Detailed description of the invention
In view of anechoic sheet of the prior art many by perforated metal panel as facing material, inner filled glass fiber.Although which can play the effect reducing pneumatic noise, still there is the problem that glass fibre is revealed, cleaning is required that high occasion is inapplicable and it is large to have quality, the drawbacks such as difficulty are installed.
This patent based on this, designed Novel silencing sheet.This anechoic sheet structural framing is made up of three parts: one, chassis body its form for Metal Material Welding; Two, being the fair water cone of chassis body one end, is arcuate structure, and arcuate structure adopts metallic plate to process; Three, be the wedge structure of the chassis body other end, whole framework adopts and is processed by metal structure, has enough intensity, compares metal piercing plate structure anechoic sheet and has quality gently, the feature that intensity is good.Secondly, fair water cone and wedge structure all play the effect of water conservancy diversion, and reduction windage, greatly reduces windage and wind is made an uproar, and is applicable to the requirement of the environment such as ventilating system completely.Again, the present invention is the foaming compressing sound-absorbing material of secondary or other foaming sound-absorbing material at the sound-absorbing material that lower portion is filled, the type sound-absorbing material is without fibrous material, can according to the direct excision forming of the shape size of anechoic sheet, the fibre leakage avoiding fiber absorbing material affects the problem of clean environment.Visible, anechoic sheet of the present invention can meet the demand of ventilating system noise reduction, and there is not the problem of fiber leakage, is more suitable for the place that purity requirements is higher.In addition, it is light that this anechoic sheet compares conventional metals perforated plate anechoic sheet quality, installs and more use manpower and material resources sparingly.
In order to explaination the present invention clearly, be further elaborated below in conjunction with accompanying drawing.
Please refer to Fig. 1, it is depicted as the structural representation of the anechoic sheet that one embodiment of the invention provides.
This anechoic sheet 100, it comprises: chassis body 111, for filling sucting sound material 120; Water conservancy diversion point 112, is arranged at one end of described chassis body 111; Fair water cone 113, is arranged at the other end of described chassis body 111.Whole framework adopts and is processed by metal structure, ensures that general frame intensity is high, indeformable.
When mounted first by chassis body 111 partial fixing good for central filler, and then by modes such as welding or bolts, fair water cone 113 is installed at the upstream extremity of chassis body 111 successively according to flow direction, the water conservancy diversion point 112 of wedge structure is installed in the lower end of chassis body 111 by modes such as welding or bolts, quick and easy for installation.
In embodiments of the present invention, described sound-absorbing material 120 is foaming sound-absorbing material, is good with the compressing sound-absorbing material of the secondary that foams.This sound-absorbing material is without fiber absorbing material, can according to the direct excision forming of the size of anechoic sheet, and the fibre leakage avoiding fibrous sound-absorbing material affects the problem of clean environment, is applicable to the place that purity requirements is higher.The filling mode of traditional fibrous sound-absorbing material often causes filling out-of-flatness, causes anechoic sheet surface to produce bulge.And sound-absorbing material used herein is an excision forming, can cut according to the size of anechoic sheet completely, so the phenomenon of supersaturation filling and bulge can not be produced when installing.
In embodiments of the present invention, glass fiber layer of cloth (not shown) is coated on outside described sound-absorbing material 120.This way can reduce the accumulation of sound-absorbing material surface dirt on the one hand, can strengthen the smoothness on anechoic sheet surface on the other hand, reduces air drag.
In embodiments of the present invention, for needing to need further the anechoic sheet strengthening structural strength, layer of metal stratum reticulare can be welded or there is the metallic sieve of similar structures outside anechoic sheet.Metal net layer (not shown) is coated on outside described chassis body 111, water conservancy diversion point 112, fair water cone 113.
Refer to Fig. 3, in embodiments of the present invention, described water conservancy diversion point 112 is wedge structure, plays the effect of water conservancy diversion, reduces windage, make anechoic sheet be applicable to the environment such as ventilating system.
In embodiments of the present invention, described water conservancy diversion point 112 processes for perforated metal panel, can ensure that gas flow smooth is excessive, reduce the turbulivity of air-flow, thus prevent the generation of pneumatic noise.
Refer to Fig. 4, in embodiments of the present invention, described fair water cone 113 is arcuate structure, plays the effect of water conservancy diversion and reduction windage.
Refer to Fig. 5, in embodiments of the present invention, when applying in the ventilating system of different structure form, such as turn round or the ventilation shaft of other structure type, the anechoic sheet that the present embodiment proposes is irregular plate muffler 200, and described framework is the special-shaped framework main body 211 of irregular structure, as the framework of S shape, thus, anechoic sheet just can be made to be arranged on smoothly in the ventilation shaft of isomery, to achieve better soundproof effect.Specifically, incorporated by reference to see Fig. 6, in order to realize irregular plate muffler, only need special-shaped framework main body 211 to be assembled into and adapt to the irregularly shaped of isomery ventilation shaft, as S shape etc., and water conservancy diversion point 212 and fair water cone 213 are directly assembled in special-shaped framework main body 211, installation regulates fast very convenient, has greatly expanded the suitable environment of anechoic sheet.
In sum, the anechoic sheet that the embodiment of the present invention provides has following beneficial effect relative to prior art:
Described anechoic sheet can not only meet the demand of ventilating system noise reduction, and avoids the fiber leakage problem of sound-absorbing material, can be applicable to the place that purity requirements is higher.In addition, it is light that this anechoic sheet compares conventional metals perforated plate anechoic sheet quality, regulates easy for installation, more use manpower and material resources sparingly.
Although the present invention discloses as above with preferred embodiment; so itself and be not used to limit the present invention; have in any art and usually know the knowledgeable; without departing from the spirit and scope of the present invention; when being used for a variety of modifications and variations, therefore protection scope of the present invention is when being as the criterion depending on those as defined in claim.
