Background
Roots blower is a typical positive displacement blower, which is a machine that relies on input mechanical energy to raise the pressure of the gas and discharge the gas, and is a driven fluid machine. Compared with centrifugal blower, it has the advantages of high pressure head, less flow resistance, stable air supply, etc. but has the common disadvantages of low efficiency and high noise in the use process. Roots blower is widely used for ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and air induction of boilers and industrial kilns. The fan generates larger noise, so that the labor condition is deteriorated, and the living environment is polluted, and people increasingly pay attention to the noise of the fan.
At present, roots fans contain various noise sources, wherein aerodynamic noise radiated by inlet and outlet parts is strongest, and particularly, the fans with larger volumes can generate strong noise in the running process, so that working conditions of workers and living environments of surrounding residents are influenced. The Chinese patent with publication number CN111927781A discloses a middle-low frequency muffler for a Roots blower, which has poor noise reduction effect as a common Roots blower muffler and cannot effectively achieve the noise reduction effect.

The utility model provides a Roots blower muffler, which overcomes the defects of the prior art and can effectively solve the problem of poor noise reduction effect of the traditional Roots blower muffler.
The technical scheme of the utility model is realized by the following measures: the utility model provides a roots fan muffler includes muffler casing and amortization module, be equipped with the installation cavity that link up about in the muffler casing, be equipped with a plurality of amortization module in proper order from left to right in the installation cavity, amortization module includes amortization net cone, left amortization net ring, right amortization net ring and amortization layer, amortization net cone is big left and right little awl cylindric, amortization net cone left end outside fixed mounting has left amortization net ring, amortization net cone right-hand member outside fixed mounting has right amortization net ring, be equipped with the amortization layer between amortization net cone outside and the muffler casing inboard corresponding position of position between corresponding left amortization net ring and the right amortization net ring.
The following are further optimizations and/or improvements to the above-described inventive solution:
The noise reduction layer can be sound absorption cotton.
The silencer comprises a silencer shell, and is characterized by further comprising a left reducing joint, a right reducing joint and a connecting flange, wherein the left reducing joint is fixedly arranged at the left end of the silencer shell, the right reducing joint is fixedly arranged at the right end of the silencer shell, and the connecting flange is fixedly arranged at the outer side of the left end of the left reducing joint and the outer side of the right end of the right reducing joint.
Six silencing modules can be sequentially arranged in the installation cavity from left to right.
The utility model has reasonable and compact structure and convenient use, and is convenient to be installed into or taken out from the silencer shell by adopting the modularized silencing module; through loading into a plurality of amortization modules, change the muffler casing installation cavity of straight hole shape into a plurality of continuous round platform holes to strengthen the amortization effect, have stable, cooling and water conservancy diversion effectual characteristics.
