  • Patent number: 11351483
    Abstract: A dewatering unit in the form of a railcar having bogies thereon to move the unit on rail tracks. The dewatering unit has first and second ends, first and second sides, and a bottom that bound and define an interior chamber. A conveyor is provided in the interior chamber and screens are located in the bottom and first and second sides. A grizzly is located below an opening in the unit's top and above the conveyor. Stabilizing assemblies are deployed to contact the ground and lift some weight off of the bogies prior to loading. A solid material/liquid mixture is dropped through the opening and onto the grizzly which partially fractures the solid material. Further fracturing is undertaken by conveyor drag bars and crushers located adjacent the conveyor. Liquid drains from the unit through the screens. The dewatered solid material is lifted out of the unit by the conveyor.

  • Patent number: 11123768
    Abstract: A system and method of transporting and unloading a load from a floating container that includes placing a load on a floating container at a first location, wherein the load is a mixture of solid material and liquid; moving the floating container with the load on a body of water from the first location to a remote second location; positioning the floating container so that a crane at the second location is within reach of the load; positioning a dewatering unit at the second location proximate the crane; unloading a quantity of the mixture of solid material and liquid from the floating container with the crane; depositing the quantity of the mixture of solid material and liquid into the dewatering unit; and dewatering the quantity of the mixture of solid material and liquid with the dewatering unit.

  • Patent number: 8147689
    Abstract: A dewatering conveyor system for dewatering chunks of petroleum coke or the like material which is mixed with large volumes of water, wherein the conveyor employs lateral drag bars, the top flight of which conveyor slides forwardly on a screening deck having dewatering screens, and the bottom flight of which conveyor slides rearwardly on a sluice deck underlying the screening deck, wherein a major portion of the conveyor rearward of its discharge end is contained by tail end wall means and side and bottom wall means which can contain large volumes of coke and water, wherein, for handling large volumes of water the discharge end of the conveyor is elevated, e.g., up to 20 ft. or more above the tail end of the conveyor such that water dropping thru the screens will run down toward the tail end of the conveyor and leave the discharge end above the water line, and wherein a drain port is located thru the bottom wall means at a tail end portion thereof.
