter bag 300, thus completing the unloading.

[0088] In this embodiment, the rapping device 600 also includes a gantry frame 620, with two track trolley mechanisms 610 connected to both ends of the gantry frame 620. The power mechanism 630 and the rapping gripper 640 are both mounted on the gantry frame 620. The power mechanism 630 is used to drive the rapping gripper 640 to move along the third direction Z, so that the rapping gripper 640 can grip or release the filter bag 300.

[0089] Specifically, the gantry 620 is connected to two track trolley mechanisms 610 at its two ends along the first direction X. When the track trolley mechanisms 610 slide along the second track 130, they can drive the gantry 620 to move synchronously. The gantry 620 provides a mounting base for the power mechanism 630 and the vibrating gripper 640; for example, the power mechanism 630 may include a hydraulic cylinder or a pneumatic cylinder. When the power mechanism 630 drives the vibrating gripper 640 to move along the third direction Z, the vibrating gripper 640 can open or close, thereby gripping or releasing the filter bag 300.

[0090] The vibrating device 600 in this embodiment also includes a gripper link 650, and a vibrating gripper 640 is disposed on the side of the gripper link 650 facing the filter bag 300. The gantry frame 620 is provided with power mechanisms 630 on both sides along the first direction X. The output ends of the two power mechanisms 630 are respectively connected to the two ends of the gripper link 650. The power mechanisms 630 are used to drive the gripper link 650 to move along the third direction Z. That is, in this embodiment, the gripper link 650 can be moved along the third direction Z by the extension and retraction of the power mechanisms 630 on both sides. When the gripper link 650 moves along the third direction Z, it can simultaneously drive the vibrating gripper 640 on it to move along the third direction Z, so that the vibrating gripper 640 can grip or release the filter bag 300.

[0091] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8 Furthermore, in this embodiment, a filter bag holder 230 is provided at the second end of the drainage plate 200 along the third direction Z. The filter bag holder 230 is detachably mounted on the drainage plate 200, and the filter bag 300 is located on at least one side of the filter bag holder 230 along the second direction Y. Exemplarily, the filter bag holder 230 can be inserted into the drainage plate 200. When the power mechanism 630 drives the gripper connecting rod 650 to move toward the filter bag holder 230, the vibrating gripper 640 can abut against the filter bag holder 230, so that the vibrating gripper 640 opens and grips the filter bag holder 230, thereby gripping the filter bag holder 230 together with the filter bags 300 on both sides and driving it to rise along the third direction Z.

[0092] In this embodiment, the filter bag holder 230 is equipped with a gripping trigger, and the gantry frame is equipped with a release trigger. When the vibrating gripper 640 moves along the third direction Z and contacts the gripping trigger, the vibrating gripper 640 opens and grips the filter bag holder 230. When the vibrating gripper 640 moves along the third direction Z and contacts the release trigger, the vibrating gripper 640 releases the filter bag holder 230.

[0093] Specifically, such as Figure 7 As shown, the vibratory gripper 640 includes two claw blocks 641 arranged opposite each other along the second direction Y, two baffle plates 642 arranged opposite each other along the first direction X, and a connecting plate 643. The two baffle plates 642 are located on both sides of the claw blocks 641, and the claw blocks 641 and the baffle plates 642 are rotatably connected. The two claw blocks 641 can open or close when rotating relative to the baffle plates 642. The connecting plate 643 connects the two baffle plates 642 and the gripper connecting rod 650. The connecting plate 643 can be connected to the baffle plates 642 and the gripper connecting rod 650, for example, by fasteners such as bolts, thereby fixing the vibratory gripper 640 and the gripper connecting rod 650.

[0094] The vibrating gripper 640 moves along the third direction Z to contact the gripping trigger, and the gripper block 641 can rotate relative to the baffle plate 642 to open the vibrating gripper 640 and grip the filter bag holder 230. The vibrating gripper 640 moves along the third direction Z to contact the release trigger, and the gripper block 641 can rotate relative to the baffle plate 642 to release the filter bag holder 230.

[0095] like Figure 8 As shown, the claw block 641 includes a hinge portion 6411 and a first claw bar 6412, a second claw bar 6413, and a third claw bar 6414 connected to the hinge portion 6411. The hinge portion 6411 is hinged to the baffle plate 642; for example, the hinge can be achieved through a component such as a pin.

[0096] The first claw 6412 is connected to the first end of the hinge portion 6411 along the third direction Z. A first abutment portion 64121 is formed at the end of the first claw 6412 away from the hinge portion 6411. The first abutment portion 64121 is disposed toward the other claw block 641, and the size of the first abutment portion 64121 gradually decreases along the second direction Y in the direction away from the hinge portion 6411. That is, the first abutment portion 64121 has an inclined surface disposed toward the other claw block 641.

[0097] The second claw bar 6413 is connected to the second end of the hinge portion 6411 along the third direction Z. The second claw bar 6413 includes a first segment 64131 and a second segment 64132 connected to each other. The first segment 64131 is connected to the hinge portion 6411 and extends in the second direction Y toward a side opposite to the other claw block 641. The second segment 64132 is connected to the first segment 64131 and extends in the second direction Y toward a side opposite to the other claw block 641. That is, the second segment 64132 has an inclined surface that is opposite to the other claw block 641.

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

[0099] When the vibrating gripper 640 moves along the third direction Z, the first gripper bar 6412 abuts against the gripping trigger, thereby causing the vibrating gripper 640 to open and grip the filter bag holder 230. The second gripper bar 6413 abuts against the release trigger, thereby causing the vibrating gripper 640 to release the filter bag holder 230.

[0100] like Figure 4As shown, the filter bag holder 230 includes a holder body 232, an adapter plate 233, and a suspension rod 231. The projection of the holder body 232 in a plane perpendicular to the first direction X is approximately "I"-shaped. Adapter plates 233 are connected to both sides of the holder body 232 along the second direction Y, and the suspension rod 231 is connected to the adapter plates 233. The gripping trigger includes an opening trigger block 2321 disposed at the second end of the holder body 232 along the third direction Z, extending along the second direction Y. When the vibrating gripper 640 moves towards the opening trigger block 2321 along the third direction Z, the first claw bars 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 bars 6412 move away from each other, thereby causing the vibrating gripper 640 to open. 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 includes two vibrating trigger blocks 621 arranged opposite each other along the second direction Y. Each vibrating trigger block 621 includes a connecting section 6211 and a trigger section 6212, which 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 the end of the connecting section 6211 facing away from the gantry 620, extending towards the other vibrating trigger block 621.

[0102] When the vibrating gripper 640 moves along the third direction Z toward the vibrating trigger block 621, the second claw bars 6413 of the two claw blocks 641 can respectively abut against the two vibrating trigger blocks 621, so that the two first claw bars 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 inside.

[0103] Please continue to refer to Figure 8 In this embodiment, the vibrating gripper 640 also includes an elastic element. An elastic element mounting seat 644 is provided on the side of the second claw bar 6413 facing the other claw block 641, and the two ends of the elastic element are respectively sleeved on the two elastic element mounting seats 644. In the free state, the two ends of the elastic element apply elastic force to the two second claw bars 6413, and the third claw bars 6414 of the two claw blocks 641 abut against each other, thereby keeping the vibrating gripper 640 in a closed state. When the vibrating gripper 640 opens, it can compress the elastic element. Furthermore, when the power mechanism 630 drives the gripper connecting rod 650 through the opening trigger block 2321, the elastic restoring force of the elastic element can close the vibrating gripper 640 and clamp the filter bag hanger 230.

[0104] It is understandable that the rapping device 600 can move along the second direction Y to either side of any drainage plate 200, and through the above process, realize the process of clamping, lifting and releasing the filter bag hanger 230, thereby completing the rapping unloading.

[0105] During installation of the stacked bag filter press in this embodiment, the filter bags 300 are first suspended on both sides of the drainage plate 200. It can be understood that one or more filter bags 300 can be placed between two adjacent drainage plates 200, and the specific number of suspended filter bags 300 can be set as needed. Then, the drainage plates 200 with the suspended filter bags 300 can be placed sequentially 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 rails 120 on the side plate 110. In use, the drive device 500 is activated to initially compress the drainage plates 200, and the two first elastic blocks 210 on adjacent drainage plates 200 seal the discharge port. The feeding device 400 is activated, and multiple feeding branches 420 connected to the main feeding pipe 410 simultaneously inject the material to be filtered into multiple filter bags 300, ensuring that the feeding time of each filter bag 300 is approximately the same, which helps to ensure the consistency of the moisture content, thickness, etc., of the subsequent filter cake. After the material is fed in, the pressure of the drive device 500 is increased, and the drive device 500 is used to press the filter bags 300 between the drainage plates 200 to remove excess water from the material to be filtered inside the filter bags 300. After the pressing is completed, the drive device 500 is released, the discharge port of the filter bags 300 is opened, and the vibrating device 600 is started, so that the vibrating device 600 moves along the second track 130 to above the filter bags 300 to be discharged; first, the drainage plates 200 are opened a certain distance, and the power mechanism 630 drives the vibrating claws 640 to move towards the drainage plates 200. After the vibrating claws 640 contact the opening trigger block 2321, they open and then clamp the filter bag hangers 230 on the drainage plates 200, holding the filter bag hangers 230 together with the filter bags 300 on both sides. Subsequently, the power mechanism 630 drives the vibrating gripper 640 to move away from the drainage plate 200. After the vibrating gripper 640 contacts the vibrating trigger block 621 on the gantry 620, it opens and releases 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 inside. The vibrating device 600 moves along the second track 130 to the next filter bag 300 to be unloaded, and repeats the above process until all filter bags 300 are unloaded.
