Abstract
The invention discloses a kind of iris type casing muffler, belongs to muffler technical field, it includes casing, odd number sound gobo, muffler entrance, silencing end, even number sound gobo；One end of described casing is provided with muffler entrance, and the other end of casing is provided with silencing end；The epimere of described odd number sound gobo is uniformly provided with several through holes one；The hypomere of described even number sound gobo is uniformly provided with several through holes two.Its reasonable in design, it is easy to operate, volume and profile it is less, and noise reduction, good damping effect.
Description
Technical field：
The present invention relates to muffler technical field, and in particular to a kind of iris type casing muffler.
Background technology：
Muffler（(Muffler)）It is to prevent sound transmission and a kind of device for allowing air-flow to pass through, is the important measures for eliminating air power noise.Muffler is mounted in air powered equipment（The such as larger equipment of exhaust outlet noise such as air blast, air compressor machine, boiler exhaust mouth, generator, water pump）Gas channel on or inlet and exhaust system in reduction noise device.
At present, known muffler structure is damped to fluid by multi-cavity expansion to expand cavity configuration（Gas or liquid）Noise reduction and damping being carried out, needing noise reduction and damping effect can be just completed through multistage expansion circulation, operating efficiency is low, while silencer volume and profile are larger, is unsuitable for less installing space.
The audio frequency wavelength of low and medium frequency is longer, is difficult to accomplish complete noise reduction in noise reduction.
The content of the invention：
For the problems referred to above, the technical problem to be solved in the present invention is to provide the iris type casing muffler of a kind of reasonable in design, easy to operate, noise reduction and good damping effect.
A kind of iris type casing muffler of the present invention, it includes casing, odd number sound gobo, muffler entrance, silencing end, even number sound gobo；One end of described casing is provided with muffler entrance, and the other end of casing is provided with silencing end；The epimere of described odd number sound gobo is uniformly provided with several through holes one；The hypomere of described even number sound gobo is uniformly provided with several through holes two.
Preferably, described casing is cuboid, ellipsoid or other any shapes.
The present invention is to carry out filtering the propagation of sound and even number sound gobo blocking sound by several through holes one of odd number sound gobo, through filtration repeatedly, blocking, so as to reach the effect for abating the noise.
The muffler of the present invention is the multi-level muffler structure for filtering repeatedly blocking-up type.
During present invention operation, fluid（Gas or liquid）During by sound gobo, noise reduction and damping are carried out to fluid, the quantity of sound gobo can determine according to the requirement of noise reduction that the quantity of sound gobo is more in casing, and the efficiency of noise reduction and damping is higher.
Beneficial effects of the present invention：Its reasonable in design, it is easy to operate, volume and profile it is less, and noise reduction, good damping effect.
Description of the drawings：
For ease of explanation, the present invention is embodied as and accompanying drawing is described in detail by following.
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic diagram of odd number sound gobo in the present invention；
Fig. 3 is the schematic diagram of even number sound gobo in the present invention；
In figure：
Casing 1, odd number sound gobo 2, muffler entrance 3, silencing end 4, even number sound gobo 5, through hole 1, through hole 27.
Specific embodiment：
As shown in Figure 1 to Figure 2, this specific embodiment is employed the following technical solutions：It includes casing 1, odd number sound gobo 2, muffler entrance 3, silencing end 4, even number sound gobo 5；One end of described casing 1 is provided with muffler entrance 3, and the other end of casing 1 is provided with silencing end 4；The epimere of described odd number sound gobo 2 is uniformly provided with several through holes 1；The hypomere of described even number sound gobo 5 is uniformly provided with several through holes 27.
Preferably, described casing 1 is cuboid, ellipsoid or other any shapes.
This specific embodiment is to carry out filtering the propagation of sound and the blocking sound of even number sound gobo 5 by several through holes 1 of odd number sound gobo 2, through filtration repeatedly, blocking, so as to reach the effect for abating the noise.
The muffler of this specific embodiment is the multi-level muffler structure for filtering repeatedly blocking-up type.
When this specific embodiment is operated, fluid（Gas or liquid）During by sound gobo 2, noise reduction and damping are carried out to fluid, the quantity of sound gobo 2 can determine according to the requirement of noise reduction that the quantity of sound gobo 2 is more in casing 1, and the efficiency of noise reduction and damping is higher.
This specific embodiment reasonable in design, it is easy to operate, volume and profile it is less, and noise reduction, good damping effect.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.It should be understood by those skilled in the art that; the present invention is not restricted to the described embodiments; merely illustrating the principles of the invention described in above-described embodiment and specification; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements are both fallen within scope of the claimed invention.The claimed scope of the invention is by appending claims and its equivalent thereof
