[0038] When the reciprocating gear 314 rotates one full circle, it drives the connecting arm 315 to form a reciprocating lifting motion. When the connecting arm 315 descends, it drives the lifting frame 316 to descend, and through the lifting frame 316, it drives the lifting frame 317 to descend. Through the lifting frame 317, it drives the aeration cylinder 1 to descend between the fixed air cylinder 301 and the fixed water cylinder 303, so that the aeration pipe 206 performs aeration while also performing a lifting motion.

[0039] On other levels, this embodiment also provides a rotating mechanism 4 for rapid air intake and rapid water intake, as Figure 2 、 Figure 4 and Figure 5 shown. The rotating mechanism 4 includes a rotating shaft 405, and the rotating shaft 405 is arranged in the middle inside the aeration cylinder 1.

[0040] In this embodiment, as Figure 4 and Figure 5 shown, the rotating mechanism 4 includes a fixed frame 401, a fourth drive shaft 402, a shaft key 403, an air intake fan 404, a keyway 406, and a water intake fan 407. The fixed frame 401 is fixedly installed inside the fixed air cylinder 301. The top end of the fourth drive shaft 402 is movably installed in the middle of the fixed frame 401. The top end of the fourth drive shaft 402 is fixedly connected to the bottom end of the second drive shaft 309. The shaft key 403 is arranged on the side wall of the fourth drive shaft 402. The air intake fan 404 is fixedly sleeved on the top end of the fourth drive shaft 402. The middle of the rotating shaft 405 is movably installed in the middle of the air distribution plate 203.

The water intake fan 407 is fixedly installed at the bottom end of the rotating shaft 405;

[0041] By driving the air intake fan 404 to rotate, the gas entering the fixed air cylinder 301 from the connecting cylinder 302 is pressurized and introduced into the intake pipe 201, and the sludge mixed in the sewage is quickly dispersed by the rotation of the water intake fan 407, so as to facilitate the uniform mixing of the sludge and the sewage.

[0042] Working principle: When the present invention is in use, the dual-axis motor 307 is started. The second drive shaft 309 is driven to rotate by the dual-axis motor 307, and the fourth drive shaft 402 is driven to rotate by the second drive shaft 309. When the fourth drive shaft 402 rotates, the rotating shaft 405 is driven to rotate by inserting the shaft key 403 into the keyway 406. When the fourth drive shaft 402 rotates, the intake fan 404 is driven to rotate, so that the gas entering the fixed air cylinder 301 from the connecting cylinder 302 is pressurized and introduced into the intake pipe 201. When the rotating shaft 405 rotates, the water intake fan 407 is driven to rotate, so that the sewage entering the intake pipe 202 from the bottom end of the fixed water cylinder 303 quickly enters the aeration cylinder 1, and the sludge mixed in the sewage is quickly dispersed by the rotation of the water intake fan 407, so as to facilitate the uniform mixing of the sludge and the sewage;

[0043] The gas entering the intake pipe 201 first enters the air distribution chamber, and then is guided to the air inlet 207 through the air guide chamber 204 in the air distribution chamber, so that it enters the aeration pipe 206. The sewage mixed evenly in the intake pipe 202 enters the water distribution chamber, and then enters the aeration pipe 206 from the water inlet 208, so that the sewage entering the aeration cylinder 1 is discharged from the aeration pipe 206 simultaneously with the gas, thereby realizing jet bubble aeration;

[0044] After the dual-axis motor 307 is started, the first drive shaft 308 drives the first bevel gear 310 to rotate. When the first bevel gear 310 rotates, the third drive shaft 311 is driven to rotate by the second bevel gear 312. The single-tooth gear 313 is driven to rotate by the third drive shaft 311. Each time the single-tooth gear 313 rotates one circle, the reciprocating gear 314 is driven to rotate once. Each time the reciprocating gear 314 rotates one circle, the connecting arm 315 forms a reciprocating lifting motion once. When the connecting arm 315 descends, the lifting frame 316 is driven to descend. The lifting frame 316 drives the lifting frame 317 to descend, and the lifting frame 317 drives the aeration cylinder 1 to descend between the fixed air cylinder 301 and the fixed water cylinder 303, so that the aeration pipe 206 performs aeration while also performing a lifting motion, increasing the aeration area, improving the aeration effect, and improving the sewage treatment effect.
