Deep-sea ore transport system relay warehouse

Abstract

The invention discloses a deep-sea ore transport system relay warehouse. The deep-sea ore transport system relay warehouse comprises an upper warehouse body, a lower warehouse body, a warehouse connection bolt assembly, a fluidic generator, and a fluidic generator connecting bolts. Polymetallic nodules reserved under the sea are collected by an ocean mining machine and are transported to the relaywarehouse by an ore pulp conveyor hose after mud removal and crushing; and a lifting rigid pipe connected with a pulp pump is directly inserted into the bottom end of the relay warehouse, the position, close to the bottom end of the relay warehouse, of the lifting rigid pipe is provided with a bell-shaped suction inlet, and the fluidic generator is arranged on the relay warehouse under the bell-shaped suction inlet. When the pulp pump works, the bottom end of the bell-shaped suction inlet generates upward water jet due to negative pressure, and ore particles deposited at the bottom of the relay warehouse are sucked into the lifting rigid pipe under the dual action of the suction of the pulp pump and the jet flow water hammer and are transported by a pipeline to a surface mining ship. Thedeep-sea ore transport system relay warehouse is simple in structure and convenient to use, and effectively solves the problem that a pipe outlet is plugged due to that fact that a deep-sea ore transport system is prone to depositing materials at the suction inlet of the lifting rigid pipe.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a relay bin of a deep-sea ore conveying system for collecting ore in the deep sea. Background technique [0002] With the continuous development of the world economy, the demand for mineral resources is also increasing. Excessive resource development has caused the earth's land mineral resources to become increasingly exhausted. In order to meet the needs of human survival and development, countries around the world have set their sights on mineral resources since the last century. The vast ocean; the function of the deep-sea ore conveying system is to lift the ore collected from the seabed to the mining ship on the sea surface, which is one of the core technologies of deep-sea mining; for the research on its ore conveying method, the United States, Germany, France, Japan, South Korea, etc. A lot of theoretical analysis and experimental exploration have been done, and it is genera...
