Aerating and oxygenating device

Abstract

The invention relates to an aerating and oxygenating device. In order to effectively solve the problems that the aerating and oxygenating device is relatively small in oxygenating range, high in energy consumption, low in power efficiency and non-uniform in aeration, the invention adopts the technical scheme as follows: the aerating and oxygenating device comprises a motor, a speed reducer, a centrifugal impeller and a floating body, wherein the motor is connected with the speed reducer; a supporting body inclined downwards is installed on the side surface of the speed reducer; the motor and the speed reducer are suspended on a water surface through the floating body installed at the lower part of the supporting body; the speed reducer is connected with an upper annular disc above the water surface through a fixing component at the lower part; the upper annular disc is connected with a lower annular disc below the water surface through a connecting rod at the lower part; the centrifugal impeller between the upper annular disc and the lower annular disc is installed at the lower end part of a rotating shaft at the lower part of the speed reducer; a plurality of blades are uniformly distributed at the lower part of the upper annular disc in the external circumferential direction; and a flow guiding barrel is arranged in the center of the lower part of the lower annular disc. The aerating and oxygenating device is novel, unique, simple and reasonable in structure, low in cost, uniform in aeration, low in energy consumption, high in power efficiency, convenient to install, maintain, repair and replace and good in using effect.

Description

technical field [0001] The invention relates to an aeration and oxygenation device for sewage treatment and aquaculture. Background technique [0002] Aeration equipment is very important for sewage treatment and aquaculture. In the aerobic biological treatment of sewage, microorganisms need sufficient oxygen to quickly and efficiently degrade organic matter in sewage, so various aeration devices are required to aerate and increase oxygen in sewage. The quality of the aeration device not only affects the effect of sewage biochemical treatment, but also directly affects the land occupation, investment and operation costs of the sewage treatment plant. For aquaculture, the breeding density is relatively high across the country at present, and a large number of cultured organisms will consume a large amount of oxygen in the water, resulting in hypoxia in the cultured water body. As a result, the cultured organisms will be prone to illness and even death. In addition, the phen...
