1. exporting in pressure shell and increasing wideband resistant noise-reducing device, which be composed of multiple resonant cavities, volume
It is larger, it is unfavorable for arrangement, and higher cost.It is not good enough to high-frequency noise sound absorption effect.
2. using impedance complex muffler, same volume is larger, higher cost, and muffler generally uses acoustical cotton as suction
Sound material, is unable to high temperature resistant, which generally uses in compressor inlet, since compressor delivery temperature is higher, the noise elimination
Device cannot be used in blower outlet.
And the muffler of the air-flow import and export installation of booster uses different structures now, and cost is relatively high, needs
Design a kind of inlet and outlet can muffler.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of booster pressure shell structures for being integrated with resistive muffler, can
To be mounted on the inlet and outlet of booster, noise reduction inner cavity is set inside muffler, and fills metallic fibrous layer, with porous plate
Noise reduction is combined, gas-flow radiation noise can be substantially reduced.
The technical solution adopted by the present invention to solve the technical problems is: providing a kind of pressurization for being integrated with resistive muffler
Device pressure shell structure, including pressure shell import/export pipe, the pressure shell import/export pipe include the air-flow connecting tube axially arranged with
Hush pipe, the inside of the hush pipe is coaxially arranged porous column shape plate, the outside of the porous column shape plate and hush pipe
Inner sidewall between form noise reduction inner cavity, the inside of the noise reduction inner cavity is filled with metallic fibrous layer, the noise reduction tube end
Insertion is equipped with for limiting the mobile split washer of porous column shape plate on air-flow import and export side wall.
As a supplement to the technical solution of the present invention, one layer is disposed on the outside of the porous column shape plate
Prevent metallic fiber from passing through the armour layer of porous column shape plate.
The metallic fibrous layer is set as single layer or multilayer laminate constructions.
Further, the armour layer is the porous plate being wrapped on the outside of porous column shape plate.
Further, the inner sidewall of the porous column shape plate is axially flushed with the inner sidewall of air-flow connecting tube.
The utility model has the advantages that may be mounted at increasing the present invention relates to a kind of booster pressure shell structure for being integrated with resistive muffler
The inlet and outlet of depressor can integrate after installation with the pressure shell of booster, and noise reduction inner cavity is arranged inside muffler,
And metallic fibrous layer is filled, and metal fiber polyporous material and perforated plate are combined into resonance sound-absorbing composite construction to height middle after pressure
Frequency noise has apparent erasure effect, can be substantially reduced gas-flow radiation noise；The releasable connection pipe with end cap is used in structure,
It does the diameter of hush pipe bigger, the more metallic fibrous layer of the number of plies can be placed, and metallic fibrous layer can
To be combined into graded composite metal fiber polyporous material with the metallic fibrous layer of multilayer different porosities or different fibre diameters,
With better sound absorption effect and the thickness of porous fibrous material can be reduced, further decreases muffler volume, is had fine
Promotional value.

Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
As shown in Figs. 1-2, the technical solution adopted by the present invention to solve the technical problems is: provide one kind be integrated with it is resistive
The booster pressure shell structure of muffler, including pressure shell import/export pipe 1, the pressure shell import/export pipe 1 includes axial arrangement
Air-flow connecting tube 2 and hush pipe 3, the inside of the hush pipe 3 is coaxially arranged porous column shape plate 6, the porous column
Noise reduction inner cavity is formed between the outside of shape plate 6 and the inner sidewall of hush pipe 3, the inside of the noise reduction inner cavity is filled with metallic fibrous layer
7, the air-flow of 3 end of hush pipe is imported and exported to be embedded on side wall at 8 and is equipped with for limiting opening for the movement of porous column shape plate 6
Mouth retaining ring 5.
The outside of the porous column shape plate 6 is disposed with one layer of armour layer for preventing metallic fiber from passing through porous column shape plate 6
4, armour layer 4 influences automobile reliability primarily to prevent metallic fiber from falling off from noise reduction inner cavity.
The metallic fibrous layer 7 is set as single layer or multilayer laminate constructions.
The armour layer 4 is the porous plate for being wrapped in 6 outside of porous column shape plate, and porous plate is not interfering air-flow to wear
Prevent metallic fiber from passing through under the premise of crossing.
The inner sidewall of the porous column shape plate 6 is axially flushed with the inner sidewall of air-flow connecting tube 2, is caused air flow through more
It is smooth.
When in use, one end of air-flow connecting tube 2 is inserted on air inlet or the gas outlet of booster pressure shell,
Air-flow enters in pressure shell import/export pipe 1 from air-flow connecting tube 2, by that can absorb making an uproar for high-temp waste gas when hush pipe 3
Sound can be combined by the porous plate of optimization metallic fiber porosity, string diameter, material thickness etc. and different punching rates, be reached pair
The application of different frequency noise.
As a kind of embodiment of the invention:
Muffler structure described in this patent can be by changing the filling length of inner cavity metallic fiber, thickness, and metal is fine
Material, the fibre diameter of dimension, metallic fiber filling porosity, punching rate of perforated plate etc. optimize muffler noise reduction frequency with
And erasure effect.The fibrous layer combination superposition erasure effect that metallic fibrous layer is changed to multilayer different parameters is more excellent；By metal fibre
Dimension layer and muffler inner wall stay a layer air layer, can reduce cost, also have preferable promotion to Middle and low frequency noise erasure effect.
Exemplar example:
Here length is exactly the axial length of noise reduction inner cavity, and thickness is exactly the radial thickness of noise reduction inner cavity.
3 exemplar muffler room temperature transmitting loss actual measurements are as shown in figure 3, the muffler of different parameters has different noise reductions
Effect, it is whole to have preferable erasure effect in wider frequency rate.
Pressing afterpulse noise frequency is 2200~3300Hz or so, and no muffler state-noise is obvious, installs volume production resistance additional
Muffler, muffler frequency are 2900 ± 100Hz, and noise is obviously improved.According to real steering vectors, muffler with respect to erasure effect compared with
Difference is exemplar 3, and the resistant noise-reducing device effect of volume production state, noise reduction effect has been fully achieved in the erasure effect of 2200~3300Hz
Fruit preferably exemplar 2, erasure effect is more preferable, can almost completely eliminate noise.
It is surveyed for the broadband noise vehicle muffler effect of 3000~10000Hz or so, installs volume production resistance additional and disappear
Sound device, muffler frequency are 2900 ± 100Hz, are not obviously improved to high frequency broadband noise, exemplar 2 and exemplar 3 exist to noise
The entire broadband noise band of 3000~10000Hz improves significantly, and illustrates that muffler of the present invention has broadband noise and obviously disappears
