The invention discloses a noise-reducing fan, which includes a fan body, the fan body is composed of a fan casing arranged on the top of the fan body and a base arranged at the bottom of the fan body, the top of the fan casing is provided with an air outlet, One side of the air outlet is provided with a filter, and the filter is embedded in the fan casing, and one side of the fan casing is provided with a fixing ring, and the fixing ring is fixedly connected with the fan casing, This kind of noise-reducing fan has good sound insulation effect and low cost. The set filter can greatly reduce the dust clogging internal devices, thereby prolonging the service life of the device. The set air filter can filter air and give The staff brings a good working environment, and a variety of noise reduction equipment is installed to effectively reduce the noise of the fan, so that the noise will not affect the health of the staff and the surrounding environment. It has a wide application prospect in the future.
Description
technical field [0001] The invention relates to the technical field of fans, in particular to a noise reduction 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 China's customary abbreviation for gas compression and gas conveying machinery. Usually, fans include ventilators, blowers, and wind power Y355 motors. Fans are mainly used in metallurgy, petrochemical, electric power, urban rail transit, textiles, ships and other national economies. Ventilation in various fields and places. In addition to traditional application fields, there will still be great development prospects in more than 20 potential market fields such as comprehensive utilization of coal gangue, technical transformation of new dry process clinker, energy saving in metallurgical industry, and comprehensive utilization of resources. [0003] However, the existing noise ...
