Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] Such as figure 1 , figure 2 As shown, a deep-sea ore collection and separation device is mainly used for the collection and beneficiation of seabed raw ore, specifically including a self-propelled hull 1 and a sand pump 2, and two raw ore bins are separately arranged in the lower part of the hull 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 is provided with an ore outlet 712. Such as image 3 As shown, each set of rol...

The invention discloses a deep sea ore sand collecting and separating device. The device comprises a ship body, the ship body comprises a concentrate bin, a tailing bin and two raw ore bins, raw ores extracted by a sand extracting pump are crushed by a crushing machine, the crushed raw ores enter the first raw ore bin and are sent into the second ore bin through a first residue slurry pump, concentrate sands are selected from the raw ores through a magnetic separator and are sent into the concentrate bin through a concentrate conveyor device, and the sand extracting pump is powered off when the concentrator ores in the concentrate bin reach a certain position; and when the raw ores in the first ore bin are completely extracted into the second raw ore bin, the concentrate sands in the concentrate bin are sent into the first raw ore bin through a second residue slurry pump, and the tailing sands are conveyed to seabed far from a mining section through a tailing backfill pipe by using a tailing pump in order to realize onsite backfill. The device has the advantages of simple treatment of the tailings, no adverse effects on environment, saving of the transport capacity, reduction of the mining cost, full and accurate ore dressing of the raw ores, and effective avoiding of the waste of resources.
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...
