Description

Technical Field

[0001] The present invention relates to the field of ore washing and desludging, and in particular to a slope gravity ore washing system and method. Background Art

[0002] In the current hydrometallurgical process of laterite nickel ore, the nickel ore must first be beneficiated. The most commonly used is a drum ore washer, which is used to separate the coarse ore from the laterite ore.

[0003] The drum ore washer, as described in patent application number CN201910794537.2, includes several screen drums, each of which forms a washing chamber. The rotation of the screen drums combined with the spraying of a first cleaning assembly allows for simultaneous ore cleaning and grading, allowing the ore to be directly graded and discharged after cleaning. However, this ore washing method can only clean the ore in batches, limiting its efficiency.

[0004] Therefore, how to continuously clean the ore is a technical problem that needs to be solved urgently. Summary of the Invention

[0005] The purpose of the present invention is to overcome the above technical deficiencies and propose a slope gravity washing system and method to solve the technical problem of how to continuously wash the ore in the prior art.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: In one aspect, the present invention provides a slope gravity washing system comprising: A guide assembly includes a slope with an inclined ore washing trough; a rinse assembly, which introduces water flow into the top end of the guide groove; and The separation component includes a foundation and a screen conveyor belt. The foundation is provided with a slurry trough. The screen conveyor belt is erected above the slurry trough and is used to receive the material discharged from the ore washing trough. The filter conveyor belt retains and transports the ore in the material and allows the slurry in the material to penetrate into the slurry trough. In some embodiments, the guide assembly further comprises a plurality of guide plates, and the plurality of guide plates are staggeredly arranged in the ore washing trough to enclose a tortuous guide channel in the ore washing trough.

[0007] In some embodiments, the guide plate is provided with a plurality of filter holes.

[0008] In some embodiments, the upper surface of the guide plate has a plurality of spacers, and the plurality of spacers are arranged along the length direction of the guide plate.

[0009] In some embodiments, the rinsing assembly includes a flushing pipe, which is installed on the top of the ore washing trough to introduce water into the ore washing trough.

[0010] In some embodiments, the washing assembly further includes a plurality of washing pipes, which are arranged along the length direction of the ore washing trough and are installed in the ore washing trough. The washing pipes are used to spray water into the guide channel.

[0011] In some embodiments, the separation assembly further includes a lap plate, one end of the lap plate is lapped on the bottom end of the guide channel, and the other end of the lap plate is lapped on the screen conveyor belt.

[0012] In some embodiments, one end of the lap plate is rotatably mounted on the slope, and the lap plate can stay at any position on its rotation trajectory.

[0013] On the other hand, the present invention also provides a slope gravity ore washing method, which is used for the above-mentioned slope gravity ore washing system, and comprises: S1, let the ore to be cleaned slide along the inclined washing trough; S2, introducing water flow for washing ore into the ore washing tank; S3. The ore that slides down is received in the ore washing trough, and the ore and slurry are separated from each other.

[0014] In some embodiments, the flow direction of the introduced water flow and the sliding direction of the ore are staggered with each other.

[0015] The ore to be cleaned is first placed at the top of the washing trough. Due to the inclined configuration of the trough, the ore slides along the trough under the action of gravity. A flushing pipe directs water to the top of the trough, using the water flow to flush the ore as it slides within. The water dissolves the dirt adhering to the ore, forming a slurry. The cleaned ore is then picked up and transported by a mesh conveyor belt, while the slurry passes through the mesh conveyor belt and falls into the slurry trough, where it is then distributed. This slope gravity washing system allows the ore to be cleaned continuously, rather than in batches, improving cleaning efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be 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 the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem of how to avoid washing ore in batches, the present invention provides a slope gravity ore washing system, which can continuously wash the ore and improve the ore washing efficiency.

[0019] It should be noted that the slope gravity washing system of the present invention is used for but not limited to the smelting of laterite nickel ore. For the convenience of explanation, in the present invention, only the application of the slope gravity washing system to the smelting of laterite nickel ore is used as an example for explanation. The principle of applying the slope gravity washing system to other types of equipment is essentially the same as the principle applied to the smelting of laterite nickel ore, and will not be repeated here.

[0020] See also Figure 1 , Figure 1 This is a schematic diagram of the structure of a slope gravity ore washing system according to one embodiment of the present invention. The slope gravity ore washing system includes a guide assembly 100, a rinse assembly 200, and a separation assembly 300. The guide assembly 100 includes a slope 110 and a plurality of guide plates 120. The slope 110 is provided with an inclined ore washing trough 111. The rinse assembly 200 introduces water into the ore washing trough 111. The separation assembly 300 includes a foundation 310 and a screen conveyor belt 320. The foundation 310 is provided with a slurry trough 311. The screen conveyor belt 320 is installed above the slurry trough 311 and is used to receive material discharged from the ore washing trough 111. The screen conveyor belt 320 retains and transports ore in the material and allows the slurry in the material to penetrate into the slurry trough 311.

[0021] In this embodiment, the ore to be cleaned is first placed at the top of the ore washing trough 111. Because the ore washing trough 111 is tilted, the ore slides along the ore washing trough 111 under the action of gravity. The elution assembly 200 introduces water flow to the top of the ore washing trough 111, using the water flow to flush the ore sliding in the ore washing trough 111. The water flow dissolves the dirt adhering to the ore to form ore slurry. The cleaned ore is received and transported by the mesh conveyor belt 320, and the ore slurry passes through the mesh conveyor belt 320 and falls into the ore slurry trough 311, and then the ore slurry is distributed through the ore slurry trough 311. Utilizing the above-described slope gravity ore washing system, the ore can be cleaned continuously, rather than in batches, thereby improving the ore cleaning efficiency.

[0022] In some embodiments, the guide assembly 100 further includes a plurality of guide plates 120 . The plurality of guide plates 120 are staggeredly disposed in the ore washing trough 111 to enclose a tortuous guide channel in the ore washing trough 111 .

[0023] In some embodiments, the guide plate 120 defines a plurality of filter holes 121 .

[0024] In this embodiment, the water flowing in the ore washing trough 111 will fall through the filter holes 121, so that the water flow will not flow completely along the guide plate 120. The water flow falling from the filter holes 121 and the water flow along the guide plate 120 are intertwined with each other, making the water flow situation in the guide channel more complicated, thereby obtaining a more ideal ore washing effect.

[0025] In some embodiments, the upper surface of the guide plate 120 has a plurality of spacer bars 122 , and the plurality of spacer bars 122 are arranged along the length direction of the guide plate 120 .

[0026] In this embodiment, the upper surface of the guide plate 120 has a plurality of partition bars 122. On the one hand, the partition bars 122 can cause the water flow to stir up waves, and on the other hand, they can intensify the vibration of the ore sliding along the guide plate 120. The surface of the ore can also be scraped by the partition bars 122. Under the combined action of the three, the dissolution rate of the soil on the surface of the ore can be accelerated.

[0027] In some embodiments, the washing assembly 200 further includes a plurality of washing pipes 220 , which are arranged along the length of the ore washing trough 111 and are installed in the ore washing trough 111 . The washing pipes 220 are used to spray water into the guide channel.

[0028] In this embodiment, the rinsing pipe 220 is installed above the ore washing trough 111. The rinsing pipe 220 can spray water from above the guide channel. The falling water flow helps to flush the ore, thereby accelerating the washing efficiency of the soil on the ore surface.

[0029] Based on the above embodiments, in some embodiments, the rinse pipe 220 is provided with a plurality of injection ports 221 for spraying water.

[0030] In this embodiment, each of the injection ports 221 can inject water, thereby injecting water over a wider range.

[0031] In some embodiments, the rinse assembly 200 further includes a water supply pump 230 , which pressurizes water to the flushing pipe 210 and the rinse pipe 220 .

[0032] In this embodiment, the water supply pump 230 pressurizes water to the rinsing pipe 220 and the flushing pipe 210 , so that the flushing pipe 210 and the rinsing pipe 220 can spray water.

[0033] On the basis of the above embodiments, in some embodiments, a flushing valve 240 is installed between the water supply pump 230 and the flushing pipe 210 , and a rinsing valve 250 is installed between the water supply pump 230 and the rinsing pipe 220 .

[0034] In this embodiment, the flushing valve 240 can be used to control the on / off of the flushing pipe 210. When the flushing pipe 210 needs to be sprayed with water, the flushing valve 240 can be opened, and water can be supplied to the flushing pipe 210 via the water supply pump 230. When the flushing pipe 210 needs to be closed, the flushing valve 240 can be closed. The rinsing valve 250 can be used to control the on / off of the rinsing pipe 220. When the rinsing pipe 220 needs to be sprayed with water, the rinsing pipe 220 can be opened, and water can be supplied to the rinsing pipe 220 via the water supply pump 230. When the rinsing pipe 220 needs to be closed, the rinsing valve 250 can be closed.

[0035] In some embodiments, the separation assembly 300 further includes a lap plate 330 , one end of the lap plate 330 is lapped on the bottom end of the guide channel, and the other end of the lap plate 330 is lapped on the screen conveyor belt 320 .

[0036] In this embodiment, both ends of the lap plate 330 are respectively overlapped with the bottom end of the guide channel and the screen conveyor belt 320, so that the slurry and ore discharged from the guide channel can cross the gap between the guide channel and the screen conveyor belt 320 through the lap plate 330.

[0037] On the basis of the above embodiments, in some embodiments, one end of the lap plate 330 is rotatably mounted on the slope 110 , and the lap plate 330 can stay at any position on its rotation trajectory.

[0038] In this embodiment, the placement angle of the connecting plate 330 can be adjusted by rotating the connecting plate 330, so that the inclination angle of the connecting plate 330 can adapt to the guiding requirements of the ore and the slurry.

[0039] In some embodiments, the slope 110 is a metal slope 110 .

[0040] In this embodiment, the slope body 110 has sufficient structural strength.

[0041] In addition, the present invention also provides a slope gravity ore washing method, which is used for the above-mentioned slope gravity ore washing system, and comprises: S1, let the ore to be cleaned slide along the inclined washing trough; S2, introducing water flow for washing ore into the ore washing tank; S3. The ore that slides down is received in the ore washing trough, and the ore and slurry are separated from each other.

[0042] In this embodiment, the ore is allowed to slide along the ore washing trough, and the water flow washes the ore in the ore washing trough, so that the water flow dissolves the mud adhering to the surface of the ore to form ore pulp, and finally the ore pulp and ore are separated from each other to complete the ore cleaning.

[0043] Based on the above embodiments, in some of the embodiments, the flow direction of the introduced water flow and the sliding direction of the ore are staggered with each other.

[0044] In this embodiment, the flow directions of the ore and the water flow are staggered, so that the relative speed difference between the water flow and the ore is larger, thereby obtaining a more ideal flushing effect.

[0045] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail: First, the ore to be cleaned is placed at the top of the ore washing trough 111. Because the ore washing trough 111 is tilted, the ore slides along the guide channel under the action of gravity. The upper surface of the guide plate 120 is provided with a number of spacers 122. These spacers 122 not only create waves in the water flow, but also intensify the vibration of the ore sliding along the guide plate 120. The spacers 122 also scrape the ore surface. The combined effect of these three factors accelerates the dissolution of soil on the ore surface. The flushing pipe 210 directs water flow to the top of the ore washing trough 111, using the water flow to flush the ore sliding in the guide channel. The elution pipe 220 is mounted above the ore washing trough 111 and can spray water from above the guide channel. The falling water flow assists in flushing the ore, accelerating the efficiency of flushing the soil on the ore surface. The water dissolves the dirt adhering to the ore to form slurry. The cleaned ore is picked up and transported by the mesh conveyor belt 320. The slurry passes through the mesh conveyor belt 320 and falls into the slurry tank 311, where it is then distributed. The above-described slope gravity washing system allows for continuous ore washing, rather than batch-by-batch washing, improving ore cleaning efficiency.

[0046] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
