Description
Technical field
The present invention relates to a kind of silencer, especially a kind of ventilation silencer that is installed in body of wall connection indoor and outdoor.
Background technology
Progress along with society, rapid economy development, industrial premises stands in great numbers, and the noise in the industrial premises has a strong impact on people's work, studying and living, for reducing noise, reduce noise pollution, big number all adopts silencer to reduce noise, and present silencer all is cylindric or column shape mostly, noise elimination structure is simple, specific aim to low frequency noise and high frequency noise is not strong, and the noise elimination weak effect can not satisfy people's demand.
Summary of the invention
The objective of the invention is to develop a kind of addressing the above problem, simple in structure, volume is little, the ventilation silencer of sound absorption frequency bandwidth.
The present invention is achieved through the following technical solutions:
The present invention is mainly by framework; the high frequency anechoic sheet; the low frequency anechoic sheet; air exhauster; ventilating blind and airstrainer are formed; it is characterized in that: the high frequency anechoic sheet; low frequency anechoic sheet and air exhauster are arranged in the framework inner chamber; ventilating blind is arranged on the horizontal opening end of framework; airstrainer is arranged on the vertical opening end of framework; wherein; framework mainly comprises box body and cover plate; cover plate is arranged on box surface; the protection box body; framework is " 7 " font; the inner cavity that forms; cover plate one side forms air exhauster door is installed; air exhauster is provided with air exhauster the door position is installed, and the high frequency anechoic sheet is arranged in the horizontal cavity of cavity, and the low frequency anechoic sheet is arranged in the vertical inner chamber of cavity.
When practical application, framework is made by the metallic plate that satisfies noise demand for control thickness, at framework built-in sound-absorbing material, guarantee the dual needs that insulate against sound and absorb sound, lid surface is done zinc-plated and the dual preservative treatment of workmanship of spraying plastics, the high frequency anechoic sheet utilizes acoustics professional knowledge that different-thickness is set with the noise frequency that the low frequency anechoic sheet sends according to sound source targetedly with noise control target and selects for use different sound-absorbing materials to constitute, specifically be meant the wavelength of calculating the noise of the frequency band that is primarily aimed at according to the aerial spread speed of sound and frequency meter, determine the high frequency anechoic sheet according to wavelength characteristic, the thickness of low frequency anechoic sheet and selection are fit to the high material of this frequency band acoustic absorptivity, selected material comprises centrifugally glass-wool, silicate aluminum board and fiber sound absorption plate etc., air exhauster is selected low noise, the energy-conserving and environment-protective blower fan of low-power consumption, the ventilating blind material is an aluminium alloy, purpose is guarantee indoor decorative effect beautiful and comfortable, airstrainer guarantees the cleaning of room air, it is indoor to prevent that simultaneously insect etc. from entering the room by silencer, when mounted, can be fixed on the body of wall and can use by hammer into expansion bolt at body of wall, reach purpose of design.
The present invention has following advantage:
1, via enforcement of the present invention, adopt high frequency anechoic sheet and low frequency anechoic sheet, be fit to various noise sources, sound deadening capacity can satisfy different needs with the length of holder adjustment anechoic sheet, and sound deadening capacity is big, and frequency of noise elimination is wide.
2, via enforcement of the present invention, directly air exhauster is placed in the silencer, not only attractive in appearance beautiful but install convenient.
3, via enforcement of the present invention, simple in structure, be easy to processing and fabricating, cost is low, makes things convenient for extensive use, and sound deadening capacity is big.
