[0002] Lithium-ion battery is a common rechargeable battery widely used in mobile phones, laptops, electric vehicles and other devices. It stores and releases energy by the movement of lithium ions between the positive and negative electrodes. It is favored for its high energy density, long life and light weight. With the widespread application of batteries, the recycling of electrolyte has become an important environmental issue. The electrolyte contains toxic and harmful substances. If it is discarded at will or enters the environment directly without treatment, it will pollute the soil and water sources and affect the ecological balance. Therefore, the recycling and treatment of electrolytes has become crucial.

[0003] When recycling lithium-ion battery electrolyte, the battery needs to be cracked so that the internal electrolyte can flow out smoothly. However, ordinary battery electrolyte recovery and cracking devices are not convenient to limit the battery during cracking, resulting in the electrolyte easily splashing out when the battery is broken, causing extremely strong pollution to the surrounding environment and seriously endangering the health of the staff. In addition, some cracking devices are not convenient to crack multiple batteries at the same time, which reduces the battery cracking efficiency. In addition, ordinary cracking devices are not convenient to clean the damaged batteries after the electrolyte flows out.

Figure 4 and attached Figure 5 As shown, the battery residues on the surface of the filter plate 9 are not easily blocked, and the damaged batteries can also be automatically pushed into the second box body 2.

[0031] Working principle: When in use, first place the first box 1 in a suitable position, then connect the mains to power the entire device, then rotate and open the sealing door 6, place the batteries to be cracked on the filter plate 9 in turn, and the two partitions 16 separate each battery. Then use the external controller to start the cylinder 11. The cylinder 11 is a double-acting cylinder with high efficiency and good stability. The piston end of the cylinder 11 pushes the movable plate 12 down, and the movable plate 12 drives the cutting blade 13 to descend. As the movable plate 12 descends, the top of the limit plate 14 loses its obstruction. Under the influence of gravity, the limit plate 14, the blocking plate 15 and the partition 16 descend at the same time. After the bottom end of the blocking plate 15 is in contact with the top of the filter plate 9, the piston end of the cylinder 11 pushes the movable plate 12 to continue to descend, causing the limit plate 14 to slide along the two ends of the movable plate 12, cutting. The blade 13 slides through the blocking plate 15, and the partition 16 slides through the filter plate 9. When the bottom end of the movable plate 12 is in contact with the top end of the blocking plate 15, the bottom end of the cutting blade 13 cuts the battery, and the electrolyte flows down into the liquid collection box 7 along the circular holes and square grooves on the surface of the filter plate 9. The liquid collection box 7 can be slid out later to process the electrolyte in the liquid collection box 7, and then the external controller is used again to drive the piston end of the cylinder 11 to drive the movable plate 12 and the cutting blade 13 to rise. After the top end of the movable plate 12 contacts the top end of the limit plate 14, the movable plate 12 can drive the limit plate 14 to rise synchronously, and the limit plate 14 drives the blocking plate 15, and the blocking plate 15 drives the partition 16 to rise. After the distance between the partition 16 and the filter plate 9 is greater than the height of the push plate 18, the cylinder 11 can be closed.

[0032] Then, the second motor 8 is started by an external controller. The second motor 8 is a stepper motor with strong controllability and quick response. The output end of the second motor 8 drives the screw 17 to rotate. The screw 17 makes the push plate 18 slide along its outer surface. The push plate 18 drives the wire brush 19 to slide along the upper surface of the filter plate 9. The wire brush 19 cleans the battery residue on the upper surface of the filter plate 9, and the push plate 18 can push the broken battery through the channel 10 and fall into the second box 2. Then, the first motor 3 is started by an external controller. The first motor 3 is a DC brushless motor with stable operation and low noise. The output end of the first motor 3 drives the bearing seat to rotate. The bearing seat drives one group of crushing rollers 4 to rotate, and the other group of crushing rollers 4 meshes and rotates to further crush the battery. The crushed battery falls into the solid collection box 5, and the solid collection box 5 can be pulled out for processing later. The above is the entire working principle of the utility model.
