[0022] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in Pulley assemblies are arranged on both sides of the filter press plate 2; Separation units are symmetrically arranged on both sides of the filter press frame 1, including: A lead screw assembly arranged on the side of the filter press frame 1; The poking rod assembly 3 and the knocking assembly 4 arranged on the lead screw assembly; The lever assembly 3 includes: A hydraulic cylinder 31 fixed on the upper side of the lead screw assembly; A support block 32 fixedly connected to the piston rod end of the hydraulic cylinder 31; A guide hole 321 is formed in the support block 32, and a slider 322 is slidably arranged therein; One side of the slider 322 close to the filter press plate 2 is fixedly connected with a support plate 33 and a bar 331; the other side is fixedly connected with a mounting block 34; An electronic force measuring instrument 35 is arranged on the support block 32, and a force measuring spring 351 at the bottom of the electronic force measuring instrument 35 is connected to the mounting block 34; Among them: The hydraulic cylinder 31 drives the support block 32 to slowly jack up the filter press plate 2 and then quickly reset, so that the filter press plate 2 falls back to generate a vertical impact; The knocking assembly 4 applies a horizontal knock during the jacking up and falling back processes of the filter press plate 2, forming a synergistic vibration effect with the vertical impact to peel off the filter residue; During jacking up, the acting force is transmitted through the force measuring spring 351, and the electronic force measuring instrument 35 judges the quality of the remaining filter residue by monitoring the weight.

[0023] In this embodiment, after the filter pressing process is completed, in the initial state, the lead screw assembly drives the separation unit to move to the position of the target filter press plate 2; at this time, the hydraulic cylinder 31 is started, and its piston rod is pushed to slowly jack up the support block 32, and the bar 331 is inserted into the side of the pulley assembly of the filter press plate 2, and then this filter press plate 2 is separated through the lead screw assembly; then, the support block 32 transmits the acting force to the filter press plate 2 through the support plate 33, overcoming the friction force between the pulley assembly and the filter press frame 1, and the filter press plate 2 is then jacked up uniformly upward; during this jacking up process, the knocking assembly 4 simultaneously starts to continuously apply a reciprocating knocking force in the horizontal direction to the side of the filter press plate 2; when the filter press plate 2 is jacked up to a predetermined height and remains stable, the electronic force measuring instrument 35 calculates the total weight of the jacked-up filter press plate 2 by measuring the deformation of the force measuring spring 351, and judges the filter residue peeling requirement accordingly; then, the hydraulic cylinder 31 makes its piston rod quickly reset, driving the support block 32 to rapidly descend; the support plate 33 and the bar 331 of the support block 32 are instantly separated from the support of the filter press plate 2, and the filter press plate 2 freely falls back under its own gravity, and its pulley assembly impacts the filter press frame 1 to generate a vertical impact to shake off the filter residue; during the entire falling back process, the horizontal knocking applied by the knocking assembly 4 is carried out synchronously, and the synergistic vibration effect acts on the filter press plate 2 jointly, efficiently destroying the adhesion between the highly viscous filter residue and the surface of the filter press plate 2, and promoting its effective peeling; as the hydraulic cylinder 31 is completely reset, the filter press plate 2 falls back to its original position; after the filter press plate 2 is stable, the filter press plate 2 is jacked up again, and the electronic force measuring instrument 35 can judge the peeling effect of the remaining filter residue according to the weight, so as to determine whether another peeling operation is required; repeating the above steps can realize the piece-by-piece separation, slag discharging and monitoring of each filter press plate 2, and the whole process can be completed automatically.

[0024] Preferably, the lead screw assembly includes a drive motor 114 fixed to the end of the filter press frame 1. The output end of the drive motor 114 is connected to a lead screw 111. A moving block 112 is screwed onto the lead screw 111. On the side of the moving block 112 close to the filter press frame 1, a sliding plate is fixedly connected. The sliding plate is slidably engaged with the filter press frame 1. The bottom end of the hydraulic cylinder 31 is fixed to the top of the moving block 112. The lower hanging plate 41 is fixed to the bottom of the moving block 112. After the filter press process ends, the drive motor 114 fixed to the end of the filter press frame 1 starts, and its output end drives the lead screw 111 to rotate. The rotation of the lead screw 111 causes the moving block 112 screwed onto it to generate an axial displacement. On the side of the moving block 112 close to the filter press frame 1, a sliding plate is fixed. The sliding plate is slidably engaged with the guiding structure on the filter press frame 1, effectively restricting the moving direction of the moving block 112, preventing it from rotating with the lead screw 111, and ensuring that it can only translate along a predetermined straight path.

[0025] Preferably, the knocking assembly 4 includes a lower hanging plate 41 fixed to the bottom of the lead screw assembly. On the side of the lower hanging plate 41 close to the filter press frame 1, a cross bar 44 is fixed. At the other end of the cross bar 44, a side plate 45 is fixed. A sliding rod 46 is slidably arranged on the side plate 45. At the end of the sliding rod 46 close to the filter press frame 1, a knocking head 48 is arranged. On the lower hanging plate 41, a driving part is arranged for driving the sliding rod 46 to move reciprocally. The driving part includes a rotating rod 42 arranged on the lower hanging plate 41. At one end of the rotating rod 42 close to the sliding rod 46, an eccentric wheel 43 is arranged. At one end of the sliding rod 46 close to the eccentric wheel 43, an arc-shaped pressure receiving plate 47 is fixed. A return spring 471 is connected between the pressure receiving plate 47 and the side plate 45. The return spring 471 is sleeved on the sliding rod 46. On the lower hanging plate 41, a triggering assembly is arranged for triggering the rotation of the rotating rod 42. The triggering assembly includes a driven gear 424 arranged at the other end of the rotating rod 42, and a toothed plate 49 meshing with the driven gear 424. The top end of the toothed plate 49 is fixedly connected to the support block 32. When the hydraulic cylinder 31 drives the support block 32 to move, the support block 32 drives the driven gear 424 to rotate through the toothed plate 49, and then drives the eccentric wheel 43 to perform an eccentric motion to drive the sliding rod 46 to move reciprocally.

[0026] In this implementation process, the driving motor 114 starts, driving the lead screw 111 to rotate, driving the screwed moving block 112 to move axially along the filter press frame 1. The sliding plate on the side of the moving block 112 is slidably matched with the filter press frame 1 to ensure linear displacement; synchronously driving the hydraulic cylinder 31, the lever assembly 3 fixed on the top of the moving block 112, and the knocking assembly 4 fixed on the bottom of the moving block 112 to translate as a whole until the support plate 33 of the lever assembly 3 and the knocking head 48 of the knocking assembly 4 are positioned at the target filter plate 2; subsequently, the piston rod of the hydraulic cylinder 31 slowly extends, driving the supporting block 32 and the toothed plate 49 fixed thereon to slowly rise synchronously. The supporting block 32 drives the support plate 33 to lift the filter plate 2 to lift it from the original support position. During this process, the jacking force is transmitted to the force-measuring spring 351 through the slider 322 and the mounting block 34, and the electronic force-measuring instrument 35 monitors the total weight of the filter plate 2 and the residual filter residue in real time; during the jacking process, the toothed plate 49 rises to mesh with the driven gear 424, causing the eccentric wheel 43 to rotate and driving the knocking head 48 to reciprocally strike the filter plate 2, loosening the filter residue adhered to the filter plate 2; after the jacking is in place, the piston rod of the hydraulic cylinder 31 rapidly contracts, driving the supporting block 32 and the toothed plate 49 to rapidly descend. The support plate 33 disengages from the filter plate 2, causing it to freely fall, and the pulley 22 impacts the filter press frame 1 to generate impact vibration to peel off the filter residue; synchronously, the descending toothed plate 49 reversely meshes to drive the driven gear 424 to reverse, driving the rotating rod 42 and the eccentric wheel 43 to rotate. The eccentric wheel 43 forces the sliding rod 46 to reciprocally rush forward against the resistance of the return spring 471 through the arc-shaped pressure-receiving plate 47, reciprocally driving the knocking head 48 to strike the side of the filter plate 2. This knocking vibration and the aforementioned falling impact act synergistically to shake off the adhered filter residue; the fallen filter residue is collected by the material receiving hopper 13, and the data of the electronic force-measuring instrument 35 is used to judge the residual amount and decide to repeat the operation; the device moves plate by plate in a cycle.

[0027] Preferably, the rotating rod 42 includes a fixed cylinder 421 fixed to the lower hanging plate 41 and a rotating round rod 422 rotatably arranged on the lower hanging plate 41. One end of the rotating round rod 422 is connected to the eccentric part of the eccentric wheel 43, and the other end is connected to the driven gear 424. A coil spring 423 is arranged in the fixed cylinder 421. One end of the coil spring 423 is connected to the inner wall of the fixed cylinder 421, and the other end is connected to the outer circumference of the rotating round rod 422; when the hydraulic cylinder 31 is reset, the rack on the toothed plate 49 is located below the driven gear 424; when the hydraulic cylinder 31 drives the supporting block 32 to lift the filter plate 2, the rack on the toothed plate 49 is located above the driven gear 424; The piston rod of the hydraulic cylinder 31 extends slowly, driving the supporting block 32 and the toothed plate 49 fixed on it to rise; the toothed plate 49 moves upward from the lower side of the driven gear 424 and meshes with and drives the driven gear 424, driving the rotating round rod 422 to rotate positively relative to the fixed cylinder 421, and at the same time twisting and storing energy in the coil spring 423 in the fixed cylinder 421. During the jacking process, the rotating round rod 422 will drive the eccentric wheel 43 to rotate to drive the knocking head to knock on the filter pressing plate 2, loosening the filter residue adhered to the filter pressing plate 2; after jacking in place, the rack on the toothed plate 49 moves out of the driven gear 424. After the stored energy of the coil spring 423 is released, it first drives the rotating round rod 422 and the eccentric wheel 43 to rotate, driving the knocking head 48 to repeatedly impact the side of the filter pressing plate 2, extending the knocking time; after the potential energy of the coil spring 423 is released, the filter pressing plate 2 is kept stable and then the data of the electronic force measuring instrument 35 is recorded to ensure the accuracy of the data; then, the hydraulic cylinder 31 resets, and the piston rod of the hydraulic cylinder 31 contracts rapidly, driving the supporting block 32 and the toothed plate 49 to descend rapidly. During this process, the toothed plate 49 meshes with the driven gear 424 again to drive the knocking head to knock on the filter pressing plate 2; when the toothed plate 49 descends to the lower side of the driven gear 424 and disengages from the meshing instantaneously, the stored coil spring 423 releases its elastic potential energy, driving the rotating round rod 422 to rotate reversely, driving the eccentric wheel 43 to impact the pressure receiving plate 47 of the sliding rod 46, forcing the knocking head 48 to repeatedly impact the side of the filter pressing plate 2, so that the filter pressing plate 2 can be continuously knocked by the knocking head 48 during the falling process; synchronously, the unsupported filter pressing plate 2 falls downward and impacts the filter pressing frame 1, forming a cooperative peeling with the lateral knocking.

[0028] Preferably, the sliding rod 46 includes an outer rod 461 slidably arranged with the side plate 45. An inner rod 462 is slidably arranged in the outer rod 461. The knocking head 48 is fixed at the end of the inner rod 462 close to the filter pressing frame 1. A first spring 463 is connected between the knocking head 48 and the outer rod 461, and the first spring 463 is sleeved on the inner rod 462; The inner rod 462 can slide in the outer rod 461, enabling the sliding rod 46 to expand and contract to meet the knocking requirements of filter pressing plates 2 of different sizes.

[0029] Preferably, the pulley assembly includes an L-shaped side support 21. A pulley 22 is fixed at the bottom of the side support 21. A clamping block 113 adapted to the pulley 22 is arranged on the filter pressing frame 1 to limit the moving route of the pulley 22.

[0030] Preferably, the filter pressing frame 1 includes two groups of supporting beams 11 for supporting both sides of the filter pressing plate 2. An infusion pipe for infusing liquid into the filter pressing part composed of the filter pressing plates 2 is arranged in the supporting beam 11. Columns 12 are symmetrically arranged at both ends of the bottom of the supporting beam 11. A receiving hopper 13 for receiving materials is fixed between the columns 12; During the feed filter press stage, the slurry is injected into the filter press chamber formed by multiple groups of filter press plates 2 through the infusion pipe embedded in the support beam 11. The hydraulic system on the filter press frame 1 drives the filter press plates 2 to press and separate the solid and liquid, and the filtrate is discharged, and the filter residue is retained on the surface of the filter cloth.

[0031] Preferably, the horizontal knocking of the knocking assembly 4 and the vertical impact of the lever assembly 3 are performed synchronously in time; when the hydraulic cylinder 31 drives the support block 32 to quickly reset, the descending action of the support block 32 synchronously triggers the horizontal knocking of the knocking assembly 4, and the duration of the horizontal knocking covers the entire falling process of the filter press plate 2.

[0032] Working principle: When in use, after the filtration is completed, the driving motor 114 drives the screw rod 111 to rotate, driving the screw-connected moving block 112 and the hydraulic cylinder 31 on its top, the lever assembly 3 and the knocking assembly 4 at the bottom to synchronously translate axially along the filter press frame 1 and position it below the target filter press plate 2; the piston rod of the hydraulic cylinder 31 slowly rises, driving the support block 32 to drive the support plate 33 and the lever 331 to move upward, first the lever 331 drives the side support 21 to separate the adjacent filter press plates 2, and then the support plate 33 lifts the L-shaped side support 21 to lift the filter press plate 2 off the support plate Beam 11; during this process, the lifting force is transmitted to the force measuring spring 351 through the slider 322, and the electronic force gauge 35 monitors the weight of the filter press plate 2 containing residue in real time; after the lifting is in place, the hydraulic cylinder 31 drops rapidly, and the filter press plate 2 falls freely to produce a vertical impact. At the same time, the tooth plate 49 disengages and triggers the coil spring 423 to release energy, driving the eccentric wheel 43 to hit the side of the filter press plate 2 at high speed, forming a vertical impact and horizontal high-frequency knocking composite vibration to strip the filter residue; the electronic force gauge 35 compares the residual amount and decides to repeat the stripping, and the cycle is completed until all the filter press plates 2 are processed.
