A kind of recovery processing method of waste lithium battery

Abstract

The invention discloses a recycling and processing method of waste lithium batteries. The recycling and processing method of waste lithium batteries comprises the following steps: transporting the waste lithium batteries to the sieve cylinder on the screening device through a feeding conveyor belt, and disposing of waste lithium batteries of different sizes Flow out along the sieve holes of different pore sizes on the screen, and flow into the cleaning tank on the cleaning device through the blanking frame; add cleaning solvent into the cleaning tank and soak to remove the stains on the outer surface of the used lithium battery; the surface is stuck with The waste batteries cleaned with solvent are transported forward through the conveyor belt, and at the same time, the third drive motor is started to rotate back and forth in a fan shape, so that the shell rotates back and forth along the fan shape of the pillar, and multiple groups of fan blades rotate at the same time, blowing the heat on the electric heating plate to the On the transported lithium batteries, the lithium batteries are dried during the transportation and collection process; the present invention can classify and screen waste batteries according to their size, and carry out centralized recovery and treatment of waste lithium batteries of the same model size.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and relates to a method for recycling and processing lithium batteries, in particular to a method for recycling and processing waste lithium batteries. Background technique [0002] Abandoned lithium batteries contain a large amount of non-renewable and high economic value heavy metal resources. The positive electrode sheet material in the lithium battery is lithium cobalt oxide powder, and the negative electrode sheet material is graphite powder. Both the positive electrode sheet and the negative electrode sheet contain a large amount of cobalt, Nickel, manganese, copper, aluminum and other metal materials; if waste or unqualified lithium batteries can be effectively recycled, it can not only reduce the pressure of waste batteries on the environment, but also avoid the waste of cobalt, nickel, manganese and other heavy metal resources. Therefore, due to the shortage of resources and th...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that all different types of lithium batteries are usually collected and processed in a centralized manner, but the composition of different types of lithium batteries is different, which leads to the recovery process of lithium batteries. In this process, the purpose of recycling cannot be carried out; the stains on the surface of waste lithium batteries affect the recycling of lithium batteries in the later stage, and the existing cleaning of waste lithium batteries has poor cleaning effect, which affects the process time of waste battery recycling. problem, and propose a recycling method for waste lithium batteries
