Description

Technical Field

[0001] The present application relates to the technical field of laterite nickel ore blending, and in particular to a flat-laying vertically adjusted ore blending system. Background Art

[0002] Laterite nickel ore is a loose, clay-like, multi-mineral aggregate formed by long-term weathering, leaching, dissemination, and alteration of nickel-bearing olivine bedrock in tropical or subtropical regions. It contains metallic components such as nickel, cobalt, chromium, magnesium, and aluminum. Laterite nickel ore resources account for approximately 55% of global nickel resources and are primarily distributed in tropical and subtropical countries and regions within 22° north and south latitude. Laterite nickel ore resources are relatively concentrated, and large deposits and mining areas are often formed within these mineralization belts. Examples include the New Caledonia laterite nickel mining area in the French South Pacific, the Mologas and Sulawesi laterite nickel mining areas in Indonesia, the Queensland laterite nickel mining area in Australia, and the Palawan laterite nickel mining area in the Philippines. However, nickel ore mineralization is complex, making it a difficult-to-process oxidized ore resource. Furthermore, long-term post-mineralization weathering, leaching, dissemination, and alteration have resulted in a complex and variable mineral composition, prone to forming complex structures such as isomorphism. This composition fluctuates significantly across mining locations and depths. There are large differences between the mineral materials of different mining sites, and even differences between different batches of mineral materials at the same mining site. This will cause the process parameters and equipment settings to need to be repeatedly adjusted according to the mineral material conditions during subsequent processing, affecting production efficiency.

[0003] Patent CN216192589U discloses a device for blending laterite nickel ore, comprising a silo, a feeder, a belt conveyor, a ring-type distributor, and a hydraulic hammer. The discharge port at the bottom of the silo is connected to the feeder's inlet, which is in turn connected to the inlet of the belt conveyor, which in turn is connected to the ring-type distributor. The hydraulic hammer is aligned with the discharge port at the top of the silo. The device calculates the feed ratio for each silo to achieve ore blending.

[0004] However, the above-mentioned prior art requires multiple silos to store materials from different mining sites and different batches, and requires multiple material conveyor belts to transport materials, which places high demands on site space and equipment. Summary of the Invention

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0021] In order to solve the technical problem in the existing technology that has high requirements for site space and equipment, the present application provides a flat-laying vertical ore blending system, which realizes ore blending by layering ore and vertically taking materials, does not require a large site and complex equipment, and has low cost.

[0022] See also Figure 1 、 2 , Figure 1 This is a structural diagram of a flat vertical ore distribution system in one embodiment of the present application. Figure 2 yes Figure 1 Schematic top view of the intermediate storage silo.

[0023] The present application provides a flat-laying vertical ore distribution system, comprising: a storage bin 1, a feeding device 2, a mineral separation device 3 and a vertical material taking device 4, wherein a storage space for storing minerals is formed in the storage bin 1, and the discharge port of the feeding device 2 is connected to the storage space for introducing minerals into the storage space; the mineral separation device 3 comprises a partition 31 and a partition lifting structure 32, the partition lifting structure 32 is fixed on the inner wall of the storage bin 1, the partition 31 is connected to the partition lifting structure 32, the partition lifting structure 32 is used to drive the partition 31 to rise and fall, and separate the minerals in the storage space into several portions along the vertical direction, and the vertical material taking device 4 is used to grab each portion of minerals one by one.

[0024] In the present application, the feeding device 2 introduces mineral materials from different mining points and different batches into the storage bin 1 respectively, forming multiple layers of mineral materials in the storage bin 1; the mineral material separation device 3 separates the multiple layers of mineral materials into several portions in the vertical direction, and each portion of mineral materials includes mineral materials from different mining points and different batches. The vertical material taking device 4 grabs each portion of mineral materials one by one, and the difference between each portion of mineral materials is small, which can make it possible to avoid adjusting the process parameters and equipment settings in the subsequent processing process, thereby improving production efficiency. The structure of the ore distribution system is simple, does not require a large site and complex equipment, and has low cost.

[0025] In this embodiment, the storage bin 1 is cylindrical, with an opening at the top and a cylindrical storage space formed inside.

[0026] In this embodiment, the feeding device 2 includes a feeding hopper and a screw feeder 21. The screw feeder 21 is tilted, with its lower end connected to the storage space and its upper end connected to the bottom of the feeding hopper. Ore is first poured into the feeding hopper and then introduced into the storage bin 1 via the screw feeder 21. Because laterite nickel ore is generally slurry, ore from different mining sites and batches forms a layer within the storage space.

[0027] In this embodiment, the screw feeder 21 includes a feeding pipe, a spiral plate and a driver. The feeding pipe is arranged at an angle. The higher end of the feeding pipe is provided with a feeding port connected to the bottom of the feeding hopper. The lower end of the feeding pipe is connected to the storage bin 1. The spiral plate is coaxially arranged in the feeding pipe. The driver is fixed on the higher end of the feeding pipe and fixed to the spiral plate; the driver drives the spiral plate to rotate, pushing the mineral material in the feeding pipe to move toward the storage bin 1.

[0028] In this embodiment, a feed hole 11 is provided on the side wall of the storage bin 1, and a lower end of the screw feeder 21 is connected to the feed hole 11. Minerals are introduced into the storage bin 1 through the feed hole 11.

[0029] In this embodiment, the partition 31 includes a plurality of partitions 311 , and the plurality of partitions 311 are combined and spliced ​​to form a plurality of compartments with the same space, so as to ensure that the mineral materials contained in each compartment are the same.

[0030] In this embodiment, the partitions 311 are fixed in the vertical direction and arranged along the axis of the storage bin 1 , and fan-shaped areas of the same size are formed between adjacent partitions 311 .

[0031] In this embodiment, the separator lifting structure 32 includes a sliding track 321 and a slider 322. The sliding track 321 is vertically fixed to the inner wall of the storage bin 1. The slider 322 is slidably connected to the sliding track 321. The slider 322 can move along the sliding track 321 and stop at any position within its travel. The slider 322 is fixedly connected to the top of the partition 311. When the slider 322 moves along the sliding track 321, it drives the partition 311 up and down vertically. When the slider 322 rises to its highest vertical position, the separator 31 is completely out of contact with the material. When the slider 322 descends to its lowest vertical position, the separator 31 abuts the bottom surface of the storage bin 1. After the material is completely introduced, the slider 322 descends to its lowest vertical position, and the separator 31 abuts the bottom surface of the storage bin 1, separating the material.

[0032] In this embodiment, the vertical material handling device 4 includes a mobile gantry crane 41, a lifting member 42, a transverse member 43 and a grabbing member 44. The mobile gantry crane 41 is arranged across the storage bin 1 and extends to the subsequent processing process. The transverse member 43 is fixed on the gantry crane 41, has a moving end and is fixedly connected to the lifting member 42, driving the lifting member 42 to move in the horizontal direction. The lifting member 42 has a lifting end and is fixedly connected to the grabbing member 44, driving the grabbing member 44 to rise and fall in the vertical direction. The grabbing member 44 is used to grab mineral materials.

[0033] It should be noted that the moving direction of the mobile gantry crane 41 is perpendicular to the moving direction of the transverse member 43, so that the lifting member 42 can move in the entire horizontal plane and can correspond to any portion of mineral material.

[0034] In this embodiment, the mobile gantry crane 41 includes a gantry track 411, a mover 412, and a gantry frame 413. The gantry track 411 is laid on both sides of the storage bin 1 and extends to the next processing step. The mover 412 is installed on the gantry track 411 and can move along the gantry track 411. The gantry frame 413 is fixedly connected to the mover 412. When the mover 412 moves along the gantry track 411 to the next processing step, the gantry frame 413 moves from above the storage bin 1 to above the next processing step.

[0035] It can be understood that the lifting member 42 and the transverse member 43 can both adopt linear drive mechanisms driven by linear guide rails, which are existing mature mechanical structures and can achieve the purpose of lifting and transverse movement. The lifting member 42 can also adopt an electric hoist or winch.

[0036] Furthermore, the grabbing member 44 includes a pair of grab buckets 441 and a pair of hydraulic push rods 442. The grab buckets 441 are hinged to the movable end of the lifting member 42. One end of the hydraulic push rod 442 is hinged to the corresponding grab bucket 441, and the other end is hinged to the movable end of the lifting member 42, which is used to drive the two grab buckets 441 to open and close. By extending and retracting the hydraulic push rod 442, the two grab buckets 441 can be driven to open and close, thereby grabbing and releasing the mineral materials.

[0037] In order to better understand the present application, the technical solution of the present application is described in detail below with reference to the accompanying drawings: When incoming materials are introduced, the ore is first poured into the feeding hopper, and then introduced into the storage bin 1 through the screw feeder 21. Since laterite nickel ore is generally in the form of mud, the ore poured in at the same time will form a layer of ore in the storage bin 1, and the ore poured in at different times will form layers in the storage bin 1. When multiple batches of ore are stored in the storage bin 1, the slider 322 descends to the lowest position in the vertical direction, and the partition 31 abuts against the bottom surface of the storage bin 1 to separate the ore, and the ore is divided into several portions in the vertical direction (each portion of ore contains several batches of ore), and the ore conditions of each portion are roughly the same. The mover 412 moves along the gantry track 411, positioning the gantry 413 above the storage bin 1. The transverse member 43 drives the lifting member 42 to move, corresponding to a portion of the ore to be grabbed. The lifting member 42 drives the grabbing member 44 downward, and the hydraulic push rod 442 opens and closes the grabbing bucket 441 to grab the ore. The lifting member 42 drives the grabbing member 44 upward, and the mover 412 moves along the gantry track 411, positioning the gantry 413 above the next process. The hydraulic push rod 442 opens the grabbing bucket 441, allowing the grabbed ore to fall into the next process. This process can be repeated in this manner, allowing the entire ore in the storage bin 1 to be delivered to the next process.

[0038] The beneficial effects of the present application are as follows: the feeding device introduces the mineral materials from different mining points and different batches into the storage bin respectively, forming multiple layers of mineral materials in the storage bin; the mineral material separation device separates the multiple layers of mineral materials into several portions in the vertical direction, each portion of mineral materials includes mineral materials from different mining points and different batches, and the vertical material taking device grabs each portion of mineral materials one by one. The difference between each portion of mineral materials is small, which can make it unnecessary to adjust the process parameters and equipment settings in the subsequent processing process, thereby improving production efficiency. The structure of the ore distribution system is simple, does not require a large site and complex equipment, and has low cost.

[0039] The specific implementation methods of the present application described above do not limit the scope of protection of the present application. Any other corresponding changes and modifications made based on the technical concept of the present application should be included in the scope of protection of the claims of the present application.
