Abstract
The utility model relates to an air pipe structure of making an uproar falls in light. The utility model discloses an air pipe structure of making an uproar falls in light appearance is the rectangle, the subassembly including: there are low noise axial fan, piece formula muffler, organic glass steel access hole, organic glass steel wind channel, the rain -proof cap of organic glass steel, installing support etc. The utility model discloses simple structure, technical maturity, convenient to use, low in cost, the suitable popularization.
Description
Technical field
This utility model relates to a kind of light noise-reducing ventilation duct structure.
Background technology
Along with noise hazard understanding is goed deep into by people, whether between enterprise and employee, or the dispute caused because of noise between enterprise and sensitive spot resident is all to rise year by year；Meanwhile, the most industrial Factory Building or civil buildings ventilate is all essential.Traditional industry Factory Building and civil buildings ventilate and are substantially brick and mix air channel and add the structure of blower fan, this structure otherwise expensive, otherwise noise reduction is undesirable.
This utility model light noise-reducing ventilation duct structure profile is rectangular.
Summary of the invention
For the problems referred to above, the purpose of this utility model be to provide can noise reduction, can ventilate, light weight, repair and maintenance easily one light noise-reducing ventilation duct structure.
For achieving the above object, first, light noise-reducing ventilation duct structure profile is rectangular, uses low noise axial fan, chip deafener, perspex steel access hole, perspex steel air channel, the version of perspex steel rainhat.Secondly, this utility model is also provided with mounting bracket and low noise axial fan, chip deafener, perspex steel air channel, perspex steel rainhat is fixed, to reach noise reduction, ventilation, light weight, the convenient effect of repair and maintenance.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Such as figure
1
Shown in: a kind of light noise-reducing ventilation duct structure mainly has low noise axial fan, chip deafener, perspex steel air channel, perspex steel rainhat, mounting bracket etc..Wherein low noise axial fan, chip deafener use angle bar frame to install and fix, and use Flange joint, perspex steel rainhat to use lightweight angle steel to be fixed on perspex steel air channel between perspex steel air channel.
During the work of light noise-reducing ventilation duct structure, open low noise axial fan.First, low noise axial fan is forced the heat in building is drawn out to tunnel inlet.Heat transmits in the way of air-flow outward, and meanwhile, air-flow is by low noise axial fan forcibly changing direction, and a part of acoustic energy is weakened；When the air-flow after weakening arrives chip deafener, most acoustic energy is weakened the most weakened, is entered by the air-flow after chip deafener
20mm
The glass fibre reinforced plastic air channel with good soundproof effect, glass fibre reinforced plastic air channel glass outer steel is thick
6mm
, after inner layer glass steel
2mm
, middle folder
12mm
Aluminium silicate wool.Finally, broadcast to air channel unofficial biography by the interval between rainhat and glass fibre reinforced plastic air channel after air-flow.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; on the premise of without departing from this utility model structure; some deformation and improvement can also be made; also should be considered as protection domain of the present utility model, these are all without affecting effect and the practical applicability that this utility model is implemented.
Claims (1)
1. a light noise-reducing ventilation duct structure, this construction profile is rectangular, it is characterized in that: this structure is made up of low noise axial fan, chip deafener, perspex steel air channel, perspex steel rainhat, mounting bracket, this structure is the use of the perspex steel air channel with good soundproof effect that thickness is 20mm, perspex steel air channel glass outer steel thickness 6mm, 2mm after inner layer glass steel, middle folder 12mm glass cotton.
