Abstract
The utility model provides a silencer which comprises a silencer shell and a soundproofing material layer, wherein the soundproofing material layer is installed in the silencer shell. A plurality of holes are formed in the silencer shell of the outlet end of the silencer, wherein the holes are arranged in an array mode. The silencer has the advantages that effects of soundproofing and reducing noise can be further achieved by arranging the holes in an array mode in the silencer shell of the outlet end of the silencer. Soundproofing materials can be reduced and costs can be reduced. The size of the silencer is decreased.
Description
Technical field
The utility model relates to a kind of silencer.
Background technique
Existing silencing apparatus is generally impedance muffler, muffler shell is generally made by materials such as steel plate (pipe), corrosion resistant plate (pipe), alloy sheets (pipe), and in the air layer of shell, load the soundproof materials such as porosity rock wool material, namely utilize the resistive sound absorption principle of sound-absorbing material, reach the noise reduction sound-deadening purpose.Its acoustic absorptivity is high, and absorption band is wide, and the pressure loss is very little, and reproduced air-flow noise is low, and is easy to control.
The shortcoming of above-mentioned conventional silencing apparatus is that choosing the soundproof effect impact of soundproof material is larger, the soundproof effect manufacture cost that obtains is also higher, and the interpolation of soundproof material produces obstruction to the circulation of air in the silencing apparatus, so that the volume of the silencing apparatus of making itself is excessive.
The model utility content
The utility model provides a kind of silencing apparatus for addressing the above problem.
The technological scheme that the utility model technical solution problem adopts is that a kind of silencing apparatus comprises muffler shell and is arranged on the interior muffler material layer of muffler shell, is provided with the aperture of array on the muffler shell of described silencing apparatus outlet end.Better, the hole pitch between the aperture of described array is the integral multiple of described small aperture.The length of described muffler material layer is 1/2 to 2/3 of muffler shell length.
The beneficial effects of the utility model are, by the muffler shell at the silencing apparatus outlet end aperture of array are set, and can further obtain the effect of noise elimination noise reduction, and can reduce the use of muffler material, reduce cost, reduce the volume of silencing apparatus itself.
Description of drawings
Fig. 1, the structural drawing of embodiment's silencing apparatus.
Embodiment
A kind of silencing apparatus, its structural drawing is referring to accompanying drawing 1, comprise muffler shell 1 and be arranged on the interior muffler material layer 2 of muffler shell, be provided with the aperture 3 of array on the muffler shell 1 of silencing apparatus outlet end, the hole pitch that aperture by array of designs is 3 is the integral multiple of small aperture, also can merge into again large spray after can avoiding the interior air-flow of silencing apparatus by aperture 3, improve noise reduction.Simultaneously, the length of muffler material layer 2 is 2/3 of muffler shell 1 length.
Present embodiment arranges the aperture of array by the muffler shell at the silencing apparatus outlet end, can further obtain the effect of noise elimination noise reduction, and can reduce the use of muffler material, reduces cost, reduces the volume of silencing apparatus itself.
It should be noted that at last: above embodiment is only in order to illustrate the utility model and the described technological scheme of unrestricted the utility model; Therefore although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, it will be understood by those of skill in the art that still and can make amendment or be equal to replacement the utility model; And all do not break away from technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (3)
