Description

Technical Field

[0001] The present invention relates to a test platform in the technical field of deep - sea mining engineering and its usage method, in particular to a large - flow full - process land test platform for deep - sea mining ore flow that can solve the difficulty of connecting each platform under large scale and large flow, and its usage method. Background Art

[0002] With the gradual depletion of land mineral resources and the progress of technology, humans have begun to turn their attention to the deep - sea bed rich in many important minerals. The deep - sea bottom contains a large amount of metal resources, such as copper, nickel, cobalt, and rare - earth elements, etc., which are all indispensable raw materials for modern industry, especially for the manufacture of high - tech products. For example, these metals are widely used in electronic devices, electric vehicles, and renewable energy technologies. In addition, because traditional on - land mining activities are often accompanied by extensive environmental damage and ecological impacts, deep - sea mineral extraction may also reduce the pressure on the land ecological environment.

[0003] This test platform does not focus on the hydrodynamic problems of the entire deep - sea mining system, but focuses on studying the ore - flow problems in the whole process of deep - sea mineral resources from collection, transportation to separation. The research on the whole process of deep - sea ore flow is crucial for ensuring sustainability, helps to balance resource utilization and environmental protection, and has a profound impact on future energy and material security. Due to the high environmental pressure, low temperature, and insufficient light in the deep - sea environment, the ore flow not only needs to consider the structural damage caused by the ocean environment to the mineral extraction and transportation systems, but also needs to ensure the efficient extraction operation under deep - water pressure while effectively transporting and separating the ore. At present, the research on problems such as the whole - process collection, transportation, and separation of ore flow is still in the initial stage and is relatively scattered and independent. In addition, conducting large - scale system tests in the ocean is extremely costly and difficult.

[0004] Therefore, there is an urgent need to carry out large - scale full - process simulation test research on deep - sea mining ore flow through land - based indoor model tests. However, at present, the test systems available for the full - process simulation test research on deep - sea mining ore flow at home and abroad are still blank. Summary of the Invention

[0016] Step 2, select a suitable collection device according to the test conditions and arrange it on the replaceable collection device, install the acquisition auxiliary device according to the requirements of the collection head, and set the driving speed of the simulated mining vehicle to be simulated in the test and transmit it to the movable rail vehicle platform;

[0022] Second, it realizes large-scale and large-flow model tests, which can be used for pilot tests of deep-sea mining. By adopting a large-scale platform of 1:1 or 1:2, the influence of scale experiments on the results can be avoided, a large flow rate of 500 m3 / h can be achieved, the problems existing in the whole system under the condition of large-flow ore flow transportation can be reflected, the authenticity of the test can be restored, and the pain point that the current small-scale model test platform cannot conduct pilot tests of deep-sea mining is solved. The connection between the high-speed moving trolley and the static hose is realized using the storage tank, and the connection and stable feeding between the hose and the lifting hard pipe are realized using the relay station, effectively solving the conversion problems of dynamic and static, soft and hard, fluctuating and stable among the large-scale subsystems, and ensuring the transfer and effective control of the ore flow.

The control of variables such as nodules with different abundances (5 kg - 20 kg / m2), different collection devices (hydraulic, mechanical, hybrid), and different collection environments (flow velocity, sediment thickness) can be realized using the collection system. The control of variables such as different configurations (bimodal, unimodal), different angles (30 - 60°), and different structures (bonded, non-bonded) can be realized using the hose transportation system. The control of variables such as different particle sizes (10 mm - 100 mm), different concentrations (0 - 20%), different flow rates (100 - 500 m3 / h), and different gas injection positions (0 - 20 m) can be realized using the lifting and sorting system. The influence law of parameters on the local and even the whole system is studied by the method of controlling variables. Description of the Drawings

After opening, it can realize the circulation of the medium in different chambers, as Figure 11 shown.

[0039] In the present invention, the replaceable collection device 1-2 is arranged at the end of the collection pipeline 1-5, and the collection head can be replaced according to the test conditions; the collection auxiliary device 1-4 is arranged in the middle of the collection pipeline 1-5, including a high-pressure water jet system, an ore suction system, etc., and the equipment can be replaced according to the specific test condition requirements. The storage tank 1-7 is arranged on one side of the collection pool 1-1 for storing the collected ore. The inside of the storage tank 1-7 adopts a slope design, which can make the "ore-sediment-water" mixture flow to the designated central area. A storage tank discharge port 1-8 is set in this area, and a sludge pump 1-9 is arranged outside the storage tank discharge port 1-8, which can pump out the ore mixture from this port and send it into the hose conveying system.

[0040] The collection pool 1-1 is used to simulate the engineering environment of deep-sea mining. The movable rail car platform 1-3 is arranged above the collection pool 1-1 for simulating the driving of the mining vehicle at different speeds; the replaceable collection device 1-2 and the collection auxiliary device 1-4 are arranged on the movable rail car platform 1-3 for simulating the collection system of the deep-sea mining vehicle; the storage tank 1-7 is used to simulate the storage tank of the mining vehicle to store the collected ore.

[0041] The second track 2-2 is longitudinally installed at both ends of the fixing device 2-1. The moving platform 2-3 is installed on the second track 2-2 and can move longitudinally. The top surface of the platform is provided with a track for transverse movement. The hydraulic telescopic device 2-4 is installed on the top surface of the moving platform 2-3 and can move transversely. The simulation hose 2-5 is composed of a deformable hose. One end is connected to the first mud pump 1-9, the other end is connected to the feed inlet 3-1 of the lifting and sorting system, and the middle part is fixed to the top end of the hydraulic telescopic device 2-4 through the hose fixing device 2-6.

[0042] The fixing frame 2-1 is used to fix the position and carry the device. The moving platform 2-3 is installed on the second track 2-2 and can simulate the movement in the longitudinal direction of the hose buoyancy configuration; the hydraulic telescopic device 2-4 is installed on the top surface of the moving platform 2-3 and can simulate the movement in the transverse and vertical directions of the hose buoyancy configuration; the hose fixing device 2-6 plays a role in fixing the simulation hose 2-5 and the hydraulic telescopic device 2-4, and this system can simulate any configuration required in the test conditions.

[0043] The feed inlet 3-1 of the lifting and sorting system is arranged at the lower end of the relay cabin simulation device 3-2. The relay cabin is a giant funnel. The ore and sediment settle to the bottom of the funnel. There is a nozzle 3-22 at the bottom. The ore is pressed into the vertical lifting pipe through the screw conveyor 3-21 at the bottom of the hopper; an overflow hole 3-23 is arranged at the upper part of the hopper, and the water containing a certain amount of sediment can be discharged to the external water tank. The water pump of the water tank 3-25 is sent into the vertical lifting pipe 3-4 through the second mud pump 3-24 and mixed with the ore. In this way, the ore concentration and fluid velocity entering the vertical pipe can be controlled, and the connection transition from discontinuous collection to continuous transportation is realized. In addition, to prevent the situation that the excessive water pressure caused by the too large vertical height of the vertical pipe 3-4 flows back to the hopper 3-28, in the present invention, three chambers ABC are set through the valve 3-29 and the sealing partition 3-30, and the continuous transportation of the ore is realized through the differential speed alternation and exchange of the media between the chambers. As Figure 11 shown, the ore first enters chamber A. At this time, the first valve is opened and the second valve is closed. At this time, the water pressure acts on the partition between chambers BC, and the ore flows from the feed inlet 3-26 into chambers A and B. When chamber B is full of ore, the first valve is closed and the second valve is opened. At this time, the water pressure acts on the baffle between AB, and the ore flows from chamber B into chamber C. When chamber C is full of ore, the above steps are repeated. Since the screw conveyor 3-21 in chamber C transports slower than the free feeding speed, the replenishment of chamber B can be completed before the ore transportation in chamber C is completed, and further replenished to chamber C for stable screw transportation, so as to realize stable transportation under pressure. One end of the vertical lifting pipe 3-4 is connected to the relay cabin simulation device 3-2, and the other end is connected to the lower end of the sorting device 3-5, and the whole is vertically supported by the support frame 3-3.

[0044] The specific working method for conducting working condition tests through the test system for the overall transportation of minerals in deep-sea mining is as follows:

[0045] Arrange deep-sea simulated soil and simulated ore in the collection pool 1-1, and add a certain amount of water. Select a suitable collection device according to the test working conditions and arrange it on the replaceable collection device 1-2, and install the collection auxiliary device 1-4 according to the requirements of the collection head. Set the driving speed of the mining vehicle to be simulated in the test and transmit it to the movable rail vehicle platform 1-3, and adjust the fixed frame 2-1, the movable platform 2-3 and the hydraulic telescopic device 2-4 to the set positions to simulate the hose configuration required for the test, and then the test can be started.

[0046] After the test starts, the replaceable collection device 1-2 and the collection auxiliary device 1-4 pick up the simulated ore from the collection pool 1-1 and pass it through the collection pipeline 1-5 to the storage pool 1-7. When the ore collected in the storage pool 1-7 reaches the set weight, the first mud pump 1-9 operates, and pumps the ore in the storage pool 1-7 through the simulated hose 2-5 conveying system to the hopper 3-28 of the relay cabin simulation device 3-2, and realizes the connection and transition from discontinuous collection to continuous transportation through the relay cabin. The ore in the storage chamber is transported to the sorting device 3-5 through the vertical lifting pipeline 3-4 for sorting. After being sorted by the sorting device 3-5, the available ore and impurities such as simulated soil are separated for further processing.

[0047] This test system aims to simulate the entire process of collection and transportation in deep-sea mining engineering, but is not limited to this single test function. Various similar tests in the entire process of collection and transportation can add devices such as sensors and measuring instruments according to the test requirements to achieve the functional requirements of various tests.
