DEVICE FOR REMOVAL OF OIL-BEARING FLUID SURFACE LAYER Russian patent published in 2014 - IPC C02F1/40 

FIELD: process engineering.

SUBSTANCE: invention relates to removal of oil-bearing fluids and can be used in whatever industry. Proposed device comprises oil collection means composed of endless belt conveyor made up of thin belt with perforated sides made from oil-resistant material fitted at two hollow sealed drums, one drive and two driven drives. Said drums have one sprocket at their ends to drive said belt and are secured together with said belt to fixed frame. Float composed of hollow vessel is arranged between hollow drums and belt runs. Besides, proposed device comprises drain system composed by drain scraper mounted at moving frame to get in contact with endless belt above settling tank or aboard self-propelled ship fore. Triangular skids are secured to surfaces of drums and float and there between. Note here that said conveyor can swing relative to fluid surface layer around drive hollow sealed drum mounted at two supports of fixed frame mounted at ship fore or at settling tank in sop. Float and skids are mounted between drums and belt flights while scraper is an inclined tube with grooves made at its bottom section their width being equal to depth of perforated belts and height of stuck oil products while width at top section approximates to thickness of every belt. Note here that pockets are made at scraper of tube bottom section. Groove top part features width approximating to belt thickness. Oil product drain tube is connected with accumulation tank by flexible hose while scraper is arranged at the belt right or left side depending upon rotating sense of conveyor belt.

EFFECT: higher efficiency of oil products removal.
