Abstract
Systems and methods for separating fluids from drill cuttings. Specifically, the invention relates to shakers that incorporate a vacuum system and methods of operating such systems to effect a high degree of fluid separation. The system and methods are effective across a variety of screen sizes, vacuum flows and vacuum designs.
Claims17
A method of retro-fitting a shaker to include an air vacuum system, the air vacuum system for improving the separation of drilling fluid and drill cuttings on the shaker, the method comprising the steps of:
- a. installing a vacuum frame and manifold over screen support rails of a shaker;
- b. installing a screen on the vacuum frame and manifold such that the vacuum frame and manifold mates with the underside of the screen;
- and
- c. securing each of the support rails, vacuum screen and manifold and screen together for enabling a vacuum pressure to be applied to the underside of the screen;
- wherein the shaker has at least two pairs of support rails and the vacuum frame and manifold is installed on a downstream pair of support rails, leaving at least one upstream pair of support rails without a vacuum frame and manifold.
