  • Patent number: 11612836
    Abstract: A feedwell comprising a plurality of holes disposed in a bottom thereof, at least some of the holes having a tube disposed thereabout which extends downward or otherwise away from an interior of the feedwell. Optionally, a large center hole can be provided and it can have a tube disposed around it. By providing a plurality of holes spread across a large portion of the bottom of the feedwell, lower velocity flow rates from the feedwell to a sedimentation chamber can be provided, thus reducing induced turbulence in the fluid within the sedimentation chamber, while still providing sufficient separation of the feedwell from the sedimentation chamber so that the contents of the feedwell can be properly and adequately mixed.

  • Publication number: 20180133622
    Abstract: Dilution check valves, pumps, systems, and methods of use, useful for dilution of incoming feed into a feedwell or feed system that can be easily installed and removed on solid/liquid separation units. The feed dilution apparatuses or systems can be installed in a single location or in multiple locations around a feedwell, transferring supernatant drawn from single or multiple locations within a solid/liquid separation tank. Optionally, an in-line turbine style pump and/or downward draft configuration can be used to provide efficient pumping and accurate adjustment of volume by increasing or decreasing rotation speed. The feed dilution pumps can optionally be installed using a quick fit system that allows removal and replacement during operation without the need for mobile cranes or heavy lifting equipment.
