Description

Technical Field

[0001] This invention relates to the field of wastewater aeration treatment technology, and more specifically, to an aeration device and its usage method. Background Technology

[0002] A photovoltaic micro-powered aeration device is a device that uses solar photovoltaic panels to convert solar energy into electrical energy, providing power for aeration and other processes in wastewater treatment. It boasts advantages such as being environmentally friendly and having low operating costs. The solar photovoltaic panels convert solar energy into electrical energy, which is then stored in a battery. During wastewater treatment, the battery powers the aeration system and other equipment, causing the aeration device to generate bubbles, increasing the dissolved oxygen content in the wastewater, and promoting the decomposition of organic matter by microorganisms, thereby achieving wastewater purification.

[0003] A search revealed a decentralized photovoltaic micro-powered integrated aeration device for rural domestic sewage treatment, disclosed in announcement number CN208948979U. While the nanoporous aeration pipes of this device can efficiently refine air into tiny bubbles and uniformly inject them into the sewage due to their microporous structure, the aeration direction is fixed in a single direction, making it impossible to dynamically adjust the aeration angle or direction according to actual operating conditions. This deficiency is particularly prominent in complex sewage treatment scenarios. For example, when there are localized anoxic areas in the sewage tank and aeration needs to be enhanced for specific pollutant layers, a fixed aeration direction can lead to reduced oxygen utilization, uneven treatment efficiency, and even localized sludge deposition or short-circuiting. Summary of the Invention

[0004] To address the problems mentioned in the background art, this application proposes an aeration device and its usage method.

[0005] An aeration device and its usage method include a floating frame, an aeration pipe on the outer side of the floating frame, four photovoltaic panels arranged in a circular array fixedly installed on the top surface of the floating frame, a control box corresponding to the aeration pipe and photovoltaic panels fixedly installed at the center of the top surface of the floating frame, several sets of aeration micro-holes on the four sides of the aeration pipe, adjustment components for adjusting the direction and air output of the aeration micro-holes on the four sides of the aeration pipe, four sets of drive components for driving the adjustment components on the outer wall of the aeration pipe, collection components for collecting rainwater at the bottom of the four photovoltaic panels, and cleaning components corresponding to the adjustment components at the bottom of the four collection components.

[0006] The adjustment component includes a mounting bracket symmetrically fixedly installed on the side of the float, with an adjustment sleeve rotatably installed on the inner wall of the mounting bracket, and the adjustment sleeve rotatably fitted onto the outer wall of the aeration pipe.

[0007] Furthermore, the cleaning component includes a connecting frame located at the bottom of the collecting component, and a cleaning roller brush corresponding to the adjusting sleeve is rotatably mounted on the inner side of the connecting frame.

[0008] Furthermore, as a further improvement to this technical solution, several groups of aeration micropores are linearly arrayed on the outer wall of the aeration pipe, and each group of aeration micropores is arranged in a ring array on the outer wall at the bottom quarter circle of the aeration pipe.

[0009] Furthermore, since the aeration micropores are located on the outer wall of the aeration pipe, the air output and direction of the aeration micropores need to be adjusted according to the actual use to meet different sewage treatment conditions. The adjustment component also includes several air outlets that are linearly arrayed and correspond to the aeration micropores on one side of the outer wall of the adjustment sleeve, and several air nozzles that are linearly arrayed on the other side of the outer wall of the adjustment sleeve.

[0010] Furthermore, the inner wall of the regulating sleeve is fitted to the outer wall of the aeration pipe.

[0011] Furthermore, since the adjusting sleeve needs to be rotated for adjustment, power needs to be provided to the adjusting sleeve to ensure the accuracy of driving and adjustment. The driving assembly includes a protective ring fixedly installed on the side of the mounting bracket. A fixed gear ring is fixedly fitted on the outer wall of the adjusting sleeve located inside the protective ring. A drive motor is fixedly installed on the side of the protective ring. The output end of the drive motor passes through the inner wall of the protective ring and is fixedly fitted with a drive gear that meshes with the fixed gear ring.

[0012] Furthermore, a protective shell corresponding to the drive motor is fixedly installed on the side of the protective ring.

[0013] Furthermore, the photovoltaic panels are tilted, allowing rainwater to slide down them during cloudy or rainy weather. Cleaning the regulating sleeve requires water and driving force. The collection assembly includes a fixed plate mounted on the bottom of the photovoltaic panel. A water collection tank is located on the side of the fixed plate. Two guide openings are symmetrically opened on the side of the fixed plate. Two guide blocks that slide and connect with the guide openings are fixedly mounted on the side of the water collection tank. A spring is fixedly installed between the bottom surface of the guide blocks and the side of the fixed plate. Two rotating shafts are symmetrically rotatably mounted on the inner wall of the water collection tank. A support plate is fixedly fitted on the outer wall of each shaft. One end of the shaft passes through the side of the water collection tank and is fitted with a torsion spring. The two ends of the torsion spring are fixedly connected to the rotating shaft and the water collection tank, respectively.

[0014] Furthermore, sealing strips are installed on all four sides of the support plate.

[0015] The regulating sleeve is located in the sewage. Impurities in the sewage may adhere to the outer wall of the regulating sleeve and may block the air outlet and air nozzle. It needs to be cleaned daily to ensure normal operation. The cleaning component also includes a connecting pipe that runs through the bottom of the water collection tank. A drain box is installed through the outer wall of the connecting pipe. A shaft is rotatably installed on the inner wall of the connecting pipe. Several blades arranged in a linear array are fixedly installed on the outer wall of the shaft. The connecting frame is fixedly installed on the bottom surface of the drain box. One end of the shaft passes through the side of the connecting pipe and is connected to the cleaning roller brush through a driven wheel and a synchronous belt.

[0016] As a further improvement to this technical solution, the cross-sectional shape of the connecting pipe is circular, and the outer wall of the cleaning roller is provided with hard bristles.

[0017] Compared with the prior art, this application has the following beneficial effects:

[0018] 1. By driving the regulating sleeve to rotate on the outer wall of the aeration pipe through the drive component, the air volume and direction of the aeration micropores can be flexibly adjusted. When it is necessary to increase the air volume, more aeration micropores can be located in the air outlet. When it is necessary to change the air direction, the regulating sleeve is rotated to adjust the air outlet to the position of the corresponding aeration micropore. This adjustment method can accurately control the aeration effect according to different conditions of sewage treatment, such as local anoxic areas or specific pollution layers, improve oxygen utilization and treatment efficiency, and avoid local sludge deposition or short-circuiting. It can also be used for aeration and oxygenation in scenarios such as river management, landscape water body maintenance, aquaculture oxygenation, and high-fluctuation water level environments.

[0019] 2. The water collection tank initially collects rainwater through the support plate. As the amount of rainwater increases, the overall weight of the water collection tank increases and it slides downward. When a certain amount of rainwater is collected, the support plate rotates to allow the rainwater to fall to the bottom of the water collection tank. This design realizes automatic collection and drainage of rainwater without manual intervention, which improves the automation level of the device. At the same time, the collected rainwater can be reused later.

[0020] 3. As rainwater is collected and discharged from the water collection tank, the cleaning roller brush can be moved to the regulating sleeve. Under the action of rainwater impacting the blades and driving the shaft to rotate, the cleaning roller brush is driven to rotate through the driven wheel and synchronous belt. The hard bristles are used to clean the outer wall of the regulating sleeve. With the rotation of the regulating sleeve, the cleaning roller brush can ensure that the outer wall of the regulating sleeve is thoroughly cleaned, ensuring the air output efficiency of the aeration micropores during daily use. This method of using rainwater to drive cleaning not only saves energy, but also realizes the regular cleaning of the regulating sleeve, extending the service life of the device.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0043] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0044] like Figure 1-10 As shown, an aeration device includes a float 1, an aeration pipe 2 disposed on the outer side of the float 1, four photovoltaic panels 3 arranged in a ring array fixedly installed on the top surface of the float 1, a control box 4 corresponding to the aeration pipe 2 and photovoltaic panels 3 fixedly installed at the center of the top surface of the float 1, several sets of aeration micro-holes 5 arranged in a linear array on the four sides of the aeration pipe 2, and each set of aeration micro-holes 5 is arranged in a ring array on the outer wall of the bottom quarter circle of the aeration pipe 2, and adjustment components 6 for adjusting the direction and air volume of the aeration micro-holes 5 are disposed on the four sides of the aeration pipe 2, four sets of drive components 7 for driving the adjustment components 6 are disposed on the outer wall of the aeration pipe 2, and collection components 8 for collecting rainwater are disposed at the bottom of the four photovoltaic panels 3, and cleaning components 9 corresponding to the adjustment components 6 are disposed at the bottom of the four collection components 8.

[0045] During operation, the float 1 is first fixed in the sewage tank, and the photovoltaic panel 3 converts solar energy into electrical energy for the control box 4. The control box 4 drives the aeration pipe 2 and aerates the sewage through the aeration micropores 5 to increase the dissolved oxygen content in the sewage and promote the decomposition of organic matter by microorganisms, thereby achieving sewage purification. During the aeration process, the driving component 7 drives the regulating component 6 to adjust the aeration micropores 5, so that the air output and direction on the aeration pipe 2 can be adjusted according to the actual situation. At the same time, in rainy weather, the collection component 8 at the bottom of the photovoltaic panel 3 can collect rainwater, and the photovoltaic panel 3 can play the role of guiding liquid. When the rainwater is collected to a certain amount, the cleaning component 9 can be driven to clean the regulating component 6, so that the dirt on the regulating component 6 can be removed to avoid affecting the use of the aeration micropores 5. At the same time, the driving component 7 and the regulating component 6 need to cooperate to achieve a thorough cleaning of the regulating component 6.

[0046] For details, see Figure 3-5 As shown, since the aeration micropores 5 are located on the outer wall of the aeration pipe 2, the air output and direction of the aeration micropores 5 need to be adjusted according to the actual use to meet different sewage treatment conditions. The adjustment component 6 includes a mounting frame 61 symmetrically fixedly installed on the side of the float 1. An adjustment sleeve 62 is rotatably installed on the inner wall of the mounting frame 61, and the adjustment sleeve 62 is rotatably fitted onto the outer wall of the aeration pipe 2. The inner wall of the adjustment sleeve 62 is in contact with the outer wall of the aeration pipe 2. Several air outlets 63 corresponding to the aeration micropores 5 are opened on one side of the outer wall of the adjustment sleeve 62 in a linear array, and several air nozzles 64 are opened on the other side of the outer wall of the adjustment sleeve 62 in a linear array.

[0047] At work, such as Figure 4 In the state shown, each group of aeration micropores 5 is located in the air outlet 63, and all aeration micropores 5 can emit air at the maximum air output. When adjusting the air output, under the action of the drive component 7, the adjusting sleeve 62 can rotate on the outer wall of the aeration pipe 2. At this time, the number of aeration micropores 5 in the air outlet 63 can be adjusted, and the aeration micropores 5 can be blocked by the inner wall of the adjusting sleeve 62, thereby realizing the adjustment of the air output. When adjusting the air output direction, under the driving action of the drive component 7, the rotating adjusting sleeve 62 can adjust the air outlet 64 on the other side to the position corresponding to the aeration micropore 5. By adjusting the position of the air outlet 64, the air output of the aeration micropores 5 at different positions can be changed, thereby realizing the adjustment of the air output direction to cope with wastewater treatment under different conditions.

[0048] Among them, see Figure 5 and Figure 6As shown, since the adjusting sleeve 62 needs to be rotated for adjustment, in order to ensure the accuracy of the driving and adjustment of the adjusting sleeve 62, it is necessary to provide power to the adjusting sleeve 62. The driving assembly 7 includes a protective ring sleeve 71 fixedly installed on the side of the mounting bracket 61. A fixing gear ring 72 is fixedly fitted on the outer wall of the adjusting sleeve 62 located inside the protective ring sleeve 71. A drive motor 73 is fixedly installed on the side of the protective ring sleeve 71. The output end of the drive motor 73 passes through the inner wall of the protective ring sleeve 71 and is fixedly installed with a drive gear 74 that meshes with the fixing gear ring 72. A protective shell 75 corresponding to the drive motor 73 is fixedly installed on the side of the protective ring sleeve 71.

[0049] During operation, when adjusting the position of the air outlet 63 and air nozzle 64 on the adjusting sleeve 62, the drive motor 73 can be turned on through the control box 4. When the drive motor 73 drives the drive gear 74 to rotate, the drive gear 74 meshes with the fixed gear ring 72, which in turn drives the fixed gear ring 72 and the adjusting sleeve 62 to rotate, thereby realizing the adjustment of the position of the air outlet 63 and air nozzle 64.

[0050] See Figure 7-9 As shown, since the photovoltaic panel 3 is tilted, rainwater will slide down the photovoltaic panel 3 during rainy weather, and cleaning the regulating sleeve 62 requires water and driving force; therefore, the collection component 8 includes a fixed plate 81 fixedly installed at the bottom of the photovoltaic panel 3. A water collection tank 82 is provided on the side of the fixed plate 81. Two guide ports 83 are symmetrically opened on the side of the fixed plate 81. Two guide blocks 84 are fixedly installed on the side of the water collection tank 82 and slidably connected to the guide ports 83. A spring 85 is fixedly installed between the bottom surface of the guide block 84 and the side of the fixed plate 81. Two rotating shafts 86 are symmetrically rotatably installed on the inner wall of the water collection tank 82. A support plate 87 is fixedly fitted on the outer wall of each of the two rotating shafts 86. Sealing strips are provided on all four sides of the support plate 87. One end of the rotating shaft 86 passes through the side of the water collection tank 82 and is fitted with a torsion spring 88. The two ends of the torsion spring 88 are fixedly connected to the rotating shaft 86 and the water collection tank 82, respectively.

[0051] During operation, in rainy weather, rainwater can flow along the photovoltaic panel 3 into the water collection tank 82. Under the torsion of the torsion spring 88, the support plate 87 is initially in a horizontal position, and the initially collected rainwater is located above the support plate 87 in the water collection tank 82. As the rainwater is collected, the overall weight of the water collection tank 82 gradually increases. At this time, the water collection tank 82 can slide downward through the guide block 84 in the guide opening 83. When the rainwater in the water collection tank 82 reaches a certain amount, it can press the support plate 87, causing the support plate 87 to rotate through the rotating shaft 86. At this time, the collected rainwater can fall to the bottom of the water collection tank 82. After the rainwater passes through the support plate 87, the support plate 87 can be reset under the action of the torsion spring 88 so that it can be collected again. At the same time, under the action of the spring 85, the water collection tank 82 can be moved upward through the guide block 84 along the guide opening 83 to reset.

[0052] See Figure 9 and Figure 10 As shown, since the regulating sleeve 62 is located in the sewage, impurities in the sewage may adhere to the outer wall of the regulating sleeve 62, and the impurities may block the air outlet 63 and the air nozzle 64. Daily cleaning is required to ensure normal operation. The cleaning component 9 includes a connecting pipe 91 that runs through the bottom of the water collection tank 82. The connecting pipe 91 has a circular cross-section. The outer wall of the connecting pipe 91 is through which the drain tank 92 runs. The inner wall of the connecting pipe 91 is rotatably mounted with a shaft 93. The outer wall of the shaft 93 is fixedly mounted with several blades 94 arranged in a linear array. The bottom surface of the drain tank 92 is fixedly mounted with a connecting frame 95. The inner side of the connecting frame 95 is rotatably mounted with a cleaning roller brush 96, and the outer wall of the cleaning roller brush 96 is provided with hard bristles. One end of the shaft 93 passes through the side of the connecting pipe 91 and is connected to the cleaning roller brush 96 through a driven wheel and a synchronous belt.

[0053] During operation, as rainwater is collected in the water collection tank 82 and the tank moves downwards, the cleaning roller brush 96 can move from a position away from the adjusting sleeve 62 to the adjusting sleeve 62. As rainwater passes through the support plate 87, it enters the connecting pipe 91. The falling rainwater impacts the blades 94, causing the shaft 93 to rotate. The shaft 93 and the cleaning roller brush 96 are connected via a driven wheel and a synchronous belt drive. Therefore, the rotation of the shaft 93 drives the cleaning roller brush 96 to rotate, thereby cleaning the water. The hard bristles on the roller brush 96 clean the outer wall of the regulating sleeve 62. As rainwater is used, the water collection tank 82 moves upward, which drives the cleaning roller brush 96 to rotate and gradually move away from the regulating sleeve 62 to reset for reuse. At the same time, the drive motor 73 can be turned on during the cleaning process to drive the regulating sleeve 62 to rotate. Combined with the rinsing of rainwater, this ensures that the cleaning roller brush 96 can thoroughly clean the outer wall of the regulating sleeve 62, thus ensuring the air output efficiency of the aeration micropores 5 during daily use.

[0054] In summary, by driving the regulating sleeve 62 to rotate via the drive component 7, the air output and direction of the aeration micropores 5 can be flexibly adjusted to adapt to different wastewater treatment conditions, thereby improving oxygen utilization and treatment efficiency. On rainy days, rainwater flows into the water collection tank 82 through the photovoltaic panel 3, achieving automatic collection and drainage, improving the degree of automation and enabling resource reuse. During the rainwater collection and discharge process in the water collection tank 82, the rainwater impacts the blades 94, driving the cleaning roller brush 96 to rotate. In conjunction with the rotation of the regulating sleeve 62, the outer wall of the brush can be thoroughly cleaned, ensuring the air output efficiency of the aeration micropores 5. Furthermore, the use of rainwater to drive the cleaning process saves energy and extends the life of the device. The overall design is efficient and practical.
