Background

the stirrer is a device which forces the liquid and gas media to convect and mix uniformly. The type, size and speed of rotation of the stirrer all have an effect on the distribution of the stirring power between bulk flow and turbulent pulsation. In general, the power distribution of a turbine-type agitator is favorable for turbulent pulsation, while a propeller-type agitator is favorable for bulk flow. For the same type of stirrer, under the same power consumption condition, the power of the stirrer with large diameter and low rotating speed is mainly consumed in the overall flow, so that the macroscopic mixing is facilitated.

For the raw material at the bottom of the stirrer, in order to mix it uniformly, the prior art generally adopts two methods: one is that a pipeline is erected at the bottom of the stirrer, and the raw materials are conveyed to the top by a pump to be continuously stirred, so that the scheme has a complex integral structure and high cost, and is not beneficial to maintenance; another method is to provide a propeller blade or other curved blade directly in the stirrer, for example, in a circulation type stirrer provided in patent document CN104941486A, the bottom material is conveyed to the top by the blade, but the efficiency of upward conveyance is not high due to the influence of the liquid viscosity, and particularly in a large stirrer, the fluid is likely to flow and disperse in the radial or circumferential direction while moving upward, and thus a high conveying and stirring effect cannot be obtained.
