Summary of the invention:
In order to overcome the described shortcoming of background technique, the utility model purpose provides a kind of brand-new small-sized Floor Tom blower fan acoustic hood technology, to control sound source for taking along machine, use comprehensive means, can realize satisfying one class mixed zone, city, two class mixed zones, the daytime of high-value district fermented soya beans, salted or other wise blower fan periphery and the noise at night and place restrictions on requirement.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of small-sized Floor Tom blower fan acoustic hood, form by acoustic hood inner core (1), acoustic hood skin (2), acoustic hood internal layer (3), acoustic hood cover plate (4); It is characterized in that: acoustic hood skin (2) is attached at acoustic hood inner core (1) outer surface, and acoustic hood internal layer (3) is attached at acoustic hood inner core (1) internal surface, and acoustic hood cover plate (4) is covered on the whole small-sized Floor Tom blower fan acoustic hood.
Described acoustic hood inner core (1) is to make with upper steel plate by 1.4 millimeters, and is no less than two air intake baffle plates (K) at air intake, and the width that keeps out the wind (A2) of air intake baffle plate (K) for (0.6～0.8) of the intake grill wide (A1) of whole acoustic hood inner core (1) (A1); Adjacent air intake baffle plate (K) is staggered.
Described acoustic hood internal layer (3) is to be made by sound-absorbing or sound insulating sheet material, and contains electronic fermented soya beans, salted or other wise blower fan (5).
Described acoustic hood skin (2) is to be made by sound insulating sheet material.
Described acoustic hood cover plate (4) inner core material is with acoustic hood inner core (1) material, and lower floor's cladding material is identical with acoustic hood internal layer (3) material, and the upper strata cladding material is identical with acoustic hood skin (2) material.
Described acoustic hood cover plate (4) downside has seam and acoustic hood internal layer (3) inner periphery to fasten.
The airduct skin of the indoor air-supply of described subtend has sound-absorbing, soundproof material covering.
The beneficial effects of the utility model are: a kind of small-sized Floor Tom blower fan acoustic hood is realized noise abatement with the means of control sound source, reaches environmental requirement.
Description of drawings:
Fig. 1 is that the small-sized Floor Tom blower fan of the utility model acoustic hood is implemented schematic illustration substantially.
Be illustrated as:
The wide A1 of outer 2 acoustic hood internal layer 3 acoustic hood cover plates, the 4 electronic fermented soya beans, salted or other wise blower fan 5 windshield plate K intake grills of the acoustic hood inner core 1 acoustic hood width A2 that keeps out the wind
Embodiment:
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
A kind of small-sized Floor Tom blower fan acoustic hood as shown in Figure 1 is made up of acoustic hood inner core 1, acoustic hood skin 2, acoustic hood internal layer 3, acoustic hood cover plate 4; It is characterized in that: acoustic hood skin 2 is attached at acoustic hood inner core 1 outer surface, and acoustic hood internal layer 3 is attached at acoustic hood inner core 1 internal surface, and contains electronic fermented soya beans, salted or other wise blower fan 5, and acoustic hood cover plate 4 is covered on the whole small-sized Floor Tom blower fan acoustic hood.Described acoustic hood inner core 1 is to make preferably 2.5～3 millimeters with upper steel plate by 1.4 millimeters.Be no less than two air intake baffle plate K at air intake, preferably four, (0.6～0.8) A1 of the wide A1 of intake grill of the whole acoustic hood inner core 1 that the width A2 that keeps out the wind of air intake baffle plate K is; Adjacent air intake baffle plate K is staggered, and necessary air intake is smooth and easy, and flow is enough.Must not there be hole and slit in acoustic hood inner core 1 each bending place, in case leak-stopping sound.Described acoustic hood internal layer 3 is to be made by sound-absorbing or sound insulating sheet material, as fiberboard, cane fiber board, particleboard, mineral wool board or the like.Described acoustic hood skin 2 is to be made by sound insulating sheet material, as plank, particleboard, particleboard oversite concrete or the like.Described acoustic hood cover plate 4 inner cores are with acoustic hood inner core 1 material, lower floor's cladding material is identical with acoustic hood internal layer 3 materials, and the upper strata cladding material is identical with outer 2 materials of acoustic hood, and acoustic hood cover plate 4 downsides have seam, fasten the location with acoustic hood internal layer 3 inner peripherys, can increase and control the function of making an uproar.Airduct to the export-oriented indoor air-supply of wall adopts sound-absorbing, soundproof material wrapping, adds bituminous coating as slag wool, industrial felt, outer cement-lime mortar.Hole between acoustic hood periphery and ground and slit add bituminous coating shutoff leakage sound with cement-lime mortar.
