Description

technical field [0001] The invention relates to the technical field of ventilation equipment, in particular to a fire-fighting smoke exhaust fan. Background technique [0002] The patent number is CN201821668675.3 for a rapidly adjusting blade exhaust fan. The utility model discloses a rapidly adjusting blade exhaust fan, comprising a volute, an air outlet on the side of the volute, and an adjustment port on one end face of the volute , An exhaust pipe is installed on the outside of the adjustment port, and an air inlet is opened in the exhaust pipe. The end face of the other side of the volute is sleeved with the first rotating shaft. The pulley drives the impeller to rotate through the first rotating shaft, and the air is drawn into the volute from the air inlet, and then discharged from the air outlet. The blade rotates to change the angle of the blade, and then the exhaust pipe is installed, so that the exhaust fan can meet the needs of different exhaust air volumes. H...
