Description
[technical field]
The present invention and aerodynamic noise control field, especially a kind of full microperforated absorber acoustic filter.
[background technology]
In prior art, acoustic filter has application in ventilating system more, has good noise elimination effect for pneumatic noise, and passes
The acoustic filter of system many by perforated metal panel as facing material, the sound-absorbing material such as internal filled glass fiber.Although traditional approach
The effect reducing pneumatic noise can be played, but environment is made by its risk that there is sound-absorbing material inefficacy and sound-absorbing material effusion
The shortcoming becoming secondary pollution.
Therefore, for avoiding above-mentioned technical problem, necessary offer one has structure improved acoustic filter, existing to overcome
There is the described defect in technology.
[summary of the invention]
In order to overcome above-mentioned weak point present in prior art, it is an object of the invention to provide a kind of full micropunch sound absorption
Structure acoustic filter.
In order to reach above-mentioned purpose, the present invention uses following concrete technical scheme: full microperforated absorber acoustic filter,
By the cavity one of internal layer forming closed under internal layer in the left inside layer of micropunch, the right internal layer of micropunch, micropunch and micropunch, described
Multilamellar micropunch anechoic sheet, internal layer and micropunch in the left inside layer of described micropunch, the right internal layer of micropunch, micropunch it is provided with in cavity
Lower internal layer adjacent is fixed by connecting angle iron, internal layer and micro-wear in the left inside layer of described micropunch, the right internal layer of micropunch, micropunch
Under hole, the surface of internal layer is respectively arranged with shell and acoustic filter lower casing on the left outside shell of acoustic filter, acoustic filter right casing, acoustic filter,
The two ends of described cavity are provided with flange.
Further, in the left inside layer of micropunch of the present invention, the right internal layer of micropunch, micropunch under internal layer and micropunch in
Layer all uses hollow structure.
Further, on the left outside shell of acoustic filter of the present invention, acoustic filter right casing, acoustic filter under shell and acoustic filter outside
Shell all uses hollow structure.
Present invention advantage compared with prior art is: the present invention uses the full microperforated absorber of multilamellar to carry out noise reduction,
Compared with the acoustic filter of traditional filling sucting sound material, it is not filled with any sound-absorbing material, the fibre of sound-absorbing material and can be avoided
Dimension leakage problem, it is possible to be applicable to the high place of purity requirements and the place of other particular/special requirement, such as superhigh temperature, ultralow
The noise elimination noise reduction in the places such as warm, high wind pressure and wind speed.It addition, for the soundproof effect improving acoustic filter, according to the size of cavity, can
To increase the multilamellar micropunch anechoic sheet of respective numbers in cavity, divide equally cavity, reach the noise elimination of bigger effect.The present invention ties
Structure advantages of simple, easy for installation, service life is long, can effectively substitute traditional ventilation silencer.

Fig. 1 is the structural representation of the present invention；
Fig. 2 is that the A-A of Fig. 1 is to sectional view；
Fig. 3 is that the B-B of Fig. 1 is to sectional view；
The present invention is described in further detail below in conjunction with the accompanying drawings.
[detailed description of the invention]
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the tool to the present invention below in conjunction with the accompanying drawings
Body embodiment is described in detail.
Elaborate detail in the following description so that fully understanding the present invention.But the present invention can with multiple not
Being same as alternate manner described here to implement, those skilled in the art can do class in the case of intension of the present invention
Like promoting.Therefore the present invention is not limited by following public being embodied as.
Referring to shown in Figure of description 1 to Fig. 3, the present invention is full microperforated absorber acoustic filter, left by micropunch
The cavity 1 of internal layer 4 forming closed, described cavity 5 under internal layer 3 and micropunch in internal layer 1, the right internal layer of micropunch 2, micropunch
Inside it is provided with multilamellar micropunch anechoic sheet 6, internal layer 3 and micropunch in the left inside layer of described micropunch 1, the right internal layer of micropunch 2, micropunch
Lower internal layer 4 adjacent is fixed by connecting angle iron 7, internal layer 3 in the left inside layer of described micropunch 1, the right internal layer of micropunch 2, micropunch
It is respectively arranged with on the left outside shell of acoustic filter 8, acoustic filter right casing 9, acoustic filter shell 10 with the surface of internal layer under micropunch 4 and disappears
Sound device lower casing 11, the two ends of described cavity 5 are provided with flange 12.The present invention uses the full microperforated absorber of multilamellar to drop
Make an uproar, it addition, for the soundproof effect improving acoustic filter, according to the size of cavity, respective numbers can be increased in cavity many
Layer micropunch anechoic sheet, divides equally cavity, reaches the noise elimination of bigger effect.Present configuration advantages of simple, easy for installation, use the longevity
Life is long, can effectively substitute traditional ventilation silencer.
It should be noted that internal layer 3 and micro-in the left inside layer of micropunch of the present invention 1, the right internal layer of micropunch 2, micropunch
The lower internal layer 4 of perforation all uses hollow structure.
Also, it should be noted shell 10 and on the left outside shell of acoustic filter of the present invention 8, acoustic filter right casing 9, acoustic filter
Acoustic filter lower casing 11 all uses hollow structure.
But, above-mentioned detailed description of the invention is exemplary, is to preferably enable those skilled in the art
Understand this patent, it is impossible to be not understood as this patent is included the restriction of scope；As long as the institute according to spirit disclosed in this patent
Any equivalent change made or modification, each fall within the scope that this patent includes.
