Efficient aeration device for promoting oxygen dissolution

Abstract

The invention provides an efficient aeration device for promoting oxygen dissolution. A plurality of jet pipes communicated with a mixing chamber are mounted on a mixing cylinder; a stirring mechanism is arranged in the mixing chamber; the stirring mechanism comprises a rotary table and a plurality of stirring shafts connected with the rotary table; central axes of the stirring shafts are parallel to the central axis of the rotary table; a plurality of stirring assemblies are axially arranged on outer peripheries of the stirring shafts at intervals; a first end of a rotating shaft penetrates through a driven gear, stretches into the mixing chamber, is fixedly connected with the rotary table and penetrates through the rotary table; the rotating shaft is rotationally connected with the mixing cylinder and is fixedly connected with the driven gear; the rotary table can be rotated with the rotation of the rotating shaft; a sewage suction opening is formed in a first end of a water diversion pipe; a second end of the water diversion pipe stretches into the mixing chamber; a submersible pump is arranged on the water diversion pipe; an aeration mechanism comprises an air pump and an air guide pipe; a first end of the air guide pipe is connected with the air pump; the second end of the air guide pipe stretches into the mixing chamber; a plurality of air nozzles are axially arranged on the outer periphery of the air guide pipe at intervals. The efficient aeration device provided by the inventio is high in air aeration efficiency and good in sewage oxygenation effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an efficient aeration device for promoting oxygen dissolution. Background technique [0002] In the process of sewage aerobic treatment, it is necessary to use the aerator to supply oxygen to the sewage. There are many types of aerators, including microporous aeration, mesopore aeration, surface aerator aeration, rotary brush aeration and jet aeration, etc. A form of aeration. As a conventional aeration product, the jet aerator has the advantages of long service life, simple maintenance, and convenient installation. However, most of the jet aerators on the market currently have low oxygen dissolution efficiency and insufficient liquid-gas mixing. , resulting in a low oxygen absorption rate, which ultimately leads to unsatisfactory or substandard sewage treatment effects. Contents of the invention [0003] Based on the technical problems in the background technology, ...
