Description
Technical Field
The invention relates to submarine mineral collection, in particular to a submarine manganese nodule collector and a submarine manganese nodule collection method.
Background
The manganese nodule is a manganese ore produced by self-generation in the deep sea bottom, is also called as a polymetallic nodule, is an aggregate of iron and manganese oxides, and comprises the following components: manganese (27-30%), nickel (1.25-1.5%), copper (1-1.4%), cobalt (0.2-0.25%), and other components, including iron (6%), silicon (5%) and aluminum (3%). The manganese nodules are all from several microns to tens of centimeters in overall dimension, and the largest weight is dozens of kilograms. Manganese nodules are widely distributed on the surface layer of deep sea floor of 2000-6000 meters of water in the world ocean, the quality of the manganese nodules generated on the deep sea floor of 4000-6000 meters of water is the best, the distribution area of the North Pacific ocean is the widest, the reserves account for more than half of the world, the mineral resources belong to renewable resources, and the manganese nodules can grow up continuously.
The metal rich in manganese nodule is widely applied to various aspects of modern society, for example, the metal manganese can be used for manufacturing manganese steel, is extremely hard, can resist impact and wear, and is widely used for manufacturing tanks, steel rails, crushers and the like. The iron contained in the manganese nodule is the main raw material for steel making, the contained metallic nickel can be used for manufacturing stainless steel, and the contained metallic cobalt can be used for manufacturing special steel. The contained copper metal is largely used for manufacturing the electric wire. The metal titanium contained in the manganese nodule has small density, high strength and high hardness, is widely applied to the aerospace industry and is known as space metal.
At present, the exploitation of the manganese nodule mine at the bottom of the sea mainly depends on deep-sea ore-digging machines, and the ore-digging machines arranged at the bottom of the sea are like a huge dust collector, so that the minerals and the sludge at the bottom of the sea are sucked, filtered and ejected backwards. This mining mode of turning the sea floor bottom up, coupled with the enormous weight of tens of tons of mining machines, can be more damaging to the deep sea ecology than the undersea trawl technology known as "seiko-seiksun fishing". Meanwhile, the silt sprayed after filtration in the mining process also forms a large-scale silt plume which can increase the turbidity of the water body and block the filtering organs of organisms. Irregular turbulence disturbances on the seafloor may also further enlarge the plume. The losses caused to the exploitation of polymetallic nodules close to the submarine hydrothermal vents will likely be even greater.

The seafloor manganese nodule collector of claim 1, wherein the base body comprises a large arm I (11) and a large arm II (15), the large arm I (11) is located on the outer side of the wheel disc I (12), the large arm II (15) is located on the outer side of the wheel disc II (14), the rear ends of the large arm I (11) and the large arm II (15) are respectively hinged with the baffle plate III (9) and the baffle plate I (4), the front ends of the large arm I (11) and the large arm II (15) are respectively hinged with two ends of the rotating shaft (16), the middle part of the large arm I (11) is connected with the baffle plate III (9) through a connecting rod I (10), and the middle part of the large arm II (15) is connected with the baffle plate I (4) through a connecting rod II (19).
3. The seafloor manganese nodule collector of claim 2, wherein the rear ends of the large arm I (11) and the large arm II (15) are respectively provided with a rotary joint (5).
4. A method for collecting by using the collector of any one of claims 1-3, which is characterized by comprising the following steps:
s1, picking up manganese metal nodules on the surface of the seabed, and performing primary screening:
when the collector walks on the seabed, the collecting part rotates anticlockwise, manganese metal nodules on the surface of the seabed are collected in the rotating process of the L-shaped collecting teeth, the vertical bending ends of the L-shaped collecting teeth hook up the manganese metal nodules on the surface of the seabed, and because the gap between the L-shaped collecting teeth of two adjacent L-shaped collecting teeth is 3cm-7cm, the manganese metal nodules with the size smaller than the gap can penetrate through the gap between the two adjacent L-shaped collecting teeth, the manganese metal nodules with small size can not be collected, and the manganese metal nodules with large diameter are collected by the L-shaped collecting teeth, primary screening is realized;
s2, carrying out secondary screening on the manganese metal nodule along with the rotation of the acquisition part:
during the rotation process of the collecting part, manganese metal nodules with smaller sizes are still picked up by the L-shaped collecting teeth, along with the rotation of the L-shaped collecting teeth, the manganese metal nodules fall to the radials at the bottom of the L-shaped collecting teeth under the action of gravity, and because a gap exists between every two adjacent radials, the gap is 3cm-5cm, the manganese metal nodules with sizes smaller than the gap can fall from the gap between the two radials and fall onto the surface of the sea bottom again, secondary screening is achieved, and the manganese metal nodules with sizes larger than the gap stop between the two radials;
s3, collecting manganese metal nodules:
along with the continuous rotation of collection portion, the manganese metal tuberculosis through the second grade screening rotates to the top of bottom plate along with collection portion, under the action of gravity of manganese metal tuberculosis and the centrifugal force that the rotatory in-process of collection portion produced, manganese metal tuberculosis falls to on the bottom plate, and under the suction effect of suction mouth department, manganese metal tuberculosis takes out along pay-off passageway and flourishing feed bin in proper order, realizes the collection to manganese metal tuberculosis.
