Scraped power lithium battery nitrogen-protection crushing equipment

Abstract

The invention discloses scraped power lithium battery nitrogen-protection crushing equipment, and belongs to the technical field of waste battery disposal. The scraped power lithium battery nitrogen-protection crushing equipment solves the problem that safety of operators is threatened due to the fact that combustion is easily generated and explosion easily happens in the existing battery crushing technology. An outlet of a shredding machine of the scraped power lithium battery nitrogen-protection crushing equipment corresponds to an inlet of a water tank; a feeding hopper is arranged above the shredding machine; a gas outlet is formed in the top cover of the feeding hopper; the upper end of an insulating conveyor is arranged on the side wall of the feeding hopper; the lower end of a crushing conveyor extends into the water tank; the outlet of a discharge hopper of the shredding machine is opposite to the crushing conveyor; a nitrogen making machine communicates with the inner part of a discharge hopper of the shredding machine through a gas conveying pipeline; and a nitrogen gas refrigerator and a solenoid valve are arranged on the gas conveying pipeline. The scraped power lithium battery nitrogen-protection crushing equipment adopts a direct powered crushing mode without discharging batteries, so that period of crushing batteries is shortened, universal performance is strengthened, staff operation is convenient, performances are reliable, and the scraped power lithium battery nitrogen-protection crushing equipment is safer.

Description

technical field [0001] The invention relates to crushing equipment for scrap power lithium batteries, in particular to nitrogen protection crushing equipment for scrap power lithium batteries, and belongs to the technical field of waste battery treatment. 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 cru...

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
