[0031] As Figure 1 And Figure 2As shown, the application provides a horizontal-vertical taking ore blending system for blending slurry-like laterite nickel ore, which comprises a storage bin 1, a feeding device 2, an ore separation device 3 and a taking device 4. The storage bin 1 has a storage space for storing ore. The top of the storage bin 1 has an opening for communication between the inside and outside. The discharge port of the feeding device 2 is in communication with the storage space for introducing ore into the storage space. The ore separation device 3 comprises a separation piece 31 and a separation piece lifting assembly 32. The separation piece lifting assembly 32 is arranged on the storage bin 1, and the separation piece 31 is arranged at the output end of the separation piece lifting assembly 32. The separation piece lifting assembly 32 can drive the separation piece 31 to lift in the storage space to separate the ore in the storage space into several portions distributed circumferentially. The taking device 4 can grab the ore separated by the separation piece 31 one by one through the opening.

[0032] Different ore points and batches of ore are introduced into the storage space of the storage bin 1 by the feeding device 2 to form multiple layers of ore in the storage bin 1. Then, the separation piece 31 lifts to separate the multiple layers of ore into several portions. Each portion of ore includes ore of different ore points and batches. The taking device 4 grabs each portion of separated ore one by one to complete blending. The difference between each portion of blended ore is small, which can make the process parameters and equipment settings in the subsequent processing process unnecessary to be adjusted, thereby improving production efficiency. The above system has a simple structure, does not require a large site and complex equipment, and has a low cost.

[0033] In the current embodiment, the storage bin 1 is in a cylindrical shape, and the inside thereof forms a cylindrical storage space.

[0034] In the current embodiment, the feeding device 2 comprises a feeding hopper and a screw feeder 21. The screw feeder 21 is arranged obliquely, and the lower end thereof is in communication with the storage space, and the higher end thereof is in communication with the bottom of the feeding hopper. The ore is first poured into the feeding hopper and then introduced into the storage bin 1 through the screw feeder 21. Since the laterite nickel ore is generally in a slurry state, different ore points and batches of ore form a layer of ore in the storage space.

[0035] In the current embodiment, the screw feeder 21 comprises a feeding pipe, a spiral plate and a driver. The feeding pipe is arranged obliquely, and the higher end thereof is provided with a feeding port in communication with the bottom of the feeding hopper. The lower end of the feeding pipe is in communication with the storage space of the storage bin 1. The spiral plate is coaxially arranged in the feeding pipe, and the driver is fixed on the higher end of the feeding pipe and fixed with the spiral plate. The driver drives the spiral plate to rotate and pushes the ore in the feeding pipe to move into the storage bin 1. The screw feeder 21 is a prior art, and its more specific structure will not be described here.

[0036] Understandably, the storage bin 1 has an inlet hole 11 on its side wall, and the lower end of the screw feeder 21 is connected to the inlet hole 11, so that the ore is introduced into the storage bin 1 through the inlet hole 11.

[0037] like Figure 2 As shown, in some embodiments, the separator 31 includes multiple partitions 311, which are combined and spliced ​​to form several compartments with identical spaces, ensuring that each compartment contains the same amount of ore. In the current embodiment, the separator 31 has a central column, and the multiple partitions 311 are distributed circumferentially along the central column. One end of each partition 311 is connected to the central column, and the other end extends outward from the central column, forming fan-shaped compartments of the same size between adjacent partitions 311. In other embodiments, the multiple partitions 311 can be spliced ​​to divide the space into multiple compartments of other identical shapes.

[0038] like Figure 2 As shown, specifically, the separator lifting assembly 32 includes a sliding rail 321, a slider 322, and a lifting drive (not shown in the figure). The sliding rail 321 is fixed vertically to the inner wall of the storage bin 1. The slider 322 is slidably connected to the sliding rail 321. In this embodiment, the lifting drive is located outside the storage bin 1. The output end of the lifting drive is sealed through the bin wall of the storage bin 1 and connected to the slider 322. Thus, the slider 322 can move along the sliding rail 321 and stop at any position within its stroke, driven by the lifting drive. In this embodiment, the lifting drive includes, but is not limited to, a lead screw motor. The slider 322 is fixedly connected to the end of the partition 311 away from the central column, thereby ensuring stability during separation. When the slider 322 moves along the sliding rail 321, it drives the partition 311 to rise and fall vertically. When the slider 322 rises vertically to its highest position, the separator 31 completely disengages from the ore. When the slider 322 descends vertically to its lowest position, the separator 31 abuts against the bottom surface of the storage silo 1. After the ore has been introduced, the slider 322 descends vertically to its lowest position, and the separator 31 abuts against the bottom surface of the storage silo 1, thus separating the ore. For example, multiple sliding tracks 321 are spaced circumferentially along the inner wall of the storage silo 1.

[0039] like Figure 1 As shown, in some embodiments, the material handling device 4 includes a mobile gantry crane 41, a lifting member 42, a lateral moving member 43, and a gripping member 44. The mobile gantry crane 41 spans across the storage silo 1 and extends to the subsequent processing step. The lateral moving member 43 is fixed on the mobile gantry crane 41 and has a moving end that is fixedly connected to the lifting member 42, driving the lifting member 42 to move horizontally. The lifting member 42 has a lifting end that is fixedly connected to the gripping member 44, driving the gripping member 44 to move vertically. The gripping member 44 is used to grip the ore.

[0040] It should be noted that the moving direction of the mobile gantry crane 41 is perpendicular to the moving direction of the transverse moving member 43, so that the lifting member 42 can move in the entire horizontal plane and can correspond to any separated ore material.

[0041] Specifically, the mobile gantry crane 41 comprises 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 procedure. The mover 412 is arranged on the gantry track 411 and can move along the gantry track 411. The gantry frame 413 is fixedly connected with the mover 412. When the mover 412 moves along the gantry track 411 to the next processing procedure, the gantry frame 413 moves from above the storage bin 1 to above the next processing procedure. It can be understood that the mobile gantry crane 41 is also a commonly used device in the prior art, and the specific structure will not be described again.

[0042] Further, the grabbing member 44 comprises a pair of grab buckets 441 and a pair of hydraulic push rods 442. The grab buckets 441 are hingedly connected with the movable end of the lifting member 42. One end of the hydraulic push rod 442 is hingedly connected with the corresponding grab bucket 441, and the other end is hingedly connected with the movable end of the lifting member 42. The hydraulic push rod 442 is used to drive the two grab buckets 441 to open and close. Through the extension and retraction of the hydraulic push rod 442, the two grab buckets 441 can be driven to open and close, so as to grab and release the ore material. In addition, the lifting member 42 can be but is not limited to a lifting appliance or a hydraulic cylinder, and the transverse moving member 43 can be but is not limited to a transverse moving linear driving module.

[0043] When the ore is fed, the ore is first poured into the feeding hopper, and then introduced into the storage bin 1 through the screw feeder 21. Since the laterite nickel ore is generally in the form of slurry, the ore poured at the same time will form a layer of ore in the storage bin 1, and the ore poured at different times will form stratification in the storage bin 1. When a plurality of batches of ore are stored in the storage bin 1, the lifting driving member drives the slider 322 to descend to the lowest position in the vertical direction, the partition piece 31 abuts against the bottom surface of the storage bin 1, the ore is separated, and the ore is separated into a plurality of portions in the vertical direction (each portion of ore contains a plurality of batches of ore), and the ore in each portion is approximately the same as that in each other portion. The mover 412 moves along the gantry rail 411, so that the gantry 413 is located above the storage bin 1. The traversing piece 43 drives the lifting piece 42 to move, and corresponds to a portion of ore to be grabbed. The lifting piece 42 drives the grabbing piece 44 to descend, the hydraulic push rod 442 pushes the grab bucket 441 to open and then close, and the ore is grabbed. Subsequently, the lifting piece 42 drives the grabbing piece 44 to ascend, the mover 412 moves along the gantry rail 411, so that the gantry 413 moves above the next process, and the hydraulic push rod 442 pushes the grab bucket 441 to open, so that the grabbed ore falls into the next process. In this way, the ore in the entire storage bin 1 can be sent to the next process. Thus, the feeding device 2 introduces the ore from different ore points and different batches into the storage bin 1, and forms a plurality of layers of ore in the storage bin 1. The ore separating device 3 separates the plurality of layers of ore into a plurality of portions in the vertical direction, each portion of ore includes ore from different ore points and different batches, and the taking device 4 grabs each portion of ore one by one. The difference between each portion of ore is small, so that the process parameters and equipment settings in the subsequent processing process do not need to be adjusted, the production efficiency is improved, the ore blending system has a simple structure, does not need a large site and complex equipment, and has a low cost.

[0044] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled persons in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the utility model. Here, all the embodiments need not and cannot be exhausted. Any modification, equivalent substitution and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
