Description

Technical Field

[0001] This utility model relates to the field of aeration technology for air flotation machines, and in particular to an aeration device for a vortex air flotation machine. Background Technology

[0002] The aeration device in the vortex-type air flotation machine is a key component. It mainly introduces air into the wastewater through mechanical aeration, thereby generating a large number of microbubbles. These microbubbles combine with suspended particles, grease, and other pollutants in the wastewater, causing the pollutants to adhere to the bubbles and rise to the water surface with them, achieving solid-liquid separation and purifying the wastewater.

[0003] The aeration devices used in current air flotation machines typically introduce external gas directly into the aeration device, which can continuously provide sufficient oxygen to meet the oxygen requirements of microorganisms in the water. This helps aerobic microorganisms grow and metabolize, thereby efficiently decomposing pollutants such as organic matter and ammonia nitrogen in the water and improving the wastewater treatment effect.

[0004] Although introducing external gas directly into the aeration device can supplement oxygen, the external gas will carry dust, impurities, etc. After these substances enter the aeration device, they will wear down the internal components of the device, such as the impeller and air pump, shorten the service life of the equipment, and also affect the aeration effect and reduce the flotation efficiency. To solve the above problems, an aeration device for a vortex-type flotation machine is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an aeration device for a vortex air flotation machine, which aims to improve the problem that the existing technology cannot treat impurities in external gas.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1 , Figure 2 and Figure 6 An embodiment of this utility model is provided: an aeration device for a vortex air flotation machine, including a tube shell 1, an outer shell 2 fixedly connected to the end of the tube shell 1, a rotating component provided inside the outer shell 2, a filter air inlet component provided inside the end of the tube shell 1, a gas separation and distribution component provided inside the tube shell 1, and a gas stirring and dividing component rotatably connected inside the outer shell 2.

[0036] The air intake filter assembly includes an intake pipe 3, which is fixedly connected to the inner side of the end of the housing 1. An air pump 5 is fixedly connected to the inner side of the intake pipe 3. After the air pump 5 is started, outside air enters through the connecting pipe 6 under its suction force. The air intake filter assembly also includes a connecting pipe 6, which is fixedly connected to the input end of the air pump 5. A groove 21 is provided on the inner side of the connecting pipe 6. Multiple fixing rings 19 are provided on the inner side of the connecting pipe 6. A filter screen 22 is fixedly connected to the inner side of each of the multiple fixing rings 19. Two sliders 20 are fixedly connected to the outer side of each of the multiple fixing rings 19. The sliders 20 are all located inside the groove 21. Multiple fixing rings 19 are provided inside the connecting pipe 6, and a filter screen 22 is fixed to the inner side of each fixing ring 19. Since the slider 20 on the outside of the fixing ring 29 is set in the groove 21 on the inside of the connecting pipe 6, it not only facilitates the installation and removal of the filter screen 22, making it easy to clean and replace it, but also ensures that when air flows through these filter screens 22, the dust, impurities and other contaminants are intercepted by the filter screens, thus ensuring that the air entering the intake pipe 3 is clean.

[0037] Reference Figure 2 and Figure 3 The gas separation and distribution assembly includes multiple fixing rings 13, each fixedly connected to the inner side of the tube shell 1. Microporous disks 12 are fixedly connected to the inner sides of the fixing rings 13. When air enters the tube shell 1, it is divided into numerous fine airflows through the micropores on these microporous disks 12. Sealing rings 14 are fixedly connected to the sides of each microporous disk 12. The sealing rings 14 on the sides of the microporous disks 12 ensure that gas does not leak from the connection between the microporous disks 12 and the tube shell 1, allowing gas to flow out only through the micropores on the microporous disks 12, further ensuring the uniformity of gas distribution.

[0038] Reference Figure 1 , Figure 2 and Figure 4 The rotating assembly includes a drive motor 18, which is fixedly connected to the outside of the housing 2. Gear 16 and Gear 17 are rotatably connected to the inside of the housing 2, with Gear 16 meshing with the outside of the drive motor 18. Gear 17 is fixedly connected to the output end of the drive motor 18. When the drive motor 18 starts, it drives Gear 17 to rotate. Because Gear 17 meshes with Gear 16, the rotation of Gear 17 drives Gear 16 to rotate synchronously. A protective shell 4 is fixedly connected to the outside of the housing 2, surrounding the drive motor 18. The protective shell 4, fixed to the outside of the housing 2 and enclosing the drive motor 18, prevents external factors from damaging the drive motor 18 and ensures its stable operation.

[0039] Reference Figure 2 , Figure 3 and Figure 5 The gas mixing and dividing assembly includes a tube rod 7, which is fixedly connected to the side of gear 16. Two connecting blocks 8 are fixedly connected to the end of the tube rod 7, and multiple impellers 9 are fixedly connected to the outer sides of each connecting block 8. Multiple protrusions 10 are fixedly connected to both sides of each impeller 9. When the tube rod 7 rotates, the impellers 9 and protrusions 10 rotate at high speed, mixing and dividing the gas and surrounding liquid that are uniformly distributed after passing through the gas dividing and distributing assembly. This causes the gas to form smaller bubbles and mix thoroughly with the liquid. An auger blade 11 is fixedly connected to the outer side of the tube rod 7 and rotatably connected to the inner side of the tube shell 1. As the tube rod 7 rotates, the auger blade 11 can push the gas and liquid to flow axially within the tube shell 1, which helps the gas pass better through the microporous disk 12 and further promotes gas-liquid mixing. A positioning ring 15 is rotatably connected to the inner side of the end of the tube shell 1 and is fixedly connected to the outer side of the tube rod 7. The positioning ring 15 on the inner side of the end of the tube shell 1 is fixed to the outer side of the tube rod 7, which plays the role of positioning and supporting the tube rod 7, ensuring the stability of the rotation of the tube rod 7, and preventing it from shaking or deviating during rotation.

[0040] Working principle: First, start the air pump 5, which draws in outside air through the connecting pipe 6. The air flows inside the connecting pipe 6 and passes through the filter screen 22 inside multiple fixed rings 19. The filter screen 22 filters the air, removing impurities and ensuring that the air entering the device is clean. The filtered air enters the housing 1 through the air inlet pipe 3.

[0041] After the gas enters the casing 1, the drive motor 18 is started, driving gear 17 to rotate. Since gear 17 meshes with gear 16, gear 16 rotates. The tube rod 7, which is fixedly connected to gear 16, rotates accordingly. At the same time, the auger blade 11 on the outside of the tube rod 7 also rotates with the tube rod 7. When the auger blade 11 rotates, it not only propels the gas forward but also causes the gas to rotate. This rotating flow causes the gas to form vortices inside the casing 1, thereby achieving preliminary mixing and stirring of the gas itself, making the gas distribution from the inlet pipe 3 more uniform, and preparing for the subsequent uniform distribution and refinement of the gas by the gas separation and distribution assembly.

[0042] The air entering the casing 1 encounters the microporous disks 12 inside the multiple fixed rings 13 under the thrust of the air pump 5. The microporous disks 12 separate the air into multiple small airflows, allowing the air to be more evenly distributed inside the casing 1. Finally, the rotation of the multiple impellers 9 on the outside of the connecting block 8 at the end of the tube rod 7 causes the protrusions 10 on both sides of the impellers 9 to further stir and separate the gas and liquid during rotation, ensuring that the gas and liquid are fully mixed.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
