A kind of seabed ore collecting vehicle and its method for collecting ore

Abstract

The invention discloses a submarine ore collecting vehicle and an ore collecting method thereof. The submarine ore collecting vehicle comprises water jet nozzles (1), an ore sucking hood (2), a spiral flow guiding plate (3), an ore slurry pump (4), a pressure-bearing ore storage tank (5), a relay cabin conveying pipeline (9) and an ore collecting vehicle cabin body (10), wherein the water jet nozzles (1) are closely arranged into a plurality of groups along the bottom of ore sucking hood (2) at certain vertically and transversely inclined angles; the spiral flow guiding plate (3) is embedded into the inner side of the ore sucking hood (2) along a spiral line; the ore slurry pump (4) is connected to the ore sucking hood (2) through an ore slurry pump pipeline, so that local negative pressure is formed in the ore sucking hood (2), and a vertical-axis whirlpool which flows upwards is formed under the flow guiding action of the spiral flow guiding plate (3); the ore slurry pump (4) conveys collected ores to a relay cabin through the relay cabin conveying pipeline (9), and is further connected with the pressure-bearing ore storage tank (5). The submarine ore collecting vehicle and the ore collecting method have the advantages of being environmentally friendly, efficient, lower in energy consumption, and reliable.

Description

technical field [0001] The invention relates to a seabed floating ore collecting device and a method for collecting ore, in particular to an environment-friendly, high-efficiency and energy-saving seabed ore collecting vehicle and a method for collecting ore. Background technique [0002] The ocean is the largest potential resource base on the earth that has not been fully understood and utilized by humans. In addition to offshore oil and gas resources and coastal mineral sands, the seabed is currently known to have commercial mining value as well as metal mineral resources such as polymetallic nodules, cobalt-rich crusts and polymetallic sulfides. These minerals are rich in nickel, cobalt, copper, manganese, gold and silver metals, etc., and the total reserves are dozens to thousands of times higher than the corresponding reserves on land. In 2013, my country officially obtained a Pacific cobalt-rich crust mining area. Obviously, the development of deep sea mineral resour...

Problems solved by technology

Due to the deep-sea terrain, deep-sea power, deep-sea communication, etc., the working range and working efficiency of this method are severely limited; the second is floating mining, which uses high-speed jetting water to blow up the seabed ore, and uses hydraulic or pneumatic power through pumps and pipelines. The ore is lifted from the seabed by means of this method, which is less affected by the deep sea environment, but consumes a lot of energy, and there is a lot of mud in the collected ore, which has a greater impact on the deep sea ecology

[0004] In summary, in order to improve the low production efficiency, high energy consumption, and serious damage to seabed ecology of the original seabed ore collection equipment, the present invention proposes a seabed ore collection vehicle and its method for collecting ore
