Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention lifts gold and other useful metals deposited or buried on the ocean floor (both deep and shallow) or spouted as hot water to a mother ship, and uses the seawater and useful metals etc. TECHNICAL FIELD The present invention relates to a method and a system for collecting seabed resources for separating and collecting marine resources, and an apparatus used for the same.

[0002]

2. Description of the Related Art Conventionally, there have been known inventions and devices of mining equipment for lifting manganese nodules on the seabed to a mother ship (JP-B-57-52479, JP-B-2-27517, and JP-B-60-19197). Further, there is known an invention of a submarine ore mining apparatus in which ore of an undersea ore deposit is converted into a slurry and transferred onto a mother ship via a pipeline and a pump unit (Japanese Patent Application Laid-Open No. 61-122393).

[0003]

SUMMARY OF THE INVENTION
The idea is to adopt a method of sucking up manganese nodules by jet jet at the bottom or middle point,
In the deep sea, high pressure jets are required. For example, the invention of Japanese Patent Publication No.
The goal is to mine in the deep sea of 000 m. In this case, not only must 400 kg / cm ^{2 to} 600 kg / cm ² of high pressure water be blown out from the nozzle, but also a large amount of 4000 m There is a problem that it must be sent up to 6000 m.

Although the manganese lump and the like raised on the mother ship as described above can be separated relatively easily, when the ore is crushed on the seabed to form a slurry, the ore is carried onto the mother ship together with an enormous amount of water. With respect to the separation of useful metals from the slurry obtained, no means for separation is shown. For example, when 10 tons of slurry is transported per second, enormous equipment is required for continuous processing, and seawater may be contaminated by drainage. However, there is a problem that the wastewater cannot be recycled like a land treatment facility. In particular, when the sampled metal is gold or the like, there has been a problem that the conventionally known separation method cannot be used at all.

[0005]

SUMMARY OF THE INVENTION The present invention utilizes a water pressure at the bottom of the sea to suction ore up ore and sand, and to perform magnetic separation to enable continuous large-volume treatment and to discharge wastewater to the sea. By returning to the proper depth, the problem of marine pollution caused by drainage was also resolved.

In other words, the invention of the method is that the resources on the seabed are flowed and conveyed into the mother ship via a suction pipe as mixed water with seawater, and the solids of the mixed water are converted into large particles and small particles during the flow of the mixed water. This is a method of collecting seabed resources, wherein the mixed water containing small particles is separated into useful particles and useless particles through a separation means, and the mixed water containing useless particles is returned to the sea through a dump pipe. . Further, the suction port of the suction pipe and the discharge port of the dump pipe are connected without an open port, and the separation means uses a combination of magnetic separation, screen separation, specific gravity separation or centrifugal separation. .

[0007] Next, the invention of the system comprises a means for exploring resources on the seabed, a means for mining, a means for transporting resources from the seabed to the mother ship, a means for separating the carried resources, and a dumping means for returning waste to the sea. Is a continuous processing line, which is a continuous processing line. The exploration means and mining means are provided with lighting means, photographing means, and means for sucking resources and water in the seabed moving housing. Then, the housing moving means is operated by the monitor in the mother ship on the image photographed as described above. Further, the separation means is a combination of a screen separation means for separating solids into large particles and small particles, and a magnetic separation means for separating small particles by magnetic strength, and the dumping means has an upper end at a drain port of the separation means. It is connected, and the other end is inserted deep into the sea with a dump pipe.

[0008] Further, the invention of the apparatus is characterized in that a suction pipe is provided at the center of a dome-shaped housing, and a plurality of lighting means and photographing means are provided at an upper portion of an outer wall of the housing.
A moving means for moving the housing back and forth, left and right is installed at a lower portion of the outer wall of the housing, and a lower end portion of the suction pipe forms a suction port, and is formed on an outer wall of the suction port.
A submarine resource collecting apparatus provided with a jet nozzle for excavation, wherein an electric cable and a pressurized water pipe are integrally attached to an outer wall of a suction pipe.

A solenoid coil for forming a magnetic field is disposed outside a ferromagnetic separation cylinder having one end connected to the suction pipe and the other end connected to the discharge pipe. A pipe device necessary for accommodating the pieces and for sending the mixed water to be separated and for sending the cleaning fluid for discharging the solid matter magnetized in the separation cylinder is provided in the suction pipe and the discharge pipe. It is a flow transport device for submarine resources characterized by being connected to each other, and a jet nozzle of water or a jet nozzle of a mixture of water and air for obtaining an ascending flow at the upper end of the suction pipe, to depressurize the inside and obtain a rising flow. It is an apparatus for providing fluidity for sucking seabed resources, which is installed.

In the above invention, if the upper part of the suction pipe is depressurized by jet injection in order to remove water of about 10 to 20 m at the upper end, the sea bottom becomes 1000 m.
However, even at 2000 m, an upward flow uniformly occurs in the suction pipe. For example, if water at the upper end of the suction pipe is sucked up at a speed of 2 m / s, the water in the suction pipe rises at a speed of 2 m / s. This rising speed rises to a speed at which the suction force and the flow resistance force match.

Therefore, if water of 10 m at the upper end of the suction pipe having a diameter of 0.5 m is sucked up in 10 seconds, a flow rate of 1 m per second can be provided. In this case, 0.
It can lift 270,000 tons of water a day, 67,000 tons of water. In the suction, if the water amount is set to 80%, the ore or sand becomes 13,000 tons. So 1 ton 2
In the case of 0 g of rich gold ore, 271 kg of gold particles can be lifted a day on the mother ship.

According to the present invention, a water pressure of, for example, 100 kg / cm ² is applied to the lower end of the suction pipe at a depth of 1,000 m, so that if the water pressure of 10 kg / cm ² at the upper end of the suction pipe is removed, the suction pipe will be in the suction pipe. Generates a water flow due to a differential pressure of 10 kg / cm ² , so that a suction force is generated and sand or ore can be sucked up.

According to the present invention, the sand or the like to be sucked or the ore can be sucked relatively easily if it is not solidified on the seabed, but part or all of the ore or the like is buried in the mud or partially buried in the mud. In the case of solidification, there are cases where crushing cannot be performed only by the suction force. In such a case, the water is crushed by a jet fountain and then sucked up. The pressure of the jet fountain in this case is the pressure required for crushing. If the soil is buried in the solidified mud, the mud is removed, and the desired ore is crushed and sucked up. Furthermore, in the case of hot water jetting, simply suctioning is sufficient.

In the present invention, it is necessary to move the position of the suction port of the suction pipe to collect useful ores and the like.
Since the state of the water bottom is unknown, appropriate lighting, shooting with a camera, and movement of the suction port are required. For example, when hot water is gushing out and the noble metals and other effective substances contained therein are sucked in and separated by the mother ship, a dome-shaped guide is connected to the end of the suction pipe, and at the fixed position, The hot water may be sucked in, but when excavation is required in a gold deposit or the like, a device capable of excavation and a device for moving the suction pipe end are required.

In the present invention, the shape of the housing is preferably a dome shape, and it is preferable that the housing can be moved back and forth, left and right, and that it is well-balanced and stable. it can.

If an electric cable and a pressurized pipe for sending pressurized water are provided outside the suction pipe in the present invention, the cable and the pressurized pipe are embedded in the thickness of the seawater-resistant material. If so, the suction pipe is reinforced, and no special reinforcing means needs to be added.

The useful metals in the above include not only noble metals such as gold and silver, iron, manganese and other metals, but also diamonds and other ores.

[0018]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention relates to a method in which gold or other useful metal or the like that is deposited or buried on the sea floor or existing as a vein is mixed with seawater, sucked and lifted into a mother ship.
This is a method for collecting seabed resources in which water and useful metals are separated and the remaining mixed water is returned to the bottom again.

Further, in order to realize the above-mentioned method, the present invention provides a seabed resource extraction system as a processing line connecting resource exploration means, mining means, resource transport means, separation means and waste mixed water dumping means.

Next, a dome-shaped housing is connected to the end of the water-absorbing pipe in order to efficiently suck the seabed resources, and a mixture of the seabed resources and water generated in the housing is sucked up by the water-absorbing pipe. A crushing device (jet fountain) for a seabed sedimentary layer or ore, a power device for moving the dome-shaped housing, a lighting device for monitoring and understanding the condition of the seabed on a mother ship, and a photographing device. And a submarine resource collecting apparatus characterized by the following.

Further, in order to suck the mixed water into the suction pipe as an apparatus of the present invention, the upper end of the suction pipe is set at 10 m or more.
There is a jet injection device for flowing 20 m of water. Next, as another apparatus, there is a separation apparatus for separating useful metals (for example, gold) from the mixed water continuously lifted.

Still another device is a mixed water dumping device that separates large solids from the mixed water, separates and collects useful metals and the like from the mixed water after the separation treatment, and returns the remaining mixed water to the sea.

The separation apparatus is a magnetic separation apparatus in which mixed water is fed into an installed parallel strong magnetic field to separate and magnetize useful metals and the like according to magnetism. For example, ferromagnetic particles such as iron and manganese are magnetized in a magnetic field of 1,000 to 10,000 gauss, and weak magnetic particles such as gold, silver and copper are 50,000 to 20 gauss.
This is based on means such as magnetizing with a magnetic field of 10,000 gauss.

The discarded mixed water in the above is deeply discarded into seawater by jet injection power. The dumping depth in this case needs to be a depth that does not cause seawater pollution.

[0025]

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings. If the sea bottom solid is sandy, if it is ore-like, it is crushed by pressurized water or the like and sucked into a suction pipe as mixed water with seawater (for example, 80% moisture). This suction involves pressurized water (for example, 5 kg / cm ² pressurized air may be mixed) in the mother ship at the upper end of the suction pipe.
Is generated by jet injection of a jet gas to generate an upward flow.

That is, when a negative pressure is generated inside the upper end of the suction pipe by jet injection, the pressure balance in the suction pipe is lost, and an upward flow is generated to supplement the pressure balance. This is due to the simple reason that the water level at the open water surface is the same. Then, when the water inside the upper end of the suction pipe is raised, a negative pressure is generated due to the rise, so that an upward flow is generated in the suction pipe to compensate for this. If an upward flow of, for example, 1 m per second is generated by the negative pressure, the mixed water is sucked at a speed of 1 m per second from the lower end of the suction pipe.

The mixed water sucked in as described above is lifted on the mother ship, and is subjected to magnetic separation after removing large grains. In this magnetic separation, for example, magnetic particles of iron sand or the like are magnetically separated by a magnetic field of 1,000 Gauss, and then gold and silver are magnetically separated by a magnetic field of 50,000 Gauss to 200,000 Gauss. Dump deep into the sea through.

The water depth of the dumping is set to a depth that does not cause marine pollution. However, since the suction pipe and the dumping pipe are continuous, high energy is not added for dumping.
It can be easily dumped at a pressure that breaks the water pressure balance at the end of the dump pipe.

In the magnetic separation, a plurality of separation cylinders are used in parallel, and when one of the separation cylinders takes out magnetically attached material, the other separation cylinder is operated so that the same flow velocity as the upward flow in the suction pipe is obtained. , The sorting operation can be continued.

In the above, the suction port of the suction pipe is
By appropriately moving, even in a very large mining area, it is possible to sequentially and rationally and efficiently mine.

The water inside the pipe 2a shows arrow 1
Since the flow starts as shown in FIG. 9 and the pressure in the section is reduced, the water pressure in the suction pipe 2 becomes unbalanced up and down.
Upflow like In this case, the horizontal pipe 2
If the cross-sectional area of the suction pipe 2 is the same as the cross-sectional area of the suction pipe 2, if a flow velocity of 1 m / sec is generated in the horizontal pipe 2a, the flow velocity at the lower end of the suction pipe 2 will be 1 m / sec. The flow velocity in the lower end of the suction pipe 2 is determined by adjusting the flow velocity in the horizontal pipe 2a in consideration of the quality.

An apparatus for separating large solid matter 72 and small solid matter 73 from the mixed water lifted on the mother ship 1 will be described with reference to FIGS.

A separating device 74 is provided on a part of the horizontal pipe 2a.
Intervene. The separation device 74 connects a separation pipe 75 to the horizontal pipe 2a, and separates the mixed water flowing straight from the horizontal pipe 2a as indicated by an arrow 76 into the separation pipe 75 at an angle. A net 77 is set up and the sorting net 7 is
The lower end of the pipe 7 is connected to the upper end of a branch pipe 78 for storing separated solids (large grains), and the lower end of the branch pipe 78 is connected to a storage tank 79 for the large solids 72. . The separation network 77 is provided downward as in the embodiment of FIG. 10 or upward as in the embodiment of FIG.
The point is to separate the large solid matter 72, and the shape and the specific structure of installation are not limited.

At the position where the separation net 77 is stretched as described above, the cross-sectional area is larger than the cross-sectional area of the horizontal pipe 2a, so that the resistance loss due to the separation net 77 is reduced as much as possible.

[0041]

[Embodiment 3] An embodiment of a system and apparatus for sucking and flowing seabed resources according to the present invention will be described with reference to FIGS.

According to the present invention, ferromagnetic particles and weak magnetic particles are separated from mixed water flowing in a magnetic field generated by an electromagnet, separately taken out of the system, and the remaining discarded mixed water is discarded into the sea. And a system for collecting seabed resources. Hereinafter, the collection of gold dust will be described.

That is, the mixed water sucked up by the suction pipe 2 is fed into the separation cylinder 24. In this case, the valves 25, 26, 27 and 28 in FIG.
When the first and the second are closed, the mixed water is indicated by arrows 34, 35 and 38.
As shown in FIG. The separation cylinder 24 is made of ferromagnetic stainless steel, and a plurality of sets of solenoid coils 37, 37a, 37b, 37c are sequentially arranged in parallel on the outside. The solenoid coils 37, 37a, 37
In b and 37c, the magnetic force increases as going to the downstream of the mixed water. For example, the solenoid coil 37 is 5,000 gauss, the solenoid coil 37a is 20,000 gauss, the solenoid coil 37b is 50,000 gauss, the solenoid coil 37c is 200,000 gauss, and the solenoid coils 37, 37a,
7b has substantially the same width, and the solenoid coil 37c has a width twice or more. Therefore, ferromagnetic iron sand (or gold dust attached to iron particles) magnetically attaches to a magnetic field of 5,000 gauss,
Weak magnetic placer (placer or placer with non-magnetic particles fixed)
Magnetically attaches to a magnetic field of 50,000 Gauss or 200,000 Gauss.

As described above, not only ferromagnetic iron sand but also weak magnetic gold dust is magnetically attached and separated from the mixed water. The remaining mixed water is sent to the dump pipe 22 via the valves 26, 27, 28 as indicated by arrows 40, 41, 59. When the gold dust magnetically attached to the free ferromagnetic material 64 (screw) in the separation cylinder 24 becomes saturated, the valves 25 and 27 are closed (for example, according to a timer instruction) and the valves 43 and 32 are closed.
When the valve 44 is closed and the mixed water is
55 and 56, the separation cylinder 24a enters the separation cylinder 24a.
As in the case of No. 4, the separated mixed water is magnetically magnetized with gold dust, and the
8, as shown by arrows 57, 58 and 59.
Sent to

On the other hand, the valves 31 and 29 are opened and the pump 45 is opened.
Is started, clean water for cleaning is supplied from the water tank 46 to the arrow 4.
7, 48, 49, 50 (for example, 5 kg / c
m ² ), and dumps the mixed water in the separation cylinder 24
Send to 2.

When the mixed water runs out, the valve 29 is closed, the valve 30 is opened, and the current of all the solenoid coils 37, 37a, 37b, 37c is cut off. After demagnetizing the magnetic fields of all the solenoid coils and losing the magnetic adhesion to the gold dust, the pump 4
When Shimizu is pumped by 5, the gold dust is transported along with Shimizu 4
Since the fluid flows like 9, 51, and 52 and is sent to the collection tank 53, one cycle of magnetic adhesion separation and collection of the gold dust is completed.

On the other hand, when the magnetic adhesion of the gold dust reaches the saturated state in the separation cylinder 24a (for example, determined by a timer), the valves 43, 32 are closed, and the valves 25, 26, 27 are closed.
Is opened, the mixed water is fed to the separation cylinder 24 in the same manner as at the beginning, the gold dust is magnetized in the separation cylinder 24, and the remaining mixed water is discharged to the dump pipe 22.

Next, the valves 23 and 33 are opened, and the valve 31 is opened.
Is closed, and the pump 45 is started.
Then, as shown by arrows 47 and 54, the mixed water sent into the separation cylinder 24a and remaining in the separation cylinder 24a as shown by arrows 61 and 50 is dumped into the dump pipe 22. If the mixed water in the separation cylinder 24a is cleaned in this way,
When the valves 23 and 30 are closed, the valve 44 is opened, and the power to all the solenoid coils 37, 37a, 37b and 37c is cut off, the magnetism is lost and the magnetic force of the separation cylinder 24a is lost. It is washed and accumulates in the collection tank 53.

The mixed water in the collection tank 53 collected as described above is separated into a solid and a liquid, and only gold dust is taken out and packed as appropriate.

In the above embodiment, since all the magnetically deposited gold in the separation cylinder 24 or 24a was simultaneously removed by the cleaning fluid, iron sand or the like was mixed in outside the gold dust. However, the magnetic field for each solenoid coil was individually adjusted. It can be demagnetized and each magnetic substance can be taken out individually.

For example, depending on the placer bed, when ferrous particles such as iron sand are contained in a large amount, the ferromagnetic particles magnetically adhere to a magnetic field of 5,000 Gauss, and the weak magnetic placer only has a magnetic field of 50,000 Gauss or more. Since only the magnetic field of 50,000 Gauss or more is demagnetized, only the gold dust can be collected and automatically separated from the ferromagnetic particles.

Next, the separating cylinder 24 in the above embodiment will be described. The separation cylinder 24 is rotatably fitted with a stainless steel separation cylinder 24 inside a ferromagnetic holding cylinder 63.
A number of stainless steel screws 64 are accommodated in the separation cylinder 24 as free ferromagnetic pieces. The capacity of the screw 64 is 5
0% to 90% (apparent volume), usually around 80%.

The solenoid coils 37, 37a, 37b, and 37c are mounted outside the holding cylinder 63, and the protection cylinder 65 is mounted outside the solenoid coils 37, 37a, 37b, and 37c. Pressurized pipe 66
And the other side is connected with a dump pipe 67. In the drawing, 68 and 69 are bearings, 70 is a pulley for rotating the separation cylinder 24, and 71 is each solenoid coil 37, 37
a, 37b, 37c, the inside of the separation cylinder 24 is partitioned,
The screw 64 is a partition net provided to maintain a predetermined position.
4 is a mesh that does not allow passage.

In the above-described embodiment, if the solenoid coils 37, 37a, 37b, 37c are energized, the screw 64
5 (a) and 5 (b) are magnetized, and the gold particles 52 are magnetically attached to the sharpened portions 64a of the screws 64 in FIG.
(C).

When the current of the solenoid coil 37 is cut off and the separation cylinder 24 is rotated, the magnetic force is suddenly lost. Therefore, if cleaning fluid is sent, the gold dust separated from the screw 64 is taken out of the separation cylinder 24 from the system. be able to.

As the free ferromagnetic piece used in the present invention, in addition to the screw 64, an elliptical body, a spherical body, or a small piece provided with a sharp ridge (or a projection) on an irregularly shaped linear body may be used. it can. However, since the magnetic force is reduced by rusting, it is preferable to use a ferromagnetic, non-small piece having a sharp outer surface, such as stainless steel. Since the sharp outer surface has a strong magnetic force, a weak magnetic material can be easily magnetized.

Further, at the time of degaussing, the separating cylinder is rotated, so that the degaussing speed is improved and the strong magnetic force (for example, 5
Even if the remanent magnetism after demagnetization temporarily becomes around 1,000 Gauss, the magnetically magnetized material is the same as having no magnetic attraction for a weak magnetic material. Absent.

According to the present invention, an upward flow is generated by jetting a pressurized fluid to the inside of the upper end portion of a suction pipe suspended on the seabed, and mixed water of seabed resources and seawater is passed through the suction pipe. The water is sucked up onto the mother ship, useful metals and the like are separated and collected from seawater, and the remaining mixed water is returned into the sea.

The above-mentioned resources can be easily collected.

Since the magnetic separation is performed, the magnetic substance in the resources can be separated and collected according to the magnetic strength.

According to the present invention, the resources on the seabed can be sucked up together with the seawater and separated at the same speed while flowing, so that there is an effect that the resources can be efficiently collected by the integrated automatic operation.
