Abstract
The utility model discloses a silencing static pressure box, which consists of a shell, and an upper flange and a left flange on the shell, and is characterized in that: the shell is made of materials with three structures, namely glass cloth on the innermost layer, glass cotton on the intermediate layer and a galvanized sheet on the outermost layer; and vibration noise produced by an air flow of the static pressure box can be effectively obstructed by the shell. Perforated plates are uniformly and densely arranged in the shell and can be used for keeping stable and equilibrium ventilation volume of the static pressure box; and the upper flange and the left flange contribute to fixing the silencing static pressure box. The silencing static pressure box has the advantages of effectively reducing noise of the static pressure box and achieving a better air supply effect of a fan, along with novel design, simple structure and silencing and static pressure effects.
Description
Technical field:
The utility model relates to a kind of noise elimination static pressure box.
Background technique:
In the blower fan supply air system static pressure box is housed, static pressure box generally is located at blower fan and air-conditioning box place more, can reduce dynamic pressure, increase static pressure, steady air flow and minimizing airstream vibration, makes the air-supply effect desirable more.Shortcomings such as existing static pressure box mostly is single exhaust outlet, casing does not have problems such as airduct that soundproof material is connected with blower fan is relatively shorter, causes the static pressure box noise big, and air output is little, air quantity is unstable, and the airstream vibration noise is big.
The model utility content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of noise elimination static pressure box is provided, and can keep the ventilation stable equilibrium of static pressure box, and can greatly reduce the noise of airstream vibration.
In order to achieve the above object, the technical solution of the utility model is as follows: the noise elimination static pressure box, form by upper flange on housing, the housing and left flange, it is characterized in that described housing is made up of the material of three kinds of structures, the glass cloth of innermost layer, the glass wool in mesosphere and outermost galvanized sheet, housing can effectively intercept the vibrating noise of the air-flow generation of static pressure box.Evenly densely arranged perforated plate is arranged in the described housing, and described perforated plate can keep the ventilation stable equilibrium of static pressure box.Described upper flange and left flange help the fixing of static pressure box of eliminating the noise.
Beneficial effect: the utility model modern design, simple in structure, the effect of noise elimination static pressure is arranged, can effectively reduce the noise of static pressure box, make the air-supply effect of blower fan better.
Description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is 1 a structural representation among Fig. 1.
Among the figure: 1, housing, 2, glass cloth, 3, glass wool, 4, galvanized sheet, 5, upper flange, 6, left flange, 7, perforated plate.
Embodiment:
Embodiment: as depicted in figs. 1 and 2, the noise elimination static pressure box, form by upper flange 5 on housing 1, the housing 1 and left flange 6, the housing of described housing 1 comprises three kinds of structures, the glass cloth 2 of innermost layer, the glass wool 3 in mesosphere and outermost galvanized sheet 4, described housing 1 has good soundproof effect.Be perforated plate 7 in the described housing 1,7 one-tenth dense arrangement of perforated plate, the wind that can allow blower fan produce evenly flows out, and reduces the noise of air friction, and hydrostatic pressure is arranged.
Beneficial effect: the utility model modern design, simple in structure, the effect of noise elimination static pressure is arranged, can effectively reduce the noise of plenum chamber, make the air-supply effect of blower fan better.
