Submarine mining engineering machinery

Abstract

The invention relates to submarine mining engineering machinery comprising a ship body provided with a concentrate bin, a tailing bin and two raw ore bins. A sand pump pumps raw ore sand on a sea floor to the first raw ore bin, and the raw ore sand is sent into the second raw ore bin through a first slag slurry pump; impurities are separated through a vibratile screen; concentrate sand selected by a magnetic separator is sent into the concentrate bin through a spiral conveyor and a belt conveyor; when the concentrate sand in the concentrate bin reaches a certain position, the sand pump stops working; and when the raw ore sand in the first raw ore bin is all pumped into the second raw ore bin, the concentrate sand in the concentrate bin is sent into the first raw ore bin through a second slag slurry pump, and tailing sand is conveyed by a tailing sand pump through a tailing backfilling pipeline to the sea floor far from a mining area to be backfilled in place. Treating to the tailings is simple and does not cause the bad effect on the environment, ore sand storage space can be fully utilized to save transport capacity and reduce the mining cost.

Description

technical field [0001] The invention relates to the technical field of mining, in particular to a marine mining engineering machine for collecting raw ore sand in the deep sea. Background technique [0002] With the dwindling of land mineral resources, people began to turn their attention to the sea, which is rich in mineral resources. In some areas, people found a large number of coastal placer, mainly titanium-containing magnetite. At present, the usual mining method It uses an offshore mining platform or a mining ship to pump the ore from the seabed to the mining platform or mining ship, and then uses the corresponding slurry pump to transport the collected raw ore to the transshipment transport ship. The transport ship will The raw ore is transported to the onshore concentrator for beneficiation to form concentrated ore that can be used for smelting. For example, a kind of " deep-sea collecting and distributing mining system " disclosed in Chinese patent document, annou...

AI Technical Summary

Problems solved by technology

[0006] An object of the present invention is to solve the problems of large waste of transport capacity and troublesome tailings disposal in the existing deep-sea mining mode, and provide a marine mining engineering machine whose tailings are easy to handle and will not cause adverse effects on the environment. And cocoa can make full use of ore storage space to save transportation capacity and reduce mining costs

[0007] Another object of the present invention is to provide a marine mining engineering machine capable of fully and accurately beneficiating raw ore sand in order to solve the problems of inaccurate ore separation and easy resource waste in deep-sea mining with magnetic separators. Effectively avoid waste of resources
