ABSTRACT:
A magnetic drive system in a reactor generates rotational and translational motion of the agitator. The magnetic drive system includes a tubular shaft having one end attached to the agitator, and another end. A magnetic annular weight is fitted to the another end. A guide column has an end supported by the reactor body and a free end, the guide column further having a cylindrical bore in which an intermediate part of the tubular shaft slides in a fluid tight manner. A cylindrical guide cap is fluid tightly mounted to the free end of the guide column, the guide cap covering the magnetic annular weight and incorporating a cylindrical guide shaft integral with a bottom of the cap, the tubular shaft sliding coaxially and fluid tightly on the guide shaft. A drive rotor covers the guide cap and has another annular magnetic weight enclosing the guide cap and positioned with respect to the annular weight fitted to the tubular shaft such that a rotational or translational movement of the drive rotor generates a corresponding movement of a tubular shaft and the agitator. A motor is connected to the drive rotor for driving the rotor about an axis coaxial with the axis of the reactor body.
