Description

Technical Field

[0002] A dry magnetic separator for iron concentrate powder is a device used to process dry magnetic minerals (such as iron ore), mainly used to further remove non-magnetic impurities from iron concentrate powder and improve the grade of iron concentrate powder. This device mainly utilizes the magnetic differences of different minerals for separation.

However, if a large amount of iron concentrate powder is fed at one time during magnetic separation, it is extremely easy to affect the magnetic separation efficiency. Moreover, when the ore is discharged from the magnetic separation mechanism after magnetic separation, the minerals after magnetic separation are likely to scatter, resulting in the minerals being unable to be collected in time. For this reason, we propose a dry magnetic separator for iron concentrate powder. Content of the Utility Model

[0017] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a dry magnetic separator for iron concentrate powder, including a separation box 1, a support leg 2 is fixedly installed on the separation box 1, a first discharge pipe 7 and a second discharge pipe 8 penetrate through the bottom of the separation box 1, a magnetic separation mechanism 3 for magnetic separation is arranged inside the separation box 1, a discharge mechanism 4 for discharging iron concentrate powder is arranged at a position corresponding to the magnetic separation mechanism 3 on the separation box 1, a vibration mechanism 5 for preventing the accumulation of iron concentrate powder is arranged on the discharge mechanism 4, and a scraping mechanism 6 for removing the materials adsorbed on the magnetic separation mechanism 3 is arranged on one side of the separation box 1.

[0018] Among them, by setting the magnetic separation mechanism 3, the iron concentrate powder can be further magnetically separated and screened. The iron concentrate powder to be screened is discharged through the discharge mechanism 4, which can ensure uniform discharge during discharging, so as to ensure that the iron concentrate powder can be fully magnetically separated. The set vibration mechanism 5 can prevent the iron concentrate powder from remaining above the discharge mechanism 4, and the set scraping mechanism 6 can scrape the minerals on the magnetic separation mechanism 3 step by step to prevent the minerals from being scraped off at one time and causing the minerals to splash everywhere. Subsequently, the materials after magnetic separation can be discharged through the first discharge pipe 7 and the second discharge pipe 8.

[0019] Please refer to Figure 1 , the magnetic separation mechanism 3 includes a bearing seat 9, a rotating shaft 10, a first support frame 11 and a first driving motor 12.

[0020] Among them, the iron concentrate powder to be magnetically separated is discharged to the outer surface of the magnetic separation barrel 13 through the discharge mechanism 4. Subsequently, the first driving motor 12 is started to operate, the first driving motor 12 drives the rotating shaft 10 and the magnetic separation barrel 13 to rotate, and then the minerals without magnetism can be screened. The non-magnetic minerals after screening can be discharged through the second discharge pipe 8.

[0021] Please refer to Figure 1 andFigure 2 The blanking mechanism 4 includes a second support frame 14, a third support frame 15, a storage frame 16 and a partition net 17. A second support frame 14 is fixedly installed on one side of the sorting box 1. A storage frame 16 is fixedly installed on the second support frame 14 through multiple groups of third support frames 15. One side of the storage frame 16 is attached to the outer wall of the magnetic separation barrel 13. A blanking port 18 is formed through one side of the storage frame 16. A partition net 17 is hinged to one side inside the storage frame 16.

[0022] Among them, the iron concentrate that needs magnetic separation is discharged into the interior of the storage frame 16 through the partition net 17. The setting of the partition net 17 can prevent the agglomerated iron concentrate from being unable to complete blanking. Subsequently, the iron concentrate can discharge the minerals to the outer surface of the magnetic separation barrel 13 through the blanking port 18.

The outer wall of the driving plate 24 is attached to the bottom of the partition net 17.

[0024] Among them, the set second driving motor 23 can drive the elliptical driving plate 24 to rotate. Subsequently, the rotating driving plate 24 can push the partition net 17 to move up and down continuously. Such a setting can make the agglomerated minerals on the partition net 17 collide and loosen and fall into the interior of the storage frame 16.

[0025] Light meals are also Figure 1 and Figure 2 The scraping mechanism 6 includes a second support rod 21, a second scraper 22, a second driving motor 23 and a driving plate 24. Multiple groups of first support rods 19 are fixedly installed on the top of the second support frame 14. A first scraper 20 attached to the outer wall of the magnetic separation barrel 13 is fixedly installed on one side of the first support rod 19. Multiple groups of second support rods 21 are fixedly installed on the top of the second support frame 14 and on one side of the first scraper 20. A second scraper 22 attached to the outer wall of the rain magnetic separation barrel 13 is fixedly installed on one side of the second support rod 21. The first scraper 20 and the second scraper 22 are arranged vertically and staggeredly.

[0026] Among them, the first scraper 20 and the second scraper 22 are arranged vertically and staggeredly. Such a setting can make there be gaps on both sides of the first scraper 20 and the second scraper 22, which can ensure sufficient scraping when scraping the magnetic minerals and can avoid the possibility of the scraped minerals splashing. The remaining small amount of minerals can be scraped and discharged through the blanking frame 16.

[0027] Please refer toFigure 1 and Figure 2 One end of the sorting box 1 and the bottom of the first support frame 11, as well as one side of the sorting box 1 and the bottom of the second support frame 14 are fixedly connected through a reinforcing plate 25. Baffles 26 are fixedly connected to both ends of the magnetic separation barrel 13. The setting of the reinforcing plate 25 can ensure that the first support frame 11 and the second support frame 14 are deformed, while the setting of the baffle 26 can prevent the minerals subjected to magnetic separation from leaking out through both sides of the magnetic separation barrel 13.

[0028] During use, first, the magnetic separation mechanism 3 can be set to further perform magnetic separation screening on iron concentrate powder, and the iron concentrate powder to be screened is fed through the feeding mechanism 4, so as to ensure uniform feeding during feeding, thereby ensuring that the iron concentrate powder can be fully magnetically separated. The vibration mechanism 5 provided can prevent the iron concentrate powder from remaining above the feeding mechanism 4, and the scraping mechanism 6 provided can scrape the minerals on the magnetic separation mechanism 3 step by step to prevent the minerals from splashing everywhere when being scraped off at one time. Subsequently, the materials after magnetic separation can be discharged through the first discharge pipe 7 and the second discharge pipe 8. The iron concentrate powder to be magnetically separated is discharged through the feeding mechanism 4 to the outer surface of the magnetic separation barrel 13. Then, the first driving motor 12 is started to operate, and the first driving motor 12 drives the rotating shaft 10 and the magnetic separation barrel 13 to rotate. Subsequently, the minerals without magnetism can be screened. The non-magnetic minerals after screening can be discharged through the second discharge pipe 8. The iron concentrate powder to be magnetically separated is discharged into the interior of the containing frame 16 through the partition net 17. The setting of the partition net 17 can prevent the agglomerated iron concentrate powder from being unable to complete feeding. Subsequently, the iron concentrate powder can discharge the minerals to the outer surface of the magnetic separation barrel 13 through the discharge port 18. The second driving motor 23 provided can drive the elliptical driving plate 24 to rotate. Then, the rotating driving plate 24 can push the partition net 17 to continuously move up and down. Such a setting can make the agglomerated minerals on the partition net 17 collide and become loose and fall into the interior of the containing frame 16. The first scraper 20 and the second scraper 22 are arranged alternately up and down. Such a setting can make there be gaps on both sides of the first scraper 20 and the second scraper 22, so that when scraping the minerals with magnetism, they can be scraped off sufficiently, and the possibility of the scraped-off minerals splashing everywhere can be avoided. The remaining small amount of minerals can be scraped off and discharged through the discharging frame 16.
