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.
Claims17
A mechanical separation device comprising:
- a housing with an elongate length having a feed inlet at a first end section and a discharge outlet at a second end section;
- a conveyor assembly positioned adjacent the housing and moveable relative thereto, the conveyor assembly having a shaft, a plurality of paddles and a plurality of flingers, wherein the plurality of paddles are mounted to and extend radially from the shaft and the plurality of flingers are mounted to one or more of the plurality of paddles adjacent to an outer radial end thereof, and wherein the plurality of flingers are oriented to extend outward laterally at an angle relative to the radially extending one or more of plurality of paddles;
- and
- a screen positioned adjacent the plurality of flingers and the outer radial end of the one or more of plurality of paddles, wherein the plurality of flingers and the outer radial end of the one or more of plurality of paddles are spaced from the screen by a gap.

A mechanical separation device comprising:
- a housing with an elongate length having a feed inlet at a first end section and a discharge outlet at a second end section;
- and
- a conveyor assembly positioned adjacent and moveable relative to the housing, the conveyor assembly having a shaft, two or more paddles and a plurality of flingers, wherein the two or more paddles extend radially outward from the shaft and the plurality of flingers are mounted to the two or more paddles adjacent to an outer radial end of each of the two or more paddles, and wherein the plurality of flingers are oriented in a helical fashion along an axial length of the two or more paddles, wherein the plurality of flingers are oriented to extend outward laterally at an angle relative to the two or more paddles:
- and
- a screen positioned adjacent the plurality of flingers and the outer radial end of each of the two or more paddles, wherein the plurality of flingers and the outer radial end of each of the two or more paddles are spaced from the screen by a gap.
