Description

Technical Field

[0001] The utility model relates to the technical field of micro-aeration, in particular to a micro-aeration device for sewage treatment. Background Art

[0002] Micro-aeration devices are indispensable in wastewater treatment. They improve oxygen transfer efficiency. The tiny bubbles they produce have a large specific surface area, increasing dissolved oxygen content and prolonging their residence time, providing sufficient oxygen for microbial metabolism. They also enhance mixing, evenly distribute wastewater components, promote contact between microorganisms and pollutants, and improve treatment efficiency. They can also reduce energy consumption and costs. Special aeration methods are energy-efficient and highly efficient, with simple equipment structure and low maintenance costs. They also enable refined treatment, adapting to varying water quality and quantity, meeting specialized treatment requirements, and ensuring effluent quality meets standards. Therefore, micro-aeration devices for wastewater treatment are used to address this issue.

[0003] Traditional micro-aeration systems for sewage treatment typically consist of the following components. First, the main aeration unit, such as the aeration fan in forced aeration, provides power for gas transport. Second, the aeration head or aerator, most commonly a microporous aeration head, disperses the gas into tiny bubbles to increase the contact area between the gas and the sewage. Finally, there's an air delivery piping system, responsible for transporting the gas generated by the aeration fan to the aeration head. Furthermore, regulating devices, such as valves, are included to control gas flow and pressure to suit varying sewage treatment needs and operating conditions, ensuring stable and efficient operation of the micro-aeration system.

[0004] However, traditional micro-aeration devices for sewage treatment have some obvious limitations in actual operation. During the aeration process, they are unable to effectively diffuse the aerated oxygen evenly and widely to the surrounding area. This is because there are certain defects in its aeration method and structural design, resulting in less than ideal distribution of oxygen in the water, affecting the oxygen utilization efficiency and sewage treatment effect. At the same time, when faced with large-scale sewage volumes, the device will appear to be inadequate. Its treatment capacity and aeration effect are difficult to meet the needs of large-scale sewage, resulting in problems such as insufficient aeration and incomplete reaction, which restrict the overall efficiency and quality of sewage treatment. Therefore, a micro-aeration device for sewage treatment is proposed to solve the above problems. Utility Model Content

A cabinet 3 is fixedly connected to the top of the first hollow plate 2. The material of the cabinet 3 can be stainless steel. Stainless steel has good corrosion resistance and can be used for a long time in a sewage environment without being easily rusted or damaged. A float 1 is fixedly connected to the side wall of the first hollow plate 2. The float 1 uses high-density polyethylene (HDPE). HDPE has good buoyancy performance and low density, and can provide sufficient buoyancy to make the device float on the water surface. At the same time, it has chemical corrosion resistance and a certain mechanical strength, and can be used for a long time in a sewage environment. A second hollow plate 9 is fixedly connected to the inside of the cabinet 3. The material of the second hollow plate 9 can be fiberglass. Glass fiber reinforced plastic is a composite material with excellent corrosion resistance, high strength and good insulation properties. A blower 10 is fixedly connected to the side wall of the second hollow plate 9. The output end of the blower 10 is fixedly connected to a connecting pipe 11. One end of the connecting pipe 11 is fixedly connected to the top of the first hollow column 7. A rotating assembly is provided on the side wall of the first hollow plate 2. A switch assembly is provided on the side wall of the cabinet 3. The switch assembly is used to facilitate observation of the internal structure.

[0033] The rotating assembly includes a second motor 12, the side wall of the second motor 12 is fixedly connected to the cabinet 3, the output end of the second motor 12 is fixedly connected to the first bevel gear 13, the first bevel gear 13, the second bevel gear 14 and the third bevel gear 15 can be made of alloy steel, which has high strength and hardness and can withstand large torque and load.

The stirring blades will be impacted and subjected to friction from the water flow during operation. Stainless steel can ensure their long-term stable operation and better improve the aeration effect.

[0034] Specifically, when using the micro-aeration device for sewage treatment, the entire device is first directly and steadily pushed into the sewage. Because the first hollow plate 2 is hollow in design and the sidewall of the first hollow plate 2 is installed with a float 1, the entire device can be effectively and stably floated on the water surface, providing a good foundation for subsequent operations. Subsequently, by starting the second motor 12, its output end drives the first bevel gear 13 to rotate. At the same time, the rotation of the first bevel gear 13 will drive the second bevel gear 14 and the third bevel gear 15 that are meshed with it to rotate respectively. In addition, the first hollow column 7 is fixed inside the second bevel gear 14. When the second bevel gear 14 rotates, it drives the second stirring blade 17 to rotate. At the same time, although the third bevel gear 15 rotates inside the second hollow plate 9, it also wraps its interior around the outer wall of the first hollow column 7, thereby driving the first stirring blade 16 to rotate as well. In this way, the rotation trajectories of the second stirring blade 17 and the first stirring blade 16 show an effect of one forward rotation and one reverse rotation, which can more fully stir and mix the sewage. Subsequently, sufficient oxygen is generated by the blower 10 and then discharged into the interior of the first hollow column 7 through the connecting pipe 11. At the same time, an aerator 18 is fixed inside the first hollow column 7, which can disperse the oxygen, thereby producing an aeration effect, promoting sufficient contact between oxygen and sewage, and improving sewage treatment efficiency.

[0035] Reference Figure 1 and Figure 3The top of the cabinet 3 is fixedly connected to a top plate 5, and the top of the top plate 5 is fixedly connected to the first motor 4. The output end of the second bevel gear 14 is fixedly connected to a threaded rod 19. The threaded rod 19 can be made of stainless steel. Stainless steel has good strength and corrosion resistance. It can maintain stable performance in sewage environment and long-term operation, and prevent rust and deformation. One end of the threaded rod 19 is fixedly connected to a first connecting plate 22. The bottom of the first connecting plate 22 is fixedly connected to the top of the top plate 5. The first connecting plate 22 can be made of aluminum alloy to reduce weight and facilitate processing and connection. The outer wall of the threaded rod 19 is rotatably connected to a movable plate 20. The top of the movable plate 20 is rotatably connected to a third connecting plate 26. One end of the third connecting plate 26 is rotatably connected to the first rotating plate 6. The side wall of the first rotating plate 6 is fixedly connected to the second connecting plate 24.

The solar panel 23 is fixedly connected to the side wall of the second connecting plate 24. The frame of the solar panel 23 can be made of aluminum alloy to ensure strength and lightness.

[0036] Specifically, the output end of the first motor 4 starts to operate, driving the threaded rod 19 to rotate. At this time, one end of the threaded rod 19 rotates steadily inside the first connecting plate 22, and during its rotation, it drives the movable plate 20 connected thereto to move on the top of the top plate 5. In order to ensure that the movable plate 20 can move smoothly along the predetermined direction without deviation, a control function is exerted by the rotating wheel 21. As the movable plate 20 moves, it drives the third connecting plate 26 to rotate, and the rotation of the third connecting plate 26 drives the first rotating plate 6 to rotate. When the first rotating plate 6 moves, it can drive the solar panel 23 to rotate together, so that it can be adjusted in real time according to the position of the sun to maximize the reception of solar energy, provide sufficient energy support for the operation of the device or realize other functions related to solar energy utilization, and improve the energy utilization efficiency and operational stability of the entire system.

[0037] Reference Figure 1 The side wall of the cabinet 3 is provided with a switch assembly, which includes a door 25. The side wall of the door 25 can be made of acrylic plate. Acrylic plate has light weight and good transparency. The side wall of the door 25 is fixedly connected with a handle 8, and the handle 8 can be made of polyethylene (PE) plastic. PE plastic has the characteristics of light weight, low cost, good insulation and processing properties, and can be easily made into the shape of the handle 8. The side wall of the door 25 is rotatably connected to the inner wall of the cabinet 3. The hinges and other components of the rotating connection can be made of aluminum alloy. Aluminum alloy has the characteristics of high strength, good corrosion resistance and light weight.

[0038] Specifically, by pulling the handle 8, when a pulling force is applied to the handle 8, the handle 8 receives the force and transmits the force to the door 25, causing the door 25 to rotate about the connecting axis on the inner wall of the cabinet 3, thereby achieving the purpose of conveniently viewing the interior of the cabinet 3. This allows the operator to easily open the door 25 and intuitively understand the internal conditions of the cabinet 3 at any time. Whether it is checking the operating status of the equipment, checking the storage status of items, or performing daily maintenance and management, it becomes more convenient and efficient, providing convenient conditions for the use and maintenance of the micro-aeration device for sewage treatment.

[0039] Working principle: When using the micro-aeration device for sewage treatment, first directly push the entire device into the sewage. Since the first hollow plate 2 is hollow in design and the side wall of the first hollow plate 2 is installed with a float 1, the entire device can be effectively floated on the water surface. Then, the first bevel gear 13 is driven to rotate by the output end of the second motor 12. At the same time, the rotation of the first bevel gear 13 will drive the second bevel gear 14 and the third bevel gear 15 meshed therewith to rotate respectively, and the first hollow column 7 is fixed inside the second bevel gear 14. At the same time, the rotation of the second bevel gear 14 drives the second stirring blade 17 to rotate. At the same time, although the third bevel gear 15 rotates inside the second hollow plate 9, it also puts the inside on the outer wall of the first hollow column 7, which can drive the first stirring blade 16 to rotate together. In this way, the rotation trajectories of the second stirring blade 17 and the first stirring blade 16 are one forward and one reverse. Then, through the blower 10 Sufficient oxygen is generated and discharged into the interior of the first hollow column 7 through the connecting pipe 11. At the same time, an aerator 18 is fixed inside the first hollow column 7, which can disperse the oxygen to produce the effect of aeration. Next, the threaded rod 19 is driven to rotate by the output end of the first motor 4, and one end of the threaded rod 19 rotates inside the first connecting plate 22. At the same time, the rotation of the threaded rod 19 drives the movable plate 20 to move on the top of the top plate 5, and the movable plate 20 is controlled not to deviate from the direction by the rotating wheel 21. Next, the movement of the movable plate 20 drives the third connecting plate 26 to rotate, and then the rotation of the third connecting plate 26 drives the first rotating plate 6 to rotate. The movement of the first rotating plate 6 can drive the solar panel 23 to rotate together, so as to adjust according to the position of the sun. At the same time, the handle 8 can be pulled, and the handle 8 is driven by force to drive the door 25 to rotate on the inner wall of the cabinet 3, so that the internal situation can be easily viewed.
