Abstract

This invention discloses a filter plate for a filter press that facilitates the replacement of the diaphragm and filter cloth, relating to the field of diaphragm filter press technology. It includes an outer frame assembled from a filter plate and a second mounting plate. The outer frame contains a fixed plate, side plates on both sides of the fixed plate, and a filter cloth fixed to the side of the side plates away from the fixed plate. A diaphragm is disposed in the side plates between the fixed plate and the filter cloth. A pusher mechanism is symmetrically slidably disposed in the fixed plate. By incorporating the pusher mechanism, the distance between the pusher mechanism and the filter cloth can be adjusted before filtration in the filter press. When the distance decreases, the air-filling space in the diaphragm decreases, allowing the diaphragm to quickly fill with gas, thereby achieving rapid compression of the filter cake and improving the working efficiency of the filter press.

Description

Technical Field

[0001] This invention relates to the field of diaphragm filter press technology, and more specifically to a filter press filter plate that facilitates the replacement of diaphragms and filter cloths. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to the substance to be filtered, causing the liquid to seep out. It is a commonly used solid-liquid separation device. The diaphragm plate and frame filter press is a well-known variable-volume plate and frame filter press, an intermittent solid-liquid separation device. Under the pressure of the feed pump, the slurry is sent into the filter chamber. Through the filter medium, the solid and liquid are separated, forming a primary filter cake. Then, a high-pressure fluid or gas is injected into the diaphragm cavity, causing the diaphragm to bulge and apply pressure to the filter cake in the opposite direction, thereby reducing the moisture content of the filter cake. After the filtration process is completed, the primary filter cake is subjected to high-pressure compression again. The resulting secondary filter cake has a moisture content 10%-40% lower than the primary filter cake.

[0003] Chinese invention patent application CN202111467377.4 discloses a filter plate and a diaphragm filter press that facilitates the replacement of diaphragms and filter cloths. The filter plate has an installation groove in which a filter assembly is installed. A through groove is also provided on the filter plate, communicating with the filter assembly. The filter assembly includes an installation plate, a fixing plate, a first filter element, a second filter element, and clamping components. The fixing plate is fixedly mounted on the installation plate, and the first and second filter elements are respectively mounted on both sides of the fixing plate. The clamping components are symmetrically arranged on both sides of the installation plate. Although the diaphragm and filter cloth can be removed from the filter plate sequentially, the filter cloths must be connected one by one via connecting shafts when disassembling them. This is not only complex to operate, but the first spring also makes it difficult to disassemble the connecting shafts. Furthermore, given the large and fixed space within the diaphragm, the inflation time is long, ultimately resulting in low filter press efficiency.

[0004] Therefore, it is necessary to propose a filter plate for a filter press that facilitates the replacement of the diaphragm and filter cloth to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of cumbersome filter cloth installation, inconvenient disassembly, and low working efficiency of existing filter presses.

[0006] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0007] A filter press plate for easy replacement of diaphragm and filter cloth includes an outer frame assembled from the filter plate and a second mounting plate. The outer frame contains a fixed plate, side plates on both sides of the fixed plate, and a filter cloth fixed to the side of the side plates away from the fixed plate. A diaphragm is disposed in the side plates between the fixed plate and the filter cloth. A pusher mechanism is symmetrically slidably disposed in the fixed plate. The pusher mechanism is used to adjust the air space between the side of the pusher mechanism away from the fixed plate and the filter cloth, and a transmission pipe is connected to this air space. The filter cloth is fixed to the side plates by the mounting mechanism, which fixes the fixed plate and the side plates relatively.

[0008] Furthermore, the fixed plate has a through-type first sliding groove in the middle, and the push plate mechanism includes a push plate assembly symmetrically slidably disposed in the first sliding groove, a power assembly for driving the push plate assembly to slide symmetrically, and an auxiliary assembly for assisting the push plate assembly to slide smoothly.

[0009] Furthermore, the upper and lower ends of the first sliding groove are connected to guide grooves, and the auxiliary component includes an intermediate plate fixedly connected to the middle of the guide groove. The two ends of the intermediate plate are symmetrically fixedly connected to first springs, and the end of the first spring away from the intermediate plate is fixedly connected to the push plate assembly.

[0010] Furthermore, the size of the first sliding groove is larger than the space in the middle of the frame plate. The push plate assembly includes a sliding plate and an extrusion plate. The extrusion plate is slidably connected in the first sliding groove. Guide plates are symmetrically fixedly connected to the upper and lower ends of the extrusion plate. The guide plates are slidably connected in the guide groove. The sliding plate is fixed on the side of the extrusion plate facing the frame plate, and the outer side of the sliding plate is closely fitted to the space in the middle of the frame plate.

[0011] Furthermore, the power assembly includes a transmission rod rotatably connected to the side of the sliding plate away from the sliding plate, a transmission plate rotatably connected to the end of the transmission rod away from the sliding plate, and an electric push rod fixedly connected in the first sliding groove. The output end of the electric push rod is fixedly connected to the transmission plate. Mounting strips are fixedly connected to both sides of the first sliding groove, and a feeding pipe is fixedly connected to the end of the mounting strip away from the first sliding groove.

[0012] Furthermore, the fixed plate has symmetrically provided connecting through holes on its four sides. The mounting mechanism includes a connecting mechanism provided on one side of the pressure ring, a locking mechanism provided in the connecting through hole for locking the connecting mechanism, and a synchronizing mechanism for driving the locking mechanism to open and close synchronously. The side of the frame plate facing the fixed plate is fixedly connected with a positioning ring with the same diameter as the connecting through hole.

[0013] Furthermore, the locking mechanism includes a first mounting plate fixedly connected to the middle of the connecting through hole, a connecting shaft rotatably connected to the upper end of the first mounting plate and coaxial with the connecting through hole, strip plates fixedly connected to both ends of the connecting shaft, a circular plate fixedly connected to the outer circumferential surface of the connecting shaft, a partition plate disposed on the circumferential edge of the circular plate, a transmission belt and a torsion spring fixedly connected to the outer surface of the partition plate, a transmission space being provided between the outer side of the partition plate and the connecting through hole, the transmission belt being disposed in the transmission space, and one end of the transmission belt away from the partition plate passing through the fixed plate, one end of the torsion spring being fixedly connected to the outer side of the circular plate, and the other end of the torsion spring being fixed in the connecting through hole.

[0014] Furthermore, the connecting mechanism includes a connecting cylinder symmetrically fixedly connected to one side of the pressure ring, an insertion groove opened at the end of the connecting cylinder away from the pressure ring for inserting the connecting shaft and the strip plate, and a strip groove communicating with the insertion groove for inserting the strip plate, the strip groove extending through the end of the connecting cylinder.

[0015] Furthermore, a second sliding groove is provided on the circular plate, and a limiting rod is fixedly connected to the first mounting plate. The limiting rod is slidably disposed in the second sliding groove. Under the action of external force, the torsion spring is parallel to the strip groove and the strip plate, and the limiting rod is attached to one end of the second sliding groove.

[0016] Furthermore, the synchronization mechanism includes a side groove formed on the outer side of the fixed plate, a synchronization rod slidably connected in the side groove on each side of the fixed plate, and a connecting belt that connects multiple synchronization rods in series. One end of the transmission belt that extends out of the fixed plate is fixed to the synchronization rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention, by setting a pusher plate mechanism, can adjust the distance between the pusher plate mechanism and the filter cloth before the filter press performs filtration. When the distance is reduced, the air space in the diaphragm is reduced, so that the diaphragm can be quickly filled with gas, thereby achieving rapid compression of the filter cake and improving the working efficiency of the filter press.

[0019] 2. The present invention, through the setting of the installation mechanism, can realize the synchronous disassembly of the filter cloth on both sides of the fixed plate, thereby disassembling the diaphragm. At the same time, through the cooperation of the locking mechanism and the synchronization mechanism, the filter cloth can also be quickly disassembled.

[0020] 3. The present invention, through the arrangement of the circular plate and the partition, can achieve stable driving of the circular plate, thereby achieving precise matching between the connecting shaft and the connecting cylinder.

[0021] 4. In this invention, through the coordinated arrangement between the torsion spring and the synchronization mechanism, the strip plate and the strip groove can be misaligned after the torsion spring recovers its deformation, thereby achieving rapid locking of the connecting cylinder.

[0022] 5. The present invention, through the cooperative arrangement between the electric push rod and the first spring, can achieve stable driving of the extrusion plate, thereby preventing the extrusion plate from getting stuck in the first sliding groove. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figure 1-8 A filter press plate for easy replacement of diaphragm and filter cloth includes an outer frame assembled from a filter plate 3 and a second mounting plate 32. The second mounting plate 32 is fixed to the filter plate 3 by bolts. Ear plates 33 are provided on the outer sides of both the second mounting plate 32 and the filter plate 3. A fixing plate 1, side frame plates 2 on both sides of the fixing plate 1, and a filter cloth 31 fixed to the side of the side frame plate 2 away from the fixing plate 1 are provided in the outer frame. A diaphragm (the diaphragm structure is not shown in the figure) is provided in the side frame plate 2 between the fixing plate 1 and the filter cloth 31. The fixing plate 1 has symmetrical sliding... A push plate mechanism is provided to adjust the air space between the side of the push plate mechanism away from the fixed plate 1 and the filter cloth 31. The air space is connected to the transmission pipe 35. The air space can be filled with both gas and liquid. In order to ensure the service life of the diaphragm and prevent the push plate mechanism from squeezing the diaphragm, the side of the diaphragm facing the filter cloth 31 is fixed to the inner side of the frame plate 2. The filter cloth 31 is fixed to the frame plate 2 by the mounting mechanism, and the mounting mechanism makes the fixed plate 1 and the frame plate 2 relatively fixed.

[0034] Specifically, in combination Figure 3 and Figure 4 As shown, a through-type first sliding groove 4 is provided in the middle of the fixed plate 1. The shape of the first sliding groove 4 is consistent with the shape of the middle part of the fixed plate 1 and the frame plate 2, but the size of the first sliding groove 4 is larger than that of the middle part of the fixed plate 1 and the frame plate 2. The push plate mechanism includes a push plate assembly symmetrically slidably arranged in the first sliding groove 4, a power assembly for driving the push plate assembly to slide symmetrically, and an auxiliary assembly for assisting the push plate assembly to slide smoothly, so as to achieve smoothness when pushing the push plate assembly and prevent jamming.

[0035] Specifically, in combination Figure 3 and Figure 4 As shown, the upper and lower ends of the first sliding groove 4 are connected to guide grooves. The auxiliary component includes an intermediate plate 7 fixedly connected to the middle of the guide groove. The two ends of the intermediate plate 7 are symmetrically fixedly connected to a first spring 8. The end of the first spring 8 away from the intermediate plate 7 is fixedly connected to the push plate assembly.

[0036] Specifically, in combination Figure 2As shown, the size of the first sliding groove 4 is larger than the space in the middle of the frame plate 2. The push plate assembly includes a sliding plate 5 and an extrusion plate 6. The extrusion plate 6 is slidably connected in the first sliding groove 4. Guide plates are symmetrically fixedly connected to the upper and lower ends of the extrusion plate 6. The guide plates are slidably connected in the guide groove. The sliding plate 5 is fixed on the side of the extrusion plate 6 facing the frame plate 2, and the outer side of the sliding plate 5 is tightly fitted to the space in the middle of the frame plate 2. To further ensure the smooth sliding of the push plate assembly, a guide rod can also be set in the guide groove. The guide plate is slidably connected to the outside of the guide rod, and the first spring 8 is sleeved on the outside of the guide rod.

[0037] Specifically, in combination Figure 3 and Figure 4 As shown, the power assembly includes a transmission rod 13 rotatably connected to the side of the sliding plate 5 away from the sliding plate 5, a transmission plate 12 rotatably connected to the end of the transmission rod 13 away from the sliding plate 5, and an electric push rod 11 fixedly connected in the first sliding groove 4. The output end of the electric push rod 11 is fixedly connected to the transmission plate 12. The stroke of the electric push rod 11 is constant. When the electric push rod 11 is extended to its longest state, the space between the extrusion plate 6 and the filter cloth 31 is minimized, and the speed of filling with gas or liquid is the fastest. At the same time, in order to ensure sealing, a sealing layer can be provided on the outer edge of the sliding plate 5 to prevent gas or liquid from flowing out. In addition, in order not to affect the material conveying, mounting strips 10 are fixedly connected to both sides of the first sliding groove 4. A feeding pipe 9 is fixedly connected to the end of the mounting strip 10 away from the first sliding groove 4, so that the position of the feeding pipe 9 is fixed and does not change, and does not affect the drive of the power assembly.

[0038] Specifically, in combination Figure 2-7 As shown, the four sides of the fixing plate 1 are symmetrically provided with connecting through holes 14. The installation mechanism includes a connecting mechanism provided on one side of the pressure ring 34, a locking mechanism provided in the connecting through hole 14 for locking the connecting mechanism, and a synchronizing mechanism for driving the locking mechanism to open and close synchronously. The side of the frame plate 2 facing the fixing plate 1 is fixedly connected with a positioning ring 23 with the same diameter as the connecting through hole 14, thereby realizing the synchronous installation and disassembly of the filter cloth 31 and improving work efficiency.

[0039] Specifically, in combination Figure 2-7As shown, the locking mechanism includes a first mounting plate 15 fixedly connected to the middle of the connecting through hole 14, a connecting shaft 16 rotatably connected to the upper end of the first mounting plate 15 and coaxial with the connecting through hole 14, strip plates 26 fixedly connected to both ends of the connecting shaft 16, a circular plate 17 fixedly connected to the outer circumferential surface of the connecting shaft 16, a partition plate 18 disposed on the circumferential edge of the circular plate 17, a transmission belt 30 and a torsion spring 19 fixedly connected to the outer surface of the partition plate 18. To ensure the stability of the transmission belt 30, the outer edge of the circular plate 17 is pressed against the ground. The connecting through hole 14 is connected, and a transmission space is provided between the outer side of the partition plate 18 and the connecting through hole 14. The transmission belt 30 is set in the transmission space, and the end of the transmission belt 30 away from the partition plate 18 passes through the fixing plate 1, so as to prevent the transmission belt 30 from detaching from the circular plate 17 when the transmission belt 30 is pulled. One end of the torsion spring 19 is fixedly connected to the outer side of the circular plate 17, and the other end of the torsion spring 19 is fixed in the connecting through hole 14. The setting of the torsion spring 19 can facilitate the locking and opening of the connecting cylinder 22, so that the positioning of the strip plate 26 is more accurate.

[0040] Specifically, in combination Figure 2-8 As shown, the connecting mechanism includes a connecting cylinder 22 symmetrically fixedly connected to one side of the pressure ring 34, an insertion groove 24 opened at the end of the connecting cylinder 22 away from the pressure ring 34 for the insertion of the connecting shaft 16 and the strip plate 26, and a strip groove 25 communicating with the insertion groove 24 for the insertion of the strip plate 26. The strip groove 25 passes through the end of the connecting cylinder 22. When the strip plate 26 is inserted into the insertion groove 24, the timing rod 28 is released and the strip plate 26 is driven to rotate in the insertion groove 24 under the action of the torsion spring 19, thereby locking the connecting cylinder 22.

[0041] Specifically, a second sliding groove 20 is provided on the circular plate 17, and a limiting rod 21 is fixedly connected to the first mounting plate 15. The limiting rod 21 is slidably disposed in the second sliding groove 20. The longitudinal sections of the second sliding groove 20 and the limiting rod 21 are both arc-shaped. As the circular plate 17 rotates, the second sliding groove 20 will slide along the outer side of the limiting rod 21. When the connecting cylinder 22 is installed, the torsion spring 19 is subjected to external force, and the strip groove 25 and the strip plate 26 are parallel, and the limiting rod 21 is attached to one end of the second sliding groove 20, so that...

[0042] Specifically, in combination Figure 3 As shown, the synchronization mechanism includes a side groove 27 formed on the outer side of the fixed plate 1, a synchronization rod 28 slidably connected in the side groove 27 on each side of the fixed plate 1, and a connecting belt 29 that connects multiple synchronization rods 28 in series. One end of the transmission belt 30 that passes through the fixed plate 1 is fixed to the synchronization rod 28. In order not to affect the installation of the fixed plate 1, the height of the synchronization rod 28 should be lower than the depth of the side groove 27. The connecting belt 29 fits tightly against the side groove 27, thereby realizing the synchronous movement between multiple synchronization rods 28.

[0043] Working principle: First, during installation, align the positioning ring 23 with the corresponding connecting through hole 14, then push the frame plate 2 to fit with the fixing plate 1. After fitting, place the filter cloth 31 on the frame plate 2, insert the connecting cylinder 22 through the filter cloth 31 into the connecting through hole 14, and simultaneously push the synchronizing rod 28 to slide along the side groove 27, so that the synchronizing rod 28 drives the transmission belt 30 to move, the transmission belt 30 in turn drives the partition plate 18 to move, and then drives the circular plate 17 to rotate. When the other end of the second sliding groove 20 fits with the limiting rod 21, the strip plate 26 and the strip... When the groove 25 is flush, press the pressure ring 34 to insert the strip groove 25 into the outside of the strip plate 26. When the pressure ring 34 is pressed on the side plate 2, the strip plate 26 moves into the strip groove 25. Then release the synchronizing rod 28. Under the action of the torsion spring 19, the circular plate 17 is reset, so that the strip groove 25 and the strip plate 26 are misaligned, thereby locking the connecting cylinder 22. Then the fixing plate 1 and the side plate 2 are installed in the filter plate 3 as a whole. Then the second mounting plate 32 is installed on the filter plate 3 to complete the overall installation of the filter plate 3.

[0044] When the filter press is working, by controlling the extension of the electric push rod 11, the thrust of the electric push rod 11 is transmitted to the sliding plate 5 through the transmission plate 12 and the transmission rod 13, which in turn pushes the sliding plate 5 to slide along the first sliding groove 4 toward the filter cloth 31, thereby squeezing the diaphragm to reduce the space in the diaphragm, thereby reducing the rate at which the gas fills the diaphragm and facilitating the gas to quickly squeeze the filter cake.

[0045] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
