[0001] The invention relates to the technical field of nickel ore washing, and in particular to an ore washing machine. Background Art

[0002] Laterite nickel ore is a loose clay-like multi-mineral aggregate formed by long-term weathering, leaching, impregnation, alteration and other geological processes of nickel-bearing olivine bedrock in tropical or subtropical regions, accompanied by metal components such as nickel, cobalt, chromium, magnesium, and aluminum. At present, the hydrometallurgical route of sulfuric acid leaching under high temperature and high pressure conditions is one of the mainstream smelting processes of laterite nickel ore. Before acid leaching, the ore needs to be washed, re-selected, ball-milled, magnetically separated, and thickened to form a slurry to be acid-leached. Among them, the role of the washing process is to screen out the large gravel in the laterite nickel ore, and the minerals containing metals such as nickel and cobalt are mixed with water to form a slurry. At present, the equipment generally used in the washing process is a washing machine.

[0003] The ore washer in the prior art generally includes a cylinder, a feed port is connected to the left side of the cylinder, a washing chamber is located on the left side of the cylinder, a screening chamber is located on the right side of the cylinder, and a stirring mechanism is also provided throughout the cylinder. However, with the cooperation of the stirring mechanism, the mud ore on the gravel is not completely cleaned by adopting the mode of the washing chamber plus the screening chamber, and mud ore still remains on the gravel after passing through the ore washer. Summary of the invention

[0004] The object of the present invention is to provide a ore washer to more fully wash away the mud ore on the gravel, optimize the ore washing effect and improve the ore washing quality.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] This embodiment provides a ore washing machine. Specifically, Figure 1 As shown, the ore washing machine includes an inner cylinder 100 , an outer cylinder 200 , a rotary driving member 300 and a liquid supply member 400 .

[0042] See also Figure 1 and Figure 2 As shown, the inner cylinder 100 includes a plurality of ore-washing and separation assemblies, which are sequentially connected along the material conveying direction. Each ore-washing and separation assembly includes an ore-washing cylinder section 110 and an intercepting and separating cylinder section 120 which are sequentially connected along the material conveying direction. A plurality of discharge ports are distributed on the intercepting and separating cylinder section 120. An outer cylinder 200 is sleeved at intervals on the outer periphery of each intercepting and separating cylinder section 120, and a discharge area is formed between the intercepting and separating cylinder section 120 and the outer cylinder 200. The rotary drive member 300 is connected to the inner cylinder 100 and is used to drive the inner cylinder 100 to rotate. The liquid supply member 400 is used to supply liquid into the ore-washing cylinder section 110.

[0043] During operation, nickel ore is put into the inner cylinder 100 from the feed port of the ore washer, and first passes through the ore washing cylinder section 110. The liquid supply part 400 supplies liquid to the ore washing cylinder section 110. The water flow and the material are fully contacted, mixed and stirred in the ore washing cylinder section 110. The rotary drive part 300 drives the inner cylinder 100 to rotate to wash the mud ore coated on the gravel. The material in the washing process moves along the material conveying direction and enters the interception and separation cylinder section 120. Most of the mud ore passes through the interception and separation cylinder section 120 with the water through the discharge port and is discharged to the discharge area between the interception and separation cylinder section 120 and the outer cylinder 200. The gravel with residual mud attached to it enters the next ore-washing section 110 for ore washing along the material conveying direction. The liquid supply component 400 supplies liquid to the ore-washing section 110. The water flow and the material are fully contacted, mixed and stirred in the ore-washing section 110. The rotary drive component 300 drives the ore-washing section 110 to rotate to clean the residual mud on the gravel. The material in the cleaning process moves along the material conveying direction and enters the next intercepting and separating section 120. The remaining mud passes through the intercepting and separating section 120 with the water through the discharge port and is discharged to another discharge area between the intercepting and separating section 120 and the outer tube 200.

[0044] In the ore washer provided in this embodiment, the ore washing section 110 of the inner cylinder 100 is used for ore washing, the interception and separation section 120 is used for separation, and the outer cylinder 200 cooperates with the interception and separation section 120 to form a discharge area. This structural cooperation allows the ore washing and separation process to proceed in an orderly manner, thereby improving the working efficiency and separation accuracy. The interception and separation section 120 continuously throws out the mud ore, and the outer cylinder 200 collects the mud ore outside the interception and separation section 120 to avoid splashing of the mud ore. The rotating drive member 300 drives the inner cylinder 100 to rotate, so that the material can fully move and mix, ensuring the uniform contact between the water flow and the material during the ore washing process, and enhancing the ore washing effect. The liquid supply member 400 supplies liquid to the ore washing section 110, and the water flow interacts with the rotating ore washing section 110, so that the water flow can be evenly distributed in the material, thereby enhancing the cleaning effect. It can be understood that the amount and pressure of the liquid supply can be adjusted according to the needs of ore washing to adapt to different ore characteristics and mud content. The ore washing cylinder section 110 in each ore washing and separation component washes the ore first, and the intercepting separation cylinder section 120 performs separation. By adopting multiple ore washing and separation components, the ore material can be efficiently screened through the processes of primary screening and fine screening, thus realizing a continuous and efficient ore washing and separation process, and being able to more fully wash away the mud ore on the gravel, thereby optimizing the ore washing effect and improving the ore washing quality.

[0045] like Figure 3As shown, optionally, the intercepting and separating barrel section 120 includes a plurality of blocking bars 121 extending in the material conveying direction, each blocking bar 121 is arranged at intervals in the circumferential direction, and the above-mentioned discharge outlet is formed between adjacent blocking bars 121. On the one hand, the extending direction of the blocking bars 121 is perpendicular to the rotation direction of the inner barrel 100. With the driving of the rotating driving member 300, the blocking bars 121 have an excellent scraping effect on the gravel, which is conducive to scraping off the residual ore mud on the gravel and improving the ore washing effect; on the other hand, the discharge outlet formed by the spacing of the blocking bars 121 is conducive to the rapid passage and discharge of materials, reducing the possibility of material clogging at the discharge outlet, and ensuring the smooth progress of the separation process.

[0046] like Figure 3 As shown, in this embodiment, the ore washing and separation assembly further comprises a fixing ring 122, and each blocking bar 121 is fixed on the fixing ring 122, and the fixing ring 122 ensures the structural reliability of the interception and separation cylinder section 120. The blocking bar 121 is in the shape of a long strip.

[0047] Optionally, the ore washing and separation assembly further includes a plurality of annular water retaining parts, which are arranged on the inner wall of the ore washing barrel section 110 and protrude inwardly from the inner wall of the ore washing barrel section 110. The annular water retaining parts enable the ore washing barrel section 110 to accommodate gravels with mud ore attached thereto and washing water, prolonging the residence time of the materials in the ore washing barrel section 110, so as to more fully wash the gravels with mud ore attached thereto, thereby improving the ore washing effect.

[0048] In some embodiments, along the material conveying direction, the inner cylinder 100 is inclined from top to bottom, and an annular water retaining portion is provided at one end of the ore-washing cylinder section 110 close to the intercepting and separating cylinder section 120. The annular water retaining portion limits the flow rate and flow of water flowing to the intercepting and separating cylinder section 120, thereby ensuring the cleaning effect of the ore-washing cylinder section 110.

[0049] In other embodiments, an annular water retaining part is provided at both ends of the washing tube section 110 in the material conveying direction. The annular water retaining part is provided at both ends of the material conveying direction, which can achieve dual blocking and flow limiting effects, more effectively control the flow speed and direction of the material and water flow, and enhance the washing effect. The annular water retaining parts at both ends can effectively prevent the backflow of the material and water flow during the washing process, ensuring the unidirectionality and stability of the washing process.

[0050] like Figure 2 As shown, in this embodiment, the inner diameter of the ore-washing barrel section 110 is larger than the inner diameter of the intercepting and separating barrel sections 120 at both ends thereof, the inner walls at both ends of the ore-washing barrel section 110 extend radially inward to form an annular water retaining portion, and the inner diameter of the intercepting and separating barrel section 120 is set to be the same as the inner diameter of the water retaining ring. In this embodiment, the ends of the retaining bars 121 in the length direction are connected to the adjacent annular water retaining portions.

[0051] like Figure 2As shown, optionally, the inner wall of the ore-washing barrel section 110 is provided with a plurality of disturbance bars 111, and the disturbance bars 111 extend along the material conveying direction. When the gravel with mud ore adhered thereto passes through the ore-washing barrel section 110, it can be driven by the disturbance bars 111 to rotate with the ore-washing barrel section 110 to a certain height and then fall back, promoting a greater impact between the gravel and the water flow, so that the mud ore coated on the gravel is separated from the gravel. When the ore-washing barrel section 110 rotates, the disturbance bars 111 enhance the agitation of the material and the water flow, enhance the mixing and stirring effect of the material and the water flow, and make the ore washing more complete. Increase the collision and friction between the materials, and improve the efficiency of cleaning the mud ore on the gravel.

[0052] like Figure 2 As shown, optionally, along the material conveying direction, the disturbance bar 111 is inclined toward the rotation direction of the inner cylinder 100, and the angle formed by the disturbance bar 111 and the generatrix of the ore-washing cylinder section 110 is smaller than the angle of the ore-washing cylinder section 110 relative to the horizontal plane. The inclination direction of the disturbance bar 111 is matched with the rotation direction of the inner cylinder 100, which can more effectively stir the material and water flow, and further enhance the mixing and cleaning effect. When the inclined disturbance bar 111 pushes the material, it generates a component force along the conveying direction, which helps the material to be conveyed forward. The disturbance bar 111 forms a smaller angle with the generatrix of the ore-washing cylinder section 110 and is smaller than the angle of the ore-washing cylinder section 110 relative to the horizontal plane, which can control the material conveying of the disturbance bar 111 not to be too fast, and ensure that the material stays in the ore-washing cylinder section 110 for a longer time, so as to better wash the gravel, reduce the waste of water resources, and improve the ore-washing effect.

[0053] It should be noted that when the discharge speed of the ore washing cylinder section 110 needs to be accelerated, the rotation direction of the inner cylinder 100 can be changed. At this time, the disturbance bar 111 is more inclined to push the material in the material conveying direction.

[0054] like Figure 2 As shown, optionally, a discharge port 201 is provided at the bottom of the outer cylinder 200. The discharge port 201 at the bottom of the mud outer cylinder 200 is located relatively low, and the mud collected in the discharge area between the outer cylinder 200 and the interception and separation cylinder section 120 naturally flows to the discharge port 201 under the action of gravity, and is discharged smoothly and quickly.

[0055] like Figure 1 As shown, optionally, the inner cylinder 100 is tilted from top to bottom along the material conveying direction. By utilizing the gravity, the material moves more smoothly along the inner cylinder 100 from the feed end to the discharge end, realizing the automatic conveyance of the material along with the ore washing process, reducing the need for additional power devices to drive the material movement, thereby reducing costs. It is understandable that the tilt angle of the inner cylinder 100 is determined according to the type of ore and the adaptability of the ore washing needs, and is not specifically limited here.

[0056] like Figure 1As shown, in this embodiment, the feed end of the inner cylinder 100 is at its upper end, which is also the upper end of the first ore washing cylinder section 110, and the gravel to be cleaned enters the inner cylinder 100 from here; the discharge end of the inner cylinder 100 is at its lower end, which is also the lower end of the last intercepting separation cylinder section 120, and the gravel that has completed cleaning is discharged from the discharge end.

[0057] like Figure 1 As shown, optionally, the ore washer further includes a support frame 500, and the ore washing cylinder section 110 is rotatably connected to the support frame 500. The support frame 500 provides a solid support for the inner cylinder 100 through the ore washing cylinder section 110, ensuring that the inner cylinder 100 maintains a stable position and posture during rotation and operation. Moreover, the ore washing cylinder section 110 is rotatably connected to the support frame 500, which can avoid the interference of the support frame 500 with the discharge of mud from the interception and separation cylinder section 120, and also avoid interference with the outer cylinder 200, ensuring that the interception and separation cylinder section 120 and the outer cylinder 200 can independently and efficiently complete the separation operation.

[0058] In this embodiment, a rotating bearing (not shown) is provided between the support frame 500 and the ore-washing barrel section 110. The rotating bearing has a first part and a second part that can rotate relatively, the first part is fixed to the support frame 500, and the second part is fixed to the ore-washing barrel section 110.

[0059] like Figure 1 and Figure 2 As shown, optionally, the liquid supply part 400 includes a flushing pipe 401 and a liquid supply pump (not shown in the figure), the flushing pipe 401 is connected to the liquid supply pump, and the flushing pipe 401 is arranged in the inner cylinder 100 along the material conveying direction, and a plurality of liquid spray holes are arranged on the flushing pipe 401. Specifically, the flushing pipe 401 passes through each washing cylinder section 110 and the intercepting separation cylinder section 120 in sequence, and the liquid spray holes thereon spray water into the corresponding cylinder section to wash the mud ore on the gravel. The multiple liquid spray holes on the flushing pipe 401 are distributed along the material conveying direction, which can provide a uniform water flow for the inner cylinder 100, ensuring that the material can be fully washed during the entire washing process. The flushing pipe 401 is arranged in the inner cylinder 100, and can directly transport water to the material, so as to achieve a deeper washing and improve the washing efficiency of the mud ore.

[0060] like Figure 1-Figure 3 As shown, optionally, two ore washing and separation assemblies are provided. That is, two ore washing cylinder sections 110 and two interception separation cylinder sections 120 are provided. The two ore washing and separation assemblies can perform the processes of primary washing and fine washing in sequence, thereby improving the ore washing quality. Setting two ore washing and separation assemblies not only improves the ore washing effect, but also controls the complexity and cost of the equipment, thereby achieving a good balance between effect and cost.

[0061] In this embodiment, the nickel ore first passes through the first ore washing section 110, and the flushing component sprays water to clean the mud ore coated on the gravel, and the ore is discharged from the first intercepting and separating section 120 to the first outer cylinder 200. Most of the mud ore passes through the first intercepting and separating section 120 with the water and leaks into the first outer cylinder 200; the gravel with the remaining mud ore attached enters the second ore washing section 110 for ore washing, and the flushing component sprays water to clean the mud ore coated on the gravel, and the ore is discharged from the second intercepting and separating section 120 to the second outer cylinder 200.

[0062] like Figure 1 As shown, optionally, the rotary drive member 300 includes a driver 301 and a driving wheel 302, the output end of the driver 301 is coaxially fixed with the driving wheel 302, and the driving wheel 302 abuts against the inner cylinder 100. The output end of the driver 301 rotates so that the driving wheel 302 drives the inner cylinder 100 to rotate. It should be noted that the driver 301 has multiple implementations. In this embodiment, the driver 301 includes a motor, a coupling and a reducer, and the motor, the coupling and the reducer are connected in sequence to output rotation.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
