Technical Field

[0002] An explosion-proof dust collector refers to a dust collector applicable to occasions where there are flammable and explosive gases, water vapor, or fine dust in the air that can cause explosion or ignition. Dust explosion means that within the explosion limit range of dust, when encountering a heat source (open fire or temperature), the flame instantaneously spreads throughout the mixed dust space. The chemical reaction speed is extremely fast, and at the same time, a large amount of heat is released, forming a very high temperature and a large pressure. The energy of the system is converted into mechanical work and the radiation of light and heat, with strong destructive power.
[0003] An explosion-proof dust collector system with the Chinese authorized announcement number of CN216259882U realizes air circulation and utilization by connecting pipes and setting explosion isolation valves to pump out air, filter dust, and then send it back to the constant temperature workshop, reducing energy waste, and realizes secondary filtration in the later stage through a high-efficiency filter.
[0004] When in use, there are still some deficiencies. When the dust collector is in use, internal dust will explode. The pressure generated by the explosion will break the explosion-proof tank, which will cause injury to the staff, reducing the safety of the explosion-proof dust collector during use. And when an explosion occurs inside, the dust collector cannot be depressurized in time, and secondary dust explosion will also occur, resulting in limited practicability of the explosion-proof dust collector.

[0024] Embodiment, please refer to Figures 1-4 and the present utility model provides a technical solution:
[0025] An explosion-proof hammer-type explosion-proof device for an explosion-proof dust collector, comprising a bottom plate 1. A top of the bottom plate 1 is fixedly connected with an explosion-proof box 3. An outer surface of the explosion-proof box 3 is fixedly connected with an alarm lamp 4 and a controller 5 respectively. A center of the explosion-proof box 3 is fixedly connected with a dust collection box 14. A side groove 10 is formed in the explosion-proof box 3. A moving plate 12 is slidably connected in the side groove 10. A connecting spring 18 is elastically connected between the moving plate 12 and the side groove 10. A damping rod 19 is arranged in the connecting spring 18. A first sliding plate 13 is arranged on a side surface of the moving plate 12 through a rotating rod 11. Two ends of the rotating rod 11 are respectively hinged to the moving plate 12 and the first sliding plate 13. An inner wall of the explosion-proof box 3 is fixedly connected with a pressure sensor 16. A circular groove 20 is formed in the explosion-proof box 3. A rubber ball 21 is fixedly connected in the circular groove 20.
[0026] In this embodiment, as Figure 1 and Figure 2 shown, a second sliding plate 15 is slidably connected in the explosion-proof box 3. A side surface of the second sliding plate 15 is fixedly connected with a disc 22. A side surface of the disc 22 is fixedly connected with an elastic rod 17. The disc 22 extends into the circular groove 20 and abuts against the rubber ball 21. Both the second sliding plate 15 and the first sliding plate 13 are arranged on a side surface of the dust collection box 14. A bottom of the dust collection box 14 is fixedly connected with a pressure relief pipe 6. An electric valve 7 is arranged outside the pressure relief pipe 6. The pressure relief pipe 6 is communicated with the dust collection box 14. A top of the explosion-proof box 3 abuts against a cover 8. A top of the cover 8 is fixedly connected with a dust inlet pipe 9. The dust inlet pipe 9 is communicated with the explosion-proof box 3.
[0027] Wherein, the generated impact force pushes the first sliding plate 13 and the second sliding plate 15 to move. By pushing the rotating rod 11 through the first sliding plate 13, the moving plate 12 is further moved in the side groove 10, so that the moving plate 12 abuts against the connecting spring 18. At the same time, the second sliding plate 15 drives the disc 22 and the elastic rod 17 to move, so that the disc 22 abuts against the rubber ball 21, thereby reducing the impact force received by the explosion-proof box 3 and avoiding the explosion of the explosion-proof box 3.
[0028] In this embodiment, as Figure 3 and Figure 4 shown, both the alarm lamp 4 and the controller 5 are electrically connected to the pressure sensor 16. The controller 5 is electrically connected to the electric valve 7. A bottom of the bottom plate 1 is provided with universal wheels 2.

The plurality of rubber balls 21 are evenly distributed at equal angles in the circular groove 20. Sizes of the plurality of rubber balls 21 are the same.
[0029] Wherein, when a dust explosion occurs, the pressure of the first sliding plate 13 and the second sliding plate 15 can be monitored by the pressure sensor 16, and the signal is transmitted into the controller 5, so that the electric valve 7 is automatically opened, thereby relieving the pressure inside the explosion-proof box 3 and avoiding a secondary dust explosion, and improving the safety during the use of the dust collector.
[0030] Working process of the utility model: When the heavy hammer type explosion-proof device of the explosion-proof dust collector designed by this solution is working, dust enters the dust collection box 14 through the dust inlet pipe 9. When a dust explosion occurs, the thrust generated by the explosion respectively pushes the first slide plate 13 and the second slide plate 15 to move. When the first slide plate 13 moves, it drives the moving plate 12 to slide in the side groove 10 through the rotating rod 11, and then the connecting spring 18 is abutted by the moving plate 12, so as to buffer the impact force of the first slide plate 13 on the inner wall of the explosion-proof box 3. At the same time, when the second slide plate 15 moves, it drives the disc 22 and the elastic rod 17 to move, so that the surfaces of the disc 22 and the rubber ball 21 are abutted, and the elastic rod 17 is abutted against the circular groove 20, so as to reduce the impact force of the second slide plate 15 on the inner wall of the explosion-proof box 3 and avoid the explosion-proof box 3 from bursting. At the same time, when the first slide plate 13 and the second slide plate 15 move, they will squeeze the pressure sensor 16, so that the alarm lamp 4 flashes, and at the same time, an electric signal is transmitted to the controller 5, and the switch of the electric valve 7 is opened through the controller 5 to relieve the pressure inside the explosion-proof box 3 and avoid the explosion of the explosion-proof box 3 again.
