METHOD FOR LIFTING MULTI-COMPONENT MIXTURE FROM HIGH DEPTHS AND SYSTEM FOR REALIZATION OF THE METHOD Russian patent published in 2007 - IPC F04F1/20 

FIELD: mechanical engineering, possible use for extracting mineral resources.

SUBSTANCE: method includes transporting water in composition of water-air mixture, creating multi-component mixture after influx of hard particles into stream of air-water mixture of forcing pipeline of pump and transportation of stream of multi-component mixture into forcing pipeline. Further the method includes removing multi-component air mixture from composition of stream with later creation hydro-mixture stream in forcing pipeline. In advance, the value of concentration is set for separate stream of hydro-mixture for removal of hard particles from its composition in the ocean at depth, corresponding to lifting parameters and composition of hydro-mixture. Hard particles, injected into stream of water-air mixture of forcing pipeline, are continuously removed from composition of separate stream. The air removed from composition of multi-component stream is repeatedly injected into water stream of forcing pipeline, concentration value of hydro-mixture stream of forcing pipeline is monitored. The value being monitored is compared to given value and match is achieved between the two by adjusting pressure value of air-water mixture, in the stream of which influx of hard particles occurs.

EFFECT: possible continuous lifting of mineral resources in composition of multi-component mixture, including sintering thereof and transportation of hard particles through the pump.
