Lithium battery graphite negative electrode material recycling device

Abstract

The invention discloses a lithium battery graphite negative electrode material recycling device. The device comprises a machine body in an inverted-circular-truncated-cone shape and supporting legs arranged on the machine body, the side wall of the machine body is coaxially and rotationally connected with a rotating ring through a rotating shaft, the rotating ring is of a hollow structure, a hollow layer of the rotating ring is tightly filled with a plurality of thermal expansion balls, a plurality of crushing rollers are rotationally connected to the inner wall of the machine body, the crushing rollers are in transmission connection with the rotating shaft through a synchronous belt, an arc-shaped plate is embedded in the position, above the rotating ring, of the side wall of the machinebody, and an arc-shaped cavity is formed in the side wall of the arc-shaped plate. According to the device, drying, crushing and cooling are integrated on one device, so that excessive space is not occupied during installation; in the using process, the rotating shaft intermittently and periodically rotates so that noise cannot be generated due to high-speed rotation, and meanwhile motor driving is not needed; and the crushing speed can be automatically adjusted according to the cooling speed, so that the power utilization is scientific, the energy consumption is low, and the modern environment-friendly and energy-saving standards are well met.

Description

technical field [0001] The invention relates to the technical field of lithium battery recovery, in particular to a lithium battery graphite negative electrode material recovery device. Background technique [0002] In the prior art, the recovery of the negative electrode of the discarded lithium battery is firstly pickled. The pickling is to peel off the copper foil wrapped on the graphite of the negative electrode of the lithium battery, and then dry the negative electrode material of the lithium battery after pickling, and the drying is completed. Finally, crushing and cooling are carried out. In the above process, drying, crushing and cooling need to be carried out by different equipment. The recycling of lithium battery graphite negative electrode materials requires large investment, poor effect, high operating costs, and long recycling and processing cycles, which seriously restrict lithium battery graphite negative electrodes. The rapid development of material recycli...
