[0064] During cleaning, when the sewage treatment tank 1 is used for a long time, a large amount of dirt remains and adheres to the inner surfaces of the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5. At this time, the output shaft of the forward and reverse motor 13 drives the screw rod 11 to push the push block 21 to slide along the guide rail 10. After the push block 21 is moved to a suitable use position, the piston rod of the first cylinder 19 pushes the moving block 1402 to move.

The water in the clean water disinfection tank 6 is used as the cleaning medium, and the consumption of fresh water sources is reduced through recycling. At the same time, the environmental pollution and additional costs that may be caused by the use of chemical cleaning agents are avoided, thereby reducing the overall cleaning cost, reducing the accumulation of dirt on the inner wall of the tank body, and avoiding the corrosion and wear of the tank body structure and equipment by dirt, thereby extending the service life of the sewage treatment facility.

[0069] Working principle:

[0070] When in use, the sewage to be treated enters the regulating tank 3 from the water inlet trough 2, and is filtered through the grille 7 when passing through the water inlet trough 2, so that the dirt in the sewage is filtered, and the dirt in the sewage stays on the outer wall of one side of the grille 7, and falls into the arc groove 808 with gravity. At this time, one of the rotating shafts 804 is driven to rotate by the output shaft of the first servo motor 806, so that the rotating shaft 804 drives the corresponding arc block 805 and the rotating wheel 802 to rotate, and the rotating wheel 802 is frictionally transmitted to the conveyor belt 801, so that the conveyor belt 801 rotates and moves along the rotating wheel 802, and is frictionally transmitted to another rotating wheel 802 through the conveyor belt 801. The conveyor belt 801 drives multiple inclined cleaning blocks 807 to rotate synchronously, so that the inclined cleaning block 807 pushes the dirt inside the arc groove 808 to move, so that the inclined cleaning block 807 is separated from the arc groove 808, and the dirt slides along the inclined cleaning block 807 and falls into the inside of the discharging block 809 and is discharged to the outside;

[0071] As the rotating wheel 802 rotates, the arc block 805 is driven to rotate synchronously. The outer wall of the arc block 805 at the lower end slides with the outer wall of the grille 7, and the dirt remaining on the outer wall of the grille 7 is scraped off and cleaned, so that it falls into the arc groove 808, which facilitates the cleaning of the residual dirt blocked by the grille 7, reduces the influence of the dirt on the filtering effect of the grille 7, ensures the initial filtering quality of the sewage, and provides better conditions for subsequent treatment processes.

[0072] During backwashing, the hand wheel 20 is rotated to separate from the sewage treatment tank 1, and the grille 7 is pulled to slide and be taken out along the water inlet trough 2, so as to facilitate the replacement of the grille 7. When the grille 7 is used for a long time, while one of the rotating shafts 804 is rotated, the insert block 904 is driven to rotate through the slot 905 and the hexagon socket bolt 906, and the insert block 904 drives the connecting shaft 903 and the turntable 902 to rotate. At this time, the rotating turntable 902 drives the rocker arm 907 to rotate and move through the pin shaft, so that the turntable 902 drives the backwash block 901 to move synchronously through the pin shaft and the rocker arm 907, and the backwash block 901 drives the sleeve 909 and the flushing water inlet pipe 914 to move synchronously, and the backwash block 901 drives the U-shaped block 908 to slide along the water inlet trough 2, so that the backwash block 901 slides along the outer wall of the other side of the grille 7;

[0073] During the sliding process, the disinfected water in the clean water disinfection tank 6 is sucked into the delivery pipe 913 through the water pump 912 and then enters the telescopic hose 915. The water is delivered to the water storage tank 910 of the backwash block 901 through the flushing water inlet pipe 914 through the telescopic hose 915. The water is continuously delivered to increase the internal pressure of the water storage tank 910, and the water is squeezed and sprayed to the outside from the water outlet tank 911, so that the squeezed and sprayed water flushes the outer wall of the other side of the grille 7, thereby backwashing and cleaning the grille 7, cleaning the dirt on the grille 7, and improving the filtering effect of the grille 7. The backwash component 9 avoids the problem of reduced filtering efficiency and blockage caused by dirt accumulation, improves the cleaning efficiency and accuracy, reduces equipment damage and incomplete cleaning during cleaning, does not require additional energy consumption or chemicals, further reduces environmental pollution, conforms to the concept of environmental protection and energy saving, and helps to improve the stability and treatment efficiency of the entire sewage treatment system, ensuring that the effluent water quality meets the standard requirements.

[0074] During cleaning, when the sewage treatment tank 1 is used for a long time, a large amount of dirt remains and adheres to the inner surfaces of the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5. At this time, the output shaft of the forward and reverse motor 13 drives the screw rod 11 to push the push block 21 to slide along the guide rail 10. After the push block 21 is moved to a suitable use position, the piston rod of the first cylinder 19 pushes the moving block 1402 to move. At this time, the moving block 1402 slides along the push block 21 through the limit groove 1403 and slides to a suitable position. After the use position, the output shaft of the self-locking motor 1407 drives the rotating rod 1408 to rotate along the two brackets 1410. At this time, the rotating rod 1408 drives the gear 1409 to rotate synchronously, so that the gear 1409 is meshed and transmitted to the tooth groove 1406, pushing the lifting block 1405 to slide along the support block 1404, and moving the lifting block 1405 to a suitable use height, which facilitates the movement of the lifting block 1405 to different use positions and use heights, and provides favorable conditions for the movement of the cleaning component 14;

[0075] The first rotary cylinder 1411 is synchronously moved by the movement of the lifting block 1405, and the extension block 1412 is driven to rotate to a suitable use angle by the rotating table of the first rotary cylinder 1411, and then the connecting block 1414 is driven to rotate to a suitable angle by the rotating table of the second rotary cylinder 1413 on the extension block 1412, so that the circular cover 1415 is synchronously moved, and the rotating motor 1416, the cleaning scraper 1417 and the cleaning brush 1401 are driven to move synchronously, so that the cleaning scraper 1417 is in friction contact with the inner wall of the sewage treatment tank 1 to be cleaned, and at this time, a gap is left between the circular cover 1415 and the inner wall of the sewage treatment tank 1, and the cleaning scraper 1417 and the cleaning brush 1401 are driven to rotate by the output shaft of the rotating motor 1416, so that the cleaning brush 1401 scrapes the sludge on the inner surface of the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5;

[0076] The inner surface after scraping the sludge is cleaned by the cleaning scraper 1417 to ensure that the sludge and dirt on the inner surface of each tank body are fully and accurately cleaned, effectively avoiding the cleaning blind area, and realizing the targeted cleaning of key areas such as the preliminary filtration layer of the regulating tank 3, the biological reaction layer of the anaerobic tank 22, the aeration area of ​​the aerobic tank 4, and the sedimentation layer of the sludge sedimentation tank 5, thereby improving the cleaning effect. In the regulating tank 3 and the sludge sedimentation tank 5, the cleaning scraper can effectively scrape off the sludge accumulated at the bottom; while in the anaerobic tank 22 and the aerobic tank 4, the cleaning brush deeply cleans the attachments on the tank wall and the biofilm, realizes deep cleaning, removes the dirt attached to the tank wall and the bottom, reduces the impact of the dirt on the sewage treatment process, and thus improves the overall treatment efficiency and water quality standards;

[0077] After the water in the clean water disinfection tank 6 is transported to the inside of the delivery pipe 913 by the water pump 912, the electric control valve on the delivery pipe 913 is closed, and the electric control valve on the liquid inlet hose 1420 is opened, so that the water in the delivery pipe 913 enters the liquid inlet hose 1420 and is transported to the inside of the annular groove 1418 of the circular cover 1415, and is sprayed from the water spray hole 1419 to the inner surfaces of the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5 to be cleaned for flushing, and is cleaned with the cleaning brush 1401. After the cleaning is completed, the circular cover 1415 is driven by the first rotating cylinder 1411 and the second rotating cylinder 1413 to move the sludge pump 1421 to a suitable angle and position; the lifting block 1405 is moved to a suitable height, and the residual sludge and sewage in the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5 are sucked and discharged to the outside through the mud discharge hose 1422;

[0078] It is convenient to clean the inside of the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5, improves the cleaning efficiency, reduces the residual sludge in the regulating tank 3, the anaerobic tank 22, the aerobic tank 4 and the sludge sedimentation tank 5 during long-term use, effectively removes the sludge and dirt attached to the tank wall, and provides a cleaner environment for subsequent sewage treatment. The water in the clean water disinfection tank 6 is used as the cleaning medium, and the consumption of fresh water sources is reduced through recycling.
