Wind power expander type strong power air curtain dust controlling device

The invention discloses a wind power expander type strong power air curtain dust controlling device. The wind power expander type strong power air curtain dust controlling device comprises a base and an air curtain generator arranged on the base. The air curtain generator comprises a first fixing plate, a second fixing plate and an air spraying mechanism clamped between the first fixing plate and the second fixing plate. The first fixing plate, the second fixing plate and the air spraying mechanism are fastened through a plurality of screws. The air spraying mechanism comprises a front disc and a rear disc, a gap is formed in a semicircular covering position of the front disc and the rear disc, the rear disc is internally provided with a circular air chamber and an air spraying chamber, the air wall of the air chamber is connected with the air chamber through a diverting port and an air groove, the first fixing plate and the front disc are provided with a round air inlet, and the air inlet is communicated with the air chamber. A small amount of underground pressure wind is adopted as power, a powerful air curtain is formed through the fluid mechanics principle, a protection layer is formed in front of an operator, dust invasion is prevented, power is not needed, and therefore potential safety hazards of electric appliances under a coal mine are avoided.
