However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0021] Embodiment 1: As Figures 1-4 shown, the present invention provides a technical solution: a slag fine powder iron removal device, including a device body 1, a hopper 9 is arranged on the top of the device body 1, a first fixed frame 2 is arranged on the top of the hopper 9, two first cylinders 3 are symmetrically arranged on both sides of the first fixed frame 2, the output end of the first cylinder 3 movably penetrates through the first fixed frame 2 and is connected with a connecting plate 4, four corners on one side of the connecting plate 4 are all provided with fastening bolts 5, a movable frame 6 is arranged on the other side of the connecting plate 4, a sieve box 7 is arranged inside the movable frame 6, and two ends of the top of the sieve box 7 are both provided with first pull rings 8.

[0022] In this embodiment, the connecting plate 4 is fixedly connected with the movable frame 6 through the fastening bolts 5 to improve the stability during sieving. By repeatedly extending and retracting the two first cylinders 3, the movable frame 6 is driven to swing left and right in the first fixed frame 2, so as to sieve the slag fine powder in the sieve box 7, and the larger lumps are retained in the sieve box 7. By grasping and lifting the first pull ring 8, the sieve box 7 can be taken out of the movable frame 6, so as to centrally process the sieved lumps, thereby preventing the iron removal device from being blocked, improving the quality of the iron removal work, improving the efficiency of the iron removal work, and meeting the actual use requirements.

[0023] Embodiment 2: As Figures 1-4As shown, brackets 10 are symmetrically arranged at both ends on one side of the device body 1. A conveying component is arranged between the two brackets 10. A fixing frame 11 is arranged at the top of the two brackets 10. Two second cylinders 12 are arranged at the top of the fixing frame 11. The output end of the second cylinder 12 movably penetrates through the fixing frame 11 and is connected to a scraper 13. The conveying component includes a driving roller 15. A motor 14 is arranged on one side of a single bracket 10. The output end of the motor 14 movably penetrates through the single bracket 10 and is connected to the driving roller 15. A driven roller 16 is arranged on one side of the device body 1. A magnetic belt 17 is sleeved on the outer sides of the driving roller 15 and the driven roller 16. A fine powder collection box 18 is inserted into the inner side of the device body 1. A handle 19 is arranged on the surface of the fine powder collection box 18. A second fixing frame 20 is arranged on one side of the device body 1. A scrap iron collection box 21 is inserted into the inner side of the second fixing frame 20. A second pull ring 22 is arranged on the surface of the scrap iron collection box 21. Four corners at the bottom of the device body 1 are all provided with feet 23. Anti-slip pads 24 are fixedly connected to the bottoms of the feet 23.

[0024] In this embodiment, by the telescopic movement of the two second cylinders 12, the scraper 13 can be driven to scrape the iron filings adsorbed on the magnetic belt 17, thereby preventing a large amount of iron filings from accumulating on the magnetic belt 17. At the same time, it is convenient to clean the magnetic belt 17, ensuring the cleanliness of the surface of the magnetic belt 17, so as to improve the iron removal efficiency, reduce the cleaning difficulty, and save labor and time costs. By driving the driving roller 15 to rotate by the motor 14, the magnetic belt 17 is driven to rotate synchronously on the outer sides of the driving roller 15 and the driven roller 16, so as to convey the slag fine powder and adsorb the iron filings in the slag fine powder at the same time, so as to achieve the purpose of iron removal. The fine powder collection box 18 can collect the slag fine powder after iron removal. By grasping and pulling the handle 19, the fine powder collection box 18 can be taken out of the device body 1 to centrally process the collected slag fine powder. The scrap iron collection box 21 can collect the scraped-off iron filings. By grasping and pulling the second pull ring 22, the scrap iron collection box 21 can be taken out of the second fixing frame 20 to centrally process the collected iron filings. By using the anti-slip pads 24 in cooperation with the feet 23, the friction force can be increased, thereby improving the stability of the device during operation and preventing the device from shaking or tipping over.

[0025] Working principle of this embodiment: During use, first pour the slag powder into the sieve box 7, and at the same time start two first cylinders 3. The two first cylinders 3 repeatedly extend and retract, driving the movable frame 6 to shake in the first fixed frame 2 to sieve the slag powder in the sieve box 7. Then, the sieved slag powder falls from the funnel 9 onto the magnetic belt 17. Start the motor 14 to drive the driving roller 15 to rotate, thereby driving the magnetic belt 17 to convey the slag powder and adsorb the iron filings in the slag powder. The slag powder slides into the fine powder collection box 18 from the position of the driven roller 16. At this time, start the second cylinder 12 to push the scraper 13 to scrape the iron filings adsorbed on the magnetic belt 17, so that they fall into the waste iron collection box 21. Finally, grasp and lift the first pull ring 8 to take out the sieve box 7 and centrally process the agglomerates remaining in the sieve box 7 after screening. At the same time, grasp and pull the handle 19 to take out the fine powder collection box 18 from the device body 1 and centrally process the slag powder after iron removal. Then grasp and pull the second pull ring 22 to take out the waste iron collection box 21 from the second fixed frame 20 and centrally process the collected iron filings, thus completing the use of the slag powder iron removal device.
