Method Of Treating Material In A Continuous Digester

View page
US Patent:
6375796, Apr 23, 2002
Filed:
Aug 18, 2000
Appl. No.:
09/640666
Inventors:
Jay K. Sheerer - Hudson Falls NY
Joseph R. Phillips - Queensbury NY
Jerry R. Johanson - San Luis Obispo CA
John Pietrangelo - Queensbury NY
Assignee:
Andritz Inc. - Glens Falls NY
International Classification:
D21C 700
US Classification:
162 19, 162 17, 162237, 162251, 162248, 162243
Abstract:
A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a top, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter-changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0. 5-10Â to the vertical, and preferably substantially continuous. Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface (that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.

US Patent:
RE39208, Aug 1, 2006
Filed:
Apr 22, 2004
Appl. No.:
10/829477
Inventors:
Jay K. Sheerer - Queensbury NY, US
Joseph R. Phillips - Glens Falls NY, US
Jerry R. Johanson - San Luis Obispo CA, US
John Pietrangelo - Queensbury NY, US

D21C 7/00

Variable Stage Pressure Diffuser

View page
US Patent:
55672795, Oct 22, 1996
Filed:
Dec 2, 1991
Appl. No.:
7/801651
Inventors:
Joseph R. Phillips - Glens Falls NY
John D. Weston - Glens Falls NY
Victor L. Bilodeau - Glens Falls NY
Ronald G. Bain - Glens Falls NY
Mark D. Barrett - Glens Falls NY
Brian F. Greenwood - Glens Falls NY
John Pietrangelo - Glens Falls NY
Assignee:
Ahlstrom Machinery Inc. - Glens Falls NY
International Classification:
D21C 904
US Classification:
162232
Abstract:
Located within the annular screen of the pressure diffuser is a tubular baffle hung from adjacent the top of the vessel. The baffle has two headers disposed on its inner surface, with openings in the tube providing communication between the exterior of the tube and the headers. A conduit extends from each header to an arm at the top of the vessel, to allow extracted liquid to be discharged. Another extraction conduit is provided at the bottom of the vessel, in communication with the screen interior and the tubular baffle interior. Treatment liquid, such as wash liquid, may be introduced at two, three, or more positions along the vessel with the liquid extracted from the first and second headers being introduceable at different positions along the vessel. A flexible, elastomeric material, sealing element with integral annular skirt may extend from the bottom end of the tubular baffle and engage the screen to provide a seal minimizing mixing between stages.

Tapered Screen Assembly For A Cellulose Pulp Digester

US Patent:
61298166, Oct 10, 2000
Filed:
Oct 24, 1997
Appl. No.:
8/953880
Inventors:
Jay K. Sheerer - Hudson Falls NY
Joseph R. Phillips - Queensbury NY
Jerry R. Johanson - San Luis Obispo CA
John Pietrangelo - Queensbury NY
Assignee:
Andritz-Ahlstrom Inc. - Glens Falls NY
International Classification:
D21C 700
D21C 326
D21C 714
US Classification:
162237
Abstract:
A comminuted cellulosic fibrous material treatment vessel assembly includes a substantially vertical vessel having a top, bottom, and outlet, and through which the material flows in a flow direction. The vessel preferably has a substantially cylindrical wall with at least one diameter-changing transition between the inlet and the outlet. A screen assembly is preferably provided at or just past the transition. The screen assembly comprises one or more annular screen surfaces diverging in the flow direction of the material, the angle of divergence being between about 0. 5-10. degree. to the vertical, and preferably substantially continuous. Providing such a screen assembly reduces the radial compression of material thereon, and increases the volume and rate of liquid that can flow through the material and be removed through the screen surface compared to a non-diverging screen surface (that is a right-cylindrical surface). The screen surface has openings of substantially uniform size, and preferably with a substantially uniform percentage of open area, in the flow path.

Chip Feed System

View page
US Patent:
56179758, Apr 8, 1997
Filed:
Jul 27, 1995
Appl. No.:
8/507980
Inventors:
Jerry R. Johanson - San Luis Obispo CA
Victor L. Bilodeau - Queensbury NY
Mark D. Barrett - Queensbury NY
John Pietrangelo - Queensbury NY
Assignee:
Ahlstrom Machinery Inc. - Glens Falls NY
International Classification:
B67D 506
US Classification:
2221851
Abstract:
A chip bin construction, ideally suited for bins having a maximum diameter of twelve feet or more, uniformly discharges chips, after steaming, without the necessity of a vibratory discharge. A hollow transition portion is provided between a hollow substantially right circular cylindrical main body and a rectangular discharge. The hollow transition may have a substantially circular cross-section open top and a substantially rectangular cross-section open bottom and opposite non-vertical gradually tapering side walls. At least one feed screw may be mounted at the open bottom of the transition for cooperation with the discharge, and the feed screw(s)--or the equivalent--may provide for metering of the chips. Alternatively, the hollow transition portion may provide one dimensional convergence and side relief, and no screw feeders need be provided, in which case a conventional chip meter is used.
