Abstract: A mechanical separation device optionally includes one or more of a housing, a screen a rotary assembly, one or more wash bars and a plurality of nozzles. The screen can be positioned within the housing to separate at least a portion of the liquid medium from the solids. The rotary assembly can be within the housing and can be configured to move the solids and the liquid medium along an axial length of the housing toward the discharge outlet. The one or more wash bars can be within the housing and can be positioned adjacent the screen. The plurality of nozzles can be spaced along the one or more wash bars. The one or more wash bars can be configured to receive a wash fluid and the plurality of nozzles configured to discharge the wash fluid against the screen.

Abstract: A rotary tool for a mechanical separator, the tool can optionally comprise: a center shaft having a longitudinal axis; a plurality of longitudinal paddles coupled to the shaft, at least one paddle of the plurality of paddles having an inner edge and aligned radially relative to the longitudinal axis, wherein the at least one paddle has an elongate extent along the longitudinal axis with opposing lateral sides along the elongate extent; and a flange having a triangular shape in a radial cross-section, the flange affixed to the inner edge of the at least one paddle and having an apex radially inward of the at least one paddle. Other examples of the application include the rotary tool having a plurality of tools and the mechanical separator having the capability of being raised or lowered to alter a residence time of slurry within the mechanical separator.
