METHOD OF TRANSFER OF MATERIAL OF NATURAL SHELF Russian patent published in 2002 - IPC

FIELD: transportation of loose fractions f materials. SUBSTANCE: transfer of material is effected via pipe line by means of centrifugal pump having impellers and electric motor. Centrifugal pump is positioned at angle relative to suction pipe line. Pump is secured to clutch ensuring wedge-shaped angle of delivery of pump jet from receiving manifold connected with said clutch when water flow is fed to it from pump and its section is regulated. Pump impellers are located between clutch and electric motor. Suction of water flow is effected from side of suction end of electric motor. Washing-out of soil and suction of pulp shall be effected at depth not exceeding 82 m of water layer. Winch with tractive cable is mounted on board water craft. Device for transportation of pulp is secured to tractive cable. Maximum depth of pulp suction depends on delivery of winch cable for washing- out soil and preventive cleaning of device, water flow from outlet branch pipe of pump is fed via pipe line fitted with adjustable valve. EFFECT: extended functional capabilities; reduced power requirements. 3 dwg
