Abstract
A disc for use in a disc screen is disclosed. The auger disc includes a central longitudinal disc axis and a hub extending a length along the longitudinal disc axis. The longitudinal disc axis is coaxial with the center of the hub. The hub further includes a hub surface and a helical ridge structure extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees. The auger disc has a disc rotation axis that is parallel to the central longitudinal axis and is offset from the center of the hub. The auger disc is constructed to rotate about the disc rotation axis.
Claims25
An auger disc (10, 110) for use in a disc screen (40) comprising:
- a central longitudinal disc axis (15, 115);
- a hub (22, 122) extending a length along the longitudinal disc axis, the longitudinal disc axis is coaxial with the center of the hub, the hub further comprising:
- a hub surface (23, 123);
- a helical ridge structure (25, 125) extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees (35);
- and
- a disc rotation axis (20, 120) that is parallel to the central longitudinal axis and offset (30, 130) from the center of the hub;
- wherein the disc is constructed to rotate about the disc rotation axis.
A disc screen (40) comprising;
- a first and second adjacent auger discs, each disc comprising:
- a central longitudinal disc axis (15, 115);
- a hub (22, 122) extending a length along the longitudinal disc axis, the longitudinal disc axis is coaxial with the center of the hub, the hub further comprising:
- a hub surface (23, 123);
- a helical ridge structure (25, 125) extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees (35);
- and
- a disc rotation axis (20, 120) that is parallel to the central longitudinal axis and offset (30, 130) from the center of the hub;
- wherein the disc is constructed to rotate about the disc rotation axis.
- wherein the helical ridge structure from the first disc is interleaved with the helical ridge structure of the second disc (52).
An auger disc for use in a disc screen comprising:
- a central longitudinal disc axis (15, 115);
- an inner shaft (150) that runs along the central longitudinal axis;
- an outer auger shaft (145) constructed to slide over a portion of the inner shaft, the outer shaft comprising a hub, wherein the hub comprises a hub surface (23, 123) and a helical ridge structure (25, 125) extending away from the hub surface and twisting about the longitudinal axis at least 360 degrees (35);
- and
- a self-aligning spline (155) forming a detachable connection between the inner shaft and the outer shaft.
