Description

Pneumatic power induced-draft fan

Technical field

The utility model Pneumatic power induced-draft fan belongs to the smoke ventilator technical field, especially a kind ofly source of the gas is placed on away from inflammable and explosive place the smoke ventilator that separates with fan body.

Background technique

At present, mainly contain two kinds of smoke ventilators of electromechanical and water drive dynamic formula on the market.220 volts of Ac smoke exhaust fans can bear the smoke evacuation under the high temperature, and exhaust air rate is bigger, and motor starts easily, rotating speed is very fast, and exhaust smoke level is big, is present public security fire-fighting army fume extractor commonly used, but its shortcoming is can't use under the situation of power supply not having, and can't use in inflammable and explosive place.Centrifugal petrol power smoke ventilator is easy to generate the gasoline leakage and causes stopping working in scene of fire Yin Gaowen anoxic.With regard to exhaust smoke level, electronic smoke ventilator can reach the 9000-10000 cubic meter/hour, the gasoline smoke ventilator can reach 4500 cubic metres/hour.The fuselage deadweight has a direct impact fire fighter's scene of a fire operation, the Ac smoke ventilator of general 26 kilogram weights, at least two fire fighters just can lift movingly, and heavier gasoline smoke ventilator weighs more than 20 kilogram, this puts out a fire to save life and property to long-term operation, the large-sized fire of holding ground, and need constantly mobile scene of a fire smoke evacuation, be very disadvantageous.

The waterpower smoke ventilator is a kind of novel intrinsic safe explosion-proof type fire service equipment, has smoke evacuation function and smoke elimination function.The waterpower smoke ventilator that disappears utilizes press water as power, by the water turbine high speed rotating, drives blower fan and produces air quantity, reaches scene of a fire smoke discharging effect, and simultaneously, press water produces a large amount of thin water smoke through atomization spray cap, reaches scene of a fire smoke effect.But in actual application, particularly in the special fire situation of can not water putting out a fire to save life and property, as library, computer room, archives etc.Cause water damage easily, cause the consequence that to retrieve.Also do not have a kind ofly not need power initiation in the market, be difficult for smoke ventilator flame-out, in light weight, that can not cause secondary to injure to property.

The model utility content

The purpose of the utility model Pneumatic power induced-draft fan be for overcome existing product be motor-driven smoke ventilator under the situation of the scene of a fire because outage, high temperature anoxic cause flame-out and water-driven smoke ventilator easily to cause the disadvantage of water damage easily, a kind of restriction that is not subjected to any occasion is provided, can have given play to the Pneumatic power induced-draft fan of best smoke discharging effect to greatest extent.

The technological scheme of the utility model Pneumatic power induced-draft fan is: Pneumatic power induced-draft fan mainly comprises: housing, fan and source of the gas, housing is a hollow cylinder, on the outer wall of housing, frame is installed, bottom in frame is equipped with universal wheels, upper outside in frame is equipped with handle, the shell of power converter is weldingly fixed on the central position of housing inner chamber by cross support, one end of power converter connects the main shaft of fan, the other end of power converter connects the outlet of tee union by valve, the import of tee union connects the source of the gas outlet by tracheae, is placed with source of the gas on the chassis of frame;

Tee union comprises mobile aeration pump joint, automobile air pump joint, inflation gas cylinder joint.

The utility model Pneumatic power induced-draft fan compared with prior art has following beneficial effect:

1, safe in utilization, be widely used: because source of the gas is connected with fan by long arbitrarily tracheae, tee union, valve, power converter, source of the gas can be placed on away from inflammable and explosive place, housing is placed in the occasion that needs smoke evacuation, just can use safely, be specially adapted to various occasions such as inflammable and explosive, tall building, subsurface construction, tunnel underground, industrial and mining enterprise.

2, move easily, exhaust smoke level is big: this small product size is little, in light weight, is easy to promote, and also can hang, and can not cause secondary to damage to the scene of needs smoke evacuation, and smoke discharging effect is good, exhaust smoke level can reach the 4000-6000 cubic meter/hour.

3, convenient and practical, cost is low: the air supply source of smoke ventilator has multiple choices, can be with inflating gas cylinder, also can use external gas-filled pump, even directly can be connected with the air pump of vehicle, and cost only is similar motor-driven smoke ventilator and water drive ejector half smoke ventilator 1/4th, and therefore higher promotional value is arranged.

Description of drawings

Fig. 1 is the structural representation of the utility model Pneumatic power induced-draft fan;

Fig. 2 is the left view of Fig. 1;

Fig. 3 is the utility model Pneumatic power induced-draft fan embodiment 2 a structural representation.

As shown in the figure: the 1-housing, the 2-support, the 3-fan, the 4-power converter, the 5-source of the gas, the 6-universal wheels, the 7-tracheae, the 8-valve, the 9-tee union, the outlet of 10-source of the gas, the 11-handle, the 12-frame, the telescopic smoke-ejecting pipe of 13-, 14-moves air pump.

Embodiment

As Fig. 1, shown in Figure 2, Pneumatic power induced-draft fan mainly comprises housing 1, fan 3, source of the gas 5, telescopic smoke-ejecting pipe 13, housing 1 is that hollow cylinder is connected with telescopic smoke-ejecting pipe 13, the shell of power converter 4 is weldingly fixed on the central position of housing 1 inner chamber by cross support 2, one end of power converter 4 connects the main shaft of fan 3, the other end of power converter 4 connects the outlet of tee union 9 by valve 8, the import of tee union 9 connects source of the gas outlet 10 by tracheae 7, on the chassis of frame 12, be placed with source of the gas 5, frame 12 is installed on the outer wall of housing 1, in the bottom of frame 12 universal wheels 6 is installed, upper outside in frame 12 is equipped with handle 11, and tee union comprises mobile aeration pump joint, automobile air pump joint, inflation gas cylinder joint.
