A Lifting Inverted Umbrella Surface Aerator

Abstract

The invention provides a lifting type inverted umbrella-shaped surface aeration machine. The lifting type inverted umbrella-shaped surface aeration machine comprises a motor, a shaft coupler, a lifting device, a speed-reducing box and a lifting type impeller. The motor is connected with the speed-reducing box through the shaft coupler; the lifting device is arranged below the speed-reducing box; an inverted umbrella base is arranged below the speed-reducing box; the upper end of an impeller shaft is connected with an inverted umbrella base key; the impeller shaft is in key connection with the inverted umbrella-shaped aeration machine; the lifting type impeller is arranged at the lower end of the impeller shaft; the lower end of the impeller shaft penetrates through a hub of the lifting type impeller, and is detachably connected with the lifting type impeller. The lifting type impeller enables water to be lifted along the impeller shaft, the water is thrown out by a high-speed rotating straight blade of the aeration machine in a low ejection line shape, water jump is caused and mixed with the air, and oxygenation is conducted; meanwhile, the lifting type impeller at the bottom of an oxidation ditch rotates to generate centrifugal push flow action, water is lifted and transported continuously, circumfluence is formed in an aeration pool, the gas liquid contact surface is updated, oxygen transfer is further conducted, and sewage in the oxidation ditch is completely aerated.

Description

technical field [0001] The invention belongs to the research field of environmental protection equipment, and in particular relates to a lifting type inverted umbrella type surface aerator. Background technique [0002] my country's water resources account for 6% of the world's water resources, ranking fourth in the world, but China has a large population and its water consumption ranks among the top in the world. On the road of continuous urbanization, water resources, as a basic natural resource, are decreasing day by day, and water pollution is becoming more and more serious. [0003] Adhering to the basic national policy of protecting the environment, in order to build a harmonious society between man and nature and promote the continuous progress of society, sewage treatment is the top priority. Therefore, increasing water pollution control is an urgent task at present. [0004] At present, most of the sewage treatment methods are activated sludge method. The key tech...

Problems solved by technology

[0007] The purpose of the present invention is to provide a deep-water oxidation ditch that is more suitable for the deep-water oxidation ditch compared with the prior art for the above-mentioned problem that the inverted umbrella impeller has no obvious lifting effect on the sewage and affects the aeration efficiency due to the deposition of deep-type oxidation ditch dirt. A lift-type inverted umbrella aerator that significantly increases the amount of oxygen in water, has high oxygenation efficiency, and has strong push-flow and agitation capabilities.
