Abstract
The utility model provides an explosionproof fan, motor support including explosion -proof motor body and fixed explosion proof machine, the explosion proof machine sets up in motor support middle part, motor support both ends all are equipped with explosion -proof casing, the explosion -proof casing inboard at motor support both ends is equipped with the deflector, the explosion proof machine output is equipped with the flabellum, flabellum one side is equipped with the filter screen, the explosion -proof casing inboard is fixed in at the filter screen both ends. Explosionproof fan has increased the suction that debris had been stopped to the filter screen, avoids debris also can consequently not produce the spark simultaneously with the flabellum damage and leads to the mist explosion. Explosion proof machine left side is equipped with size that the deflector has reduced the gas outlet and increases that the better utilization of the gaseous velocity of flow is gaseous to make the explosion proof machine cooling, and the gaseous cooling of using self suction reduces and sets up the cost -push that the heat sink brought alone.
Description
Technical field
The utility model relates to a kind of blower fan, is specifically related to a kind of explosion-proof fan.
Background technique
Blower fan is widely used in construction industry and mineral industry, especially in mineral industry, if Explosion of blower will bring loss difficult to the appraisal, the more existing blower fan with explosion-proof effect, only take hard casing to be effective, but effect is not fully up to expectations.
How to deal with problems in minimizing Explosion of blower reason is the new direction that we face, to reduce the probability of quick-fried machine to reach explosion-proof effect, damage and blast that the working environment that blower fan uses makes blower fan often suck stone one class hard object to cause blower fan, the long-time serviceability temperature of same motor raises the possibility that also greatly can increase quick-fried machine.
Model utility content
The technical problems to be solved in the utility model overcomes existing defect, and provide a kind of explosion-proof fan, life cycle is long, with low cost, effectively can solve the problem in background technique.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
The utility model provides a kind of explosion-proof fan, comprise the electric machine support of anti-explosion motor body and fixing anti-explosion motor, it is characterized in that, described anti-explosion motor is arranged in the middle part of electric machine support, described electric machine support two ends are equipped with explosion-proof housing, are provided with guide plate inside the explosion-proof housing at described electric machine support two ends, and described anti-explosion motor output terminal is provided with flabellum, described flabellum side is provided with filter screen, and described filter screen two ends are fixed on inside explosion-proof housing.
As a kind of optimal technical scheme of the present utility model, the surface coating material of described explosion-proof housing is teflon.
As a kind of optimal technical scheme of the present utility model, described guide plate coordinates with anti-explosion motor and forms outlet passageway.
The beneficial effect that compared with prior art the utility model reaches is: explosion-proof fan adds filter screen and stopped the suction of foreign material, and also can not therefore produce spark causes Mixed Gases Explosion to avoid foreign material to be damaged simultaneously by flabellum.Being provided with the flow velocity that guide plate reduces the larger gas of air outlet on the left of anti-explosion motor better utilizes gas that anti-explosion motor is lowered the temperature, and uses the gas of self suction to lower the temperature to reduce to arrange separately the cost that cooling device brings and increase.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.
In the accompanying drawings:
Fig. 1 is the main TV structure schematic diagram of the utility model;
Number in the figure: 1, anti-explosion motor; 2, electric machine support; 3, guide plate; 4, flabellum; 5, filter screen; 6, explosion-proof housing; 7, outlet passageway.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
Embodiment: as shown in Figure 1, the utility model provides a kind of explosion-proof fan, comprise the electric machine support 2 of anti-explosion motor body and fixing anti-explosion motor 1, described anti-explosion motor 1 is arranged in the middle part of electric machine support 2, described electric machine support 2 two ends are equipped with explosion-proof housing 6, are provided with guide plate 3 inside the explosion-proof housing 6 at described electric machine support 2 two ends, and described anti-explosion motor 1 output terminal is provided with flabellum 4, described flabellum 4 side is provided with filter screen 5, and described filter screen 5 two ends are fixed on inside explosion-proof housing 6.
Further, the surface coating material of described explosion-proof housing 7 is teflon, and teflon is that a kind of high-strength material can improve case strength greatly.
Further, described guide plate 3 coordinates with anti-explosion motor 1 and forms outlet passageway 7, and both coordinate and reduce air outlet size and increase flow velocity and better make electric motor temperature reduction.
Concrete, during use: filter screen 5 can well block entering of foreign material, more effective protection flabellum 4 is not impaired, prevents that spark causes Mixed Gases Explosion simultaneously.Explosion-proof housing 6 is the intensive aspects scribbling teflon, better protects internal structure.Undersized outlet passageway 7 can better be lowered the temperature.
Explosion-proof fan adds filter screen 5 and has stopped the suction of foreign material, and also can not therefore produce spark causes Mixed Gases Explosion to avoid foreign material to be damaged by flabellum 4 simultaneously.Being provided with the flow velocity that guide plate 3 reduces the larger gas of air outlet on the left of anti-explosion motor 1 better utilizes gas that anti-explosion motor 1 is lowered the temperature, and uses the gas of self suction to lower the temperature to reduce to arrange separately the cost that cooling device brings and increase.From the source of Explosion of blower can be caused to solve problem, well stop the probability of Explosion of blower.
Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
