Abstract
The utility model discloses a wing-type impeller. The wing-type impeller comprises two end rings and a plurality of vanes, wherein the two ends of each vane are connected with the end rings through rivet claws, and the cross section of each vane is a wing-type vane. Each vane comprises an upper vane part and a lower vane part, wherein the upper vane part and the lower vane part are separable, are bent forwards in the rotation direction and are spliced in a matched mode. Each vane of the wing-type impeller is divided into the upper vane part and the lower vane part, and therefore the wing-type impeller is novel in structure, convenient to repair and low in cost.
Description
Technical field
The utility model relates to the aerofoil impeller of a kind of impeller, particularly a kind of light-duty low speed.
Background technique
The draught fan impeller of traditional blades, noise is large, efficiency is low; Existing aerofoil impeller, its blade is all an integral body, and cost of production is low, has been subject to consumers in general's favor, but when damaging appears in blade, need to change whole blade, and this has caused certain pressure to maintenance cost.
Summary of the invention
The utility model will solve the high technical problem of blade maintenance cost in existing aerofoil impeller.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of aerofoil impeller, comprises two end circles, a plurality of blade, and the two ends of blade by riveting pawl and the riveted joint of end circle, is characterized in that: the cross section of described blade is wing blades respectively; Described blade comprises two separable upper blades and lower blade, and described upper and lower blade is along its sense of rotation to the antecurvature and splicing that can match.
Described a plurality of blade is circumference uniform distribution on end circle.
The technique effect that the utility model can reach is:
Aerofoil impeller of the present utility model in use, if blade is damaged, only needs to change damaged location affiliated upper blade or lower blade, and without changing whole blade, has saved maintenance cost.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, Fig. 2, the utility model provides a kind of aerofoil impeller, comprises two end circles 1, a plurality of blade 2, and the two ends of blade 2 are respectively by riveting pawl 5 and 1 riveted joint of end circle, and the cross section of described blade 2 is wing blades; Described blade 2 comprises two separable upper blades 3 and lower blade 4, and described upper and lower blade 3,4 is along its sense of rotation to the antecurvature and splicing that can match.
Between described upper blade 3 and lower blade 4, can rivet by riveting pawl.
Described a plurality of blade 2 is circumference uniform distribution on end circle 1.
During assembling, after upper and lower blade 3,4 is stitched together, by riveting pawl 5 and 1 riveted joint of end circle of blade 2 upper and lower end faces.
In sum, the blade on aerofoil impeller of the present utility model is divided into upper and lower blade 3,4, novel structure, and easy to maintenance, cost is low.
Claims (2)
1. an aerofoil impeller, comprises two end circles, a plurality of blade, and the two ends of blade by riveting pawl and the riveted joint of end circle, is characterized in that: the cross section of described blade is wing blades respectively; Described blade comprises two separable upper blades and lower blade, and described upper and lower blade is along its sense of rotation to the antecurvature and splicing that can match.
2. a kind of aerofoil impeller according to claim 1, is characterized in that: described a plurality of blades are circumference uniform distribution on end circle.
