Description
Technical field
The utility model air draft noise elimination passage belongs to air draft noise elimination technique field.
Background technology
In the large industrial enterprise, ore in the hole, the ore deposit transhipment transmission system visual plant that is absolutely necessary.Usually, the noise of ore transhipment transmission system is all bigger, generally all surpasses 95dBA, and with stronger vibration.For requirements of one's work; the worker's of control and operation ore transhipment transmission system rest area; distance apart from transhipment transmission system itself is all very near; the noise of equipment and vibration cause serious harm to workers health; so strengthen noise control, improve to the healthy protection of the worker of the enterprise measure that is very important to industrial and mining enterprises' transhipment transmission system.
In the existing technology, mainly be that enclosing is carried out in the rest area, and take suitable sound insulation and vibration isolation to handle for the measure of the healthy protection of the worker of enterprise.The rest area will maintain the circulation of air, and existing exhaust system can't well be eliminated noise.
The utility model content
The utility model overcomes the deficiencies in the prior art, and technical problem to be solved is for providing a kind of air draft noise elimination passage of eliminating the noise effective.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: air draft noise elimination passage, comprise ventilation fan, sound absorber, shutter and shell, shell is the square passage of hollow, the left side of described shell has first air outlet, the right side of outer casing bottom has second air outlet, and the second air outlet place is equipped with shutter, in the inside of described shell sound absorber and ventilation fan is installed successively from left to right.
Described shell is combined by corrosion resistant plate, galvanized sheet and glass wool.
The beneficial effect that the utility model is compared with prior art had is:
1, the utility model reasonably has been used in combination sound absorber and ventilation fan, and ventilation fan is taken a breath, and sound absorber is eliminated the noise, and makes that the utility model noise is very little.
2, shell of the present utility model is combined by corrosion resistant plate, galvanized sheet and glass wool, cooperates sound absorber and ventilation fan, has well completely cut off extraneous noise.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the utility model air draft noise elimination passage;
Among the figure: 1 is ventilation fan, and 2 is sound absorber, and 3 is shutter, and 4 is shell, and 5 is first air outlet, and 6 is second air outlet.
The specific embodiment
As shown in Figure 1, the utility model air draft noise elimination passage, comprise ventilation fan 1, sound absorber 2, shutter 3 and shell 4, shell 4 is the square passage of hollow, the left side of described shell 4 has first air outlet 5, the right side of shell 4 bottoms has second air outlet, 6, the second air outlets, 6 places shutter 3 is installed, and in the inside of described shell 4 sound absorber 2 and ventilation fan 1 is installed successively from left to right.
Described shell 4 is combined by corrosion resistant plate, galvanized sheet and glass wool.
The utility model can be installed in the roof and use, and in the roof perforate, second air outlet 6 that this air draft noise elimination passage is equipped with shutter 3 is with after the hole on roof is aimed at, and the utility model is fixed on the roof get final product.
