DEVICE FOR SEPARATING TWO LIQUIDS OF DIFFERENT DENSITIES IN A TANK CONTAINING THESE TWO LIQUIDS

摘要

A device for separating two liquids of different densities in a tank containing these two liquids one above the other which includes a separating element floating with clearance along the vertical wall of the tank between the two liquids, and a flexible sealing skirt of reduced thickness adapted to tangentially contact the vertical wall of the tank and to turn upwardly or downwardly along the tank wall without mixing of the two liquids when the tank is switched from a filling to an emptying operation or vice versa. The separating element may be provided with openings for passages of pipes, the edges of which are also provided with flexible sealing skirts, for filling or emptying the tank. Also, the separating element may include grooves for draining decanting products from the upper liquid toward the lower liquid.
