Vertical liquid stirrer
Technical Field
The invention relates to the technical field of stirrers, in particular to a vertical liquid stirrer.
Background
Stirring is to make a certain circulation through a stirrer, so that gas, liquid and even suspended particles in the solution are uniformly mixed.
