Abstract

The invention discloses a gas-liquid mechanical coupled agitator. The gas-liquid mechanical coupled agitator comprises an agitating cylinder, a rotating shaft, an agitating part and an air injection assembly; the agitating cylinder defines a stirring space, the rotating shaft is arranged in the stirring space, the agitating part is connected to the rotating shaft, the agitating part is used for stirring a fluid material put in the stirring space, and the air injection assembly is used for passing gas into the stirring space to stir the fluid material. According to the gas-liquid mechanical coupled agitator, by arranging the agitating part to stir the fluid material and the air injection assembly to pass gas into the stirring space to stir the fluid material, the effective combination of gas stirring and mechanical stirring can achieve the effect of chaotic stirring. In this way, it can solve the problem of excessive energy input in the process of mechanical stirring, and solve the problem of stirring blind areas in gas stirring, thus, the mixing efficiency in the stirring space is greatly improved, at the same time, the energy consumption of agitation is reduced.

Description

technical field [0001] The invention relates to the field of industrial production stirring equipment, in particular to a gas-liquid mechanical coupling stirring device. Background technique [0002] The mechanical stirring process is to use the rotation of the stirrer in the stirring tank to convert the mechanical energy of the stirring paddle into the kinetic energy of the fluid, so that the fluid can obtain a stable flow field, and transfer heat, mass and momentum while complex chemical reactions occur in the flow field , so as to achieve a thorough mixing process. The purpose of fluid mixing is to mix and couple a variety of fluids with each other, so the movement of the fluid during the mixing process is extremely complicated. Whether it is analyzing the performance of existing mixing equipment or designing new mixing equipment, it can be used as a reference basis only some experience Summarize. [0003] Gas agitation is a method of injecting air into a liquid to agit...
