る。 Reference numeral 1 denotes a sewage tank for treating sewage, and a drive shaft 2 is rotatably attached to a motor 4 via a speed reducer or directly connected to the motor 4. This drive shaft 2 is made into a hollow shaft, and an air suction port 2a is bored in the upper part of the hollow shaft. Further, a stirring blade 3 is provided at the other end of the drive shaft to stir the dirty water. Next, an air pipe 5 is provided to cover the aeration device except for the stirring blade 3. One end of the air pipe 5 is inserted into the wastewater together with the stirring blade, and an outside air intake port 8 is provided at the other end. This outside air intake port 8 is directed downward so as to take in outside air from below, and the outside air intake port is made smaller in diameter than the air pipe 5. Then, a ball 9 is inserted into the joint between the outside air intake and the air pipe 5 as an opening/closing device for the air pipe so as to be able to move up and down, and a locking tool 10 for regulating the ball 9 is attached. Further, a branch pipe 6 is provided at an appropriate position of the air pipe 5 so that air is constantly blown into the air pipe. An air amount adjustment valve 7 is provided in the middle of the branch pipe, so that the amount of air can be adjusted.

い。 With the above-mentioned configuration, when the aerator is rotated by the motor 4, the stirring blades 3 rotate through the drive shaft, stirring the sewage, generating negative pressure, sucking air from the suction port, and discharging the sewage from the tip of the hollow drive shaft. blow air into. As the air in the air pipe is sucked in through the intake port, the ball installed at the intake port of the air pipe rises.
Take in outside air from the outside air intake. Also, air is constantly blown into the air pipe from the branch pipe 6. When the aerator is stopped, the air in the air pipe is not sucked in through the suction port of the drive shaft, so the ball 9 is not sucked in and falls down, blocking the outside air intake port. The air that is constantly blown into the air is not discharged to the outside air from the outside air intake port, but is sent into the aeration device, and is also blown into the drive shaft from the suction port of the drive shaft. Therefore, even if the bubbles try to move upward from the drive shaft in the dirty water, they cannot move because they are obstructed by the constantly blown air.
