Dustproof ventilation equipment for coal mining

The invention relates to the field of ventilation equipment, in particular to dustproof ventilation equipment for coal mining. Comprising a filter pipe which is installed at the joint of a ventilation pipe and has the same inner diameter as the joint of the ventilation pipe, a middle pipe which is coaxial with the filter pipe and has two closed ends is arranged in the filter pipe, each side face of the middle pipe is provided with a horizontal first through hole, all the first through holes are distributed in a staggered mode, and rectangular filter plates perpendicular to the corresponding side faces are arranged in the first through holes. The outer ends of the filter plates penetrate through the corresponding second through holes and are located on the outer side of the filter pipe, a separation connecting structure is arranged between every two adjacent filter plates, sealing dust removal structures distributed in a bilateral symmetry mode along the corresponding filter plates are arranged in the second t
