Abstract
The utility model provides a double-air-inflow three-dimensional flow impeller, which is characterized in that three-dimensional flow blades are distributed at the two sides of an impeller disc and are symmetrically arrayed by taking the impeller disc as a symmetry plane, splitter blades which are shaped like a streamline and are arrayed at intervals are arranged between the three-dimensional flow blades, the gap between two adjacent three-dimensional flow blades is 10-20cm, the splitter blades are positioned at midpoint positions between every two three-dimensional flow blades, the number of the three-dimensional flow blades and the number of the splitter blade are 6-18 respectively, the height of the splitter blades is 60-80% of that of the three-dimensional flow blades, and the splitter blades and the three-dimensional flow blades at the equal altitude are the same in width. The three-dimensional flow blades are preferably and integrally made of forging aluminum or stainless steel materials, air flow at the air outlet of the double-air-inflow three-dimensional flow impeller is not easy to block, so that the double-air-inflow three-dimensional flow impeller can be used for manufacturing fans with large air inflow and high air outlet speed.
Description
Technical field
The utility model relates to a kind of three-dimensional flow impeller.
Background technique
Common three-dimensional flow impeller is comprised of the three-dimensional flow blade of wheel disc and wheel disc one side, can only single admission, and the restricted bottleneck of air output.
Number of patent application is a kind of mounting device for blade of external rotor axial-flow fan of CN201110212723.4, and it relates to field of machining and machinebuilding technology; It comprises device body (1), abutted flange mounting hole (2), axial blade mounting hole (3) and from turning center (4); Device body (1) is enclosed within from turning on center (4), and fixing by corresponding abutted flange mounting hole (2), adopt the axial blade of bi-directional design by axial blade mounting hole (3), to be arranged on the ear in the outside of device body (1); It is simple in structure, even from turning center, also can realize the exchange of axial flow centrifugal impeller in the situation that do not change, and because axial blade adopts bi-directional design, when needs changed wind direction, the direction that the direction that only needs to adjust blade can change the blower fan air-out got final product.This axial blade adopts the bi-directional design of wheel disc the same side, though the exhaust outlet wind direction can change, intake grill can not be introduced two-way distinguished and admirable, and air output is less, and compression efficiency is not high.
Summary of the invention
The purpose of this utility model: provide a kind of and have respectively the three-dimensional flow blade in the wheel disc both sides, and have splitterr vanes, air inflow is large, the fireballing pair of air inlet three-dimensional flow impeller of giving vent to anger.
Technological scheme: to achieve these goals, the two air inlet three-dimensional flow impellers of the utility model, have wheel disc and three-dimensional flow blade.For wrought aluminium or stainless steel are whole, manufacture and form, become one whole through the Cutter Body Processing with Machining Center manufacture of five-axle linkage.Described three-dimensional flow Leaf positional distribution is at the bilateral of wheel disc, and the three-dimensional flow blade of bilateral be take wheel disc and is the symmetry plane symmetric arrays; The similar splitterr vanes of streamline shape are separately arranged, alternately between the three-dimensional flow blade; Splitterr vanes are also the streamline blades in ternary space, and the splitterr vanes height is the 60-80% of three-dimensional flow blade height.
The quantity of described three-dimensional flow blade and splitterr vanes can be respectively 6-18.
Interval between adjacent two described three-dimensional flow blades can be 10-20cm, and splitterr vanes are preferably placed at two neutral positions between the three-dimensional flow blade.
The described wheel disc of take is the horizontal plane metering, the equal altitudes place, and the splitterr vanes of selecting are identical with the width of three-dimensional flow blade.
Beneficial effect:Rapidly and efficiently, place, air outlet air-flow should not block, and can be used for manufacturing air inflow large, the fireballing blower fan of giving vent to anger in air inlet of the present utility model.
The accompanying drawing explanation
Fig. 1 is perspective view of the utility model;
In figure: 1, wheel disc; 2, three-dimensional flow blade; 3, splitterr vanes; 4, the interval between the three-dimensional flow blade; 5, three-dimensional flow blade height; 6, axis hole.
Embodiment
