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.
A design method of bottom-entry magnetic stirring device, wherein the stirring device comprise an impeller assembly and an isolation sleeve, wherein the impeller assembly and the isolation sleeve are connected along an axial direction in a movable manner, the impeller assembly is capable of driving a material in the middle of a stirring tank to move downward, wherein the isolation sleeve is equipped with a limiting structure which is provided at an upper part of the impeller assembly and is capable of generating a magnetic force acting on the impeller assembly, wherein the magnetic force has a downward component which restricts the impeller assembly to be in a suspended state during stable rotation, the limiting structure comprises a first magnet, and a second magnet is provided on the impeller assembly, the first magnet and the second magnet are axially arranged by magnetic repulsion, and a magnetic force of the first magnet is set downward against the second magnet, wherein the isolation sleeve restricts the axial movement distance of the impeller assembly through the principle of magnetic levitation, and the impeller assembly is in a suspended state during rotating, wherein the design method comprises the following steps:
