Description

Technical Field

[0001] This invention relates to the field of aeration device technology, and more specifically, to a circulating aeration device for lake water pollution treatment. Background Technology

[0002] Eutrophication, organic matter accumulation, and hypoxia in lakes are the core problems of current water pollution in natural water bodies. Long-term hypoxia leads to reduced activity of aquatic microorganisms and decreased pollutant degradation capacity, resulting in a series of environmental problems such as blackening and foul odors, algal blooms, and aquatic ecological imbalance. Aeration is a core technical means for the ecological treatment of lake pollution. By continuously introducing air into the water, it increases the dissolved oxygen content, activates the decomposition and metabolism of native microorganisms, accelerates the degradation and transformation of organic matter and nitrogen and phosphorus pollutants in the water, improves the stratified hypoxic state of the water body, and restores the aquatic ecological cycle system. Floating circulating aeration devices, with their advantages of convenient deployment, no need for civil engineering foundations, ability to operate across the entire water surface, and strong adaptability, have become the mainstream equipment for in-situ lake treatment. They are widely used in the routine water quality purification and treatment of natural lakes, scenic water areas, and stagnant water bodies in rivers, playing a vital role in maintaining the self-purification capacity of lakes and ensuring the stability of aquatic ecosystems.

[0003] Existing floating aeration devices for lake water pollution treatment mainly adopt an overall structure with a floating body carrying an aerator head. The device is deployed floating on the water surface by relying on the buoyancy of the floating body. Air is introduced into the underwater aerator head through a top fan and air supply pipe, and the water is oxygenated by the diffusion of bubbles, thereby purifying the water.

[0004] However, during the use of the aforementioned existing floating aeration equipment, in windy weather, the floating body of the aeration equipment on the lake surface is easily affected by the continuous wind force, causing the aeration equipment to tilt. This causes the underwater aeration head of the equipment to deflect accordingly. The inner cavity of the aeration head is a closed pressure-stabilizing chamber. When the chamber is level, the static pressure inside the chamber is equal everywhere, and the bubbles can diffuse evenly to the surrounding water, ensuring a uniform dissolved oxygen (DO) concentration in the aerated lake water. If the aeration head is continuously tilted, the chamber will have a height difference after tilting. The gas will be buoyed and accumulate at the higher position of the chamber. High-pressure gas will be concentrated and overflow from the air holes at the higher position, while the air pressure at the lower position will be insufficient. The gas output will decrease gradually along the tilting direction, causing the bubbles to deflect to one side. The DO in one area will be too high and the other side will be too low, affecting the activity of microorganisms and the degradation efficiency of pollutants. The tilting of the aeration equipment due to the above-mentioned wind force over a long period of time will undoubtedly significantly reduce its water pollution treatment efficiency and effect.

[0005] In view of this, the present invention proposes a circulating aeration device for the efficient and stable treatment of lake water pollution. Summary of the Invention

[0006] Technical problem to be solved: The purpose of this invention is to provide a circulating aeration device for lake water pollution treatment, which solves the technical problems mentioned in the background art.

[0007] Technical Solution: This invention provides a circulating aeration device for lake water pollution treatment, including a float. The float is a frustum-shaped structure, wider at the top and narrower at the bottom. An inner cylinder is installed inside the float, dividing the inside of the float into an annular cavity structure. A fixed column is installed inside the inner cylinder, rotatably connected to the inner cylinder. An aeration component is installed axially inside the fixed column. An angle sensor is fixed to one side of the fixed column. A first fixed ring and a second fixed ring are sleeved and fixed to the outer wall of the fixed column. Two electric rollers are mirror-fixed to the side wall of the first fixed ring, rolling against the top surface of the float. The second fixed ring is against the bottom surface of the float. A balancing mechanism is fixed to the side wall of the fixed column, against the outer wall of the float. The bottom end of the balancing mechanism is fixed to the side wall of the second fixed ring. The first fixed ring rolls on the top surface of the float via electric rollers, causing the fixed column to drive the balancing mechanism to rotate on the float, thereby adjusting the balance of the float 360°. The balancing mechanism includes a scraper fixed to the side wall of the fixed column. There are two scraper fixed in mirror image about the vertical centerline of the fixed column. The two scraper are arranged radially along the float. A sliding adjustment component for moving the counterweight is fixed on the top surface of the scraper. The sliding adjustment component adjusts the position of the counterweight in the horizontal direction along the top surface of the scraper.

[0008] Furthermore, the scraper has a "7" shaped structure, and the scraper is attached to the top surface and side wall of the pontoon. The bottom end of the scraper is fixed to the side wall of the second fixing ring.

[0009] Furthermore, the sliding adjustment assembly includes two slide rails respectively fixed to the top surfaces of the two scraping racks. The two slide rails are mirror images of each other. A counterweight component is slidably connected to the top surface of each slide rail. Two storage slots are opened on the side wall of the first fixing ring. The counterweight component is inserted into the storage slot by sliding along the slide rail.

[0010] Furthermore, the counterweight component includes an electric slider that is slidably connected to the top surface of the slide rail, and a pusher block is fixed to the bottom surface of the electric slider. There are two pusher blocks that are fixed in a mirror image about the vertical center line of the electric slider.

[0011] Furthermore, the top of the scraper frame is a horizontal section, and the two sides of the horizontal section of the scraper frame are inclined structures. The two pusher blocks are slidably attached to the two inclined surfaces of the horizontal section of the scraper frame, and the bottom surface of the pusher blocks is slidably attached to the top surface of the float.

[0012] Furthermore, the sliding adjustment assembly also includes a water injection component that penetrates and connects to the inside of the fixed column. The bottom end of the water injection component is a water extraction end, which extends outward from the bottom end of the fixed column. One end of the slide rail is inserted into the inside of the fixed column. The inside of the slide rail is a cavity structure. Multiple water spray holes that communicate with the cavity structure are opened on the bottom surface of the slide rail. The multiple water spray holes are respectively set on the top of the two inclined surfaces of the horizontal section of the scraper. The water injection component is provided with two water outlets, which are respectively connected to the cavity structures inside the two slide rails.

[0013] Furthermore, the water injection component includes a water pump that penetrates and is connected inside the fixed column. A water pump is connected to one side of the water pump and is connected to the bottom of the fixed column. A three-way valve is connected to one end of the water pump, and the other two ends of the three-way valve are respectively connected to two slide rails with water distribution pipes.

[0014] Furthermore, the water injection component also includes a filter cartridge that extends through and is connected to the bottom end of the water pumping pipe, with a filter plug inserted into the bottom end of the filter cartridge.

[0015] Furthermore, the filter cartridge is filled with ion exchange resin particles.

[0016] Furthermore, the aeration assembly includes an aeration fan fixed to the top of the fixed column, an air pipe connected to the bottom of the aeration fan, the air pipe being connected through to the bottom of the fixed column, an aeration head being connected through to the bottom of the air pipe, a mesh cover being fitted onto the outer wall of the aeration head, a fixing rod being fixed to the top surface of the aeration head, and the top of the fixing rod being fixed to the bottom of the fixed column.

[0017] Beneficial effects: One or more technical solutions provided in this invention have at least the following technical effects or advantages: 1. The entire system utilizes a frustum-shaped pontoon for buoyancy, with an internal fixed column and an axially connected aeration assembly to achieve continuous aeration and oxygenation of the water. The fixed column is equipped with an angle sensor to collect real-time tilt data. An electric roller on the first fixed ring can roll along the top surface of the pontoon, driving the fixed column and balancing mechanism to rotate 360°. After rotating to the unbalanced direction, the sliding adjustment assembly can move horizontally along the scraper frame to adjust the counterweight position. Combined with the rotation direction and counterweight displacement adjustment, this system can adapt to the continuous tilting caused by strong winds, adaptively correcting the equipment's attitude balance to ensure that the aeration assembly is always in a vertical state. This ensures the uniformity of the aeration direction and aeration volume distribution, resulting in a uniform dissolved oxygen concentration in the lake's aeration area. This guarantees microbial activity and pollutant degradation efficiency, thereby ensuring the efficiency and effectiveness of aeration treatment for lake water pollution.

[0018] 2. A mirror-arranged slide rail is installed on the top surface of the sweeper. This not only rotates the counterweight component to move linearly along the track to the tilt direction, but also allows the sweeper to rotate and remove surface deposits. This reduces the impact of uneven gravity distribution caused by surface deposits in strong winds, which exacerbates the tilting. It also reduces the counterweight adjustment range and improves the efficiency of counterweight adjustment. The first fixing ring has a storage groove, which can be stored in the counterweight component after it slides, achieving idle protection and reducing the interference and corrosion of the component by water and debris.

[0019] 3. The electric slider serves as the main body of the movable counterweight. Combined with two symmetrically arranged push blocks at the bottom, it simultaneously completes the counterweight adjustment and impurity pushing operations, improving the functionality of the counterweight components, promptly removing surface impurities that have been scraped off, and ensuring the stability of the counterweight balance adjustment in subsequent stable adjustments.

[0020] 4. The horizontal section of the scraper frame is equipped with inclined surfaces on both sides to facilitate the removal of impurities. The pusher block slides against the inclined surface and the top surface of the float. The contact surface is tightly fitted and the movement is highly directional, which can continuously push scattered impurities and avoid impurities from accumulating and affecting subsequent counterweight adjustment.

[0021] 5. A water injection component is installed through the fixed column to introduce lake water into the hollow slide rail. Water spray holes are arranged on the bottom surface of the slide rail, and the water flow is sprayed in a direction to the inclined area of ​​the scraper frame to achieve targeted flushing and cleaning and surface lubrication. The water injection component supplies water to the slide rails on both sides in two ways to ensure that the two sets of scrapers are cleaned and lubricated at the same time, effectively reducing sliding resistance, preventing dirt accumulation, and ensuring the stability of subsequent gravity adjustment.

[0022] 6. A filter cartridge and filter plug are installed at the bottom of the water pump to form a primary filtration structure, which can intercept large impurities such as suspended particles and aquatic plant debris in the water. This protects the water pipes, pumps and nozzles from the source, reduces blockages, and ensures the continuous operation of the water supply system.

[0023] 7. The filter cartridge is filled with ion exchange resin particles, which can adsorb scale-forming ions such as calcium and magnesium ions in the water, preventing scale formation from the source. Combined with the front-end filter plug, it forms a multi-stage purification process. The treated water is used for flushing and lubrication, completely eliminating the problem of scaling and blockage, and ensuring the long-term flexible operation of the sliding adjustment component.

[0036] Reference Figures 1-8 This invention provides a circulating aeration device for lake water pollution treatment, including a float 100. The float 100 has a frustum-shaped structure that is wider at the top and narrower at the bottom. An inner cylinder is installed inside the float 100, dividing the interior of the float 100 into an annular cavity structure. A fixing column 200 is installed inside the inner cylinder of the float 100 and is rotatably connected to the interior of the inner cylinder. An aeration assembly 300 is installed axially inside the fixing column 200. An angle sensor 900 is fixed to one side of the fixing column 200. A first fixing ring 400 and a second fixing ring 400 are sleeved and fixed to the outer wall of the fixing column 200. The first fixed ring 400 has two electric rollers 500 fixed to its side wall in a mirror image. The electric rollers 500 roll and adhere to the top surface of the float 100. The second fixed ring 800 adheres to the bottom surface of the float 100. The side wall of the fixed column 200 is fixed with a balancing mechanism, which adheres to the outer wall of the float 100. The bottom end of the balancing mechanism is fixed to the side wall of the second fixed ring 800. The first fixed ring 400 rolls on the top surface of the float 100 through the electric rollers 500, so that the fixed column 200 drives the balancing mechanism to rotate on the float 100, so that the balancing mechanism can adjust the balance of the float 100 360° on the float 100. The balancing mechanism includes a scraper 600 fixed to the side wall of the fixed column 200. There are two scraper 600s fixed in mirror image about the vertical centerline of the fixed column 200. The two scraper 600s are radially distributed along the float 100. A sliding adjustment component 700 for moving the counterweight is fixed on the top surface of the scraper 600. The sliding adjustment component 700 adjusts the position of the counterweight in the horizontal direction along the top surface of the scraper 600. The entire system utilizes a frustum-shaped pontoon 100 for buoyancy, with a fixed column 200 and an axially connected aeration component 300 inside to achieve continuous aeration and oxygenation of the water. The fixed column 200 is equipped with an tilt sensor 900 to collect real-time tilt data. The electric roller 500 on the first fixed ring 400 can roll along the top surface of the pontoon 100, driving the fixed column 200 and the balancing mechanism to rotate 360°. After rotating to the unbalanced direction, the sliding adjustment component 700 can move horizontally along the scraper frame 600 to adjust the position of the counterweight. Combined with the rotation direction and counterweight displacement adjustment, this system can cope with the continuous tilting of the device caused by strong winds, adaptively correcting the device's attitude balance and ensuring that the aeration component 300 is always in a vertical state. This ensures the uniformity of the aeration direction and aeration volume distribution, resulting in a uniform dissolved oxygen concentration in the lake's aeration area, guaranteeing microbial activity and pollutant degradation efficiency, and thus ensuring the efficiency and effectiveness of aeration treatment for lake water pollution.

[0037] In this embodiment, the scraper 600 has a "7" shaped structure. The scraper 600 is attached to the top surface and side wall of the float 100, and the bottom end of the scraper 600 is fixed to the side wall of the second fixing ring 800. The scraper 600 adopts a "7" shaped structure, and is attached to both the top surface and side wall of the float 100 to achieve full-area surface cleaning. The bottom end is fixed on the second fixing ring 800, forming a double-point fixation from top to bottom. The structure is stable and there is no shaking during rotation, ensuring the effect of removing impurities.

[0038] In this embodiment, the sliding adjustment assembly 700 includes two slide rails 710 respectively fixed to the top surfaces of two scraping racks 600. The two slide rails 710 are mirror images of each other. A counterweight component is slidably connected to the top surface of each slide rail 710. Two storage slots 410 are opened on the side wall of the first fixing ring 400. The counterweight component is slidably inserted into the storage slot 410 along the slide rail 710. A mirror-arranged slide rail 710 is installed on the top surface of the scraper frame 600 to provide a linear motion track for the counterweight components, ensuring precise and controllable counterweight displacement. A storage groove 410 is provided on the first fixing ring 400, allowing the counterweight components to be stored in the groove after sliding, achieving idle protection and reducing interference and corrosion of the components by water and debris. A mirror-arranged slide rail 710 is installed on the top surface of the scraper frame 600. This not only rotates and drives the counterweight component to move linearly along the track to the tilt direction, but also allows the scraper frame 600 to rotate and remove surface deposits. This reduces the impact of uneven gravity distribution caused by surface deposits in strong winds, which exacerbates the tilting, reduces the counterweight adjustment range, and improves the efficiency of counterweight adjustment. The first fixing ring 400 has a storage groove 410. After the counterweight component slides, it can be stored in the groove, achieving idle protection and reducing the interference and corrosion of water and debris on the component.

[0039] In this embodiment, the counterweight component includes an electric slider 720 slidably connected to the top surface of the slide rail 710. A pusher block 730 is fixed to the bottom surface of the electric slider 720, and two pusher blocks 730 are fixed in a mirror image about the vertical center line of the electric slider 720. The electric slider 720, as the main moving counterweight, combined with the two symmetrically arranged pusher blocks 730 at the bottom, simultaneously completes the counterweight adjustment and impurity pushing operations, improving the functionality of the counterweight component. It promptly removes surface impurities that have been scraped off, ensuring the stability of the counterweight balance adjustment in subsequent stable adjustments. The symmetrical arrangement of the two pusher blocks 730 ensures balanced force distribution and smooth operation when pushing impurities, stably pushing the scraped debris outwards.

[0040] In this embodiment, the top of the scraper 600 is a horizontal section, and the two sides of the horizontal section of the scraper 600 are inclined structures. Two pusher blocks 730 are respectively slidably attached to the two inclined surfaces of the horizontal section of the scraper 600, and the bottom surface of the pusher block 730 is slidably attached to the top surface of the float 100. The inclined surfaces on both sides of the horizontal section of the scraper 600 facilitate the removal of impurities. The pusher block 730 slides against the inclined surface and the top surface of the float 100. The contact surfaces are tightly attached and the movement is highly directional, which can continuously push scattered impurities and avoid impurities from accumulating and affecting subsequent counterweight adjustment.

[0041] In this embodiment, the sliding adjustment assembly 700 further includes a water injection component 740 that penetrates and connects to the inside of the fixed column 200. The bottom end of the water injection component 740 is a water pumping end, which extends outward from the bottom end of the fixed column 200. One end of the slide rail 710 is inserted into the inside of the fixed column 200. The inside of the slide rail 710 is a cavity structure. The bottom surface of the slide rail 710 is provided with a plurality of water spray holes 711 that communicate with the cavity structure. The plurality of water spray holes 711 are respectively set at the top of the two inclined surfaces of the horizontal section of the scraper frame 600. The water injection component 740 is provided with two water outlets, which are respectively connected to the cavity structures inside the two slide rails 710. A water injection component 740 is installed through the fixed column 200 to introduce lake water into the hollow slide rail 710. Water spray holes 711 are arranged on the bottom surface of the slide rail 710, and the water flow is sprayed in a direction to the inclined area of ​​the scraper frame 600 to achieve targeted flushing and cleaning and surface lubrication. The water injection component 740 supplies water to the slide rails 710 on both sides in two ways to ensure that the two sets of scraper frames 600 are cleaned and lubricated at the same time, effectively reducing sliding resistance, preventing dirt accumulation, and ensuring the stability of subsequent gravity adjustment.

[0042] In this embodiment, the water injection component 740 includes a water pump 741 that penetrates and is connected inside the fixed column 200. A water pump 741 is connected to a water suction pipe 744 on one side. The water suction pipe 744 penetrates and is connected to the bottom end of the fixed column 200. A three-way valve 742 is connected to one end of the water pump 741. The other two ends of the three-way valve 742 are respectively connected to two slide rails 710 through water distribution pipes 743. The water injection component 740 consists of a water pump 741, a water suction pipe 744, a three-way valve 742, and a water distribution pipe 743. The water pump 741 provides stable water pumping power, the three-way valve 742 realizes water diversion, and supplies water evenly to the two slide rails 710 to ensure that the water flow on both sides is consistent and the flushing and lubrication effect is the same. The water suction pipe 744 is laid along the fixed column 200, the water intake position is stable, the water flow is smooth, and it is not easy to get blocked.

[0043] In this embodiment, the water injection component 740 further includes a filter cartridge 745 that is connected to the bottom end of the water pumping pipe 744, and a filter plug 746 is inserted into the bottom end of the filter cartridge 745. The filter cartridge 745 and the filter plug 746 are installed at the bottom end of the water pumping pipe 744 to form a primary filtration structure, which can intercept large impurities such as suspended particulate matter and aquatic plant debris in the water, protect the water pipes, water pump 741 and water spray hole 711 from the source, reduce blockage failures, and ensure the continuous operation of the water supply system.

[0044] In this embodiment, the filter cartridge 745 is filled with ion exchange resin particles. The ion exchange resin particles can adsorb scale-forming ions such as calcium and magnesium ions in the water, thus preventing scale formation at the source. Together with the front-end filter plug 746, it forms a multi-stage purification process. The treated water is used for flushing and lubrication, completely eliminating the problem of scaling and blockage, and ensuring the long-term flexible operation of the sliding adjustment component 700.

[0045] In this embodiment, the aeration assembly 300 includes an aeration fan 310 fixed to the top of the fixed column 200, an air pipe 320 connected to the bottom of the aeration fan 310, the air pipe 320 being connected through to the bottom of the fixed column 200, an aeration head 340 being connected through to the bottom of the air pipe 320, a mesh cover 350 being sleeved on the outer wall of the aeration head 340, a fixing rod 330 being fixed to the top surface of the aeration head 340, and the top of the fixing rod 330 being fixed to the bottom of the fixed column 200. The aeration assembly 300 consists of an aeration blower 310, an air pipe 320, and an aeration head 340, which completes high-pressure air delivery and water aeration. A mesh cover 350 is installed on the outside of the aeration head 340 to physically isolate aquatic plants and suspended debris and prevent the aeration holes from being blocked. A fixing rod 330 is added to connect the aeration head 340 to the bottom of the fixing column 200 to achieve rigid positioning, resist water flow impact, ensure the stability of the position of the aeration head 340, uniform air output, and continuous and stable completion of water oxygenation operation.

[0046] Specifically, according to Figures 1-8As shown, the entire device floats on the lake surface using the buoyancy of the float 100. The external circuit system supplies power to the various electrical components, and the main controller controls and receives signals from the electrical components. The tilt sensor 900 on the fixed column 200 monitors the tilt angle of the entire device in the water in real time and sends the tilt signal to the main controller. When aerating normally on the water surface, the aeration fan 310 is started, and the water inside the lake is aerated through the air pipe 320 and the aeration head 340 to increase the oxygen content in the water and activate microorganisms to treat organic matter in the water, thereby improving the sewage treatment effect. A mesh cover 350 is attached to the outside of the aeration head 340 for protection to ensure the stability and safety of aeration. During long-term aeration, in windy weather, the device experiences a significant and continuous tilt due to the influence of wind and waves. This tilt causes the aeration heads at the bottom (340°) to tilt as well, resulting in an uneven distribution of dissolved oxygen concentration in the aeration area. This leads to inconsistent decomposition by microorganisms and reduces the effectiveness of aeration in treating water pollution. Therefore, when the device tilts continuously, the tilt sensor (90°) sends the detected tilt data, including the tilt angle and direction, to the main controller. The main controller then controls the two electric rollers (50°) to... The top surface of the float 100 rolls, and the first fixing ring 400 drives the fixing column 200 to rotate inside the float 100. The fixing column 200 drives the two scraping frames 600 to rotate. The scraping frames 600 are attached to the top surface and side wall of the float 100 and rotate to scrape away the impurities on the surface of the float 100. The two scraping frames 600 are mirrored in the radial direction of the float 100, which can make the whole device symmetrical and balanced after the scraping frames 600 rotate and clean. Compared with the unidirectional scraping cleaning structure, it is easier to adjust the balance after cleaning. Unidirectional scraping cleaning will result in a more uneven weight distribution, thus increasing the difficulty of balancing. Simultaneously, the main controller starts the water pump 741, which draws lake water through the filter plug 746 into the filter cartridge 745. The filter plug 746 is made of sponge material. After being filtered inside the filter cartridge 745, the water then passes sequentially through the water intake pipe 744, the water pump 741, the three-way valve 742, and the two water distribution pipes 743, entering the hollow structures of the two slide rails 710 respectively. Water is then sprayed onto the scraper frame 600 through the water spray holes 711 on the bottom surface of the slide rails 710, rinsing the scraper frame 600. This not only prevents scraped impurities from adhering to the scraper frame 600, but also cleans the scraper frame 600. The surface acts as a lubricant, and then the main controller simultaneously starts two electric sliders 720 to slide on the slide rail 710. The electric sliders 720 slide out of the storage groove 410 and drive the pusher block 730 to slide on the scraper frame 600. Since the scraper frame 600 is pre-lubricated with water, the sliding resistance of the electric sliders 720 and the pusher block 730 is reduced. The pusher block 730 pushes the scraped impurities from the center of the float 100 to the periphery, pushing the impurities off the float 100, thus avoiding interference and obstruction of the subsequent sliding balance operation of the electric sliders 720 and the pusher block 730. After cleaning the surface of the float 100, the tilt sensor 900 monitors the overall tilt data of the device. If tilting still exists, the main controller controls the electric roller 500 to rotate, rotating the scraper 600 to the tilt direction. Then, the two electric sliders 720 are started to slide on the slide rail 710. Using the electric sliders 720 and the pusher block 730 as counterweights, the overall weight distribution of the device is adjusted, thereby adjusting in the tilt direction to make the device balanced. After the tilt sensor 900 detects that the device has been adjusted to a balanced state, the electric sliders 720 are stopped from sliding to adjust the counterweight. At this time, the overall balance adjustment of the device is completed, thereby ensuring the aeration angle and range of the aeration head 340, and thus ensuring the efficiency and effect of the device in aeration treatment of lake water pollution. When the device tilts due to strong winds or other abnormal weather, or when the device tilts due to a combination of the above two situations, the above steps should be followed to first clean the surface of the float 100, and then adjust the direction and position of the overall counterweight of the device until the device is balanced again for aeration treatment. Because the lake water contains a large amount of calcium and magnesium ions, the introduction of oxygen during aeration will promote the formation of calcium carbonate and a small amount of magnesium hydroxide microcrystals or precipitates. Since the pumping position is close to the aeration position, when water from the aeration position is directly pumped, the water containing calcium carbonate and a small amount of magnesium hydroxide microcrystals or precipitates will wash the surface of the scraper frame 600. Over time, this washing will cause scale to form on the surface of the scraper frame 600, causing the electric slider 720 to get stuck on the scraper frame 600 when it drives the pusher block 730 to slide. This will affect the adjustment of the counterweight balance. To avoid the effects of scale formation, the filter cartridge 745 is filled with plasma exchange resin particles as the filter medium. The plasma exchange resin particles are used to filter out the calcium and magnesium ions that are about to form microcrystals or precipitates, thereby preventing scale formation, ensuring the washing and lubrication effect, and thus ensuring the stability of the overall balance adjustment of the device, ensuring the efficiency and effectiveness of the device in treating lake water pollution through aeration.
