Description

Colliery safety in production gallery dust collector

Technical Field

The utility model relates to the field of coal mine safety, in particular to a dust removal device for a coal mine safety production tunnel.

Background

When the coal seam is far from the ground surface, a tunnel is usually dug to the underground, so that the coal is a mineworker coal mine. When the coal seam is very close to the earth surface, the coal is generally excavated by directly stripping the earth surface, which is an open pit coal mine. The vast majority of coal mines in China belong to underground coal mines. Coal mines encompass a large area above ground and below ground as well as associated facilities. The coal mine is a reasonable space excavated by human beings when excavating geological layers rich in coal, and generally comprises a roadway, a well cave, an excavation surface and the like, because the coal mine is exploited underground, the safety of the underground mine is particularly important, more dust can be generated in the coal mine exploitation process, and the dust removal treatment is needed to avoid the dust explosion phenomenon caused by more dust.

The patent document with the publication number of CN213269960U in the prior art provides a dust removal device for a coal mine safety production tunnel; the device arranges the dust removing nozzles for removing dust in the inner cavities of the protection grooves at two sides of the coal mine tunnel, when a machine passes through the supporting bottom plate, the supporting bottom plate can be pressed downwards, the dust removing spray head extends out of the inner cavity of the protecting groove by utilizing the lever principle, meanwhile, the bottom end of the contact pressure rod presses and contacts on the contact switch to enable the water suction pump to start working, so that water in the reservoir can be sprayed out through the dust removal spray head to realize water mist dust removal, when the machine leaves, under the elastic force of the return spring, the dust removing spray head can be automatically recovered into the inner cavity of the protection groove, and the bottom end of the contact pressure lever leaves the contact of the contact switch to stop the work of the water pump, so that the water mist dust removal is realized when the machine works, and when the machine does not work, and stop work reduces the waste to the water resource, and can realize the protection to the dust removal shower nozzle, avoids influencing normal dust removal because of the damage of dust removal shower nozzle.

Although the device has more beneficial effects, the following problems still exist: the device design is too complicated for installation and maintenance are very inconvenient, and activity arm-tie and support arm-tie outer end all rotate on the pitch arc, lead to the shower nozzle mounting panel when the up-and-down motion, and then lead to reset spring when concertina movement, also can produce and control the skew, and this has aggravated reset spring's fatigue undoubtedly, leads to its life to reduce. In view of this, we propose a colliery safety in production gallery dust collector.
