20120152860 | 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 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. | 06-21-2012 |
