ABSTRACT:
An improved rotating retort seal having integral bearings for aligning the retort seals relative the sealing surface on the rotating vessel portion of the retort. The sealing function and bearing or seal alignment function are separated to extend seal life and improve sealing. Radial alignment bearings and axial alignment bearings are provided for continually positioning the seal assembly housing during sealing surface nutation. The sealing elements, which are fixed relative to the alignment bearings, is thereby continually aligned and realigned in response to sealing surface nutations during retort rotation. The alignment bearings are extended radially outward from the seals on the sealing surface to prevent damage of the bearings by materials processed in the retort. A lubrication passageway is placed between the alignment bearings and seals to provide for common lubrication of both alignment bearings and seals.
