Abstract

The invention provides a filter device of a ventilator, relates to the technical field of factory ventilation equipment, and aims at solving the problem that during air exchange in factories, air mixed with dust is discharged to the outside, and consequently environment pollution is caused. The filter device comprises a ventilator body, an air inlet pipe and an air outlet pipe are arranged on thetwo sides of the ventilator body correspondingly, and the air inlet pipe is internally and sequentially provided with a dust fall assembly and a filter assembly in the air flow direction. The dust fall assembly comprises a plurality of communicating water supply rings rotationally connected into the air inlet pipe, a plurality of atomization sprayers arranged on each water supply ring in the circumferential direction of each water supply ring, and a drive piece for driving the multiple water supply rings to synchronously rotate. The multiple water supply rings are in communication through a water supply pipe, and the water supply pipe is a soft water pipe and communicates with a water source. The filter assembly comprises a limiting frame arranged in the air inlet pipe and filter cotton arranged on the limiting frame. The filter device has the beneficial effect that the dust can be filtered more completely.

Description

technical field [0001] The invention relates to the technical field of ventilation equipment for factories, in particular to a filter device for a ventilation fan. Background technique [0002] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers and various buildings; ventilation and drafting of boilers and industrial kilns, etc. Its working principle is: the blades are driven by the motor to rotate at high speed, and the blades accelerate the air when they rotate, so that the air obtains a certain acceleration, so that the gas obtains kinetic energy, and the airflow is decelerated and then discharged. In the factory, the air in the factory needs to be ventilated, and when the air in some dusty factories is exhausted, the air mixed with dust in the factory will be discharged into the atmosphere when using a fan, causing air pollution . [0003] The application document with the publication number CN105156341A discloses...
