Waste power batteries that have been scrapped or gradually used have no use value, but these batteries still contain a large amount of electrolyte, as well as non-ferrous metals (aluminum foil, copper foil) and valuable materials (positive and negative materials). If they are not handled or handled badly, they will not only pollute the environment, but also waste resources. The new lithium battery recycling equipment directly recovers positive electrode materials and negative electrode materials from waste lithium batteries, accurately separates and recovers electrolyte, shell, positive electrode metal and negative electrode graphite, battery production line and improves the resource utilization rate of waste lithium batteries.

The utility model relates to a lithium battery recycling and processing device, including a feed conveyor, a double shaft crusher, a crusher, a linear screen, a mill, a tumbler screen, a second linear screen, a specific gravity separator, a magnetic separator set on top of the conveyor, a dust collection pipe connected to a pulse separator, and a pulse separator connected to the conveyor and the dust collection device, which realizes the effective separation of different materials, labeling machineand is conducive to the categorization of the resources for recycling.

A method of recovering valuable metal from a waste lithium battery, comprising the steps of.

1. preparing materials: the raw material is a waste material lithium battery after discharge data processing;

2. initial crushing: the initial crushing particle size is less than 40mm; and

3. de-powdering:

4. fine crushing;

5. sifting: the raw materials after the fine crushing problem processing are sifted, so that the positive and negative electrodes as well as the materials are separated from iron, copper and aluminum;

6.Recovery of valuable metals

With China's new energy vehicle cumulative production growth,Lithium battery recycling the current power battery cumulative supporting capacity of more than 131GWh, the industry scale of the world's first. The "harmless and resourceful treatment" of waste batteries has become a key link in the industry chain, and optimizing the comprehensive recovery rate of valuable metals has become a top priority. The recovery of valuable metals needs to solve the problems of lithium battery anode plate powder removal and subsequent separation of valuable metals. At present, the common treatment methods for anode plate depowdering are mechanical separation and heat treatment.
