Description

Technical Field

[0001] This utility model relates to the field of aeration anti-clogging, and more specifically, it relates to a novel aeration anti-clogging device. Background Technology

[0002] Aeration discs are a key piece of equipment used to inject air into wastewater to promote the activity of microorganisms, thereby accelerating the decomposition and removal of organic matter. Traditional aeration disc designs typically include a fixed air outlet hood with multiple air outlets to evenly distribute compressed air into the wastewater. However, after prolonged use, these air outlets can become clogged due to the accumulation of suspended solid particles and biofilm in the wastewater, leading to a decrease in aeration efficiency.

[0003] The patent with publication number CN222821384U discloses an anti-clogging aeration disc for sewage treatment, including a chassis, a fixing ring, an air outlet hood, and an air inlet pipe. The fixing ring is set on the top of the chassis, and the air outlet hood is rotatably engaged with the inner ring surface of the fixing ring. The top surface of the air outlet hood is evenly provided with multiple rings of top air outlet push holes, and the side surface of the air outlet hood is evenly provided with several side air outlet push holes. The top of the fixing ring is equipped with an outer cross scraper that fits against the outer top surface and side surface of the air outlet hood, and an inner cross scraper that fits against the inner top surface and side surface of the air outlet hood is installed inside the chassis.

[0004] The anti-clogging aeration disc in the above solution can drive the movement of two scrapers by rotating the aeration disc to prevent blockage inside the top air outlet and side air outlet, thus ensuring the aeration efficiency of the aeration disc. However, after long-term use of the inner and outer cross scrapers, a large number of solid particles and biofilm will also adhere to the two scrapers, causing the two scrapers to lose their scraping effect, which in turn leads to a decrease in aeration efficiency.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a novel aeration anti-clogging device that can employ intermittent aeration during the aeration process. During intermittent aeration, the gas drives the drive component to rotate the cleaning rod to clean the upper side of the aeration disc. While the cleaning rod is cleaning the aeration disc 2, the cleaning component also cleans the cleaning rod, preventing solid particles and biofilm from adhering to the cleaning rod.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a novel aeration anti-clogging device includes a pipe body and an aeration disc detachably connected to the pipe body. A rotating rod is rotatably connected to the pipe body, and a cleaning rod is fixedly connected to the rotating rod. A driving component for driving the cleaning rod to rotate is provided on the rotating rod, and a cleaning component for removing debris from the cleaning rod is provided on the rotating rod.

[0008] The present invention is further configured such that: the driving assembly includes a baffle fixedly connected to the rotating rod and a torsion spring fixedly connected to one end of the baffle, the other end of the torsion spring being fixedly connected to the inner wall of the tube, and the torsion spring being sleeved on the rotating rod.

[0009] The present invention is further configured such that: the cleaning assembly includes a fixed rod fixedly connected to the rotating rod, a sliding block slidably connected to the fixed rod, and a cleaning block fixedly connected to one end of the sliding block; the cleaning block is slidably connected to the cleaning rod; and the tube body is provided with a control component for controlling the sliding of the cleaning block.

[0010] The present invention is further configured such that: the control component includes a positioning rod fixedly connected to the tube body and a connecting rod rotatably connected to the positioning rod, and the connecting rod is rotatably connected to the sliding block.

[0011] The present invention is further configured such that a spring is sleeved between the fixed rod and the sliding block.

[0012] The present invention is further configured such that the cleaning rod is inclined on both sides.

[0013] In summary, this utility model has the following beneficial effects: intermittent aeration can be used during the aeration process. During intermittent aeration, the gas will drive the baffle to rotate, and the baffle will then drive the cleaning rod to rotate to clean the upper side of the aeration disc. When the cleaning rod cleans the aeration disc 2, the cleaning block will clean the cleaning rod, avoiding the adhesion of solid particles and biofilm on the cleaning rod, which would affect the cleaning effect of the aeration disc.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] A novel aeration anti-clogging device, such as Figures 1-3As shown, the device includes a pipe body 1 and an aeration disc 2 detachably connected to the pipe body 1. A rotating rod 3 is rotatably connected to the pipe body 1, and a cleaning rod 4 is fixedly connected to the rotating rod 3. The rotating rod 3 is equipped with a drive assembly that drives the cleaning rod 4 to rotate, and a cleaning assembly for removing debris from the cleaning rod 4. The drive assembly includes a baffle 5 fixedly connected to the rotating rod 3 and a torsion spring 6 fixedly connected to one end of the baffle 5. The other end of the torsion spring 6 is fixedly connected to the inner wall of the pipe body 1. The torsion spring 6 is sleeved on the rotating rod 3. During intermittent aeration, gas passes through the pipe body 1 and impacts the baffle 5, which then rotates 90°. When the torsion spring 6 is in a deformed state, when the baffle 5 rotates, it will drive the rotating rod 3 and the cleaning rod 4 to rotate. When the cleaning rod 4 rotates, the bottom side of the cleaning rod 4 will contact the top side of the aeration disc 2, scraping off the solid particles and biofilm adhering to the top side of the aeration disc 2. Then, the intermittent aeration stops, and the gas no longer pushes the baffle 5. The torsion spring 6 will then reset, driving the baffle 5, rotating rod 3, and cleaning rod 4 to reset, ready for the next cleaning. When the cleaning rod 4 cleans the aeration disc 2, it will also drive the cleaning component to clean the cleaning rod 4 itself, avoiding the long-term use of the cleaning rod 4 with adhered solid particles and biofilm, which would affect the cleaning effect of the aeration disc 2.

[0020] like Figures 1-3 As shown, the cleaning assembly includes a fixed rod 7 fixedly connected to the rotating rod 3, a sliding block 8 slidably connected to the fixed rod 7, and a cleaning block 9 fixedly connected to one end of the sliding block 8. The cleaning block 9 is slidably connected to the cleaning rod 4. The tube body 1 is provided with a control component for controlling the sliding of the cleaning block 9. The control component includes a positioning rod 10 fixedly connected to the tube body 1 and a connecting rod 11 rotatably connected to the positioning rod 10. The connecting rod 11 is rotatably connected to the sliding block 8. When the cleaning rod 4 rotates, the connecting rod 11 will limit the position of the sliding block 8. Then the cleaning rod 4 continues to rotate, and the connecting rod 11... The cleaning block 9 will rotate on the positioning rod 10, and the sliding block 8 will also rotate on the connecting rod 11. Since the connecting rod 11 will restrict the position of the sliding block 8 and the cleaning block 9, the cleaning block 9 can only rotate around the positioning rod 10 with the connecting rod 11 as the radius. This allows the cleaning block 9 to gradually approach the rotating rod 3 to clean the cleaning rod 4. When the torsion spring 6 resets and drives the cleaning rod 4 to reset, the cleaning block 9 will also gradually move away from the rotating rod 3 to clean the cleaning rod 4 again. This cleans the solid particles and biofilm attached to the cleaning rod 4 and improves the cleaning effect of the cleaning rod 4.

[0021] like Figures 1-3As shown, a spring 12 is sleeved between the fixed rod 7 and the rotating rod 3 and the sliding block 8. When the cleaning block 9 gradually approaches the rotating rod 3 to clean the cleaning rod 4, the spring 12 will be squeezed by the cleaning block 9 and deformed. Then the cleaning rod 4 returns to its original position, and the cleaning block 9 gradually moves away from the rotating rod 3 to return to its original position. The spring 12 can make the cleaning block 9 return to its original position more smoothly and prevent the cleaning block 9 from getting stuck on the cleaning rod 4 when there is debris between the cleaning rod 4 and the cleaning block 9.

[0022] like Figures 1-3 As shown, the cleaning rod 4 is inclined on both sides, which can improve the cleaning effect of the cleaning rod 4.

[0023] Working principle: During intermittent aeration, gas passes through the pipe 1 and impacts the baffle 5, which then rotates 90°. At this time, the torsion spring 6 is in a deformed state. When the baffle 5 rotates, it drives the rotating rod 3 and the cleaning rod 4 to rotate. When the cleaning rod 4 rotates, its bottom side contacts the top side of the aeration disc 2, scraping off the solid particles and biofilm adhering to the top side of the aeration disc 2. While the cleaning rod 4 rotates, the connecting rod 11 restricts the position of the sliding block 8. As the cleaning rod 4 continues to rotate, the connecting rod 11 rotates on the positioning rod 10, and the sliding block 8 also rotates on the connecting rod 11. At this time, the connecting rod 11 will restrict the position of the sliding block 8 and the cleaning block 9, so that the cleaning block 9 can only rotate around the positioning rod 10 with the connecting rod 11 as the radius. In this way, the cleaning block 9 gradually approaches the rotating rod 3 to clean the cleaning rod 4. When the intermittent aeration stops, the gas no longer pushes the baffle 5, and the torsion spring 6 will reset, driving the baffle 5, rotating rod 3 and cleaning rod 4 to reset, in preparation for the next cleaning. When the cleaning rod 4 resets, the cleaning block 9 will also gradually move away from the rotating rod 3 to clean the cleaning rod 4 again, thereby cleaning the solid particles and biofilm attached to the cleaning rod 4 and improving the cleaning effect of the cleaning rod 4.
