DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: like Figure 1-9 As shown, this embodiment provides a plate-and-frame filter press with fast filter plate unloading, comprising a frame 10, on which a plurality of groups of material plates 11 are arranged; The frame 10 is provided with two groups of symmetrically arranged moving rails 40, the moving rails 40 are provided with a moving shell 30, the moving shell 30 is provided with two groups of elastic limiting components 20, and the moving rails 40 are provided with multiple groups of guiding protruding hemispheres 41. The moving shell 30 is displaced on the moving rails 40 so that the material plate 11 is placed between the two groups of elastic limiting components 20. The elastic limiting components 20 are in contact with the guiding protruding hemispheres 41 to generate vibration, so that the material plate 11 between the two groups of elastic limiting components 20 shakes.

[0019] In this embodiment, when the material sheet 11 is unloaded, the movable housing 30 is displaced on the movable rail 40, so that the ear plates on both sides of the material sheet 11 are disposed between the two sets of elastic limit assemblies 20, and the material sheet 11 is driven to displace along the long side direction of the movable rail 40 by the two sets of movable housings 30. During the displacement process, the elastic limit assemblies 20 contact the guide protruding hemispheres 41 and generate vibrations. At the same time, the vibrations are transmitted to the material sheet 11 through the movable housing 30 and the elastic limit assemblies 20, so that the mud cake on the surface of the material sheet 11 is accelerated to detach; The cooperation between the elastic limiting assembly 20 and the guiding protruding hemisphere 41 achieves the technical effect of generating vibration during the material sheet 11 unloading process. The vibration is generated by the contact between the elastic limiting assembly 20 and the guiding protruding hemisphere 41 and is effectively transmitted to the material sheet 11, thereby accelerating the separation of the mud cake from the surface of the material sheet 11, improving the unloading efficiency and the mud cake separation effect. Vibration is generated by the cooperation between the elastic limit assembly 20 and the guide protruding hemispherical body 41, and no additional manual tapping of the material plate 11 is required, which reduces manual intervention, reduces labor intensity, improves production safety, and can also greatly improve production efficiency; Vibration is generated by the cooperation between the elastic limiting component 20 and the guiding protruding hemispherical body 41, and the speed of mud cake discharge can be accelerated during the displacement of the material plate 11, without requiring additional processing time, which can further reduce time cost.

[0020] Specifically, the elastic limiting assembly 20 includes a swing rod 23, and a swing plate 24 is provided on the swing rod 23; The swing rod 23 is connected to the moving housing 30 , and two groups of guiding arc surfaces 25 are symmetrically arranged on the swing plate 24 .

[0021] Specifically, the movable housing 30 includes a top movable block 32, and two sets of movable grooves 34 are formed on the top movable block 32; The swing rod 23 is provided with a limit movable rod 22 , which is rotatably provided on the swing rod 23 , and both ends of the limit movable rod 22 are provided with movable mounting plates 21 , which are provided at the movable groove 34 .

[0022] In this embodiment, when the material plate 11 is driven to move, the movable housing 30 moves toward the material plate 11, so that the swing plate 24 close to the material plate 11 first contacts the ear plate of the material plate 11, and the ear plate squeezes the swing plate 24, so that the swing plate 24 rotates and descends about the axis of the limit movable rod 22, so that the swing plate 24 moves when the ear plate is lowered, and when the swing plate 24 close to the material plate 11 passes under the ear plate, the swing plate 24 is reset, so that the ear plate of the material plate 11 is placed between the two sets of swing plates 24, and then the movable housing 30 moves, driving the material plate 11 to move; Of course, the provided guiding arc surface 25 can facilitate the displacement of the ear plate to the top of the swing plate 24, exert a downward pressure on the swing plate 24, and facilitate the axis of the swing plate 24 to rotate and descend.

[0023] Specifically, the top moving block 32 is provided with a swing cavity 323 , and the swing cavity 323 is connected to the movable groove 34 . The swing rod 23 takes the axis of the limiting movable rod 22 as the swing center, and moves back and forth in the swing cavity 323 to generate vibration.

[0024] Specifically, a mounting groove 324 is formed on the top moving block 32, and the mounting groove 324 is connected to the swing cavity 323; A return spring 26 is disposed in the mounting groove 324 . The return spring 26 is connected to the inner wall of the side end of the mounting groove 324 . The return spring 26 is also connected to the swing rod 23 .

[0025] In this embodiment, when the movable housing 30 drives the material plate 11 to move, the swing rod 23 contacts the guide protruding hemisphere 41, so that the swing rod 23 rotates and swings around the axis of the limit movable rod 22, thereby stretching the reset spring 26. When the swing rod 23 is not in contact with the guide protruding hemisphere 41, the reset spring 26 resets and drives the swing rod 23 to reset. By continuously contacting the guide protruding hemisphere 41, vibration is generated to facilitate rapid material unloading. Of course, when the swing rod 23 rotates and swings around the axis of the limiting movable rod 22 and stretches the reset spring 26, the swing plate 24 will move toward the other set of swing plates 24, thereby pressing against the ear plate of the material plate 11 and accelerating the material plate 11 forward for a certain distance. By continuously accelerating and pushing, the material unloading speed can be further increased.

[0026] Specifically, the movable housing 30 further includes two sets of side plates 31, a bottom movable block 33 is disposed between the two sets of side plates 31, and the bottom movable block 33 is symmetrically disposed with the top movable block 32; Two groups of moving wheels 311 are disposed on the side plates 31 , and the moving wheels 311 are in contact with the moving rails 40 , so that the two groups of side plates 31 , a group of bottom moving blocks 33 and a group of top moving blocks 32 are displaced on the moving rails 40 .

[0027] Specifically, the side panel 31 is provided with four sets of side panel mounting holes 314; Two groups of bottom mounting holes 331 are symmetrically arranged on the bottom moving block 33, and two groups of top mounting holes 321 are symmetrically arranged on the top moving block 32. The positions of the two groups of bottom mounting holes 331 and the two groups of top mounting holes 321 match the positions of the four groups of side panel mounting holes 314. The bottom mounting holes 331 are connected to the side panel mounting holes 314 by bolts, and the top mounting holes 321 are connected to the side panel mounting holes 314 by bolts.

[0028] In this embodiment, the two sets of side plates 31 cooperate with the top moving block 32 and the bottom moving block 33 to enable the moving housing 30 to be modularly divided, which can facilitate subsequent maintenance.

[0029] Specifically, two groups of moving grooves 322 are formed on the top moving block 32, the moving wheels 311 are rotatably disposed in the moving grooves 322, and the swing cavity 323 is disposed between the two groups of moving wheels 311; A driving slot 332 is formed on the bottom moving block 33 , and a driving gear 312 is disposed between the two sets of side plates 31 . The driving gear 312 is rotatably disposed in the driving slot 332 .

[0030] Specifically, a rack 42 is provided at the bottom of the movable rail 40, and the driving gear 312 is meshed with the rack 42; A driving servo motor 313 is disposed on the side plate 31 . The driving servo motor 313 is in driving connection with a driving gear 312 . The driving servo motor 313 is disposed on a group of side plates 31 away from the material plate 11 .

[0031] In this embodiment, through the cooperation between the driving gear 312 and the rack 42 , when the driving gear 312 rotates, it can effectively drive the bottom moving block 33 to move, thereby driving the entire moving housing 30 to move on the moving rail 40 .

[0032] A plate-and-frame filter press with fast filter plate unloading is easy to use and comprises the following steps: S10, one-time installation: Place two sets of side plates 31 on both sides of the moving rail 40, and place the top moving block 32 between the two sets of side plates 31, and install them by bolts; S20, one test: Manually press down the top moving block 32, and push the top moving block 32 to move on the moving rail 40, and observe whether the guiding protruding hemisphere 41 can drive the swing rod 23 to swing in the swing cavity 323. If not, repeat S10 to replace the top moving block 32 until the swing rod 23 contacts the guiding protruding hemisphere 41 and the swing rod 23 can swing in the swing cavity 323. S30, Secondary test: The driving servo motor 313 is turned on to drive the driving gear 312 to rotate, and it is observed whether the driving gear 312 can drive the movable housing 30 to move back and forth on the movable rail 40. If it cannot move back and forth, the side plate 31 containing the driving servo motor 313 is replaced until the driving servo motor 313 is turned on and the driving gear 312 can drive the movable housing 30 to move back and forth on the movable rail 40.
