摘要
PURPOSE: Provided is an underwater aerator, in which the oxygen transfer ratio and the aeration power efficiency are improved; it is possible to prevent the aeration ability from fast and suddenly dropping when the aerator tilts; and the aeration capacity and the diffusion function for realizing an intermittent aerator are improved. CONSTITUTION: The underwater aerator, in which the diffusion function is improved, comprises a number of rotors(3) arranged in a driving shaft(2) of a driving motor(1); and a diffuser(4) positioned at the lower part of the rotors. The diffuser(4) is a cylinder shape or head-cut conical shape having an internal space. The upper part of the diffuser(4) is tightly closed and the lower part where the end of the air sending pipe(6) is inserted is opened, thereby forming a round-shaped air sending device. The side of the diffuser(4) is provided with a side air ejecting opening(41); and a ring-shaped lower air ejecting opening(42) is formed between a lower part of the diffuser(4) and the casing(5).
