At present, there are mainly 2 ways to recycle used power lithium-ion batteries: one is the secondary use; the other is disassembly and recycling. The raw material composition of lithium batteries mainly includes: positive electrode material, negative electrode material, diaphragm, electrolyte. In order to eliminate the safety risks in the recycling process of lithium-ion batteries, pre-discharge must be carried out. The main discharge method is the immersion method which is simple and feasible, is the current common method. Waste battery recycling first of all to achieve the active material and aluminum foil, plastic and diaphragm and metal material separation, screening out valuable metal electrode materials, in the industrial recycling is often used in the mechanical crushing method of physical separation of battery disassembly and separation of electrode active material, fluid collection and battery shell and other battery components by crushing, sieving, magnetic separation, fine crushing and classification, so as to obtain valuable high content of the material . How to combine the application of lithium battery recycling and processing equipment?
Lithium battery recycling processing equipment crushing and sorting recycling copper and aluminum process components: loading conveyor, shredder twin shaft, shredder, quantitative feeding bin, screw conveyor, grinder, airflow loader, pipeline, cyclone unloader, fan, shutdown fan, vibrating screen, discharge screw conveyor, airflow loader, cyclone unloader, shutdown fan, airflow specific gravity separator, screw conveyor, pulse dust collector, electric cabinet, etc. Process flow: The pre-treated battery is sent to the hammer crusher for coarse crushing through the conveyor, and the black powder is sorted out by the vibrating sifter. The remaining materials will be sorted out by the magnetic separator to sort out the iron in the materials. The conveyor sends the sorted material to the second crusher for crushing again, and then the black powder is sorted out by the vibrating sifter, and the remaining material goes to the vortex crusher for crushing, and the vibrating sifter sorts out the copper and aluminum powder. The processing line is equipped with a dust collection device, which collects the dust of the complete processing line under negative pressure, and then enters the pulse dust collector and spray tower for exhaust gas purification after vibrating and screening, and then discharges at high altitude to meet the standard.
The existing waste lithium battery treatment process has low recovery rate, easy to produce secondary pollution, and the material is difficult to be further recycled and other defects, so we propose whether the lithium battery can be crushed and recycled by crushing method, which can finely recover the copper and graphite and other metals. The environmental protection waste lithium battery recycling and treatment production line can realize the graded separation of waste materials in waste lithium batteries by improving the overall recycling process, and at the same time avoiding the pollution of the environment during its treatment.
