Description

Technical Field

[0001] This utility model relates to the field of sewage treatment pond technology, and in particular to a high-efficiency circulating biological oxidation pond. Background Technology

[0002] Wastewater has significant negative impacts on the environment, human health, economic development, and ecosystems. It may contain numerous pathogens such as bacteria, viruses, and parasites. If these pathogens enter the human body through drinking water, food, or contact, they can cause various diseases, such as cholera, typhoid fever, dysentery, and hepatitis, seriously threatening human health. Therefore, wastewater treatment is crucial. Circulating biological oxidation ponds are commonly used for wastewater treatment. These ponds are specialized wastewater treatment devices that primarily utilize microorganisms in activated sludge to decompose organic matter in wastewater under aerobic conditions, thus purifying the wastewater. They offer advantages such as high treatment efficiency, stable operation, and small footprint, effectively removing pollutants such as organic matter and ammonia nitrogen from wastewater.

[0003] Wastewater typically contains a large amount of impurities and suspended solids, such as leaves, plastic fragments, branches, and stones. These impurities can cause blockages in the pipes, pumps, aerators, decanters, and other equipment in the treatment tank, affecting their normal operation and even causing damage. Therefore, filters are usually installed in biological oxidation tanks to block impurities and prevent equipment damage. When a lot of impurities accumulate on the filter screen, it will affect the filtration effect and easily cause blockages. As a result, the filter screen needs to be cleaned manually and regularly to prevent blockages. This results in high labor costs, and the manual cleaning process is complicated and inefficient.

A motor 6 is fixedly connected to the upper end of the support column 2, and the motor 6 is electrically connected to an external power source. The output end of the motor 6 is fixedly connected to the threaded rod 5. A filter frame 7 is slidably connected to the inner surface of the tank body 1, and a filter 8 is provided inside the filter frame 7. A first connecting block 9 is fixedly connected to the upper surface of the filter frame 7, and a support rod 10 is rotatably connected to the inner surface of the first connecting block 9. A connecting frame 11 is fixedly connected to the upper end of the support rod 10. The side surface of the support column 2 is slidably connected to the connecting frame 11. The two sides of the frame 11 are fixedly connected to the first slider 4. The upper surface of the filter frame 7 is fixedly connected to the second connecting block 12. The inside of the second connecting block 12 is rotatably connected to the connecting rod 13. There are two connecting rods 13, which are distributed left and right. The inside of the connecting frame 11 is provided with the second sliding groove 14. There are two second sliding grooves 14, which are distributed left and right. The inner surface of the second sliding groove 14 is slidably connected to the second slider 15. The inside of the second slider 15 is rotatably connected to the connecting rod 13. The front end of the second slider 15 is fixedly connected to the pull rod 16. The inside of the connecting frame 11 is slidably connected to the pull rod 16. The outer surface of the pull rod 16 is provided with the spring 17. The front end of the spring 17 is fixedly connected to the front inner wall of the second sliding groove 14.

[0024] Working principle: When a large amount of impurities accumulate on the filter screen 8, the motor 6 is started. The motor 6 drives the threaded rod 5 to rotate, which in turn drives the first slider 4 to slide. The sliding of the first slider 4 drives the connecting frame 11 to slide, which in turn drives the support rod 10 to slide. The support rod 10 drives the first connecting block 9 to slide, which in turn drives the filter screen frame 7 to rise and fall. The filter screen frame 7 then drives the filter screen 8 to slide, controlling the height of the filter screen frame 7 above the upper surface of the pool body 1. Then, the handle 18 is pulled, which drives the pull rod 16 to slide, simultaneously compressing the spring 17. The pull rod 16 then drives the second slider 15 to slide, which in turn... When the position of the second slider 15 changes, the connecting rod 13 rotates. The rotation of the connecting rod 13 pulls the second connecting block 12 to change its position, thus rotating around the intersection of the support rod 10 and the first connecting block 9. This controls the tilt of the filter frame 7, and the impurities on the filter frame 7 roll under their own gravity and fall into the collection trough 19, so that workers can collect and process the impurities. After the impurities on the surface of the filter screen 8 are cleaned, the pull rod 16 is released, and the spring 17 loses its tension, causing the second slider 15 to slide to the bottom of the second slide groove 14, thereby causing the filter frame 7 to return to its original position.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
