DEVICE FOR REMOVING SURFACE LAYER OF OIL-CONTAINING LIQUIDS Russian patent published in 2017 - IPC E02B15/04 C02F1/40 

FIELD: chemistry.

SUBSTANCE: device for removing the surface layer of oil-containing liquids contains a floating oil collecting device in the form of a sector belt conveyor consisting of an endless belt of oil-resistant material, perforated on the sides, mounted on three hollow sealed drums, one of which is made as leading, and the other - as slaves equipped with one sprocket at the ends for driving the belt perforated on the sides, and fixed with the belt by means of pivots on the movable frame. Between the hollow drums and the belt branches, a float is located in the form of a hollow or foam-filled container of rectangular cross-section and in the form of a sector in the longitudinal section attached to the movable frame and configured to swing along with the belt conveyor of the relative surface layer of oil-containing liquids around the axis of the leading drum mounted on two supports to the fixed frame together with the drive. The device also has a drainage system made in the form of two drain trays that act as scrapers mounted on a movable frame with the possibility of contacting them with the endless belt at the location of the fixed frame. The belt perforated on the sides is made in the form of corrugated surfaces inside and outside, for example, in the form of a sinusoid in its cross-section to increase the contact area between the conveyor belt and the surface layer of oil-containing fluids. The hollow drums are smooth, and the scrapers have a profile copying the profile of the belt perforated on the sides.

EFFECT: productivity of removing oil products from the surfaces of reservoirs is increased.
