[0027] Working principle:

[0028] By machining internal threads on the inner side of the explosion-proof cover 9 and rotating the explosion-proof cover 9, the explosion-proof cover 9 rotates along the threaded rod 7. When the explosion-proof cover 9 moves to the top of the outer tank 3, due to the external threads machined on the outer side of the outer tank 3, the explosion-proof cover 9 is threadedly connected to the outer tank 3, improving the stability of the explosion-proof cover 9. And a threaded rod 7 is provided at the middle position of the explosion-proof cover 9, and a sealing nut 8 is provided on the outer side of the threaded rod 7. After the explosion-proof cover 9 is fixed, rotate the sealing nut 8 to move it to the top of the explosion-proof cover 9. The meshing direction of the sealing nut 8 is opposite to the meshing direction of the explosion-proof cover 9, which can prevent the explosion-proof cover 9 from loosening and perform secondary fixation on the explosion-proof cover 9, further improving the stability of the explosion-proof cover 9 and enhancing the explosion-proof performance of the explosion-proof cover 9. By providing a double-layer tank of the outer tank 3 and the inner tank 12, its protection performance is improved. And a shock-absorbing rod 11 is provided between the outer tank 3 and the inner tank 12. When the explosive in the inner tank 12 explodes, the impact force generated by the explosion impacts the inner wall of the inner tank 12, causing the inner wall of the inner tank 12 to be deformed by the explosion stress. At this time, the inner tank 12 squeezes the ejector rod 19, and the ejector rod 19 drives the piston plate 18 to slide in the sleeve 15. The piston plate 18 causes the air pressure in the sleeve 15 to rise rapidly, and at the same time compresses the shock-absorbing spring 17. The compression of the inert gas forms a damping structure of the shock-absorbing spring 17, enabling the shock-absorbing rod 11 to buffer and shock-absorb the inner tank 12, improving its explosion stability and safety.
