The output shaft end of motor 17 connects turntable 16, and 16 place plane of turntable is parallel with 24 place plane of annular backup pad, turntable 16
Side connect transmission shaft 15, transmission shaft 15 by shaft connection drive rod 14, drive rod 14 can on transmission shaft 15 along
Shaft rotation, one end of drive rod 14 are connect with the side of air collecting box body 12, and the side of air collecting box body 12 is connected to vent hose 11,
It being connected to inside one end of vent hose 11 with inside the air outlet of blower 10, the lower part side of oxygenation slot 23 is connected to feed pipe 22,
Feed pipe 22 is connected to O grades of biological treatment tanks 4, and the lower part other side of oxygenation slot 23 is connected to discharge nozzle 21, discharge nozzle 21 and multistage
Filter device 6 is connected to.
The invention patent is additionally arranged dial type oxygen-increasing device on oxygenation slot 23, and dial type oxygen-increasing device can think oxygenation
Sewage is stirred by stirring pipe 18 while sewage inside slot 23 is passed through air, the air exported due to stirring pipe 18
It can gradually be flowed up inside sewage, stirring pipe 18 can generate during stirring between sewage and stirring pipe 18 can be square
Just the conveyor zones that gas passes through, so that the gas for allowing 18 delivery outlet of stirring pipe to export can pass through from non-densified regions, to allow
Air can be improved more fully aerobic inside sewage with waste water to improve the oxygen content inside sewage
Breath bacteria is in solid-liquid combination state since the sludge concentration inside arrival oxygenation slot 23 is higher to the processing speed of sewage,
Therefore when stirring pipe 18 is stirred sewage, the region positioned at 18 direction of advance rear of stirring pipe is due to the smaller meeting shape of pressure
At conveyor zones, gas is facilitated to pass through.The motor 17 of the invention patent can pass through transmission shaft 15, turntable 16 and drive rod 14
In conjunction with the horizontal sliding on annular backup pad 24 of air collecting box body 12 is driven, so that stirring pipe 18 be allowed to realize that the stirring to sewage is imitated
Fruit.Being combined by air collecting box body 12 with stirring pipe 18 for the invention patent, enables the air-flow of blower to imported into from the top down
In sewage inside oxygenation slot 23, the dirt inside stirring pipe 18 will be constantly blocked in so as to combine using air pressure and gravity
Water dredging, avoids stirring pipe 18 easily by sludge blockage, relative to the ventilation pipe being embedded in inside oxygenation slot 23, blocking
Risk substantially reduces.The drive rod 14, transmission shaft 15 and turntable 16 of the invention patent are steel structure, are carried out in stirring pipe 18
The phenomenon that being not in bending during stirring.
The top of the air collecting box body 12 is installed by booster fan 13, the shell of booster fan 13 and the shell of air collecting box body 12
