Abstract:
A sprayer for coal mine dust fall, relating to the field of dust fall devices. The sprayer comprises: an outer shell (1), having at least one opening used for spraying water mist; a sprayer, placed in the outer shell (1) and spraying the water mist outwards through the opening; a plurality of water curtain nozzles (2), spraying water curtain lines outside the opening to block suspended dust; and a support, used for supporting the outer shell (1). The water curtain nozzles (2) surround the center of the opening and are distributed at equal intervals; the plurality of water curtain nozzles (2) are configured in a mode that the directions of the nozzles all point to the same point to form a water curtain having a round face or a conical face. Compared with the prior art, the sprayer for coal mine dust fall achieves the dust fall and also forms the water curtain to capture dust escaping from the water mist, so that a dust fall effect is improved.
