Lithium battery recovery device

Abstract

The embodiment of the invention discloses a lithium battery recovery device, relates to the technical field of lithium battery recovery, and mainly aims to solve the problem of non-uniform volume of crushed metal powder in the existing lithium battery recovery device. The lithium battery recovery device comprises a pre-crushing mechanism, a main body mechanism, an air blowing assembly and a second crushing mechanism. The air blowing assembly can blow up metal fragments or particles which are preliminarily crushed by the pre-crushing mechanism in the second crushing bin, and a telescopic assembly in the second crushing mechanism can drive the second crushing assembly to move while further crushing the metal fragments or particles floating in the second crushing bin into metal particles with small diameters. The metal fragments or particles with larger diameters continue to move around in the second crushing bin and are crushed by the second crushing assembly, and the metal particles with smaller diameters penetrate through a filtering part on the second crushing bin and are discharged, so that the metal shells in the lithium batteries can be quickly and uniformly crushed, and the collected metal particles are relatively uniform in size.

Description

technical field [0001] The present application relates to the technical field of lithium battery recycling, in particular to a lithium battery recycling device. Background technique [0002] Lithium-ion batteries have rapidly occupied the power source market for portable electronic products and equipment due to their significant advantages such as high voltage, large specific volume, long life, and no memory effect. However, it is undeniable that lithium-ion batteries Batteries are electronic consumables, and their average service life is about 2-4 years. Therefore, if the lithium batteries are not recycled properly, they will inevitably pose an embedded pollution threat to the environment; as we all know, lithium batteries are mainly composed of shells, positive and negative electrodes , electrolyte and separator. At present, the recycling of waste lithium batteries is mainly for the recovery of precious metals and cobalt lithium, and the recovery of precious metals mainly ...

Problems solved by technology

[0002] Lithium-ion batteries have rapidly occupied portable electronics since their commercialization due to their significant advantages such as high voltage, large specific volume, long life and no memory effect. The power source market for products and equipment, but it is undeniable that lithium-ion batteries are electronic consumables, and their average service life is about 2-4 years. It is well known that lithium batteries are mainly composed of shells, positive and negative electrodes, electrolytes and diaphragms. At present, the recycling of waste lithium batteries is mainly for the recovery of precious metals and cobalt lithium, and the recovery of precious metals mainly depends on Traditional crusher crushes before recycling

[0003] When the existing lithium battery recovery device crushes and recycles lithium batteries, it cannot guarantee that the size of the technical powder discharged from the discharge port meets the requirements. Uneven metal powder is not conducive to later recycling
