Mine air purification wind pressure device

The invention relates to a wind pressure device, in particular to a mine air purification wind pressure device. The technical problem of the invention is to provide the mine air purification wind pressure device capable of absorbing harmful substances and reducing dust. The mine air purification wind pressure device comprises a shell and at least two first connecting columns, and the first connecting columns are installed on the two sides of the top of the shell correspondingly; the air box is mounted on the upper side in the shell; the first rotating shaft is rotationally mounted at the lower part of the air bellow; the fan blade rotating wheel is installed in the middle of the first rotating shaft and located in the air box. The fan blade rotating wheel is driven by air to rotate, so that the air suction rotating fan is driven to rotate, air in a mine is sucked into the second reaction box through the air suction rotating fan, harmful substances in the air are absorbed through an activated carbon plate, and
