Abstract
The utility model discloses a vane wheel for a draught fan. Blade frameworks are evenly placed on the external circle of a shaft sleeve at intervals. Blades are movably fixed on the blade frameworks and are composed by bonding wear-resisting rubber sheets and blade lining plates. The vane wheel for the draught fan has the advantages of being good in wear-resisting performance, long in service life, easy to replace and low in use cost.
Description
Technical field
The utility model belongs to the blower fan technical field, especially relates to a kind of draught fan impeller of replaceable blade.
Background technique
At present, existing draught fan impeller is in order to strengthen the wear resistance of blade, the method of the wear resistance of most employing reinforced blades solves, as adopting the blade by the wear resistance electrode built-up welding, although this mode has increased the wear resistance of impeller, but picture is used on the more abominable blower fan of the working environment such as road sweeper tool, the scurf resistance of impeller is still very low, working life is very short, and behind blade wear, can not repair, can only change whole impeller assembly, user cost is too high, and the direct impact blades of sandstone that enters at a high speed simultaneously blower fan is sent very large noise.
Summary of the invention
The purpose of this utility model provide with the deficiency of improving prior art that a kind of impeller abrasion-proof is good, long service life, blade exchanging is convenient, user cost is low draught fan impeller.
The purpose of this utility model is achieved in that a kind of draught fan impeller, is characterized in that the interval evenly is provided with the blade skeleton on the excircle of axle sleeve, and blade is movably fixed on the blade skeleton.
In order further to realize the purpose of this utility model, can be that blade is that wear-resistant rubber sheet and blade liner plate are bonded together composition.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model employing interval on the excircle of axle sleeve evenly is provided with the blade skeleton, blade is movably fixed on the blade skeleton, changed the integral structure of common draught fan impeller, after blade wear arrives to a certain degree, can dismantle easily blade changes, need not change again whole draught fan impeller, thereby greatly prolonged the life cycle of impeller and reduced user cost, each blade has guaranteed good conformity, its quality, shape, the distance of mounting hole is the same, blade just is equivalent to a standard piece like this, is convenient to change; Wear-resistant rubber sheet and blade liner plate are bonded together the composition blade, have prolonged leaf longevity and have reduced operating noise.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Embodiment
Embodiment 2, and a kind of draught fan impeller with reference to Fig. 2, is on embodiment 1 basis, and blade 3 is that wear-resistant rubber sheet 4 and blade liner plate are bonded together composition, and other and embodiment 1 are identical.
Claims (2)
1. a draught fan impeller is characterized in that the interval evenly is provided with blade skeleton (2) on the excircle of axle sleeve (1), and blade (3) is movably fixed on the blade skeleton (2).
2. a kind of draught fan impeller according to claim 1 is characterized in that blade (3) is that wear-resistant rubber sheet (4) and blade liner plate are bonded together composition.
