Description

Technical Field

[0001] The present invention relates to the technical field of hematite ore mining, and particularly to a wet separation device for impurities in hematite ore particles. Background Art

[0002] Hematite is a mineral with a chemical composition of Fe2O3, which can be divided into crystalline and cryptocrystalline types. The crystalline type is mostly iron-black to steel-gray, with a semi-metallic luster, and the cryptocrystalline type is ochre-red with a dull luster. The streak of both types is cherry-red. Its hardness is 5.5 - 6.0. It is produced in sedimentary rock deposits and is an important mineral raw material for iron smelting. When mining hematite, it needs to be crushed. The small crushed pieces of hematite after crushing are mostly dark purple, generally 5.3 cm long, 3.2 cm wide, and 2.8 cm thick. They are mostly polyhedral, with grinding and use marks on the surface and can leave red marks.

[0003] Currently, after the mined hematite is crushed, it is still necessary to separate the impurities from the small crushed pieces of hematite. Since there are many other viscous and water-soluble impurities such as soil doped inside the hematite, and these impurities adhere to the internal pores of the hematite, it is very difficult to remove them by traditional screening or sand blowing methods.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

Detailed implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-7 , the present invention provides a technical solution: a wet separation device for impurities in hematite ore particles, including a fixed cylinder 1. An installation flange ring 4 is provided on the outer surface of the fixed cylinder 1 near the top edge. A material cylinder 42 is arranged inside the fixed cylinder 1. An annular ring 18 is fixed at the bottom of the material cylinder 42 near the outer surface edge. A plurality of on-off control devices are arranged inside the annular ring 18. A plurality of pressing and positioning components for pressing and guiding the material cylinder 42 are arranged inside the side wall of the fixed cylinder 1. A driving component is arranged on the inner bottom surface of the fixed cylinder 1; A buffer cavity 13 is provided in the middle part of the side wall of the fixed cylinder 1. A plurality of second grid openings 14 are equidistantly provided along the circumferential direction on one inner wall of the buffer cavity 13. The plurality of second grid openings 14 all penetrate through to the inside of the fixed cylinder 1 correspondingly. Two water supply pipes 3 penetrating through to the inside of the buffer cavity 13 are provided on the outer surface of the fixed cylinder 1. An air supply cavity 24 is provided in the side wall of the fixed cylinder 1 near the bottom edge. Two air supply pipes 2 communicating with the inside of the air supply cavity 24 are fixed on the outer surface of the fixed cylinder 1. A conical block 6 is fixed in the middle of the inner bottom surface of the material cylinder 42. A water pumping connection pipe 5 is fixed at the top of the conical block 6. A plurality of side openings 7 are equidistantly provided along the circumferential direction on the outer surface of the water pumping connection pipe 5 near the bottom edge. An inverted trapezoidal groove 15 is provided in the inner bottom surface of the material cylinder 42 near the edge. A plurality of first grid openings 12 penetrating through to the outside are equidistantly provided on both inner walls of the material cylinder 42. The plurality of first grid openings 12 all communicate with the plurality of second grid openings 14 correspondingly.

[0020] The achieved effect is that, by providing an on-off control device, a pressing and positioning component, and a driving component, during the process of separating impurities from the broken pieces of hematite ore containing impurities, gas can be gradually supplied into it to form bubbles. Through the impact of the bubbles on the concave and convex parts of the outer surface of the broken pieces of hematite ore, the impurities attached to the concave and convex parts can be removed, and a mixed solution is formed between the impurities and the water flow, so as to achieve the purpose of removing impurities from the broken pieces of hematite ore and cleaning the broken pieces of hematite ore. The conical block 6 is fixed on the inner bottom surface of the material cylinder 42, so that the broken pieces of hematite ore stored in the material cylinder 42 can be stacked on both sides, which is convenient for subsequent rotation to generate centrifugal force and for sending bubbles from the bottom of the material cylinder 42 to clean the impurities on the broken pieces of hematite ore. At the same time, the water pumping connection pipe 5 is fixed at the top of the conical block 6. Through the water pumping connection pipe 5, the water flow mixed with impurities above the inside of the material cylinder 42 can be pumped out. The first grid openings 12 are correspondingly communicated with the plurality of second grid openings 14, so as to facilitate the supply of water flow into the material cylinder 42 to clean the broken pieces of hematite ore.

[0021] Such as Figure 3 、 Figure 4 and Figure 5As shown, the driving assembly includes a motor 19, which is installed inside the fixed cylinder 1 near the bottom edge. The output end of the motor 19 penetrates into the inside of the fixed cylinder 1. A friction disc 20 is rotatably arranged on the inner bottom surface of the fixed cylinder 1. The output end of the motor 19 is fixed to the bottom of the friction disc 20. An annular air chamber 21 is formed on the inner bottom surface of the fixed cylinder 1. A plurality of arc-shaped protrusions 43 are fixedly arranged at equal intervals along the circumferential direction on the inner bottom surface of the annular air chamber 21. A friction plate 33 is fixed to the bottom of the material cylinder 42. The friction plate 33 is frictionally engaged with the friction disc 20. The annular ring 18 is located inside the annular air chamber 21, and the outer and inner sides of the annular ring 18 are respectively in contact with the two inner walls of the annular air chamber 21. Limiting grooves 8 are formed on both inner walls of the fixed cylinder 1 near the top edge. A limiting block 9 is slidably arranged between the inner walls of the two limiting grooves 8. An active ring 10 is fixed between the opposite sides of the two limiting blocks 9. An annular sliding groove 11 is formed at the bottom of the active ring 10. The top of the material cylinder 42 is slidably engaged inside the annular sliding groove 11.

[0022] The achieved effect is that the motor 19 drives the friction disc 20 to rotate. Since the friction disc 20 is frictionally engaged with the friction plate 33, the material cylinder 42 can be driven to rotate. And under the action of the pressing and positioning assembly, the frictional engagement between the friction disc 20 and the friction plate 33 can be ensured to be stable and firm. When driving the material cylinder 42 to rotate, since the top of the material cylinder 42 is slidably engaged inside the annular sliding groove 11 at the bottom of the active ring 10, the top of the material cylinder 42 can be prevented from shaking during rotation. At the same time, when the material cylinder 42 slides downward along the fixed cylinder 1, through the mutual engagement of the limiting groove 8 and the limiting block 9, its sliding can be made more stable.

[0023] Such as Figure 3 、 Figure 4 and Figure 6As shown in the figure, the pressing and positioning assembly includes a push rod 39. A movable cavity 35 is formed in the side wall of the fixed cylinder 1 below the air supply cavity 24. A movable block 36 is slidably arranged between the inner walls of the movable cavity 35. One end of the push rod 39 is fixed to one side of the movable block 36. The other end of the push rod 39 slidably penetrates into the fixed cylinder 1. A dial block 40 is fixed to the other end of the push rod 39. A ball 41 is rotatably arranged at the bottom of the dial block 40. An annular clamping groove 16 is formed in the outer surface of the cartridge 42 near the bottom edge. An arc-shaped raceway 17 is formed in the inner bottom surface of the annular clamping groove 16. The dial block 40 is located inside the annular clamping groove 16. The ball 41 is in rolling connection with the inside of the arc-shaped raceway 17. There is a gap between the outer surface of the cartridge 42 below the annular clamping groove 16 and the inner wall of the fixed cylinder 1. A hollow cavity 38 is formed in the movable block 36 near one side edge. A plurality of filter ports 34 penetrating to the outer surface are equidistantly arranged along the circumferential direction of the inner wall of the hollow cavity 38. A restraint spring 37 is fixed to the other side of the movable block 36. One end of the restraint spring 37 is fixed to the inner wall of one side of the movable cavity 35. An air supply channel 22 is formed in the side wall of the fixed cylinder 1 at the bottom edge. One end of the air supply channel 22 penetrates to the inner bottom surface of the annular air cavity 21. The other end of the air supply channel 22 is provided with a drainage hole 23. One end of the drainage hole 23 penetrates to the inside of the movable cavity 35. A through hole 25 is formed in the inner bottom surface of the air supply cavity 24. The through hole 25 penetrates to the inside of the movable cavity 35, and the through hole 25 is directly above the drainage hole 23.

[0024] The achieved effect is that during the downward sliding of the cartridge 42, when the outer surface of the bottom of the cartridge 42 is in contact with the dial block 40, the dial block 40 will be pushed towards the inner wall of the fixed cylinder 1, causing one end of the dial block 40 to slide into the annular clamping groove 16 from the gap between the bottom of the cartridge 42 and the inner wall of the fixed cylinder 1. Furthermore, the ball 41 is in rolling connection with the inside of the arc-shaped raceway 17, enabling it to press the cartridge 42 without interfering with the rotation of the cartridge 42. At the same time, the filter port 34 on the movable block 36 slides directly below the through hole 25, connecting the through hole 25 and the drainage hole 23, thereby allowing air to be introduced into the annular air cavity 21.

[0025] Such as Figure 3 、 Figure 5 and Figure 7As shown, the on-off control device includes a contact rod 28. Inner cavities 29 are provided near the top and bottom edges inside the contact rod 28. The two inner cavities 29 inside the same contact rod 28 communicate with each other. A plurality of through holes 30 penetrating to the outside are equidistantly arranged along the circumferential direction on the inner walls of the two inner cavities 29. An adjustment cavity 27 is provided inside the annular ring 18. The contact rod 28 is located inside the adjustment cavity 27. The bottom of the contact rod 28 penetrates to the lower side of the annular ring 18. An annular plate 31 is fixed on the outer surface of the contact rod 28. The annular plate 31 is located inside the adjustment cavity 27. A return spring 32 is fixed on the top of the annular plate 31. The top of the return spring 32 is fixed on the inner top surface of the adjustment cavity 27. A plurality of air distribution holes 26 are equidistantly arranged along the circumferential direction on the inner bottom surface and one inclined surface inside the trapezoidal groove 15. One end of each of the plurality of air distribution holes 26 corresponds to and communicates with the top of the adjustment cavity 27. The top of the contact rod 28 correspondingly slides through to one end of the air distribution hole 26. The bottom of the contact rod 28 is located on one side of the arc-shaped protrusion 43.

[0026] The achieved effect is that when the barrel 42 rotates, when the bottom of the contact rod 28 slides to one side of the arc-shaped protrusion 43, as the barrel 42 rotates, the arc-shaped protrusion 43 will lift the contact rod 28 upward, so that the through hole 30 at the top of the contact rod 28 communicates with the air distribution hole 26, thereby intermittently sending the gas inside the annular air cavity 21 into the air distribution hole 26, and then flowing into the inner bottom surface of the barrel 42 through the air distribution hole 26.

[0027] Working principle: When using this device, first load the hematite fragments into the interior of the cartridge 42. The hematite fragments will generate their own weight inside the cartridge 42, thereby pressing the cartridge 42 downward and causing it to slide inside the fixed cylinder 1. As the hematite fragments inside the cartridge 42 increase, when the first grid opening 12 on the cartridge 42 slides to correspond to the second grid opening 14 on the fixed cylinder 1, water can be discharged into the interior of the cartridge 42 through the second grid opening 14 and the first grid opening 12. At this time, the weight of the cartridge 42 will further increase, causing it to continue to slide downward. When the outer surface of the bottom of the cartridge 42 fits against the dial 40, it will push the dial 40 towards the inner wall of the fixed cylinder 1, causing one end of the dial 40 to slide into the annular card slot 16 from the gap between the bottom of the cartridge 42 and the inner wall of the fixed cylinder 1. Furthermore, the ball 41 is in rolling connection inside the arc-shaped raceway 17, enabling it to press the cartridge 42 while not interfering with the rotation of the cartridge 42. At the same time, the filter opening 34 on the movable block 36 slides to directly below the through hole 25, causing the through hole 25 to communicate with the drainage hole 23, thereby allowing air to be introduced into the interior of the annular air chamber 21. At the same time, under the action of the pressing and positioning assembly, the friction between the friction disk 20 and the friction plate 33 can be ensured to be stably and firmly adhered. Then, the motor 19 drives the friction disk 20 to rotate. Since the friction disk 20 and the friction plate 33 are in frictional contact with each other, the cartridge 42 can be driven to rotate. When the cartridge 42 rotates, when the bottom of the contact rod 28 slides to one side of the arc-shaped protrusion 43, as the cartridge 42 rotates, the arc-shaped protrusion 43 will lift the contact rod 28 upward, causing the through hole 30 located at the top of the contact rod 28 to communicate with the air distribution hole 26, thereby intermittently sending the gas inside the annular air chamber 21 into the air distribution hole 26 and then flowing into the inner bottom surface of the cartridge 42 through the air distribution hole 26. The generated bubbles can rise from the bottom of the cartridge 42 and impact the hematite fragments during the rising process, thereby removing the impurities on the outer surface of the hematite fragments and mixing them into the water.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
