Abstract
The invention provides a fan silencer, comprising a hollow shell with openings at the two ends, wherein the inner wall of the shell is connected with a circle of barrel-shaped filter screen; a sound absorbing layer is filled between the barrel-shaped filter screen and the shell; flange connecting pieces are arranged at openings of the two end parts of the shell; and the sound absorbing layer is made of superfine glass fiber. The fan silencer consists of the shell, the filter screen, the sound absorbing layer and the flange connecting piece. The sound absorbing layer is made of superfine glass fiber, so that the silencer has the advantages of simple structure, good silencing effect and loss pressure loss.
Description
Technical field
The present invention relates to baffler, relate in particular to a kind of baffler that is applicable to big flow blower fan.
Background technique
At present, high pressure positive blower has obtained widespread usage, but under the higher environment of some air-conditioning requirements, the user also can select the bigger blower fan of use traffic.The noise of the blower fan that flow is bigger also increases relatively, therefore can not satisfy environmental requirement, becomes the more insoluble problem of present inside plants.Baffler is to stop sound transmission and a kind of device that air-flow is normally passed through, and using baffler is the important measures of eliminating noise in the air.Baffler generally is installed in the vent systems of equipment such as blower fan, plays the effect that reduces noise.Existing blower fan baffler has advantage in light weight, that volume is little, though can remove the noise of low frequency, for the relatively large big discharge value blower fan of noise, noise reduction is not clearly, can not satisfy the environmental requirement in the enterprise production.
Summary of the invention
To having the problem that the blower fan baffler is difficult to realize big discharge value blower fan noise reduction now, the claimant improves through research, and another kind of blower fan baffler is provided, and adopts ultra-fine fibre glass as sound-absorbing material, increases substantially the anti-acoustic capability of blower fan baffler.
Technological scheme of the present invention is following:
The present invention provides a kind of blower fan baffler, comprises the housing of hollow and two end part opening, and the inwall of said housing is connected with a circle tubular screen pack, is filled with absorbent treatment between said tubular screen pack and the housing.
Its further technological scheme is: the opening at said housing two end part is equipped with the flange connecting sheet.
And its further technological scheme is: the material of said absorbent treatment is a ultra-fine fibre glass.
Useful technique effect of the present invention is:
The present invention forms the blower fan baffler by housing, screen pack, absorbent treatment, flange connecting sheet.Sound-absorbing material adopts ultra-fine fibre glass, make the simple in structure of baffler, and it is effective to eliminate the noise, and the pressure loss is little.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is that the A of Fig. 1 is to partial enlarged drawing.
Embodiment
For enabling further to understand characteristic of the present invention and technology contents, see also following about detailed description of the present invention and accompanying drawing, yet accompanying drawing only provide reference and the explanation usefulness, be not to be used for the present invention is limited.
As shown in Figure 1, blower fan baffler of the present invention includes housing 1, and housing 1 is a hollow-core construction, the two end part opening, and body shape is cylindrical body or tetragonal body.The inwall of housing 1 has the screen pack 2 of tubular, is evenly distributed with circular filter opening (see figure 2) on the screen pack 2.As shown in Figure 1, be filled with absorbent treatment 3 between the inwall of screen pack 2 and housing 1.Absorbent treatment 3 adopts ultra-fine fibre glass in the present embodiment, utilizes acoustic resistance to eliminate the noise, and sound wave makes the air vibration in the ultra-fine fibre glass, thereby a part of acoustic energy just is converted into heat energy.Because ultra-fine fibre glass physique is light, thermal conductivity is low, thermal insulation and sound absorbing capabilities is good, heat-resisting, antidetonation and have good chemical stability; Be a kind of lightweight, efficient, economic industrial materials; Thereby make the simple in structure of whole device, and it is effective to eliminate the noise, and the pressure loss is little.As shown in Figure 1, the opening at housing 1 two end part also is respectively equipped with flange connecting sheet 4, is used to connect the vent systems of Fan Equipment, as the import and export (air flow is shown in arrow among Fig. 1) of air.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
Claims (3)
1. blower fan baffler; It is characterized in that: the housing (1) that comprises hollow and two end part opening; The inwall of said housing (1) is connected with a circle tubular screen pack (2), is filled with absorbent treatment (3) between said tubular screen pack (2) and the housing (1).
2. according to the said blower fan baffler of claim 1, it is characterized in that: the opening at said housing (1) two end part is equipped with flange connecting sheet (4).
