Abstract
The invention relates to a blower acoustic shield. The blower acoustic shield comprises an acoustic shield body and is characterized in that a blower is arranged on the bottom of the acoustic shield body and comprises a motor, an air inlet and an air outlet, wherein the air outlet is formed in the bottom of the blower, a plurality of sound insulation plates are arranged between the upside of the blower in the acoustic shield body and the top of the acoustic shield body, induced air ports are formed on the sound insulation plates and are formed in the adjacent sound insulation plate in a staggering manner, the induced air port in the bottommost sound insulation plate is positioned in a motor side, the induced air hole is also formed in the top of the acoustic shield body, an air inlet regulating device is also arranged on the induced air hole in the acoustic shield body, and the acoustic shield body comprises an acoustic shield outer layer and an acoustic shield inner layer. The blower acoustic shield has the advantages that the blower acoustic shield is convenient to install, parts which generate higher noise are enclosed through the acoustic shield, so that the noise can be effectively controlled to be transferred to the outside, influences of the noise to the periphery are reduced, noise control is realized, and environmental-friendly requirements are satisfied.
Description
Technical field
The present invention relates to the noise management technique field, relate in particular to a kind of air blower acoustic hood.
Background technique
The noise pollution point multiaspect of blower and wide, prior art often only install wind inlet silencing device additional in the blower air sucking mouth when solving this class voice, disc type is arranged, and cartridge type is also arranged, but soundproof effect is very undesirable.Its reason is that the noise of blower not only is the intake grill place, derives from simultaneously greatly the power motor of blower casing and blower.Moreover, install silencing apparatus additional at its intake grill, have because the silencing apparatus resistance is excessive, make electromotor overload and shut down, had a strong impact on its functional reliability.The fan noise of prior art is processed, and does not have a kind of good small-sized fermented soya beans, salted or other wise fan noise basic handling scheme of landing the export-oriented indoor air-supply of wall, and the noise processed ability is inadequate.Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this invention is to provide a kind of air blower acoustic hood.
The technical solution used in the present invention is:
A kind of air blower acoustic hood, comprise the acoustic hood cover body, described acoustic hood cover body bottom is provided with blower, described blower comprises motor, intake grill and exhaust outlet, described motor is located at blower one side, described intake grill is located at the blower opposite side, described exhaust outlet is located at blower bottom, be provided with some sound insulationg boards between the inner blower upside of described acoustic hood cover body and the acoustic hood cover body top, described sound insulationg board is provided with air-vent, described air-vent is crisscross arranged at adjacent sound insulationg board, voidlessness between the sound insulationg board of described bottommost and the blower.
Air-vent on the sound insulationg board of described bottommost is positioned at motor side.
Described acoustic hood cover body also is provided with air-vent on the top, and the position opposite of air-vent on described air-vent position and the downside sound insulationg board also is provided with the air port controlling device on the air-vent on the described acoustic hood cover body.
Described acoustic hood cover body comprises the outer and acoustic hood internal layer of acoustic hood, and described sound insulationg board, acoustic hood internal layer and acoustic hood skin are made by the sound insulation material.
Advantage of the present invention is: easy for installation, the parts larger noise are closed with acoustic hood, effectively control the unofficial biography of noise, and noise reduction is realized noise abatement, meet the requirement of environmental protection to impact on every side.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Wherein: 1, acoustic hood cover body, 2, acoustic hood is outer, 3, the acoustic hood internal layer, 4, blower, 5, motor, 6, intake grill, 7, exhaust outlet, 8, sound insulationg board, 9, air-vent, 10, the air port controlling device.
Embodiment
As shown in Figure 1, a kind of air blower acoustic hood of the present invention, comprise acoustic hood cover body 1, described acoustic hood cover body 1 bottom is provided with blower 4, described blower 4 comprises motor 5, intake grill 6 and exhaust outlet 7, described motor 5 is located at blower 4 one sides, described intake grill 6 is located at blower 4 opposite sides, described exhaust outlet 7 is located at blower 4 bottoms, be provided with three sound insulationg boards 8 between described acoustic hood cover body 1 inner blower 4 upsides and acoustic hood cover body 1 top, described sound insulationg board 8 is provided with air-vent 9, described air-vent 9 is crisscross arranged at adjacent sound insulationg board 8, voidlessness between the sound insulationg board 8 of described bottommost and the blower 4, air-vent 9 on the sound insulationg board 8 of described bottommost is positioned at motor 5 sides, described acoustic hood cover body also is provided with air-vent 9 on 1 top, the position opposite of air-vent 9 on described air-vent 9 positions and the downside sound insulationg board 8, also be provided with air port controlling device 10 on the air-vent 9 on the described acoustic hood cover body 1, described acoustic hood cover body 1 comprises acoustic hood outer 2 and acoustic hood internal layer 3, described sound insulationg board 8, acoustic hood internal layer 3 and acoustic hood skin 2 are made by the sound insulation material, easy for installation, the parts larger noise are closed with acoustic hood, effectively control the unofficial biography of noise, noise reduction is on impact on every side, realize noise abatement, meet the requirement of environmental protection.
