After processing the power battery, the drive motor 12 pushes the movable push plate 15 to move in the disassembly tank 11 through the telescopic rod 14. The movement of the movable push plate 15 can drive the electrolyte to flow along the drainage groove 17 to the partition panel 18, and flow out of the disassembly tank 11 from the discharge port 19 into the transfer pipe 34, and finally enter the main discharge pipe 36 for centralized discharge. Some electrolyte remaining on the surface of the parts can flow into the main discharge pipe 36 through the receiving pool 37 from the infiltration hole 33 under the action of gravity.
