Description

Technical Field

[0001] This invention relates to the field of screening and processing equipment technology, and more specifically to a screening and processing equipment and method for raw materials used in the production of aluminum-calcium composite deoxidizer. Background Technology

[0002] Aluminum-calcium composite deoxidizer is a commonly used high-efficiency deoxidizing material in steelmaking, composed of aluminum and calcium elements in a specific ratio. Its core function is to rapidly reduce the oxygen content in molten steel, decrease oxide inclusions, and improve the purity and mechanical properties of the steel through the synergistic effect of aluminum's high deoxidation capacity and calcium's modifying effect. Aluminum provides strong reducing properties, while calcium optimizes the morphology of inclusions and prevents nozzle clogging. This deoxidizer is suitable for the production of high-strength steel, alloy steel, and stainless steel, and has advantages such as rapid reaction, high deoxidation efficiency, and controllable cost. It is a key additive for improving steel quality in modern continuous casting processes. The production of aluminum-calcium composite deoxidizer requires a screening process.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The raw material screening and processing device and method for the production of aluminum-calcium composite deoxidizer involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Reference Figure 1 and Figure 6This invention provides a raw material screening and processing device and method for the production of aluminum-calcium composite deoxidizer, including a main body 1. A feed inlet 4 is located at the top of the main body 1. A first screen 9 is located below the feed inlet 4 to remove large particles and incompletely broken clumps. A mounting frame 10 is fixedly connected to the first screen 9 and to the main body 1. A second screen 11 is located below the first screen 9 to separate fine powder, ensuring uniform particle size and improving deoxidation reaction efficiency. The first screen 9 and the second screen 11 are inclined, with the end closer to the feed inlet 4 higher and the end further away from the feed inlet 4 lower. The second screen 11 is fixedly connected to the mounting frame 10. A tapping mechanism is provided between the first screen 9 and the second screen 11. The mechanism prevents the first screen 9 and the mounting frame 10 from clogging. The beating mechanism includes a first rotating shaft 30, which is rotatably connected to the mounting frame 10. A second connecting rod 31 is fixedly connected to the first rotating shaft 30. A sliding sleeve 32 is rotatably connected to the end of the second connecting rod 31 away from the first rotating shaft 30. A beating plate 33 is movably sleeved on the sliding sleeve 32. One end of the beating plate 33 is rotatably connected to the mounting frame 10. The rotation of the first rotating shaft 30 drives the second connecting rod 31, which is fixedly connected to it, to rotate. The rotation of the second connecting rod 31 drives the beating plate 33 to reciprocate and beat the first screen 9 and the second screen 11 through the sliding sleeve 32, so as to prevent the screen from clogging during screening, improve screening efficiency, make the raw materials more uniform, and improve the quality of subsequent production. Reference Figure 1 The lower ends of the first screen 9 and the second screen 11 are respectively provided with the first discharge port 2 and the second discharge port 3. The first discharge port 2 and the second discharge port 3 are located on the side wall of the main body 1 of the device. A collection box 5 is provided below the mounting frame 10 for collecting finer raw material powder. The bottom end of the mounting frame 10 is provided with a pulley 12, and the pulley 12 is slidably connected to a fixed frame 13. The fixed frame 13 is fixedly connected to the main body 1 of the device. The slidable connection between the pulley 12 and the fixed frame 13 makes the mounting frame 10 more stable when moving. Reference Figure 1 , Figure 2 and Figure 5 The feed inlet 4 is equipped with a crushing rod 6 to crush the raw material. The bottom of the feed inlet 4 is equipped with a guide plate 7 to guide the raw material. The guide plate 7 is fixedly connected to the main body 1 of the device. A conveying rod 8 is provided below the crushing rod 6. The conveying rod 8 is rotatably connected to the feed inlet 4. A spiral blade 34 is fixedly connected to the side wall of the conveying rod 8. The conveying rod 8 and the spiral blade 34 are used to convey the raw material. Reference Figure 1 and Figure 3The main body 1 of the device is fixedly connected to a motor 14. The output end of the motor 14 is provided with an output rod 15. The output rod 15 is rotatably connected to the mounting frame 10. The end of the output rod 15 away from the motor 14 is fixedly connected to a turntable 16. The end of the turntable 16 away from the output rod 15 is rotatably connected to a first connecting rod 17. The end of the first connecting rod 17 away from the turntable 16 is rotatably connected to the mounting frame 10. When screening the raw materials, the motor 14 is started to drive the output rod 15 at the output end of the motor 14 to rotate. The rotation of the output rod 15 drives the turntable 16 fixedly connected to it to rotate. The rotation of the turntable 16 drives the mounting frame 10 to move back and forth through the first connecting rod 17. The back and forth movement of the mounting frame 10 drives the first screen 9 and the second screen 11 to vibrate, thus screening the raw materials. Because the first screen 9 and the mounting frame 10 are inclined, the raw materials on the first screen 9 and the mounting frame 10 will eventually flow into the first discharge port 2 and the second discharge port 3. Reference Figure 4 and Figure 7 The output rod 15 is driven by a first belt 18. The end of the first belt 18 furthest from the output rod 15 is driven by a first rotating rod 19. The first rotating rod 19 is rotatably connected to the main body 1 of the device. The first rotating rod 19 is fixedly connected to a first bevel gear 20, which meshes with a second bevel gear 21. The second bevel gear 21 is fixedly connected to a sleeve shaft 22, which is rotatably connected to the main body 1 of the device. The sleeve shaft 22 is slidably connected to a second rotating rod 23. A snap-fit ​​plate 24 is fixedly connected to the side wall of the second rotating rod 23, snapping against the sleeve shaft 22. The end of the second rotating rod 23 furthest from the sleeve shaft 22 is fixedly connected to a third bevel gear 25, which meshes with a fourth bevel gear 26. The fourth bevel gear 26 is fixedly connected to a third rotating rod 27, which is rotatably connected to the mounting bracket 10. The end away from the sleeve shaft 22 is rotatably connected to the mounting bracket 10, so that the third bevel gear 25 and the fourth bevel gear 26 can maintain meshing connection when the mounting bracket 10 moves. The output rod 15 rotates and drives the first rotating rod 19 to rotate through the first belt 18. The rotation of the first rotating rod 19 drives the first bevel gear 20 fixedly connected to it to rotate. The rotation of the first bevel gear 20 drives the second bevel gear 21 meshing with it to rotate. The rotation of the second bevel gear 21 drives the sleeve shaft 22 fixedly connected to it to rotate. The rotation of the sleeve shaft 22 drives the second rotating rod 23 to rotate through the snap-fit ​​plate 24 that snaps with it. The rotation of the second rotating rod 23 drives the third bevel gear 25 fixedly connected to it to rotate. The rotation of the third bevel gear 25 drives the fourth bevel gear 26 meshing with it to rotate. The rotation of the fourth bevel gear 26 drives the third rotating rod 27 fixedly connected to it to rotate. The end of the third rotating rod 27 away from the fourth bevel gear 26 is fixedly connected to the first gear 28. The first gear 28 is meshed with the second gear 29. The second gear 29 is fixedly connected to the first rotating shaft 30. The diameter of the second gear 29 is larger than that of the first gear 28. The rotation of the third rotating rod 27 drives the first gear 28 fixedly connected to it to rotate. The rotation of the first gear 28 drives the second gear 29 meshing with it to rotate. The rotation of the second gear 29 drives the first rotating shaft 30 fixedly connected to it to rotate. Since the diameter of the second gear 29 is larger than that of the first gear 28, the rotation speed of the second gear 29 is lower than that of the first gear 28, so as to avoid the beating speed of the beating mechanism being too fast, which would damage the first screen 9 and the second screen 11. Reference Figure 1 , Figure 4 and Figure 5 The output rod 15 is driven by a second belt 35. The end of the second belt 35 away from the output rod 15 is driven by a second rotating shaft 36. The second rotating shaft 36 is rotatably connected to the main body 1 and the feed inlet 4. The end of the second rotating shaft 36 away from the second belt 35 is fixedly connected to a fifth bevel gear 37. The fifth bevel gear 37 meshes with a sixth bevel gear 38. The sixth bevel gear 38 is fixedly connected to the conveying rod 8. The second rotating shaft 36 is driven by a third belt 39. The rotation of the output rod 15 drives the second rotating shaft 36 to rotate through the second belt 35. The rotation of the second rotating shaft 36 drives the crushing rod 6 to rotate through the third belt 39 to crush the raw material. The rotation of the second rotating shaft 36 drives the fifth bevel gear 37 fixedly connected to it to rotate. The rotation of the fifth bevel gear 37 drives the sixth bevel gear 38 meshing with it to rotate. The rotation of the sixth bevel gear 38 drives the conveying rod 8 fixedly connected to it to rotate. The rotation of the conveying rod 8 drives the spiral blades 34 fixedly connected to it to continuously and evenly convey the raw material to the top of the first screen 9.

[0026] Working principle of this invention: Firstly, when screening the raw materials, the starting motor 14 drives the output rod 15 located at the output end of the motor 14 to rotate. The rotation of the output rod 15 drives the second rotating shaft 36 to rotate via the second belt 35. The rotation of the second rotating shaft 36 drives the crushing rod 6 to rotate via the third belt 39, thus crushing the raw materials. The rotation of the second rotating shaft 36 drives the fifth bevel gear 37 fixedly connected to it to rotate. The rotation of the fifth bevel gear 37 drives the sixth bevel gear 38 meshing with it to rotate. The rotation of the sixth bevel gear 38 drives the conveying rod 8 fixedly connected to it to rotate. The rotation of the conveying rod 8 drives the spiral blade 34 fixedly connected to it to rotate, continuously and evenly conveying the raw materials to the top of the first screen 9. The rotation of the output rod 15 drives the turntable 16 fixedly connected to it to rotate. The rotation of the turntable 16 drives the mounting frame 10 to move back and forth via the first connecting rod 17. The back and forth movement of the mounting frame 10 drives the first screen 9 and the second screen 11 to vibrate, thus screening the raw materials. Because the first screen 9 and the mounting frame 10 are inclined, the raw materials on the first screen 9 and the mounting frame 10 will eventually flow into the first discharge port 2 and the second discharge port 3.

[0027] Secondly: The rotation of the output rod 15 drives the first rotating rod 19 to rotate via the first belt 18. The rotation of the first rotating rod 19 drives the first bevel gear 20 fixedly connected to it to rotate. The rotation of the first bevel gear 20 drives the second bevel gear 21 meshing with it to rotate. The rotation of the second bevel gear 21 drives the sleeve shaft 22 fixedly connected to it to rotate. The rotation of the sleeve shaft 22 drives the second rotating rod 23 to rotate via the snap-fit ​​plate 24 that is snapped with it. The rotation of the second rotating rod 23 drives the third bevel gear 25 fixedly connected to it to rotate. The rotation of the third bevel gear 25 drives the fourth bevel gear 26 meshing with it to rotate. The rotation of the fourth bevel gear 26 drives the third rotating rod 27 fixedly connected to it to rotate. The rotation of the third rotating rod 27 drives the first gear 28 fixedly connected to it to rotate. The rotation of the first gear 28 drives the second gear 29 meshing with it to rotate. The rotation of the second gear 29 drives the first rotating shaft 30 fixedly connected to it to rotate.

[0028] Finally: The rotation of the first rotating shaft 30 drives the second connecting rod 31, which is fixedly connected to it, to rotate. The rotation of the second connecting rod 31 drives the slapping plate 33 to reciprocate and slap the first screen 9 and the second screen 11 through the sliding sleeve 32 connected to it, so as to prevent the screen from clogging during screening, improve screening efficiency, make the raw materials more uniform, and improve the quality of subsequent production.

Because the first screen (9) and the mounting frame (10) are inclined, the raw material on the first screen (9) and the mounting frame (10) will eventually flow into the first discharge port (2) and the second discharge port (3). Secondly: the output rod (15) rotates through the first belt (18) to drive the first rotating rod (19) to rotate. The rotation of the first rotating rod (19) drives the first bevel gear (20) fixedly connected to it to rotate. The rotation of the first bevel gear (20) drives the second bevel gear (21) meshing with it to rotate. The rotation of the second bevel gear (21) drives the sleeve shaft (22) fixedly connected to it to rotate. The rotation of the sleeve shaft (22) drives the second rotating rod (23) to rotate through the snap plate (24) snapped with it. The rotation of the second rotating rod (23) drives the third bevel gear (25) fixedly connected to it to rotate. The rotation of the third bevel gear (25) drives the fourth bevel gear (26) meshing with it to rotate. The rotation of the fourth bevel gear (26) drives the third rotating rod (27) fixedly connected to it to rotate. The rotation of the third rotating rod (27) drives the first gear (28) fixedly connected to it to rotate. The rotation of the first gear (28) drives the second gear (29) meshing with it to rotate. The rotation of the second gear (29) drives the first rotating shaft (30) fixedly connected to it to rotate. Finally: The rotation of the first rotating shaft (30) drives the rotation of the second connecting rod (31) fixedly connected to it. The rotation of the second connecting rod (31) drives the slapping plate (33) to reciprocate and slap the first screen (9) and the second screen (11) through the sliding sleeve (32) connected to it, so as to prevent the screen from clogging easily during screening, improve screening efficiency, make the raw materials more uniform, and improve the quality of subsequent production.
