APPARATUS FOR LIFTING DEEP-SEABED MINERAL RESORCES

摘要

Disclosed is a lifting device for transferring of deep-seabed mineral resource. The present lifting device includes a shroud which prevents precipitation of a seabed mineral particle included in a slurry by maintaining a flow rate of the slurry passing through an inside of the lifting device above a critical settling velocity when a solid-liquid slurry composed of seabed mineral particles and seawater is press-transferred to a marine mining line, and is formed with a slurry flow path structure to effectively cool a motor unit by using seawater of low temperature.
