Abstract
The invention provides a magnetic rotor. The magnetic rotor provided by the embodiment of the invention comprises a magneton body and comb-tooth-shaped blades; and the comb-tooth-shaped blades are arranged on the magnetic rotor body, each comb-tooth-shaped blade comprises a plurality of teeth which are arranged at intervals, the teeth are arranged at intervals along the periphery of the magnetic rotor body, and each tooth is arranged on the surface of the magnetic rotor body in the radial direction of the magnetic rotor body and extends in the direction away from the magnet body. When the magnetic rotor provided by the embodiment of the invention is applied to mixing liquids or two incompatible phases, the mixed liquid can be better dispersed.
Description
technical field [0001] The present application relates to the field of stirring, in particular to a magnetic rotor. Background technique [0002] In chemical production and scientific research experiments, liquid mixing or incompatible two-phase (such as solid-liquid, liquid-liquid, etc.) mixing and dispersion are often involved. The uniformity of mixing and dispersion directly affects the stability of the mixture system , heat transfer, mass transfer and reaction rates. When the existing magnetic rotor is used in liquid or incompatible two-phase mixing, the dispersibility and stability are not enough, and it cannot well meet the requirements of chemical production and scientific research experiments. Contents of the invention [0003] In view of the above problems, the embodiment of the present application provides a magnetic rotor, which can better disperse the mixed liquid when it is applied to liquid or incompatible two-phase mixing. [0004] An embodiment of the pre...
