ABSTRACT:
An apparatus for cleansing a stream of drilling fluid fouled drill cuttings having a housing divided into a plurality of compartments each designed to retain cleansing fluid. A spinning force is imparted into the incoming fouled drill cuttings in an inlet chamber wherein cleansing fluid is intimately mixed with the fouled drill cuttings. A decanting chamber removes liberated drilling fluid from the cuttings and disposes of such drilling fluid from the apparatus via a drain trough assembly. The underflow from the decanter is passed through a solids concentrating assembly wherein the coarse solids are deposited in a concentrating assembly bottoms chamber wherein the settled drill cuttings are removed from the apparatus. The overhead stream from the solids concentrating assembly is directed to a second decanter for removal of any remaining drilling fluid and fine drill cuttings entrained therein from the apparatus via the drain trough assembly. The remaining fluid in the concentrating assembly bottoms chamber is recirculated to the second decanting chamber and the inlet chamber.
