Abstract:
A fire-fighting smoke exhaust fan based on rotary filtering and automatic cleaning, the fire-fighting smoke exhaust fan comprising a fan housing (1), a smoke exhaust cylinder (2), a protective net (3), a first fixing plate (31), a second fixing plate (32), a smoke exhaust fan (33), a supporting rod (34), a dual-head electric motor (4), a water-intake rotating ring (41), a first fixing ring (5) and first metal wires (51). The smoke exhaust fan drives the smoke exhaust fan (33) to rotate by means of a rotary shaft of the dual-head electric motor (4) so as to remove dense smoke and smoke dust generated by an indoor fire, and the first fixing ring (5) and the smoke exhaust fan (33) rotate together, so as to drive the first metal wires (51) to filter out, in the rotation process thereof, the smoke dust carried in the dense smoke; meanwhile, water is sprayed out from first water spraying holes (52), such that when the dense smoke passes through the smoke exhaust cylinder, the sprayed water adsorbs the smoke dust carried in the dense smoke, solid particles and some harmful substances in the smoke dust are adsorbed by the water to form sewage droplets, the sewage droplets are attached to the first metal wires (51), and the smoke dust carried in the dense smoke is removed, thereby reducing harmful substances which are directly discharged into the air, and reducing environmental pollution.
