The invention discloses a magnetic coupling stirrer capable of cleaning and sterilizing. The magnetic coupling stirrer comprises a stirring shaft, wherein one end of the stirring shaft is fixedly connected with a driven rotor; the stirring shaft is supported by a bearing base; a cleaning and sterilizing cavity is formed between the stirring shaft and the inner wall of the bearing base; a driven rotor is arranged in an isolation sleeve; the isolation sleeve and the bearing base form a seal cavity body so as to isolate the driven rotor and the stirring shaft as well as the bearing from the exterior of equipment; a driving rotor is arranged at the outer side of the isolation sleeve; clearances are respectively formed between the side wall of the isolation sleeve as well as the side surfaces of the driving rotor and the driven rotor; magnetic steel is respectively arranged at the inner ring of the driving rotor and the outer ring of the driven rotor; the magnetic steel of the inner ring of the driving rotor corresponds to the magnetic steel of the outer ring of the driven rotor. The magnetic coupling stirrer capable of cleaning and sterilizing is especially suitable for occasions which need high-torque stirring, is simple in structure, very simple and convenient to maintain and install, and relatively low in cost.
Description
technical field [0001] The invention relates to a stirring device, in particular to a magnetic coupling stirring device capable of realizing cleaning and sterilization. Background technique [0002] The existing washable and sterilizable radially coupled magnetic stirring device requires a specially designed drive motor and speed controller (such as Chinese utility model patent ZL201220667687.0), and the manufacturing cost is relatively high in applications requiring large torque. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a magnetic coupling stirring device capable of cleaning and sterilizing, which can ensure the effect of cleaning and sterilizing by using a conventional drive motor and a conventional frequency converter. [0004] In order to solve the above-mentioned technical problems, the technical solution of the magnetic coupling stirring device capable of cleaning and sterilizing in the present inven...
