[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Example 1, with reference to Figures 1 to 5 , a special explosion-proof crushing device for waste lithium batteries, including a box body 1, which is connected to the box body 1 by a connecting shaft and is equipped with two sets of cover bodies 2. The cover body 2 is used to place lithium batteries. When the two sets of cover bodies 2 are close to each other and fit into the box body 1, the impact force generated by the explosion of the lithium battery can be intercepted. The outer wall of the box body 1 is slidably connected to a frame body 4, and the frame body 4 is connected to two sets of rollers 5 by a connecting shaft. The two sets of rollers 5 are respectively fitted with the two sets of cover bodies 2. Push rods 3 are installed at one end and the other end of the box body 1. The output ends of the two sets of push rods 3 are connected to the frame body 4. The push rods 3 drive the frame body 4 to move upward, so that the two sets of rollers 5 can drive the two sets of cover bodies 2 to fit each other and fit into the box body 1. At this time, the two sets of cover bodies 2 can intercept the impact force generated by the explosion of the lithium battery.

[0024] In this embodiment, a water tank 6 is fixedly connected to the box body 1, and a pump body 7 is installed in the water tank 6. The model of the pump body 7 is selected according to actual work requirements. The pump body 7 is connected to a pipe body 8, and the pipe body 8 is connected to multiple groups of hoses 9. The multiple groups of hoses 9 are all equipped with nozzles 10. The pump body 7 can spray the water in the water tank 6 into the box body 1 at the multiple groups of nozzles 10, so as to extinguish the fire of the lithium battery. The multiple groups of nozzles 10 are connected to a group of cover bodies 2. Two groups of motors 12 are installed at the box body 1. The model of the motor 12 is selected according to actual work requirements. The output ends of the two groups of motors 12 are connected to crushing rollers 13. The electronic control 12 can drive the two groups of crushing rollers 13 to crush the lithium battery. The two groups of crushing rollers 13 can be used to crush the lithium battery. The rollers 13 are all connected to the box body 1 for rotation through bearings. A slide 15 is slidably connected to the box body 1. The slide 15 is used to guide the falling lithium battery debris to the discharge port 17 for discharge. A handrail 16 is fixed to the slide 15. A discharge port 17 is provided at the box body 1 for discharging the crushed lithium batteries. A temperature sensor 11 is installed at one group of covers 2. The temperature sensor 11 is used to detect the high temperature generated by the explosion of the lithium battery, which can then trigger the pump body 7 to spray the water in the water tank 6 into the box body 1 through the nozzle 10 to extinguish the burning lithium battery. A torsion spring 14 is fixed between the two groups of covers 2 and the box body 1. The torsion spring 14 gives the two groups of covers 2 a force to expand outward.

[0025] The working principle of this embodiment is as follows: when in use, water is injected into the water tank 6, and the lithium batteries are placed in the two groups of cover bodies 2. After placement, the two groups of motors 12 are connected to an external power supply, and the two groups of crushing rollers 13 can rotate. At this time, the two groups of push rods 3 are connected to an external power supply, and the two groups of push rods 3 can drive the frame 4 to move the two groups of rollers 5 upward. The rollers 5 can rotate the two groups of cover bodies 2 upward and close to each other, and fit with the box body 1. The lithium batteries in the cover body 2 can contact the two groups of crushing rollers 13 for crushing. The crushed lithium batteries will fall to the slide plate 15 and be discharged through the discharge port 17. If the lithium battery catches fire and explodes during crushing, the impact force generated by the explosion will be intercepted by the two groups of cover bodies 2. At the same time, the temperature sensor 11 will detect high temperature and run the pump body 7. The pump body 7 will spray the water in the water tank 6 through multiple groups of nozzles 10 into the box body 1, thereby extinguishing the fire generated by the lithium battery.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
