The beneficial effects of the utility model:
The impeller of the utility model aerator produces powerful negative pressure, seismic wave and rotary-cut power in the rotation of aeration chamber high speed, air is sucked air collecting chamber by inlet pipe, the air that enters air collecting chamber under the effect of seismic wave and rotary-cut power during through the qi-emitting hole of porous flinders and aeration chamber wall air bolus and air chain shredded, impeller cut, fragmentation, the mixing of rotating again through aeration chamber high speed, make it fully to be dissolved in the water, broken dramatically and disperseed air, significantly improved aeration efficient; Qi-emitting hole is dispersed throughout the air collecting chamber endless inner wall, makes inhaled air be rotated the cutting mixed aeration by the comprehensive supply impeller of 360 degree, also plays the effect that significantly improves inspiratory capacity and aeration efficient, and inspiratory capacity can reach 400～600m
3/ h does not need to be equipped with gas blower again, and the utilization ratio of oxygen can reach 60%～90%, has reached the purpose of giving the high oxygenation of pond water.Because the qi-emitting hole of porous flinders and aeration chamber wall to the preliminary fragmentation of air, has been saved power consumption, reduced working cost simultaneously.
The utility model motor places on the water surface, and aeration unit places under water, and motor housing is not had the requirement of high leakproofness, has reduced cost, has overcome simultaneously that the submersible machine fault is many, the life-span short, the defective of inconvenient maintenance.
Because the utility model aeration machine impeller is less, required rotating speed is higher during works better, generally more than 1000rpm, directly provide kinetic energy to get final product by frequency control motor or standard electromotor, do not need to dispose separately step-down gear, both reduced cost, overcome the defective of step-down gear inconvenient maintenance again.
The utility model aerator inlet pipe top is provided with air volume regulating valve, but Open valve is air-breathing by it when needing the oxygen supply aeration in aeration process, when needing anoxic or anaerobism in the water, just valve is turned off and stopped air feed and make impeller in water, carry out plug-flow and stirring in the running, reach the purpose of a tractor serves several purposes.
The utility model aerator is simple in structure, and volume is little, and equipment investment cost is low, is the key equipment that biochemical treatment is carried out in various industrial sewages and urban domestic wastewater.This equipment also can be used for the improvement of lake and city river sewage.
