Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0035] Such as figure 1 , figure 2 As shown, a deep-sea ore excavation device is mainly used for collecting and beneficiating seabed raw ore, and specifically includes a ship hull 1 floating on the sea surface, and a raw ore bin 11 and a tailing sand bin 12 are separately arranged in the lower part of the hull, 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 rolling rollers includes two cylindrical rol...

The invention discloses a deep sea ore sand excavator which comprises a ship body with a crude ore bin and a tailings bin, a sand pump, a crushing mill, a magnetic separation machine and a tailings pump, wherein the crushing mill comprises a shell, and upper and lower groups of crushing coupled rollers arranged in the shell; an eccentric distance is reserved between the center line of two crushing rollers in the upper group of crushing coupled rollers and the rotating axial line; a sand outlet of the sand pump is connected with an ore sand inlet of the shell through a pipeline; an ore sand outlet of the shell is connected with the crude ore bin through a pipeline; and concentrate sand separated by the magnetic separator is directly conveyed to a transportation ship through a helical conveyor and a belt conveyor, and tailings are conveyed into the tailings bin and conveyed by the tailings pump to the seabed which is far away from an exploitation area for on-site backfilling. The deep sea ore sand excavator is simple for treatment of tailings and does not have an adverse effect on the environment; a large amount of power can be saved to reduce the exploitation cost; the magnetic separator is of a long-strip structure, so that crude ore sand can be fully and accurately separated; and waste of resources is effectively avoided.
Description
technical field [0001] The invention relates to the technical field of mining, in particular to a deep-sea ore excavation device for collecting iron-containing raw ore 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 documen...
