Description

Technical Field

[0001] The invention relates to the technical field of fans, and in particular to a fan which is convenient for cleaning dust. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Fan is China's customary abbreviation for gas compression and gas delivery machinery. The fans usually mentioned include ventilators, blowers, and wind turbines. Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air intake of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances; drying and selection of grains, wind tunnel wind sources and inflation and propulsion of hovercraft, etc. Fans are mainly used in metallurgy, petrochemicals, electric power, urban rail transit, textiles, ships and other national economic fields and ventilation in various places.

[0003] The existing fans have certain drawbacks when in use. When the existing exhaust fans are in use, a large amount of dust is easily attached to the fan blades after long-term use. At the same time, a large amount of dust will also accumulate on the shielding net. If they are not cleaned, the air volume of the fan will be reduced, thereby reducing the working efficiency of the fan. When cleaning the existing fans, the staff needs to remove the shielding net, then remove the fan blades, and then clean the shielding net and the fan blades. This has high labor intensity and low cleaning efficiency. At the same time, the staff needs to frequently clean and maintain the fan, thereby increasing the maintenance cost of the fan.
