Hush pipe with impurity removal function and good noise reduction effect

Abstract

The invention relates to a hush pipe with an impurity removal function and a good noise reduction effect. The hush pipe comprises a hush pipe body, an impurity removal mechanism, a connecting box anda noise reduction mechanism. The impurity removal mechanism comprises a filter screen, a rotating assembly, a transmission assembly and a cleaning assembly, the cleaning assembly comprises a driving shaft, a first bearing, a torsion spring and two cleaning plates, the noise reduction mechanism comprises a driving assembly, a support and two air exhaust assemblies, and each air exhaust assembly comprises an inflator, a piston, a first spring, a first connecting pipe and a second connecting pipe. According to the hush pipe with the impurity removal function and the good noise reduction effect, air exhaust work is carried out in the connecting box through the noise reduction mechanism, a vacuum state is formed in the connecting box, therefore, the speed of sound transmission is reduced, the noise reduction function is realized, the hushing effect is improved, impurity removal work is performed on water in the hush pipe body through the impurity removal mechanism, and the problem that impurities block the hush pipe body and affect the drainage capacity of hush pipe body is avoided.

Description

technical field [0001] The invention relates to the field of noise reduction and noise reduction equipment, in particular to a noise reduction pipe with a good noise reduction effect and a function of removing impurities. Background technique [0002] The silencer pipe is a pipe with a sound-absorbing function used in the drainage system. By reducing the collision between the water flow and the irregularly moving air and the pipe wall, the direction of the fluid is regulated, thereby reducing the noise and achieving the sound-absorbing effect. [0003] The sewage discharged from the existing silencing pipes usually contains more impurities, which increases the probability of clogging the existing silencing pipes and affects the circulation of sewage. Not only that, but the existing silencing pipes generally only reduce water flow and irregular movement. The collision of the air and the pipe wall is used to achieve the function of silencing, and the silencing method is relati...

Problems solved by technology

[0003] The sewage discharged from the existing silencing pipes usually contains more impurities, which increases the probability of clogging the existing silencing pipes and affects the circulation of sewage. Not only that, but the existing silencing pipes generally only reduce water flow and irregular movement. The collision between the air and the pipe wall is used to achieve the function of noise reduction, and the noise reduction method is relatively simple, so there is a defect that the noise reduction effect is poor, thus greatly reducing the practicability of the existing noise reduction pipe
