Problems solved by technology
[0006] An object of the present invention is to solve the problems of large waste of transport capacity, troublesome tailings treatment, and difficulty in effective mineral separation by magnetic separators in the existing deep-sea mining method, and provide a deep-sea mining system with simple tailings treatment and no damage to the mine. The adverse impact of the environment can save a lot of transportation capacity to reduce mining costs, and at the same time can make the magnetic separator effectively beneficiate
[0007] Another object of the present invention is to provide a deep-sea mining system that can fully and accurately select ore-separated raw ore, effectively avoid waste of resources

Embodiment Construction
[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0036] Such as figure 1 , figure 2 As shown, a deep sea mining system is mainly used for collecting and beneficiating seabed raw ore sand, specifically including a self-propelled hull 1 and a sand pump 2, and two raw ore bins 11, A concentrate bin 13 and a tailings bin 12. Similar to existing mining ships, the raw ore sand on the seabed is extracted by a high-power sand pump 2, and the sand pump is powered by a diesel engine. In addition, we need to install a crushing machine 7 on the hull. The crushing machine includes a shell 71, two sets of upper and lower rolling rollers 72 rotatably arranged in the shell, and an ore inlet 711 is set on the upper part of the shell. The lower part of the set of the ore outlet 712, and the ore inlet is located near the big end side of the two rolling rollers above. Such as image 3 As shown, each set of...

The invention discloses a deep sea mining system, which comprises a boat body, wherein the boat body consists of a fine ore cabin, a tailing sand cabin and two raw ore cabins; raw ore sand pumped by a sand pumping pump is pulverized by two conical milling rollers arranged in a pulverizing machine, then enters the first raw ore cabin and is conveyed into the second raw ore cabin through a first slag slurry pump; the raw ore sand passes through a magnetic separator so as to select out of the fine ore sand; next, the fine ore sand is conveyed into the fine ore cabin through an ore sand conveying device; when the fine ore sand in the fine ore cabin reaches a certain position, the sand pumping pump stops working; when the raw ore sand in the first raw ore cabin is totally pumped into the second raw ore cabin, the fine ore sand in the fine ore cabin is conveyed into the first raw ore cabin through a second slag slurry pump; the tailing sand is conveyed to the seabed far away from the mining region by a tailing sand pump through a tailing refilling pipeline to be refilled in situ. The deep tea mining system provided by the invention has the advantages that the processing on the tailings is simple; the adverse influence cannot be caused on the environment, so that the conveying capacity is saved; the mining cost is reduced; the raw ore can be subjected to sufficient and accurate ore dressing; the resource waste is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a deep sea ore collection and separation device 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 doc...
