Problems solved by technology

At present, the deep-sea ore lifting device is composed of a pipeline. After the ore and seawater are mixed in a certain proportion, they are lifted from the seabed to the support ship on the sea surface through the pipeline. After the ore and seawater are separated on the sea surface support ship, the seawate

Abstract

The invention relates to a novel lifting system for dee-sea mining. The novel lifting system comprises a mining mechanism, a mine water lifting mechanism and a mine water separating mechanism; the mining mechanism comprises a mining cart which is arranged on the sea floor, a mining cart ore absorbing port is arranged on the front part of the mining cart, and a mining cart ore conveying pump is arranged on the rear part of the mining cart ore absorbing port; the mine water lifting mechanism comprises a high-pressure water feeding pump, a lifting main pipe, a water feeding pipe and a middle bin;the middle bin is connected with a fixed pile which is arranged on the sea floor bottom crust through a middle bin sea floor fixing cable rope, the middle bin is connected with the mining cart through a hose, and a floating body is arranged on the hose; the mine water separating mechanism comprises an ore storage tank, a mine water separating mechanism body and a clean water tank which are arranged on a sea surface mining vessel; and the ore storage tank is connected with the clean water tank through the mine water separating mechanism body. The novel lifting system for deep-sea mining has the advantages that hydraulic power is used for lifting, waste water lifted to the water surface can be fed back to the sea floor, meanwhile, a lifting pump on the sea floor can be driven to lift ore through the waste water, and the environment of the mining sea surface is protected.

Description

Technical field [0001] The invention belongs to the field of deep seabed ore mining, and particularly relates to a new type of deep sea mining lifting system. Background technique [0002] With the continuous exploitation of onshore mineral resources, mineral resources are increasingly depleted, resulting in an increasingly intensified contradiction between human demand for mineral resources and the shortage of mineral resources. The exploitation and utilization of seabed mineral resources is an important way to make up for the increasing shortage of onshore mineral resources. strategic initiatives and effective solutions. [0003] The ore lifting system is an important part of the deep sea mining system. The main function of the ore lifting system is to lift the ore on the seabed to the sea surface support ship. At present, deep-sea ore lifting devices are all composed of a pipeline. The ore and seawater are mixed in a certain proportion and lifted from the seabed through ...
