  • Patent number: 8074810
    Abstract: Apparatus and methods provide individual blades driven by drives configured to reduce a tendency of sludge to be moved in an undesired return direction. Drive configurations apply “pull” and “pull” forces that only pull on tensile structures, avoiding a need in actual commercial practice for use of extra structural drive members having high resistance to both tension and compressive forces exerted parallel to a sludge movement direction. Each of two separate tensile structures carries one blade, or a separate set of blades, with blade(s) of one structure adjacent to, and alternating with, blade(s) of the other structure. Embodiments move sludge from a corner of a basin and across a floor of the basin. The reduced tendency of sludge movement in the return direction results from moving one tensile structure and blade(s) in the sludge movement direction as the other tensile structure and adjacent opposed blade(s) move in the return direction.

  • Patent number: 7393456
    Abstract: A new settlement tank and its associated method of operation. The settlement tank has side surfaces and a bottom surface that define a tank of a predetermined volume. A trough is disposed in the bottom surface of the tank. At least one outlet port communicates with the trough. A press assembly is provided that includes a press head and an actuator for selectively advancing the press head into the trough. In operation, the settlement tank is filled with material that includes liquids and solids. The heavy solids are permitted to settle at the bottom of the tank.

  • Patent number: 6641724
    Abstract: The invention relates to a device and a method for chemically and physically separating solid materials from a suspension using flotation. A rotationally symmetrical flocculation/flow reactor is provided with outlets in the lower part thereof and is arranged in a separating tank. At least one suspension inlet extends eccentrically into said reactor. The supplied suspension is guided into said reactor. The supplied suspension is guided into the upper area of the flocculation reactor via the suspension inlet. A circular flow is thus created which drains off from the flocculation reactor downwards in a tangential and radial manner over the outer circumference into circularly arranged distribution cells which reinforce the tangential component of the suspension flow when said flow is delivered into the separating tank. In prior art, the flow of the mixture consisting of the suspension and air-sacs extends radially outwards.

  • Patent number: 6607666
    Abstract: A mud tank cleaning system includes a debris collection sweep that drives debris towards a collection zone in a mud tank, whence the debris can easily be mechanically disposed of through an opening in the mud tank. Preferably, the collection zone is in a central depressed part of the mud tank to allow gravity to assist in moving debris towards the collection zone. Preferably, a pair of collection sweeps are used on opposed sides of the collection zone. The collection sweeps are preferably pivotally mounted to follow an arcuate path along the surface of a cylindrical confining wall of the mud tank. Sweep drive mechanisms operate the sweeps. The collection sweeps are preferably used in conjunction with a disposal sweep that sweeps debris collected in the collection zone by the collection sweeps out of the collection zone and through the opening in the mud tank, from where it may be readily disposed of. The mud tank is typically operated in conjunction with a hydrovac vehicle.

    Abstract: Molten slag is granulated with water to produce a granulated-slag/water sry that is fed into the bottom of a horizontally extending foraminous drum. This drum has radially inwardly extending vanes and is rotated to lift up the granulated slag and separate it from the water, discharging the slag onto a conveyor belt for storage or further use. The water running out of the slag slurry is recirculated for use in the initial granulation step for the molten slag stream.
