Abstract
The utility model discloses a wall body with noise elimination and ventilation functions, which comprises an inner wall body, an outer wall body, an air inlet, an air outlet and a ventilation duct, wherein the inner wall of the ventilation duct is provided with a plurality of sound absorption baffle plates to form a plurality of communicated resonance noise elimination cavities, the noise elimination material is favorable for eliminating low-frequency noise by the resonance noise elimination cavities and the resonance noise elimination principle. If supplemented by the noise elimination structure of the inner wall, the wall body with noise elimination and ventilation functions has more remarkable noise reduction effect.
Description
Technical field
The utility model relates to a kind of construction wall, relates in particular to have the body of wall of noise elimination, ventilation function.
Background technology
The machine room and the sound insulation enclosure that are used for various noise abatement at present, particularly various petroleum gas booster stations, the CNG gas station, engineering machinery, the sound absorption body of wall in equipment wideband noise places such as dynamic power machine, generally be sound absorption material to be installed absorb sound in body of wall, utilize body of wall itself to insulate against sound, when needing heat dissipation ventilation, at ventilation opening silencing apparatus is installed and is carried out noise elimination noise reduction, but at the general frequency broad of noise that above-mentioned place produced, high-frequency noise is not only arranged, also has a large amount of low-frequency noises, the noise reduction of the allocation plan that body of wall sound absorption and silencing apparatus are eliminated the noise in this employing is unsatisfactory, and especially then effect is poorer for absorbing low-frequency noise.If reach the effect of eliminating the noise preferably, must increase silencing apparatus, so not only taken bigger space, and installation also comparatively bothers the cost of investment height.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can ventilate, can eliminate well again the body of wall of high-frequency noise and low-frequency noise, this body of wall sound absorption frequency range broad, and noise reduction is obvious.
The purpose of this utility model is achieved in that
A kind of ventilation noise elimination body of wall comprises interior body of wall, outer body of wall, air intake, air outlet and ventilation stack, and wherein the inwall of ventilation stack is provided with some sound-absorbing partitions and forms the resonant silencing chamber that several communicate;
In order to eliminate the noise better, further improving is that several resonant silencing chambeies are set to the staggered structure that communicates;
Described sound-absorbing partition is by being made of orifice plate, water proof and dust proof material and sound absorption material successively in outer the reaching.
The utility model has following advantage than prior art:
Because be provided with the resonant silencing chamber that several communicate in the ventilation stack of the utility model in body of wall, utilize the resonant silencing principle to eliminate the noise, this noise elimination structure helps eliminating low-frequency noise; Simultaneously, on sound-absorbing partition, adopt by the solid sound absorption construction that constitutes by orifice plate, water proof and dust proof material and sound absorption material successively in reaching outward, also comparatively remarkable for the elimination of high-frequency noise; If be aided with the sound absorption construction of interior wall, noise reduction is more obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the sectional drawing of the utility model sound-absorbing partition.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details; but protection domain of the present utility model has more than and is limited to these examples; such as, to the change of sound-absorbing partition structure or the wherein change of sound absorption material or water proof and dust proof material, all belong to protection domain of the present utility model.
Embodiment: a kind of ventilation noise elimination body of wall, comprise by interior facing material, damping material, sound insulating material, the dustproof and waterproof material, the interior body of wall 1 that skeleton and sound absorption material constitute, by outer facing material, damping material, sound insulating material, the dustproof and waterproof material, the outer body of wall 2 that skeleton and sound absorption material constitute, be positioned at the air intake 3 of outer body of wall 2 upper ends, with air outlet 4 that is positioned at the body of wall lower end and the ventilation stack 5 that is positioned at body of wall, the inwall of its ventilation stack 5 is provided with some sound-absorbing partitions 6, thereby form several staggered resonant silencing chambeies 7 that communicates, the sound-absorbing partition 6 of this setting by outer and in successively by orifice plate 10, water proof and dust proof material 8 and sound absorption material 9 constitute.
Wherein, sound absorption material can be selected sponge well known in the art, glass cotton etc. for use; The water proof and dust proof material can be selected glass cloth well known in the art, film etc. for use.
Claims (3)
1, a kind of ventilation noise elimination body of wall, comprise interior body of wall (1), outer body of wall (2), air intake (3), air outlet (4) and ventilation stack (5), the inwall that it is characterized in that ventilation stack (5) is provided with some sound-absorbing partitions (6) and forms the resonant silencing chamber (7) that several communicate.
