Description

Technical Field

[0001] The utility model relates to the technical field of dust removal in coal mine production tunnels, and specifically relates to a dust removal device for coal mine production tunnels for safe production. Background Art

[0002] The dust removal device in coal mine production for safe production is to effectively control and reduce the dust pollution in the working environment, so as to protect the health and safety of miners. The dust removal device in the tunnel is an indispensable part of coal mine production for safe production. Through effective dust removal measures, a safer working environment can be provided for miners, and the incidence of occupational diseases can be reduced.

[0003] The prior art has the following deficiencies: In the prior art, the application number is 202022198819.7, which proposes a dust removal device for coal mine production tunnels for safe production, including the upper wall of the tunnel, upper mounting grooves, clamping grooves and a dust removal mechanism. The two upper mounting grooves are opened at the bottom surfaces of both ends of the upper wall of the tunnel, the two clamping grooves are opened on the surfaces of the inner cavities of the two upper mounting grooves away from each other, and the top parts of both ends of the dust removal mechanism are inserted into the inner cavities of the two upper mounting grooves and the two clamping grooves respectively. For this dust removal device for coal mine production tunnels for safe production, through the improvement of the dust removal device for coal mine production tunnels for safe production, first, the whole dust removal device can be made to have the functions of being easy to install and easy to maintain, which greatly reduces the labor intensity of the staff. Second, the dust removal effect of the coal mine production tunnels for safe production can be improved, which increases the working efficiency of the dust removal device. Finally, the dust can be quickly cleaned, thereby further improving the practicability of the dust removal device.

[0004] When the above equipment is used, structures such as a suction fan and a dust suction head are adopted to extract dust to achieve the effect of dry dust removal. Dry dust removal cannot suppress the dust rising on the ground of the tunnel. The existing wet dust removal will cause the tunnel to be in a wet state for a long time, resulting in muddy conditions. Moreover, for extremely fine dust particles, the capture effect of the wet dust collector is not as good as that of the dry dust collector. The dust removal device cannot perform wet and dry dust removal simultaneously, and the dust removal effect can be further improved. At the same time, the current coal mine tunnel storage device cannot perform different dust removal methods according to the actual environment and different requirements.
