Description
Technical field
The utility model is related to a kind of noise reduction arrangements with flaring structure, belong to noise reduction technical field.
Background technology
Muffler, be prevent sound ship and allow air-flow by a kind of device, be eliminate air power noise
Important measures.It is mainly mounted on the air powered equipment such as rows such as air blower, air compressor machine, boiler exhaust mouth, generator, water pump
The device of reduction noise on the gas channel of the larger equipment of gas port noise or in inlet and exhaust system.
Hush pipe arrangement in existing muffler is varied, such as each hush pipe arrangement in mobile muffler
And it is various, the utility model that is to say to be designed on basis herein.
The content of the invention
Shortcoming in for the above-mentioned prior art, the utility model are intended to provide a kind of noise reduction with flaring structure
Arrangement, it is novel in design reasonable, by improving the arrangement of each hush pipe in silencing cavity, it is achieved thereby that preferably noise reduction,
It is very useful.
To achieve these goals, the technical solution of the utility model：A kind of noise reduction arrangement with flaring structure,
It includes the silencing cavity with inlet and outlet, the silencing cavity by first partition, second partition be separated into successively first chamber,
Second chamber, the 3rd chamber, wherein, first silencing pot with the import sequentially passes through described second by the 3rd chamber
In partition plate, first partition to first chamber, the first partition is provided through in the first chamber and is connected to described second
Second silencing pot of chamber is provided through the second partition in the second chamber and is connected to the 3rd of the 3rd chamber
Silencing pot, the 3rd silencing pot and the second silencing pot position face and same central axis, while the cylinder of second silencing pot
Diameter is more than the cylinder diameter of the 3rd silencing pot, and has one to expand in the 3rd silencing pot end in the second chamber
Mouth structure, the maximum gauge of the flaring structure are more than the cylinder diameter of second silencing pot.
Further, the flaring structure distinguishes the outwardly extending loudspeaker of radial-axial for one with the 3rd silencing pot port
Mouth structure.
Further, it is respectively provided on the stack shell of first silencing pot in the first chamber, the second silencing pot
Several noise elimination vias.
The beneficial effects of the utility model：It is novel in design reasonable, by improving the arrangement of each hush pipe in silencing cavity, especially
It is that flaring structure between the second silencing pot and the 3rd silencing pot docks the flow direction for carrying out air-flow, realizes preferably noise reduction, it is non-
Chang Shiyong.
Description of the drawings
Fig. 1 is the structure schematic diagram of the utility model.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
A kind of noise reduction arrangement as shown in Figure 1 with flaring structure, including having the silencing cavity of inlet and outlet,
The silencing cavity is separated into first chamber 1, second chamber 2, the 3rd chamber 3 successively by first partition 10, second partition 11,
In, first silencing pot 12 with import sequentially passes through second partition 11, first partition 10 to first chamber 1 by the 3rd chamber 3
It is interior, it is provided through first partition 10 in the first chamber 1 and is connected to the second silencing pot 13 of second chamber 2, second chamber
Second partition 11 is provided through in room 2 and is connected to the 3rd silencing pot 14 of the 3rd chamber 3, the 3rd silencing pot 14 and second
13 position face of silencing pot and same central axis, while the cylinder diameter of second silencing pot 13 is straight more than the cylinder of the 3rd silencing pot 14
Footpath, and there is a flaring structure 141, the maximum of the flaring structure 141 in 14 end of the 3rd silencing pot in second chamber 2
Diameter is more than the cylinder diameter of the second silencing pot 13.
The outlet of the utility model is disappeared by the 4th silencing pot the 16, the 5th corresponded to through first partition 10, second partition 11
Cylinder record 15 is connected to outside silencing cavity.One complete vent gas treatment and silencing function are completed with this.Meanwhile flaring structure 141 is one
The outwardly extending bell-mouth structure of air of radial-axial is distinguished with 14 port of the 3rd silencing pot.
Finally, several noise eliminations are respectively provided on the stack shell of the first silencing pot 12 in first chamber 1, the second silencing pot 13
Via mutually rushes attenuation to reach preferably gas flow and noise.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is set forth the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion this specification content should not be construed as
Limitation to the utility model.
