Description
Technical field
The utility model relates to the technical field of silencing apparatus, particularly a kind of Novel silencing device.
Background technique
Silencing apparatus allows air-flow to pass through, but can stop or reduce a kind of device of sound transmission, is the important measures eliminating air power noise.Silencing apparatus can stop sound wave propagation, and allowing air-flow to pass through, is the effective tool of control noises.Diesel engine can send larger noise when operating, and produces noise pollution, not only can have influence on the rest impact life of resident, and people's ear-drum discomfort can be caused to cause Hiccough and deaf etc., so we need to eliminate as much as possible or the generation of noise decrease.
Model utility content
For solving the problem, the purpose of this utility model is to provide the Novel silencing device that a kind of noise cancellation effect is good, easy to use, moulding is small and exquisite.
For achieving the above object, the technical solution of the utility model: a kind of Novel silencing device, comprise housing, particle layer, airscoop shroud, air leaving cover, air pipe, sound-absorbing material and filter plate, described housing is docked by left and right two halves case seizing type and forms, shell inner surface is coated with intensive particle layer, a mounting hole is all had with back side under the front of housing, air pipe is snap-in to be fixed between two mounting holes, air pipe is bent into some layers, and filter plate is equipped with between the air pipe inwall that every layer is communicated with position, all with one deck sound-absorbing material on the inwall of air pipe and outer wall, the front port integral type of air pipe is provided with airscoop shroud, and rear port integral type is provided with air leaving cover, airscoop shroud and air leaving cover are all located at outside housing, airscoop shroud is connected with the outlet pipe of diesel engine.
As preferably, the inwall of described air pipe and the sound-absorbing material of outer wall can be spongy layer or layer of fibers.
As preferably, described airscoop shroud and air leaving cover can exchange use mutually, and air leaving cover is connected with the outlet pipe of diesel engine.
The utility model has the advantage of, easy to use, airscoop shroud and air leaving cover all can be connected with outlet pipe, plug and play, multilayer quieter manner, to greatest extent less noise, can be directly installed on outlet pipe, compact volume and convenience.
