  • Patent number: 6484885
    Abstract: A new and unique design use of directional and re-directional raised ribs on a solids control filtering screen, such as those used in drilling wells for hydrocarbons and other substances, in conjunction with a coordinated system of hanging such screens and directing and redirecting the flow of trapped solids over the surface of such screens, is disclosed for use with a vibratory shaker. The invention counteracts the natural tendency of trapped solids to migrate to and congregate in the lowest areas of a suspended screen and facilitates a dryer fluids discharge, as well as more effectively utilizing the available screening surface area, and therefore the invention reduces the incidence of screen wear and tearing and increases the flow rate conductants and drying capabilities through the screen.
