A centrifuged oil residue separation and purification integration machine is characterized in that a dephosphorization circulating pump pumps external crude oil into a dephosphorization barrel through an oil conveying pipeline, water steam generated by using a steam production system is conveyed to the crude oil through a high pressure gas tube, and the water steam is mutually blended with oil residues in the dephosphorization barrel to make the specific gravity of the oil residues be larger than that of oil in order to realize a dephosphorization effect; an oil material in the dephosphorization barrel is sent into the inner cavity of a rotating drum through a second high pressure oil tube by an oil pump after dephosphorization is completed, the rotating drum and a screw propulsion shaft run at a high speed under the driving of a main motor, a solid phase with large mass tightly cling to the inner wall of the rotating drum, and relative movement of the rotating drum and the screw propulsion shaft makes a blade on the screw propulsion shaft discharge the solid phase clinging to the inner wall of the rotating drum to a residue discharge chamber; and clear oil obtained after separation flows to the large end of the rotating drum, and flows to an oil chamber from an oil outlet on a hollow shaft in order to realize oil-residue separation of the crude oil. The purpose of the invention is to provide the centrifuged oil residue separation and purification integration machine with the advantages of good dephosphorization effect, compact structure, good working continuity, high working efficiency, small manual labor intensity and good oil product quality.
