Description

Technical Field

[0001] This utility model relates to the field of oxygenation equipment technology, specifically to an oxygenator impeller. Background Technology

[0002] Based on existing aerator impellers, such as the one described in announcement number CN102032209B, the impeller and the water surface are in surface-to-surface contact when the impeller rotates. This can only promote the water flow from bottom to top. Because the water flow is concentrated upward, the contact area between the water and the air during the upward flow is small, and the aeration effect needs to be improved. Utility Model Content

[0003] The purpose of this invention is to provide an aerator impeller to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an aerator impeller, including an inner ring, a support plate in the middle of the inner ring, and blades on the outer wall of the inner ring; the blades are distributed with a plurality of through holes of the same structure; wherein, when the support plate is parallel to the water surface, the central axis of the through hole forms an angle with the water surface, and the angle is an acute angle.

[0005] As a preferred technical solution of this utility model: the cross-section of the through hole facing the water surface is circular, and the cross-section of the through hole away from the water surface is elliptical.

[0006] As a preferred technical solution of this utility model: the side of the support plate facing the water surface is further provided with a first reinforcing rib and a second reinforcing rib; wherein, the number of the first reinforcing rib and the second reinforcing rib is multiple.

[0007] As a preferred technical solution of this utility model: the end of the blade away from the inner ring is connected to the outer ring.

[0008] As a preferred technical solution of this utility model: one end of the blade extends to the left side of the outer ring to form a first extension portion, and the other end of the blade extends to the right side of the outer ring to form a second extension portion.

[0009] As a preferred technical solution of this utility model, the extension length of the first extension is less than the extension length of the second extension.

[0010] As a preferred technical solution of this utility model: a wavy groove is also provided on the end face of the first extension.

[0011] The beneficial effects of this utility model by adopting the above technical solution are as follows: Since the blade is provided with a through hole, and when the support plate is parallel to the water surface, the central axis of the through hole forms an angle with the water surface, and the angle is an acute angle; therefore, when the blade causes the water to flow upward, the through hole can disperse the water flow. Since the water flow is dispersed during the flow, the contact area between the water flow and the air can be expanded, thereby improving the oxygenation effect of the aerator; at the same time, when the impeller rotates, the through hole can also cause the water flow to generate bubbles, so as to further improve the oxygenation effect of the equipment.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0018] Please see Figure 1-4 An embodiment of this utility model provides an aerator impeller, including an inner ring 5, a support plate 1 in the middle of the inner ring 5, and blades 3 on the outer wall of the inner ring 5; the blades 3 are distributed with a plurality of through holes 4 with the same structure; wherein, when the support plate 1 is parallel to the water surface, the central axis of the through hole 4 forms an angle with the water surface, and the angle is an acute angle.

[0019] In summary, since the blade 3 has a through hole 4, and when the support plate 1 is parallel to the water surface, the central axis of the through hole 4 forms an angle with the water surface, and this angle is acute; therefore, when the blade 3 causes the water to flow upward, the through hole 4 can disperse the water flow. Since the water flow is dispersed during the flow, the contact area between the water flow and the air can be increased, thereby improving the oxygenation effect of the aerator; at the same time, when the impeller rotates, the through hole 4 can also cause the water flow to generate bubbles, further improving the oxygenation effect of the equipment.

[0020] Based on this, by optimizing the structure of the impeller, the oxygenation effect can be improved while also reducing the power consumption of the equipment.

[0021] Furthermore, since the cross-section of the through hole 4 facing the water surface is circular, and the cross-section of the through hole 4 away from the water surface is elliptical, when the impeller rotates, the water flow enters from the elliptical side and then flows out from the circular side, which has a converging effect on the water flow. As the water flows obliquely upward, it can increase the height of the water flow upward, thus further increasing the contact area between the device and the air.

[0022] In addition, the support plate 1 is provided with a first reinforcing rib 6 and a second reinforcing rib 7 on the side facing the water surface; wherein there are multiple first reinforcing ribs 6 and second reinforcing ribs 7, so that the impeller has sufficient structural strength to extend its service life.

[0023] Based on the above scheme, since the end of the blade 3 furthest from the inner ring 5 is connected to the outer ring 2, the outer ring 2 can be used to enhance the structural strength of the blade 3, preventing deformation or twisting of the blade 3 due to water flow resistance when the impeller rotates. Because the blade 3 maintains a stable and reliable shape during rotation, the contact area between the water flow and air can be further increased, thereby improving the oxygenation effect of the equipment.

[0024] Meanwhile, one end of the blade 3 extends to the left side of the outer ring 2 to form a first extension 9, and the other end of the blade 3 extends to the right side of the outer ring 2 to form a second extension 10. Furthermore, the extension length of the first extension 9 is less than the extension length of the second extension 10; specifically, the extension length of the second extension 10 is twice the extension length of the first extension 9. Therefore, this ensures that the impeller is in full contact with the water, and also allows the impeller to increase the height of the upward flow of the water, thereby increasing the contact area between the water and the air.

[0025] In addition, in order to reduce the resistance when the impeller rotates, a wavy groove 8 is provided on the end face of the first extension 9.

[0026] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
