Description
technical field:
The utility model relates to baffler technical field, is specifically related to a kind of diaphragm type casing baffler.
background technique:
Baffler ((Muffler)) is a kind of device stoping sound transmission and allow air-flow to pass through, and is the important measures eliminating air power noise.The device of the reduction noise on the air-flow path that baffler is mounted in air powered equipment (equipment as larger in relief opening noises such as blower, air compressor, boiler exhaust mouth, generator, water pumps) or in inlet and exhaust system.
At present, known muffler structure is for expanding cavity configuration, noise reduction and damping is carried out by multi-cavity expansion damping convection cell (gas or liquid), need just can complete noise reduction and damping effect through multistage expansion circulation, working efficiency is low, silencer volume and profile are comparatively large simultaneously, are unwell to less installing space.
The audio frequency wavelength of low and medium frequency is longer, is difficult to accomplish complete noise reduction when noise reduction.
model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide the diaphragm type casing baffler of a kind of reasonable in design, easy to operate, noise reduction and good damping effect.
A kind of diaphragm type casing baffler of the present utility model, it comprises casing, odd number silencing board, muffler entrance, silencing end, even number silencing board; 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 silencing board is evenly provided with several through hole one; The hypomere of described even number silencing board is evenly provided with several through hole two.
As preferably, described casing is cuboid, ellipsoid or other any shape.
The utility model is the propagation of carrying out filtering sound and even number silencing board blocking-up sound by several through holes one of odd number silencing board, through filtration repeatedly, blocking-up, thus reaches the effect abated the noise.
Baffler of the present utility model is the muffler structure repeatedly filtering blocking-up type at many levels.
During the utility model operation, when fluid (gas or liquid) is by silencing board, convection cell carries out noise reduction and damping, and in casing, the quantity of silencing board can be determined according to the requirement of noise reduction, and the quantity of silencing board is more, and the efficiency of noise reduction and damping is higher.
The beneficial effects of the utility model: its reasonable in design, easy to operate, volume and profile less, and noise reduction, good damping effect.
accompanying drawing illustrates:
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of odd number silencing board in the present invention;
Fig. 3 is the schematic diagram of even number silencing board in the present invention;
In figure:
Casing 1, odd number silencing board 2, muffler entrance 3, silencing end 4, even number silencing board 5, through hole 1, through hole 27.
embodiment:
As shown in Figure 1 to Figure 3, this embodiment by the following technical solutions: it comprises casing 1, odd number silencing board 2, muffler entrance 3, silencing end 4, even number silencing board 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 silencing board 2 is evenly provided with several through hole 1; The hypomere of described even number silencing board 5 is evenly provided with several through hole 27.
As preferably, described casing 1 is cuboid, ellipsoid or other any shape.
This embodiment is undertaken filtering the propagation that sound and even number silencing board 5 block sound by several through holes 1 of odd number silencing board 2, through filtration repeatedly, blocking-up, thus reaches the effect abated the noise.
The baffler of this embodiment is the muffler structure repeatedly filtering blocking-up type at many levels.
During the operation of this embodiment, when fluid (gas or liquid) is by silencing board 2, convection cell carries out noise reduction and damping, and in casing 1, the quantity of silencing board 2 can be determined according to the requirement of noise reduction, the quantity of silencing board 2 is more, and the efficiency of noise reduction and damping is higher.
This embodiment reasonable in design, easy to operate, volume and profile less, and noise reduction, good damping effect.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
