[0067] The sealing mechanism 8 is used to seal the aeration holes on the aeration pipe 5 to prevent the aeration holes on the aeration pipe 5 from being blocked, thereby improving the quality and efficiency of aeration. The setting of the guide rail 6012 and the groove 806 can guide the sealing plate 801 and also limit the shaking of the sealing plate 801 during movement, thereby ensuring the normal operation of the sealing plate 801.

A through hole 6010 connected to the outer cylinder 607 is opened on the inner cylinder 608. The gas enters the inner cylinder 608 from the connecting pipe 7. The piston 609 moves downward under the action of the gas until the gas is input into the outer cylinder 607 from the through hole 6010, and the gas is discharged from the aeration holes on the aeration pipe 5.

[0071] In this embodiment, the piston 609 is slidably arranged in the inner cylinder 608, and the piston 609 is connected to the lifting rod 606.

[0073] When the piston 609 moves downward, the lifting rod 606 will be driven to move downward, and the downward movement of the lifting rod 606 will drive one end of the push-pull rod 605 to move downward. The downward movement of one end of the push-pull rod 605 will push the other end of the push-pull rod 605 to move outward. The outward movement of the other end of the push-pull rod 605 will push the limit block 604 to move outward. The limit block 604 moves outward and drives the sliding rod 602 to slide along the fixed block 603. The spring 601 is compressed when the limit block 604 moves outward. When the limit block 604 moves outward, the blocking plate 801 moves toward the middle of the aeration pipe 5 along the guide rail 6012 with the cooperation of the tension spring 809, the first rotating arm 805 and the second rotating arm 808, and the protrusion 802 also moves inward along the aeration hole on the aeration pipe 5. The protrusion 802 is drawn out of the aeration hole on the aeration pipe 5. The gas entering the aeration pipe 5 will be discharged from the aeration hole; after the gas input into the connecting pipe 7 is stopped, the spring 601 is reset to drive the limit block 604 to move toward the center position of the aeration pipe 5. While the limit block 604 moves, it will push one end of the push-pull rod 605 to move toward the middle of the aeration pipe 5, and the other end of the push-pull rod 605 will push the lifting rod 606 and the piston 609 to move upward. The piston 609 moves upward along the inner cylinder 608 to block the through hole 6010. While the limit block 604 moves toward the middle of the aeration pipe 5, it cooperates with the action of the wedge block 804 to open the blocking plate 801 outward, so that the protrusion 802 on the blocking plate 801 penetrates into the aeration hole on the aeration pipe 5, thereby achieving the purpose of blocking the aeration hole, preventing sewage from blocking the aeration hole on the aeration pipe 5, and ensuring the normal operation of the aeration pipe 5.

[0074] The driving mechanism 6 is used to drive the blocking plate 801 to move, so that the protrusion 802 on the blocking plate 801 penetrates into the aeration hole on the aeration pipe 5, thereby blocking the aeration pipe 5, ensuring the normal operation of the aeration pipe 5, and improving the aeration quality and efficiency.

[0075] like Fig.12 As shown, the present invention further provides a sewage treatment system 9, comprising the above-mentioned aeration device for sewage treatment.

[0076] The working process is as follows:

[0077] During operation, the gas supply device inputs gas into the inner cylinder 608 through the connecting pipe 7. After the gas reaches the inner cylinder 608, the piston 609 moves downward. The piston 609 moves downward until the gas in the inner cylinder 608 can be input into the outer cylinder 607 through the through hole 6010. At the same time, when the piston 609 moves downward, the lifting rod 606 moves downward. The downward movement of the lifting rod 606 drives one end of the push-pull rod 605 to move downward. The downward movement of one end of the push-pull rod 605 pushes the other end of the push-pull rod 605 to move outward. The outward movement of the other end of the push-pull rod 605 pushes the limit block 606. 04 moves outward, the limit block 604 moves outward to drive the sliding rod 602 to slide along the fixed block 603, and the spring 601 is compressed while the limit block 604 moves. When the limit block 604 moves outward, the blocking plate 801 moves toward the middle of the aeration pipe 5 along the guide rail 6012 under the cooperation of the tension spring 809, the first rotating arm 805 and the second rotating arm 808, and the protrusion 802 also moves inward along the aeration hole on the aeration pipe 5. The protrusion 802 is drawn out of the aeration hole on the aeration pipe 5, and the gas entering the aeration pipe 5 is discharged from the aeration hole, thereby achieving the purpose of aerating the sewage treatment;

[0078] When the height of the aeration pipe 5 needs to be adjusted, the piston rod of the lifting cylinder 201 is retracted to drive the lifting frame 205 to move upward, and the upward movement of the lifting frame 205 drives the aeration pipe 5 to move upward, thereby achieving the purpose of adjusting the height position of the aeration pipe 5, and improving the use scenario of the device;

[0079] When it is necessary to stir the sewage in the sewage treatment system 9, it is only necessary to turn on the first motor 301 to drive the first belt to rotate, the first pulley 305 drives the second pulley 303 to rotate through the belt 302, the second pulley 303 rotates to drive the lifting mechanism 2 to rotate, and the lifting mechanism 2 rotates to drive the aeration pipe 5 to rotate, so that the sewage can be stirred while aeration is achieved;

[0080] When it is necessary to adjust the aeration range of the aeration pipe 5 in the sewage treatment system 9, the second motor 401 is turned on to drive the threaded rod 403 to rotate. The rotation of the threaded rod 403 will drive the movable plate 502 to move along the mounting hole 404 on the adjustment plate 402 toward the side close to the vertical plate 202. When the movable plate 502 moves, one end of the aeration pipe 5 will move toward the side of the vertical plate 202, and the other end of the aeration pipe 5 will move toward the side away from the vertical plate 202. In conjunction with the action of the rotating mechanism 3, the aeration range of the device in the sewage treatment system 9 will be increased. During aeration, the sewage in the sewage treatment system 9 can also be stirred, thereby improving the quality and efficiency of aeration.

[0081] The above contents are merely examples and explanations of the structure of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the scope defined by the structure of the present invention, they shall all fall within the protection scope of the present invention.
