A fan silencer for a dust collector

Abstract

The invention discloses a fan muffler for a dust remover, which belongs to the field of anti-noise equipment. The fan muffler for the dust remover comprises an outer shell, an inner shell, noise reduction cotton arranged between the outer shell and the inner shell, noise reduction plates, multiaperture sound absorption pipes and a filter screen, wherein an air outlet and an air inlet are respectively arranged on two ends of the inner shell; two or more noise reduction plates are sequentially arranged in the inner shell and are vertical to an air inlet direction; and a plurality of multiaperture sound absorption pipes vertically penetrate through the noise reduction plates and are uniformly arranged; and the filter screen is arranged in the air inlet. According to the fan muffler for the dust remover, the air power noise can be gradually eliminated by utilizing the multiple layers of noise reduction plates, the noise reduction cotton can be effectively prevented from adsorbing dust, the service life of the muffler is prolonged, and meanwhile, the fan muffler for the dust remover is simple in structure, good in erasure effect, and low in manufacturing cost.

Description

technical field

[0001] The present invention relates to a muffler, more specifically, to a fan muffler for a dust collector. Background technique

[0002] A muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is installed on the air flow channel of aerodynamic equipment (such as blower, air compressor, boiler exhaust, generator, water pump and other equipment with high exhaust noise) or in the intake and exhaust system to reduce noise. device. The principle is: the muffler is equipped with a porous sound-absorbing material. When the sound wave enters the muffler, a part of the sound energy is rubbed in the pores of the porous material and converted into heat energy consumption, which finally plays a role in weakening the sound wave. The fan in the dust removal equipment system runs at a high speed and generates a lot of noise, which is easy to cause noise pollution....
