Abstract
Screen designs and screens for a mechanical separation device are disclosed for separating solids from liquids in a process stream. A screen may have a plurality of openings, which are conical shaped, having a diameter of about 1.0 mm to about 1.4 mm in size that are formed on a stainless steel sheet.
Claims19
A mechanical separation device comprising:
- a housing with a teed inlet at a first end section of the housing and a discharge outlet at a second end section of the housing, the feed inlet configured to receive a slurry comprising solids within a liquid medium;
- a screen comprising:
- a plurality of openings formed on a sheet of metal material, wherein each opening of the plurality of openings comprises a uniform diameter of about 0.8 mm to about 1.5 mm in size;
- wherein the plurality of openings comprise a geometric shape of a circle for each opening on the sheet of metal material;
- wherein the screen is configured to separate at least a portion of the liquid medium from the solids;
- and
- a bar handle to lift the screen on and off the mechanical separation device;
- and
- a conveyor assembly within the housing, the conveyor assembly having a shaft, a plurality of paddles and a plurality of flingers, wherein the plurality of paddles extend radially from the shaft and the plurality of flingers are mounted to one or more of the plurality of paddles at an outer radial end portion thereof, and wherein the plurality of flingers are configured to move the solids and the liquid medium along an axial length of the housing toward the discharge outlet.
