The present invention utilizes high magnetic flux materials to substantially increase the power which can be transmitted from a magnetic driver, disposed outside of a vessel containing a fluid being processed, to a magnetically responsive agitator means disposed inside the vessel. This invention now enables the agitation, e.g., mixing, blending, etc., of fluids processed in the pharmaceutical, chemical and food processing industries, where relatively high torques are encountered, by non-contaminating magnetic drive means heretofore precluded in such applications. Means for producing vibrational agitation, and for reducing wear of the internal agitator bearing are also disclosed. |

DETAILED DESCRIPTION The present invention is adapted to magnetically drive a configuration of fluid agitating impellers located within, and typically at the bottom of, a vessel, vat or tank in which a fluid is being processed.
It is particularly suited for use in application which require the transmission of up to 3-4 horsepower of power to the impellers.
The invention comprises (i) a driver member, located external to the vessel, and having disposed within it an array of high energy product permanent magnets in a particular spaced and poled relation to one another; (ii) means for rotating the driver member, typically an electric motor; (iii) means for supporting the driver member and said rotating means; and (iv) a driven member located within the vessel and having disposed therein an array of high energy product permanent magnets in a particular spaced and poled relation to one another, and further, having disposed thereon impellers of a particular shape, size, and pitch.
The driven member is rotatably or otherwise supported on the bearing affixed to vessel bottom.
In one embodiment, a vessel plate is welded into the vessel bottom, which plate has a vertically disposed bearing on its side internal to the vessel and a flange extending downwardly on its external side.
The bearing rotatably supports the driven member, whereas the flange provides the means for supporting the driver member and the rotation (motor) means from the vessel.
In a second embodiment, useful in applications in which the vessel cannot be cut into in order to accommodate a vessel plate, the internally located bearing means, which rotatably supports the driven member, is held in place, in proper alignment with the axis of rotation of the driver member, by magnetic means.
Thus, it is a principal objective of the present invention to provide a means for magnetically transmitting relatively high power to agitation means immersed in a process fluid.
It is another principal object of this invention to provide, in high torque and r
