Background
Noise is the sound produced when the sounding body does random vibration, and the sound is produced by the vibration of the object and is transmitted in a certain medium (such as solid, liquid and gas) in the form of waves, so that the noise pollution is generally called artificial. Since the industrial revolution, the creation and use of various mechanical devices have brought prosperous and advanced to human beings, but at the same time, more and more noises are generated, and the noise pollution is a serious environmental problem.
The traditional silencer has the advantages that the silencing area is only pure four-side silencing, and the area is relatively small. The mufflers of the same type are simpler to produce and manufacture, but have relatively large resistance loss, smaller section perimeter of the muffler and improved muffling effect. There is a need for a muffler with better performance.

The present invention is directed to a butterfly muffler for solving the above problems.
The utility model discloses a following technical scheme realizes above-mentioned purpose:
a butterfly-shaped silencer comprises an installation shell and a silencing body, wherein a certain number of installation supports are fixed in the installation shell through installation grooves, the mounting brackets penetrate through the cross section direction of the mounting shell, the mounting brackets are arranged at two ends of the mounting shell, a certain number of the silencing bodies are fixed between two corresponding mounting brackets through bolts, the silencing body comprises a flow guide cover, silencing cotton and a silencing framework, the flow guide cover is positioned at two ends, the two air guide covers are connected with the mounting bracket, the air guide covers are arranged to reduce the influence on a flow field as much as possible while eliminating noise, the noise eliminating framework is welded between the two air guide covers, the cavity of amortization skeleton is filled with the amortization cotton, the perpendicular welding has a certain amount of support horizontal poles between the installing support, the cross-sectional appearance of amortization skeleton is smooth transition butterfly form surface.
For further improving the silencing effect of the device, the mounting bracket is equidistantly arranged in the inner space of the mounting shell, and the silencing body is equidistantly arranged in the axis direction of the mounting bracket.
In order to further improve the silencing effect of the device, the distance between two adjacent mounting brackets is 2-2.5 times of the outer shape width of the silencing body, and the distance between two adjacent silencing bodies is 0.5-1.5 times of the outer shape height of the silencing body.
In order to further improve the silencing effect of the device, the supporting cross rods are arranged on the outer side of the mounting support, the number of the supporting cross rods is set according to the appearance height of the mounting shell, the appearance height of the silencing body is ensured to be 4-6 times the distance between the adjacent supporting rods, and at least one supporting cross rod needs to be arranged.
In order to further improve the silencing effect of the device, the silencing framework is made of a microporous material, and the silencing cotton is made of glass cotton with high hydrophobicity and high sound absorption rate, so that the silencing effect of the device is effectively improved.
In order to further improve the silencing effect of the device, the mounting shell is not limited to a metal frame shell, a civil wall and/or a ventilating duct is allowed to be used, the shape is not limited to a rectangle, other shapes are allowed to be adopted, and the length of the mounting bracket is correspondingly trimmed.
Has the advantages that: by optimizing the structure of the noise elimination body, the noise elimination body has larger section perimeter, so that the contact area of the noise elimination body and a noise medium is increased, and the noise elimination effect of the device is effectively improved; by adopting the combined structure, not only can the parts of the device be produced in batch, but also the easy transportation, the production manufacturability and the installation manufacturability of the device are improved.
