Abstract
A design method of bottom-entry magnetic stirring device is disclosed in which the stirring device includes an impeller assembly and an isolation sleeve which are connected axially in a movable manner. The isolation sleeve restricts the axial movement distance of the impeller assembly through the principle of magnetic levitation. The impeller assembly is suitable for driving the material in the middle of the stirring tank to move downwards. The isolation sleeve is set with downward magnetic force towards the impeller assembly, and the impeller assembly is in a suspended state when rotating, satisfying the formula Fvi+Ff=G+Fc. Thus, in the case of known impeller thrust Fvi or repulsive force Fc between magnets, the repulsive force Fc between magnets or impeller thrust Fvi can be obtained, thereby obtaining the design parameters of the magnets and the rotating speed of the drive shaft when it rotates stably.
