Abstract
A method and/or a system filters particles using a screen with modular segments installed into a frame. The frame has a perimeter structure and an orthogonal array of support members. The segments have a segment perimeter frame, an orthogonal array of ribs and a mesh stretched across the segment. When the mesh of the segments is damaged, the damaged segment is removed from the frame and a replacement segment is installed.
Claims17
A screen, comprising:
- a frame, including:
- a perimeter structure comprising a top perimeter surface, a bottom perimeter surface, and an inner perimeter wall, wherein the bottom perimeter surface is a bottom extremity of the perimeter structure;
- a lip formed in the inner perimeter wall between the inner perimeter wall and the bottom perimeter surface;
- and
- a support member connected to the perimeter structure, wherein the support member comprises a top support surface, a bottom support surface, a first support side, and a second support side, and wherein the first support side and the second support side oppose one another and are flat from the top support surface to the bottom support surface, wherein the bottom perimeter surface extends lower than the bottom support surface, and wherein the inner perimeter wall and one or more of the first support side or the second support side form an opening;
- and
- a segment positioned in the opening and removably connected to the frame, the segment including:
- a segment perimeter frame having a top segment surface, a bottom segment surface, an outer segment wall, and an inner segment wall, wherein the outer segment wall contacts the inner perimeter wall and the inner segment wall contacts the first support side or the second support side;
- a first flange extending from the outer segment wall at the bottom segment surface and a second flange extending from the inner segment wall at the bottom segment surface, the bottom segment surface being a lowest extremity of the segment perimeter frame, wherein the first flange extends at least partially into the lip formed in the inner perimeter wall and the second flange extends beneath the bottom support surface, to removably connect the segment to the frame;
- and
- a rib connected to the segment perimeter frame, wherein the segment perimeter frame and the rib define a plurality of cells of the segment;
- wherein the first flange and the second flange define the bottom segment surface, wherein the bottom segment surface extends below the bottom support surface, and wherein the bottom segment surface does not extend below the bottom perimeter surface.
