Publication number: 20240115978Abstract: Disclosed herein are disc filters for dewatering a fiber suspension. According to a first aspect, the disc filter includes a vessel comprising an inlet positioned in a wall of the vessel, the inlet introducing a fiber suspension into the vessel. The disc filter further includes a rotor shaft comprising a shaft axis of rotation positioned in a shaft plane, wherein the shaft plane is a horizontal plane. At least one filter element may be coupled to the rotor shaft. At least one injector may be positioned in the wall of the vessel, the at least one injector introducing a secondary flow of liquid into the vessel. The at least one injector may be located in the wall of the vessel at an injector elevation angle ?I that is greater than ?44 degrees and less than or equal to +22 degrees relative to the shaft plane.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Applicant: Kadant Black Clawson LLCInventor: Hugues Dionne

Patent number: 8617357Abstract: A twin wire press for dewatering solid-liquid suspensions, such as pulp suspensions, between top and bottom webs is described herein which includes consecutive primary, secondary and tertiary dewatering sections. The primary dewatering section includes a wedge area. The secondary dewatering section is positioned adjacent to the primary section downstream therefrom and includes grooved rolls in an s-roll configuration. The tertiary dewatering section includes rolls in a scissor-nip configuration. The press rolls in the secondary and tertiary section are all supported onto a frame. Whenever maintenance is to be performed on any one of the grooved rolls or on the press roll assemblies, an overhead crane can for example be used since no frame structure is provided on top thereof.Type: GrantFiled: March 9, 2010Date of Patent: December 31, 2013Assignee: Kadant Canada Corp.Inventors: Hugues Dionne, Marc-André Hétu, Daniel Parenteau

Patent number: 6925929Abstract: A screw press provided with a rear excess fluid outlet is described herein. The rear excess fluid outlet includes a circular screen provided at a longitudinal end of the screw press body, near a material inlet. Scraper blade assemblies are provided to prevent the screen from clogging. The efficiency of excess fluid removal is thereby increased by the increased screen surface near the material inlet of the screw press.Type: GrantFiled: April 14, 2004Date of Patent: August 9, 2005Assignee: Advanced Fiber Technologies (AFT) TrustInventor: Hugues Dionne
