Waste lithium ion power battery protection crushing process equipment

Abstract

The invention discloses a waste lithium ion power battery protection crushing process equipment. The equipment comprises a conveying belt assembly and a nitrogen tank, and the top end of the conveying belt assembly is arranged at a feeding opening of a crushing machine shell in an attached mode; and a nitrogen pipe connected between the nitrogen tank and the crushing machine shell achieve internal communication of the nitrogen tank and the crushing machine shell, the top of the crushing machine shell is connected with one end of a first conveying pipe in a penetrating mode, the other end of the first conveying pipe is installed on a cyclone dust collector, the lower end of the cyclone dust collector is connected with a storage bin used for collecting particle plates, and an air locking valve is mounted at a port of the storage bin. According to the waste lithium ion power battery protection crushing process equipment, an electrolyte volatile gas treatment structure is arranged inside the equipment, gas atmosphere protection can be conducted on a crushing device, detonation accidents are prevented, safety is better, the equipment can treat particulate matter generated by crushing, the particulate matter content in tail gas is effectively reduced, and the device is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery recycling, in particular to a process equipment for protecting and crushing waste lithium ion power batteries. Background technique [0002] Lithium-ion power battery is an energy storage product with high energy density. It is widely used in the field of new energy vehicles. The scrapped lithium-ion power battery needs to be crushed through a recycling device. However, the existing ion power battery protection crushing equipment is still There are some problems: [0003] For example, a lithium-ion battery crushing and recycling device with a publication number of CN209472076U includes a lithium-ion battery crushing and recycling body, and a waste lithium-ion battery crushing chamber is installed in the middle above the lithium-ion battery crushing and recycling body. The inside of the battery pulverizing chamber is equipped with a pulverizing spiral knife.... It is not equipped with...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a kind of waste lithium-ion power battery protection crushing process equipment, in order to solve the above-mentioned background technology, propose the existing ion power battery protection crushing equipment, it is not provided with the electrolyte volatilization gas treatment structure, during the crushing process of the device, the internal The concentration of volatile gas in the electrolyte is high, there is a certain risk of deflagration, and the safety is poor, and the device does not have the ability to screen broken particles, resulting in the mixing of particles of different sizes, which is not conducive to the problem of post-processing
