Background technique
Reactive muffler is that production connects resonant cavity etc. during acoustic propagation by the mutation of pipeline section or side and causes The change of impedance and generation sound can reflection, interference, so that the sound energy from silencer to external radiation is reduced, to reach noise elimination purpose Silencer.A kind of silencer that sound wave is reflected back into sound source.Impedance is lost using structures such as expansion and acoustic resonator in it It is equipped with reflected acoustic wave.It is mainly used for air compressor, automobile engine and other piston-engined air inlets and exhaust outlet, especially The case where suitable for low-frequency noise elimination and having high temperature, inflammable gas.The pressure drop that it generates air-flow is larger and causes to start Machine exhaust back pressure, this is a major issue in design.
Existing muffler structure is simple, and mostly fixed mechanism is installed, extremely inconvenient in actual use;It is existing Muffler disperses the flowing of sound wave, the effect of noise reduction is not ideal enough by simple plate hole.
Utility model content
The purpose of this utility model is to provide a kind of lower resistance silencers, have multi-layer material and improve muffler noise reduction Quality and the spoilage advantage that muffler is reduced by wind deflector, it is simple to solve existing apparatus structure, is not convenient to use and noise reduction The problem of effect difference.
To achieve the above object, the utility model provides the following technical solutions: a kind of lower resistance silencer, including shell and Bloop, one end of the shell offer air inlet, and the shell offers exhaust outlet away from one end of air inlet, it is described into The side that air port and exhaust outlet deviate from shell is respectively and fixedly provided with flange, and the inside of the shell is fixed with the first liner, the noise reduction There are two piece is set altogether, and two bloops are separately fixed at the inside two sides of the first liner, and the both ends of the bloop are fixed There is wind deflector, the inside of the bloop is fixed with the second liner.
Preferably, first liner is made of centrifugally glass-wool, glass fabric and liner orifice plate, and glass fabric Between centrifugally glass-wool and liner orifice plate.
Preferably, the external material of the bloop be orifice plate, second liner by layer glass fiber cloth holder from Heart mineral wool composition.
Preferably, the height of the wind deflector is less than the height of bloop, and wind deflector is in the shape of the letter V.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, the utility model is entered inside device in air-flow by air inlet by the first liner of setting and the second liner When, the weakening of wind-force is carried out by wind deflector, air-flow is effectively reduced to bloop) shock, the generation of noise is reduced, by the Centrifugally glass-wool, glass fabric and liner orifice plate in one liner make air-flow effectively reduce friction in flow process, lead to Cross bloop) in orifice plate, glass fabric and centrifugally glass-wool in the second liner reduce air-flow propagation rate, orifice plate makes air Enter the weakening for carrying out sound in the hole of multiple noise eliminations in the circulation process, is discharged, effectively reduces finally by exhaust outlet The propagation of sound.
