Recycling separation system of lithium battery component materials

Abstract

The invention relates to a recycling separation system of lithium battery component materials. A feed conveying device of the system is matched with the feeding hole of a crushing device, a spray device is arranged in the crushing device, a middle conveying device is matched with the discharge hole of the crushing device and the inlet of a centrifugal separation device, the drainage port of the centrifugal separation device is connected with a precipitation device, a solid collecting device is matched with the centrifugal separation device, a waste gas collecting device is communicated with the crushing device, a control device is electrically connected with other devices except the precipitation device, and preferably, the spray device is arranged in the discharge hole of the crushing device; the middle conveying device comprises a chute, a water pump and an overflow storage tank; and the system also comprises a sound insulation device. The recycling separation system of the lithium battery component materials has skilful and reasonable design, is safe, efficient and environmentally-friendly, can eliminate the hidden dangers of combustion and explosion and the secondary pollution problem caused by the residual electric quantity, is convenient for recycling the crushed materials, and is suitable for large-scale popularization and application.

Description

technical field [0001] The present invention relates to the technical field of separation and recovery of constituent materials, in particular to the technical field of resource separation systems for constituent materials, and specifically to a resource separation system for constituent materials of lithium batteries. Background technique [0002] Lithium battery is a kind of electronic consumables. If the discarded lithium battery is not disposed of properly, the heavy metals such as cobalt contained in it will cause harm to the environment. On the other hand, metals such as Co, Cu, Li, Ni, Al, Fe, Zn, Ca, Mg and Mn contained in lithium batteries are all valuable mineral resources, and the content of cobalt, copper and lithium can be as high as 20 %, 7% and 3%. Take cobalt, the metal with the highest content, as an example, which is an internationally recognized strategic substance. my country's cobalt resources are extremely scarce and have always relied on foreign impo...
