The invention relates to the technical field of
coal mine dust removal, in particular to a
coal mine automatic spraying dust removal device. A dust interception mechanism and a
sewage precipitation mechanism are arranged above a mounting bottom plate, the dust interception mechanism is used for adsorbing, collecting and intercepting dust in a
coal mine tunnel by using water, and the
sewage precipitation mechanism is used for filtering and separating a mixture formed by the dust and the water; Therefore, water can be recycled in the dust intercepting mechanism. The dust interception mechanism comprises an interception net mechanism, a spray
pipe mechanism and an adsorption cotton mechanism which are sequentially fixed on the mounting bottom plate, the
sewage precipitation mechanism comprises a mounting box body, and a precipitation chamber, a
water collection chamber and a
water storage chamber through which a mixture formed by dust and water sequentially flows are arranged in the mounting box body. The technical scheme is used for solving the problems that in the prior art, a spraying dust removal
system is high in
water source consumption,
water resources are wasted, the dust removal effect is poor, and the dust removal requirement in a coal
mine tunnel cannot be met.
