Abstract
An outlet device and motor assembly for a pressured vessel is disclosed, where the assembly includes: a generally vertical drive shaft extending below and through the vessel and coupled to a rotating mechanism within the vessel; a stationary outlet housing supporting the drive shaft; a thrust bearing mounted on the outlet housing and around the drive shaft to rotationally engage the drive shaft; a hydraulic drive coupled to rotationally drive the drive shaft, and a radial bearing mounted around the drive shaft to rotationally engage the drive shaft and said radial bearing is at or below the hydraulic drive.

An outlet device and motor assembly for a pressured vessel comprising:
- a generally vertical drive shaft extending below and through the vessel and coupled to a rotating mechanism within the vessel;
- a stationary outlet housing supporting the drive shaft;
- a thrust bearing mounted on the outlet housing and around the drive shaft to rotationally engage the drive shaft;
- a hydraulic drive coupled to rotationally drive the drive shaft, and
- a radial bearing mounted around the drive shaft to rotationally engage the drive shaft and said radial bearing is at or below the hydraulic drive.
An outlet device and motor assembly for a pressured vessel comprising:
- a generally vertical drive shaft extending below and through the vessel and coupled to a rotating mechanism within the vessel;
- a stationary outlet housing supporting the drive shaft;
- a thrust bearing mounted on the outlet housing and around the drive shaft to rotationally engage the drive shaft, and
- a hydraulic drive coupled to rotationally drive the drive shaft, wherein the hydraulic drive further comprises a radial bearing which supports the drive shaft.
A shaft outlet assembly and drive assembly for a digester comprising:
- a rotatable shaft extending from the outlet assembly into a pressurized vessel of the digester;
- a stationary outlet housing supporting the drive shaft;
- a thrust bearing mounted in the outlet housing and around the drive shaft to rotationally engage the drive shaft, and
- a hydraulic drive coupled to rotationally drive the drive shaft, wherein the hydraulic drive includes a radial bearing which supports the drive shaft.
A method for supporting and driving a drive shaft of a digester, wherein the digester has a drive shaft extending through a bottom header and the drive shaft is supported by an outlet device attached to the bottom header, said method comprising:
- a. adsorbing radial and axial forces applied by the digester to the drive shaft with a bearing in the outlet device;
- b. rotationally driving the drive shaft with a hydraulic drive assembly connected to the drive shaft and fixed to the outlet device, and
- c. adsorbing radial forces acting on the drive shaft with the hydraulic drive assembly.
