Description
Technical field
The utility model is related to be tied to leafy with the backward bilayer that comes into leaves before centrifugal type wind wheel technical field, more particularly to one kind
The centrifugal type wind wheel of structure.
Background technology
It is air inlet through hollow shaft that centrifugal type wind wheel, which refers to, radial outlet air, is done work using centrifugal force (depending on rotating speed and outer diameter), makes air
Improve the wind wheel of pressure.
Existing wind wheel is typically single forward-type wind wheel or single backward type wind wheel.Forward direction multi-blade type wind wheel is in
It is widely used in wind turbine, in the application of some actual conditions, the insufficient pressure of forward direction multi-blade type wind wheel causes air quantity to exist
It is largely lost in pipe network.In order to be improved to this, design a kind of preceding to the leafy centrifugal wind with the double-layer structure that comes into leaves backward
Wheel is necessary.
Utility model content
In view of the drawbacks described above of the prior art, the technical problem to be solved by the utility model is to provide before one kind to more
The centrifugal type wind wheel of leaf and the double-layer structure that comes into leaves backward.
To achieve the above object, the utility model provides a kind of preceding to leafy centrifugal with the double-layer structure that comes into leaves backward
Wind wheel, including it is preceding come into leaves wind wheel organization to multi-blade type wind wheel organization and backward type, the forward direction multi-blade type wind wheel organization with it is backward
Formula comes into leaves and is attached between wind wheel organization, and the forward direction multi-blade type wind wheel organization comes into leaves wind wheel organization rear in forward and backward formula,
The forward direction multi-blade type wind wheel organization includes front ring, middle ring and several Forword vanes, several Forword vane side surface upper ends
It is attached with front ring inner surface, several Forword vane lower ends are attached with middle ring upper surface, described backward
The formula wind wheel organization that comes into leaves includes rear ring and several backward linear leafs, several backward linear leaf upper ends with middle ring lower surface into
Row connection, several backward linear leaf lower ends are attached with rear ring upper surface.
Several Forword vanes are uniformly distributed between front ring and middle ring.
Several backward linear leafs are uniformly distributed between middle ring and rear ring.
The middle ring is identical with rear ring outer diameter, and the front ring internal diameter is identical as middle ring and rear ring outer diameter.
The middle ring internal diameter is more than rear ring internal diameter.
The utility model has the beneficial effects that：The present apparatus increases backward type and comes into leaves wind in the bottom of forward direction multi-blade type wind wheel
Wheel, can increase the pressure of fan operation, can overcome the resistance of pipe system of bigger, terminal air output bigger.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the front view of the utility model.
Fig. 3 is the vertical view of the utility model.
Fig. 4 is the sectional view of the utility model.
Specific implementation mode
As shown in Figure 1,2,3, 4, to the leafy centrifugal type wind wheel with the double-layer structure that comes into leaves backward before a kind of, including it is preceding to more
Leaf formula wind wheel organization and backward type come into leaves wind wheel organization, which is characterized in that the forward direction multi-blade type wind wheel organization and backward type are long
It is attached between blade wind-wheel mechanism, the forward direction multi-blade type wind wheel organization comes into leaves wind wheel organization rear in forward and backward formula, described
Forward direction multi-blade type wind wheel organization includes front ring 1, middle ring 2 and several Forword vanes 3,3 side surface upper end of several Forword vanes
It is attached with 1 inner surface of front ring, several 3 lower ends of the Forword vane are attached with 2 upper surface of middle ring, after described
Include rear ring 4 and several backward linear leafs 5 to the formula wind wheel organization that comes into leaves, several 5 upper ends of backward linear leaf under middle ring 2
Surface is attached, and several 5 lower ends of backward linear leaf are attached with 4 upper surface of rear ring.
Several Forword vanes 3 are uniformly distributed between front ring 1 and middle ring 2.
Several backward linear leafs 5 are uniformly distributed between middle ring 2 and rear ring 4.
The middle ring 2 is identical with 4 outer diameter of rear ring, and 1 internal diameter of the front ring is identical as middle ring 2 and 4 outer diameter of rear ring.
2 internal diameter of the middle ring is more than 4 internal diameter of rear ring.
As shown in Figs 1-4, the present apparatus comes into leaves wind wheel organization before being divided into multi-blade type wind wheel organization and backward type first.Forward direction
Multi-blade type wind wheel organization and backward type come into leaves and are attached between wind wheel organization, and forward direction multi-blade type wind wheel organization is in forward and backward formula
Wind wheel organization come into leaves rear.Middle ring 2 is identical with 4 outer diameter of rear ring, and 1 internal diameter of front ring is identical as middle ring 2 and 4 outer diameter of rear ring.In middle ring 2
Diameter is more than 4 internal diameter of rear ring.Structure accordingly, therefore Forword vane 3 is uniformly distributed between front ring 1 and middle ring 2 and by 1 He of front ring
Middle ring 2 is fixed.Backward linear leaf 5 is uniformly distributed between middle ring 2 and rear ring 4 and is consolidated by middle ring 2 and rear ring 4
It is fixed.And because the bottom of Forword vane 3 can increase the pressure of fan operation to linear leaf 5 after increase, bigger can be overcome
Resistance of pipe system, terminal air output bigger.
The preferred embodiment of the utility model described in detail above.It should be appreciated that the ordinary skill people of this field
Member according to the present utility model can conceive without creative work makes many modifications and variations.Therefore, all this technology necks
Technical staff passes through logic analysis, reasoning or limited reality on the basis of existing technology according to the design of the utility model in domain
Available technical solution is tested, it all should be in the protection domain being defined in the patent claims.
