Abstract
The utility model relates to a wearproof vane wheel of a centrifugal fan. The utility model comprises a wheel cover 1, leaf blades 3 and a rear disk 4. The utility model is characterized in that flow distribution plates 2 are fixed on the leaf blades 3 and are parallel with the wheel cover 1, and inlet diameters of the flow distribution plates 2 equal the inlet diameter of the wheel cover. Through the additional arrangement of the flow distribution plates, the utility model changes the airflow direction of air flowing into a vane wheel, and the air can generate flow distribution to lessen scouring force to the rear disk and the leaf blades on a lower part; therefore, the wearing resistance of the vane wheel is improved, and the service life of the vane wheel of a fan is extended.
Description
The utility model relates to the abrasionproof impeller of a kind of impeller, particularly a kind of centrifugal blower.
Often contain a certain amount of dust in all gases medium that industrial fan is carried, some dust not only particle is bigger, its hardness is also higher, as the air bells exhauster of steel mill's steel making furnace, the boiler induced-draft fan of power plant, the kiln tail blower fan in cement plant, the particle that contains high hardness such as a large amount of iron oxide, coal dust, carbon stone in the medium that they are carried, when carrying, these particles are washing away the working surface of draught fan impeller, make its wearing and tearing, destruction, shortened the working life of impeller, operation cycle of some impeller even have only a week.For prolonging the working life of impeller, the working surface built-up welding one deck wearing layer at impeller is also arranged, as tungsten carbide material layer or stickup ceramic plate, but high, the complex process of manufacture cost of this impeller.
The purpose of this utility model is to provide a kind of long service life, the abrasionproof impeller of the centrifugal blower of low cost of manufacture.
The utility model is achieved in that a kind of abrasionproof impeller of centrifugal blower, comprises wheel cap, blade, hub disk, it is characterized in that: be fixed with flow distribution plate on the described blade.
In order to reach shunting effect preferably, do not influence fan performance again simultaneously, flow distribution plate is fixed on blade central authorities, and parallel with wheel cap, and the inlet diameter of flow distribution plate equates with the inlet diameter of wheel cap.
The utility model is simple in structure, low cost of manufacture, only change the airflow direction that gas flows into impeller by setting up flow distribution plate, make it produce shunting, a part is stopped by flow distribution plate and flows along flow distribution plate top, just reduced scouring force, thereby improved the wear resistance of impeller, prolonged the working life of draught fan impeller lower blade and hub disk.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1: the utility model embodiment's structural representation.
Embodiment: a kind of abrasionproof impeller of centrifugal blower, comprise wheel cap 1, blade 3, hub disk 4, it is characterized in that: be fixed with flow distribution plate 2 on the described blade 3.
As can be seen from Figure 1: flow distribution plate 2 is fixed on blade 3 central authorities, and parallel with wheel cap 1, and the inlet diameter of flow distribution plate 2 equates with the inlet diameter of wheel cap.
Claims (3)
1, a kind of abrasionproof impeller of centrifugal blower comprises wheel cap (1), blade (3), hub disk (4), it is characterized in that: be fixed with flow distribution plate (2) on the described blade (3).
2, the abrasionproof impeller of centrifugal blower as claimed in claim 1 is characterized in that: described flow distribution plate (2) is fixed on described blade (3) central authorities.
3, as the abrasionproof impeller of claim 1,2 described centrifugal blowers, it is characterized in that: described flow distribution plate (2) is parallel with described wheel cap (1), and the inlet diameter of described flow distribution plate (2) equates with the inlet diameter of described wheel cap (1).
