Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of water treatment, in particular to a floating micro-nano aeration device. BACKGROUND
[0002] In related technologies, the floating micro-nano aeration device is a high-efficiency sewage treatment equipment. In terms of structure, it is usually composed of an aeration host, a floating platform, and connecting components. The floating platform can make the entire device float on the water surface and can flexibly adapt to different water level changes. Its working principle is to generate micro-nano bubbles through the aeration host. The micro-nano bubbles have the characteristics of small particle size, large specific surface area, and slow rising speed. The small particle size enables them to stay in the water for a long time, and the large specific surface area means more gas-liquid contact area, thereby greatly improving the oxygen mass transfer efficiency and more effectively dissolving oxygen into the water body. In terms of application, it is widely used for purification treatment of various water bodies, such as urban landscape lakes, rivers, aquaculture ponds, etc. In landscape water bodies, it can increase the dissolved oxygen in the water, improve the water quality, inhibit the excessive growth of algae, enhance the self-purification ability of the water body, and maintain the clarity and beauty of the water body; in aquaculture, it can provide sufficient oxygen for aquatic organisms such as fish and shrimp, promote their growth, and reduce the occurrence of diseases. Moreover, the device is easy to install and move, and can be flexibly arranged according to actual needs.
[0003] At present, the aeration pipeline is generally installed horizontally, but the horizontal installation position is close to the water surface, so the bubbles may not have fully diffused to the bottom before reaching the water surface and breaking during the rising process. Even if the pipeline installation position is lower, due to the limitations of horizontal arrangement, it is difficult to ensure that the entire bottom water area can be evenly aerated; therefore, it does not meet the existing needs, and for this purpose, we propose a floating micro-nano aeration device.

The bubbles flowing out obliquely downward at a small flow rate can meet the aeration demand while reducing the disturbance to the bottom environment, which helps to maintain the clarity and stability of the water body.

[0040] The side of the air-tight box 4 is fixedly installed with a driving box 6, the side of the driving box 6 is fixedly installed with a servo motor 601, the outer side of the servo motor 601 is provided with a waterproof box, the inner wall of the driving box 6 is rotatably connected with a driving shaft 602, the output shaft of the servo motor 601 penetrates the inner wall of the driving box 6 and is key-connected with the driving shaft 602, the outer side of the driving shaft 602 is fixedly sleeved with a driving gear 603, the inner wall of the driving box 6 is also rotatably connected with two meshing gears 604, respectively, the two meshing gears 604 are meshingly transmitted with the driving gear 603, respectively, the rotating shaft 501 penetrates the driving box 6 and is fixedly connected with the middle part of the meshing gear 604, the two meshing gears 604 are reciprocatingly rotated by the servo motor 601, respectively, as the driving source of the two rotating mechanisms 5.
[0041] The inner wall of the air-tight box 4 is rotatably connected with a connecting column 6021, the other end of the driving shaft 602 is fixedly connected with the end of the connecting column 6021, the bottom of the micro-nano aerator 3 is fixedly connected with a connecting pipe 301, the connecting pipe 301 penetrates the inside of the air-tight box 4 and is fixedly connected with the end of the adjusting mechanism 7.
[0042] The adjusting mechanism 7 comprises an adjusting cylinder 701, the adjusting cylinder 701 is fixedly connected between the connecting pipe 301 and the communication pipeline 8, the surface of the adjusting cylinder 701 is provided with a first bevel gear 702 and a fixed disc 703, respectively, a plurality of connecting rods 704 are fixedly connected between the first bevel gear 702 and the fixed disc 703, the inside of the adjusting cylinder 701 is rotatably connected with a moving disc 7031, the surface of the moving disc 7031 is fixedly connected with the fixed disc 703, and the fixed disc 703 is rotatably sleeved on the outer side of the adjusting cylinder 701, the first bevel gear 702 is rotatably sleeved on the surface of the adjusting cylinder 701.
[0043] The surface of the moving disc 7031 is provided with a first communication hole 705, the inside of the adjusting cylinder 701 is fixedly connected with a rotating disc 706, the surface of the rotating disc 706 is provided with a second communication hole 707, and the fixed disc 703 and the rotating disc 706 are abutted;
[0044] In the initial state, the first communication hole 705 of the aeration hole 507 and the second communication hole 707 are in an incomplete overlapping state. In this case, when the bubbles flow out from the inside of the aeration hole 507, they diffuse along the transverse direction at the maximum flow rate.
[0045] When the servo motor 601 starts, the driving force of the motor causes the cam 506 to start rotating, which in turn drives the aeration hole 507 to rotate. As the aeration hole 507 rotates, the first connecting hole 705 and the second connecting hole 707, which were not originally completely overlapping, gradually adjust to a position where they completely overlap.
[0046] When the first connecting hole 705 and the second connecting hole 707 are completely overlapped, the flow of bubbles from the aeration hole 507 changes significantly. At this time, the bubbles flow out at a relatively low velocity in a downward direction, which effectively avoids the strong impact force that might be generated on the silt at the bottom of the water due to excessive bubble velocity, which could wash up the silt, increase the suspended particles in the water, and ultimately make the water turbid. The bubbles flowing out at a low velocity in a downward direction can meet the aeration requirements while reducing the disturbance to the bottom environment, which helps maintain the clarity and stability of the water.
[0047] The drive shaft 602 extends into 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 meshes with the first bevel gear 702 for transmission. The connecting pipe 301, the adjusting cylinder 701, the connecting pipe 8 and the aeration hole 507 are connected in a continuous manner.
[0048] Through the above technical solution, the floating micro-nano aeration device provided in this disclosure, when in use, is equipped with a rotating mechanism 5, and the servo motor 601 is started. When the servo motor 601 rotates clockwise, it drives the drive shaft 602 and the drive gear 603 on the outside of the drive shaft 602 to rotate. At the same time, the drive gear 603 meshes with two meshing gears 604, causing the two rotating shafts 501 to rotate and drive the two rotating plates 502 to swing. The push rod 504 pulls the cam 506 to rotate on the central shaft, causing the two cams 506 to deflect towards the center. The aeration hole 507 rotates to the downward angle, adjusting the direction of the bubble flow. The two rotating mechanisms 5 are symmetrically arranged, with opposite rotation directions but the same principle. As the aeration hole 507 rotates, it can deliver oxygen to the bottom area of the water body for aeration treatment of the lower part of the water body. When the servo motor 601 rotates counterclockwise, it drives the two cams 506 to rotate in the opposite direction, and the aeration hole 507 resets to aerate the upper part of the water body, so that the entire bottom water body can be aerated more evenly, avoiding local hypoxia.
[0049] For example, in some embodiments, reference Figures 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 moving 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 misaligned. When the bubbles flow out from the aeration hole 507, they diffuse in the lateral direction at the maximum flow rate.
[0050] For example, in some embodiments, reference Figures 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 drive shaft 602 rotates, the second bevel gear 605 meshes with the first bevel gear 702 and drives the fixed disk 703 to rotate synchronously through the connecting rod 704. When the fixed disk 703 drives the moving disk 7031 to rotate, in the second state, the first connecting hole 705 and the second connecting hole 707 gradually overlap, the speed of the bubbles flowing out decreases, and the bubbles can flow from the regulating cylinder 701 to the connecting pipe 8, and then flow through the bellows 801 to the inside of the cam 506, 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 the bubbles flowing out too fast and washing up the silt, making the water turbid. The bubbles flowing out obliquely downward at a smaller flow rate can meet the aeration requirements while reducing the disturbance to the bottom environment, which helps to maintain the clarity and stability of the water body.
[0051] It should be noted that the micro-nano bubbles are generated inside the micro-nano aeration box 3 and transported underwater through the connecting pipe 301, the adjusting mechanism 7, the connecting pipe 8 and the corrugated pipe 801. A sealing element is provided between the corrugated pipe 801 and the extension plate 505. The specific models, working principles and usage of the float 1, the micro-nano aeration box 3 and the sealing element in this solution are well known to those skilled in the art, and will not be elaborated here.

However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.
[0054] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
