ABSTRACT:
A pair of substantially common elevation tank compartments are provided including lower sump portions and a first tank compartment includes an inlet pipe portion for admitting drilling cuttings in a downward direction into the first tank compartment. The inlet pipe portion includes at least one lateral cleaning fluid jet and the first tank compartment includes additional horizontal cleaning fluid jets for directing jets of cleaning fluid through the drilling cuttings as they are admitted into the first tank compartment and subsequently directing jets of cleaning fluid through the cleaning fluid and drilling cuttings within the first tank compartment below the liquid level therein. The upper portion of the second tank compartment includes a vibratory screen-type separator positioned thereover and structure is provided for pumping fluent material from the sump of the first tank compartment to the separator whereby the larger size, cleaned cuttings will be separated from the other fluent material which passes downwardly through the separator and into the cleaning fluid within the second tank compartment. Pump structure is provided for pumping fluent cleaning material from the sump of the second tank compartment to the various aforementioned cleaning fluid jets and a liquid level balance pipe is connected between upper portions of the tank compartments at levels spaced slightly below the liquid levels therein.
