Technical field
The utility model relates to a kind of centrifugal blower.
Background technique
Along with producing and scientific and technical development, ventilator is increasingly extensive in the application in national economy field, and whole industrial economy is had to important impact.Blower fan is one of equipment of generally using of each factory, enterprise, and particularly the application of ventilator is more extensive.Boiler air blast, removing smoke and dust, the cooling blower fan that all be unable to do without of ventilation, in power station, mine, chemical industry and environment-friendly engineering, ventilator is indispensable visual plant especially, correctly grasps the design of blower fan, is very important to the normal economical operation that ensures blower fan.Centrifugal blower is generally used for the room ventilation ventilation of the buildings such as factory, also can be used for the high pressure forced ventilation of boiler, forge etc., and is applied to the occasions such as mass transport.Traditional centrifugal blower can not adapt to high-temperature work environment; overheated air temperature usually can cause the loss of part and the unsafe condition of internal power source; and the material heat-resisting effect that the intake grill of traditional centrifugal blower and exhaust outlet use is poor; oxidizable, shorten working life of centrifugal blower.
Model utility content
The technical problems to be solved in the utility model is to provide one and utilizes exterior motor that power source is provided, and can dispel the heat in inside, and its heat-resisting effect is good, not oxidizable, long service life, the centrifugal blower of more applicable high-temperature work environment.
For addressing the above problem, the utility model adopts following technological scheme: a kind of centrifugal blower, comprise a ventilator body, described ventilator body exterior is provided with motor, on described ventilator body, be provided with V band belt wheel, bearing support, main shaft, reel, fan blade, spiral case, sink, ventilated port, intake grill, exhaust outlet and base, described motor is positioned at ventilator outside, described V band belt wheel, bearing support, sink is connected by main shaft successively with reel, described spiral case, reel is all fixedly connected with main shaft with fan blade, described ventilated port is positioned at spiral case top, and be provided with more than one, lay respectively at the positive and negative both sides of spiral case, described intake grill and exhaust outlet are all arranged on spiral case, described V is provided with the V band being connected with motor with belt wheel, on described bearing support, be provided with cooling unit, on described intake grill and exhaust outlet, be all provided with refractory metal layer.
As preferably, described intake grill is shaped as large type tube taper, and horizontal position is higher than exhaust outlet.
As preferably, described cooling unit is motor bearings oil cooler.
As preferably, described sink is flabellum heat radiation, and is innerly connected with mainshaft gear.
As preferably, described refractory metal layer is refractory Fe-base alloy metal layer.
The beneficial effect of the utility model centrifugal blower is: owing to being provided with exterior motor, can Yin Gaowen and cause power source in unsafe condition, owing to being provided with sink and ventilated port with matching, can utilize power source that internal heat is discharged, reduce centrifugal blower inside temperature, due to intake grill and exhaust outlet being set, and intake grill is shaped as large type tube taper, horizontal position is higher than exhaust outlet, after can better making high-temperature gas enter intake grill, discharge, owing to being provided with refractory metal layer, not oxidizable, extend the working life of centrifugal blower.
