METHOD OF AND DEVICE FOR LIFTING HYDRAULIC MIXTURE FROM DEEP DEPTHS Russian patent published in 2007 - IPC F04D7/04 F04D13/08 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in development of underwater mineral deposits. Proposed method comes to transportation of solid particles in hydraulic mixture and delivery of hydraulic mixture into suction pipeline of pump value of concentration of hydraulic mixture flow in suction pipeline is set preliminarily before brining solid particles out of hydraulic mixture flow in ocean at depth corresponding to parameters of lifting and composition of hydraulic mixture is set preliminarily. Solid particles are continuously let out from hydraulic mixture flow getting into pump, and value of concentration of hydraulic mixture formed by flow of delivery pipeline with solid particles getting into flow is checked. Value under checking is compared with preset value and they are brought into agreement regulating delivery of pump. Device for lifting hydraulic mixture contains pump and accumulator installed in column of pump delivery pipeline. Pump and accumulator are submerged in ocean. Accumulator is installed in intermediate cross section of suction pipeline. Working wheel is installed in accumulator being provided with blades, and delivery pipeline has end piece arranged in accumulator.

EFFECT: improved lifting of hydraulic mixtures form depth owing to control of value of concentration of hydraulic mixture and provision of continuous lifting of materials without grinding of their solid particles.
