Abstract
A substantially planar screen for a solid particle separator is formed from one or more layers of mesh. The one or more layers of mesh are formed into a series of ridges separated by channels within the plane of the screen. The wire mesh is bonded to a rigid or semi-rigid panel having a plurality of relatively large openings as compared to those of the mesh to create a plurality of repairable screen cells. The support panel is formed with or bent into a series of alternating ridges and channels to create the ridges and channels in the wire mesh when it is bonded to the panel. The cross-sectional shape of the ridges are generally triangular to maximize exposure of surface area of the screen to a flow of material to be separated. Flat surfaces on the ridges and in the channels facilitate repair of screen cells with solid plugs.
Claims22
A screen for a shaker comprising:
- a support panel formed with a series of alternating parallel ridges and channels and a plurality of openings formed therein;
- and a first web being bonded to a surface of the panel to form a complementary series of alternating ridges and channels of wire mesh, the first web overlaying the plurality of openings and bonded to the panel around each of the openings to form a plurality of cells of wire mesh independently supported within the screen.
A screen for a separator comprising:
- a first web of wire mesh;
- a second web of wire mesh immediately adjacent to the first web of wire mesh, the first and second webs of wire mesh cooperating to prevent particles having a dimension greater than selected size from passing through the screen;
- a support panel formed with a first series of alternating parallel ridges and channels and a plurality of openings;
- the first web and the second webs being bonded to a surface of the panel around each one of the plurality of openings to create in the first and second webs a second series of alternating ridges and channels complementary with the first series and a plurality of independently supported cells of wire mesh overlaying each of the plurality of openings.
A screen for a shaker comprising:
- a first web of wire mesh;
- a second web of wire mesh immediately adjacent to the first web of wire mesh, the first and second webs of wire mesh cooperating to prevent particles having a dimension greater than selected size from passing through the screen;
- and
- a relatively rigid support panel including a series of alternating parallel ridges and channels lying in substantially a horizontal plane when attached to a shaker and to which is bonded the first web and the second web to create a complementary series of alternating ridges and channels of wire mesh;
- wherein,
- the panel includes a plurality of openings, the first and second webs of wire mesh being bonded to the panel around each one of the plurality of openings to form a plurality of screen cells within the screen, each screen cell being thereby independently supported by the panel;
- each of the ridges in the panel including two flat sides forming a substantially triangular shape, each of the two flat sides having defined therein at least one of the plurality of openings;
- and
- each of the channels includes a substantially flat, horizontal bottom surface between two ridges and the bottom surface includes at least one of the plurality of openings is formed therein.
