Description

Technical Field

[0001] This invention belongs to the technical field of purification and treatment of domestic sewage and various industrial wastewater. Background Technology

[0002] In recent years, my country's urban sewage and industrial wastewater treatment capacity has developed rapidly, with many sewage treatment plants being built or about to be built across the country. A typical medium-sized sewage treatment plant produces approximately 20,000 tons of sludge daily (70%–80% moisture content). The harmless recycling of sewage is currently the main method for water pollution treatment. The core of this method is secondary sewage treatment, which primarily involves using aeration aerators to introduce large amounts of gas into the sewage tank. Current aeration devices mainly include microporous aerators, rotary disc aerators, inverted umbrella aerators, blower aerators, mechanical agitators, and jet aerators, but they generally suffer from low oxygenation capacity and utilization rate, uneven air distribution, frequent clogging or bursting, and are extremely difficult to repair and replace, resulting in even lower power efficiency. To date, the research and manufacturing processes for all aeration and oxygenation devices, both domestically and internationally, are primitive, simply using mechanical methods to deliver ordinary air into the water, allowing oxygen from the air to naturally mix into the water. Therefore, oxygen utilization and mechanical power efficiency are both very low. Furthermore, 70% to 80% of the energy consumption in wastewater treatment plants comes from aerators. However, design flaws have prevented further reductions in energy consumption. Based on the working principle of oxygen-enhancing aerators and the mass transfer principle of gases, modifying the corresponding structure to increase the power of the aerators or to increase the oxygen content of the gas introduced into the wastewater is the only effective way to improve wastewater treatment efficiency. Moreover, in the era of intelligent information technology, realizing the intelligent and green development of aerators has become an important direction of the new round of technological revolution.

[0003] The main components of air are nitrogen and oxygen. The molecules of these two gases exhibit different magnetic properties: oxygen molecules are paramagnetic, while nitrogen molecules are diamagnetic. In a magnetic field, paramagnetic substances move towards regions with higher magnetic field density, while diamagnetic substances move towards regions with lower magnetic field density. Based on this principle, a magnetized oxygen-enriching device has been proposed. Modifying the air inlet using a magnetized oxygen-enriching device to increase the oxygen content of the inhaled gas is one way to improve the efficiency of an aerator. For example, Chinese patent application CN 114920369 A proposes a series of magnetized oxygen-enriching devices for aerators. However, the oxygen-enriching effect of the proposed magnetized oxygen-enriching devices still needs further improvement. Summary of the Invention

[0004] To solve this problem, the present invention proposes a mobile magnetized oxygen-enriching blower aerator, which consists of a float 1, an adjustable propeller, an underwater oxygen sensing device system, an aeration disc 8, a retractable aeration pipe 10, a blower 11, and a gradient magnetized oxygen-enriching device. Several floats 1 are evenly arranged around the aerator in a circumferential direction and connected to the edge of the aerator's circular frame. A floating plate is provided on the aerator's circular frame, and several gradient magnetization oxygen enrichment devices are set in the center of the floating plate. The retractable aeration pipe 10 is set below the gradient magnetization oxygen enrichment devices. An adjustable propeller is mounted on the circular frame of the aerator to drive its movement. The gradient magnetization oxygen enrichment device has a cylindrical outer shell 12, with one end as the air inlet and the other end as the air outlet. Several vertebral magnetic poles 16 are arranged along its central axis. The vertebral magnetic poles 16 are connected in series by magnetic pole fixing columns 15. Both ends of the vertebral magnetic poles 16 are fixedly connected to the outer shell 12 by support columns connected to the outer shell 12. The gradient magnetic field is formed by the equidistant arrangement of multiple vertebral magnetic poles 16. The air outlet is provided with a trumpet-shaped diverter plate 17, which extends from the tail of the gradient magnetization oxygen enrichment device 12 and is connected to the concentrated oxygen collection pipe 19. The air outlet is also provided with a nitrogen outlet 18. The gradient magnetic field is characterized by a strong gradient in the middle and weak gradient at both ends. Taking each pair of vertebral magnetic poles 16 as a unit, the line connecting the gaps between adjacent magnetic poles is the Z-axis, and the midpoint of the line is the origin. The gradient magnetic field distribution between each gap is an arch symmetrical about the origin. The retractable aeration pipe 10 is connected to the aeration disc 8 at the bottom, and an oxygen sensing system 9 is installed on the aeration disc 8. During the aeration process, the aeration depth is adjusted by extending and retracting the retractable aeration pipe 10.

[0005] Preferably, the gradient magnetization oxygen enrichment device 12 has a total of 8 groups, with its air inlets facing 8 different directions respectively. The concentrated oxygen collection pipes 19 at the air outlet end are connected together. Air is introduced from the air inlet end through the exhaust fan 11 below the concentrated oxygen collection pipe 19 and introduced into the retractable aeration pipe 10.

[0006] Preferably, both the air inlet 13 and the nitrogen outlet 18 of the gradient magnetization oxygen enrichment device 12 are provided with breathable fine mesh.

[0007] Preferably, the oxygen sensing system 9 consists of an annular frame 21, a transverse guide rail 22, a transverse pulley 23, an oxygen sensor 24, a longitudinal pulley 25, and a longitudinal guide rail 26. The annular frame 21 is provided with two transverse guide rails 22, and two transverse pulleys 23 are respectively installed on the two transverse guide rails 22. The longitudinal guide rail 26 is fixedly installed between the two transverse pulleys 23. The longitudinal pulley 25 slides on the longitudinal guide rail 26, and the oxygen sensor 24 is installed on the longitudinal pulley 25.

[0008] Preferably, the aeration disc 8 adopts a hexagonal aeration disc structure. This shape facilitates better and more complete aeration.

[0009] Preferably, the adjustable propeller consists of a main support 28, a large propeller 4, and two small propellers 5. A cross-shaped support frame 27 is provided below the main support 28. The large propeller 4 is installed on the middle branch, and the two small propellers 5 are installed on the small branches on both sides. The middle part of the two small branches bends towards the middle branch, so that the two small propellers 5 are at a 45-degree angle to the large propeller.

[0010] Preferably, the aerator further includes a solar panel 2, which is mounted on a floating disc to provide auxiliary power for the adjustable propeller and the blower 11.

[0011] Preferably, the aerator further includes a signal receiver 3, which is mounted on the floating disc and is used to receive and send control signals to the adjustable propeller and the blower 11.

[0012] The beneficial effects of this invention are: The oxygen-enriched section on the water uses multiple gradient magnetization oxygen-enrichment devices, with the magnetic poles designed in a spine shape to increase the contact area between the air and the magnetic poles, thereby improving the oxygen separation degree.

[0013] Underwater oxygenation section: Employs telescopic aeration pipes, enabling a single unit to oxygenate multiple layers of water. It utilizes a six-outlet aeration disc, offering superior performance compared to other aeration discs. Additionally, it is equipped with two flexible propellers underwater; the larger and smaller propellers rotate individually or together to propel the translational movement of the system.

[0014] The entire machine is intelligent and energy-efficient: it utilizes solar-assisted power generation. An oxygen concentration sensor and its track are installed at the end of the telescopic pipe. The oxygen concentration sensor provides feedback on the oxygen content of the water area where the aeration port is located, controlling the next horizontal movement of the aerator or the raising and lowering of the aeration pipe. Simultaneously, it relays the dissolved oxygen status of the operating water area to the user's equipment, enabling remote control.

[0015] In summary, this product achieves energy conservation, high-efficiency oxygen enrichment, and a high degree of intelligence and automation, enabling a single machine to complete aeration operations in waters of different depths and covering the entire area. Attached Figure Description

[0017] Figure 2 This is an overall schematic diagram of a mobile magnetized oxygen-enriched blower aerator using solar energy as an auxiliary power source, as described in this embodiment. The aerator consists of a float 1, a solar panel 2, a signal receiver 3, adjustable propellers 4-5, an underwater oxygen sensing system 6-8, an aeration disc 9, a retractable aeration pipe 10, a blower 11, a gradient magnetized oxygen-enriching device 12, and a float 13. Several floats 1 are evenly arranged around the aerator and connected to the edge of the aerator's circular frame. A floating disc is provided on the aerator's circular frame, and several gradient magnetization oxygen enrichment devices are set in the center of the floating disc. A retractable aeration pipe 10 is set below the gradient magnetization oxygen enrichment device and connects the gradient magnetization oxygen enrichment device to the aeration disc 8 through the retractable aeration pipe 10. An adjustable propeller is mounted on the circular frame of the aerator to drive the aerator to move; a solar panel 2 and a signal receiver 3 are mounted on a floating disc. The solar panel 2 is used to provide auxiliary power for the adjustable propeller and the blower 11, and the signal receiver 3 is used to receive and send control signals to the adjustable propeller and the blower 11.

[0018] like Figure 3 and Figure 4 As shown, the gradient magnetization oxygen enrichment device 12 has a cylindrical outer shell 12, with one end as the air inlet and the other end as the air outlet. Several vertebral magnetic poles 16 are arranged along its central axis, connected in series by magnetic pole fixing columns 15. Both ends of the vertebral magnetic poles 16 are fixedly connected to the outer shell 12 by support columns connected to the outer shell 12. The multiple vertebral magnetic poles 16 are arranged at equal intervals to form a gradient magnetic field. A trumpet-shaped diverter 17 is provided at the air outlet, extending from the tail of the gradient magnetization oxygen enrichment device 12 and connected to a concentrated oxygen collection pipe 19. A nitrogen outlet 18 is also provided at the air outlet. The gradient magnetic field exhibits the characteristic of being strong in the middle and weak at both ends. Taking each pair of vertebral magnetic poles 16 as a unit, the line connecting the gaps between adjacent magnetic poles is the Z-axis, and the midpoint of the line is the origin. The gradient magnetic field distribution between each gap is an arch shape symmetrical about the origin (e.g., ...). Figure 1 (as shown) In this embodiment, the gradient magnetization oxygen enrichment device 12 is provided in 8 groups, with its air inlets facing 8 different directions. The concentrated oxygen collection pipes 19 at the air outlet are connected together. Air is introduced from the air inlet through the exhaust fan 11 below the concentrated oxygen collection pipe 19 and introduced into the retractable aeration pipe 10.

[0019] Due to the different magnetic properties of nitrogen and oxygen, nitrogen in the incoming air tends to move towards the pipe wall, while oxygen tends to move towards the magnetic pole. Oxygen adheres closely to the magnetic pole, while nitrogen approaches the pipe wall. Under the action of the trumpet-shaped diverter, the air is diverted. The oxygen-enriched air enters the exhaust fan 11 from the concentrated oxygen collection pipe 19, and is then transported into the retractable aeration pipe 10. Finally, it is introduced into the water through the aeration disc 8 for aeration. The high-concentration nitrogen is discharged through the nitrogen outlet 18 and returns to the atmosphere. In addition, to prevent dust and sand particles from entering this single-channel device and causing blockage, breathable fine mesh is installed at both the air inlet 13 and the nitrogen outlet 18.

[0020] like Figure 5 As shown, the retractable aeration pipe 10 is connected to the aeration disc 9 at the bottom, and an oxygen sensing system 8 is installed on the aeration disc 9. During the aeration process, the aeration depth is adjusted by extending and retracting the retractable aeration pipe 10, aerating the water body in a sequence from shallow to deep. The oxygen sensing system 8 moves up and down with the retractable aeration pipe 10, thereby detecting the oxygen content at different water levels, enabling targeted aeration of water bodies at different depths within the aeration range using a single machine.

[0021] The state of the retractable aeration pipe 10 not being extended is set as the initial state. The aerator starts working from the initial state, and the oxygen sensing system 8 starts detecting the oxygen content. When the dissolved oxygen content in the aerated water at the initial state depth reaches the standard, the controller controls the retractable aeration pipe 10 to extend a certain distance to continue aeration in the new depth of water until the oxygen content in the new depth of water reaches the requirement. Then the pipe is extended further. This process is repeated until the aeration pipe reaches its maximum extension length. This is the positive aeration process.

[0022] like Figure 6The oxygen sensing system 8 consists of an annular frame 21, a transverse guide rail 22, a transverse pulley 23, an oxygen sensor 24, a longitudinal pulley 25, a longitudinal guide rail 26, and a power supply cable 27. The annular frame 21 has two transverse guide rails 22, and two transverse pulleys 23 are respectively mounted on the two transverse guide rails 22. A longitudinal guide rail 26 is fixedly installed between the two transverse pulleys 23, and the longitudinal pulley 25 slides on the longitudinal guide rail 26. The oxygen sensor 24 is mounted on the longitudinal pulley 25. Through the nested structure of the longitudinal pulley 25 and the transverse pulley 23, the oxygen sensor 24 can more completely detect the dissolved oxygen content in the circular area of ​​water at the same height near the aeration port. The upper end of the cable 27 is connected to the bottom of the float 13, passes through the retractable aeration pipe 10, and the lower end is connected to the transverse pulley 23, providing power to the sensing device.

[0023] like Figure 7 As shown, in this embodiment, the aeration disc 9 adopts a hexagonal aeration disc structure. This shape facilitates better and more complete aeration.

[0024] like Figure 8 As shown, in this embodiment, the adjustable propeller consists of a main support 28, a large propeller 4, and two small propellers 5. A cross-shaped support frame 27 is located below the main support 28. The large propeller 4 is mounted on the middle branch, and the two small propellers 5 are mounted on the two side branches. The middle of the two side branches bends towards the middle branch, so that both small propellers 5 form a 45-degree angle with the large propeller. When the large propeller is started alone, the device achieves linear motion. The operation of the small propellers provides lateral thrust, and the simultaneous operation of the large and small propellers achieves curved motion. Thus, all the necessary operations for the basic water surface translation required by the device are essentially completed.

[0025] Once the dissolved oxygen content in the water reaches the standard, the controller controls the adjustable propeller to propel the water flow and move the aerator horizontally. The aeration pipe of the machine is fully extended in the new water area. The sensors continue to operate until the oxygen concentration in the deepest water reaches the standard. Then, the extension pipe retracts upwards a certain distance to aerate a shallower area until it returns to its initial state, completing the aeration of this vertical water volume. This is called the reverse aeration process. Subsequently, the controller controls the adjustable propeller to rotate, changing water areas for the forward aeration process. Through continuous alternating forward and reverse aeration processes, full coverage aeration of the entire water area is achieved.
