Abstract
A blade structure of an axial flow fan comprises blades, the blades are of airfoil type structures and are mounted between an impeller rotary hub A and an impeller rotary hub B, the blades are arranged in a local superposition structure, the directions of the blades are of outward diffuse structures, the blades are of land-effect airfoil type structures, according to the blade structure of the axial flow fan provided by the utility model, the airfoil type blades can ensure the high efficiency and low noise of the fan and can optimize the optimum running point of the fan. The utility model has advantages of simple structure, convenient manufacturing and mounting. low cost and good using effect.
Description
Technical field
The utility model relates to a kind of blade structure of axial-flow blower, belongs to the industrial fan product technical field.
Background technique
A large amount of at present at the AXA/B of industrial use profile shaft flow fan, mainly be by: draught fan impeller, Blower Housing, motor are constituted, the axial-flow blower of this structure type, the blade structure of its draught fan impeller is lamellar arc drawing blade structure, and the blade of this structure gently approaches, and in use is easy to distortion, thereby influence the aerodynamic performance of blower fan, the best operating point of blower fan just can not be optimised, influences the usability and the working efficiency of blower fan, and the noise of blower fan is also bigger.
Summary of the invention
The utility model provides a kind of blade structure of a kind of axial-flow blower of novelty, adopts the wing blades structure technology, to realize good low noise performance of axial-flow blower and the purpose that improves aerodynamic performance.
The technical solution adopted in the utility model is:
A kind of blade structure of axial-flow blower comprises: blade, and described blade is the wing blade structure blade, and being installed on impeller changes between hub A, the impeller commentaries on classics hub B, is local superimposed shape structural arrangement between the blade, and direction is for outwards being the divergent shape structure.
Blade is a ground effect type wing blade structure blade.
The utility model beneficial effect is:
Owing to adopted the blade structure of a kind of axial-flow blower of the present utility model, wing blades has guaranteed the efficient and low noise of blower fan, optimize the best operating point of blower fan, the blade structure of a kind of axial-flow blower of the present utility model has: simple in structure, make easy for installation, cost is low, the characteristics that using effect is good.

Among Fig. 4: blade 31, blade rotor 32, impeller changes hub A33, and impeller changes hub B34, clamping bolt nut assembly 35.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.
Blower fan, mainly by: draught fan impeller 1, Blower Housing 2, motor 3 are constituted.
Draught fan impeller 1 comprises: blade 31, blade rotor 32, impeller change hub A33, impeller changes hub B34, clamping bolt nut assembly 35 structures.
A kind of blade structure of axial-flow blower comprises: blade 31, and described blade 31 is the wing blade structure blade, and being installed on impeller changes between hub A33, the impeller commentaries on classics hub B34, is local superimposed shape structural arrangement between the blade 31, and direction is for outwards being the divergent shape structure.
Blade 31 is a ground effect type wing blade structure blade.
Basic functional principle: when blower fan starts use,, make wing blades guarantee the efficient and low noise of blower fan, realize optimizing the best operating point of blower fan, with the aerodynamic performance of raising blower fan because axial-flow blower is the wing blades structure.
Claims (2)
1. the blade structure of an axial-flow blower, comprise: blade (31), it is characterized in that: described blade (31) is the wing blade structure blade, be installed on impeller and change hub A(33), impeller changes hub B(34) between, be local superimposed shape structural arrangement between the blade (31), direction is for outwards being the divergent shape structure.
2. the blade structure of a kind of axial-flow blower according to claim 1 is characterized in that: blade (31) is ground effect type wing blade structure blade.
