Recovery and shredding processing equipment for waste lithium battery and processing technology thereof

Abstract

The invention relates to the technical field of waste lithium battery recovery, and discloses recovery and shredding processing equipment for the waste lithium battery and the processing technology thereof. The recovery and shredding processing equipment for the waste lithium battery comprises a physical decomposition device, a second double-shaft shredding machine and a tunnel type hot air circulating drying oven, a crusher, a vibration screening machine, a cyclone separator positioned below the vibration screening machine, and a closed conveyor; the physical decomposition device communicateswith the second double-shaft shredding machine through a screw conveyer in a transmission mode, the second double-shaft shredding machine communicates with the tunnel type hot air circulating dryingoven in a transmission mode, and the tunnel type hot air circulating drying oven communicates with the crusher in a transmission mode; and the crusher communicates with the vibration screening machinein a transmission mode, the vibration screening machine communicates with the cyclone separator in a transmission mode, and the cyclone separator communicates with the closed conveyor in a transmission mode. According to the recovery and shredding processing equipment for the waste lithium battery, the safe crushing and decomposition of the lithium batteries can be achieved; and moreover, the waste lithium batteries can be produced and handled in a large scale, and the process of handling and recovering the waste lithium batteries can be extremely environment-friendly.

Description

technical field [0001] The invention relates to the technical field of waste lithium battery recycling, in particular, to a waste lithium battery recycling and shredding treatment equipment and a treatment process thereof. Background technique [0002] The recycling of waste batteries refers to the recycling of used batteries. The most widely used industrial batteries in China are lead-acid batteries, and lead accounts for more than 50% of the total cost of batteries. Pyrochemical, hydrometallurgical and solid-phase electrolytic reduction technologies are mainly adopted. . The shell is made of plastic, which can be recycled, and basically achieves no secondary pollution. Nickel-cadmium, nickel-hydrogen and lithium-ion batteries are mostly used in small secondary batteries. Cadmium in nickel-cadmium batteries is one of the heavy metal elements strictly controlled by environmental protection. Organic electrolytes in lithium-ion batteries, nickel-cadmium and nickel-hydrogen ba...
