Description

Technical Field

[0001] This application relates to the field of laterite nickel ore feeding technology, specifically to a novel laterite nickel ore feeding device. Background Technology

[0002] In the processing of laterite nickel ore, the raw material needs to be fed to the ore inlet, i.e., the inlet of the feed hopper. After feeding, the raw material undergoes a series of production process treatments. For example, Chinese Patent 202310601638.X discloses a laterite nickel ore suspension roasting pre-reduction-smelting system and process, including a feed hopper, screw feeder, dispersant, preheater, suspension furnace, gas-solid separation device, dust collector, reactor, electric furnace, air separation equipment, fan, and sulfur recovery system. Currently, the feeding method for nickel ore is mostly to use transport vehicles to pour the ore into the ore inlet of the production line.

[0003] The existing technology has the following drawbacks: Since there is only one ore inlet, transport vehicles need to unload the ore one by one, which will cause a large number of transport vehicles to queue at the ore inlet, affecting the efficiency of ore unloading. Summary of the Invention

[0004] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a new type of feeding equipment for laterite nickel ore, which solves the technical problem that a large number of transport vehicles need to queue at the ore inlet in the existing technology, affecting the efficiency of ore pouring.

[0005] To achieve the above-mentioned technical objectives, the present application adopts the following technical solution:

[0006] This application provides a novel feeding device for laterite nickel ore, comprising:

[0007] A rotating platform is provided with a partition on its top, which divides the top of the rotating platform into a first stacking pit and a second stacking pit. The rotating platform is used to rotate the first stacking pit and the second stacking pit to replace their positions.

[0008] A material pouring platform is located on both sides of the first stacking pit, and a stacking mechanism is provided on it for pushing materials on the pouring platform from both sides towards the first stacking pit in the middle; and

[0009] The grabbing mechanism is installed directly above the second stacking pit and is used to grab materials and deliver them to the ore inlet.

[0010] In some embodiments, the rotating platform includes a circular platform and a driving mechanism. The output end of the driving mechanism is connected to the circular platform to drive the circular platform to rotate. A recess is provided on the top of the circular platform, and the partition is disposed on the midpoint bisector of the recess.

[0011] In some embodiments, the pouring platform is strip-shaped with a nested opening, and the rotating platform is embedded in the nested opening and flush with the upper surface of the pouring platform.

[0012] In some embodiments, a vertical plate flush with the partition is provided on one side of the material pouring platform, and an arc-shaped baffle is provided on the other side of the material pouring platform.

[0013] In some embodiments, the material pouring platform is provided with a fence surrounding the second stacking pit on one side corresponding to the gripping mechanism.

[0014] In some embodiments, there are two stacking mechanisms, which are respectively disposed on both sides of the rotating platform. Each stacking mechanism includes a linear drive and a pusher plate. The linear drive is mounted on the upright plate, and the pusher plate is connected to the movable end of the linear drive. The linear drive is used to drive the pusher plate to move along the length direction of the unloading platform.

[0015] In some embodiments, the linear drive includes a drive motor, a guide rail, a lever, and a slider. The guide rail is fixed to the top of the vertical plate, the lever is rotatably connected to the inner side of the guide rail, the slider is threaded to the outer side of the lever and limits its sliding on the inner side of the guide rail, the slider is connected to the push plate through a bracket, the drive motor is mounted at one end of the guide rail, and its conveying shaft is connected to the lever.

[0016] In some embodiments, the push plate is arc-shaped, and the radius of the arc of the push plate matches the radius of the circular platform.

[0017] In some embodiments, the gripping mechanism includes a gantry crane, which has a lifting member, a traversing member, and a gripping member. The traversing member is disposed at the bottom of the gantry crane, the lifting member is disposed at the top of the gantry crane, and the gripping member is disposed at the movable end of the lifting member.

[0018] In some embodiments, the gripping member includes a pair of hoppers and a pair of hydraulic push rods. The hoppers are hinged to the movable end of the lifting member. One end of each hydraulic push rod is hinged to the corresponding hopper, and the other end is hinged to the movable end of the lifting member, for extending and retracting to drive the two hoppers to open and close.

[0019] Compared with the prior art, the novel feeding equipment for laterite nickel ore provided in this application allows multiple transport vehicles to dump materials side by side through a dumping platform. The material is then concentrated and piled into a central storage pit by a stacking mechanism.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0031] To address the technical problem of a large number of transport vehicles queuing at the ore inlet, which affects the efficiency of ore dumping, this application provides a novel feeding device for laterite nickel ore, which enables multiple transport vehicles to dump ore simultaneously and to centrally stockpile the ore.

[0032] It should be noted that the novel feeding equipment for laterite nickel ore described in this application is used for, but not limited to, feeding laterite nickel ore. For ease of explanation, this application will only use the application of the novel feeding equipment for laterite nickel ore as an example for illustration. The principle of the novel feeding equipment for laterite nickel ore in feeding other types of minerals is essentially the same as that in feeding laterite nickel ore, and will not be elaborated here.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a novel feeding device for laterite nickel ore in one embodiment of this application. The novel feeding device for laterite nickel ore includes a rotating platform 1, a pouring platform 2, and a gripping mechanism 3. A partition 101 is provided on the top of the rotating platform 1, dividing the top of the rotating platform 1 into a first stacking pit 102 and a second stacking pit 103. The rotating platform 1 is used to rotate the first stacking pit 102 and the second stacking pit 103 to exchange their positions. The first stacking pit 102 is on the same side as the dumping platform 2. During the rotation, the first stacking pit 102 and the second stacking pit 103 can be exchanged in position. The dumping platform 2 is located on both sides of the first stacking pit 102, extending the dumping position to both sides, so that multiple transport vehicles can dump materials side by side onto the dumping platform 2. The dumping platform 2 is provided with a stacking mechanism 4, which is used to push the material on the dumping platform 2 from both sides towards the first stacking pit 102 in the middle. After the transport vehicles dump the material onto the dumping platform 2, the stacking mechanism 4 pushes the material from both sides towards the middle. The material is pushed and concentrated in the first stacking pit 102 on this side. The dumping platform 2 and the rotating platform 1 are only in contact on both sides, without affecting the rotation of the rotating platform 1. The rotating platform 1 itself can still rotate. The grabbing mechanism 3 is set up directly above the second stacking pit 103 to grab the material and put it into the ore inlet. The rotating platform 1 replaces the stacking pit 102 with the second stacking pit 103. The first stacking pit 102 with the material is rotated to be directly below the grabbing mechanism 3. The grabbing mechanism 3 lifts and grabs the material, and then moves it horizontally to the ore inlet for feeding. The second stacking pit 103, which has been replaced, is empty and can continue to be used for the next batch of material feeding from the transport vehicles. This can effectively improve the efficiency of ore pouring, avoid serious queuing of transport vehicles, and improve the overall work efficiency.

[0034] In one embodiment, please refer to Figure 1The rotating platform 1 includes a circular platform 11 and a driving mechanism. The driving mechanism is not shown in the figures. The output end of the driving mechanism is connected to the circular platform 11 and is used to drive the circular platform 11 to rotate. A recess is provided on the top of the circular platform 11. The partition 101 is arranged on the middle bisector of the recess. The recess has an arc surface that transitions from the periphery to the center, which is used to guide the ore to gather in the center, so as to facilitate the gripping of the subsequent mechanism 3.

[0035] Understandably, the drive mechanism can use a high-torque motor to drive the circular platform 11 to rotate, or it can use a hydraulic cylinder push rod to reciprocate by rotating 180°, so as to achieve a 180° rotation between the two stacking pits and replace their positions.

[0036] In one embodiment, please refer to Figure 2 The material unloading platform 2 is strip-shaped, allowing multiple transport vehicles to unload materials side by side. A semi-circular nested opening 201 is provided in the middle of the material unloading platform 2. Half of the rotating platform 1 is embedded in the nested opening 201 and is flush with the upper surface of the material unloading platform 2. By pushing the material on the material unloading platform 2, it can be pushed into the first stacking pit 102 on the middle rotating platform 1 for centralized stacking.

[0037] Furthermore, in order to prevent ore from overflowing during the process of ore concentration, a vertical plate 202 flush with the partition 101 is provided on one side of the dumping platform 2 to prevent ore from overflowing from that side, and an arc-shaped baffle 203 is provided on the other side of the dumping platform 2 to prevent ore from overflowing from the other side.

[0038] Furthermore, in order to prevent the stockpiled ore from overflowing after the replacement position, a barrier 204 is provided on the other side of the dumping platform 2 to surround the second stockpiling pit 103 on that side, thereby preventing the ore from overflowing after the replacement.

[0039] Furthermore, in order to push the ore to form a pile, there are two stacking mechanisms 4, which are respectively arranged on both sides of the rotating platform 1. Each stacking mechanism 4 includes a linear drive 41 and a pusher plate 42. The linear drive 41 is mounted on the vertical plate 202, and the pusher plate 42 is connected to the movable end of the linear drive 41. The linear drive 41 is used to drive the pusher plate 42 to move along the length direction of the pouring platform 2. The two pushers 42 move towards the middle at the same time, so that the ore on both sides can be pushed into the first stacking pit 102 in the middle.

[0040] Please refer to the following for usage: Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The transport vehicle dumps material onto the dumping platform 2. The linear drive component 41 drives the push plate 42 to move towards the center, pushing the ore from the dumping platform into the first stacking pit 102. Then, the rotating platform 1 rotates 180° to replace the positions of the first stacking pit 102 and the second stacking pit 103. The push plate 42 is then reset to allow for the next round of material dumping.

[0041] For details, please refer to Figure 1 The linear drive component 41 includes a drive motor 411, a guide rail 412, a lever 413, and a slider 414. The guide rail 412 is fixed to the top of the vertical plate 202. The lever 413 is rotatably connected to the inner side of the guide rail 412. The slider 414 is threaded to the outer side of the lever 413 and is limited to slide on the inner side of the guide rail 412. The slider 414 is connected to the push plate 42 through a bracket. The drive motor 411 is installed at one end of the guide rail 412, and its conveying shaft is connected to the lever 413. The drive motor 411 drives the lever 413 to rotate. Under the limited guidance of the guide rail 412, the slider 414 moves linearly, thereby driving the corresponding push plate 42 to move.

[0042] Optionally, the pusher plate 42 is arc-shaped, and the radius of the arc of the pusher plate 42 matches the radius of the circular platform 11, so that all the ore can be pushed into the stacking pit, reducing the residue on the dumping platform 2.

[0043] In one embodiment, please refer to Figure 1 In order to grab the ore, the grabbing mechanism 3 includes a gantry crane 31. The gantry crane 31 has a lifting component 32, a traversing component 33, and a grabbing component 34. The traversing component 33 is located at the bottom of the gantry crane 31, the lifting component 32 is located at the top of the gantry crane 31, and the grabbing component 34 is located on the movable end of the lifting component 32. The grabbing component 34 is lowered by the lifting component 32 to grab the ore, then lifted, and then moved to the ore inlet by the traversing component 33. The grabbing component 34 then feeds the ore, and the above actions are repeated.

[0044] Understandably, both the lifting component 32 and the lateral movement component 33 can be linear drive mechanisms driven by linear guide rails, which are existing mature mechanical structures that can achieve the purpose of lifting and lateral movement. The lifting component 32 can also be an electric hoist or a winch.

[0045] Furthermore, the gripping component 34 includes a pair of hoppers 341 and a pair of hydraulic push rods 342. The hoppers 341 are hinged to the movable end of the lifting component 32. One end of the hydraulic push rod 342 is hinged to the corresponding hopper 341, and the other end is hinged to the movable end of the lifting component 32. It is used to telescopically drive the two hoppers 341 to open and close. By telescopically extending and retracting the hydraulic push rods 342, the two hoppers 341 can be driven to open and close, thereby gripping and discharging the ore.

[0046] To better understand this application, the following is combined with... Figures 1 to 5 The technical solution of this application is described in detail as follows: The transport vehicles are arranged in rows on one side of the unloading platform 2 to unload the ore. After unloading, the push plate 42 is driven by the linear drive component 41 to move towards the middle, pushing the ore to the first stacking pit 102 for stacking. After stacking, the rotating platform 1 is rotated to exchange the two stacking pits, so that the empty second stacking pit 103 is moved to one side of the unloading platform 2, and the transport vehicles unload the ore again. The first stacking pit 102, which is rotated to the other side and has ore piled up, is then grabbed by the grabbing mechanism 3 and put into the ore inlet or silo.

[0047] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
