Abstract
A seal-less immersible mixing system for agitating materials contained within a storage tank. The mixing system utilizes an induction motor to drive a drive shaft having an impeller. The mixing system also includes a plurality of magnetic non-contact bearings circumferentially located around a portion of the drive shaft. The magnetic bearings reduce periodic service requirements typically required of existing mixing systems using contact bearings. Elimination of mechanical seals further reduces periodic service requirements of existing mixing systems utilizing mechanical seals.
Claims12
A mixing system for agitating materials contained in a storage container, the mixing system comprising:
- a drive shaft having an impeller;
- a casing covering a portion of a length of said drive shaft;
- a plurality of non-contact bearings circumferentially located around a portion of said drive shaft within said casing, said plurality of non-contact bearings supporting said drive shaft within said casing;
- and
- means for rotating said drive shaft, rotation of said drive shaft causing movement of the impeller for agitating materials contained in the storage container.
A mixing system for agitating materials, the mixing system comprising:
- a storage container holding a liquid in an interior portion of said storage container;
- a drive shaft having an agitating means, said drive shaft being positioned within the interior portion of said storage container;
- a casing covering a portion of a length of said drive shaft;
- a plurality of non-contact bearings located around a portion of said drive shaft within said casing, said plurality of non-contact bearings aligning said drive shaft within said casing;
- and
- means for rotating said drive shaft, rotation of said drive shaft causing the agitating means to agitate the liquid held in the interior portion of said storage container.
