Abstract
The utility model relates to a kind of axial fan with explosion prevention function.It comprises columnar housing, and the two ends of housing are opening shape, and its internal fixtion has motor, and the center line of this motor output shaft and the axis of housing are on the same line.The output shaft of described motor there is impeller, impeller upper blade.The outward edge being characterized in described blade is coated with copper layer, and the inwall of described housing has pressure inductor, and pressure inductor is connected with alarm buzzer by wire.This axial fan can use containing the more occasion of dust, and using scope is unrestricted.
Description
Technical field
The utility model relates to a kind of blower fan, is the axial fan with explosion prevention function specifically.
Background technique
Axial fan is easy for installation because of it, and ventilation successful is widely used in the industries such as chemical industry, medicine, mining.
At present, the axial fan used in industry comprises columnar housing, and the two ends of housing are opening shape, and its internal fixtion has motor, and the center line of this motor output shaft and the axis of housing are on the same line.The output shaft of described motor there is impeller, impeller upper blade.In order to cost-saving, impeller and the housing of axial fan are made by carbon steel.Axial fan in use for some time, there will be the phenomenon that impeller loosens, make impeller when rotated, between the outward edge of its upper blade and inner walls, frictional impact occurs, the carbon in carbon steel can come off because of friction, and easily produces spark, when the occasion (as flour mill, machine shop) that dust solubility is higher uses, may cause dust explosion, so traditional axial fan cannot use containing the more occasion of dust, using scope is limited.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of axial fan with explosion prevention function, and this axial fan can use containing the more occasion of dust, and using scope is unrestricted.
For solving the problem, provide following technological scheme:
The axial fan with explosion prevention function of the present utility model comprises columnar housing, and the two ends of housing are opening shape, and its internal fixtion has motor, and the center line of this motor output shaft and the axis of housing are on the same line.The output shaft of described motor there is impeller, impeller upper blade.The outward edge being characterized in described blade is coated with copper layer, and the inwall of described housing has pressure inductor, and pressure inductor is connected with alarm buzzer by wire.
Wherein, described alarm buzzer is arranged on the outer side wall of housing.
Take above scheme, have the following advantages:
The outward edge with the axial fan blade of explosion prevention function of the present utility model is coated with copper layer, and the inwall of described housing has pressure inductor, and pressure inductor is connected with alarm buzzer by wire.When blade and inner walls generation frictional impact, due to the heat-conducting property that copper is good, the heat of generation can be absorbed and be conducted, and copper itself is relatively soft, carbon containing hardly, there is good deformability when friction and shock, not easily produce dust material, thus can not spark be produced.Simultaneously when blade and inner walls generation frictional impact, pressure inductor can convert the pressure information of inner walls to electrical signal transfer to alarm buzzer, when alarm buzzer detects that the force value that pressure inductor passes over is excessive, can give the alarm, staff can maintain axial fan or change after hearing alarm, avoids blade and the long-time frictional impact of inner walls destroys copper layer and creates the phenomenon of burning.So the occasion that this axial fan is used in containing dust is more also not easily sets off an explosion, using scope is unrestricted.
Accompanying drawing explanation
Fig. 1 be of the present utility model have the axial fan of explosion prevention function structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the axial fan with explosion prevention function of the present utility model comprises columnar housing 1, and the two ends of housing 1 are all processed as opening shape, and its internal fixtion has motor 2, and the center line of this motor 2 output shaft and the axis of housing 1 are on the same line.The output shaft of described motor 2 is connected with impeller 3, impeller 3 is arranged blade 4.The outward edge of described blade 4 is coated with copper layer 5, the inwall of described housing 1 has pressure inductor 6, the outer side wall of described housing 1 has alarm buzzer 7, and pressure inductor 6 is connected with alarm buzzer 7 by wire.
During use, starting electrical machinery 2, the output shaft of motor 2 rotates with impeller 3, can reach the effect of ventilation.The occasion that the axial fan with explosion prevention function of the present utility model uses dust solubility higher not easily sets off an explosion.
