Description
Technical field
The utility model is related to centrifugal blower technical field, specifically a kind of centrifugation wind with mid-game reinforcement structure
Machine impeller.
Background technology
Existing centrifugal blower fan blade wheel is made of wheel cap, wheel disc and blade, blade shape have one-board blade (including
It is plate shaped and arc-shaped) and airfoil blade.Airfoil blade generally uses hollow type structure, in hollow airfoil vanes
Portion adds reinforcing rib, its advantage is that having excellent aerodynamic characteristics, the strength and stiffness of blade are relatively high, ventilating machine pneumatic
Efficiency is higher；But disadvantage, it is also obvious that craftsmanship is more complicated, after hollow airfoil vanes generate loophole, impurity enters blade
Inside, impeller are easy disequilibrium and generate vibration.One-board blade is for airfoil blade, its advantage is that vane manufacturing
Simply, cost is relatively low；The disadvantage is that structure is relatively thin, wheel speed is relatively low, limits the pneumatic property of wind turbine to a certain degree
Energy.The shortcomings that based on above two blade profile, it is difficult to ensure while realize that art of vane is simple and blade wheel structure intensity is high
The characteristic of excellent aeroperformance can be achieved.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, is provided a kind of strong with structure novel, structure
It spends, the centrifugal blower fan blade wheel with mid-game reinforcement structure that resistance is small, aeroperformance is excellent.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of centrifugal blower fan blade wheel with mid-game reinforcement structure, including wheel disc, wheel cap, wheel hub, blade and mid-game, it is described
Wheel disc is that full weld is connect with wheel cap, and the blade and wheel hub integrally connected, blade is along wheel rotation direction circumference uniform distribution；In described
Disk is stiffener plate, is fixedly connected between adjacent blades two-by-two and respectively at blade centre position, the stiffener plate
Both ends are in triangular pyramidal.
Preferably, the shape of position is consistent between the appearance and size of the mid-game and two adjacent blades.
Preferably, the stiffener plate is that metal plate bending forms.
Preferably, the blade is single plate blade and is backward type structure.
Structure novel, structural strength is good, resistance is small, aeroperformance is excellent due to using the above structure, having for the utility model
Good advantage.
Description of the drawings
A part of attached drawing for constituting the utility model is used to provide a further understanding of the present invention.In the accompanying drawings：
Fig. 1 is the internal structure schematic diagram for the centrifugal blower fan blade wheel that the utility model has mid-game reinforcement structure.
Fig. 2 is the rearview for the centrifugal blower fan blade wheel that the utility model has mid-game reinforcement structure.
Fig. 3 is the left view for the centrifugal blower fan blade wheel that the utility model has mid-game reinforcement structure.
In figure：1, wheel disc；2, wheel cap；3, mid-game；4, wheel hub；5, blade.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-3, a kind of centrifugal blower fan blade wheel with mid-game reinforcement structure, including wheel disc 1, wheel cap 2, wheel hub 4,
Blade 5 and mid-game 3, the wheel disc 1 are that full weld is connect with wheel cap 2, and the blade 5 and 4 integrally connected of wheel hub, blade 5 is along impeller
Rotation direction circumference uniform distribution；The mid-game 3 is stiffener plate, is located between adjacent blades two-by-two and respectively at 5 interposition of blade
It sets and is fixedly connected, the stiffener plate is that metal plate bending forms, and the both ends of the stiffener plate are in triangular pyramidal.In described
The shape of position is consistent between the appearance and size of disk 3 and two adjacent blades 5, to ensure stiffener plate when fixed blade 5
Two side profiles are bonded completely with 5 profile of blade plays the role of structural strengthening, and stiffener plate is corresponding with air current flow direction
Fully reduce the flow resistance of fluid.Mid-game 3 is divided into equal amount according to 5 quantity of blade, and every part passes through bending；The blade
5 are single plate blade and are backward type structure.
After being reinforced by mid-game 3, the deformation of 3 position of mid-game is obviously reduced impeller under the influence of centrifugal force, and mid-game 3 adds
The design of the trigonal pyramidal structure of strengthening tendons plate both sides makes stiffener plate increase to a certain extent with 5 contact area of blade, increases
Forced area enhances the structural strength of impeller so that blade 5 and mid-game 3 can reduce abrasion to a certain extent, and increase makes
With the service life, while corresponding centrifugal stress also reduces, the safety coefficient of structural strength when improving impeller operation.In addition impeller rotates
When to airflow function, air-flow, which along impeller inlet flows to outlet port the steering of air-flow occurs, to be changed, therefore air-flow is along arc
Line direction is gradually transitions impeller outlet and is discharged, and determines that air-flow flows arc direction by fluid simulation, and by 3 bending of mid-game
So that it is consistent as possible with flow direction, fully reduce the aerodynamic drag of mid-game 3 and play certain guide functions, impeller is made to have
There is higher pneumatic efficiency.
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art is come
Say, still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
