Description

Technical Field

[0001] The present invention relates to the technical field of deep sea mining technology, and in particular to an ore processing system and method for a deep sea mining vehicle. Background Art

[0002] Seabed mining is the work of mining seabed mineral resources, mainly collecting minerals deposited on the seabed surface (polymetallic nodules, polymetallic sulfides, cobalt-rich crusts, etc.). The mining process involves the excavation of seabed ore bodies and the underwater lifting and transportation of ore. In the process of deep-sea mineral mining, the collection system will collect ores of different sizes mixed with mud and sand at the same time. The lifting system transports the ore from the storage box of the mining vehicle to the surface mining mother ship by pneumatic or hydraulic means.

[0003] In the prior art, the collected ore is crushed to control the maximum size of the ore entering the lifting system and reduce the risk of blockage in the lifting system. However, the ore may be over-crushed during the crushing process. At the same time, small-sized ore and mud will be lost in the subsequent process flow after being lifted onto the mining mother ship, resulting in low operating efficiency of the entire mining system. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned existing production technologies, the applicant provides an ore processing system and method for deep-sea mining vehicles, thereby controlling the ore particle size to meet the requirements of the lifting system while reducing the content of small particle ore and mud, thereby improving the operating efficiency of the entire mining system.

[0010] A power pipeline is connected to the end of the crushing pipeline, and the end of the power pipeline is connected to the confluence port. The power pipeline is used to receive the ore from the crushing pipeline to form a second small-sized fluid, and transport the second small-sized fluid to the confluence port to mix with the first small-sized fluid to form a pre-treated small-sized fluid in the transport pipeline;

[0011] A second screening structure is arranged at the end of the conveying pipeline, and is used to screen the pretreated small-size fluid into particles less than or equal to the target size lower limit and ores larger than the target size lower limit. The ores larger than the target size lower limit are collected by the silo of the mining vehicle.

[0012] As a further improvement of the above technical solution:

[0013] A discharge port is provided at the bottom of the silo, and the discharge port is used to communicate with a feed port of a lifting system. The silo continuously supplies ore of a size that meets the requirements to the lifting system.

[0016] The first filter is a perforated plate structure, and the lower edge of the first filter is flush with the edge of the first branch port.

[0017] The power pipeline includes a manifold, a water pump is installed at one end of the manifold, the other end of the manifold is connected to the manifold port, an ore inlet is provided on the side wall of the manifold, the ore inlet is connected to the end of the crushing pipeline for receiving crushed ore, the water pump provides water flow into the manifold to mix with the crushed ore to form the second small-sized fluid, and transports the second small-sized fluid into the manifold port.

[0018] The second screening structure comprises a second screening chamber, the second screening chamber is provided with a second inlet, a second outlet and a second branch port, the second inlet and the second outlet are arranged opposite to each other and the flow direction of the fluid is consistent with the flow direction of the fluid in the conveying pipeline, and the second branch port faces downward and is connected to the inlet of the silo;

[0019] A second filter is disposed at the second outlet, and the second filter is adapted to the lower limit of the target size.

[0020] The second filter is a perforated plate structure, and the lower edge of the second filter is flush with the edge of the second branch port.

[0028] The beneficial effects of the present invention are as follows:

[0029] The invention has a compact and reasonable structure and is easy to operate. The ore in the collected ore fluid that exceeds the capacity of the lifting system is screened out through the first screening structure and then crushed to avoid excessive crushing of the ore. The ore is then re-collected into the conveying pipeline through the power pipeline and conveyed to the silo. At the entrance of the silo, the second screening structure is used to screen out the overly small ore and sediment, and the ore within a certain size range is retained, thereby achieving the control of the ore size to meet the requirements of the lifting system while reducing the content of small-sized ore and sediment, thereby improving the operating efficiency of the entire mining system.

[0030] At the same time, the present invention also has the following advantages:

[0031] (1) The power pipeline not only realizes the transportation of crushed ore by overcoming gravity, but also is used to enhance the situation of insufficient power inside the conveying pipeline due to the resistance loss of the first screening structure, so that the ore fluid in the conveying pipeline direction is continuously transported.

[0032] (2) Through the coordinated operation of the first screening structure, the second screening structure, the crushing pipeline, the power pipeline and the conveying pipeline, the size of the ore entering the silo is controlled within a set range, thereby preventing the ore entering the lifting system from being too large or too small, avoiding excessive crushing of ore of moderate size, and achieving the final desludging and desanding of the ore.

[0046] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0047] Embodiment 1:

[0048] like Figure 1-Figure 2 As shown, the ore processing system for a deep-sea mining vehicle of this embodiment includes a first screening structure 2 , a crushing pipeline 8 , a conveying pipeline 4 , a power pipeline 7 , and a second screening structure 5 .

[0049] The first screening structure 2 is connected to the outlet of the collecting device 1 of the mining vehicle, and is used to receive the ore fluid from the collecting device 1, and screen out the ores larger than the upper limit of the target size in the ore fluid to form a first small-size fluid.

[0050] Specifically, the collection device 1 includes a collection head 11 for directly collecting seabed ore and a collection pump 13 for providing power. The collection pump 13 is installed on the frame of the mining vehicle. One end of the collection hose 12 is connected to the collection head 11, and the other end is connected to the inlet of the collection pump 13. The outlet of the collection pump 13 is connected to the first inlet 21 of the first screening structure 2. Generally, there are multiple sets of the collection device 1, such as Figure 2 As shown; the value of the upper limit of the target size is determined according to the lifting capacity of the lifting system, and oversized ores are screened; the first small-size fluid includes ores and sediment other than oversized ores.

[0051] The crushing pipeline 8 is connected to the first screening structure 2 and is used to receive ores larger than the upper limit of the target size and crush them.

[0052] Specifically, the screened out oversized ores enter the crushing pipeline 8 to be crushed, and the size of the crushed ores is less than or equal to the upper limit of the target size.

[0053] The delivery pipeline 4 is connected to the first screening structure 2 and is used for delivering the first small-sized fluid. A confluence port 3 is provided in the middle of the delivery pipeline 4 .

[0054] Specifically, the conveying direction of the fluid in the conveying pipeline 4 is from the first screening structure 2 toward the second screening structure 5 .

[0055] The power pipeline 7 is connected to the end of the crushing pipeline 8, and the end of the power pipeline 7 is connected to the confluence 3. The power pipeline 7 is used to receive the ore from the crushing pipeline 8 to form a second small-sized fluid, and transport the second small-sized fluid to the confluence 3 to mix with the first small-sized fluid to form a pre-treated small-sized fluid in the transport pipeline 4.

[0056] Specifically, the ore size in the small-size fluid after pretreatment is smaller than or equal to the target size and contains sediment.

[0057] The second screening structure 5 is arranged at the end of the conveying pipeline 4, and is used to screen the pre-treated small-size fluid into particles less than or equal to the target size lower limit and ores larger than the target size lower limit. The ores larger than the target size lower limit are collected by the silo 6 of the mining vehicle.

[0058] Specifically, the value of the lower limit of the target size is determined according to the particle size of the ore that is easily lost in the subsequent process flow, and particles smaller than the lower limit of the target size include ore and mud; a discharge port 65 is provided at the bottom of the silo 6, and the discharge port 65 is used to communicate with the feed port of the lifting system, and the silo 6 continuously supplies ore of a size that meets the requirements to the lifting system; the lifting system is a pipeline system for transporting ore by pneumatic or hydraulic means, and the lifting system transports the ore from underwater to the surface mining mother ship through the pipeline.

[0059] The deep-sea mining vehicle ore processing system of this embodiment processes the ore fluid collected by the collection device 1 and then sends it to the silo 6, so that the size of the ore collected by the silo 6 is within the range from the upper limit of the target size to the lower limit of the target size. In the processing system, the first screening structure 2, the conveying pipeline 4 and the second screening structure 5 are sequentially connected in a straight line direction to form a main flow path. The first screening structure 2, the crushing pipeline 8 and the power pipeline 7 are a branch path of the main flow path, and the oversized ore is crushed and then re-entered into the main flow path.

[0060] In the prior art, when the collected ore is processed, all of it enters the crusher, which will cause the ore to be over-crushed, resulting in too much small-sized ore, resulting in low operating efficiency of the entire mining system. The entire mining system includes a mining vehicle, an ore processing system for the mining vehicle, a lifting system, and subsequent process flows. The subsequent process flows include dehydration, transfer to a cargo hold, and transfer from the cargo hold to other ships. Small-sized ore is easily lost in the subsequent process flows.

[0061] The first screening structure 2 is used to screen out the ore in the collected ore fluid that exceeds the capacity of the lifting system and then crush it to avoid excessive crushing of the ore. The ore is then collected again into the conveying pipeline 4 through the power pipeline 7 and conveyed to the silo 6. At the entrance of the silo 6, the second screening structure 5 is used to screen out the ore and sediment that are too small, and the ore within a certain size range is retained. This achieves the goal of controlling the ore size to meet the requirements of the lifting system while reducing the content of small-sized ore and sediment, thereby improving the operating efficiency of the entire mining system.

[0062] Further, if Figure 1 , Figure 3-Figure 4As shown, the first screening structure 2 includes a first screening chamber, on which a first inlet 21, a first outlet 23 and a first branch port 22 are arranged. The first inlet 21 and the first outlet 23 are arranged opposite to each other and the flow direction of the fluid is consistent with the flow direction of the fluid in the conveying pipeline 4. The first branch port 22 faces downward and is connected to the crushing pipeline 8. A first filter 24 is installed at the first outlet 23, and the filtering accuracy of the first filter 24 is adapted to the upper limit of the target size. Figure 3 , Figure 4 In order to show the internal structure, the top closed structure is omitted.

[0063] Specifically, the number of first inlets 21 is consistent with the number of collection devices 1, and the first inlet 21 is connected to the outlet of the collection pump 13 of the collection device 1; the width of the first screening chamber matches the number of collection devices 1; the first branch port 22 is connected to the inlet of the branch pipe section 81, and in order to facilitate the entry of ore into the branch pipe section 81, the first branch port 22 is funnel-shaped; the first filter 24 throttles the ore in the ore fluid that is larger than the upper limit of the target size, and then enters the crushing pipeline 8 from the first branch port 22, and the fluid flowing out from the first outlet 23 behind the first filter 24 is the first small-size fluid.

[0064] Further, if Figure 3 , Figure 5 As shown, the first filter 24 is a perforated plate structure, and the lower edge of the first filter 24 is flush with the edge of the first branch port 22. The first filter 24 is provided with a plurality of circular first through holes 240, and the diameter of the first through holes 240 is consistent with the upper limit of the target size. The first filter 24 is detachably installed inside the channel of the first outlet 23, and the lower edge of the first filter 24 is flush with the edge of the first branch port 22, so that the oversized ore can slide into the first branch port 22.

[0065] Further, if Figure 1 , Figure 3-Figure 4 As shown, the power pipeline 7 includes a confluence pipe 71, a water pump 73 is installed at one end of the confluence pipe 71, the other end of the confluence pipe 71 is connected to the confluence port 3, and an ore inlet 72 is provided on the side wall of the confluence pipe 71. The ore inlet 72 is connected to the end of the crushing pipeline 8 for receiving crushed ore. The water pump 73 provides water flow into the confluence pipe 71 to mix with the crushed ore to form a second small-sized fluid, and transports the second small-sized fluid into the confluence port 3.

[0066] Specifically, the conduit 71 includes a horizontal section, and an ore inlet 72 is provided on the upper side wall of the horizontal section. The ore inlet 72 is connected to the lower end of the branch pipe section 81. A water pump 73 is installed at one end of the horizontal section. The water inlet of the water pump 73 is placed in seawater, and the water outlet of the water pump 73 is connected to one end of the horizontal section. The conduit 71 also includes a curved pipe section, which connects the other end of the horizontal section with the conduit 3. The curved pipe section can be a vertical pipe section or an inclined pipeline facing the direction of the fluid in the conveying pipeline 4.

[0067] The working principle of the power pipeline 7 is: the water pump 73 delivers seawater of a certain pressure and flow rate into the horizontal section. The seawater flows in the confluence pipe 71 and drives the ore from the crushing pipeline 8 to form a second small size fluid and is transported from the confluence port 3 to the transport pipeline 4.

[0068] The power pipeline 7 of this embodiment not only realizes the transportation of crushed ore by overcoming gravity, but also is used to enhance the situation of insufficient power inside the conveying pipeline 4 due to the resistance loss of the first screening structure 2, so that the ore fluid in the direction of the conveying pipeline 4 is continuously transported.

[0069] like Figure 3-Figure 4 As shown, the cross-section of the first screening chamber and the cross-section of the delivery pipeline 4 are consistent in size. In order to facilitate the connection between the manifold 71 and the delivery pipeline 4, the structure of the confluence port 3 is funnel-shaped.

[0070] Further, if Figure 1 , Figure 3-Figure 4 As shown, the second screening structure 5 includes a second screening chamber, on which a second inlet 51, a second outlet 53 and a second branch port 52 are arranged. The second inlet 51 and the second outlet 53 are arranged opposite to each other and the flow direction of the fluid is consistent with the flow direction of the fluid in the conveying pipeline 4. The second branch port 52 faces downward and is connected to the inlet of the silo 6. A second filter 54 is arranged at the second outlet 53, and the second filter 54 is adapted to the lower limit of the target size.

[0071] Specifically, the second inlet 51 is connected to the end of the conveying pipeline 4, and its size is consistent with the flow cross-section of the conveying pipeline 4; the second branch port 52 is directly connected to the silo body 63 of the silo 6; the second filter 54 throttles the ores larger than the target size lower limit in the pretreated small-size fluid and drops them into the inlet of the silo 6, and the fluid flowing out of the second outlet 53 behind the second filter 54 is particles smaller than the target size lower limit, including ores and sediment.

[0072] like Figure 5As shown, the second filter 54 is a perforated plate structure, and the lower edge of the second filter 54 is flush with the edge of the second branch port 52. The second filter 54 is provided with a plurality of circular second through holes 540, and the diameter of the second through holes 540 is consistent with the lower limit of the target size. The second filter 54 is detachably installed inside the channel of the second outlet 53, and the lower edge of the second filter 54 is flush with the edge of the second branch port 52, so that the ore can slide into the first branch port 22.

[0073] Further, if Figure 1 , Figure 3-Figure 4 As shown, the crushing pipeline 8 includes a branch pipe section 81, one end of which is connected to the first screening structure 2 for receiving ores larger than the upper limit of the target size, and the other end of the branch pipe section 81 is connected to the power pipeline 7. A crusher 82 is installed in the middle of the branch pipe section 81, and the crusher 82 is used to crush ores larger than the upper limit of the target size.

[0074] Specifically, the crusher 82 can be a single-tooth roller crusher, a double-tooth roller crusher, a jaw crusher or other types of crushers; the upper end of the branch pipe section 81 is connected to the first branch port 22, and the lower end of the branch pipe section 81 is connected to the ore inlet 72.

[0075] Further, if Figure 1 , Figure 3-Figure 4 As shown, the silo 6 includes a silo body 63 and a fluid power device 64 arranged on the upper part of the silo body 63. A discharge port 61 opposite to the fluid power device 64 is arranged on the upper part of the silo body 63. A third filter 62 is arranged on the discharge port 61. The fluid power device 64 is used to generate a water flow above the inside of the silo body 63 to discharge small particle size substances entering the silo body 63 from the discharge port 61.

[0076] Specifically, small-particle materials include mud and small-particle ore; a bottom compartment with an inclined surface is provided at the lower part of the silo 63 to facilitate the discharge of ore from the silo 63; the discharge port 61 is used to discharge water and mud, and the third filter 62 is sufficient to block the ore from entering the discharge port 61 and facilitate the passage of water carrying mud. The structure of the third filter 62 is similar to that of the first filter 24 and the second filter 54, and is used to discharge small-particle ore or mud out of the silo 6; the fluid power device 64 can be a water jet pump, which is used to form a water flow at the entrance of the silo 6 and above the inside of the silo 6 to assist the small-particle ore or mud to be discharged from the silo 6 through the third filter 62.

[0077] Embodiment 2:

[0078] The deep-sea mining vehicle ore processing method of this embodiment comprises the following steps:

[0079] Primary screening: screening out the ore fluid from the mine car collection device 1 to remove the ore larger than the upper limit of the target size to form a first small size fluid;

[0080] Crushing: crushing the ore that is larger than the upper limit of the target size;

[0081] Power-driven confluence: the crushed ore is mixed with the continuous water flow to form a second small-sized fluid, and the first small-sized fluid and the second small-sized fluid are mixed to form a pre-treated small-sized fluid and transported to the direction of the silo 6;

[0082] Secondary screening: the pre-treated small-size fluid is screened to separate the ores larger than the target size lower limit into the silo 6, and the particles smaller than the target size lower limit are discharged with the water flow.

[0083] Finally, the ore with a size range from the upper limit of the target size to the lower limit of the target size is obtained. Since the water flow entering the silo 6 from the entrance of the silo 6 is inevitably mixed with mud and small particles of ore, three screenings are set inside the silo 6 to remove the mud and small particles of ore in the water flow at the upper end of the silo 6.

[0084] Embodiment three:

[0085] The deep-sea mining vehicle ore processing method of this embodiment, using the deep-sea mining vehicle ore processing system of the first embodiment, comprises the following steps:

[0086] Primary screening: the ore fluid from the mining vehicle collection device 1 is screened out by the first screening structure 2 to form a first small-size fluid after ores larger than the upper limit of the target size are screened out. The first small-size fluid flows into the conveying pipeline 4;

[0087] Selective crushing: ores larger than the upper limit of the target size enter the crushing pipeline 8 from the first branch port 22 of the first screening structure 2 for crushing, and are crushed to a size below the upper limit of the target size;

[0088] Power-driven confluence: The crushed ore enters the power pipeline 7 and mixes with the continuous water flow to form a second small-sized fluid, and enters the conveying pipeline 4 from the confluence port 3. The first small-sized fluid and the second small-sized fluid are mixed to form a pre-treated small-sized fluid and are conveyed toward the silo 6;

[0089] Secondary screening: After pretreatment, the small-sized fluid passes through the second screening structure 5 to screen out the ore larger than the target size lower limit, that is, the ore with a size range from the target size upper limit to the target size lower limit is obtained, and the ore enters the silo 6 from the second branch port 52 of the second screening structure 5, and the particles smaller than the target size lower limit are discharged from the second outlet 53 along with the water flow.

[0090] Three screenings: The water flow entering the silo 6 together with the ore is inevitably mixed with silt and small particles of ore. The water flow is driven by the fluid power device 64, so that the water flow carries the silt and small particles of ore and is discharged from the discharge port 61 at the top of the silo 6. The ore larger than and smaller than the lower limit of the target size is intercepted and retained in the silo 6.

[0091] Through the mutual cooperation of the first screening structure 2, the second screening structure 5, the crushing pipeline 8, the power pipeline 7 and the conveying pipeline 4, the size of the ore entering the silo 6 is controlled within the set range, thereby avoiding the ore entering the lifting system being too large or too small, avoiding excessive crushing of ore of moderate size, and achieving the final desludging and desanding of the ore.

[0092] The above description is an explanation of the present invention, not a limitation of the present invention. The scope of the present invention is defined in the claims. Any form of modification may be made within the scope of protection of the present invention.
