[0033] In order to solve the problems existing in the prior art and overcome its defects, and realize the purpose of high-purity recycling of copper-aluminum materials in waste materials, the technical scheme adopted by the present application is:

[0034] As Figure 1 The present application is a copper-aluminum particle sorting device after waste lithium battery crushing, which is a subsequent device of the waste lithium battery crusher production process, and aims to solve the problem of sorting the copper-aluminum particles generated at the end of the production process by physical methods, and has certain requirements for the purity of the sorted copper and aluminum.

[0035] The sorting device first screens the copper-aluminum mixture, classifies it according to different particle sizes, and according to the principle that the specific gravity of copper and aluminum is different, the screened mixture is respectively fed into the corresponding specific gravity sorting machine. The device of the present application can efficiently physically sort the copper-aluminum mixture generated in the waste lithium battery crushing and sorting process, and obtain high-purity copper and aluminum particles.

[0036] The large particle outlet is arranged on the upper side of the vibrating screen 1; the small particle outlet is arranged on the lower side of the vibrating screen 1; and the screen height position of the vibrating screen 1 corresponds to the height of the large particle outlet.

[0037] After crushing, the large particle material is blocked by the upper screen and is first separated, enters the conveying pipeline 3 and is sent to the conveying pipeline 3, and then is sent to the large particle sorting machine 4 for copper-aluminum sorting; the smaller material leaks to the lower part and is sent to the small particle sorting machine 6 through the conveying pipeline 3 for copper-aluminum sorting.

[0038] The vibration of the vibrating screen 1 is driven by the vibrating screen motor 2.

[0039] The transmission mechanism of the vibrating screen 1 converts the rotary motion of the vibrating screen motor 2 into reciprocating vibration of the vibrating screen 1, and the material can be screened and moved.

[0040] The sorting device is provided with a fan 8; the fan 8 is connected with the large-particle sorting machine 4 and the small-particle sorting machine 6 through air feeding pipes respectively.

[0041] The fan 8 arranged in the sorting machine makes the internal materials keep tumbling, under the action of the inclined plate device and the vibration motor, due to the different specific gravities of copper and aluminum, the materials are blown by the fan and then fall in different positions during falling, the copper particles fall earlier, and the aluminum particles are blown far away, the copper and aluminum are separated from different positions of the sorting machine;

[0042] The air feeding pipes are communicated with the air inlets of the side surfaces of the large-particle sorting machine 4 and the small-particle sorting machine 6 respectively; the positions of the copper particle outlet and the aluminum particle outlet are arranged in sequence according to the air direction.
