[0002] Electroplating solution recycling technology mainly processes the used electroplating solution to recover its valuable components, reduce environmental pollution and achieve resource recycling.

[0003] In the process of recovering the electroplating solution, it is usually necessary to add a precipitant to the electroplating solution to make the metal ions in the electroplating solution form an insoluble precipitate. After adding the precipitant, the electroplating solution usually needs to be stirred.

[0011] Preferably, a toothed plate is fixedly connected to the inner wall of the rear end of the recovery groove, and the toothed plate is meshed with the top end of the pulley three.

[0012] A method for recovering electroplating liquid in an electroplating tank, used in the aforementioned system for recovering electroplating liquid in an electroplating tank, comprises the following steps: Step 1: introduce the electroplating solution into the recovery tank, and then pour the prepared sedimentation agent into the sedimentation agent box, rotate the screw rod to move the pulley 3, and the pulley 3 is meshed with the tooth plate while moving, so as to realize the rotation of the stirring blade to stir the electroplating solution; Step 2: Wind up the rack by the winding column. When the moving block moves the rack, gear 1 and pulley 1 can rotate. Then gear 1 drives the auger to transport the sediment to the filter plate. The sediment can be filtered through the filter plate, and the electroplating liquid returns to the recovery tank. Pulley 1 drives pulley 2 to rotate, so that pulley 2 lifts the connecting rod, and the connecting rod can be reset by spring 1, thereby realizing the up and down movement of the front end of the filter plate to achieve the vibration effect on the filter plate.

[0013] Preferably, the screw in step one is driven by a motor, and the non-driving end of the motor is connected to the recovery groove. When the pulley three rotates by meshing with the tooth plate, the pulley four is rotated through the belt. The pulley four rotates the connecting cylinder at the bottom, and the connecting cylinder rotates the connecting disk at its bottom. The connecting disk stirs the electroplating liquid with the stirring blades on its outer wall, and the connecting disk is threadedly connected to the reciprocating screw. When the connecting disk rotates, the reciprocating screw moves up and down, and then the movable disk moves up and down to disperse the precipitate in the center.

[0014] Preferably, the winding column in the step 2 is rotated by a clockwork spring, thereby realizing the winding of the rack. When winding, the side of the rack meshing with the gear one pushes the teeth of the gear one and the outer wall of the pulley one to rotate in the rotating groove, so that the gear one and the pulley one cannot be rotated when the rack moves. On the contrary, the teeth can be reset by spring two, so that the teeth of the gear one and the outer wall of the pulley one can mesh with the rack, thereby realizing that the rack can drive the gear one and the pulley one to rotate. The rotation of the gear one drives the auger to transport the sediment to the filter plate. The rotation of pulley one drives the pulley two to rotate through the belt, so that the slope at the top of the pulley two lifts the connecting rod, and the connecting rod is reset by spring one, thereby realizing the vibration of the front end of the filter plate, which is convenient for the sediment to move to the position of the discharge port.

[0015] Working principle: First, the plating liquid is introduced into the recovery tank through the liquid inlet pipe, and then the prepared sedimentation agent is poured into the sedimentation agent box, and the screw is driven by the motor to rotate. When the screw rotates, it can move the moving block, so that the moving block moves with the pulley three at the rear side of the bottom end. When the pulley three moves, the top side of the pulley three meshes with the tooth plate, so that the pulley three rotates, and then the pulley three rotates with the pulley four through the belt, and the pulley four rotates with the connecting tube at its bottom, and the connecting tube rotates with the connecting tube at its bottom. The receiving plate rotates, and the stirring blades rotate through the connecting plate to stir the electroplating liquid, so that the sedimentation agent is evenly dispersed in the electroplating liquid, thereby improving the efficiency of the precipitation reaction and avoiding the occurrence of incomplete local precipitation reaction. When the moving plate rotates, the reciprocating screw rod moves up and down, and the top of the reciprocating screw rod is fixedly connected to the moving column, so that the top of the moving column slides up and down inside the fixed column, and the bottom end of the moving column slides inside the connecting tube, thereby driving the moving plate at the bottom end of the reciprocating screw rod to move up and down, so as to avoid the sediment from accumulating in the center of the vortex generated by the stirring of the electroplating liquid. When the moving block moves to the left, the moving block can move with the rack. At this time, the rack can drive the gear 1 and the pulley 1 to rotate. The rotation of the gear 1 can drive the auger to rotate, so as to transport the sediment to the filter plate, and filter the sediment through the filter plate, so that the electroplating liquid in the sediment flows back into the recovery tank. The rotation of the pulley 1 can drive the pulley 2 to rotate through the belt, so as to lift the bottom side of the right end of the connecting rod through the slope on the pulley 2, and reset the connecting rod through the spring 1, so as to achieve The connecting rod moves up and down, and moves the front end of the filter plate up and down through the bottom side of the left end of the connecting rod to achieve a vibration effect on the filter plate, so that the sediment on the filter plate is vibrated to the front end of the filter plate, i.e., near the discharge port, to facilitate the collection of the sediment; when the moving block moves to the right, the clockwork spring winds up the rack through the winding column, so that the side of the rack meshing with gear one pushes the teeth of the outer wall of gear one and pulley one into the rotating groove, so that in the process of winding up the rack, gear one and pulley one cannot be rotated by the rack.

[0016] The present application provides a system and method for recovering electroplating liquid in an electroplating tank, which has the following beneficial effects: 1. The present application can move the moving block by driving the screw to rotate through a motor. When the moving block moves, the moving belt pulley three is meshed with the toothed plate to rotate the pulley three, and then the pulley three rotates the pulley four through the belt, thereby realizing the rotation of the stirring blade to stir the electroplating liquid in the recovery tank, so that the sedimentation agent is evenly dispersed in the electroplating liquid to avoid incomplete precipitation reaction in the electroplating liquid. While the moving disk rotates, the reciprocating screw rod moves up and down, and the top end of the reciprocating screw rod is fixedly connected to the moving column, so that the top end of the moving column slides up and down inside the fixed column, and the bottom end of the moving column slides inside the connecting tube, thereby driving the moving disk at the bottom end of the reciprocating screw rod to move up and down, to avoid the sediment from accumulating in the center of the vortex generated by the stirring of the electroplating liquid.

[0017] 2. The present application drives the gear 1 and the pulley 1 to rotate by the moving block driving the rack, and the gear 1 drives the auger to rotate, so as to transport the sediment flowing to the right side of the recovery tank to the filter plate, and drives the pulley 2 to rotate through the pulley 1, so that the pulley 2 can lift the connecting rod, and then the connecting rod drives the front end of the filter plate to move, so as to achieve the vibration effect of the filter plate, avoid the sediment transported to the filter plate by the auger to accumulate on the filter plate, thereby affecting the filtering efficiency of the filter plate, and through the vibrating filter plate, the sediment on the filter plate can be vibrated to the discharge port, so as to facilitate the staff to collect the sediment.

[0018] 3. The present application can achieve stirring of the electroplating solution, transport of the precipitate to the filter plate and vibration of the filter plate through a single motor, so that multiple steps can be performed simultaneously, greatly improving the efficiency of the use of the device and the efficiency of electroplating solution treatment.
