Description
Technical Field
The utility model belongs to the technical field of environmental protection sewage treatment device, and relates to a sewage stirrer.
Background
The device can make liquid and gas medium implement convection and uniform mixing. 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. The power of the small-diameter high-rotation-speed stirrer is mainly consumed by turbulent pulsation, so that micromixing is facilitated. The scale-up of stirrers is a complex problem associated with the process, which has hitherto been extrapolated to industrial scale only by stepwise empirical scale-up, based on the scale-up criteria obtained.
The conventional solution to the problem of enhancing the stirring effect is to increase the diameter of the impeller to make the rotation range thereof larger. However, the impeller with the increased diameter is more prone to be entangled by impurities in the working environment, and the efficiency is reduced, and meanwhile, the increased diameter of the impeller means that the strength requirement on the blade is more strict. Another solution is to add a stirrer, but this is too cumbersome and is prone to many problems. Therefore, the problem that the stirring effect of the sewage stirrer is enhanced and needs to be solved urgently in the field of sewage stirrers is solved.
