Abstract
The utility model relates to the technical field of axial flow fans, in particular to an explosion-proof axial flow fan which comprises a square outer shell and a round inner shell. The inner shell is arranged inside the outer shell, a louver support mounted on the outdoors is arranged at one end of the outer shell and one end of the inner shell, and a safety net for filtering air dust is arranged at the other end of the outer shell and the other end of the inner shell. A motor support is arranged on the inner shell, an explosion-proof motor is fixedly mounted on the motor support, a hub is arranged on the explosion-proof motor in the axial direction and provided with blades, and louvers are arranged on the louver support. The explosion-proof axial flow fan is simple in structure and reasonable in design, the service life of the axial flow fan is prolonged, the explosion-proof and corrosion-proof effects are good, the ventilation effect is good, safety accidents can be effectively avoided, and safe operation of production is facilitated.
Description
Technical field
The utility model relates to axial-flow blower technical field, especially a kind of conveying for inflammable gas and the explosion-proof axial flow fan of vented exhaust that has the occasion such as workshop, warehouse of easy fuel spray.
Background technique
Axial-flow blower, is exactly the blower fan with the equidirectional air-flow of axle of fan blade, because gas is parallel to fan shaft, flows, and is usually used in the occasion that flow is higher and pressure requirement is lower, promotes that air moves.For the conveying of inflammable gas and the occasion such as workshop, warehouse that has easy fuel spray, axial-flow blower is particularly important.Traditional axial-flow blower complex structure, ventilation effect is also bad, not explosion-proof also not fire-retardant, easily causes security incident, is unfavorable for that the safety of production is carried out.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the explosion-proof axial flow fan that explosion-proof effect is good.
The utility model solves the technological scheme that its technical problem adopts: a kind of explosion-proof axial flow fan, there is square outer cage and circular inner casing, inner casing is built in outer cage, one end of described outer cage and inner casing is provided with and is installed on outdoor louver bracket, and the other end of outer cage and inner casing is provided with the safety net of filtered air dust; Described inner casing is provided with electric machine support, and electric machine support is installed with anti-explosion motor, and anti-explosion motor is axially arranged with wheel hub, and wheel hub is provided with blade; Described louver bracket is provided with blinds.Be provided with safety net and prevent that airborne dust from entering blower fan, the working life of extending shaft flow fan
Further, described blinds is movably articulated in louver bracket or is fixedly welded on louver bracket.
Further, described outer cage and inner casing are glass steel shell, and explosion-proof erosion is effective.
Further, described blade surface is coated with etch-proof zinc coat, and anticorrosion ability is good.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, are provided with safety net and prevent that airborne dust from entering blower fan, the working life of extending shaft flow fan; Outer cage and inner casing are glass steel shell, and blade surface is coated with etch-proof zinc coat, and explosion-proof good with anticorrosion ability, ventilation effect is good, can effectively prevent security incident, and the safety that is conducive to produce is carried out.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. outer cages in figure, 2. inner casing, 3. safety net, 4. electric machine support, 5. anti-explosion motor, 6. wheel hub, 7. blade, 8. louver bracket, 9. blinds.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Explosion-proof axial flow fan as shown in Figure 1, there is square outer cage 1 and circular inner casing 2, inner casing 2 is built in outer cage 1, and one end of outer cage 1 and inner casing 2 is provided with and is installed on outdoor louver bracket 8, and the other end of outer cage 1 and inner casing 2 is provided with the safety net 3 of filtered air dust; Inner casing 2 is provided with electric machine support 4, and electric machine support 4 is installed with anti-explosion motor 5, and anti-explosion motor 5 is axially arranged with wheel hub 6, and wheel hub 6 is provided with blade 7; Louver bracket 8 is provided with blinds 9.
Blinds 9 is movably articulated on louver bracket 8; Outer cage 1 and inner casing 2 are glass steel shell; Blade 7 surfaces are coated with etch-proof zinc coat.
During work, start anti-explosion motor 5 and make blade 7 work, indoor air enters safety net 3, will after dust isolation, through blinds 9, deliver to outdoor.Blinds 9 has outdoor keeping off the rain, and prevents that rainwater from entering blower fan, the working life of extending shaft flow fan.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
