Abstract: An apparatus, a system and a method for reinforcing a screen has a screen rod assembly extending from a first end to a second end. The screen rod assembly encloses an interior. A spring-loaded plunger is located in the interior and adjusts the length of the screen rod assembly. A ball joint is on the screen rod and defines sections of the screen rod assembly that bend around the ball joint to reduce the length of the screen rod. A sleeve extends from a screen with segments separated by a fold line extending along a width of the screen. The sleeve receives the screen rod assembly to reinforce the screen. In an embodiment, a screen pinch assembly is defined where the sleeve engages a retention clasp of a screen tensioning system that receives the screen. The screen pinch assembly holds the screen in place.

Abstract: A separator having a pressure differential generating system is disclosed. The pressure differential generating system generates a pressure differential with respect to a screen of the separator. Fluid is supplied to the pressure differential generating device to generate the pressure differential across a screen of the separator. The separator can be utilized to separate drill cuttings from drilling fluid to increase an amount of drilling fluid recovered as a result of the pressure differential.
