COMPLEX TO PRODUCE MINERALS FROM SHELF AREA OF WORLD OCEAN Russian patent published in 2012 - IPC E21C50/00 

FIELD: mining.

SUBSTANCE: complex comprises a basic vessel, which is kinematically connected to a production tool, comprising a rolling capture device installed on skis, a transportation device, which connects a production tool with basic vessel. The rolling capture device of the production set is made in the form of a drum equipped with blades, fixed on a horizontal axis kinematically connected to a drive. Blades are arranged with minimum gaps relative to an inner surface of a cylindrical shape jacket. The upper cylindrical part of the jacket is made with an opening. The axis is installed with the possibility of its rotation in a central part of side walls of the jacket, which in its lower part is equipped with a cut of rectangular form in plan with the possibility of displacement of blades in it and their introduction in thickness of the mineral. Blades are made forked and with flexures. Flexures of blades during their location in the lower part of a jacket are aligned towards the side opposite to direction of production tool displacement. At the same time the distance between forks of the blades is adopted as less than the minimum cross size of produced nodules. The cut in the jacket is made so that its edges are placed above useful thickness of a mineral. The jacket with the help of a receiving tray of narrowing cross section is connected to a suction nozzle of a soil pump. The soil pump is installed on cross beams of skis at the side of the jacket opposite to direction of production set displacement. The injection nozzle of the soil pump is connected to a perforated section of a pipeline fixed on a jacket and arranged above it, with the possibility of connection with a flexible discharge pipeline. The discharge pipeline is aligned in plan coaxially with an injection nozzle of a soil pump along a longitudinal axis of jacket symmetry. The production set is balanced in a transverse direction. Skis are fixed at two sides on side walls of the jacket and are made as V-shaped in cross section. The flexible pipeline is made from a combination of rigid rectilinear pipes and flexible inserts from elastic material with connection of adjacent pipes arranged along the perimetre of each pipe with round-link chains that perceive stretching forces.

EFFECT: increased efficiency of a complex, its simplified design, reduced material intensity, power intensity and cost, increased reliability of complex operation.
