SCOOP-SCRAPER SCREW CONVEYOR Russian patent published in 2018 - IPC C08J11/00 

FIELD: machine building; oil and gas industry.

SUBSTANCE: invention relates to structural elements of devices for processing and utilization of oil sludge and soil contaminated with oil or oil products. Scoop-scraper screw conveyor comprises a main tube fixed to a shaft, which is adapted to be connected to a shaft rotation device. There are at least two support rings on this pipe, fixing the position of the main pipe in the casing of the conveyor. On said support rings are fixed with a clearance relative to the casing of the conveyor of the blade, between these support rings is mounted on the main pipe, with the possibility of removing the scraper adhering to the inner surface of the casing.
