Method for recycling waste lithium batteries

Abstract

The invention belongs to the field of garbage recovery, particularly relates to a method for recycling waste lithium batteries, particularly relates to a device for recycling waste lithium batteries in the recycling process of the waste lithium batteries by using the method for recycling the waste lithium batteries. The device for recycling the waste lithium batteries comprises a shell, wherein the shell is in a step shape, a working cavity with an opening is formed in the shell, the opening of the working cavity is formed in the protruding part of the shell, V-shaped feeding holes are formed in the periphery of the opening of the working cavity, a rare metal sorting mechanism is arranged at the position, close to the V-shaped feeding holes, in the shell, a rare metal collecting box used for collecting rare metal powder and a shell collecting box used for collecting the outer skins of lithium batteries are arranged on the side, away from the V-shaped feeding holes, in the working cavity in a sliding mode, a pre-sorting mechanism used for removing steel skin is arranged between the rare metal sorting mechanism and the rare metal collecting box, and a shell sorting mechanism for sorting the aluminum sheet and the soft sheath is arranged in the working cavity close to the shell collecting box.

Description

technical field [0001] The invention belongs to the field of garbage recycling, in particular to a method for recycling waste lithium batteries. Background technique [0002] With the enhancement of people's awareness of environmental protection, the application of batteries has also developed from the original zinc-manganese dry batteries to more environmentally friendly lithium batteries. Although lithium batteries are more environmentally friendly than dry batteries, they also require a lot of rare metals in manufacturing. If lithium batteries Improper handling will also cause heavy metal pollution. The current lithium battery recycling process is mainly to crush the lithium battery, and then screen the heavy metal powder and the shell. The current crushing and screening are carried out step by step, which is usually not the case during the lithium battery crushing process. In a closed environment, heavy metal powder will float into the air, which cannot efficiently use h...

The current lithium battery recycling process is mainly to crush the lithium battery, and then screen the heavy metal powder and the shell. The current crushing and screening are carried out step by step, which is usually not the case during the lithium battery crushing process. In a closed environment, heavy metal powder will float into the air, which cannot efficiently use heavy metals, and will also cause respiratory diseases of the staff, and the outer packaging of lithium batteries is divided into aluminum shells, steel shells and soft shells. The current The sorting machine cannot sort the packaging shells
