Description

Technical Field

[0001] This invention relates to the field of retired lithium battery recycling technology, and in particular to a refined dismantling and recycling production line for retired lithium batteries. Background Technology

[0002] A refined dismantling and recycling production line for retired lithium batteries is a supporting facility for the recycling of retired lithium batteries. The evaporation of lithium battery electrolyte is harmful to human health and the environment. Lithium battery electrolyte contains various chemical components, including organic solvents and lithium salts. These components may cause various health hazards and pollute the environment during the evaporation process. Therefore, the recycling of retired lithium batteries requires automated processing by specialized dismantling and recycling production lines. With the continuous development of technology, the requirements for the manufacturing process of refined dismantling and recycling production lines for retired lithium batteries are becoming increasingly stringent.

[0003] Existing retired lithium battery recycling lines have certain drawbacks. Traditional recycling processes, which involve on-charge crushing or manual dismantling, are prone to short circuits, fires, and even explosions. Traditional recycling processes also have low dismantling efficiency, relying on manual sorting and feeding, resulting in low automation. Traditional physical dismantling struggles to completely separate complex components, leading to low recovery rates of valuable metals. Traditional hydrometallurgical processes are lengthy, energy-intensive, and prone to secondary pollution. The high energy consumption and low efficiency of traditional processes result in high costs, negatively impacting practical applications. Therefore, we propose a refined dismantling and recycling line for retired lithium batteries. Summary of the Invention
