Abstract
A screen assembly for a vibratory separator has been invented, which, in certain aspects, has at least two ridge-valley series of screening material with a plurality of alternating ridges and valleys of screening material, and at least one flat area of screening material adjacent at least one of the ridge-valley series.
Claims26
A screen assembly for a vibratory separator, the screen assembly comprising
- at least two ridge-valley series of screening material comprised of a plurality of alternating ridges and valleys of screening material,
- at least one flat area of screening material adjacent at least one of the ridge-valley series,
- wherein the at least one flat area of screening material is a flat area at a leading end of the screen assembly, and
- wherein the at least one flat area of screening material is at least three flat areas of screening material adjacent each ridge-valley series.
A screen assembly for a vibratory separator, the screen assembly comprising
- at least two ridge-valley series of screening material comprised of a plurality of alternating ridges and valleys of screening material,
- at least one flat area of screening material adjacent at least one of the ridge-valley series,
- screening material is at a trailing end of the screen assembly, and
- wherein the at least one flat area of screening material is at least three flat areas of screening material adjacent each ridge-valley series.
A screen assembly for a vibratory separator, the vibratory separator apparatus including vibrating apparatus for imparting vibratory force to the screen assembly, the screen assembly having a top and a bottom and comprising
- at least two ridge-valley series of screening material comprised of a plurality of alternating ridges and valleys of screening material, each valley having a lower most portion,
- at least one flat area of screening material adjacent at least one of the ridge-valley series, the at least one flat area of screening material having a flat top surface,
- the lower most portions of each valley in a first flat plane and the flat top surface of the at least one flat area of screening material in a second flat plane, said first flat plane parallel to said second flat plane, fluid flowable from the top of the screening assembly, down through the screening material, and out from the bottom of the screening assembly, and
- said screen assembly able to withstand the vibratory force imparted by the vibrating apparatus.
A method for treating fluid with a vibratory separator, the fluid having material entrained therein to be separated therefrom, the method comprising,
- introducing the fluid onto a screen assembly in the vibratory separator, the screen assembly comprising at least two ridge-valley series of screening material comprised of a plurality of alternating ridges and valleys of screening material, and at least one flat area of screening material adjacent at least one of the ridge-valley series,
- the lower most portions of each valley in a first flat plane and the flat top surface of the at least one flat area of screening material in a second flat plane, said first flat plane parallel to said second flat plane, fluid flowable from the top of the screening assembly, down through the screening material, and out from the bottom of the screening assembly, and
- said screen assembly able to withstand the vibratory force imparted by the vibrating apparatus, and
- separating material from the fluid with the screen assembly.
