Abstract
The utility model discloses a high -efficient noise elimination static pressure case, including static pressure case body, the interior side surface of static pressure case body is equipped with the amortization cavity, the inside packing of amortization cavity has the amortization cotton, the upper portion of static pressure case body is equipped with the guide duct, the inside of guide duct is equipped with the amortization tile, the lower part of static pressure case body is equipped with the air current air brake, the surface of air current air brake is equipped with porous noise rubber board. This high -efficient noise elimination static pressure case is equipped with the amortization cavity through the inboard at static pressure case body, and cotton in the inside packing amortization of amortization cavity, and when gas striking static pressure case body, the sound of partial striking can be absorbed to the amortization cotton, gaseous under the effect of air current air brake, the speed of air current reduces, and gaseous with the air current air brake on the contact of porous noise rubber board, partly gaseous sound that produces is absorbed by porous noise rubber board, the partial noise that the amortization tile can absorbing gas produces at static pressure case body can reach good noise cancelling effect.
Description
Technical field
The utility model belongs to noise elimination technique field, is specifically related to a kind of efficient noise elimination plenum chamber.
Background technology
Plenum chamber is that supply air system reduces dynamic pressure, increases the accessory of a kind of necessity of static pressure, steady air flow and minimizing airstream vibration, and it can make air-supply effect more desirable.Air can cause noise through plenum chamber, for the equipment that quiet requirement is higher, must reduce noise.Current plenum chamber is varied, and the quiet measure taked also is varied, but desirable all not to the utmost, and the noise of reduction is limited.A kind of efficient noise elimination plenum chamber is proposed for this reason.
Utility model content
The purpose of this utility model is to provide a kind of efficient noise elimination plenum chamber, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of efficient noise elimination plenum chamber, comprise plenum chamber body, the top of described plenum chamber body is provided with air outlet, the bottom of described plenum chamber body is provided with air inlet, the inner surface of described plenum chamber body is provided with noise reduction cavity, the inside of described noise reduction cavity is filled with silencing cotton, the top of described plenum chamber body is provided with guide duct, the inside of described guide duct is provided with Noise reduction tile, the bottom of described plenum chamber body is provided with flow slowing down plate, the surface of described flow slowing down plate is provided with the reducing noise rubber plate of porous.
Preferably, described flow slowing down plate is set to 2 groups, and often organize 2-4 block, flow slowing down plate is 45
0be arranged in parallel.
Preferably, described guide duct is that interval is equidistantly arranged.
Technique effect of the present utility model and advantage: this efficient noise elimination plenum chamber is by being provided with noise reduction cavity in the inner side of plenum chamber body, and fill silencing cotton in the inside of noise reduction cavity, when air impingement plenum chamber body, silencing cotton can absorption portion clash into sound; Gas is under the effect of flow slowing down plate, and the speed of air-flow reduces, and gas is contacting with the porous reducing noise rubber plate on flow slowing down plate, and the sound that a part of gas produces is absorbed by the reducing noise rubber plate of porous; When last gas is by guide duct, because the inside of guide duct is provided with Noise reduction tile, Noise reduction tile can absorb the partial noise that gas produces at plenum chamber body, by three kinds of common noise reductions of structure, good erasure effect can be reached, solve the incomplete problem of current plenum chamber noise reduction.
