Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to a floating micro-nano aeration device. Background Art

[0002] In related technology, floating micro-nano aeration devices are highly efficient wastewater treatment equipment. Structurally, they typically consist of an aerator, a floating platform, and connecting components. The floating platform allows the entire device to float on the water surface, flexibly adapting to varying water level fluctuations. Their operating principle is to generate micro-nano bubbles through the aerator. These bubbles have the characteristics of small particle size, large specific surface area, and slow rise rate. Their small particle size allows them to remain in the water for extended periods, while their large specific surface area provides more gas-liquid contact area, significantly improving oxygen transfer efficiency and enabling more efficient dissolution of oxygen into the water. In terms of applications, they are widely used for purification of various water bodies, such as urban landscape lakes, rivers, and aquaculture ponds. In landscape water bodies, they can increase dissolved oxygen, improve water quality, inhibit excessive algae growth, enhance the water's self-purification capacity, and maintain clear and beautiful water. In aquaculture, they can provide sufficient oxygen for aquatic organisms such as fish and shrimp, promoting their growth and reducing the incidence of disease. Furthermore, the device is simple to install and move, allowing for flexible deployment according to actual needs.

[0003] Currently, aeration pipes are typically installed horizontally. However, this installation position is close to the water surface, so bubbles may burst at the surface before fully diffusing to the bottom. Even if the pipes are installed low, the limitations of a horizontal installation make it difficult to ensure uniform aeration across the entire bottom water area. Therefore, this does not meet existing needs. Therefore, we have proposed a floating micro-nano aeration device. Summary of the Invention

[0004] The present invention provides a floating micro-nano aeration device. The floating micro-nano aeration device can transport oxygen to different areas at the bottom of the water body as the aeration holes rotate, so that the entire bottom water area can be aerated relatively evenly, avoiding local hypoxia. This solves the problem mentioned in the above background technology that when the horizontal installation position is close to the water surface, bubbles may reach the water surface and burst before fully diffusing to the bottom during the rising process. Even if the pipeline is installed at a low position, it is difficult to ensure that the entire bottom water area is evenly aerated due to the limitations of the horizontal installation.

[0005] In order to achieve the above-mentioned object, the present disclosure provides a floating micro-nano aeration device, comprising a float, a support plate and a micro-nano aeration box, wherein an airtight box is provided at the bottom of the micro-nano aeration box, and a rotating mechanism is provided both inside and outside the airtight box; There are two rotating mechanisms, and the two rotating mechanisms are symmetrically arranged. The rotating mechanism includes a rotating shaft rotatably connected to the inner wall of the airtight box, the end of the rotating shaft is fixedly connected to a rotating plate, the surface of the rotating plate is fixedly connected to a fixed block, and the surface of the fixed block is hinged with a push rod. Extension plates are fixedly connected to both sides of the airtight box, and the side surfaces of the extension plates are rotatably connected to a cam through a central axis. Three aeration holes are provided on the side surfaces of the cam, and the push rod passes through the inner wall of the airtight box and is hinged on the surface of the cam. An adjusting mechanism is fixedly installed inside the airtight box, and a connecting pipe is installed below the adjusting mechanism, and the connecting pipe is installed on the side surfaces of the cam.

[0008] Optionally, the inner wall of the airtight box is rotatably connected to a connecting rod, and the other end of the drive shaft is fixedly connected to the end of the connecting rod.

[0009] Optionally, a connecting pipe is fixedly connected to the bottom of the micro-nano aeration box, and the connecting pipe passes through the interior of the airtight box and is fixedly connected to the end of the regulating mechanism.

[0010] Optionally, the adjustment mechanism includes an adjustment cylinder, which is fixedly connected between the connecting pipe and the communicating pipe. A first bevel gear and a fixed disk are respectively provided on the surface of the adjustment cylinder, and a plurality of connecting rods are fixedly connected between the first bevel gear and the fixed disk.

[0012] Optionally, a first communication hole is opened on the surface of the movable disk, a rotating disk is fixedly connected to the inside of the adjusting cylinder, a second communication hole is opened on the surface of the rotating disk, and the fixed disk is arranged in close contact with the rotating disk.

[0014] Optionally, the connecting pipe, the regulating cylinder, the communicating pipe and the aeration hole are connected.

[0015] Through the above technical solution, the floating micro-nano aeration device provided by the present disclosure, when in use: By setting up a rotating mechanism, the traditional horizontal aeration pipe has aeration dead corners, while the aeration holes that can be rotated to the bottom can change the aeration position and direction. As the aeration holes rotate, they can transport oxygen to different areas at the bottom of the water body, so that the entire bottom water area can be aerated more evenly, avoiding local hypoxia. By providing an adjustment mechanism, the first and second connecting holes of the aeration holes do not completely overlap in the initial state. In this situation, bubbles exiting the aeration holes diffuse laterally at maximum velocity. When the aeration holes rotate downward, the first and second connecting holes completely overlap. The adjustment mechanism allows the bubbles to flow downward at a relatively low velocity, effectively preventing excessive bubble velocity from stirring up silt and causing water turbidity. The bubbles flowing downward at a low velocity meet aeration requirements while minimizing disturbance to the underwater environment, helping to maintain water clarity and stability.

[0033] According to some embodiments of the present disclosure, a floating micro-nano aeration device is provided, referring to Figure 1-12 As shown in the figure, the floating micro-nano aeration device includes a float 1, a support plate 2 and a micro-nano aeration box 3. The float 1 is used to drive the support plate 2 and the micro-nano aeration box 3 to float on the water surface. The micro-nano aeration box 3 is used to generate micro-nano bubbles. An airtight box 4 is provided at the bottom of the micro-nano aeration box 3. A rotating mechanism 5 is provided inside and outside the airtight box 4. There are two rotating mechanisms 5, and the two rotating mechanisms 5 are symmetrically arranged. The rotating mechanism 5 includes a rotating shaft 501 rotatably connected to the inner wall of the airtight box 4, and a rotating plate 502 is fixedly connected to the end of the rotating shaft 501. The surface of the rotating plate 502 is fixedly connected to the fixed block 503, and the surface of the fixed block 503 is hinged with a push rod 504. Extension plates 505 are fixedly connected to both sides of the airtight box 4. The side of the extension plate 505 is rotatably connected to the cam 506 through the central axis. Three aeration holes 507 are provided on the side of the cam 506. The push rod 504 passes through the inner wall of the airtight box 4 and is hinged on the surface of the cam 506. An adjusting mechanism 7 is fixedly installed inside the airtight box 4, and a connecting pipe 8 is installed below the adjusting mechanism 7. The connecting pipe 8 is installed on the side of the cam 506.

[0034] In addition, a bellows 801 is fixedly connected to the end of the connecting pipe 8, and the end of the bellows 801 is fixedly connected to the side of the cam 506. The micro-nano bubbles generated by the micro-nano aeration box 3 flow into the connecting pipe 8 and flow into the water through the bellows 801 and the aeration holes 507.

[0035] A drive box 6 is fixedly installed on the side of the airtight box 4, and a servo motor 601 is fixedly installed on the side of the drive box 6. A waterproof box is provided on the outside of the servo motor 601. The inner wall of the drive box 6 is rotatably connected to the drive shaft 602. The output shaft of the servo motor 601 passes through the inner wall of the drive box 6 and is key-connected to the drive shaft 602. A drive gear 603 is fixedly sleeved on the outside of the drive shaft 602. The inner wall of the drive box 6 is also rotatably connected to two meshing gears 604, and the two meshing gears 604 are respectively meshed with the drive gear 603 for transmission. The rotating shaft 501 passes through the drive box 6 and is fixedly connected to the middle of the meshing gear 604. The two meshing gears 604 and the two rotating shafts 501 are respectively rotated back and forth by the servo motor 601, serving as the driving source of the two rotating mechanisms 5.

[0036] The inner wall of the airtight box 4 is rotatably connected to a connecting column 6021, and the other end of the drive shaft 602 is fixedly connected to the end of the connecting column 6021. The bottom of the micro-nano aeration box 3 is fixedly connected to a connecting pipe 301, which passes through the interior of the airtight box 4 and is fixedly connected to the end of the adjustment mechanism 7.

[0037] The adjusting mechanism 7 includes an adjusting cylinder 701, which is fixedly connected between the connecting pipe 301 and the communicating pipe 8. A first bevel gear 702 and a fixed disk 703 are respectively provided on the surface of the adjusting cylinder 701. Several connecting rods 704 are fixedly connected between the first bevel gear 702 and the fixed disk 703. A movable disk 7031 is rotatably connected inside the adjusting cylinder 701. The fixed disk 703 is fixedly connected to the surface of the movable disk 7031, and the fixed disk 703 is rotatably sleeved on the outside of the adjusting cylinder 701. The first bevel gear 702 is rotatably sleeved on the surface of the adjusting cylinder 701.

[0038] A first connecting hole 705 is formed on the surface of the movable disk 7031. A rotating disk 706 is fixedly connected to the inside of the adjusting cylinder 701. A second connecting hole 707 is formed on the surface of the rotating disk 706. The fixed disk 703 is fitted with the rotating disk 706. In the initial state, the first communicating hole 705 and the second communicating hole 707 of the aeration hole 507 are not completely overlapped. In this case, when the bubbles flow out from the aeration hole 507, they diffuse in the lateral direction at the maximum flow rate.

[0039] When the servo motor 601 is started, the driving force of the motor causes the cam 506 to start rotating, further driving the aeration hole 507 to rotate. As the aeration hole 507 rotates, the first communication hole 705 and the second communication hole 707, which were originally not completely overlapped, gradually adjust to a completely overlapping position.

[0040] When the first connecting hole 705 and the second connecting hole 707 completely overlap, the flow of bubbles from the aeration hole 507 changes significantly. Now, the bubbles flow out at a relatively low velocity and in a diagonally downward direction. This effectively prevents excessive bubble velocity from creating a strong impact on the silt at the bottom of the water, which could cause it to lift up, increase suspended particles in the water, and ultimately cause the water to become turbid. The low, diagonally downward flow of bubbles ensures aeration while minimizing disturbance to the underwater environment, helping to maintain water clarity and stability.

[0041] The drive shaft 602 extends to the interior of the airtight box 4, and the end of the connecting column 6021 is fixedly connected to the second bevel gear 605, the second bevel gear 605 is engaged with the first bevel gear 702 for transmission, and the connecting pipe 301, the regulating cylinder 701, the connecting pipe 8 and the aeration hole 507 are connected.

[0042] According to the above technical solution, when the floating micro-nano aeration device provided by the present disclosure is used, the rotation mechanism 5 is provided to start the servo motor 601. When the servo motor 601 rotates clockwise, it drives the drive shaft 602 and the drive gear 603 outside the drive shaft 602 to rotate. At the same time, the drive gear 603 engages with the two meshing gears 604, causing the two rotating shafts 501 to rotate and driving the two rotating plates 502 to swing. The push rod 504 pulls the cam 506 to rotate on the central axis, causing the two cams 506 to deflect toward the center, and the aeration hole 507 to rotate obliquely downward to adjust the direction of bubble outflow. The two rotating mechanisms 5 are symmetrically arranged and rotate in opposite directions. The principle is the same. As the aeration hole 507 rotates, it can transport oxygen to the bottom area of ​​the water body, aerating the lower water area. When the servo motor 601 rotates counterclockwise, it drives the two cams 506 to rotate in the opposite direction, and the aeration hole 507 is reset to aerate the upper water area, so that the entire bottom water area can be aerated more evenly, avoiding local hypoxia. For example, in some embodiments, reference Figure 1-11 As shown, the first connecting hole 705 and the second connecting hole 707 can have a first state. The first state is when the fixed disk 703 does not drive the movable disk 7031 to rotate. In the first state, the first connecting hole on the fixed disk 7031 and the second connecting hole 707 on the rotating disk 706 are staggered. When the bubbles flow out from the inside of the aeration hole 507, they diffuse in the lateral direction at the maximum flow rate.

[0043] For example, in some embodiments, reference Figure 1-12 As shown, the first connecting hole 705 and the second connecting hole 707 can have a second state. In the second state, when the driving shaft 602 rotates, the second bevel gear 605 engages with the first bevel gear 702 for transmission, and synchronously drives the fixed disk 703 to rotate through the connecting rod 704. When the fixed disk 703 drives the movable disk 7031 to rotate, in the second state, the first connecting hole 705 and the second connecting hole 707 gradually overlap, and the speed of bubble outflow becomes smaller. The bubbles can flow from the regulating cylinder 701 to the connecting pipe 8, and then flow to the inside of the cam 506 through the bellows 801, and flow out obliquely downward from the aeration hole 507. The bubbles flow out obliquely downward at a relatively small flow rate, which can effectively avoid the problem of excessive bubble flow rate causing silt to be washed away and making the water quality turbid. The bubbles flowing out obliquely downward at a small flow rate can meet the aeration requirements while reducing the disturbance to the underwater environment, thereby helping to maintain the clarity and stability of the water body.

[0044] It should be noted that micro-nano bubbles are generated inside the micro-nano aeration box 3 and transported underwater through the connecting pipe 301, the regulating mechanism 7, the connecting pipe 8, and the bellows 801. A seal is provided between the bellows 801 and the extension plate 505. The specific models, working principles, and usage of the float 1, micro-nano aeration box 3, and seal in this solution are well known to those skilled in the art and are not elaborated on here.

[0045] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction.
