[0002] Lithium-ion batteries are high-performance rechargeable batteries, mainly composed of a positive electrode, a negative electrode, an electrolyte, and a separator. The positive electrode commonly uses lithium compounds, while the negative electrode is mostly graphite. During operation, lithium ions repeatedly insert and extract between the positive and negative electrodes to achieve the charging and discharging process. They have advantages such as high energy density, low self-discharge rate, and long cycle life, and are widely used in many fields such as mobile phones, laptops, and electric vehicles, playing an important role in promoting modern life and technological development.

[0038] The working principle and use process of the utility model:

[0039] First, the operator starts the fourth motor 22 and puts the waste lithium battery above the two crushing wheels 24. With the operation of the fourth motor 22, the drive shaft 23 and the crushing wheel 24 begin to rotate. At this time, the waste lithium battery is crushed and disassembled into battery waste and electrolyte by the rotating crushing wheel 24. The electrolyte moves to the lower side of the filter plate 3 through the filter plate 3, while the battery waste stays on the upper side of the filter plate 3. At this time, the operator starts the fifth motor 29. With the operation of the fifth motor 29, the double-threaded screw rod 30 rotates and moves the two moving blocks 31 towards each other. At this time, the first connecting rod 33 begins to rotate with the movement of the moving block 31, and the second connecting rod 34 also begins to rotate with the rotation of the first connecting rod 33. Finally, the other end of the second connecting rod 34 drives the connecting plate 27 to move backward as a whole. In this process, the extrusion plate 25 extrudes the battery waste on the upper side of the filter plate 3, so that the electrolyte remaining in the battery waste is squeezed out.

[0040] Then the operator starts the second motor 14 and then starts the third motor 20. The operation of the second motor 14 makes the rotating shaft 15 and the closing plate 16 begin to rotate, thereby removing the blocking of the closing plate 16 to the right surface of the treatment box 1. The operation of the third motor 20 makes the single-threaded screw rod 21 begin to rotate. At this time, the inclined plate 18 and the push plate 17 begin to move to the right under the drive of the single-threaded screw rod 21. Finally, the battery waste on the upper side of the filter plate 3 is pushed out to the right side of the treatment box 1 as a whole by the push plate 17.

[0041] When the operator needs to replace the filter plate 3, the operator starts the first motor 8. With the operation of the first motor 8, the circular shaft 9 and the driving rod 10 begin to rotate. In this process, the movable plate 6 and the plug 7 begin to move upward under the drive of the driving rod 10. Finally, when the plug 7 is separated from the inner surface of the pull plate 2, the fixation of the pull plate 2 as a whole is removed. At this time, the operator can directly pull out the pull plate 2 and the filter plate 3 for replacement.
