Abstract
The utility model belongs to a kind of energy-efficient axial flow double-vane impeller, comprise wheel hub (3) and be provided with stabilizer (5) on back blades (4), it is characterized in that on wheel hub (3), be fixed with three primary blades (1) uniformly, below primary blades (1), be fixed with the back blades (4) of U-shaped; Current limliting block (2) is fixed with on primary blades (1); Primary blades (1) roller hub (3) side is provided with main lobe bar (6).This utility model saves the energy, in the situation that power is relatively little, can obtain larger stirring efficiency.
Description
Technical field
The utility model belongs to a kind of parts of agitator, a kind of energy-efficient axial flow double-vane impeller of special design.
Background technology
Impeller is a vitals of agitator, is related to agitator production efficiency and consumed power.The equivalent unit discharge-amount of the 3PP impeller that current application is more is lower, if will improve unit discharge-amount, just must improve power, waste energy.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, a kind of energy-efficient axial flow double-vane impeller saving energy is provided.
The technical scheme that the utility model technical solution problem adopts is: a kind of energy-efficient axial flow double-vane impeller, comprise wheel hub and be provided with stabilizer on back blades, it is characterized in that on wheel hub, be fixed with three primary blades uniformly, below primary blades, be fixed with the back blades of U-shaped; Current limliting block is fixed with on primary blades; Primary blades roller hub side is provided with main lobe bar.The knuckle of primary blades is α
1, α
1=20 ° ~ 30 °.
The beneficial effects of the utility model are: this utility model saves the energy, in the situation that power is relatively little, can obtain larger stirring efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the three-dimensional front view of energy-efficient axial flow double-vane impeller;
Fig. 2 is the top perspective view of Fig. 1;
Fig. 3 is the primary blades parts front view of Fig. 1;
Fig. 4 is the sectional view of the A-A of Fig. 3.
In figure: 1-primary blades; 2-current limliting block; 3-wheel hub; 4-back blades; 5-stabilizer; 6-main lobe bar.
Detailed description of the invention
Embodiment, with reference to accompanying drawing, a kind of energy-efficient axial flow double-vane impeller, comprises wheel hub 3 and be provided with stabilizer 5 on back blades 4, it is characterized in that on wheel hub 3, be fixed with three primary blades 1 uniformly, is fixed with the back blades 4 of U-shaped below primary blades 1; Current limliting block 2 is fixed with on primary blades 1; Primary blades 1 roller hub 3 side is provided with main lobe bar 6.The knuckle of primary blades 1 is α
1, α
1=25 °.Be connected with bolt between primary blades 1 with wheel hub 3; Wheel hub 3 center is provided with circular hole and is fixedly connected with stirrer shaft.Back blades 4 outer end is provided with stabilizer 5; For to weld or to be connected with bolt between back blades 4 with primary blades 1.The knuckle α of primary blades 1
1(meeting liquid angle) makes impeller drag reduce, and makes primary blades 1 produce downward active force simultaneously, so this impeller forms the stronger feature of axial flow characteristic.
The application conditions of this utility model: impeller diameter 500 ~ 3000mm; Wheel speed n, 10<n<3000rpm; The reynolds number Re that impeller produces is middle high region; Be applicable to the mixing that concentration is homogeneous, the mixing that temperature is homogeneous, the suspension of immobilized particles is dissolved, anti-settling degradation.
