DETAILED DESCRIPTION

[0016] The utility model will be further detailed below in conjunction with the drawings and specific embodiment, but is not limited to this, any in the basic spirit of the utility model embodiment improvement or replacement, still belongs to the range that the utility model wants to protect.

[0017] As Figure 1 The utility model discloses an explosion -proof dust collector, including box 1, be provided with waste gas import 2 and filter export 3 on the box 1, be provided with anti -explosion piece 4 on the box 1 side wall, the box 1 outside is also provided with protective cover 5, the protective cover 5 covers the outside of anti -explosion piece 4, the inside of protective cover 5 is communicated with the outside, the protective cover 5 is also provided with spray pipe 6 in.

[0018] When the pressure in the box 1 is too big, the anti -explosion piece 4 explodes, so that the pressure in the box 1 is released, plays the effect of pressure relief, avoids the explosion of the box 1, and the serious accident occurs, and the fragment produced when the anti -explosion piece 4 explodes can be kept off by the protective cover 5, and will not randomly break out and diffuse to the four directions, avoid the influence to the nearby operator or other equipment, improve the safety performance. Meanwhile the dust in the box 1 spills over and diffuses after the anti -explosion piece 4 explodes, and the spray pipe 6 can wet the dust that spills over, makes dust subsides, alleviates the phenomenon of dust raising, avoids the pollution to the environment.

[0019] To further enhance safety, in some embodiments, the number of explosion-proof plates 4 is multiple, and the multiple explosion-proof plates 4 are evenly distributed on the side of the housing 1.

[0020] Specifically, such as Figure 2 As shown, the protective cover 5 includes a cover plate 51, side plates 52, and baffles 53. The cover plate 51 is vertically installed on the side wall of the housing 1. The side plates 52 are disposed on both sides of the cover plate 51. The baffles 53 are connected to the side plates 52 on both sides, and the upper part of the baffles 53 is connected to the cover plate 51. The cover plate 51, side plates 52, baffles 53, and the side wall of the housing 1 together form a protective cavity. The bottom of the protective cavity is open, and the explosion-proof disc 4 and the protective cover 5 are located inside the protective cavity. The protective cover 5 surrounds the outside of the explosion-proof disc 4 and has an open bottom, which can effectively block the fragments that fly out when the explosion-proof disc 4 explodes. At the same time, the open bottom allows communication with the outside world and does not affect the pressure relief function of the explosion-proof disc 4 after explosion.

[0021] like Figure 1 As shown, in some embodiments, the exhaust gas inlet 2 is equipped with a one-way explosion-proof valve 8. In the event of an explosion in the housing 1, the one-way explosion-proof valve 8 can cut off the connection between the exhaust gas inlet 2 and the housing 1, preventing any impact on upstream equipment in the event of an abnormality in the housing 1, thus further improving the safety of the equipment.

[0022] As shown in the figure, in one embodiment, the filter outlet 3 is equipped with a pressure relief valve 7. When the pressure at the filter outlet 3 is too high, the pressure relief valve 7 can automatically open to relieve pressure, further improving the safety of the equipment.

[0023] In order to reduce the noise generated during equipment operation, in some embodiments, the filter outlet 3 is connected to an exhaust pipe 9, and a silencer 10 is provided on the exhaust pipe 9.

[0024] As shown in the figure, in order to facilitate the collection and discharge of the dust filtered inside the housing 1, a conical dust collection hopper 11 is provided at the bottom of the housing 1 in this utility model, and a discharge valve 12 is provided at the bottom of the dust collection hopper 11.

[0025] To further enhance the safety performance of the equipment, in some embodiments, a nitrogen nozzle (not shown in the figure) is also installed inside the ash collection hopper. In the event of a combustion risk within the chamber, nitrogen can be introduced into the chamber through the nitrogen nozzle to dilute the oxygen concentration, thereby preventing combustion or even explosion.

[0026] The above-described specific embodiments further specifically describe the purposes, technical solutions and beneficial effects of the present application, and it should be understood that the above-described specific embodiments are merely examples of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
