Description

Technical Field

[0001] The utility model relates to an integrated multi-stage oxygenation impeller, belonging to the technical field of oxygenation impellers. Background Art

[0002] Currently, commercially available aeration impellers rely on a drive motor to rotate the blades, pushing the water in the right direction. This pumps water, stirs it into the air, mixes the water and air, and increases the water's oxygen content. Existing aeration impellers typically utilize multiple sets of spiral, three-bladed impellers stacked coaxially in an upper and lower arrangement to enhance the oxygenation effect. Furthermore, stacking multiple impellers requires that the two adjacent layers of impellers be staggered to achieve the desired effect. This staggered stacking imposes very strict and precise angle requirements. However, the impellers are often stacked manually, making it difficult to achieve the precise angle requirements. Furthermore, the impellers are mounted on the output shaft of the drive motor, making it difficult to ensure secure installation. The impellers can easily rotate relative to the output shaft, resulting in deviations in the impeller's installation angle and poor stability. This results in limited oxygen content in the water and poor oxygenation performance. Furthermore, multiple impellers must be manufactured and assembled together, making the production and installation process complex. Utility Model Content

[0003] The purpose of the utility model is to address the shortcomings of the prior art and provide an integrated multi-stage oxygenation impeller in which the wheel body and the blades of the blade group are integrally formed.

[0013] Compared with the prior art, the utility model integrally forms the upper blades and the lower blades on the wheel body, ensuring the precision of the staggered setting of the upper blades and the lower blades, while ensuring that the fixation between the upper blades, the lower blades and the wheel body is stable and reliable, thereby increasing the oxygen content in the water and improving the oxygenation effect. The production and installation process is simple and cost-saving; the unequal thickness structure enables the upper blades and the lower blades to not only disturb the water to flow upward, but also, according to the Bernoulli principle, enable the inclined blades to have a certain self-priming ability.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-3 As shown, the integrated multi-stage aeration impeller includes a wheel body 1 and a multi-layered blade assembly 2 integrally formed on the outer circumference of the wheel body 1. Each layer of blade assembly 2 includes a plurality of blades, and the blades of two adjacent layers of blade assembly 2 are staggered. Each layer of blade assembly 2 includes two blades evenly distributed in an annular shape on the outer circumference of the wheel body 1. The blades of all blade assemblies 2 are inclined curved plates.

[0018] In the above technical solution: the blade group 2 is provided with two layers, the blade group 2 includes a plurality of upper blades 21 located in the upper layer and a plurality of lower blades 22 located in the lower layer, the upper blades 21 are provided with two pieces, and the lower blades 22 are also provided with two pieces. The two upper blades 21 and the two lower blades 22 are staggered and evenly arranged on the outer peripheral surface of the wheel body 1.

[0019] In the above technical solution: the blades of all blade groups 2 are of unequal thickness structure.

[0020] In the above technical solution: a motor mounting hole 11 is formed through the wheel body 1, and a hole anti-rotation portion is provided on the motor mounting hole 11. The wheel body is connected to the drive motor, and a shaft anti-rotation portion is correspondingly provided on the output shaft of the drive motor. The output shaft is inserted into the motor mounting hole 11, and the hole anti-rotation portion and the shaft anti-rotation portion cooperate to make the wheel body 1 rotate synchronously with the output shaft of the drive motor. The hole anti-rotation portion is specifically a hole anti-rotation plane 12, and the shaft anti-rotation portion is correspondingly a shaft anti-rotation plane. The hole anti-rotation plane 12 is aligned with the shaft anti-rotation plane, and then the output shaft is inserted into the motor mounting hole 11. The output shaft and the motor mounting hole 11 are directly installed using a straight-in type, eliminating the fasteners that are inserted horizontally on the wheel body 1 for installing the output shaft of the drive motor in the prior art, ensuring the smoothness of the outer peripheral surface of the wheel body 1, and avoiding the situation where the fasteners protruding from the outer peripheral surface of the wheel body 1 generate a negative pressure area during rotation and block water inflow, thereby increasing the water inflow.

[0021] In the above technical solution: a plurality of reinforcing ribs 3 are provided between the bottom of the blades of the blade group 2 and the wheel body 1 , and the reinforcing ribs 3 are integrally formed with the wheel body 1 .

[0022] When the driving motor drives the wheel body 1 to rotate, the lower blade 22 drives the water to flow upward. When the water reaches a certain height, the upper blade 21 pushes the water to flow upward again, completing the secondary pressurization. At the same time, the upper blade 21 and the lower blade 22 are both unequal thickness structures that conform to the Bernoulli principle. While the upper surface of the blade pushes the water, the low-pressure area on the lower surface of the blade generates a vacuum negative pressure area. The vacuum suction generated by the negative pressure greatly improves the self-priming ability of the overall structure. As the impeller rotates, more water is sucked in, disturbing more water and increasing the spray of water, which greatly improves the working efficiency of the impeller and improves the effect of increasing the oxygen content in the water.

[0023] Existing impellers usually have three spiral blades, but the two layers of three blades cannot be integrally formed with the wheel body 1, resulting in difficulty in demolding. Therefore, in the present invention, two upper blades 21 and two lower blades 22 are integrally formed on the wheel body 1, facilitating the production and demolding of the impeller. At the same time, the improvement and enhancement of the two structures, namely, the improvement of the self-priming ability by the unequal thickness structure of the blades and the increase of the water intake by the direct plug-in installation of the output shaft of the drive motor and the wheel body 1, make the impeller in the present invention have an excellent oxygenation effect. As a result, the present invention can achieve a very good oxygenation rate by only having two blades on each layer. That is, while ensuring the oxygenation effect, it saves materials and costs, and facilitates the production and demolding of the impeller.

[0024] The utility model integrally forms the upper blade 21 and the lower blade 22 on the wheel body 1, ensuring the precision of the staggered arrangement of the upper blade 21 and the lower blade 22, while ensuring that the fixation between the upper blade 21, the lower blade 22 and the wheel body 1 is stable and reliable, thereby increasing the oxygen content in the water and improving the oxygenation effect. The production and installation process is simple and cost-effective. The unequal thickness structure enables the upper blade 21 and the lower blade 22 to not only disturb the water to flow upward, but also to enable the inclined blade to have a certain self-priming ability according to the Bernoulli principle. The multi-layer structure can make the water splash higher and produce multi-layer water splashes when splashed into the air, making the water splashes higher and larger, better mixed with the air, and more efficiently achieving the purpose of aeration and increasing the oxygen content in the water. The upper blade 21 and the lower blade 22 are both provided with two pieces, which saves materials and costs while ensuring the oxygenation effect, and facilitates the production and demoulding of the impeller.

[0025] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should fall within the scope of protection of the present invention.
