摘要： PROBLEM TO BE SOLVED: To efficiently carry out mixing under observation of the inside without forming a dead space by installing a magnetic coil with a star shape in the surrounding of the outside of a cylindrical container and rotating a tubular rotor in the container by permanent magnets and at the same time stirring the content of the container. SOLUTION: This stirring apparatus comprises a cylindrical pressure resistant container 1 and a rotor 3 of a ring or tubular member 2 is so installed in the container as to concentrically rotate. The rotor 3 has a large number of symmetrically arranged permanent magnets 5 and the magnetic pole faces are set to face inward and outward. The rotor 3 is moved by the permanent magnets 5 and a magnetic field to rotate the rotor is generated by a magnetic coil 9 arranged into a star shape in the surrounding of the container 1. Moreover, impellers for stirring are installed in the rotation magnetic field in the container 1. Using a reaction apparatus provided with such a stirring apparatus, satisfactory mixing can be carried out while the inside of the reaction apparatus being made observable for no dead space is formed.

摘要： A stirring system for a chemical reactor, particularly for operation at pressures of more than 5 bar, includes a magnetic coil (9) arranged in star formation outside the cylindrical reactor vessel (1) to generate a rotating magnetic field. A rotor (3) inside the vessel is provided with paddles and fitted with permanent magnets (5) which interact with the magnetic field.
