[0035] See also Figure 7 and Figure 8 As shown, the stirring assembly includes a stirring rod 15, a contact plate 151, a return spring 152 and a spiral rod 153. Four stirring rods 15 are slidingly connected on the pressing block 10 at uniform intervals along the circumference. When the stirring rods 15 rotate, the stirring rods 15 can stir the rare earth waste. A contact plate 151 is fixed between the top ends of the four stirring rods 15. The contact plate 151 is located below the movable cylinder 9. Four return springs 152 are evenly spaced and connected between the bottom of the contact plate 151 and the top of the pressing block 10. The return spring 152 is sleeved on the stirring rod 15. The spiral rod 153 is rotatably connected to the middle of the top of the pressing block 10. A protrusion is provided on the lower left side of the movable cylinder 9. The protrusion of the movable cylinder 9 contacts the spiral groove of the spiral rod 153.

[0036] First, the reacted rare earth waste is poured into the feed frame 3, and the rare earth waste in the feed frame 3 is discharged into the cylinder 2 and blocked by the baffle plate 5. Then, the dual-axis motor 14 is started to rotate forward to drive the driving gear 141 to rotate forward, and the driving gear 141 rotates forward to drive the outer ring gear 142 to reverse, and the outer ring gear 142 reverses to drive the porous annular plate 4 to reverse, and the porous annular plate 4 reverses to drive the rare earth waste to rotate through the baffle plate 5. The rotation of the rare earth waste throws out the liquid through the centrifugal force, and the thrown liquid passes through the porous annular plate 4 and is discharged into the discharge frame 1. The liquid in the discharge frame 1 is discharged for collection. At the same time, the forward rotation of the dual-axis motor 14 also drives the screw 1 3 rotates forward, the screw rod 13 rotates forward to drive the movable cylinder 9 to move downward, the movable cylinder 9 moves downward and drives the pressing block 10 to move downward through the connecting spring 12, the pressing block 10 moves downward and contacts the rare earth waste, the pressing block 10 continuously moves downward to squeeze the rare earth waste, and also squeezes the liquid in the rare earth waste through the porous annular plate 4 and is discharged into the discharge frame 1, when the pressing block 10 compresses the rare earth waste to the maximum stroke, the pressing block 10 stops moving downward, the movable cylinder 9 continues to move downward to compress the connecting spring 12, the movable cylinder 9 drives the screw rod 153 to rotate, the rotation of the screw rod 153 drives the pressing block 10 to rotate, and the pressing block 1 0 rotates to drive the stirring rod 15 to rotate, and at the same time the movable cylinder 9 moves downward to contact the contact plate 151, the movable cylinder 9 drives the contact plate 151 to move downward, the reset spring 152 is compressed, the contact plate 151 moves downward to drive the stirring rod 15 to move downward, the stirring rod 15 moves downward and inserts into the rare earth waste, the stirring rod 15 rotates to stir the rare earth waste, and the position of the rare earth waste after stirring changes, becoming looser, so that the effect of the rare earth waste being squeezed again in the future is improved, and then the dual-axis motor 14 is started to reverse and drive the screw rod 13 to reverse, the screw rod 13 reverses and drives the movable cylinder 9 to move upward and reset, and the movable cylinder 9 is out of contact with the contact plate 151. Due to the action of the reset spring 152, the contact plate 151 is reset, driving the stirring rod 15 to move upward and reset. Due to the action of the connecting spring 12, the pressing block 10 does not move first, and the movable cylinder 9 moves upward to drive the spiral rod 153 to rotate in the opposite direction and reset. When the movable cylinder 9 moves upward to the maximum stroke of the spiral rod 153, the movable cylinder 9 drives the pressing block 10 to move upward and reset through the spiral rod 153. This is repeated, which can continuously make the pressing block 10 squeeze out the liquid in the rare earth waste in the cylinder body 2 to prevent the residual liquid in the rare earth waste from affecting subsequent use, thereby improving the effect of solid-liquid separation. When the solid-liquid separation of the rare earth waste is completed, the dual-axis motor 14 is turned off, the porous annular plate 4 stops rotating, the pressing block 10 stops moving up and down, and the telescopic rod of the electric push rod 51 is started to shorten and drive the limit block 52 to move outward and disengage from the baffle plate 5. Due to the weight of the rare earth waste, the rare earth waste drives the baffle plate 5 to swing downward and into an inclined state. The baffle plate 5 swings downward and drives the L-shaped block 53 to swing downward. The torsion spring 54 is compressed, and the rare earth waste falls from the baffle plate 5 and is collected. Due to the action of the torsion spring 54, the baffle plate 5 swings upward and resets, and then the electric push rod 51 is started to drive the limit block 52 to reset and continue to limit the baffle plate 5.

[0037] See also Figure 9 and Figure 10 As shown, it also includes a cleaning component installed between the dual-axis motor 14 and the discharge frame 1, the cleaning component includes a U-shaped rod 17, a hard brush 171, a movable plate 172, a straight hole plate 173 and a reciprocating component, the front middle of the feed frame 3 is slidably connected with a U-shaped rod 17, and a hard brush 171 is fixed between the two ends of the rear side of the U-shaped rod 17. The hard brush 171 contacts the porous annular plate 4. When the porous annular plate 4 rotates, the hard brush 171 can remove the rare earth waste attached to the porous annular plate 4. Two movable plates 172 are fixedly mounted on the rear side of the U-shaped rod 17. The two movable plates 172 are mounted on the top A flat orifice plate 173 is fixedly connected between the parts, and a reciprocating assembly is installed on the dual-axis motor 14. When the reciprocating assembly is in operation, the reciprocating assembly can drive the flat orifice plate 173 to move back and forth; the reciprocating assembly includes a disc 174 and a contact rod 175. The output shaft end below the dual-axis motor 14 is fixedly connected to the disc 174, and the disc 174 is located below the driving gear 141. The contact rod 175 is fixedly connected to the eccentric position of the bottom of the disc 174. The contact rod 175 is slidably connected to the inner side of the flat orifice plate 173. When the contact rod 175 rotates, the contact rod 175 can drive the flat orifice plate 173 to move back and forth.

[0038] When the dual-axis motor 14 is started, the dual-axis motor 14 drives the disc 174 to rotate, and the rotation of the disc 174 drives the contact rod 175 to rotate. The rotation of the contact rod 175 drives the straight hole plate 173 to move back and forth. The straight hole plate 173 moves back and forth, driving the movable plate 172 to move back and forth. The movable plate 172 moves back and forth and drives the bristle brush 171 to move back and forth. The bristle brush 171 moves back and forth to continuously remove the rare earth waste attached to the 4 holes of the porous annular plate. When the dual-axis motor 14 is turned off, the dual-axis motor 14 stops driving the disc 174 to rotate, the disc 174 stops driving the contact rod 175 to rotate, the contact rod 175 stops driving the straight hole plate 173 to move back and forth, the straight hole plate 173 stops driving the U-shaped rod 17 to move back and forth through the movable plate 172, and the U-shaped rod 17 stops driving the bristle brush 171 to move back and forth. In this way, the rare earth waste can be prevented from being adhered to and causing the porous annular plate 4 to be blocked, thereby affecting the solid-liquid separation, thereby improving the filtering effect of the porous annular plate 4 on the rare earth waste.

[0039] See also Figure 11 As shown, a filter plate 18 is also included. The filter plate 18 is symmetrically slidably connected to the front and rear lower right side of the discharge frame 1. The front and rear filter plates 18 are respectively in contact with the discharge ends on the front and rear sides of the discharge frame 1. When the liquid contacts the filter plate 18, the filter plate 18 can filter the rare earth waste doped in the liquid. Handles are fixed to the right sides of the front and rear filter plates 18.

[0040] When the liquid is discharged into the discharge frame 1, the liquid contacts the filter plate 18, the filter plate 18 filters the rare earth waste liquid mixed in the liquid, and the liquid after filtering the rare earth waste is discharged through the filter plate 18. When the filter plate 18 is filtered with a proper amount of rare earth, the handle is pulled to drive the filter plate 18 to move right. Due to the effect of the handle, the filter plate 18 can be better pulled to move right. The filter plate 18 moving right drives the rare earth waste to move right. The rare earth waste moving right is blocked by the discharge frame 1. When the filter plate 18 moving right is out of contact with the discharge frame 1, the filter plate 18 does not block the rare earth waste. The rare earth waste is discharged from the discharge frame 1, and then the filter plate 18 is pushed to move left to reset. In this way, the mixed rare earth waste can be further filtered and removed.
