Abstract
A screen assembly for vibratory separation includes a screen having a plurality of raised screen components formed therein, with each of the raised screen components defining a face oriented to oppose a flow direction of the screen assembly. In examples, a screen of the screen assembly is assembled from a plurality of metal cloth layers bonded together. Bonding of the metal cloth layers may be accomplished by a sintering process.
Claims22
A screen assembly for vibratory separation, comprising:
- a screen comprising a plurality of wire cloth layers, the screen defining a width and a length, each of the wire cloth layers having a plurality of raised screen components, the plurality of raised screen components being spaced apart from one another along both the width and the length, the plurality of wire cloth layers being sintered together, the plurality of raised screen components being arranged in a staggered configuration to define a serpentine flow of fluids and solids over the screen and through the raised screen components, the plurality of raised screen components each defining a rear face oriented to oppose a flow direction of the screen assembly, the plurality of raised screen components each defining a top face sloping downward from the rear face to a bottom surface plane of the screen and being oriented to oppose a vibratory direction of the screen to a greater extent than the bottom surface plane, an interface of the rear face and the top face being curved, the plurality of wire cloth layers being formed from a mesh material, the rear face directing the serpentine flow of fluids around a curve defined by the interface.

A screen for vibratory separation, comprising:
- a plurality of wire cloth layers, each of the plurality of wire cloth layers defining a width and a length, each of the wire cloth layers having a plurality of three-dimensional (3D) raised screen components formed therein, the plurality of three-dimensional (3D) components being spaced apart from one another along both the width and the length and being arranged in a staggered configuration to define a serpentine flow of fluid and solids over the screen and through the raised screen components, each of the three-dimensional (3D) components defining a top face and a rear face, the top face being generally planar and angled with respect to a bottom surface plane of the screen, the rear face and an interface of the rear face and the top face being curved, the rear face facilitating the serpentine flow of fluid and solids over the screen,
- wherein the plurality of wire cloth layers are diffusion bonded and sintered together to form the screen.

A method of assembling a screen for vibratory separation, comprising:
- forming a plurality of raised screen components in a plurality of wire cloth layers, each of the plurality of raised screen components defining a top face and a rear face, the top face defining a generally planar surface that is angled with respect to a surface of the screen, the rear face and the top face being joined at an interface that is curved, the plurality of raised screen components being arranged in a staggered configuration and an arrangement in which the plurality of raised screen components are spaced apart from one another along both a width and a length of the screen to define a serpentine path through which fluids and solids are flowable over the screen and through the raised screen components, the rear face facilitating flowing the fluids and solids along the serpentine path;
- arranging the plurality of wire cloth layers in a stack;
- and
- bonding the stack of wire cloth layers to form the screen, wherein the bonding of the stack of wire cloth layers includes sintering the stack of wire cloth layers together.
