A combined charged crushing device for scrapped lithium-ion power lithium batteries

Abstract

The invention discloses a charged crushing assembly device of a scrapped lithium-ion power lithium battery, and belongs to the field of waste battery crushing. The charged crushing assembly device solves the problems that an existing battery crushing technology easily generates combustion and easily generates explosion. A battery double-shaft shredding machine is arranged above a waste battery; a feeding hopper is arranged above the battery double-shaft shredding machine; a spray head is arranged inside shredding equipment to prevent combustion explosion; the upper end of an open type loader is arranged on the side wall of the feeding hopper; the lower end of a sealed type loader extends into a waste water tank; the upper end of the sealed type loader is connected with a feeding hole of a hammer type crusher; the upper end of the feeding hopper, the sealed type loader and a gas outlet of the hammer type crusher are connected with an inlet end of a suction ventilator through an air suction pipeline; and an outlet end of the suction ventilator is connected with a waste gas treater. The charged crushing assembly device adopts a direct charged crushing mode and does not need to discharge a battery, so that the period of crushing the battery is shortened, universal performances are strengthened, personnel operation is convenient, performances are reliable and the charged crushing assembly device is safer.

Description

technical field [0001] The invention relates to a waste battery crushing device, in particular to a waste lithium-ion power lithium battery charged crushing combination device, which belongs to the technical field of waste battery crushing. Background technique [0002] At present, the method before crushing and the crushing method of waste power battery recycling include the following steps: 1. Discharge the waste battery first; 2. Carry out pyrolysis treatment before the waste battery is crushed; Core, casing and electrodes, only the battery core is broken when broken. 4. The crushing method is divided into dry crushing and wet crushing. The above methods have the following disadvantages: 1. Improper discharge of waste batteries is prone to explosion; 2. Improper pyrolysis treatment before crushing is prone to electrolyte leakage; 3. The accuracy of cutting and separating waste batteries is difficult to control. Fourth, putting hard impurities into dry crushing is easy t...

AI Technical Summary

Problems solved by technology

The above methods have the following disadvantages: 1. Improper discharge of waste batteries is prone to explosion; 2. Improper pyrolysis treatment before crushing is prone to electrolyte leakage; 3. It is difficult to control the accuracy of waste batteries when they are cut and separated.

4. Putting hard impurities into dry crushing is easy to damage the equipment, and may threaten the safety of operators in serious cases

Wet crushing cannot be directly separated by wind or magnetic separation
