With the continuous progress of science and technology, the development of the electronic technology industry is growing, electronic products are being updated more and more quickly, the number of used lithium batteries is gradually increasing, the waste lithium batteries will cause greater pollution to the environment, in order to reduce the pollution of the environment, began to try to use the physical mechanical crushing of waste lithium batteries, however, the existing processing system for lithium batteries crushing treatment is not thorough enough, the discharge of materials still exist in the environmental pollution. There are still substances that exist in the discharged materials that pollute the environment. In addition, when collecting the positive and negative electrode powder and metal, because the fan is at the front of the collection device, there is a bend in the pipe for conveying the powdered material, so that the powdered material is not strong enough to be conveyed, and it is easy to stay or accumulate in the inner wall of the pipe, so that the separation effect is not good.
Lithium battery recycling processing equipment a lithium battery treatment process, including the following steps: the waste lithium battery into the shredder for shredding, shredded batteries into the crusher for crushing, shredder and crusher dust generated by the induced fan Ⅰ into the activated carbon absorption tower for absorption, after the absorption of the activated carbon absorption tower airflow into the water spray tower for dust removal. During the crushing process, the diaphragm paper on the positive and negative electrode pieces is broken up, and the broken up material is attracted into the collector II by the high pressure fan II, and then the dust generated in the crushing is purified by the pulse dust collector II; the material entering the collector II enters the airflow sorter I, and the airflow sorter I collects the dust and the diaphragm paper in the positive and negative electrode pieces under the action of airflow and vibration. The dust in the airflow sorter I enters the magnetic separator, and the material in the crusher cell that has not been broken up also enters the magnetic separator.
The magnetic separator separates the iron in the material by magnetic force, and the material separated from the iron enters the crusher for crushing to 15-25 mesh, and the material crushed by the crusher is conveyed to the analyzer, which separates the crushed material by wind selection and sorts out the positive and negative electrode powder with small specific gravity and the metal material with large specific gravity. The dust of collector III is purified by pulse purifier III, and the metal materials sorted out by the analyzer enter the airflow sorter II for sorting, and the airflow sorter II sorts out the copper and aluminum powders with higher specific gravity and the positive and negative powders with lower specific gravity by wind sorting. The material in the airflow sorter II enters the airflow sorter III for further sorting, and the airflow sorter III separates the metal with higher specific gravity and the positive and negative powder with lower specific gravity again through wind sorting. The positive and negative powder in the diverter valve is attracted by the high pressure fan Ⅰ into the collector Ⅰ for collection, and the dust enters the pulse dust collector Ⅰ for purification.
The process of Xingmao Environmental Protection Lithium Battery Recycling Equipment Utility Model separates and recycles the diaphragm paper, positive and negative electrode powder and metal through multiple sorting, and the obtained diaphragm paper, positive and negative electrode powder and metal are very pure and can be directly recycled and reused. Through the combination of shredding, crushing, crushing and airflow sorting process to achieve resource recycling of metal and positive and negative electrode powder in waste lithium batteries.
