[0025] Specifically, the upper surface of the support 2 is symmetrically provided with a vertical disc 33, one end of the limiting column 3 is inserted into the corresponding vertical disc 33, the outer side of the vertical disc 33 is slidably provided with a fixed block 34, the outer side of the vertical disc 33 is provided with a sleeve block 36, the lower part of the fixed block 34 is clamped between the corresponding sleeve block 36 and the vertical disc 33, and the fixed block 34 is threadedly connected with one end of the corresponding limiting column 3 through a fixed bolt 35. The vertical disc 33 provides a basic structure for the insertion and fixation of the limiting column 3, ensuring the reliable connection of the limiting column 3 with the support 2. The fixed block 34 can slide on the outer side of the vertical disc 33, and the sleeve block 36 plays a role in auxiliary fixation and positioning. When the limiting column 3 needs to be installed, the limiting column 3 is inserted into the vertical disc 33, the fixed block 34 is slid to clamp its lower part between the sleeve block 36 and the vertical disc 33, and then the fixed block 34 is threadedly connected with the limiting column 3 through the fixed bolt 35, so as to realize the firm fixation of the limiting column 3. When disassembling, the fixed bolt 35 is unscrewed, and the limiting column 3 can be taken out by sliding the fixed block 34, which facilitates the installation, disassembly and maintenance of the filter plate. Moreover, the detachable structure facilitates the replacement of the limiting column 3 when it is damaged.

[0026] It is worth noting that the lower surface of the support 2 is symmetrically provided with a support rod 41, and a rotating column 42 is rotatably arranged between the two support rods 41. The outer side of the support rod 41 on one side is fixedly provided with a motor 43, and the output end of the motor 43 penetrates the support rod 41 and is fixedly connected with the corresponding rotating column 42. The outer surface of the rotating column 42 is symmetrically provided with a convex disc 44, and the outer surface of the convex disc 44 is movably attached to the corresponding lifting plate 4. The upper surface of the lifting plate 4 is symmetrically provided with a vertical rod 45, and the upper end of the vertical rod 45 is fixedly provided with a tray 46. The upper surface of the tray 46 is movably attached to the corresponding limiting column 3. After the motor 43 is started, the output power drives the rotating column 42 to rotate, and the convex disc 44 fixedly sleeved on the outer surface of the rotating column 42 rotates accordingly. Since the outer surface of the convex disc 44 is movably attached to the lifting plate 4, and the shape of the convex disc 44 is irregular (cam-shaped), during the rotation process, the convex disc 44 will generate an upward or downward thrust on the lifting plate 4, thereby causing the lifting plate 4 to move up and down along the direction of the support rod 41. The vertical rod 45 and the tray 46 on the lifting plate 4 are movably attached to the limiting column 3. When the lifting plate 4 moves up and down, the tray 46 pushes the limiting column 3 to move up and down, thereby driving the plate body 1 cooperating with the limiting column 3 to adjust the height or generate vibration. During the unloading stage after the filter press completes the filter pressing, the motor 43 drives the lifting plate 4 to drive the plate body 1 to vibrate, which can promote the separation of the filter cake and the filter cloth, thereby improving the unloading efficiency.

[0027] It is worth noting that the upper surface of the support 2 is symmetrically provided with a through groove 48 matched with the vertical rod 45, both sides of the through groove 48 are symmetrically provided with a sliding groove 49, both sides of the vertical rod 45 are symmetrically provided with a sliding plate 47, and the sliding plate 47 is clamped in the corresponding sliding groove 49, the through groove 48 provides space for the vertical rod 45 to move up and down, the sliding groove 49 cooperates with the sliding plate 47 on both sides of the vertical rod 45 to play a guiding and limiting role, when the lifting plate 4 moves up and down under the pushing of the convex disc 44, the sliding plate 47 on the vertical rod 45 slides in the sliding groove 49, ensuring that the lifting plate 4 moves stably up and down, avoiding deviation or shaking, ensuring the stability and reliability of the entire lifting structure, and further making the height adjustment and shaking process of the plate body 1 more stable and accurate.

[0028] Wherein, the liquid outlet faucet 12 and the motor 43 are prior art, and will not be described again; meanwhile, the utility model also includes a power supply, a controller and a switch, which are not the main technical points of the patent, and will not be described again; the "front, rear, left and right" visual angle of the device is taken as the reference direction of the drawing. Figure 1

[0029] Working principle: when the ultra-high pressure diaphragm filter press filter plate starts to work, in the filtration stage, the slurry enters the filter chamber composed of the plate body 1 and the filter cloth under the action of pressure, the filtrate is discharged through the filter cloth, and the solid particles gradually form filter cake on the surface of the filter cloth; when the filtration is completed and enters the extrusion stage, high-pressure fluid is introduced into the diaphragm, and the diaphragm expands to extrude and dewater the filter cake;

[0030] After the filter press completes the pressure filtration, the motor 43 is started to drive the rotating column 42 to rotate, and the convex disc 44 fixedly sleeved on the outer surface of the rotating column 42 rotates, since the convex disc 44 is movably attached to the lifting plate 4, during the rotation of the convex disc 44, the irregular outer contour of the convex disc 44 will generate upward or downward thrust on the lifting plate 4, so that the lifting plate 4 reciprocates along the direction of the supporting rod 41 of the lower surface of the support 2, the sliding plate 47 fixed on both sides of the vertical rod 45 on the upper surface of the lifting plate 4 cooperates with the sliding groove 49 on both sides of the through groove 48, ensuring that the lifting plate 4 moves stably up and down, avoiding deviation;

[0031] Periodic shaking prevents local blockage of the filter cloth, maintains stable air permeability of the filter cloth, reduces the number of frequent cleaning of the filter cloth due to blockage, reduces the degree of wear of the filter cloth, prolongs the replacement cycle of the filter cloth, compared with the traditional filter plate, the service life of the filter cloth can be prolonged by about 40%, effectively reducing the equipment operation cost;

[0032] ​When the lifting plate 4 moves, the tray 46 on the lifting plate 4 drives the limiting column 3 to move up and down, the limiting column 3 is inserted into the vertical disc 33 on the upper surface of the support 2 at one end, is fixed through the sleeve block 36, the fixed block 34 and the fixed bolt 35, and is movably penetrated into the movable slot 32 of the limiting block 31 in the limiting frame 11 at the other end, with the up and down movement of the limiting column 3, the plate body 1 connected with the limiting frame 11 through the bolt is driven to shake up and down, in the unloading stage, the shaking of the plate body 1 promotes the relative displacement of the filter cake and the filter cloth, reduces the adhesion between them, makes the filter cake more easily fall off, and completes the unloading process, and the liquid outlet faucet 12 on both sides of the plate body 1 is responsible for guiding the filtrate out during the filtering process, and ensures that the filter pressing work is carried out smoothly.
