Description

technical field [0001] The invention relates to a stirring device driven by magnetic force, which belongs to the field of mechanical mixing. Background technique [0002] Stirring device is a device for forced convection and uniform mixing of liquid and gaseous media. The type, size and speed of the stirrer have an effect on the distribution of the stirring power between the bulk flow and the turbulent pulsations. At present, various types of agitators are commonly used in industry and laboratories. Selecting a suitable agitator according to parameters such as the viscosity of the material can achieve better processing or experimental results. However, the stirring device commonly used in the current application is that the driving device drives the rotating shaft to rotate through the mechanical transmission method, and the stirring blade on the rotating shaft realizes the stirring of the material. The stirring blades are connected by mechanical transmission, so it has a ...
