Abstract
The utility model relates to a propeller composite cone blade, which is characterized in that the thickness of the wind inlet position A of the blade 1 and a disk root position B are enhanced, wherein, the thickness of the blade is gradually enhanced towards the wind inlet position A and the disk root position B, wherein, the thickness of the blade is gradually enhanced towards the wind inlet position to form an inclined plane, and the included angle gamma of the inclined plane and a horizontal plane is 8-12 DEG. The utility model enhances the time of the abrasion of the blade due to the structure, can keep the blade not being worn out in loner time, and can make the service life of the action of a rotor of a fan extended by 2-3 times.
Description
The utility model relates to the improvement of the impeller of power equipments such as wheeled blower fan, compressor, particularly a kind of impeller compound taper blade.
At present, improving the wear-resistant means of blade has: change material character, increase corresponding hardness; Adopt overlaying method to change the character of blade surface, increase wear-resistant ability; Rationally change structure and size, rotating speed etc., change the flow condition in flow field; Increase thickness, prolong the wear-out period etc.Though described method or measure can be received certain effect, flow and the abrasion mechanism essential problem owing to take into full account the two-phase of flow of flue gas, therefore still can not remove smoke fully to the dust stratification of wearing and tearing, corrosion and the blade of blade.
The purpose of this utility model provides a kind of impeller compound taper blade that can effectively improve wear resistance.
Above-mentioned purpose of the present utility model is to realize that by such technological scheme promptly a kind of impeller compound taper blade is characterized in that: the thickness at blade intake grill place and packing place increases.
Said structure of the present utility model is further specified by accompanying drawing
The utility model has following accompanying drawing:
Accompanying drawing 1 is the plan view of the utility model structure;
Accompanying drawing 2 is the side view of the utility model structure.
Referring to accompanying drawing: the impeller compound taper blade characteristics among the figure is: the thickness at blade 1 A of intake grill place and the B of packing place increases.Known to accompanying drawing, the thickness of blade increases gradually to A of intake grill place and the B of packing place, and wherein vane thickness increases and the inclined-plane that constitutes and the angle r of horizontal plane are 8-12 ° gradually to the intake grill place.
The utility model can keep blade not to be worn through in the long time owing to described structure has increased time of blade wear, can make the fan rotor working life prolong 2-3 doubly.
Claims (2)
1. an impeller compound taper blade is characterized in that: in the thickness increase of blade (1) intake grill place (A) and packing place (B).
2. impeller compound taper blade according to claim 1, it is characterized in that: the thickness of blade increases gradually to intake grill place (A) and packing place (B), and wherein vane thickness increases and the inclined-plane that constitutes and the angle r of horizontal plane are 8-12 ° gradually to the intake grill place.
