DIRECT DRIVE VERTICAL CUTTINGS DRYER AND METHODS OF MAKING AND USING, AND RETROFITTING CUTTINGS DRYERS
A drill cuttings dryer that includes a centrifuge especially adapted to process drill cuttings; a torque converter in communication with the centrifuge; a motor; and, a drive shaft in communication with both and linking the motor and torque converter. A method of processing drill cuttings containing a liquid by introducing the drill cuttings to centrifuge, and then providing power from a motor to power the centrifuge and subject the drill cuttings to centrifugal force sufficient to remove at least some of the liquid from the drill cuttings, wherein the motor provides power to the centrifuge through a drive shaft. A method of retrofitting a drill cuttings dryer that utilizes a belt and sheave system, includes replacing the belt and sheave system with a drive shaft based system.
1 . A drill cuttings dryer comprising:
a centrifuge adapted to process drill cuttings;
a torque converter with a torque converter first end in communication with the centrifuge and having a torque converter second end;
a motor; and,
a drive shaft having a drive shaft first end in communication with the motor and having a drive shaft second end in communication with the torque converter second end.
2 . The dryer of claim 1 , wherein the converter is a 90 degree torque converter.
3 . A method of processing drill cuttings containing a liquid:
introducing the drill cuttings to a centrifuge;
providing power from a motor to power the centrifuge and subject the drill cuttings to centrifugal force sufficient to remove at least some of the liquid from the drill cuttings, wherein the motor provides power to the centrifuge through a drive shaft.
4 . A method of retrofitting a drill cuttings dryer, wherein the dryer comprises a centrifuge adapted to process drill cuttings; a motor; and a power translation system between the motor and the centrifuge comprises a belt and sheave system, the method comprises:
replacing the belt and sheave system with a drive shaft so that the translation system comprises the drive shaft.
