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.
Claims20
A system comprising:
- a frame with a perimeter structure defining a periphery of the frame wherein the perimeter structure has an inner wall and a lip extending from the inner wall and further wherein the frame has a plurality of regions defined by support members within the perimeter structure;
- and
- a plurality of segments respectively inserted into the plurality of regions wherein each segment of the plurality of segments has a flange interfacing with the lip of the perimeter structure and the support members to secure the segment in the region.
A method comprising:
- arranging a plurality of screen modules having a first plurality of cells within regions of a frame wherein the regions are defined by a perimeter wherein the plurality of screen modules have cells covered by a first mesh;
- removing the screen module from the frame to create a vacant region in the frame;
- and
- inserting another screen module into the vacant region of the frame.
1 more element
A method comprising:
- placing support members on a frame with a perimeter structure to define a region;
- inserting a screen segment with a flange into the region;
- interlocking the flange of the screen segment with the perimeter structure.
