Abstract

The invention discloses a sprayer for coal mine dust fall, and belongs to the field of dust fall devices. The sprayer used for coal mine dust fall is characterized by comprising an outer shell, a sprayer body, multiple water curtain nozzles and a support; the outer shell is provided with at least one opening used for spraying water mist; the sprayer body is placed in the outer shell and sprays thewater mist outwards through the opening; the multiple water curtain nozzles spray water curtain lines outside the opening to block suspended dust; and the support is used for supporting the outer shell; and the water curtain nozzles surround the center of the opening and are distributed at equal intervals, and the multiple water curtain nozzles are configured in the mode that the directions of the nozzles all point to the same point to form a water curtain with a round face or a conical face. Compared with the prior art, the sprayer for coal mine dust fall has the advantages that the water curtain is formed to capture the dust escaping from the water mist while the dust fall is achieved, so that the dust fall effect is improved.

Description

technical field [0001] The invention relates to the field of dust suppressors, in particular to a sprayer for coal mine dust suppression. Background technique [0002] In mining engineering, mining work will produce a large amount of dust, and coal miners will inhale the floating dust in the mine for a long time, which will cause lung lesions; coal dust is in a suspended state in the air, and when it reaches a certain concentration or is affected by shock waves, it will explode. security risks. Therefore, the sprayer used for coal mine dust reduction is often used in mining, and the dust in the air is adsorbed and settled by spraying in the air. [0003] There are already many kinds of sprayers used for dust reduction in coal mines on the market, but most of the existing sprayers only unilaterally carry out dust reduction through spraying. In this case, part of the dust is not combined with water mist, and it will still be blown into the air again. Causes the problem of in...
