Description

Technical Field

[0001] The utility model relates to the technical field of ore production equipment, in particular to an ore powder removal system. Background Art

[0002] Mineral resources are formed naturally through geological movements. For production and utilization, they need to be mined and crushed into products of varying sizes. Depending on the purpose of utilization, product quality requirements also vary. However, mineral fines are generated in every production link, from mining, crushing, screening, grading, and transportation. For products that require controlled fines content in fine ore products, the production process often exceeds the standard for fines, and some of the excess must be removed to meet quality requirements. Existing methods for removing fines often involve flushing with water, which generates a large amount of wastewater during the production process. Subsequent wastewater treatment is complex, requires a large amount of work and energy, and is very costly, making it particularly difficult in areas with water scarcity. In cold regions, freezing water can clog the sieves of screening and grading equipment, freeze transportation equipment, and cause the finished wet material to freeze into lumps, leading to ineffective screening and grading. This can cause production to be sluggish or even impossible. Utility Model Content

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0025] In this utility model, unless otherwise specified or limited, the terms "assemble," "connect," "connect," "fix," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0026] Figure 1 and Figure 2An embodiment of the ore powder removal system of the utility model is shown. The ore powder removal system of this embodiment includes an ore aggregate supply device 1, a powder removal bin 2, an air supply device 3 and a finished material conveying device 4. The powder removal bin 2 is provided with a feed port 21 and a powder discharge port 22 at the top, and a discharge port 23 at the bottom. The discharge end of the ore aggregate supply device 1 is located above the feed port 21 and is used to supply ore aggregate to the feed port 21. The air supply device 3 is connected with the discharge port 23 and is used to supply air into the powder removal bin 2 through the discharge port 23 to blow ore powder toward the powder discharge port 22. The finished material conveying device 4 is provided below the discharge port 23 and is used to receive the ore aggregate falling from the discharge port 23.

[0027] Operation: Ore aggregate supply device 1 supplies ore aggregate to feed port 21. Air supply device 3 supplies air into powder removal bin 2 through discharge port 23, blowing ore powder toward discharge port 22. The ore powder is discharged through discharge port 22, and the ore aggregate, free of ore powder, falls through discharge port 23 to finished material conveyor device 4. This ore fines removal system utilizes water flushing to remove ore fines, which reduces workload and energy consumption, reduces costs, eliminates water waste, and achieves excellent powder removal results.

[0028] Furthermore, in this embodiment, if Figure 2As shown, the lower portion of the powder removal bin 2 is provided with a plurality of graded discharge channels 24 arranged side by side. Each graded discharge channel 24 forms a discharge port 23 at its bottom end. The feed port 21 is located on the right side of the powder removal bin 2. The top right side of each graded discharge channel 24 tilts outward to form an inclined guide surface 5. The graded discharge channels 24 are arranged side by side from left to right, and the inclined guide surfaces 5 are also arranged side by side from left to right. After entering the ore aggregate from the feed port 21, it falls freely, forming a "waterfall" shape, achieving sufficient diffusion of fine aggregate to increase the rejection space. The compressed air supplied by the air supply device 3 enters through the discharge port 23 and diffuses upward. The air moves rapidly upward and collides with the falling finished fine aggregate, carrying away the light and small particles in the diffused fine aggregate. The large and heavy ore particles fall to the finished material conveyor 4 under the action of gravity and are transported by the finished material conveyor 4 to the finished product bin. The discharge ports 23 are arranged side by side. When in use, the air intake of the discharge ports 23 gradually decreases from right to left, meeting the requirements of step-by-step powder removal. That is to say, since the feed port 21 is located on the right side of the powder removal bin 2, the air intake of the discharge ports 23 gradually decreases from right to left, so that the ore aggregates dropped from the rightmost discharge port 23 are the heaviest, and then gradually decrease to the left. The ore aggregates that cannot overcome the upwind resistance and fall are transported to the next inclined guide surface 5 (from right to left) under the action of the wind. In this way, the material is removed step by step to improve the powder removal effect. Each inclined guide surface 5 can be regarded as a first-level inclined guide surface 5, a second-level inclined guide surface 5, a third-level inclined guide surface 5... from right to left. The space above the first-level inclined guide surface 5, the second-level inclined guide surface 5, the third-level inclined guide surface 5... can be regarded as a first-level powder removal space, a second-level powder removal space, a third-level powder removal space... respectively.

[0029] Furthermore, in this embodiment, the inclined guide surface 5 has an inclination angle of 45° to 90°. This facilitates the movement of ore aggregate that cannot overcome the upwind resistance and falls from the inclined guide surface 5 to the next level of inclined guide surface 5 under the action of wind. Optimally, the inclined guide surface 5 has an inclination angle of 50°.

[0030] Furthermore, in this embodiment, the area of ​​the inclined guide surface 5 gradually decreases from right to left. As the ore aggregate gradually decreases from right to left, the area of ​​the inclined guide surface 5 can also gradually decrease from right to left, thereby reducing material and cost waste.

[0031] Furthermore, in this embodiment, the powder removal bin 2 is provided with a primary discharge channel 25 directly below the feed port 21 , and the powder removal bin 2 is provided with an emergency discharge channel 26 on the right side of the primary discharge channel 25 .

[0032] Furthermore, in this embodiment, the ore fines removal system also includes a dust removal device 6 having an air inlet 61, an air outlet 62, and a discharge port 63. The air inlet 61 is connected to the powder discharge port 22, and the air outlet 62 is connected to the discharge port 23. The dust removal device 6 is used to block and discharge the ore fines, and can also connect the powder discharge port 22 and the discharge port 23, so that the air inlet and outlet of the powder removal bin 2 circulate.

[0033] Furthermore, if Figure 1 As shown, in this embodiment, a powder receiving device 64 is provided below the discharge port 63. The ore fines removal system further includes a powder transfer device 7 and a powder tank 8. The powder transfer device 7 is provided between the powder receiving device 64 and the powder tank 8 and is used to transfer the fines on the powder receiving device 64 to the powder tank 8. The powder receiving device 64 is used to receive the fines falling from the discharge port 63, and the powder transfer device 7 is used to transfer the fines on the powder receiving device 64 to the powder tank 8, thereby realizing the recycling of the fines.

[0034] Furthermore, in this embodiment, the ore aggregate supply device 1 includes an ore aggregate supply mechanism 11 and an elevating and conveying mechanism 12. The feed end of the elevating and conveying mechanism 12 is located below the discharge end of the ore aggregate supply mechanism 11, and the discharge end is located above the feed port 21. The ore aggregate supply mechanism 11 supplies ore aggregate to the feed end of the elevating and conveying mechanism 12, and the elevating and conveying mechanism 12 elevates and conveys the ore aggregate to the feed port 21 of the de-dusting bin 2.

[0035] Furthermore, in this embodiment, the finished material conveying device 4 is a belt conveying device.

[0036] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the present invention, or modify it into equivalent embodiments with equivalent variations.
