  • Patent number: 11872571
    Abstract: A batch centrifuge having a filter screen that can be expeditiously removed and replaced and that is more rigid and more durable than filter screens that are typically employed in current practice. The batch centrifuge may include a centrifuge basket and a cylindrical filter screen disposed within the centrifuge basket, wherein the filter screen is formed of a plurality of curved panels that fit together at adjoining edges. In some embodiments, each of the curved panels may be small enough to fit through an opening in the top of the centrifuge basket without being bent or otherwise deformed.

  • Publication number: 20230105431
    Abstract: A support grid assembly for use in a pressure vessel includes one or more screen panel assemblies that are flexibly, fluidly coupled to a central fluid manifold. Each screen panel assembly is operably slidably inserted into a central fluid manifold, whereby a flexible connection fluidly individually seals each screen panel assembly to the central fluid manifold. Through the use of a flexible connection, each screen panel assembly can individually slide, rotate or otherwise shift relative to the central fluid manifold and into engagement with a vessel floor regardless of inconsistencies in the vessel floor.
