APPARATUS FOR SEPARATING SOLIDS, LIQUIDS AND GASES WITH INTEGRAL DRIVE MOTOR HAVING A HOLLOW MOTOR SHAFT DEFINING AN IMPELLER DRUM

摘要

An apparatus for separating a fluid having a lighter specific gravity from a fluid having a heavier specific gravity and for separating fluids having lighter specific gravity from fluids having a heavier specific gravity includes an electric motor including an annular stator and a rotor having a rotor shaft having a hollow interior defining a rotatable drum having a drum rotational axis, the rotor passing through the stator and rotatably mounted on shaft mounting structure; a fluid passage structure for receiving fluids and solids of a mixture stream to be separated having a longitudinal axis, the fluid passage structure including a the rotatable drum and an impeller contained within the rotatable drum for separating with centrifugal force the constituents of the stream into radially arrayed layers of progressively increasing specific gravity.
