Abstract

The invention relates to the technical field of waste battery treatment, and discloses a waste dry battery pole piece treatment and recovery system and method. The system comprises a primary crusher, a conveyor, a hammer type crushing device, a negative pressure extraction device, a collecting hopper and a screening device, wherein the primary crusher is used for primarily crushing materials, the feeding end of the conveyor is connected with the primary crusher, the discharging end of the conveyor is connected with the hammer type crushing device, the discharging end of the conveyor is higher than the feeding end, and the hammer type crusher is used for beating and crushing the materials crushed by the primary crusher so as to enable the materials to be in a powder particle shape; the negative pressure extraction device is arranged below the collecting hopper so as to extract the materials crushed by the hammer type crusher into the collecting hopper under the negative pressure; and the screening device is arranged below a discharging port of the collecting hopper so as to obtain copper particles, aluminum particles and black powder through screening. According to the system and method, the materials are crushed in a beating mode, so that the heating and fire of the materials caused by friction crushing in a cutting mode are prevented, and the potential safety hazard is reduced.

Description

technical field

[0001] The invention relates to the technical field of waste battery treatment, in particular to a waste dry battery pole piece treatment and recovery system and method. Background technique

[0002] In the process of promoting the development of new energy, the output of batteries has gradually increased, and the disposal of waste batteries has become an urgent problem to be solved. Batteries contain a lot of valuable metals. In order to reduce the pollution of waste batteries to the environment and recover valuable metals, it is necessary to process and recycle waste batteries.

[0003] However, at present, the existing dry battery pole piece processing system has many devices, complex devices, and relatively difficult operation. Due to the large number of equipment, the power consumption is relatively large, which increases the cost and causes economic pressure. Moreover, in the existing dry battery pole piece processing system, the black powder in the d...
