Technical Field
[0001] This invention relates to the fields of mineral engineering, marine engineering, environmental science, materials science and automation control, and specifically to a seabed resource mineral sorting system. Background Technology
[0002] Seabed mineral sorting is a crucial step in enriching valuable minerals and improving resource utilization, reducing transportation and smelting costs and minimizing pollutant emissions. However, existing technologies face numerous challenges. The high pressure and complex topography of the seabed environment lead to easy clogging of pumps and pipes in sorting equipment, insufficient sensor accuracy, and difficulty in adapting intelligent systems to deep-sea operations. The sorting process also easily generates sediment plumes, causing irreversible ecological impacts such as habitat destruction for marine life. Furthermore, the high research and development and operation costs of deep-sea sorting systems result in low returns on investment and weaker economic competitiveness compared to terrestrial mining. In addition, existing equipment lacks sufficient sorting precision, making it difficult to achieve refined sorting of seabed minerals with different densities, magnetic properties, and particle sizes, thus hindering resource utilization efficiency. Therefore, there is an urgent need for a low-cost, highly reliable, and environmentally friendly seabed mineral sorting device. Summary of the Invention
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a seabed resource mineral sorting system that integrates buoyancy, electromagnetic, and spiral sorting structures with a circulation system.

The system features a simple structure with clearly defined functions for each component, requiring minimal manpower and resources for maintenance, thus significantly reducing manufacturing, operation, and repair costs. It is also suitable for complex deep-sea operating environments.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises an upper buoyancy sorting structure, a middle electromagnetic sorting structure, a lower spiral sorting structure, and a circulation structure; the upper buoyancy sorting structure, the middle electromagnetic sorting structure, the lower spiral sorting structure, and the circulation structure are all installed on the hull platform; the upper buoyancy sorting structure is connected to the middle electromagnetic sorting structure, the lower spiral sorting structure is connected to the middle electromagnetic sorting structure, and the circulation structure is connected to the lower spiral sorting structure and the upper buoyancy sorting structure.
[0005] Furthermore, the upper buoyancy sorting structure includes a water supply pipe, which is mounted on a support frame using a fixing ring. The lower end of the support frame is fixed to the hull platform by a pier. A conical structure is located directly below one end of the water supply pipe, and a weir-shaped wall is set around the conical structure. The bottoms of the two are fixedly connected as one unit, and a flow pool is formed between the weir-shaped wall and the side wall of the conical structure. A water outlet channel is opened on the upper part of the weir-shaped wall. A spiral track is set on the outer wall of the weir-shaped wall. The upper end of the spiral track is connected to the water outlet channel, and the lower end is connected to the upper end of the pipe. The lower end of the pipe is connected to a collection chamber, which is installed on the hull platform. Several discharge holes are set at the bottom of the flow pool.
[0006] Furthermore, the central electromagnetic sorting structure includes a support column, which is located below the center of the weir-shaped wall. The support column is a hollow structure, with an AGV steering wheel installed inside. A slewing bearing is located below the center of the support column, and several hinged bearings are installed inside the slewing bearing. Each hinged bearing is connected to a telescopic electromagnetic device, and the AGV steering wheel controls the longitudinal rotation of the hinged bearings. The electromagnetic column of the telescopic electromagnetic device passes through a longitudinal slot in the outer wall of the slewing bearing and is located inside the flow-blocking wall. The flow-blocking wall is located around the upper part of the support platform, and several drainage holes are located inside the flow-blocking wall. The upper part of the structure features several ore passage slots arranged in a ring within the inner space of the flow barrier. These slots form a hollow cylindrical area, within which an AGV steering wheel is installed. This AGV steering wheel controls the horizontal rotation of the slewing bearing. The bottom ends of the ore passage slots are connected to a conveying pipe, which is inclined and connected at its end to a collection bin II. The collection bin II is installed on the ship's platform. Support platform I is mounted on the ship's platform using several hollow columns. Several drainage holes II are formed through the bottom of support platform I, and these drainage holes II are located within the annular space enclosed by the ore passage slots and the flow barrier.
[0007] Furthermore, the lower spiral sorting structure includes a funnel, which is installed at the bottom of the support platform one, and several drainage holes two are located inside the funnel at the upper position; the outlet of the funnel is connected to the spiral sorting track, and several slots are opened sequentially from top to bottom on the pipe wall of the spiral sorting track, with the diameter of the slots decreasing from top to bottom, and the slots are connected to several collection bins three by several pipes, and the collection bins three are installed on the hull platform; the spiral sorting track is installed on the hull platform by fixed support columns.
[0008] Furthermore, the circulation structure includes a second support platform. One side of the second support platform is installed at the bottom of the weir-shaped wall, and a water pump is installed on the other side. The output end of the water pump is connected to a water pipe, and the output end of the water pipe is connected to a water delivery pipe. The input end of the water pump is connected to the upper port of the vertical section of the branch pipe, and a valve is installed on this section of the pipe. The lower port of the vertical section of the branch pipe is connected to a funnel-shaped suction device, which is installed in a water storage tank.

The horizontal section of the branch pipe is located below the valve, and the output end is located above the storage tank, which is installed on the hull platform.
[0009] Furthermore, a staircase is installed on the hull platform.
[0010] The working principle of this invention is as follows: Materials retrieved from the seabed are introduced into the upper buoyancy sorting structure via a water pipe. As the materials enter the flow tank, substances denser than water settle, while those less dense float. These float on the surface and enter the spiral track through the outlet channel, flowing into the collection chamber one via a pipe. Substances denser than water enter the baffle wall in the middle electromagnetic sorting structure through the discharge hole one, achieving sorting. In the middle electromagnetic sorting structure, a telescopic electromagnetic device begins operation. This device contains a sensing device and an adsorption device. If minerals are detected, they are adsorbed. If no minerals are detected, the telescopic electromagnetic device rotates longitudinally under the drive of the AGV steering wheel, slowly lifting upwards. Simultaneously, the sensing and adsorption devices in the telescopic electromagnetic device deactivate. Utilizing the telescopic extension and retraction of the electromagnetic device, minerals are... The material detaches and enters several ore passing through slots, then falls into collection bin two via the ore conveying pipe. The remaining material in the baffle wall enters the lower spiral sorting structure through the discharge hole two. In the lower spiral sorting structure, the material enters the spiral sorting track through a funnel, and then enters the corresponding pipe through several slots with decreasing diameters from top to bottom, finally falling into the corresponding collection bin three, achieving graded sorting. Each slot has a different function, and based on gravity, centrifugal force, and friction, the size range of minerals received by each slot is divided to ensure fine mineral sorting. Water flowing out from the end of the spiral sorting track enters the water storage bin in the circulation structure. The valve is opened, and the water is pumped to the water conveying pipe and enters the upper buoyancy sorting structure for re-sorting. After sorting is completed, the valve is closed, and the remaining material in the water storage bin enters the storage bin.

Utilizing the telescopic extension and retraction of the telescopic electromagnetic device 2-4, minerals fall into the flow tank.

The function of each slot... The size range of minerals received by each slot is divided according to gravity, centrifugal force, and friction to ensure fine mineral sorting. Water flowing out from the end of the spiral sorting track 3-2 enters the water storage tank 4-1 in the circulation structure 4. The valve 4-8 is opened, and the water is pumped by the water pump 4-2 to the water delivery pipe 1-1 and enters the upper buoyancy sorting structure 1 for re-sorting. After sorting is completed, the valve 4-8 is closed, and the remaining material in the water storage tank 4-1 enters the storage tank 4-7.
