Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to an automatic lifting aeration system. Background Technology

[0002] In wastewater treatment, aeration systems are a common and crucial piece of equipment, playing a vital role in oxygen supply, mass transfer, stirring, and mixing. However, traditional aeration systems suffer from problems such as susceptibility to clogging, difficult maintenance, and inconvenient lifting. Due to their complex design, clogging or malfunctions in aeration systems typically require a water outage for repairs, emptying the water tank before resuming operation.

Obviously, the described embodiments are only some, not all, of the embodiments of this invention.

[0027] Figure 1 This is a schematic diagram of the automatic lifting aeration system provided by the present invention; Figure 2 yes Figure 1 Enlarged view of point A in the image.

[0028] Reference Figure 1 and Figure 2 The automatic lifting aeration system provided in this embodiment of the invention includes a lifting rod 200, an air duct 300, an aeration pipe 500, and a connecting assembly 600. The lifting rod 200 is vertically mounted on the side wall of a water tank 900; the air duct 300 is located in the middle of the water tank 900 and has a first opening at its bottom; the aeration pipe 500 is located at the bottom of the water tank 900 and has a second opening at one end, and is magnetically connected to the lifting rod 200; the connecting assembly 600 is located between the first opening and the second opening; the connecting assembly 600 is used to switch between a first state and a second state; in the first state, the air duct 300 and the aeration pipe 500 are connected; in the second state, the air duct 300 and the aeration pipe 500 are separated.

[0029] In the above structure, the air duct 300 is responsible for delivering air to the aeration pipe 500. The aeration pipe 500 is responsible for dispersing the air into the water tank 900 to achieve aeration. When the aeration pipe 500 moves to a specific position and connects to the first opening of the air duct 300 through the connecting component 600, air can enter the aeration pipe 500 and be released into the water tank 900. The connecting component 600 is a key part of the automatic lifting aeration system, which can switch between a first state and a second state. In the first state, the connecting component 600 connects the air duct 300 and the aeration pipe 500, allowing air to flow from the air duct 300 through the first opening into the aeration pipe 500, completing the aeration process. In the second state, the connecting component 600 disconnects the air duct 300 and the aeration pipe 500, cutting off the connection and stopping aeration. The lifting rod 200 can be raised and lowered as needed, thereby driving the magnetically connected aeration pipe 500 to move up and down.

[0030] When aeration is required, the lifting rod 200 moves the aeration pipe 500 downwards, thereby connecting the air duct 300 and the aeration pipe 500 via the connecting assembly 600. When maintenance is needed on the aeration pipe 500, it can be lifted using the lifting rod 200, separating it from the air duct 300 and allowing it to be raised outside the water tank 900 for repairs. The entire process does not require draining the water from the water tank 900, significantly reducing workload, and it does not require shutting down the wastewater treatment plant, avoiding unnecessary economic losses caused by shutdown.

[0031] In some possible embodiments, sensors and control systems can be introduced to automatically adjust the position and aeration intensity of the aeration pipes 500 based on water quality parameters (such as dissolved oxygen and turbidity) in the pool 900, achieving intelligent aeration control. Alternatively, multiple lifting rods 200 and aeration pipes 500 can be set up for independent aeration control in different areas of the pool 900 to meet the needs of complex water treatment. Specifically, the air duct 300 includes a vertical pipe and a horizontal pipe, with the horizontal pipe horizontally connected to the bottom end of the vertical pipe. The horizontal pipe has two first openings. There are two aeration pipes 500, each connected to one of the two first openings. Each aeration pipe 500 is equipped with a corresponding lifting rod 200, and each lifting rod 200 can independently control the raising and lowering of its corresponding aeration pipe 500. Of course, the number of aeration pipes 500 is not limited to two; it can be three, four, etc., and can be designed according to actual needs.

[0032] To improve aeration efficiency, the design and arrangement of the aeration pipes 500 can be optimized to enhance the uniformity of air dispersion in the water tank 900. Specifically, increasing the surface area of ​​the aeration pipes 500 increases the contact area with the water, thereby improving air transfer efficiency. Secondly, the aeration holes on the aeration pipes 500 can be micropores. This design generates smaller bubbles, increasing their residence time and surface area in the water, which is beneficial for oxygen dissolution and transfer. For the material of the aeration pipes 500, corrosion-resistant materials can be selected. To address the corrosiveness of the water, selecting corrosion-resistant and wear-resistant materials ensures the stability of the aeration pipes 500 and extends their lifespan. When arranging the aeration pipes 500, their position and number should be rationally arranged according to the shape and size of the water tank 900 and the aeration requirements to ensure uniform aeration, avoid dead zones, and ensure an appropriate installation depth. The installation depth of the aeration pipes 500 should be adjusted according to the actual situation to avoid insufficient aeration due to excessive depth or inadequate bubble dispersion due to insufficient depth.

[0033] Reference Figure 2 In some embodiments of the present invention, the connecting component 600 includes a first connecting component 610 and a second connecting component 620. The first connecting component 610 is disposed in a second opening, and the second connecting component 620 is disposed in a first opening. The first connecting component 610 and the second connecting component 620 are magnetically connected. The magnetic force between the first connecting component 610 and the second connecting component 620 is less than the magnetic force between the lifting rod 200 and the aeration pipe 500.

[0034] Specifically, the first connecting component 610 is fixedly installed at the second opening of the aeration pipe 500, while the second connecting component 620 is fixedly installed at the first opening of the air duct 300. When maintenance is required on the aeration pipe 500, the lifting rod 200 is lowered and magnetically connected to the aeration pipe 500. Then, the lifting rod 200 is raised. Since the magnetic force between the lifting rod 200 and the aeration pipe 500 is greater than the magnetic force between the first connecting component 610 and the second connecting component 620, the first connecting component 610 and the second connecting component 620 will disconnect as the lifting rod 200 rises, thereby allowing the aeration pipe 500 to be lifted for maintenance. After the aeration pipe 500 is maintained, it can be lowered using the lifting rod 200, aligning the first connecting component 610 and the second connecting component 620. Under the influence of magnetic force, they reconnect, reconnecting the aeration pipe 500 and the air duct 300, and resuming aeration operation. The entire process does not require draining the water from pool 900, which greatly facilitates maintenance by maintenance personnel and does not affect the normal operation of other aeration pipes 500.

[0035] Figure 3 A schematic diagram illustrating the structure of the connection components of the automatic lifting aeration system provided in an embodiment of the present invention during connection is shown.

[0036] Figure 4 A schematic diagram illustrating the structure of the connecting components of the automatic lifting aeration system provided in an embodiment of the present invention when separated is shown.

[0037] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the first connecting component 610 includes a first housing 611, which is connected to the second opening. A first magnetic baffle 612 is rotatably disposed inside the first housing 611. A first stop block 613 is disposed on the top inner wall of the first housing 611, and a first magnetic strip 614 is disposed on the bottom inner wall of the first housing 611. The first stop block 613 and the first magnetic strip 614 are offset, and the first magnetic baffle 612 is located between the first stop block 613 and the first magnetic strip 614. The second connecting component 620 includes a second housing 621, which is connected to the first opening. A second magnetic baffle 622 is rotatably disposed inside the second housing 621. A second stop block 623 is disposed on the top inner wall of the second housing 621, and a second magnetic strip 624 is disposed on the bottom inner wall of the second housing 621. The second stop block 623 and the second magnetic strip 624 are offset, and the second magnetic baffle 622 is located between the second stop block 623 and the second magnetic strip 624.

[0038] Specifically, the first connecting component 610 and the second connecting component 620 have basically the same structure, the difference being that when the first magnetic baffle 612 and the second magnetic baffle 622 attract each other, the first magnetic baffle 612 rotates counterclockwise and the second magnetic baffle 622 rotates clockwise. The first magnetic baffle 612 and the second magnetic baffle 622 can rotate vertically. When the first magnetic baffle 612 and the second magnetic baffle 622 rotate to the vertical direction, they respectively block the first housing 611 and the second housing 621, preventing water from the pool 900 from entering the aeration pipe 500. When the first magnetic baffle 612 and the second magnetic baffle 622 are magnetically connected, they are in a horizontal state, thus connecting the air pipe 300 to the aeration pipe 500, thereby achieving the aeration function. The cross surfaces of the first housing 611 and the second housing 621 are circular, and the first magnetic baffle 612 and the second magnetic baffle 622 are also circular. This allows the first magnetic baffle 612 and the second magnetic baffle 622 to rotate smoothly and also to block the first housing 611 and the second housing 621.

[0039] Furthermore, the first magnetic strip 614 is vertically fixedly installed on the bottom of the inner wall of the first housing 611, with its top end being the S pole. The first magnetic baffle 612, when in a vertical state, has its bottom end as the N pole. Through the principle of attraction between opposite poles, the first magnetic baffle 612 remains vertical, thus sealing the first housing 611. Additionally, when the first magnetic baffle 612 is in a vertical state, its top end abuts against the first stop block 613. Specifically, the first magnetic strip 614 is located on the left side of the first magnetic baffle 612, while the first stop block 613 is located on the right side. The first magnetic strip 614 and the first stop block 613 limit the movement of the first magnetic baffle 612, preventing it from rotating under water pressure and allowing water to enter the aeration pipe 500. In some possible embodiments, in order to ensure the sealing of the first magnetic baffle 612 to the first housing 611, sealing rings can be provided on both sides of the first magnetic baffle 612.

[0040] Furthermore, the second magnetic strip 624 is vertically fixedly installed on the bottom inner wall of the second housing 621, with its top end being the N pole. The second magnetic baffle 622, when in a vertical state, has its bottom end as the S pole. Through the principle of attraction between opposite poles, the second magnetic baffle 622 remains vertical, thus sealing the second housing 621. Additionally, when the second magnetic baffle 622 is vertical, its top end abuts against the second stop block 623. Specifically, the second magnetic strip 624 is located to the right of the first magnetic baffle 612, while the second stop block 623 is located to the left of the second magnetic baffle 622. The second magnetic strip 624 and the second stop block 623 limit the movement of the second magnetic baffle 622, preventing it from rotating under water pressure and allowing water to enter the aeration pipe 500. In some possible embodiments, in order to ensure the sealing of the second magnetic baffle 622 to the second housing 621, sealing rings can be provided on both sides of the second magnetic baffle 622.

[0041] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the magnetic force between the first magnetic baffle 612 and the second magnetic baffle 622 is greater than the magnetic force between the first magnetic baffle 612 and the first magnetic strip 614; the magnetic force between the first magnetic baffle 612 and the second magnetic baffle 622 is greater than the magnetic force between the second magnetic baffle 622 and the second magnetic strip 624.

[0042] In the above structure, when it is necessary to connect the aeration pipe 500 to the air duct 300, the first connecting component 610 is brought close to the second connecting component 620. Since the magnetic force between the first magnetic baffle 612 and the second magnetic baffle 622 is greater than the magnetic force between the first magnetic baffle 612 and the first magnetic strip 614, under the attraction of opposite poles, the first magnetic baffle 612 rotates counterclockwise and the second magnetic baffle 622 rotates clockwise. This causes the N pole of the first magnetic baffle 612 and the S pole of the second magnetic baffle 622 to attract each other, thereby connecting the first housing 611 and the second housing 621. When the first connecting component 610 and the second connecting component 620 are separated, the first magnetic baffle 612, under the action of the first magnetic strip 614, rotates clockwise to a vertical position, thereby blocking the aeration pipe 500. At the same time, the second magnetic baffle 622 rotates counterclockwise to a vertical position under the action of the second magnetic strip 624, thereby blocking the air duct 300.

[0043] This configuration ensures that when the first connecting component 610 and the second connecting component 620 are connected, the first magnetic baffle 612 and the second magnetic baffle 622 automatically open, thereby connecting the air pipe 300 and the aeration pipe 500. When the first connecting component 610 and the second connecting component 620 are separated, the first magnetic baffle 612 and the second magnetic baffle 622 respectively block the aeration pipe 500 and the air pipe 300, preventing water from entering.

[0044] Figure 5 A schematic diagram illustrating the structure of the first magnetic baffle in the automatic lifting aeration system provided in an embodiment of the present invention is shown. (Refer to...) Figure 5 In some embodiments of the present invention, both the first magnetic baffle 612 and the second magnetic baffle 622 include a baffle body 6121, a baffle magnetic strip 6122 is provided in the middle of the baffle body 6121, and rotating columns 6123 are symmetrically provided on both sides of the baffle body 6121. The rotating columns 6123 are rotatably connected to the first housing 611 or the second housing 621. In a first state, the baffle magnetic strips 6122 on the first magnetic baffle 612 and the second magnetic baffle 622 are magnetically connected. In a second state, the baffle magnetic strip 6122 on the first magnetic baffle 612 is magnetically connected to the first magnetic strip 614, and the baffle magnetic strip 6122 on the second magnetic baffle 622 is magnetically connected to the second magnetic strip 624.

[0045] Specifically, the baffle body 6121 is disc-shaped, with rotating posts 6123 on both sides of its diameter. The rotating posts 6123 are cylindrical and rotatably connected to the inner walls of the first housing 611 and the second housing 621, respectively. When the rotating posts 6123 rotate to a vertical angle, they can block the first housing 611 and the second housing 621; when they rotate to a horizontal angle, they can connect the first housing 611 and the second housing 621. The baffle magnetic strip 6122 is a strip-shaped permanent magnet embedded in and passing through the baffle body 6121. Through the interaction between the baffle magnetic strip 6122 and the first magnetic strip 614 and the second magnetic strip 624, the baffle body 6121 is driven to rotate. The two ends of the baffle magnetic strip 6122 protrude slightly from the edge of the baffle body 6121, which facilitates the connection between the baffle magnetic strip 6122 and the first magnetic strip 614 and the second magnetic strip 624.

[0046] Reference Figure 1 In some embodiments of the present invention, the lifting rod 200 is movable to the side wall of the pool 900 via the lifting assembly 100, which includes a lifter 110 and a guide rail 120. The guide rail 120 is disposed on the side wall of the pool 900; the lifter 110 is disposed on the guide rail 120 and connected to the lifting rod 200.

[0047] Specifically, the lifting device 110 is an electric slider that can move up and down on the guide rail 120. The guide rail 120 is vertically fixed along the inner wall of the water tank 900. The installation position of the guide rail 120 requires careful design to ensure that the movement of the lifting device 110 on the guide rail 120 can accurately connect the lifting rod 200 to the aeration pipe 500. To make the aeration pipe 500 more stable during lifting, the lifting rod 200 can be connected to the middle of the aeration pipe 500. This design allows the aeration pipe 500 to maintain left-right balance during lifting, thus preventing it from falling due to imbalance.

[0048] Reference Figure 2 In some embodiments of the present invention, the lifting rod 200 and the aeration pipe 500 are magnetically connected by a first magnet 210 and a second magnet 220. The first magnet 210 is fixedly installed on the lifting rod 200, and the second magnet 220 is fixedly installed on the aeration pipe 500.

[0049] Specifically, the first magnet 210 is fixedly installed at the bottom end of the lifting rod 200, and the second magnet 220 is fixedly installed in the middle of the aeration pipe 500. The positions of the first magnet 210 and the second magnet 220 need to be precisely designed so that the lifting rod 200 can align them simply by moving the rod up and down. That is, the first magnet 210 and the second magnet 220 are aligned vertically. The first magnet 210 and the second magnet 220 are specifically disc-shaped structures. Because the upper and lower surfaces of the disc-shaped structure are large, the connection between them can be tighter. The first magnet 210 and the second magnet 220 can be permanent magnets or electromagnets.

[0050] Figure 6 A schematic diagram of the support frame for the automatic lifting aeration system provided in an embodiment of the present invention is illustrated. (Refer to...) Figure 1 and Figure 6 In some embodiments of the present invention, a plurality of support frames 700 are provided at intervals at the bottom of the water tank 900, and the aeration pipe 500 is limited to the support frame 700.

[0051] The support frame 700 includes a support rod and a frame head, with the support rod fixedly installed at the bottom end of the frame head. The bottom end of the support rod is fixedly installed at the bottom of the water tank 900. The frame head has an arc-shaped structure, and its opening size is adapted to the diameter of the aeration pipe 500, allowing the aeration pipe 500 to be confined within the frame head. The support frame 700 mainly serves to support the aeration pipe 500. When setting the position of the support frame 700, the aeration pipe 500 and the support frame 700 must be aligned vertically, so that the aeration pipe 500 can be confined and disengaged from the support frame 700 simply by raising or lowering it.

[0052] Figure 7 A control system diagram of the automatic lifting aeration system provided in an embodiment of the present invention is illustrated. (Refer to...) Figure 1 and Figure 7 In some embodiments of the present invention, the air duct 300 is equipped with a pressure gauge 310, and the water tank 900 is equipped with a dissolved oxygen meter probe 400. The automatic lifting aeration system also includes a PLC control system 800, and the lifting device 110, pressure gauge 310, and dissolved oxygen meter probe 400 are all connected to the PLC control system 800 via signal connection.

[0053] In the above structure, pressure gauge 310 monitors the pressure within air duct 300 in real time, ensuring a stable and continuous supply of gas to the aeration equipment. When abnormal pressure fluctuations occur, pressure gauge 310 sends a signal to notify PLC control system 800 for adjustment. Dissolved oxygen meter probe 400, installed inside water tank 900, monitors the dissolved oxygen content in the water in real time. Dissolved oxygen is a crucial parameter in wastewater treatment, directly affecting the degradation rate of organic matter and the water quality improvement effect. Dissolved oxygen meter probe 400 feeds real-time data back to PLC control system 800 so that the system can adjust the aeration rate as needed. PLC control system 800 is the "brain" of the entire aeration system. It receives signals from pressure gauge 310, dissolved oxygen meter probe 400, and other possible sensors, and automatically adjusts the operating status of the aeration equipment according to preset programs and algorithms, including the rotation speed, aeration rate, and aeration time of PLC control system 800, to achieve optimal aeration results.

[0054] In some possible embodiments, the energy required by the present invention may be provided by a power generation system, which may specifically be a wind power generation system, a photovoltaic power generation system, or a wind-solar hybrid power generation system.
