Description
Technical field
The utility model relates to the noise elimination noise abatement field of air powered equipment, is specifically related to a kind of pipeline silencer.
Background technique
The device of the reduction noise on the air-flow path that silencing apparatus is mounted in air powered equipment (as blower, compressor etc.) or in inlet and exhaust system.Silencing apparatus can stop sound wave propagation, and allowing air-flow to pass through, is the effective tool of control noises.Although have known by many similar silencing apparatuss behave at present, the routine patent No. is: the patent of 201120331389.X, exactly by reaching the effect of noise elimination to the improvement in hush tube road.If but in the formal slight change of apparatus structure, soundproof effect will be made to be improved, therefore how its structure is improved, to improve soundproof effect, remain the technical problem being worth in prior art solving.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pipeline silencer.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of pipeline silencer, it comprises suction tude, steam outlet pipe, hush tube, and at least two silencing boards and a suppressor case, described housing cavity is divided into by silencing board and comprises the first chamber, second chamber and the 3rd chamber are at interior at least three chambers, described suction tude is communicated with the second chamber through housing with a dividing plate, described hush tube inlet end is communicated with the second chamber, body adjacent chamber in housing detours, and exhaust end is passed to the 3rd chamber, each chamber all arranges the hush tube that gas can be imported next chamber backward, until last chamber, described steam outlet pipe is positioned on the shell body wall of last chamber.
Preferably, a kind of pipeline silencer, it comprises suction tude, steam outlet pipe, hush tube and two silencing boards and a suppressor case, and described housing cavity is divided into the first chamber, the second chamber and the 3rd chamber by silencing board; Described suction tude is communicated with the second chamber through housing with a dividing plate; Described hush tube inlet end is communicated with the second chamber, and body detours after the first chamber in housing, exhaust end is passed to the 3rd chamber; Described steam outlet pipe is positioned on the shell body wall of the 3rd chamber.
Preferably, described hush tube inlet end sectional area sum is not less than suction tude sectional area.
Preferably, described steam outlet pipe sectional area is greater than suction tude sectional area.
The utility model has following beneficial effect:
1. the utility model uses pipeline shunt, and the principle of noise abatement of progressively eliminating the noise, make air-flow in hush tube in the roundabout process detoured, sound wave constantly weakens, and finally reaches desirable soundproof effect.
2. the utility model selects the mode that detoured in airtight chamber by hush tube, avoids the hush tube absorbing acoustic wave energy to be directly exposed to air and produces resonance, reduce sonic propagation of making an uproar further, make soundproof effect better.
3. the utility model hush tube inlet end sectional area sum is not less than suction tude sectional area, and steam outlet pipe sectional area is greater than suction tude sectional area, and such design reduces air resistance coefficient well, avoid air velocity too fast and produce secondary noise pollution.
Accompanying drawing explanation
Fig. 1 is schematic cross-section of the present utility model (arrow represents that gas flow is through direction).
Embodiment
Below in conjunction with accompanying drawing 1 and embodiment, the utility model is described in detail.
A kind of pipeline silencer, it comprises suction tude 4, steam outlet pipe 5, hush tube 3 and two silencing boards 2 and a suppressor case 1, and described housing cavity is divided into the first chamber 11, second chamber 12 and the 3rd chamber 13 by silencing board 2; Described suction tude 4 is communicated with the second chamber 12 through housing with a dividing plate; Described hush tube 3 inlet end is communicated with the second chamber 12, and body detours after the first chamber 11 in housing, exhaust end is passed to the 3rd chamber 13; Described steam outlet pipe 5 is positioned on the shell body wall of the 3rd chamber 13, and the gas importing the 3rd chamber 13 in hush tube 3 is discharged silencing apparatus.Hush tube 3 inlet end sectional area sum is greater than suction tude 4 sectional area, and steam outlet pipe 5 sectional area is greater than suction tude 4 sectional area, and such design reduces air resistance coefficient well, avoid gas flow rate too fast and produce secondary noise pollution.
Working principle of the present utility model:
First gas enters the second chamber 12 by suction tude 4, hush tube 3 inlet end is also communicated with the second chamber 12, the gas entering the second chamber 12 detours to the 3rd chamber 13 by numerous hush tubes 3 is roundabout again, then by steam outlet pipe 5, gas is sent suppressor case.By the mode that hush tube 3 detours in airtight chamber, both can reduce noise in long hush tube 3, and also avoid the hush tube 3 absorbing acoustic wave energy to be directly exposed to air and produce resonance, reduce sonic propagation of making an uproar further, make soundproof effect better.The application adding silencing board 2 grade in upper chamber all greatly reduces noise, makes the pneumatic noise flowing through the utility model pipeline silencer be down to lower level.
The above embodiment only have expressed mode of execution of the present utility model; it describes comparatively concrete and detailed; but therefore can not be interpreted as the restriction to the utility model the scope of the claims; in every case the technological scheme adopting the form of equivalent replacement or equivalent transformation to obtain, all should drop within protection domain of the present utility model.
