A mounting plate 19 is installed on one side of the mounting bracket 15 via a first moving mechanism. The first moving mechanism includes a first motor 16 fixedly installed on one side of the mounting bracket 15. A lead screw 17 is fixedly installed at the output end of the first motor 16. A first moving block 18 is threaded onto the surface of the lead screw 17. The bottom of the first moving block 18 and the top of the mounting plate 19 are fixedly installed to facilitate the movement of the mounting plate 19. A lifting plate 28 is fixedly installed at one end of the sliding column 11. A fixing plate 29 is fixedly installed on the inner wall of the mounting bracket 15. The bottom of the lifting plate 28 and the top of the fixing plate 29 are in conjunction. A slide rail 22 is installed on the bottom of the mounting plate 19 via a lifting mechanism. The lifting mechanism includes an electric push rod 20 fixedly installed on the bottom of the mounting plate 19. A push plate 21 is fixedly installed at the output end of the electric push rod 20. The bottom of the push plate 21 and the top of the slide rail 22 are fixedly installed to facilitate the lifting and lowering of the slide rail 22.

[0022] Specifically, the inner wall of the slide rail 22 is fitted with a pin 27 via a second moving mechanism. The second moving mechanism includes a second motor 23 fixedly installed on the inner wall of the slide rail 22. A bidirectional threaded rod 24 is fixedly installed at the output end of the second motor 23. A second moving block 25 is threaded onto the surface of the bidirectional threaded rod 24. A connecting plate 26 is fixedly installed at the bottom of the second moving block 25. One side of the connecting plate 26 and one end of the pin 27 are fixedly installed to facilitate the movement of the pin 27. The surface of the pin 27 mates with the inner wall of the slot 3. There are two sets of the second moving block 25, the connecting plate 26, and the pin 27, arranged symmetrically. The pin 27 is lowered by a lifting mechanism and moved by a first moving mechanism, so that the pin 27 is located on one side of the slot 3. The two sets of pins 27 are moved towards each other by the second moving mechanism, so that the pin 27 is inserted into the slot. The filter plate 2 can be clamped by the inner wall of the mounting groove 3. The filter plate 2 is lifted by the lifting mechanism and moved by the first moving mechanism, so that the lifting plate 28 moves above the fixed plate 29. The filter plate 2 is lowered by the lifting mechanism, and the lifting plate 28 contacts the fixed plate 29. The lifting plate 28 drives the mounting column 14 away from the inner wall of the mounting groove 7, so that the filter cloth body 9 can be removed. The new filter cloth body 9 is placed on the surface of the diaphragm plate 8, and the positioning block 5 is inserted into the inner wall of the positioning groove 4. The filter cloth body 9 can be pressed by the pressure frame 6. The lifting mechanism drives the lifting plate 28 away from the top of the fixed plate 29. The reset mechanism drives the mounting column 14 to insert into the inner wall of the mounting groove 7, so that the pressure frame 6 is limited and installed, thereby allowing the filter cloth body 9 to be installed. This achieves the purpose of quick and easy replacement of the filter cloth body 9. The structure is simple and easy to use.

[0023] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0024] In use: When using this filter press that facilitates filter cloth replacement, when the filter cloth body 9 needs to be replaced, the electric push rod 20 drives the push plate 21 to descend, the push plate 21 drives the slide rail 22 to descend, the slide rail 22 drives the insertion post 27 to descend, the first motor 16 drives the lead screw 17 to move, the lead screw 17 drives the first moving block 18 to move, the first moving block 18 drives the mounting plate 19 to move, and the mounting plate 19 drives the insertion post 27 to move, so that the insertion post 27 is located on one side of the slot 3. The second motor 23 drives the bidirectional threaded rod 24 to rotate, which in turn drives two sets of second moving blocks 25 to move in opposite directions. The second moving blocks 25 then drive the connecting plate 26 to move in opposite directions, which in turn drives two sets of insert pins 27 to move in opposite directions. This causes the insert pins 27 to insert into the inner wall of the slot 3, clamping the filter plate 2. The electric push rod 20 then drives the insert pins 27 to rise, which in turn causes the filter plate 2 to rise. Finally, the first motor 16 drives the insert pins 27 to move, causing the insert pins 27 to... The filter plate 2 is moved, causing the lifting plate 28 to move above the fixed plate 29. The filter plate 2 is then lowered via the electric push rod 20. During this process, the lifting plate 28 contacts the fixed plate 29, causing the fixed plate 29 to lift the lifting plate 28. The lifting plate 28 then moves the sliding column 11, which in turn moves the moving plate 13. The moving plate 13 then moves the mounting column 14, causing it to leave the inner wall of the mounting groove 7. This allows the pressure frame 6 to be slid off, and subsequently the filter cloth body 9 to be removed. Afterwards, place the new filter cloth body 9 on the surface of the diaphragm plate 8 and insert the positioning block 5 into the inner wall of the positioning groove 4. The filter cloth body 9 can then be pressed by the pressure frame 6. The filter plate 2 is raised by the electric push rod 20, causing the lifting plate 28 and the fixing plate 29 to separate. The spring 12 returns to its original position and drives the mounting post 14 to be inserted into the inner wall of the mounting groove 7, thus limiting the installation of the pressure frame 6 and allowing the filter cloth body 9 to be installed. This achieves the purpose of facilitating quick replacement of the filter cloth body 9. The structure is simple and easy to use.
