Efficient lithium iron phosphate lithium battery automatic disassembling and recycling system and recycling method

Abstract

The invention discloses an efficient lithium iron phosphate lithium battery automatic disassembling and recycling system and a recycling method. A uniform feeding system is connected with the feeding end of a first belt conveying line, the first belt conveying line is connected with the feeding end of a crushing system, the discharging end of the crushing system is connected with a black powder collecting system, the black powder collecting system is connected with the low-temperature volatilization furnace and the high-temperature rotary kiln, the low-temperature volatilization furnace is connected with the copper and aluminum particle collecting system, and the black powder collecting system and the copper and aluminum particle collecting system are both connected with the diaphragm collecting system and the tail gas treatment system. The efficient lithium iron phosphate lithium battery automatic disassembling and recycling system is low in dust leakage possibility and free of electrolyte leakage, the production line environment is ensured, and the safety coefficient of the production line is improved; and a dust gas treated by the tail gas treatment system can reach the emission standard of the local hazardous waste incineration pollution control standard, and tail gas treatment equipment does not need to be additionally arranged.

Description

technical field [0001] The invention relates to the technical field of lithium ion battery manufacturing, in particular to an efficient automatic dismantling and recycling system and recycling method for lithium iron phosphate lithium batteries. Background technique [0002] Lithium-ion batteries have the advantages of high energy, long life, and low pollution, and are widely used in many fields such as mobile phones, computers, electric bicycles, electric vehicles, and national defense. Especially in recent years, with the explosive growth of electric vehicles, the large-scale power lithium battery market will be accompanied by a substantial increase in the demand and scrapping of lithium batteries. Waste lithium-ion batteries contain a lot of available resources, such as iron, copper, aluminum and other valuable metals. If these waste lithium batteries are not recycled properly, it will cause a great waste of resources and environmental pollution. At the same time, the po...
