Abstract
The utility model relates to the field of underground dedusting of coal mines, specifically to a moderate air pressure air drilling dedusting system. As one of soft coal seam drilling methods, moderate air pressure air drilling has a most serious problem of difficult control of coal dust on work sites. Along with increase of orifice depth, exhausted pulverized coal is further broken through a long-distance deslagging process; the coal dust doses not diffuse easily because of narrow space of underworkings of the coal mines and thus poses a great threat to health of workers; and a mass of the coal dust and certain gas contained in compressed air also bring tremendous potential safety hazards. The moderate air pressure air drilling dedusting system comprises a duct collector, a primary dedusting device and a fine filter collector; the dust collector is connected with an orifice pipe and is connected with the primary dedusting device through a dust exhaust rubber pipe; and the primary dedusting device is connected with the fine collector through a dust exhaust rubber pipe. The moderate air pressure air drilling dedusting system has high dust collecting and dedusting efficiency and is convenient for spot arrangement, transfer and movement with a separated type structure.
