Random disposal not only causes environmental pollution but also wastes resources. Therefore, it is very necessary to recycle lithium batteries. Hydrometallurgy is a commonly used technical method, but the reaction medium has high viscosity and the metal mineral has high density, making it easy to deposit during the hydrometallurgical process. Currently used metallurgical equipment has the problem of being difficult to clean. There is a need to propose a hydrometallurgical equipment for lithium battery recycling that is easy to clean.

[0016] like Figure 5 , Figure 6 As shown, the feeding mechanism 7 includes a sleeve 71, a support leg 72, and a hopper 73. The sleeve 71 is located on the top of the upper housing 1, and the support leg 72 is installed on the lower part of the hopper 73. The support leg 72 is inserted into the sleeve 71 and fixedly connected by bolts. A sliding groove 74 is provided on the side wall of the hopper 73, and a screen frame 75 is slidably arranged in the sliding groove 74. A screen plate is provided on the bottom surface of the screen frame 75. Several cylinders 76 are installed inside the upper part of the hopper 73, and the output ends of the cylinders 76 are connected to the screen frame 75. A cover plate 77 is provided on the top of the hopper 73, and a feeding cylinder 78 is connected to the bottom of the hopper 73.

[0017] like Figure 4 As shown, the lifting mechanism 8 includes two sets of brackets 81, a reel 82, and a winding discharge machine 83 respectively arranged on both sides of the feeding mechanism 7. Any set of brackets 81 is erected above the feeding slot 6. The reel 82 is rotatably mounted on the bracket 81. The winding discharge machine 83 is installed on one side of the bracket 81.

[0018] The process of using this utility model: After the lithium battery casing is broken open, it is placed inside the screen frame 75 of the feeding mechanism 7. The screen frame 75 is vibrated by the cylinder 76, causing the powder in the lithium battery inside the screen frame 75 to be screened out from the battery casing. The powder leaks from the screen plate at the bottom of the screen frame 75 into the inner box 10. The lifting mechanism 8 drives the reel 82 through the winding discharge machine 83 to unwind the lifting rope 84, placing the lifting frame 9 between the locking blocks 15 on the support plate 14.

The lifting frame 9 has a liquid trough 19, and the inner box 10 is equipped with a filter screen 20. The reaction solution can enter the inner box 10 and react fully with the lithium battery powder. After the reaction is completed, the winding machine 83 drives the winding reel 82 to wind up the mixture and lift the lifting frame 9 out of the reaction tank 11, so that the lifting frame 9 and the inner box 10 are separated from the reaction solution. The inner box 10 is then removed from the lifting frame 9, and the unreacted lithium battery powder residue in the inner box 10 can be quickly cleaned. The upper housing 1 and the lower housing 2 are connected on one side by a hinge 3 and fixed on the other side by bolts. The upper housing 1 can be rotated by the hinge 3 to deflect the upper housing 1 to the other side of the lower housing 2. At this time, the lifting frame 9 is lowered by the lifting mechanism 8, and the inner box 10 can be quickly taken out from the lifting frame 9. The feeding mechanism 7 is mounted on the upper housing 1 via support legs 72 and sleeve blocks 71. Support legs 72 and sleeve blocks 71 are fixed by bolts. The feeding mechanism 7 can be quickly disassembled for easy cleaning.

Therefore, equivalent changes made according to the claims are still within the scope of this utility model.
