20080257511 | OUTLET DEVICE FOR A PRESSURIZED VESSEL HAVING A COMBINED RADIAL BEARING AND HYDRAULIC DRIVE MOTOR - 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. | 10-23-2008 |
20090142147 | MONITORING AND ADJUSTMENT SYSTEM AND METHOD FOR A HIGH PRESSURE FEEDER IN A CELLULOSE CHIP FEEDING SYSTEM FOR A CONTINUOUS DIGESTER - A method and computer controlled apparatus to control fluid leakage in a high pressure feeder and a stationary housing with a chamber in which rotates a pocket rotor. The method includes: monitoring the fluid leakage from the high pressure feeder, wherein the fluid leakage is discharged from a low pressure outlet of the high pressure feeder; determining whether the fluid leakage is within a predefined range of acceptable fluid leakage, and moving the pocket rotor in the chamber to adjust the fluid leakage. | 06-04-2009 |
20100155003 | CYLINDRICAL BEARING FOR PRESSURE DIFFUSER AND ASSOCIATED METHOD - A bearing cylinder for a screen assembly of a pressurized pulp diffuser, the bearing cylinder including: a plurality of segments of the bearing cylinder wherein the segments are arranged side-by-side to form the bearing cylinder; and each of said segments includes a first region formed of a hard material resistant to damage from sand and rocks, and a second region formed of a soft material that thermally expands and conforms to bearing surfaces opposite to the bearing cylinder. | 06-24-2010 |
20100266351 | UNOBSTRUCTED LOW PRESSURE OUTLET AND SCREEN GRID FOR A HIGH PRESSURE FEEDER - A rotary high pressure feeder for processing cellulosic fibrous material including: a rotor rotatable about an axis and comprising at least one pocket comprising a conduit extending through the rotor in a direction perpendicular to the axis and having end openings at opposite ends of the pocket, wherein each of said end openings of each pocket functions as both an inlet and outlet depending upon an angular position of the rotor within a housing; the housing encloses said rotor and said housing includes a low pressure inlet port and a low pressure outlet port aligned vertically, and a high pressure inlet port and a high pressure outlet port aligned horizontally, wherein the ports are arranged on the housing for registry with the end openings of at least one pocket, and a screen grid seated in or adjacent to the low pressure outlet port, wherein the screen grid includes an array of screen slots and bars forming a uniform pattern of slots and bars extending without interruption across an entirety of the low pressure outlet port. | 10-21-2010 |
20130206346 | FLASH TANK WITH ADJUSTABLE INLET AND METHOD FOR ADJUSTING INLET FLOW TO A FLASH TANK - A flash tank including: a closed interior chamber; a gas exhaust port coupled to an upper portion of the chamber; a liquid discharge port coupled to a lower portion of the chamber; an inlet nozzle attached to an inlet port of the chamber, wherein the inlet nozzle includes a flow passage, and a movable valve plate in the flow passage, wherein the valve plate has a first position which defines a first throat in the flow passage and a second position which defines a second throat having a smaller cross-sectional area than the first throat. | 08-15-2013 |
20140182802 | PRESSURE DIFFUSER WITH AN ANNULAR BAFFLE SCREEN PLATE OVER WATER INLET - A pressure diffuser washer comprising: an outer wall, an inner wall adjacent to the outer wall, the inner wall defining annular baffle chambers between the outer wall and the inner wall, wherein each of the annular baffle chambers is configured to connect to a source of a wash liquid, a reciprocating screen assembly adjacent to the inner wall, the reciprocating screen assembly defining a first annular chamber between the inner wall and the reciprocating screen assembly, an area in the inner wall defining a gap associated with each of the annular baffle chambers, wherein the wash liquid from an annular baffle chamber flows through the gap into the first annular chamber, and an annular baffle screen plate covering the gap, wherein the annular baffle screen plate defines openings sized to prevent rocks and other large particulate debris from entering the annular baffle chambers. | 07-03-2014 |
20150053362 | RETROFIT ASSEMBLY AND METHOD FOR INSTALLING A HYDRAULIC DRIVE MOTOR TO A PRESSURIZED VESSEL - A hydraulic drive assembly for a large pre-existing pressurized digester vessel and a method of installation of the hydraulic drive assembly have been conceived. Such a device includes a stub shaft which has a lower end and an upper end. The lower end engages with a hydraulic drive and the upper end is coupled to a drive shaft. The coupling further includes a top coupling and a bottom coupling. The top coupling is coupled to the drive shaft, and the bottom coupling is coupled to the stub shaft. A drive support bracket is attached to the hydraulic drive and then attached to the drive support bracket by at least one sole plate that is fixed to a foundation. The hydraulic drive assembly installation method is utilized when removing an electric motor and mechanical transmission device and replacing it with a hydraulic drive assembly. | 02-26-2015 |
