[0044] Because laterite nickel ore contains impurities such as woody and herbaceous substances, these impurities form scum in the slurry during the washing process. If not treated, they will affect the normal operation of equipment in subsequent processes. Therefore, this application improves the washing system to remove scum from the slurry.

[0045] like Figure 1 and Figure 2 As shown, this embodiment provides a ore washing system. Specifically, it includes an ore washing machine 100, a screening mechanism 200, and a second collection component 300.

[0046] The ore washing machine 100 has a slurry outlet 101. The screening mechanism 200 includes a movable screen 210, a drive assembly, and a first collector 220. The receiving surface of the movable screen 210 is used to receive the material coming into the slurry outlet 101. The first collector 220 is located on the side of the movable screen 210 away from the receiving surface. The drive assembly is connected to the movable screen 210 for driving the movable screen 210 to move. The movable screen 210 can drive the material on its receiving surface to move from its feed end to its discharge end. The second collector 300 is used to collect the material coming into the discharge end of the movable screen 210.

[0047] During operation of the ore washing system, the ore washing machine 100 washes the ore containing slag, and the resulting slurry mixed with slag is discharged from the slurry outlet 101. The slurry falls onto the receiving surface of the movable screen 210. The drive assembly drives the movable screen 210 to move in a set manner, such as vibrating, rotating, or shaking. Under the screening action of the movable screen 210, larger slag particles are retained above the movable screen 210 and gradually move towards the second collector 300 under the action of the movable screen 210, eventually falling onto the second collector 300. Smaller slurry particles pass through the mesh of the movable screen 210 and are collected by the first collector 220.

[0048] The ore washing system provided in this embodiment has a first collecting element 220 located on the side of the movable screen 210 away from the receiving surface, effectively collecting the slurry after screening. A second collecting element 300 collects the scum from the discharge end of the movable screen 210, achieving separate collection of scum and slurry. A driving component drives the movable screen 210 to continuously screen and transport the slurry mixed with scum, improving the overall efficiency of the ore washing system and facilitating continuous production.

[0049] like Figure 3 and Figure 4As shown, in some embodiments, the screening mechanism 200 further includes a vibrating frame 402, a driving component including a vibration drive 403, and a movable screen 210 including a plate-shaped screen 401. The vibration drive 403 is connected to the vibrating frame 402. The plate-shaped screen 401 is disposed on the vibrating frame 402 with its receiving surface facing upwards. The feed end of the plate-shaped screen 401 is located below the slurry outlet 101, and the plate-shaped screen 401 is inclined downwards from its feed end to its discharge end. The vibration drive 403 drives the vibrating frame 402 to vibrate, thereby causing the plate-shaped screen 401 to vibrate. This more effectively promotes the rapid movement and screening of the slurry mixed with scum on the plate-shaped screen 401, improving screening efficiency. The inclined arrangement of the plate-shaped screen 401 helps the scum move smoothly towards the discharge end under its own gravity, avoiding the accumulation and blockage of scum on the plate-shaped screen 401. The combination of vibration and tilting enables more thorough separation of scum and slurry, improving the accuracy and quality of screening. The feed end of the plate screen 401 is located directly below the slurry outlet 101, allowing for more direct and stable reception of slurry from the slurry outlet 101 of the washing machine 100, reducing slurry splashing and loss.

[0050] like Figure 3 and Figure 4 As shown, in this embodiment, the first collecting component 220 includes a collecting hopper 221, which is located directly below the plate-shaped screen 401. The vertical projection of the plate-shaped screen 401 lies within the projection of the collecting hopper 221. The collecting hopper 221 is conical and tapers vertically downwards, with an outlet at its lower end. That is, the slurry passing through the plate-shaped screen 401 is collected into the collecting hopper 221 and guided to other processes from the outlet. The conical shape and vertical taper of the collecting hopper 221 help to concentrate the collected slurry and guide it to the outlet, facilitating subsequent processing and transportation, and preventing slurry accumulation and blockage during collection, thereby improving the efficiency of the entire collection process. The collecting hopper 221, located directly below the plate-shaped screen 401, can effectively collect the slurry falling from the screen, preventing slurry spillage and loss. In this embodiment, a plate-shaped screen 401 is disposed at the upper end of the vibrating frame 402, and the upper opening of the collecting hopper 221 is fixedly connected to the lower end of the vibrating frame 402. The vibration drive 403 in this embodiment can be a vibration motor, which can be disposed on the collecting hopper 221.

[0051] like Figure 4As shown, optionally, the vibrating frame 402 is vertically slidably mounted on the washing machine 100. The screening mechanism 200 also includes an elastic element 407, and the vibrating frame 402 is connected to the washing machine 100 via the elastic element 407. Vertical vibration helps the slurry fall vertically onto the first collecting element 220, thus ensuring effective collection. Driven by the vibration drive 403, and with the elastic force of the elastic element 407, the elastic element 407 can store and release energy, assisting the vibration drive 403 in maintaining a stable vibration state for the vibrating frame 402 and reducing energy consumption. Furthermore, the elastic element 407 reduces the impact force generated by the reciprocating motion of the vibrating frame 402, resulting in smoother and more regular movement, which helps improve the accuracy and effectiveness of screening.

[0052] like Figure 4 As shown, optionally, a guide rod 404 is fixed on the ore washing machine 100 (not shown in the figure). Limiting elements 405 are provided at both ends of the guide rod 404. A slider 406 is fixed on the vibrating frame 402. The slider 406 is slidably mounted on the guide rod 404 in the vertical direction. An elastic element 407 is sandwiched between the slider 406 and one of the limiting elements 405. The cooperation between the guide rod 404 and the slider 406 ensures that the vibrating frame 402 can slide precisely in the vertical direction, avoiding offset and shaking during vibration, thus ensuring the accuracy and stability of screening. The limiting elements 405 at both ends limit the movement range of the slider 406, preventing excessive movement of the vibrating frame 402 and causing equipment damage or malfunction, thus protecting the equipment. By sandwiching the elastic element 407 between the slider 406 and one of the limiting elements 405, the installation position of the elastic element 407 is ensured to be stable, allowing it to effectively buffer and assist vibration. In this embodiment, the elastic element 407 can be a spring, which is sleeved on the guide rod 404 to achieve reliable installation.

[0053] In this embodiment, the two limiting members 405 are limiting rods spaced vertically and fixed to the side wall of the washing machine 100. Multiple guide rods 404 extend in the vibration direction of the vibration frame 402, and their upper and lower ends are respectively connected to the two limiting rods. The number of sliders 406 is the same as that of the guide rods 404, and they are all fixed to the side wall of the vibration frame 402.

[0054] like Figure 5 and Figure 6As shown, in some embodiments, the movable screen 210 includes a cylindrical screen 501, the driving assembly includes a rotary drive, and the first collecting member 220 includes an outer cylinder 502. The cylindrical screen 501 is rotatably disposed inside the outer cylinder 502. The rotary drive is kinetically connected to the cylindrical screen 501. The cylindrical screen 501 is inclined downward from its feed end to its discharge end, and the slurry outlet 101 extends into the cylindrical screen 501. The slurry output from the slurry outlet 101 of the washing machine 100 is discharged into the cylindrical screen 501. The rotary drive drives the cylindrical screen 501 to rotate inside the outer cylinder 502. Slurry that conforms to the aperture of the cylindrical screen 501 passes through the cylindrical screen 501 and enters the outer cylinder 502 for collection. Unconforming scum moves along the cylindrical screen 501 towards its discharge end and is discharged from the discharge end of the cylindrical screen 501 to the second collecting member 300.

[0055] The rotating motion of the cylindrical screen 501 enables continuous screening, improving screening efficiency. Furthermore, the rotational motion ensures more uniform screening of materials within the cylindrical screen 501, enhancing screening quality. The cylindrical design saves space compared to a plate-shaped design, allowing for larger-area screening within a limited space, thus improving operational efficiency. The inclined design helps scum move smoothly towards the discharge end under the influence of rotation and gravity, preventing scum accumulation within the cylindrical screen 501.

[0056] like Figure 5 and Figure 6 As shown, optionally, the outer cylinder 502 includes a collecting hopper 221 located directly below the cylindrical screen 501. The vertical projection of the movable screen 210 lies within the projection of the collecting hopper 221. The collecting hopper 221 is conical and tapers vertically downwards. A first discharge port 505 is provided at the lower end of the collecting hopper 221. The collecting hopper 221 can effectively collect the slurry from the outer cylinder 502 and the cylindrical screen 501 after slag removal. The conical and tapering design facilitates the concentration and guidance of the collected slurry to the first discharge port 505, preventing the slurry from spilling out of other parts of the outer cylinder 502.

[0057] like Figure 5 and Figure 6 As shown, optionally, the screening mechanism 200 further includes an extension section 503, which is connected to the end of the outer cylinder 502 away from the slurry outlet 101. The extension section 503 has a second discharge port 506 located below the discharge end of the cylindrical screen 501. The extension section 503 can limit the splashing range of scum when it is discharged from the discharge end of the cylindrical screen 501, while the second discharge port 506 guides the scum to be discharged in its defined direction, thereby maintaining a clean working environment and reducing scum contamination. In this embodiment, the extension section 503 and the outer cylinder 502 are integrally connected, with a tight, gapless connection.

[0058] like Figure 6As shown, optionally, the rotary drive component includes a rotating shaft 507 and several drive wheels 508. The rotating shaft 507 is rotatably disposed between the outer cylinder 502 and the cylindrical screen 501, and is parallel to the cylindrical screen 501. The drive wheels 508 are disposed on the rotating shaft 507 and are in close contact with the cylindrical screen 501. The rotating shaft 507 drives the drive wheels 508 to rotate, thereby driving the cylindrical screen 501 to rotate, providing a stable rotary driving force to ensure the rotation of the cylindrical screen 501. This design allows the drive assembly to be compactly installed between the outer cylinder 502 and the cylindrical screen 501, saving overall space and making the structure of the entire screening mechanism 200 more compact. Furthermore, two rotating shafts 507 are respectively provided on both sides of the cylindrical screen 501 in the radial direction, and each rotating shaft 507 is provided with a drive wheel 508 to drive the cylindrical screen 501, thereby maintaining the smooth radial force on the cylindrical screen 501. In this embodiment, each rotating shaft 507 is provided with two drive wheels 508 spaced apart along the axial direction.

[0059] like Figure 6 As shown, in this embodiment, each rotating shaft 507 has two ends mounted on two bearing seats 509, which are mounted on the inner wall of the outer cylinder 502. The rotating shaft 507 can be driven by a motor or other rotary drive mechanism, which is not limited in this embodiment.

[0060] like Figure 6 As shown, optionally, at least two annular limiting portions 504 are provided on the outer peripheral wall of the cylindrical screen 501, and the two annular limiting portions 504 respectively stop on both sides of the drive wheel 508 in the axial direction. The two annular limiting portions 504 and the drive wheel 508 mutually limit each other in the axial direction, which can ensure that the drive wheel 508 always maintains good contact and transmission position with the cylindrical screen 501, and prevent the cylindrical screen 501 or the drive wheel 508 from shifting in the axial direction, thereby ensuring the stability and reliability of the transmission. In this embodiment, each drive wheel 508 is provided with annular limiting portions 504 on both sides in the axial direction, thereby improving the axial limiting effect.

[0061] In one embodiment, the drive wheel 508 is a concentric wheel, coaxial with the rotating shaft 507, thereby driving the cylindrical screen 501 to rotate stably. In another embodiment, the drive wheel 508 is an eccentric wheel, eccentric to the rotating shaft 507, thereby driving the cylindrical screen 501 to rotate while simultaneously causing the cylindrical screen 501 to sway radially.

[0062] like Figures 3-6As shown, this embodiment also includes a discharge assembly 600 for receiving the slurry exiting through the first collector 220. In one embodiment, the discharge assembly 600 includes a discharge pipe 601. However, due to the movement of the movable screen 210, the slurry cannot be effectively guided into the discharge pipe 601. Therefore, a transfer box 602 can also be provided, which is located at the bottom of the first collector 220, and the top of the discharge pipe 601 is connected to the transfer box 602, thereby solving the above problem.

[0063] like Figures 1-7 As shown, optionally, the second collecting element 300 is a conveyor belt 301, which is positioned below the discharge end of the movable screen 210. The ore is fed into the washing machine 100, where it is scrubbed. The scrubbed slurry flows from the slurry outlet 101 onto the movable screen 210, which screens the slurry, intercepting any scum and directing it onto the conveyor belt 301, which then transports it to a designated location. The conveyor belt 301 promptly transports the scum to the designated location, enabling continuous production and efficient operation.

[0064] like Figure 7 As shown, optionally, multiple washing machines 100 and screening mechanisms 200 are arranged in a one-to-one correspondence, with the multiple screening mechanisms 200 arranged sequentially along the length of the conveyor belt 301. A single conveyor belt 301 can process the slag output from multiple movable screens 210, effectively reducing labor costs.

[0065] like Figure 7 As shown, the second collecting component 300 may further include a collecting container 302, which is disposed at the discharge end of the conveyor belt 301 to receive scum.

[0066] like Figure 1 and Figure 2 As shown, optionally, the ore washing machine 100 includes a tank body 102 and two screw rods 103. A scrubbing trough 104 extending along its length is formed in the tank body 102. The scrubbing trough 104 is inclined upward along its length. The two screw rods 103 are rotatably disposed in the scrubbing trough 104 and are both parallel to the scrubbing trough 104. The rotation of the screw rods 103 can push solid media from bottom to top. A slurry outlet 101 is provided at the end of the tank body 102 opposite to the pushing direction of the screw rods 103.

[0067] When the ore washing machine 100 is operating, solid media such as ore are fed into the scrubbing tank 104 inside the pool 102. Since the scrubbing tank 104 is inclined upwards along its length and the screw rod 103 is parallel to the scrubbing tank 104, the screw rod 103 can push the solid media upwards when it rotates. During this pushing process, the ore, as a solid medium, rubs and collides with each other and contacts the screw rod 103 and the wall of the scrubbing tank 104, achieving a scrubbing effect and removing impurities and adhering substances. The thoroughly scrubbed material forms a slurry. Since the pool 102 has a slurry outlet 101 at the end opposite to the pushing direction of the screw rod 103, the slurry automatically flows out from the slurry outlet 101 under gravity and enters the screening mechanism 200.

[0068] The inclined scrubbing tank 104 works in conjunction with the rotating screw 103 to ensure that the ore is subjected to sufficient friction and scrubbing during the upward pushing process, effectively removing impurities and improving the cleanliness of the ore. The slurry outlet 101 is located at the end opposite to the pushing direction of the screw 103, and the slurry flows automatically to the slurry outlet 101 under the action of gravity.

[0069] like Figure 2 As shown, in this embodiment, the slurry outlet 101 is located at the top of the lower end of the scrubbing tank 104, and the slurry mixed with scum overflows from the slurry outlet 101. This embodiment does not limit the shape of the slurry outlet 101; the slurry outlet 101 can be frame-shaped or circular, etc.

[0070] like Figure 1 As shown, in some embodiments, in order to facilitate the introduction of the slurry to be scrubbed into the scrubbing tank 104, the ore washing system also includes a liquid supply component 105. The liquid supply component 105 extends to the upper position of the scrubbing tank 104 and is provided with a liquid supply port. The liquid supply component 105 can be a structure such as a pipe to realize the transportation of slurry.

[0071] like Figure 1As shown, a drive mechanism can be configured to drive the two helical rods 103 to rotate; this embodiment does not limit this. In one embodiment, the drive mechanism includes a rotary motor 106, two first gears 107, two drive shafts 108, and two second gears 109. One end of each of the two helical rods 103 is rotatably mounted on the wall of the pool body 102. Each of the two helical rods 103 is provided with a first gear 107. Both drive shafts 108 are rotatably mounted on the wall of the pool body 102. The two second gears 109 are respectively sleeved on the two drive shafts 108, with their opposite sides meshing and their opposing sides meshing with the two first gears 107. The rotary motor 106 is fixedly connected to the side wall of the pool body 102, and its output end is connected to one of the helical rods 103.
