Referring to FIG. 1, for the front view of air hose silencer specific embodiment provided by the utility model.
Air hose silencer provided by the present application, including muffler body 1 and flange 2, muffler body 1 include air hose ontology
11, the perforated plate 12 being connected with air hose ontology 11 and the sound absorption lining 13 being located between air hose ontology 11 and perforated plate 12,
Flange 2 and air hose ontology 11 are integrally formed structures.
It should be noted that air hose silencer provided by the present application is mainly used for solving flange 2 and air hose in the prior art
Gap is easy tod produce between silencer, leads to the problem that noise elimination effect is bad.For this purpose, method in air hose silencer provided by the present application
Orchid 2 is an integral structure with muffler body 1.
Specifically, muffler body 1 includes the air hose ontology 11 positioned at outer layer, the sound absorption lining 13 positioned at middle level and is located at
The perforated plate 12 of internal layer.
It is understood that air hose ontology 11 is primarily used to form ventilation shaft, gas is made to be flowed in ventilation shaft；It inhales
Sound lining 13 be mainly used for absorbing in air hose ontology 11 by air-flow noise, to achieve the purpose that control noise；Perforation
Plate 12 is mainly used for making sound absorption lining 13 be fixed in air hose ontology 11 while ensureing the sound absorption effect of sound absorption lining 13
Wall.
Sound absorption lining 13 is folded between air hose ontology 11 and perforated plate 12, and air hose ontology 11 and perforated plate 12 are fixed and connected
It connects, so that the position of sound absorption lining 13 is fixed.
Preferably, air hose ontology 11 is connected with perforated plate 12 by lightgage steel joist.
In addition, the application does not limit the specific size of air hose ontology 11.
It should be further noted that flange 2 is the total plate flange with the one of air hose ontology 11, that is to say, that flange 2 with
Air hose ontology 11 is integrally formed structures.When processing air hose ontology 11, direct pressing goes out flange 2.It is not only easy to process, and
Avoid the gap between flange 2 and air hose ontology 11.
In conclusion air hose silencer provided by the present application, in use, gas passes through from the pipeline of air hose ontology 11,
Under the action of absorbing sound lining 13, the noise of air-flow is absorbed via perforated plate 12 by sound absorption lining 13, therefore reaches control noise
Purpose.In addition, since flange 2 is the total plate flange with the one of air hose ontology 11, i.e., flange 2 and 11 one of air hose ontology at
Type avoids and uses blind rivet, rivet in the prior art or be bolted, therefore, do not stitched between flange 2 and air hose ontology 11
Gap reduces inleakage, while noise being avoided to be spread out of between flange 2 and air hose ontology 11, to make the air hose noise elimination utensil
There is preferable noise elimination effect.
Economy in view of the specific material of air hose ontology 11 and general sex chromosome mosaicism, on the basis of above-described embodiment
On, air hose ontology 11 includes metal material air hose ontology.
In order to make air hose ontology 11 that there is preferable mechanical performance, on the basis of above-described embodiment, metal material wind
Tube body is galvanized steel plain sheet air hose ontology.
It is understood that the corrosion resistance and screening characteristics of galvanized steel plain sheet are preferable, and convenient for forming, therefore, galvanized steel
Plate is relatively specific for flange 2 and is integrally formed with air hose ontology 11.
The problems such as in view of the intensity of galvanized steel plain sheet air hose ontology and convenient for formability, on the basis of above-described embodiment
On, the thickness range of galvanized steel plain sheet air hose ontology includes 0.6mm~1.5mm.
That is, plate thickness ranging from 0.6mm~1.5mm of air hose ontology 11 is formed, therefore, with air hose ontology 11
The thickness range of the flange 2 of plate is also 0.6mm~1.5mm altogether.
It is understood that the thickness of galvanized steel plain sheet air hose ontology is thicker, then the intensity of galvanized steel plain sheet air hose ontology is bigger,
However, the thickness of air hose ontology 11 is thicker, then it is more not easy to the forming of air hose ontology 11, therefore, considers air hose ontology 11
Intensity and formability problems, user the thickness of galvanized steel plain sheet air hose ontology can be selected in the thickness range of 0.6mm~1.5mm
Degree.
In order to increase the intensity of flange 2 and the transition position of air hose ontology 11, on the basis of above-mentioned any one embodiment
On, air hose ontology 11 is equipped with the reinforcing rib of the intensity for increasing transition position with the transition position of flange 2.
That is, air hose ontology 11 air inlet and air outlet end periphery be equipped with reinforcing rib, the one of reinforcing rib
Side is bonded the disconnected face of flange 2, to increase the intensity of air hose ontology 11 and the transition position of flange 2 by reinforcing rib.
Preferably, the number at least two of reinforcing rib, and all reinforcing ribs are uniformly distributed along the circumferential direction of air hose ontology 11.
In view of the cross sectional shape of air hose ontology 11, on the basis of above-described embodiment, the cross section of air hose ontology 11
Including rectangular cross section or circular cross section.
That is, the shape of the cross section of air hose ontology 11 includes rectangle or circle.That is, air hose ontology 11 includes square
Shape air hose ontology 11 or circular duct ontology 11.
It is understood that the resistance of circular duct ontology 11 is small, but the size of short transverse is larger, makes complicated；Square
The resistance of shape air hose ontology 11 is relatively large, but height dimension is small, makes simple.User can select according to actual conditions
It selects.
In view of the air inlet of air hose ontology 11 and the size of air outlet, on the basis of above-described embodiment,
The size of the air inlet of air hose ontology 11 is identical as the size of the air outlet of air hose ontology 11.
That is, when air hose ontology 11 is circular duct ontology 11, the caliber of air inlet and the caliber phase of air outlet
Together；When air hose ontology 11 is rectangular air duct ontology 11, the length and width of air inlet is identical as the length and width of air outlet.
In order to make sound absorption lining 13 have preferable sound absorption effect, on the basis of above-described embodiment, absorb sound lining 13
Including glass fiber, mild steel silk screen, felt or noise elimination cotton.
In order to make the noise in air-flow wear long orifice plate 12 into sound absorption lining 13, ensure the sound absorption properties of sound absorption lining 13
Can, on the basis of above-described embodiment, the range of the punching rate of perforated plate 12 includes 20%~30%.
It is understood that the punching rate of perforated plate 12 is higher, then the noise in air-flow is easier via 12 quilt of perforated plate
Sound absorption lining 13 is absorbed, and therefore, noise elimination effect is better.
In order to make the noise in air-flow is easier to be absorbed sound by sound absorption lining 13, the aperture for ensureing perforated plate 12 is needed,
Therefore, on the basis of above-described embodiment, the pore diameter range of perforated plate 12 includes 0.8mm~8mm.
It is understood that the aperture of perforated plate 12 is bigger, then noise elimination effect is better, however, the aperture of perforated plate 12 is got over
Greatly, then the intensity of perforated plate 12 is more influenced.
