Abstract

The invention discloses a stirring aerator, which comprises a base, a support, a speed reducer, a motor, a combined rotation shaft, a turbine, an underwater bearing, supporting pieces and a ring pipe. The turbine also comprises a horn-shaped turbine body which is formed by setting a curve to rotate around any of central axial lines and of which the upper part is small and the lower part is large, more than three main blades which are arranged uniformly along the turbine body and more than three auxiliary blades which are arranged uniformly along the turbine body. The stirring aerator integrates functions of stirring and aeration, and has the advantage of dual purposes on one machine; moreover, equipment configuration can be simplified in engineering application, so that a large amount of equipment investment is saved; therefore, the stirring aerator has wide application prospect in sewage treatment projects.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a stirring aerator. Background technique [0002] In sewage treatment, agitation and aeration are two essential processes in the activated sludge process. The purpose of stirring and aeration is to promote the growth and reproduction of beneficial microorganisms in activated sludge, so as to achieve the purpose of decomposing organic substances such as COD and BOD in sewage. [0003] Although there are many types of stirring and aeration equipment used for sewage treatment, stirring and aeration are two independent equipments. In the same biological tank that needs stirring and aeration, a mixer and an aerator (device) need to be equipped at the same time. , and run separately. This will increase the number of equipment configurations, increase equipment investment and operation and maintenance costs. In view of the above-mentioned defects, it is necessary to design a stirring aerator. ...
