Description

technical field [0001] The invention relates to a fan muffler. Background technique [0002] Fan is a kind of general mechanical equipment with a wide range of applications. The production of electric power, mining, machinery, metallurgy, chemical industry and other industries cannot do without fans. The noise generated by the fan during operation is often a source of disaster affecting the health of workers and disturbing the environment. In particular, the aerodynamic noise radiated from the air inlet and outlet of the fan adjacent to the living area is the main factor that pollutes the environment and forms a public nuisance. [0003] Although some mufflers have been applied to fans on the market, these mufflers have complex structures and cumbersome assembly. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a fan muffler with simple structure and convenient installation. [0005] The te...
