Battery crushing and sorting treatment process and treatment equipment thereof

Abstract

The invention belongs to the technical field of battery recovery treatment, and particularly relates to a battery crushing and sorting treatment process and treatment equipment thereof. The process comprises the steps of primary vibration transportation, coarse crushing of battery waste, secondary vibration transportation, primary separation of the battery waste, fine crushing of the battery waste, secondary separation of the battery waste, grinding and crushing of the battery waste, third separation of the battery waste and fourth separation of the battery waste. According to the process, Nickel-Cobalt-Manganese powder is effectively recovered in each stage of the battery waste crushing process, the recovery rate of the Nickel-Cobalt-Manganese powder is greatly increased, the adhesion rate of the Nickel-Cobalt-Manganese powder in each component is reduced, meanwhile, by virtue of the physical density difference of each component, iron-aluminum shells are separated and recycled after coarse crushing, copper particles are separated and recycled after fine crushing, the copper particles and aluminum particles are separated and recycled after grinding and crushing, the Nickel-Cobalt-Manganese powder is subjected to negative pressure recycling in each link, the separation effect is high, and all components with high purity can be recycled.

Description

Technical field:[0001]The invention belongs to the technical field of battery recycling and processing, and particularly refers to a processing technology and processing equipment for battery crushing and sorting.Background technique:[0002]There are many types of batteries. Commonly used batteries include dry cells, accumulators, and small-sized micro batteries. With the strong development trend of new energy vehicles in recent years, the scrap standard of the power battery as the power core of new energy vehicles is that the battery capacity is less than 80%, which means that new energy vehicles will have to be replaced every 3 to 5 years. Power Battery. Among them, in 2020, the scrap volume of power batteries for pure electric passenger cars and hybrid passenger cars will reach 170,000 tons. Therefore, the recycling of waste power batteries has become the focus of attention in the industry.[0003]The existing Chinese invention patent application document (application publication nu...

AI Technical Summary

Problems solved by technology

It can be seen that this method is to continue to break the waste battery and the pole piece package to a broken state, and then uniformly sort each component in sequence, which makes it difficult to guarantee the purity of the sorted components. , The volatility is large, and it is impossible to effectively separate copper, aluminum, positive and negative electrode powder (that is, black powder, also known as nickel-cobalt-manganese powder, which contains nickel, cobalt, manganese and other metals)
