Cleaning device and method for lithium battery graphite negative plate recovery

The cleaning device comprises a cleaning water tank, a conveying net chain is installed in the cleaning water tank, and a first cross-shaped stirring wheel, a second cross-shaped stirring wheel and a third cross-shaped stirring wheel which rotate are installed in the cleaning water tank and located above the conveying net chain. And the first cross-shaped stirring wheel, the second cross-shaped stirring wheel and the third cross-shaped stirring wheel are respectively driven by three independent rotating motors. According to the method, in the cleaning process, the pole pieces in the cleaning water tank are continuously moved, the moving pole pieces are continuously stirred by the stirring wheels and generate friction with the conveying net chain, so that graphite falls off and sinks to the position below the conveying net chain, and the cleaned copper foil is left above the net chain, and according to the method, each pole piece is uniformly stirred and rubbed with the net chain as much as possible; the graph
