Description

Technical Field

[0001] The invention relates to the field of submersible aerators, in particular to a submersible aeration and stirring device. Background Art

[0002] A submersible aerator is a device used for aeration and oxygenation in the process of water treatment. The submersible motor drives the impeller. The extracted air and water pass through the high-speed operation of the impeller, are stirred and sheared to form dissolved water, and the water is pushed out to spread around. The rotation of the impeller shears the extracted air into fine tiny bubbles that merge with the water, so that the oxygen in the atmosphere is dissolved in the water, thereby achieving the purpose of aerating and oxygenating the water. The fine tiny bubbles have a large surface area and a slow rising speed, which can ensure sufficient mixing of water and oxygen. However, only by using the impeller to stir and cut the air, the size of the bubbles after the air cutting cannot be ensured, and the generation of dissolved water is unstable. Different water qualities will also affect the fusion of water and air. In addition, traditional submersible aerators can often only aerate and push flow in the same direction. The inability to control the push flow direction will lead to a decrease in the aeration and dissolved oxygen efficiency of the water. Summary of the invention

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. The following text is only used to describe an implementation method of a submersible aeration and stirring device of the present invention, and does not strictly limit the protection scope of the specific request of the present invention.

[0027] Example: Figure 1-Figure 6 As shown, a submersible aeration and stirring device comprises:

[0028] Box 3, such as Figure 1 As shown, an air inlet pipe 2 is installed on the upper side of the box body 3, and an air pump 6 is installed inside the box body 3. The air pump 6 is used to suck air into the air inlet pipe 2. A plurality of water inlet pipes 13 are arranged on the surface of the box body 3, and water enters the inside of the box body 3 through the water inlet pipes 13;

[0029] The aeration stirring component is placed inside the box 3. Figure 2 As shown, the aeration stirring assembly includes four groups of impellers 7, a rotating shaft 11, a rotating rod 8 and an aeration stirring motor 9. The four groups of impellers 7 are respectively installed in different directions of the rotating shaft 11. The aeration stirring motor 9 drives the rotating shaft 11 to rotate. The impeller 7 and the rotating shaft 11 are hollow structures. The air pump 6 pumps air into the rotating shaft 11 and the impeller 7. Figure 4 As shown, a plurality of air outlet holes 10 are evenly arranged on the upper and lower surfaces of the impeller 7, and the air outlet holes 10 can divide the air into small bubbles to oxygenate the water body, thereby forming dissolved air water;

[0030] The outlet pipe 4 is provided at the output end of the aeration and stirring assembly, and a plurality of outlet channels 14 are provided around the outlet pipe 4. Figure 6As shown, the water outlet channel 14 includes a water inlet 16 and a water outlet 15, and dissolved air water enters the water outlet channel 14 from the water inlet 16 and flows out from the water outlet 15, aerating and oxygenating water bodies in different directions;

[0031] Support seat 5, such as Figure 1 As shown, the water outlet pipe 4 is placed on the upper surface of the support base 5 , and the aeration stirring motor 9 is placed inside the support base 5 .

[0032] In an embodiment, Figure 3 As shown, one end of the intake pipe 2 is placed in the air, and a protective cover 1 is installed on the end of the intake pipe 2 placed in the air. The side of the protective cover 1 is a closed structure to prevent debris from the side from entering the intake pipe 2 and affecting the operation of the air pump 6. The interior of the protective cover 1 is a hollow structure connected to the intake pipe 2. The top surface of the protective cover 1 is a dust filter 12. Air enters the intake pipe 2 through the dust filter 12 and the protective cover 1 to prevent the intake pipe 2 from being contaminated by dust and causing device failure.

[0033] In an embodiment, Figure 1 As shown, the water inlet pipe 13 is arranged on the upper surface of the box body 3, and the water can flow into the box body 3 under the action of gravity. A barrier net 22 is attached to the surface of the water inlet pipe 13, and the barrier net 22 is used to block large impurities in the water body to prevent large impurities from entering the box body 3 and affecting the operation of the aeration stirring assembly.

[0034] In an embodiment, Figure 5 As shown, a gas-liquid mixing chamber 20 is formed between the box body 3 and the aeration stirring assembly, and the output end of the water inlet pipe 13 is facing the upper surface of the impeller 7. The tiny bubbles ejected from the air holes 10 on the upper surface of the impeller 7 are mixed with the water in the gas-liquid mixing chamber 20, and dissolved air water is formed after the impeller 7 rotates and stirs at high speed. The tiny bubbles ejected from the air holes 10 on the lower surface of the impeller 7 are not only used to further mix the water flowing out of the gas-liquid mixing chamber 20, but the tiny bubbles ejected from the air holes 10 on the lower surface of the impeller 7 also provide power for the dissolved air water to be ejected from the water outlet pipe 4, so that the dissolved air water can be ejected farther and the stirring and oxygenating effect on the water body is better.

[0035] In an embodiment, Figure 6 As shown, the spray direction of the water outlet channel 14 is obliquely downward. The obliquely downward spraying water outlet channel 14 allows the sprayed dissolved air water to stir the sludge at the bottom of the pool, and the sediment at the bottom of the pool can be effectively stirred into the water body and suspended, thereby improving the efficiency and effect of aeration and oxygenation.

[0036] In an embodiment, Figure 1As shown, a dissolved oxygen sensor 21 is installed on the surface of the box body 3. The dissolved oxygen sensor 21 is used to measure the oxygen content in the water body. A preset value of the oxygen content is set in the dissolved oxygen sensor 21. When the oxygen content of the water body reaches the preset value, the air pump 6 is turned off. When the air pump 6 is turned off, the aeration stirring motor 9 can drive the four sets of impellers 7 to rotate continuously, so as to achieve the purpose of stirring the water body without oxygenating it.

[0037] In an embodiment, Figure 6 As shown, a guide plate 18 is installed on the lower surface of the water outlet channel 14, and a guide plate rotating motor 17 is arranged at one end of the guide plate 18. The guide plate 18 is installed on the output end of the guide plate rotating motor 17. The guide plate rotating motor 17 can drive the guide plate 18 to rotate. The larger the angle between the guide plate 18 and the lower surface of the water outlet channel 14, the smaller the space between the guide plate 18 and the upper surface of the water outlet channel 14, and the longer the injection distance of the dissolved air water. The rotation angle of the guide plate 18 is different, and the direction in which the guide plate 18 guides the dissolved air water injection is also different. The rotation of the guide plate 18 realizes aeration and oxygenation of the water body in different directions and at different distances, thereby improving the efficiency and effect of aeration and oxygenation of the water body.

[0038] In an embodiment, Figure 6 As shown, a water-blocking cover 19 is installed outside the guide plate rotating motor 17 , and the water-blocking cover 19 is used to prevent dissolved air and water from affecting the operation of the guide plate rotating motor 17 .

[0039] When the present invention is in use, the air pump 6 sucks air into the air inlet pipe 2, and the water enters the gas-liquid mixing chamber 20 through the water inlet pipe 13. The air is cut into tiny bubbles through the air holes 10 on the upper and lower surfaces of the impeller 7 and enters the gas-liquid mixing chamber 20. The tiny bubbles and the water are fused into dissolved air water through the rotation and stirring of the impeller 7 and flow into the water outlet channel 14. The dissolved air water diffuses in a circular direction. The guide plate 18 in the water outlet channel 14 is initially attached to the lower surface of the water outlet channel 14. When the sludge at the bottom of the pool is fully stirred into the water, After suspension, the direction of the guide plate 18 is changed so that the dissolved air water is sprayed in different directions of the water body at the water outlet 15. When the dissolved oxygen sensor 21 detects that the oxygen content in the water body reaches a preset value, the water pump is turned off. While the air pump 6 is turned off, the aeration and stirring motor 9 can drive the four sets of impellers 7 to rotate continuously, so as to achieve the purpose of stirring the water body without oxygenating. The submersible aeration and stirring device disclosed in the present invention ensures the air crushing effect, the dissolved air water generation efficiency, and performs multi-directional aeration and oxygenation of the water body, thereby improving the efficiency and effect of aeration and oxygenation of the water body.
