Cabinet type self-cleaning noise reduction fan

Abstract

The invention discloses a cabinet type self-cleaning noise reduction fan and relates to the technical field of fans. The cabinet type self-cleaning noise reduction fan comprises a cabinet body, and agalvanized plate is fixedly installed on the inner wall of the cabinet body. According to the cabinet type self-cleaning noise reduction fan, the cabinet body, the galvanized plate, a macromolecule damping material plate, a porous silencing plate, a telescopic sleeve, a spring, a holding base, a fan body, an impeller, an air outlet pipe, a silencer, a foam cylinder and an air inlet are used in cooperation, the galvanized plate achieves the functions of attractiveness and rust prevention, and the macromolecule damping material plate has the functions of sound absorption, heat insulation, shockprevention and the like. The porous silencing plate is made of a silencing material, the effect of noise reduction can be further achieved, and the noise generated when the impeller operates can be reduced through the arrangement of the foam cylinder. Through the arrangement of the telescopic sleeve, the spring and the holding base, vibration generated when the fan body operates can be reduced, noise generated by the fan body is further reduced, and therefore the noise can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to a cabinet-type self-cleaning and noise-reducing fan. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the customary abbreviation for gas compression and gas conveying machinery in China. Usually, fans include ventilators, blowers, and wind generators. Fans are widely used in factories, mines, tunnels, cooling towers, vehicles, ships, and buildings. , Dust extraction and cooling, ventilation and induction of boilers and industrial furnaces, cooling and ventilation in air conditioning equipment and household appliances, drying and selection of grain, wind tunnel wind source and inflation and propulsion of hovercraft, etc. [0003] At present, some cabinet fans will vibrate during operation, which makes the noise of the fan loud.

AI Technical Summary

Problems solved by technology

[0003] At present, some cabinet fans will vibrate during operation, which makes the noise of the fan loud. After a long period of vibration, the impeller wears out, thus reducing the service life of the fan. On the other hand, when the fan is in operation, Passing through the air inlet will cause a lot of dust to enter the cabinet, which will easily affect the performance and service life of the fan, so it needs to be disassembled and cleaned frequently, but some cabinet fans are complicated to disassemble and difficult to install
