The end of the return pipe 9 away from the water pump 8 is connected to the bottom of the connecting pipe 4. A bracket 10 is fixedly connected to the surface of the diversion pipe 5. The side of the bracket 10 away from the diversion pipe 5 extends to the top of the nozzle 7 and is movably connected to the nozzle 7 via a pin. A sleeve plate 11 is fixedly connected to the top of the nozzle 7 via a pin, and a connecting frame 12 is fixedly connected to the top of the diversion pipe 5. Inside the connecting frame 12, a bidirectional screw 13 is movably connected via bearings. Both sides of the surface of the bidirectional screw 13 are threaded with screw sleeves 14. Both sides of the bottom of the screw sleeves 14 are provided with inserts, the bottom ends of which extend into the interior of the sleeve plate 11 and are slidably connected to it. The inserts are bolts 15 located on both sides of the top of the screw sleeves 14. The bottom ends of the bolts 15 penetrate the screw sleeves 14 and extend into the interior of the sleeve plate 11, where they are slidably connected. Screw sleeves 14 are threaded together. A drive motor 16 is fixedly connected to one side of the connecting frame 12. The output end of the drive motor 16 penetrates the connecting frame 12 and is connected to the bidirectional screw. One end of the screw rod 13 is fixedly connected. A drain rod 17 is provided at the bottom of the connecting frame 12.

[0030] Specifically, during operation / use of this solid-liquid separation equipment for lithium battery recycled materials: the recycled material is first fed into the feed frame 3 at the top of the equipment. Simultaneously, nozzles 7 located on both sides of the feed frame 3 obtain flushing liquid from the distribution pipe 5 through hoses 6 and continuously spray it onto the material inside the feed frame 3. This flushing action is the first anti-clogging measure, attempting to disperse, dilute, and initially separate viscous materials, preventing them from clumping and accumulating at the inlet before entering the centrifuge. The water tank 2 located at the bottom of the equipment collects the liquid produced after centrifugal separation. The water pump 8 starts and draws liquid from the water tank 2. The liquid output by the water pump 8 is transported upward through the return pipe 9 and finally enters the connecting pipe 4. The liquid then flows upward from the connecting pipe 4 into the distribution pipe 5, and is then distributed to the hoses 6 and nozzles 7. This step realizes the recycling of the flushing liquid. When it is necessary to adjust the spray angle of the nozzle 7 to more effectively flush a specific area or adapt to materials of different viscosities, the drive motor 16 is operated. The drive motor 16 drives the bidirectional screw 13 to rotate within the connecting frame 12. The rotation of the bidirectional screw 13 causes the two screw sleeves 14 on its surface to move along the screw axis. The screw sleeves 14 are movably connected to the sleeve plate 11 on the top of the nozzle 7 through the plug-in connector. Therefore, the left and right movement of the screw sleeves 14 will drive the sleeve plate 11 to move. The sleeve plate 11 drives the nozzle 7 to swing around the pin axis, thereby changing the spray angle of the nozzle 7. During the movement of the screw sleeves 14, the crank 18 can also be used to squeeze the unblocking rod 17. The unblocking rod 17 is squeezed and moves vertically back and forth, which can further push the material inside the feed frame 3, thereby preventing the material from entering the obstruction.
