Therefore, the present utility model is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in the present application.

[0025] Referring to Figures 1-3 , an aerated biological activated carbon filter tank, comprising a filter tank main body 1, the inner side wall of the filter tank main body 1 is fixedly connected with a filter box main body 2, the top of the filter box main body 2 is fixedly connected with a filter plate 3, a plurality of mounting holes 4 are formed through the top of the filter plate 3, the plurality of mounting holes 4 are evenly distributed on the top of the filter plate 3, the filter plate 3 is fixedly connected with a plurality of mounting boxes 5 through the plurality of mounting holes 4, a plurality of water inlets 6 are formed through the outer side walls of the plurality of mounting boxes 5, the plurality of water inlets 6 are linearly arrayed on the outer side walls of the plurality of mounting boxes 5, the inner side walls of the plurality of mounting boxes 5 are fixedly connected with activated carbon cylinders 8 respectively, the plurality of activated carbon cylinders 8 are respectively located inside the plurality of mounting boxes 5, and through holes are formed on the outer side walls of the plurality of activated carbon cylinders 8, the tops of the plurality of mounting boxes 5 are detachably connected with cover plates 9 respectively, a plurality of sliding grooves 10 are formed through the outer side walls of the plurality of cover plates 9, the plurality of sliding grooves 10 are respectively located at the middle positions of the tops of the plurality of cover plates 9, the plurality of cover plates 9 are respectively slidably connected with sliding rods 11 through the plurality of sliding grooves 10, the outer side walls of the tops of the plurality of cover plates 9 are respectively rotatably connected with threaded rods 12, the outer side walls of the plurality of threaded rods 12 are respectively threadedly connected with the inner side walls of the plurality of sliding rods 11, the bottoms of the plurality of sliding rods 11 are fixedly connected with clamping pieces 13 respectively, the plurality of clamping pieces 13 are all arc-shaped, which is convenient for fixing the activated carbon rods, avoiding the activated carbon rods from shaking under the influence of aeration during use, and thus avoiding the breakage of the activated carbon rods;

[0026] Taking one group of parts as an example, during use, remove the cover plate 9, then place the activated carbon rod in the middle of the two clamping pieces 13, and rotate the threaded rod 12. The threaded rod 12 adjusts the positions of the two sliding rods 11. The thread directions on the two sliding rods 11 are opposite. When the threaded rod 12 rotates, the two sliding rods 11 will move in opposite directions. Thus, under the push of the sliding rods 11, the two clamping pieces 13 clamp and fix the activated carbon rod. Further, place the activated carbon rod inside the activated carbon cylinder 8, and fix the cover plate 9 on the top of the installation box 5. When the inside of the filter tank main body 1 is aerated, the airflow drives the sewage to roll. During the rolling process, the sewage will enter the inside of the installation box 5 along the water inlet 6, and further enter the inside of the activated carbon cylinder 8 through the through holes on the outer side wall of the activated carbon cylinder 8. The activated carbon filters the sewage and adsorbs impurities, thereby purifying the sewage.

[0027] Refer to Figure 1 , the inner bottom wall of the filter tank main body 1 is rotatably connected with first adjusting rods 17. There are two first adjusting rods 17, and the two first adjusting rods 17 are symmetrically distributed with respect to the central axis plane of the filter tank main body 1. The outer side walls of the two first adjusting rods 17 are respectively threadedly connected with the inner side walls of the filter box main body 2. The tops of the two first adjusting rods 17 are fixedly connected with secondary gears 18. The inner bottom wall of the filter tank main body 1 is fixedly connected with second adjusting rods 20. There are two second adjusting rods 20, and the two second adjusting rods 20 are symmetrically distributed with respect to the central axis plane of the filter tank main body 1. And the two first adjusting rods 17 and the two second adjusting rods 20 are respectively located at both ends of the filter tank main body 1. The outer side walls of the two first adjusting rods 17 are respectively drivingly connected with belts 19. The two first adjusting rods 17 are respectively drivingly connected with the two second adjusting rods 20 through two belts 19;

[0028] During use, rotate the first adjusting rod 17. The first adjusting rod 17 drives the belt 19, and then drives the second adjusting rod 20 to rotate. Since the first adjusting rod 17 and the second adjusting rod 20 are respectively threadedly connected with the inner side walls of the filter box main body 2, when the first adjusting rod 17 and the second adjusting rod 20 rotate, they will drive the filter box main body 2 to be adjusted in height, thus facilitating the staff to maintain the filter box main body 2.

[0029] Refer to Figure 3 , the outer side wall of the installation box 5 is fixedly connected with blocking covers 7. There are multiple blocking covers 7, and the positions of the multiple blocking covers 7 correspond to the positions of the multiple water inlets 6 one by one, and the multiple blocking covers 7 are respectively located above the multiple water inlets 6. When the inside of the filter tank main body 1 is aerated, the sewage rolls with the aeration. During the rolling process, it is blocked by the multiple blocking covers 7, and then enters the inside of the installation box 5 and the activated carbon cylinder 8 along the water inlet 6 more quickly, thereby improving the filtration efficiency.

[0030] Refer to Figure 1, an installation frame 14 is fixedly connected to the outer side wall of the filter tank main body 1. There are two installation frames 14, and the two installation frames 14 are respectively located on the outer side walls of both sides of the filter tank main body 1. The inner side walls of the two installation frames 14 are both fixedly connected with motors 15. The two motors 15 are respectively connected to an external power supply. The output ends of the two motors 15 are both fixedly connected with main gears 16. The outer side walls of the two main gears 16 are respectively meshed with the outer side walls of two sub-gears 18;

[0031] Driven by the two motors 15, the two main gears 16 rotate. Further, the two first adjustment rods 17 and the sub-gears 18 are driven by the two main gears 16 to rotate, which can greatly reduce the physical exertion of the staff.

[0032] Refer to Figure 1 and Figure 4 , a water distribution tank 21 is fixedly connected to the outer side wall of the filter tank main body 1. The water distribution tank 21 is convenient for uniformly mixing the sewage entering the filter tank within a certain short period of time, improving the filtration efficiency. The bottom of the water distribution tank 21 is communicated with the inside of the filter tank main body 1. The uniformly mixed sewage enters the inside of the filter tank main body 1 along the bottom of the water distribution tank 21 and waits for filtration and purification.

[0033] Refer to Figure 1 and Figure 4 , an air pump main body 22 is fixedly connected to the outer side wall of the filter tank main body 1. The air pump main body 22 is connected to an external power supply. The output end of the air pump main body 22 is fixedly connected with an air inlet pipe 23. A spray head 24 is fixedly connected to the outer side wall of the air inlet pipe 23. When the air pump main body 22 is started, the air pump main body 22 conveys external oxygen into the inside of the filter tank main body 1, so as to maintain sufficient dissolved oxygen in the filter tank main body 1 and maintain the high activity of the biofilm in the filter tank main body 1.

[0034] Working principle:

[0035] For the aerated biological activated carbon filter, rotate the first adjusting rod 17. The first adjusting rod 17 drives the belt 19, which in turn drives the second adjusting rod 20 to rotate. Since the first adjusting rod 17 and the second adjusting rod 20 are respectively threadedly connected to the inner side wall of the filter cartridge body 2, when the first adjusting rod 17 and the second adjusting rod 20 rotate, they will drive the filter cartridge body 2 to adjust in height. When the entire filter cartridge body 2 is displaced to the outside of the filter tank body 1, remove the cover plate 9, and then place the activated carbon rod in the middle of the two clamping pieces 13. Rotate the threaded rod 12 to adjust the positions of the two sliding rods 11. The thread directions provided on the two sliding rods 11 are opposite. When the threaded rod 12 rotates, the two sliding rods 11 will move in opposite directions. Thus, under the push of the sliding rods 11, the two clamping pieces 13 clamp and fix the activated carbon rod. Further, place the activated carbon rod inside the activated carbon cylinder 8, and fix the cover plate 9 on the top of the installation box 5. When aeration occurs inside the filter tank body 1, the airflow drives the sewage to roll. During the rolling process, the sewage will enter the inside of the installation box 5 along the water inlet 6, and further enter the inside of the activated carbon cylinder 8 through the through holes on the outer side wall of the activated carbon cylinder 8. The activated carbon filters the sewage and adsorbs impurities, thereby purifying the sewage. Further, release and store the mixed sewage in the water distribution tank 21 inside the filter tank body 1. Start the air pump body 22, and the air pump body 22 transports the external oxygen into the filter tank body 1, maintaining sufficient dissolved oxygen in the filter tank body 1 and maintaining the high activity of the biofilm inside the filter tank body 1, thereby improving the filtration efficiency inside the filter tank body 1.
