A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings created during the well drilling process. An apron assembly collects drill cuttings and deposits such cuttings on a central rotor having multiple distinct chambers. A first chamber is loaded with drill cuttings. The central rotor thereafter cycles to a second position wherein a pressure seal is formed around the loaded first chamber. An air knife or similar device is used to blast compressed gas at the cuttings in the sealed chamber and force the cuttings against a screen. Solid components of the cuttings remain in the sealed chamber, while liquid components pass through the screen and are collected using an auger assembly. Following such separation, the rotor is cycled again, allowing dried cuttings to empty from the first chamber. The process is repeated for each chamber of the rotor.

Method and apparatus for separating and removing fluids from drill cuttings

A method and apparatus is provided for removing fluids, particularly entrained and/or adherent fluids, from drill cuttings generated during the well drilling process. A generally cylindrical wire-wrapped screen having a bore therethrough rotates about its longitudinal axis. Suction pressure is applied through the inner bore of the cylindrical wire-wrapped screen. As fluid-laden drill cuttings are deposited on the outer surface of the cylindrical wire-wrapped screen, fluids are drawn off of the cuttings and evacuated from the inner bore of the cylindrical wire-wrapped screen. Solid components of the cuttings remain on the outer surface of the cylindrical wire-wrapped screen and eventually roll off the screen. A scraper member is provided to agitate cuttings deposited on the outer surface of the cylindrical wire-wrapped screen.
