Description
Technical field
The utility model relates to the ventilation smoke exhaust technical field, relates to a kind of Pneumatic power induced-draft fan specifically.
Background technique
The fume extractor commonly used of fire-fighting at present is generally electromechanical and two kinds of smoke ventilators of water drive dynamic formula.Dynamo-electric smoke ventilator is not having under the situation of power supply or inflammable and explosive place can't be used.Centrifugal petrol power smoke ventilator is easy to generate the gasoline leakage and the Yin Gaowen anoxic causes stopping working in the scene of fire.The waterpower smoke ventilator has explosion-proof type smoke evacuation function and smoke elimination function.But in actual application, particularly,, cause unknown losses such as water damage easily like library, computer room, archives etc. in the special fire situation of can not water putting out a fire to save life and property.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned defective, and a kind of Pneumatic power induced-draft fan is provided.
In order to realize the purpose of the utility model, the technological scheme that the utility model adopts is:
A kind of Pneumatic power induced-draft fan comprises cylinder shell, support, protective net; Blade, fixing frame, central shaft; Equalizer bearing, pneumatic pump, gas supply station; Said gas supply station is connected with said pneumatic pump, and said pneumatic pump is connected with said central shaft and drives said central shaft rotation, and said central shaft is passed said equalizer bearing and said blade; Said vanes fixed is installed on the said central shaft, and said pneumatic pump and said equalizer bearing are fixed on said cylinder shell inside through said fixing frame, and said protective net is installed on the two-port of said cylinder shell; Said cylinder shell is installed on the said support, and said blade has two groups, and said equalizer bearing also has two groups.
Said gas supply station comprises the gas collection connecting pipeline; Gas cylinder; Decompressor, high pressure resistant valve, high-pressure manometer, said gas cylinder is communicated on the said gas collection connecting pipeline through said decompressor and said high pressure resistant valve, and said high-pressure manometer is installed on said gas cylinder and said decompressor between connecting tube.
Said gas cylinder, decompressor, high pressure resistant valve, high-pressure manometer respectively have four groups.
Said high-pressure manometer is the high-pressure manometer of band overbottom pressure alarm.
The two-port of said cylinder shell connects gas exhaust duct and smoking pipeline respectively.
The beneficial effect of the utility model is: 1, conveniently moving, and easy and simple to handle, be widely used, do not having under the situation of power supply or inflammable and explosive place also can proper functioning, be fit to the operation of taking out, discharge fume under the multiple environmental conditions.2, the design of two fan blades can strengthen exhaust smoke level greatly.3, the timely prompting changing gas cylinder of overbottom pressure alarm has been avoided shutting down and has been changed gas cylinder.
