A new type of dust-proof fan with noise reduction function

Abstract

The invention discloses a novel dust-proof fan with noise reduction function, which relates to the technical field of ventilation and includes an axial flow fan and an air inlet assembly. One end of the axial flow fan is an air inlet end, and the other end is an air outlet end; The air inlet end of the axial flow fan is equipped with an air intake hood, and an air intake assembly is installed at one end of the air induction hood, and the air induction hood and the air intake assembly are connected by a clamping assembly. , use the inclined dust baffle to block and change the direction of the air entering the dust cover, so that the air entering the dust cover will contact the dust baffle at the first time, and the dust baffle can carry air At the same time, through the arc-shaped filter cover, the dust in the air entering the dust cover can be filtered to further reduce the dust entering the axial flow fan , to prevent dust from sticking to the fan impeller.

Description

technical field [0001] The invention relates to the technical field of ventilation, in particular to a novel dustproof fan with noise reduction function. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades. Ordinary axial flow fans can be used for ventilation in general factories, warehouses, offices, residential buildings, etc., and can also be used for air coolers and evaporators. , condenser, spray drop, etc., there are also mining axial flow fans, anti-corrosion and explosion-proof axial flow fans adopt anti-corrosion materials and explosion-proof measures, and match explosion-proof motors, which can be used to transport explosive, volatile and corrosive gases , when the impeller of the axial flow fan rotates, the gas enters the impeller axially from the air inlet, is pushed by the blades on the impeller to increase the energy of the gas, and then flows into the guide vane, whic...

AI Technical Summary

Problems solved by technology

[0004] 1. The long-term use of the axial flow fan will cause more dust to stick to the fan impeller, and the fan impeller needs to be disassembled and cleaned. Repeated disassembly and installation of the fan impeller will reduce the service life of the axial flow fan;

[0005] 2. When the axial flow fan is in use, there is a lot of noise. When it is used in a quiet place, it will disturb the environment and cause noise pollution;
