Description

Technical Field

[0001] This utility model relates to an impeller used in an aerator, belonging to the field of aerator technology. Background Technology

[0002] The power unit of an impeller-type aerator drives an impeller submerged in water, causing it to rotate at high speed and pump water out of the water and into the air. When the water sprayed into the air comes into contact with oxygen in the air, the oxygen-deficient water dissolves the oxygen in the air, thus producing oxygen in the aquaculture pond. Currently, commonly used impellers consist of a disc and blades. As the disc rotates, the blades push the water outward to create waves, thereby increasing the contact between oxygen in the air and the water. However, although the impeller of this aerator moves a large amount of water, the contact time between the water and air is short, and the actual amount of air that can enter the water is limited, resulting in poor oxygenation effect.

[0003] To address the aforementioned shortcomings, existing technologies have employed inverted conical structures for the impeller and blades. While this improves surge and oxygenation, the outer edges of the blades are in direct contact with the water. During rotation, water flows out and then replenishes itself, causing significant impeller swaying, easy deformation leading to unstable water spray, and limited water lift. Additionally, floating vegetation easily gets caught on the blades, causing impeller vibration and preventing the creation of water spray. Ultimately, this results in low oxygen levels between the water and air, making the oxygenation effect still less than ideal. Utility Model Content

[0017] Figure 2 is a schematic diagram of the three-dimensional structure of the utility model stacked and placed. DETAILED DESCRIPTION

[0018] The utility model is further described below in combination with the drawings and specific embodiments.

[0019] As shown in Figure 1 , 2 , a kind of impeller applied to aerator, including wheel disc 1 and several blades 2, still include inner ring 3 and outer ring 4, inner ring 3 and outer ring 4 are located at the inside and outside of blade 2 respectively.Blade 2 upper and lower ends all protrude from the upper and lower ends of inner ring 3 and outer ring 4.Blade 2 and inner ring 3, outer ring 4 form splash channel 5 between.Through being arranged between inner ring 3 and outer ring 4 and forming splash channel 5, water can be guided from the bottom end of blade 2 to the upper end of blade 2, so that water always forms surge and splash between blade 2, inner ring 3 and outer ring 4, so that impeller shakes little, not easy to be deformed, water splash is more stable;Meanwhile, the water that is hit by blade 2 contacts outer ring 4 and is bounced back by outer ring 4, prevent water from flowing out and hitting floating ball, more water is agitated by blade 2 in splash channel 5 and splashes to sky to form water splash, the lift of water is increased by the shielding of outer ring 4, so that water splash is higher and more full, without gap;In addition, outer ring 4 also shields floating grass, prevent floating grass from hooking on blade 2, guarantee the stability of impeller rotation, guarantee the stability of water splash.Through splash channel 5, the water splash that aerator hits is big, high and divergent, so that water splash is better contacted and mixed with oxygen in air, and then effectively improve the oxygenation effect.

[0020] In the above technical solution, a plurality of splash holes 6 are formed in the blade 2, and the water entering the splash channel 5 can pass through the blade 2 through the splash holes 6 and flow in the splash channel 5. When the blade 2 rotates, a part of the water flows from the splash hole 6 of the blade 2 to the next blade 2, and is further pushed by the next blade 2 and cut by the splash hole 6, thereby further increasing the size, height and divergence of the water splash, and further improving the contact and mixing of the water splash with the oxygen in the air to increase the oxygen content in the water.

[0021] In the above technical solution, the blade 2 includes a large piece 21 in contact with the inner ring 3 and a small piece 22 in contact with the outer ring 4, the small piece 22 is formed by bending the end face of the large piece 21, and the splash hole 6 is formed in the large piece 21. When the water contacts the rotating small piece 22, the small piece 22 does not hit the water out of the splash channel 5, but hits the water forward, so that the water enters the splash channel 5 again and is agitated by the blade 2 to form water splash. The blade 2 with the bending structure changes the shape of the splash channel 5, and also increases the size, height and divergence of the water splash, thereby effectively improving the oxygenation effect.

[0022] In the above technical solution, the bottom end of the blade 2 is a flat surface 23, and the top end of the blade 2 is provided with an inclined surface 24 gradually increasing from low to high from inside to outside, so that the impeller can be stacked and placed. Figure 2As shown, the bottom surface of the outer ring 4 of the upper impeller is in contact with the highest part of the inclined surface 24 of the lower impeller when stacked, and the adjacent two impellers will not be stuck up and down. Meanwhile, the inner ring 3 is also provided with a displacement slot 31 for allowing the displacement of the blade 2 of the upper impeller after stacking to prevent interference. The inclined surface 24 enables the adjacent two impellers to be stacked and placed more stably, facilitating packaging and transportation. Specifically, the blades of the adjacent two impellers are placed staggered when stacked. The inclined surface 24 is also provided with an arc-shaped slot or a sawtooth slot.

[0023] In the above technical solution, six blades 2 are uniformly arranged between the inner ring 3 and the outer ring 4, and the inner ring 3 and the outer ring 4 are vertically parallel. Of course, the inner ring 3 and the outer ring 4 can be arranged to have a small distance between the lower ends and a large distance between the upper ends, and the overall cross section is in the shape of "V", so as to ensure that the water enters from the bottom end of the blade 2, and at the same time, the water splash is large, high and divergent, and the required motor current can be reduced. In addition, a plurality of blades 2 can be uniformly arranged on the outer circumferential surface of the outer ring 4.

[0024] In the above technical solution, the bottom of the wheel disc 1 is connected with the inner ring 3 through a plurality of uniformly arranged reinforcing ribs, which improves the connection stability between the wheel disc 1 and the inner ring 3, and further reduces the shaking of the impeller.

[0025] The blade 2 is arranged between the inner ring 3 and the outer ring 4, and a splash passage 5 is formed, so that the water always forms a surge and splash between the blade 2, the inner ring 3 and the outer ring 4, which makes the impeller shake less, not easy to deform, and the water splash is more stable. At the same time, the water splashed by the blade 2 contacts the outer ring 4 and is bounced back by the outer ring 4, preventing the water from flowing out and hitting the floating ball. More water is splashed by the blade 2 in the splash passage 5 to form a water splash in the sky, and the water lift is increased by the shielding of the outer ring 4, making the water splash higher and fuller without gaps, thereby effectively improving the oxygenation effect. In addition, the outer ring 4 also shields the floating grass, preventing the floating grass from being hooked on the blade 2, ensuring the stable rotation of the impeller and the stability of the water splash. The blade 2 includes a large piece body 21, and the end surface of the large piece body 21 is bent to form a small piece body 22. When the water contacts the rotating small piece body 22, the small piece body 22 will not splash the water out of the splash passage 5, but will splash the water forward, so that the water enters the splash passage 5 again. More water is splashed by the blade 2 in the splash passage 5 to form a water splash, increasing the height and fullness of the water splash, thereby effectively improving the oxygenation effect. By arranging the splash passage 5, the splash hole 6 and the small piece body 22, the oxygenation machine splashes water that is large, high and divergent, so that the water splash better contacts and mixes with the oxygen in the air, thereby effectively improving the oxygenation effect. The inclined surface 24 at the top end of the blade 2 enables the adjacent two impellers to be stacked and placed more stably, facilitating packaging and transportation.
