Background Along with the rapid development of new energy automobiles and energy storage industries, the recycling of waste lithium batteries has become a key link for guaranteeing resource circulation and environmental protection. The dry recovery process has the advantages of low energy consumption, no secondary pollution, high resource recovery rate and the like, and is widely applied to the recovery treatment of waste lithium batteries. In the dry recovery process, the crushed and screened battery pole piece material is separated from a current collector (copper foil and aluminum foil) by stripping equipment, and then the separated active material and the current collector are respectively subjected to subsequent recovery treatment. In the dry recovery process, the product treated by the stripping device mainly comprises two parts, namely active material powder stripped from the current collector and current collector fragments still attached with part of residual active material. Currently, the stripped current collector fragments are generally transported directly to a subsequent current collector recovery process by a transport device. The fine active substance powder attached to the surface of the collector chips with the residual powder is easily separated and drifted into the air during the transportation and transfer processes, particularly during the falling, collision and vibration of equipment, so that dust emission is generated. The method not only can pollute the working environment and influence the safety production and the health of staff, but also can cause the loss of valuable materials (active substances) and reduce the overall recovery rate.
