CYLINDER-SHAPED RESERVOIR FOR OIL PRODUCTS STORAGE Russian patent published in 2009 - IPC B65D88/34 E04H7/02 

FIELD: mechanics.

SUBSTANCE: reservoir is mounted on a foundation and consists of a tapered bottom, a body wall, a floating roof with a rim seal, a receptor-and-dispenser unit, a drainage unit and a device for bottom sedimentation washaway. The receptor-and-dispenser unit is mounted inside the foundation in immediate proximity to the bottom taper base; the drainage unit and the device for bottom sedimentation washaway are mounted below the bottom taper vertex; the floating roof design provides for maintenance of technological clearances between the roof and the reservoir top edge and between the roof and the bottom taper vertex when the roof is in the uppermost and lowermost positions accordingly.

EFFECT: improved reservoir effective-volume utilisation factor.
