Description

Technical Field

[0001] The utility model relates to the technical field of muffler protection, in particular to a protection net for a large-scale muffler. Background Art

[0002] A silencer, also known as a muffler or a silent device, is a device used to reduce noise from mechanical equipment, engines, aerodynamics, etc. The main function of a silencer is to eliminate noise, protect the working environment and personnel health. A silencer is usually made of carbon steel or stainless steel. Types include resistive silencers, resistant silencers, and impedance composite silencers. Resistive silencers mainly absorb the energy of sound waves through the porous material inside and convert it into heat energy, while resistant silencers use a combination of tubes and chambers with a sudden interface, similar to an acoustic filter, to reflect or absorb sound waves of a specific frequency, thereby achieving the purpose of noise elimination. Mufflers are widely used in the automotive, electric power, petrochemical, metallurgy, mining, textile and other industries to control noise pollution.

[0003] Due to the usage characteristics of the silencer, a large amount of heat will be generated during use. Although there is a protective net to protect it, a small amount of impurities in the air will still penetrate the protective net and adhere to the outer wall of the silencer, thereby affecting the normal heat dissipation effect of the silencer. If it is not cleaned in time, it will easily cause damage to the silencer over time. Moreover, the protective nets currently used are usually of specific sizes. When there are slight differences in the size of the silencer, the fixing of the protective net will not be firm, thereby affecting the protection effect. Therefore, a protective net for large silencers is proposed to solve the above technical problems. Utility Model Content
