3.
The beneficial effects of the utility model are: relative to prior art, the utility model adopts the acoustical cotton combination of different densities to form " sandwich " formula silencer, be applied to the casing tank wall of low noise electric station, form the denoising structure better intercepting and absorb noise, the requirement that power station is quiet can be met.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of low noise casing tank wall noise reduction composite structure, comprise casing and tank wall thereof, wall sides is provided with the silencer for noise reduction, described silencer is made up of corrugated sheet, acoustical cotton and orifice plate, is disposed with corrugated sheet and acoustical cotton between casing tank wall and orifice plate.
In the present embodiment, described casing is made up of upper box 14 and lower box 15, and the wall sides of upper box 14 is provided with corrugated sheet 1, acoustical cotton II 2, acoustical cotton III 12 and metal perforated plate 13 successively.The wall sides of described lower box 15 is provided with corrugated sheet 8, acoustical cotton I 6, acoustical cotton II 7, acoustical cotton III 9 and metal perforated plate 10 successively.Be connected with bolt 5 by fixing ear 4 and fix between described upper box 14 and lower box 15.
In the present embodiment, between described upper box 14 and lower box 15, be provided with damping seal pad 3.Manger board 11 is also provided with between the metal perforated plate 10 of lower box 15 and damping seal pad 3.Metal perforated plate described in the present embodiment is galvanized steel plain sheet, and the thickness of described acoustical cotton is 30-50mm, and proportion is 20-30 ㎏/m
3.
The utility model adopts perforated plate, acoustical cotton and corrugated steel plate to form " sandwich " formula noise-reducing structure, perforated plate and acoustical cotton are mainly used to eliminate mixed noise, reduce acoustic density and reflected intensity in the casing of power station, steel plate is mainly used in intercepting noise propagation outwardly.The utility model acoustical cotton adopts double-deck or three stackedly adds usage mode, can absorb the acoustic energy of different frequency, thus can meet the quiet requirement in power station.
