  • Patent number: 8794821
    Abstract: A simple, robust and low-cost torsionally flexible, sealed drive that allows external drives to provide agitation within a container. A torsionally flexible tube is sealed to a torsionally rigid portion of a container. A second end of the tube is sealed to a driven element within the container. The driven element is coupled to a drive-shaft that is partly contained within the tube. Motion of the protruding end of the drive shaft imparts a corresponding motion to the driven element, while maintaining a water-tight seal between container and drive-shaft. One useful motion is a rotary oscillation. A stepper motor may operate via such a drive to impart a rotary oscillation to an impellor in a bioreactor, or mixing container, suitable for agitating a cell culture in a nutrient medium or hydrating a powdered media in water. The drive is suited to use in disposable bioreactors and mixers.

    Abstract: The invention relates to method for producing granules. Methods for producing granules are diversely used in chemical process engineering, for example, for producing starting materials for shaped bodies and, to be precise, for brake linings and sealing elements. The inventive method for producing granules from fibrous, powdery and liquid components in a mixing receptacle of a mixer provides that by rotating at least one mixing tool inside the mixing receptacle in a first direction of rotation, a compacting effect upon the components is achieved between the mixing tool and a wall section of the mixing receptacle. For example, this is achieved by appropriately sloped surfaces on the mixing tool, which push the components located inside the mixing receptacle toward a wall section. The inventive compacting effect enables an improved formation of granules. The mixer can be a conventional vertical mixer. The granulates have an advantageously rounded shape and size, for example, of the size of matchstick heads.

  • Patent number: 5611921
    Abstract: A process of dewatering primary-treated sewage which includes mixing the sewage with a coagulant or flocculant aid, usually activated polymer. The sewage is then mixed and flocculated at conditions which involve extensive mixing turbulence of the sewage and whereby part of the sewage is recycled so as to be again subjected to such mixing and flocculating. Flocks form the solid particles in the sewage. The pH of the sewage is chemically adjusted into the basic pH range or to a higher basic pH. The sewage is applied to a sand bed whereby the flocculated solids in the sewage are separated from the liquid in the sewage, by collecting on the top of the sand bed. The flocculated solids located on the top of the sand bed are air dried. The dried flocculated solids are removed from the top of the sand bed.

  • Patent number: 5261746
    Abstract: A method of transporting and processing a viscous slurry, mash, or insoluble in a liquid carrier wherein there is provided a container having a paddle system disposed therein, the paddle system configured to oscillate in a limited, back and forth fashion so as to lift and shift the fluid mass toward a center portion of the container interior via gravity, and to a bottom portion thereof for recirculation and blending. The method further includes a coupling piece connected to the paddle system, and a portable drive system, the method steps including transporting the container filled with the insoluble and liquid carrier, coupling the portable drive system to the coupling piece, and actuating the portable drive system for oscillating the paddle system via the coupling piece.

  • Patent number: 5248416
    Abstract: A sewage treatment system which presents a main flow line and a recirculating line, the former for flock which has appreciated in size due to the addition of a polymer and passage through an area of agitation/turbulence and the latter for the return of small sized flock to the agitator/turbulence area for size increase. The passageways of the system include movable flaps, serving recirculation purposes, and a ledge or flutter for current creation and flock build-up. Raw liquid sewage enters the system, where the outlet leads to a belt press and/or a dry bed to cake the resulting sludge.

  • Patent number: 4944600
    Abstract: Disclosed is an agitator apparatus for mixing tanked fluids while simultaneously wiping any adherent fluids from the tank wall. The device comprises a fluid agitating means rotationally mounted within the tank for mixing the fluid held therein. At least one tank wall wiper blade is attached to the fluid agitating means to skim or wipe fluid from the tank wall as rotational movement of the agitation means occurs. The agitation means may, in itself, comprise one or more perforated mixing panels attached to a rotating shaft member so as to effectively mix the fluid as the shaft member is rotated.

  • Patent number: 4767218
    Abstract: The present invention comprises a mixing paddle assembly which may be used with a variety of mixing devices, but which is especially useful with devices which include a motorized carriage adapted to move along a beam spaced above an elongate mixing vat. Depending from the carriage are a pair of shafts, and within the carriage a separate motor is adapted to move the shafts upwardly and downwardly as the carriage moves along the beam. The mixing paddles of the present invention are affixed to the end of such shafts. The improved paddle assemblies of the present invention include a pair of plastic blades mounted to a blade assembly which includes laterally extending, stationary pegs residing in arcuate slots of pivotably supported end plates, so that the blades may be freely rotated on supporting shafts to be angled differently on the forward and return passes of the paddles. The supporting shafts extend substantially normal to the axis of the respective depending shaft.
