Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of magnetic separators, and particularly relates to a slag magnetic separator. Background Technique
[0002] Slag, also known as molten slag, is a melt that floats on the surface of liquid substances such as metals during pyrometallurgical processes. Its composition is mainly oxides (silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide), often contains sulfides and entangles a small amount of metals. After the slag is crushed, the iron substances inside need to be separated. To separate the iron substances from other substances in the slag, a slag magnetic separator is required. The slag magnetic separator is suitable for separating substances with magnetic differences.
[0003] In the utility model patent with the publication number CN218502344U, a belt magnetic separator for separating iron substances from slag is disclosed, which includes a top plate, a material receiving box, two first support columns, two second support columns, and two third support columns. The two first support columns, second support columns, and third support columns are respectively fixedly arranged on both sides and the midpoint of the lower end surface of the top plate. In this utility model, by installing a scraping and dividing plate to level and divide the crushed slag, the crushed slag is evenly and thinner dispersed on the conveyor belt, enhancing the separation of iron substances in the crushed slag. At the same time, there are two magnetic separation mechanisms and two conveyor belts to ensure the maximum separation of iron-containing substances in the crushed slag. There is a vibration motor at the lower end of the magnetic separator cooperating with a baffle to vibrate the crushed slag while preventing the crushed slag from scattering, achieving more thorough separation. The frequency conversion motor can adjust the conveyor belt speed, realizing the separation of iron substances in the crushed slag as much as possible, with better iron removal effect, and simple operation and convenient use.
[0004] However, in the above-mentioned utility model, there is no function for crushing the slag, and it cannot ensure that all the input slag is particles of the target size. During the separation process, due to the too large particles, the particles with high iron content cannot be adsorbed and separated, resulting in the iron resources continuing to be conveyed into the slag box, so that the iron resources cannot be fully separated, causing waste of iron resources.

[0023] As Figures 1-4 shown, a slag magnetic separator includes a bracket 6, a hopper 10, a feeder 34 and a self-unloading electromagnet 32. The feeder 34 is installed on the bracket 6, and the self-unloading electromagnet 32 is installed on the bracket 6. The self-unloading electromagnet 32 is located above the feeder 34. The feeder 34 is inclined, and the hopper 10 is installed at the lower end of the feeder 34.
[0024] A crushing barrel 11 is installed at the top of the hopper 10. A filter screen 30 is installed at the bottom of the crushing barrel 11. The size of the holes in the filter screen 30 can be determined according to the specific required particle size. A material receiving port is installed at the top of the crushing barrel 11. A first mounting frame 12 is installed on the material receiving port. A first motor 13 is installed on the first mounting frame 12. A vertically arranged transmission shaft 17 is installed at the output end of the first motor 13. A rotating rod 20 perpendicular to the transmission shaft 17 is fixedly connected to the bottom of the transmission shaft 17. The rotating rod 20 can perform circular motion driven by the transmission shaft 17. A rolling roller 18 is rotatably connected to the rotating rod 20. Crushing cones are provided on the rolling roller 18, which can better crush the slag. A first gear 21 is installed at one end of the rolling roller 18 close to the transmission shaft 17. A second gear 19 meshing with the first gear 21 is installed on the transmission shaft 17. When the transmission shaft 17 rotates, the first gear 21 rotates following the transmission shaft 17, and the first gear 21 drives the second gear 19 to rotate, thereby driving the rolling roller 18 to rotate. The rolling roller 18 rotates relative to the rotating rod 20 and rolls on the filter screen 30 to crush the slag on the filter screen 30.
[0025] A protective cover 15 is installed on the transmission shaft 17. The first gear 21 and the second gear 19 are located inside the protective cover 15. The protective cover 15 can protect the normal transmission between the first gear 21 and the second gear 19, preventing the slag put in from getting stuck between the first gear 21 and the second gear 19 and affecting the normal operation of the device.
[0026] An electric slide rail 31 is fixedly connected to the side wall of the transmission shaft 17. A pushing frame 14 is installed on the electric slide rail 31. The pushing frame 14 is a square frame. Guide rails 16 are provided on the protective cover 15. The pushing frame 14 is slidably connected to the guide rails 16 in the vertical direction. The pushing frame 14 can push the slag accumulated on the surface of the filter screen 30, making the slag evenly distributed on the filter screen 30, enabling better crushing of the filter residue, and allowing the particles that meet the size standard to pass through the filter screen 30 faster, improving the filtering efficiency of the filter screen 30.
[0027] The feeder 34 includes a second motor 2 and a first conveyor roller 4. The second motor 2 is connected to the bracket 6 through a second mounting bracket 3. The first conveyor roller 4 is arranged at the higher end of the feeder 34. The first conveyor roller 4 is rotatably connected to the bracket 6. A first pulley is installed at the output end of the second motor 2. The first conveyor roller 4 is provided with a second pulley that cooperates with the first pulley. The first pulley and the second pulley are connected by a first belt. The second motor 2 drives the first pulley, and the first pulley drives the second pulley to rotate through the first belt, thereby driving the first conveyor roller 4 to rotate. A second conveyor roller 9 is arranged at the lower end of the feeder 34. The second conveyor roller 9 is rotatably connected to the bracket 6. The first conveyor roller 4 and the second conveyor roller 9 are connected by a first conveyor belt 1. The first conveyor roller 4 drives the first conveyor belt 1 to rotate. The lower end of the first conveyor belt 1 is below the hopper 10, and the slag coming down from the hopper 10 can directly fall onto the first conveyor belt 1 for conveyance.
[0028] The self-unloading iron remover 32 includes a support frame 35. An iron remover body is arranged in the middle of the iron remover frame 28, including the support frame 35. A lifting ring 33 is provided on the support frame 35. The lifting ring 33 is connected to the iron remover frame 28 through a rope. A third mounting bracket 23 is installed on the iron remover frame 28. A third motor 29 is installed on the third mounting bracket 23. The third motor 29 is located above the iron remover frame 28. A third pulley is installed at the output end of the third motor 29. A third conveyor roller 24 and a fourth conveyor roller 27 are rotatably connected to the iron remover frame 28. A fourth pulley that cooperates with the third pulley is installed at one end of the third conveyor roller 24. The third pulley and the fourth pulley are connected by a second belt. The third conveyor roller 24 and the fourth conveyor roller 27 are connected by a second conveyor belt 22. The third motor 29 drives the second belt to rotate through the third pulley, the fourth pulley, the third conveyor roller 27 and the fourth conveyor roller 24. When the slag on the first conveyor belt 1 reaches below the self-unloading iron remover 32, the iron in the slag will be adsorbed by the self-unloading iron remover 32 onto the second conveyor belt 22. When the position of the second conveyor belt 22 adsorbed with iron turns to one end of the self-unloading iron remover 32, the iron will no longer be adsorbed by the magnetic force or the magnetic force received is too small, then it will fall off.
[0029] A scraper 25 that cooperates with the second conveyor belt 22 is installed on the iron remover frame 28. The scraper 25 is slidably connected to the conveyor belt. The scraper 25 is inclined. One end of the scraper 25 connected to the second conveyor belt 22 is higher, and the end of the scraper 25 away from the second conveyor belt 22 is lower. When the iron adsorbed on the second conveyor belt 22 moves along the second conveyor belt 22, it may occur that the iron adheres to the second conveyor belt 22 or continues to be adsorbed on the second conveyor belt 22 due to magnetic force. The scraper 25 can scrape off the iron on the second conveyor belt 22 when the second conveyor belt 22 reaches the position of the scraper 25; A baffle 26 is installed on the iron remover frame 28. The bottom of the baffle 26 is lower than the bottom of the scraper 25. A slag discharging chute 8 is installed on the bracket 6. The slag discharging chute 8 is located below the scraper 25. When the iron adsorbed on the second conveyor belt 22 is conveyed to one end of the self-unloading iron remover 32, it may be thrown out due to insufficient magnetic force, resulting in the iron not falling correctly into the slag discharging chute 8, causing the iron to fly randomly, polluting the working environment and wasting resources.
[0030] A iron collecting box 7 is provided below the slag discharging chute 8. The iron collecting box 7 is used to collect the iron in the slag that slides down from the slag discharging chute 8. A slag box 5 is provided below the first conveyor roller 4. The slag box 5 is used to collect the slag that has been iron-removed and falls from the first belt.
[0031] In summary, in actual use, the slag is placed into the crushing bucket 11. After being crushed by the rolling roller 18 and filtered by the filter screen 30, the slag is crushed into particles that meet the particle size requirements. The slag falls through the hopper 10 onto the first conveyor belt 1. The filter residue is transported along the first conveyor belt 1 and passes under the self-unloading iron remover 32. After being screened by the self-unloading iron remover 32, the slag without iron continues to be conveyed and falls into the slag box 5 at the end away from the hopper 10. The iron is adsorbed onto the second conveyor belt 22 of the self-unloading iron remover 32 for conveyance, and then falls into the iron collecting box 7 through the iron discharging chute.
[0032] The specific embodiments of the present invention described above do not constitute a limitation to the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention shall be included in the protection scope of the claims of the present invention.
