Description

Technical Field

[0001] The present invention relates to the field of deep seabed mining equipment, and in particular to a slurry lifting unit, a slurry lifting device, a mining device and a mining system, which are systems for lifting minerals mined from the deep seabed to the sea surface. Technical Background

[0002] With the continuous exploitation of land mineral resources, land mineral resources are becoming increasingly depleted, while human demand for minerals is increasing day by day. The contradiction between mineral depletion and increased demand is becoming increasingly prominent, and there is an urgent need to seek new mineral resources to make up for the shortage of land mineral resources. As we all know, the ocean area accounts for two-thirds of the earth's area, and obtaining new mineral resources from the seabed is one of the feasible ways at present.

[0003] The ore lifting device is an important part of the deep-sea mining system. Its function is to lift the ore from the seabed to the support ship on the sea surface. At present, it is difficult to lift the minerals from the deep seabed to the sea surface. Foreign countries have tried many methods for deep-sea mining, and domestic deep-sea mining has also been studied in recent years, from the initial drag-type mining, continuous chain bucket mining, automatic shuttle mining, to deep-sea centrifuge pumping mining in recent years, but the technology is not mature enough. The most promising method for deep-sea mining is the hydraulic pipeline lifting method, that is, the ore and seawater are mixed in a certain proportion and lifted from the seabed to the support ship on the sea surface through a pipeline, but the poor structure causes slag accumulation, which reduces the efficiency. In addition, because some very fine particles will still remain in the separated seawater, if it is directly discharged into the sea surface, there is a situation of damaging the ecological environment. Although the deep-sea centrifuge pumping method has improved the efficiency of mining to a certain extent, it cannot be done in one step and requires multi-stage transportation. In addition, due to the wear of the slurry, the blades are easily damaged, the life is short, and the reliability and economy are not high. Some diaphragm pumps have low efficiency due to small displacement, large stroke, easy fatigue damage of diaphragms, etc. Therefore, deep-sea mining urgently needs a rising device and system with high efficiency, long life, small displacement fluctuation, and environmental protection to improve the efficiency of deep-sea seabed minerals and ensure the economic feasibility of mining. Summary of the invention

[0030] A mining system uses the slurry lifting unit or the slurry lifting device or the mining device.

[0031] The present invention has the following advantages and beneficial effects:

[0032] 1. The seawater pipe of the present invention transports seawater and the mineral source pipe transports ore pulp. The ore pulp is fed into and discharged from the ore pulp pump group. The ore pulp pump group comprises two pump housings. The pump housings are each provided with a movable diaphragm in the pump housing. The diaphragm divides the pump housing into a seawater chamber and an ore pulp chamber isolated from each other. The deformation of the diaphragm drives the linkage mechanism to move up and down, and the seawater is periodically introduced into the two pump housings respectively. As long as the seawater chamber of one of the pump housings is introduced into the seawater chamber, the volume of the seawater chamber becomes larger and the diaphragm is deformed to reduce the volume of the ore pulp chamber, and the ore pulp in the ore pulp chamber is discharged. At the same time, the linkage mechanism drives the diaphragm of the other pump housing to deform, so that the volume of the seawater chamber of the pump housing becomes smaller and the volume of the slurry chamber becomes larger. The slurry is input into the slurry chamber. In the two pump housings, one pump housing is always kept to discharge the slurry and the other pump housing is kept to feed the slurry, so that the feeding and discharge of the slurry are uninterrupted and the displacement operation is stable with small fluctuations. The pump housing of the present invention replaces the traditional centrifuge pump to discharge the slurry, which will not cause slag accumulation and short service life in the seawater chamber in the pump housing. Since the two pump housings discharge the slurry in a circulating manner, the efficiency is improved, and the two pump housings discharge the slurry in a cyclic manner.

[0033] 2. The first pump housing and the second pump housing of the present invention are sealed and slidably connected to the force transmission rod, the upper end of the force transmission rod is connected to the guide rope, and the lower end of the force transmission rod is connected to the diaphragm, and the diaphragm is embedded in the first pump housing and the second pump housing. When water flows through the first seawater branch pipe to move the diaphragm downward, the force transmission rod and the guide rope are driven downward to discharge the slurry in the first pump housing through the slurry pipe. Similarly, when water flows through the second seawater branch pipe, the diaphragm moves downward to discharge the slurry in the second pump housing through the slurry pipe.

[0034] 3. The diaphragm of the present invention divides the interior of the first pump housing and the second pump housing into a seawater chamber and a slurry chamber. The seawater chamber is connected to the first seawater branch pipe and the second seawater branch pipe, and the slurry chamber is connected to the slurry pipe. The diaphragm further separates the interior of the first pump housing and the second pump housing. As long as the volume of the seawater chamber increases, the diaphragm deforms to reduce the volume of the slurry chamber, and the slurry in the slurry chamber is discharged from the slurry pipe. As long as the volume of the seawater chamber decreases, the diaphragm deforms to increase the volume of the slurry chamber, and the slurry enters the slurry chamber from the slurry pipe, and the water in the seawater chamber is discharged from the main drainage pipe.

[0035] 4. The diaphragm of the present invention is clamped at the lower end of the force transmission rod, and the deformation of the diaphragm facilitates the movement of the guide rope.

[0036] 5. The guide rope of the present invention is overlapped on the guide device. The guide rope rises or falls under the drive of the pressure rod. The guide rope slides on the guide device or drives the guide device to rotate, thereby reducing friction and facilitating the smooth discharge of the slurry.

[0037] 6. The first slurry branch pipe of the present invention has a first slurry inlet valve and a first slurry discharge valve, and the second slurry branch pipe has a second slurry inlet valve and a second slurry discharge valve. The slurry pipe is located between the first slurry inlet valve and the first slurry discharge valve, and the slurry pipe is located between the second slurry inlet valve and the second slurry discharge valve. As long as the slurry inlet valve is opened and the slurry discharge valve is closed, the slurry enters the slurry chamber from the slurry pipe. As long as the slurry inlet valve is closed and the slurry discharge valve is opened, the slurry is discharged from the slurry chamber through the slurry pipe.

[0038] 7. In the present invention, one end of the first slurry branch pipe and the second slurry branch pipe are connected to the ore source inlet pipe, and the other end of the first slurry branch pipe and the second slurry branch pipe are connected to the ore source discharge pipe, the ore source inlet pipe allows the slurry to enter, and the ore source discharge pipe allows the slurry to be discharged.

[0039] 8. The diaphragms inside the first pump housing and the second pump housing of the present invention are made of EVA, which is conducive to the deformation of the diaphragms and the separation of the seawater chamber and the slurry chamber.

[0040] 9. The present invention mainly utilizes the power source on the hull to inject power seawater into the mineral lifting unit of the seabed mining device to drive the slurry lifting unit. Multiple slurry lifting units form a mineral lifting device, thereby forming a seabed mineral lifting device with large displacement, small fluctuation, long life, reliable operation, high efficiency and self-priming ability.

[0041] 10. The inner wall of the pump housing of the present invention has a slope, and the slope gradually increases from the mineral source pipe toward the diaphragm, which is beneficial to the extrusion and discharge of the slurry from the diaphragm to the mineral source pipe.

[0068] Example 4

[0069] The specific working principle of the slurry lifting unit of the present invention is as follows:

[0070] like Figure 3-4 As shown, pressurized seawater enters the seawater main pipe 10 from the seawater inlet pipe 1 , and then enters the first seawater branch pipe 11 and the second seawater branch pipe 21 .

[0071] The first water inlet valve 12 is opened, the first drain valve 13 is closed, the second water inlet valve 22 is closed, the second drain valve 23 is opened, the first slurry inlet valve 16 is closed, the first slurry discharge valve 18 is opened, the second slurry inlet valve 19 is opened, the second slurry discharge valve 20 is closed, the hull power water pump drives the seawater, and the driven high-pressure seawater enters the first seawater branch pipe 11 and the first pump casing 5. The volume of the first seawater chamber 6 in the first pump casing 5 increases, pushing the flexible diaphragm 9 to move downward, and correspondingly the volume of the first slurry chamber 7 in the first pump casing 5 decreases, and the first slurry chamber in the first pump casing 5 is discharged through the first slurry pipe 8 and the first slurry branch pipe 15. The slurry in chamber 7 enters the ore source discharge pipe 29. Since the diaphragm 9 in the first pump housing 5 moves downward and drives the guide rope 2 to move downward through the force transmission rod 4, the force transmission rod 4 connected to the second pump housing 24 drives the diaphragm 9 in the second pump housing 24 to move upward, and the volume of the second seawater chamber 25 in the second pump housing 24 is reduced. The seawater in the second seawater chamber 25 in the second pump housing 24 is discharged so that the seawater is discharged from the drainage main 28. The volume of the second slurry chamber 26 in the second pump housing 24 is increased, and the slurry is sucked into the slurry from the second slurry branch pipe 17 and enters the second slurry chamber 26 in the second pump housing 24 through the second slurry pipe 27.

[0072] After the above work is completed, the first water inlet valve 12 is closed, the first drain valve 13 is opened, the second water inlet valve 22 is opened, the second drain valve 23 is closed, the first slurry inlet valve 16 is opened, the first slurry discharge valve 18 is closed, the second slurry inlet valve 19 is closed, and the second slurry discharge valve 20 is opened. The driven high-pressure seawater body enters the second seawater branch pipe 21 and the second pump casing 24. The volume of the second seawater chamber 25 in the second pump casing 24 increases, pushing the flexible diaphragm 9 to move downward, and correspondingly, the volume of the second slurry chamber 26 in the second pump casing 24 decreases, and the slurry in the second slurry chamber 26 in the second pump casing 24 is discharged into the ore source discharge pipe 29 through the second slurry pipe 27 and the second slurry branch pipe 17. The diaphragm 9 in the second pump housing 24 moves downward and drives the guide rope 2 to move downward through the force transmission rod 4. The force transmission rod 4 connected to the first pump housing 5 drives the diaphragm 9 in the first pump housing 5 to move upward, and the volume of the first seawater chamber 6 in the first pump housing 5 is reduced. The seawater in the first seawater chamber 6 in the first pump housing 5 is discharged so that the seawater is discharged from the drainage main 28. The volume of the first slurry chamber 7 in the first pump housing 5 is increased, and the slurry is sucked from the first slurry branch pipe 15 and enters the first slurry chamber 7 in the first pump housing 5 through the first slurry pipe 8, thereby realizing a cycle of a basic mineral rising unit. All valves in this embodiment are also automatically (electrically) controlled or manually controlled valves.

[0073] Example 5

[0074] Multiple slurry lifting units and connecting devices are combined into a slurry lifting device 01, and multiple slurry lifting units are connected in series and / or in parallel (such as Figure 2 , 5 As shown), the slurry lifting device 01 is connected to the slurry receiving and processing device 03 directly or indirectly, and the slurry lifting device 01 is connected to the mining device 02 (as shown in FIG. Figure 1 As shown), the mining device 02 collects slurry from the deep sea and sends the slurry to the slurry lifting unit or the slurry lifting device 01. The guide device of the slurry lifting device 01 is fixed on the connecting device, which can be a frame structure. All guide devices and pump housings are fixed on the frame structure. The connecting device is directly or indirectly fixedly connected to the slurry receiving and processing device 03 (waterproof pipe or mining ship or floating platform), wherein the indirect connection refers to the fixed connection between the connecting device and the waterproof pipe, and the waterproof pipe is fixedly connected to the slurry receiving and processing device 03, so that the slurry lifting unit completes the slurry lifting work. Generally speaking, the ore source discharge pipe 29 is connected to the waterproof pipe, and the slurry is lifted to the slurry receiving and processing device 03 (waterproof pipe or mining ship or floating platform) and other equipment through the ore source discharge pipe 29 and the waterproof pipe. The seawater in the seawater pipe is pressurized and is pumped into the seawater pipe. The linkage mechanism moves with the rise and fall of the diaphragm 9, and the guide rope 2 rises and falls with the rise and fall of the force transmission rod 4.

[0075] Example 6

[0076] like Figure 2 , 5 The slurry lifting device shown ( Figure 2 , 5 The dotted line box is the slurry lifting unit. Figure 3-4 The slurry lifting units are combined and together with the connecting device form a slurry lifting device 01, and power seawater is injected into the slurry lifting units on the seabed to drive multiple slurry lifting units to operate, thereby forming a deep-sea mining slurry lifting device with large displacement, small fluctuation, long life, reliable operation, high efficiency and strong self-priming ability.

[0077] Example 7

[0078] like Figure 2 , 5 In the slurry lifting device shown, pressurized seawater enters the slurry lifting unit through the seawater inlet pipe 1, and the seawater in the pump housing is discharged from the drainage main pipe 28 to the deep sea instead of being discharged to the sea surface, thereby achieving environmentally friendly discharge, and the mined slurry enters from the ore source inlet pipe 14, and the mined slurry enters from the ore source inlet pipe 14, and the slurry is discharged from the ore source discharge pipe 29. The combination of multiple mineral lifting units increases the displacement of the slurry, the deformation of the diaphragm 9 and the separation of the pump housing by the diaphragm 9 make the in and out operation of the slurry stable and with small fluctuations, the slurry does not enter the seawater chamber, and there will be no slag accumulation in the seawater chamber, which makes the pump housing have a long service life, reliable operation and high efficiency, and the drainage main pipe 28 discharges the seawater body into the deep sea instead of discharging it to the sea surface, which will not cause environmental pollution.
