During the use of the high-speed disperser, the feeding height and the insertion depth of the dispersing disc should be properly adjusted according to the viscosity of the material to be treated and the rotational speed of the dispersing shaft. When the dispersing disc rotates at high speed, a deep vortex will be formed on the surface of the material, and it is necessary to prevent the material from overflowing from the edge of the stirring tank. Here is a description of the configuration and installation of the high-speed disperser's dispersing plate.
There is a reasonable ratio between the diameter of the dispersing disc and the diameter of the stirring vessel, and its purpose is to make the material circulate well. Even with the same high peripheral speed, in general, the effect of a small impeller is less than that of a large impeller. However, the power consumed by the large impeller is much larger than that of the small impeller, because the stirring power is proportional to the fifth power of the impeller diameter and the cube of the rotational speed. In order to make the circulation good, there is generally no baffle plate in the stirring container, and there should be no dead angle, so the dish-shaped bottom is better.
Generally, the impeller of the high-speed disperser should be placed in the center of the stirring vessel, because from a purely mechanical point of view, the shaft offset operation will bring additional load to the shaft and increase power consumption, but from the perspective of chemical technology See, the proper offset of the shaft is a good thing, it is beneficial to improve the dispersion efficiency, it can also prevent the liquid from swirl, reduce the vortex depth, and improve the circulation effect. The distance of the shaft offset should not be too large, generally not more than 2 times the diameter of the shaft, as long as the operation is not affected.
