On the opposite sides of the rotary stirring shaft are mounted an upper vertical flat blade and first inclined flat blades opposite to each other. A first vertical flat blade has a sweptback blade associated therewith, and is mounted to the stirring shaft at a position under the first inclined flat blades, and a second inclined flat blade or blades and a second vertical flat blade having an associated sweptback blade are mounted to the stirring shaft at a position under the upper vertical flat blade. When the stirring shaft rotates, ascending flows of liquid to be processed along the inner wall within a vessel are generated by the upper vertical flat blade and the first and second vertical flat blades that are each associated with a sweptback blade. Descending flows of the liquid to be processed are generated by the inclined flat blades, thereby enhancing the mixing performance.Type: GrantFiled: October 11, 1994Date of Patent: December 5, 1995Assignee: Mitsubishi Jukogyo Kabushiki KaishaInventors: Takayoshi Kawaoka, Hiroaki Ogasawara, Kenichiro Nakamura, Takafumi Shimada, Setsuo Omoto

Patent number: 5466334Abstract: Methods for mixing a treatment agent with a pulp suspension are disclosed including supplying the pulp suspension to a mixing chamber, moving the pulp suspension through a mixing zone with the mixing chamber, supplying the treatment agent to the moving pulp suspension across the entire width of the mixing chamber prior to the mixing zone, and in which the height of the mixing zone is sufficiently small such that the pulp suspension and the treatment agent are subjected to kneading within the mixing zone in order to repeatedly stretch and compress fiber flocks in the pulp suspension. Apparatus for mixing the treatment agent with the pulp suspension are also disclosed.Type: GrantFiled: February 28, 1994Date of Patent: November 14, 1995Assignee: Sunds Defibrator Industries AktiebolagInventors: Borje Fredriksson, Kjell Forslund

Patent number: 5450368Abstract: A mixer capable of mixing a resin material consisting of a plurality of liquids and of discharging the mixture. The mixer includes a plurality of agitating portions provided on a rotor shaft, and a plurality of partitioning members disposed in a mixing chamber with the rotor shaft accommodated therein, for respectively partitioning each space defined between adjacent ones of the agitating portions. A gap between the agitating portion and the partitioning member is set to be small, and the partitioning members are provided with small holes. The material which is fed toward a discharging end through the small holes is consecutively cut by the agitating portions, and the liquid resin material can be mixed at low rotational speed.Type: GrantFiled: December 28, 1993Date of Patent: September 12, 1995Assignee: Three Bond Co., Ltd.Inventor: Yosimichi Kubota

Patent number: 5409313Abstract: An apparatus for deagglomerating powder in a mixture of liquid and powder. This apparatus contains a mixing tank, an agitator disk disposed within the mixing tank, and a baffle. The agitator disc has a maximum dimension of from about 6 to about 40 inches. The disc contains a multiplicity of compound teeth radially and removably attached its perimeter. Each of the compound teeth is comprised of a substrate to which is attached a front plate which preferably consists of a ceramic material, such as tungsten carbide.Type: GrantFiled: March 7, 1994Date of Patent: April 25, 1995Inventor: James E. Funk

Patent number: 5378321Abstract: Medium consistency (e.g. about 5-18%) paper pulp is mixed with a treatment fluid by fluidizing them while subjecting them to a constantly changing shear field in radial and axial planes. This is accomplished by providing a mixer rotor having a constantly varying cross-section along a dimension of elongation. The rotor may comprise a body having an external surface simulating alternately oriented cone frustums along its axis of rotation, with vanes connected to the external surface and including portions following the surface contour. A disk may or may not be provided at the end of the body connected to a shaft. A first interior housing portion has a configuration mimicking that of the rotor, while a second housing portion defines a fluidization zone with the disk.Type: GrantFiled: September 1, 1993Date of Patent: January 3, 1995Assignee: Kamyr, Inc.Inventor: Thomas R. Delcourt

Patent number: 5362146Abstract: A plastifying extruder of the double-screw type, to avoid dead zones in the flow, has at its throttle location throttle disks on the screws formed with outwardly open recesses angularly equispaced on the disks. Pins distributed around the screws in the throttle region project radially into gaps between the disks and can penetrate to a greater or lesser extent into these gaps to provide a variable flow cross section.Type: GrantFiled: March 14, 1994Date of Patent: November 8, 1994Assignee: Friedrich Theysohn GmbHInventor: Alfred Nogossek

Patent number: 5358329Abstract: An apparatus for mixing plural flowable materials, for example liquids, is disclosed having a disk-shaped rotor connected to a rotating drive shaft and housed in a cylindrical chamber. The rotor has engraved on one or both faces a spiral-shaped groove to provide sufficient mixing turbulence and prevent unmixed solute from exiting the chamber. The chamber is defined by walls of two stationary end plates separated by an outer cylindrical barrel. When configured in multiple stages having a plurality of rotors connected with a single rotating drive shaft and housed in a plurality of axially arranged such chambers, a centrally-drilled passage intervening between chambers connects adjacent chambers. Additional solvent liquid is introduced at each mixing stage through a radially drilled passage. The materials to be mixed are confined to a narrow interstice between the rotor, adjacent walls and barrel, and pass in sequence from one chamber to the next.Type: GrantFiled: February 12, 1993Date of Patent: October 25, 1994Assignee: Fluid Dynamics, Inc.Inventors: Paul R. Plache, Martin W. Selch
