Description

Technical Field

[0001] The utility model relates to the technical field of blades, in particular to an axial flow blade with a wing shape. Background Art

[0002] When stirring low-viscosity and medium-viscosity materials, an agitator is usually used, and the materials are fully stirred by the agitator blades. When the axial flow blades are enlarged, a large water stress is usually generated in the pool body. During the stirring process, a vortex is generated under the blades to increase the radial force of the blades, causing the blades to shake when rotating, and the shaft of the agitator also shakes, which intensifies the shaking. Long-term shaking can easily cause the blades to fall off or the shaft to bend, and then cause the motor connected to the blades to shake, affecting the stirring effect of the entire agitator. The shaking of the motor during operation will reduce the service life of the motor. In order to reduce the shaking of the blades, a flow stabilizer is provided on the blades. For the existing blades with flow stabilizers, the flow stabilizer is provided in the middle of the blades, and the shaking of the blades cannot be effectively eliminated during the stirring process.

[0003] For example, a new type of axial flow blade with publication number CN204973761U includes a blade, which is composed of a hub, a long blade and a short blade. The long blade and the short blade are welded to the hub, and the long blade is fixedly installed under the short blade by bolts; a stirring shaft is installed at the bottom of the blade, and the stirring shaft is connected to a coupling in the frame, and the coupling is connected to the output shaft of the motor reducer. Compared with the prior art, the beneficial effect achieved by the utility model is that the blade can use very little energy to generate axial vortexes to achieve the purpose of uniform stirring. The blade is designed based on the principle of fluid mechanics, and achieves energy saving by increasing the flow rate and reducing turbulence and shear. The axial flow blade converts the available energy into pure axial flow to the greatest extent, and no flow turbulence occurs on the blade.

[0004] The above technical solution has the problem that the shaking of the blades cannot be effectively eliminated during the stirring process.

[0005] Therefore, it is necessary to invent a wing-shaped axial flow blade to solve the above problems. Utility Model Content
