The utility model has the advantages that the aerator main body of aeration stirrer is fixed compared with prior art
On the ground for the treatment of tank, the direction of rotation that can operate its upside motor adjusts sewage aerobic or anaerobic operation state in time
Switching.The periphery that stirring blade is covered at the top of cylinder is arranged in blowout/suction inlet tiltable in aeration stirrer
Portion, blowout/suction inlet angle can from horizontal direction/horizontal direction slightly up switch to diagonally downward.Starting aerobic operation
When, motor drive rotary shaft and stirring blade rotate it in one direction, and so that sewage in cylinder is generated upward water flow,
Sewage flow to below the cylinder horizontal direction/level slightly up blowout/the suction inlet in direction when, water (flow) direction from becoming water upwards
Slightly up, sewage disperses in air as fountain realizes dissolved oxygen to flat or level, finally drops back into water and completes aeration operation；
In anaerobic operation, motor drive rotary shaft and stirring blade rotate it in the reverse direction, so that blowout/suction inlet is by water
Square to the sewage that water surface inclined downward, flows into from blowout/suction inlet, from cylinder lower end, outflow ensures that air is not inhaled into again
In sewage, stirring operation is completed under the drive of stirring blade.
The utility model facilitates operator to realize the aerobic behaviour of aeration stirrer by the direction of rotation of control motor
Make with the switching of oxygen free operation, and without using mechanical lifting device in water, being switched over by simple mechanism can be with
Aerobic and oxygen free operation is executed, is executed simply, operation is easy.
