[0034] Detailed Description Of Preferred Embodiments To make the purpose , technical solutions , and advantages of the present invention clearer, the following further detailed description of the invention is combined with the drawings and examples . It should be understood that the speci fic examples described here are only used to explain the invention and do not limit the invention .

[0035] To address the technical issue of how to avoid washing ore in batches , the present invention provides a slope gravity ore washing system that can continuously wash ore , thereby improving the washing ef ficiency of the ore . It should be noted that the slope gravity ore washing system of the present invention is used for, but not limited to , the smelting of laterite nickel ore . For the sake of convenience in explanation, the following only takes the application of the slope gravity ore washing system in the smelting of laterite nickel ore as an example for illustration, and the principle of the slope gravity ore washing system applied to other types of equipment is essentially the same as that applied in the smelting of laterite nickel ore , which is not repeated here .

[0036] Refer to Figure 1 , which is a structural schematic diagram of the slope gravity ore washing system in an embodiment of the present invention . The slope gravity ore washing system includes a guiding component 100 , a washing component 200 , and a separating component 300 . The guiding component 100 includes a slope body 110 and several guiding plates 120 , with the slope body 110 having an inclined ore washing trough 111 . The washing component 200 introduces water flow into the ore washing trough 111 . The separating component 300 includes a foundation 310 and a screen conveyor belt 320 , with the foundation 310 having a pulp trough 311 , and the screen conveyor belt 320 is positioned above the pulp trough 311 and is used to receive the material discharged from the ore washing trough 111 . The screen conveyor belt 320 retains and conveys the ore in the material , allowing the pulp in the material to permeate into the pulp trough 311 .

[0037] In this embodiment , the ore to be washed is first placed at the top of the ore washing trough 111 . Due to the inclined setting of the ore washing trough 111 , the ore slides along the ore washing trough 111 under the action of gravity, and the washing component 200 introduces water flow to the top of the ore washing trough 111 , using water flow to scrub the sliding ore in the ore washing trough 111 . The water dissolves the clay that is sticky on the surface of the ore to form pulp . The washed ore is received and conveyed by the screen conveyor belt 320 , and the pulp permeates through the screen conveyor belt 320 into the pulp trough 311 , and then the pulp is distributed through the pulp trough 311 . Using the above slope gravity ore washing system, ore can be washed continuously instead of in batches , thereby improving the washing ef ficiency of the ore .

[0038] In some embodiments , the guiding component 100 also includes several guiding plates 120 , which are interlaced within the ore washing trough 111 to form a tortuous guiding channel .

[0039] In some embodiments , the guiding plates 120 have several filter holes 121 .

[0040] In this embodiment , the water flow in the ore washing trough 111 will fall through the filter holes 121 , ensuring that the water flow does not completely flow along the guiding plates 120 . The water flow falling from the filter holes 121 and the water flow along the guiding plates 120 are interlaced, making the water flow in the guiding channel more complex, thereby achieving a more ideal ore washing ef fect .

[0041] In some embodiments , the upper surface of the guiding plates 120 has several baf fles 122 , which are arranged along the length direction of the guiding plates 120 .

[0042] In this embodiment , the baf fles 122 on the upper surface of the guiding plates 120 can cause the water flow to create waves , intensi fy the vibration of the ore sliding along the guiding plates 120 , and scrape the surface of the ore through the baf fles 122 . Under the combined action of the three , the dissolution rate of the clay on the surface of the ore can be accelerated .

[0043] In some embodiments , the washing component 200 also includes several washing pipes 220 , which are arranged along the length direction of the ore washing trough 111 and are positioned within the ore washing trough 111 , with the washing pipes 220 used to spray water into the guiding channel .

[0044] In this embodiment , the washing pipes 220 are positioned above the ore washing trough 111 and can spray water from above the guiding channel . The falling water flow assists in scrubbing the ore , speeding up the washing ef ficiency of the surface soil of the ore .

[0045] Based on the above embodiment , in some embodiments , the washing pipes 220 have several spraying ports 221 .

[0046] In this embodiment , each spraying port 221 can spray water, allowing for a larger area of water spray .

[0047] In some embodiments , the washing component 200 also includes a water supply pump 230 , which pressuri zes water to the flushing pipe 210 and the washing pipes 220 .

[0048] In this embodiment , the water supply pump 230 pressuri zes water to the washing pipes 220 and the flushing pipe 210 , enabling the flushing pipe 210 and the washing pipes 220 to spray water .

[0049] Based on the above embodiment , in some embodiments , a flushing valve 240 is installed between the water supply pump 230 and the flushing pipe 210 , and a washing valve 250 is installed between the water supply pump 230 and the washing pipes 220 .

[0050] In this embodiment , the flushing valve 240 can control the opening and closing of the flushing pipe 210 . When the flushing pipe 210 needs to spray water, the flushing valve 240 can be opened to allow the water supply pump 230 to supply water to the flushing pipe 210 . When the flushing pipe 210 needs to be closed, the flushing valve 240 can be closed . Similarly, the washing valve 250 can control the opening and closing of the washing pipes 220 . When the washing pipes 220 need to spray water, the washing valve 250 can be opened to allow the water supply pump 230 to supply water to the washing pipes 220 . When the washing pipes 220 need to be closed, the washing valve 250 can be closed .

[0051] In some embodiments , the separating component 300 also includes a bridging plate 330 , with one end of the bridging plate 330 connected to the bottom end of the guiding channel and the other end connected to the screen conveyor belt 320 .

[0052] In this embodiment , the bridging plate 330 is connected at both ends to the bottom end of the guiding channel and the screen conveyor belt 320 , allowing the pulp and ore discharged from the guiding channel to cross the gap between the guiding channel and the screen conveyor belt 320 via the bridging plate 330 .

[0053] Based on the above embodiment , in some embodiments , one end of the bridging plate 330 is rotatably mounted on the slope body 110 , and the bridging plate 330 can stay at any position on its rotation tra j ectory .

[0054] In this embodiment , by rotating the bridging plate 330 , the angle of the bridging plate 330 can be adj usted to adapt to the guidance needs of the ore and pulp .

[0055] In some embodiments , the slope body 110 is a metal slope body 110 .

[0056] In this embodiment , the slope body 110 has suf ficient structural strength .

[0057] Additionally, the present invention also provides a slope gravity ore washing method, which is used for the above slope gravity ore washing system, and includes :

[0058] S I : Allowing the ore to be washed to slide down the inclined ore washing trough;

[0059] 52 : Introducing water flow to wash the ore in the ore washing trough;

[0060] 53 : Receiving the sliding ore in the ore washing trough and separating the ore from the pulp .

[0061] In this embodiment , the ore slides along the ore washing trough, and the water flow washes the ore in the washing trough, dissolving the clay that is sticky on the surface of the ore to form pulp, and finally separating the pulp and the ore to complete the washing of the ore .

[0062] In some embodiments , the direction of the water flow is interlaced with the sliding direction of the ore .

[0063] In this embodiment , the water flow and the ore are made to slide in interlaced directions , increasing the relative speed di f ference between the water flow and the ore , thereby achieving a more ideal washing ef fect .

[0064] For a better understanding of the invention, the technical solutions of the invention are further described in detail below in conj unction with Figures 1 to 4 :

[0065] Firstly, the ore to be washed is placed at the top of the ore washing trough 111 . Due to the inclined setting of the ore washing trough 111 , the ore slides along the guiding channel under the action of gravity . The upper surface of the guiding plates 120 has several baf fles 122 , which can cause the water flow to create waves , intensi fy the vibration of the ore sliding along the guiding plates 120 , and scrape the surface of the ore through the baf fles 122 . Under the combined action of the three , the dissolution rate of the clay on the surface of the ore can be accelerated . The flushing pipe 210 introduces water flow to the top of the ore washing trough 111 , using the water flow to scrub the ore sliding in the guiding channel . The washing pipes 220 are positioned above the ore washing trough 111 and can spray water from above the guiding channel , assisting in scrubbing the ore with the falling water flow and speeding up the washing ef ficiency of the surface soil of the ore . The water dissolves the sticky clay on the surface of the ore to form pulp . The washed ore is received and transported away by the screen conveyor belt 320 , while the pulp permeates through the screen conveyor belt 320 and falls into the pulp trough 311 . Subsequently, the pulp is distributed through the pulp trough 311 . Utili zing the aforementioned slope gravity ore washing system, ore can be continuously washed instead of in batches , improving the washing ef ficiency of the ore .

[0066] The above detailed description of embodiments of the invention does not constitute a limitation on the scope of protection of the invention . Any other corresponding changes and modi fications made in accordance with the technical ideas of the invention should be included within the scope of the claims of the invention .
