Description

Technical Field

[0001] This utility model is an explosion-proof device for lithium battery recycling, belonging to the field of lithium battery application technology. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become the mainstream.

[0003] Publication number CN212830647U mentions a lithium battery recycling explosion-proof device. The explosion-proof box used to store the lithium batteries is a metal box with an inner wall containing an isolation layer and an inner explosion-proof layer to isolate external open flames and corrosive substances. A sealing cover is snapped onto the top of the explosion-proof box to prevent excessive contact between the waste lithium batteries and the human body, achieving a strong explosion-proof effect. However, it cannot effectively secure the internal batteries during use. In the event of a sudden stop or collision of the internal batteries, the batteries may catch fire or even explode. There is an urgent need for a lithium battery recycling explosion-proof device to solve the aforementioned problems. Utility Model Content

[0020] As the first embodiment of this utility model: a sealing groove 21 is provided on the upper surface of the explosion-proof box cover 11, and a sealing rod 111 is installed on the lower surface of the explosion-proof box cover 11. The size of the sealing rod 111 is the same as the size of the inside of the sealing groove 21. The longitudinal partition 3 is located inside two longitudinal limiting blocks 5 corresponding to each other front and rear. The transverse partition 4 is located inside two transverse limiting blocks 6 corresponding to each other left and right. Several slots are provided on the lower surface of the longitudinal partition 3 and the upper surface of the transverse partition 4. The longitudinal partition 3 and the transverse partition 4 are connected by two slots. Limiting grooves 72 are respectively installed at both ends of the outer surface of the sealing plate 7.

At this time, the explosion-proof box cover 11 is put on, and the sealing rod 111 is inserted into the sealing groove 21. After the cover is put on, the buffer disc 19 will stick to the surface of the lithium battery, and the top pressure spring 17 increases the friction between the buffer disc 19 and the surface of the lithium battery, thereby limiting the shaking of the lithium battery. Then, pinch the two limiting plates 71, compress the limiting spring 73, and then clamp the sealing plate 7 onto the surface of the explosion-proof box 2. Then release the two limiting plates 71, and the two limiting plates 71 will be pushed into the limiting groove by the limiting spring 73.
