The utility model discloses an inverted umbrella type composite aerator, which is connected by a motor and a reducer through transmission connectors, the output end of the reducer is connected with the upper end of the transmission rod, and the lower end of the transmission rod is connected with the impeller body. The impeller body is inverted umbrella-shaped, and the blade is radially fixed on the impeller body. The supporting surface of the impeller body is radially uniformly distributed with air intake holes, and the transmission rod above the The upper part is connected with the blades of the axial fan, and the circumference of the blades of the axial fan is distributed around the transmission rod. When the inverted umbrella compound aerator works, the motor drives the reducer to work, the reducer transfers power to the transmission rod, the transmission rod drives the impeller body to rotate, agitates sharply on the water surface, and continuously increases the oxygen enrichment of circulating water. On the one hand, oxygen in the air cooperates with microorganisms in water to oxidize organic matters, on the other hand, it increases dissolved oxygen in water to purify and improve sewage. Compared with the traditional surface aerator, it has the advantages of high efficiency and energy saving.

一种倒伞型复合曝气机
本技术属于污水处理设备领域,具体涉及一种倒伞型复合曝气机。
技术介绍
倒伞型复合曝气机是城市污水处理工程氧化沟使用的关键设备,传统的倒伞型复合曝气机的所有叶轮,其形状都象一把倒着打开的纸形雨伞,安装在氧化沟的水面,采用机械减速驱动旋转,靠叶轮上若干个叶片刮水推流挟裹空气靠氧气溶解水中氧化有机物,达到净水的目的。由于叶片只能将水推着旋转,叶片撞击水造成气泡碎裂,流向紊乱,当表面溶氧达到一定值后很难再提高,造成曝气效果不是很好,动力效率低,一般只能达到1.6-2.4kgO2/kWh,最高也只能达到2.5-2.6kgO2/kWh,使我国城市污水处理成本中的能耗费用居高不下。
