Waste lithium battery current collector recovery and separation device

Abstract

The invention discloses a waste lithium battery current collector recovery and separation device, which comprises a cutting box, a crushing box, an equipment box, a collecting box and a heating box. The upper end of the equipment box is provided with the cutting box and the crushing box. The equipment box is provided therein with the heating box. The crushing box and the heating box are in communication with each other through a blanking tube. The lower end of the crushing box is provided with a bracket. The bracket is provided with a baffle. The baffle is connected with the lower end of the heating box. The outer side of the equipment box is provided an electric push rod which is connected to the baffle. A sieve plate is disposed under the bracket. The collecting box includes a first collecting box and a second collecting box which are both connected to the inner wall of the equipment box. A discharge port is arranged on the side wall of the equipment box. One side of the sieve plateis provided with a discharge port. The first collecting box is disposed below the discharge port. The second collecting box is in communication with the bottom of the equipment box.

Description

technical field [0001] The invention relates to the technical field of lithium battery recovery, in particular to a recovery and separation device for waste lithium battery current collectors. Background technique [0002] With the increase in the use of electronic products, my country has become a major producer and consumer of lithium batteries in the world. A large number of used batteries are discarded, and a considerable part of them is directly mixed into the garbage. This is not only a waste of resources, but also pollutes the environment. [0003] At present, recycling companies basically rely on manual dismantling, especially the peeling of the current collectors of the positive and negative electrodes of the battery. Lithium cobalt oxide and carbon negative electrode powder, the stripping effect is not ideal. Contents of the invention [0004] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a recycling and ...

AI Technical Summary

Problems solved by technology

[0004] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides a recycling and separating device for waste lithium battery current collectors. By cutting the battery, the cells are crushed, and then the crushed particle cells are heated at high temperature, and thermal expansion and contraction are used to The difference makes the lithium cobaltate and carbon powder fall off automatically from the current collector, and sieves through the screen, which solves the problem of low efficiency of manual separation and recovery, improves work efficiency, saves manpower, and reduces costs
