Abstract
The utility model discloses a silencing equipment as a silencing device for a heavy-duty equipment which produces noise. The utility is aimed to cut manufacturing cost, simplify structure, and improve the effect of silencing. The utility model includes a shell 1 with a pair of buckle 2 arranged therein. The buckle 2 is provided with a group of fixing holes 3. Each of the fixing holes 3 is provided with a hush pipe 5 with micro pores 4 formed on. The clearances between all the hush pipes 5 are filled with non-metallic acoustic absorbing material 5. The device is used for the abatement of huge fluidal noise, in particular for the abatement of work noise produced by heavy-duty equipment such as an aero engine testing stand, and a wind tunnel trial stand.
Description
Technical field: the utility model relates to a kind of quieter of large-scale audible device.
Background technology: when main equipments such as aeromotor testing table, wind tunnel test platform were worked, the pollution of noise was very serious, must effectively handle, existing device structure complexity, and the cost height, fluid resistance is big, and effect is bad.
Summary of the invention:
The technical problems to be solved in the utility model: the muffling device that a kind of low cost of manufacture, simple in structure and good muffling effect are provided.
The technical scheme that addresses the above problem:
Muffling device, its composition comprises: shell, a pair of buckle is housed in the described shell, have one group of fixed orifice on the described buckle, the micropore hush pipe is housed in the described fixed orifice, be filled with nonmetal acoustical material between the described hush pipe.
Have flange around the above-mentioned muffling device, the fixed orifice of described buckle, this flange outside closely cooperates with described hush pipe, in the import and export of described shell connecting flange is housed.
Above-mentioned muffling device is equipped with on the described fixed orifice and draws cap, and described cap and the hush pipe bonding of drawing fixed, and between the described buckle bar that is fixedly connected is housed.
Above-mentioned muffling device, described acoustical material are glass silk flosssilk wadding and/or rock wool and/or alumina silicate and/or foamed plastic.
Beneficial effect compared with prior art:
1. the fluid that contains noise enters into numerous hush tubes through the fixed orifice of buckle, and the micropore by the One's name is legion above the hush tube is distributed to it to contain in the very microporous nonmetal deadener and goes, and by three grades of dispersions, makes that noise is most of to be eliminated.
2. have flange around the fixed orifice of buckle, make hush tube be enclosed within its outside, can obviously lower the resistance of fluid like this, avoid the impact of the excessive noise fluid of intensity, avoid producing new noise, strengthen the effect that subtracts back noise.
3. in the import and export of shell connecting flange is housed, uses in groups after this product can be connected easily, adapt to reducing noise needs such as aeromotor testing table, wind tunnel test platform.
4. dress draws cap on a part of fixed orifice, and this draws cap and described hush tube bonding to fix, and can make draw bail more stable, more reliable like this.If the bar that is fixedly connected is housed between the described buckle again, will make structure more stable.
By enter hush tube, enter micropore and enter three grades of acoustic absorbant shuntings and disperse, comprise adopt nonmetallic sound-absorbing porous material after, to repeatedly the circling round of sound wave, its intensity is obviously reduced by its micropore space.
6. simple in structure, cost is low, can significantly reduce noise.
Description of drawings: accompanying drawing 1 is the structural representation of this product.Accompanying drawing 2 is vertical views of accompanying drawing 1.
Accompanying drawing 3 is to install the structural representation that draws cap on fixed orifice additional.
Below in conjunction with the concrete embodiment of description of drawings:
Embodiment 1:
Muffling device, its composition comprises: shell 1, a pair of buckle 2 is housed in the described shell 1, and have one group of fixed orifice 3 on the described buckle 2, band micropore hush pipe 5 is housed in the described fixed orifice 3, is filled with nonmetal acoustical material 4 in the ligament between the described hush pipe 5.
Embodiment 2:
Embodiment 1 described muffling device has flange 6 around the fixed orifice 3 of described buckle 2, and the outside of this flange 6 and described hush pipe 5 internal diameters closely cooperate, and in the import of described shell 1 and the outlet connecting flange 7 is housed.
Embodiment 3:
The described muffling device of the foregoing description, be equipped with on the described fixed orifice 3 and draw cap 8, the described cap 8 that draws is fixing with hush pipe 5 bondings, between the described buckle 2 bar 9 that is fixedly connected is housed, the position between two buckles 2 is not changed because of the influence of noise and vibrations by the bar 9 that is fixedly connected.
Embodiment 4:
The described muffling device of the foregoing description, described acoustical material is a kind of or its potpourri in glass silk flosssilk wadding and/or rock wool and/or alumina silicate and/or the foamed plastic, by these filametntary a large amount of holes that stop and wherein comprise, the intensity of making an uproar living is reduced.
Claims (4)
