Abstract

The invention discloses an industrial fan capable of automatically controlling air volume, and particularly relates to the technical field of fans. The industrial fan comprises a first shell, a firstmotor, a rotating shaft and a plurality of fan blades, the first motor is fixedly arranged in the first shell, the rotating shaft is fixedly arranged on an output shaft of the first motor, and the plurality of fan blades are fixedly arranged at the outer end of the rotating shaft. The rotating shaft and the fan blades are arranged in the first shell, a first hollow circular ring is fixedly arranged at one side of the first shell, a through opening is formed at one side of the first hollow circular ring, a plurality of first ventilation openings are formed at the front end of the first hollow circular ring, and a control mechanism is arranged at the front end of the first hollow circular ring. Outdoor air enters a room through a second ventilation opening, meanwhile, indoor air can penetrate through a second hollow circular ring and the first hollow circular ring to circulate to the outside, air circulation is prevented from being hindered, and the ventilation efficiency and effect areeffectively guaranteed.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of fans, in particular to an industrial fan that can automatically control the air volume. Background technique [0002] Industrial fans refer to fans specially used for ventilation and fire-fighting high-temperature smoke exhaust in tunnels, underground garages, advanced civil buildings, metallurgy, factories and mines, etc. and other components. The following types are generally commonly used: centrifugal compressors, power station fans, general centrifugal fans, general axial fans, roots blowers, sewage treatment fans, high temperature fans, air conditioning fans, fire fans, mine fans, tobacco fans, grain fans , Marine fans, dust exhaust fans, roof fans, boiler blower induced draft fans, etc. [0003] The existing technology has the following shortcomings: the existing industrial fans usually install the motor and the fan blade in the fan casing, and then use it to drive the ai...
