Description

Technical Field

[0001] This utility model relates to the field of impurity removal technology for iron concentrate, and more specifically, to an impurity removal device for recovering iron concentrate from metallurgical waste slag by magnetic separation. Background Technology

[0002] The magnetic separation and impurity removal device for metallurgical waste slag uses a magnetic field to separate ferromagnetic substances and non-ferromagnetic impurities in metallurgical waste slag. Ferromagnetic particles in iron concentrate are adsorbed onto the magnetic components of the impurity removal device, while non-magnetic impurities are removed, thereby improving the purity of iron concentrate and providing high-quality raw materials for subsequent smelting and other processes.

[0003] However, recovering iron concentrate from metallurgical waste slag presents certain challenges in practical applications. Existing magnetic separation methods for recovering iron concentrate encounter the following problems: When magnetically separating large quantities of metallurgical waste slag, the suspended magnetic separation results in a small contact area with the iron concentrate, leading to limited magnetic field lines capturing the iron concentrate for an ineffective period. Simultaneously, impurities cannot be removed in bulk, impacting magnetic separation efficiency. Therefore, a purification device for recovering iron concentrate from metallurgical waste slag using magnetic separation is needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a device for removing impurities from metallurgical waste slag through magnetic separation to recover iron concentrate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing impurities from metallurgical waste slag through magnetic separation and recovery of iron concentrate, comprising a motor housing, a motor fixedly mounted inside the motor housing, a large gear fixedly mounted at the output end of the motor, a transmission mechanism on one side of the large gear, a permanent magnet I with a triangular cross-sectional area on one side inside the transmission mechanism, a permanent magnet II with a V-shaped cross-sectional area on the other side inside the transmission mechanism, mounting boxes fixedly mounted on both sides of the permanent magnet I and permanent magnet II, a recovery mechanism on one side of the mounting box, a vibrating screen on the top of the mounting box, and a support mechanism on one side of the motor housing.

[0006] As a further description of the above technical solution: the transmission mechanism includes a small gear that meshes with the top of the large gear, a transmission rod is fixedly provided inside the small gear, a mounting box is rotatably provided on one side of the transmission rod, a roller is fixedly provided on the surface of the transmission rod, a transmission belt is sleeved on the outside of the roller, and a transverse raised surface is fixedly provided on the surface of the transmission belt.

[0007] As a further description of the above technical solution: the transmission belt is equipped with a plurality of large-range electromagnetic chucks, both ends of which are fixedly connected to the mounting box. One of the large-range electromagnetic chucks is provided with a steering roller on one side, and the bottom of the other large-range electromagnetic chuck is provided with a transmission roller one and a transmission roller two, with the transmission roller one located on one side of the transmission roller two.

[0008] As a further description of the above technical solution: the bottom of the first discharge port of the vibrating screen is provided with a guide tube, the bottom of the inner wall of the guide tube is provided with multiple baffles, and the bottom of the second discharge port of the vibrating screen is provided with a waste collection box.

[0009] As a further description of the above technical solution: the recycling mechanism includes a fixed rod, both ends of which are fixedly provided with mounting boxes, and two symmetrically distributed permanent magnet sleeves are fixedly provided on the surface of the fixed rod, and scraper sleeves are sleeved on the outer sides of the two permanent magnet sleeves.

[0010] As a further description of the above technical solution: an electric telescopic rod is fixedly provided on one side of each of the two scraper cylinders, and the two electric telescopic rods are respectively fixedly provided inside the mounting box.

[0011] As a further description of the above technical solution: the support mechanism includes a base, a motor housing is provided on one side of the base, the top of the base is fixedly connected to the mounting box, and multiple load-bearing plates are welded to the bottom of the base.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By setting up a transmission mechanism, compared with the existing technology, the horizontal ridges on the surface of the transmission belt can prevent the iron concentrate from being lost during movement, while the magnetic force generated by the electromagnetic chuck will penetrate the transmission belt and accurately adsorb the iron concentrate, making it move with the transmission belt, while non-magnetic or weakly magnetic waste slag rolls off under gravity, and the steering roller controls the iron concentrate to fall in a fixed position. The whole mechanism is conducive to improving the impurity removal efficiency of iron concentrate during the impurity removal process.

[0014] 2. By setting up permanent magnet one and permanent magnet two, compared with the existing technology, permanent magnet one uses its own stable magnetic field to adsorb the scattered iron concentrate powder during the process of the waste slag falling from the guide tube to the transmission belt, effectively reducing the loss of iron concentrate powder and greatly reducing the loss of iron concentrate powder in the initial stage. When the transmission belt moves the iron concentrate powder to the edge of the electromagnetic chuck, the magnetic force of the electromagnetic chuck gradually weakens. The unique magnetic field distribution of permanent magnet two can seamlessly replace the magnetic force of the electromagnetic chuck, so that the iron concentrate powder is stably transported to the subsequent recycling stage, ensuring the integrity of the iron concentrate powder during the transportation process and improving the continuity and reliability of the entire recycling process.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1-5 The device shown is a metallurgical waste magnetic separation and iron concentrate recovery device, including a motor housing 1, a motor 2 fixedly installed inside the motor housing 1, a large gear 3 fixedly installed at the output end of the motor 2, a transmission mechanism on one side of the large gear 3, a permanent magnet 4 with a triangular cross-sectional area on one side inside the transmission mechanism, a permanent magnet 5 with a V-shaped cross-sectional area on the other side inside the transmission mechanism, mounting boxes 6 fixedly installed on both sides of the permanent magnet 4 and the permanent magnet 5, a recovery mechanism on one side of the mounting box 6, a vibrating screen 7 on the top of the mounting box 6, and a support mechanism on one side of the motor housing 1.

[0023] In some embodiments, according to Figure 5As shown, the transmission mechanism includes a small gear 8 that meshes with the top of the large gear 3. A transmission rod 9 is fixedly installed inside the small gear 8. A mounting box 6 is rotatably installed on one side of the transmission rod 9. A roller 10 is fixedly installed on the surface of the transmission rod 9. A transmission belt 11 is sleeved on the outside of the roller 10. A horizontal ribbed protrusion 12 is fixedly installed on the surface of the transmission belt 11. The horizontal ribbed protrusion 12 can effectively collect iron concentrate on the transmission belt 11 and reduce the loss of iron concentrate.

[0024] In some embodiments, according to Figure 5 As shown, multiple large-range electromagnetic chucks 13 are fitted inside the transmission belt 11. Both ends of the multiple large-range electromagnetic chucks 13 are fixedly connected to the mounting box 6. One of the large-range electromagnetic chucks 13 has a steering roller 14 on one side. One of the large-range electromagnetic chucks 13 has a transmission roller 15 and a transmission roller 2 16 at the bottom. The transmission roller 15 is located on one side of the transmission roller 2 16. The multiple large-range electromagnetic chucks 13 are combined into a whole and are in close contact with the transmission belt 11, which reduces the gap between the iron concentrate and the electromagnetic chucks 13 and allows the iron concentrate to be subjected to greater magnetic force.

[0025] In some embodiments, according to Figure 3 and 4 As shown, the bottom of the first discharge port of the vibrating screen 7 is provided with a guide tube 17, and the bottom of the inner wall of the guide tube 17 is provided with multiple baffles 18. The bottom of the second discharge port of the vibrating screen 7 is provided with a waste collection box 19. The baffles 18 can allow the waste residue to be evenly spread on the transmission belt 11, which improves the magnetic adsorption efficiency.

[0026] In some embodiments, according to Figure 2 and 3 As shown, the recycling mechanism includes a fixed rod 20, with mounting boxes 6 fixed at both ends of the fixed rod 20. Two symmetrically distributed permanent magnet sleeves 21 are fixed on the surface of the fixed rod 20. Scraper cylinders 22 are sleeved on the outer side of the two permanent magnet sleeves 21. Electric telescopic rods 23 are fixed on one side of the surface of the two scraper cylinders 22. The two electric telescopic rods 23 are respectively fixed inside the mounting box 6. A receiving box 24 is provided at the bottom of the fixed rod 20. The receiving box 24 is fixedly connected to the bottom of the mounting box 6. When the transmission belt 11 moves the iron concentrate to above the fixed rod 20, the distance between the permanent magnet sleeves 21 and the transmission belt 11 is very small, which can efficiently attract the iron concentrate adhering to the transmission belt 11.

[0027] In some embodiments, according to Figure 1 and 3 As shown, the support mechanism includes a base 25, a motor housing 1 on one side of the base 25, a fixed connection between the top of the base 25 and the mounting box 6, and multiple load-bearing plates 26 welded to the bottom of the base 25. The height of the load-bearing plates 26 increases in a stepped manner, so that the transmission belt 11 of this utility model is in an inclined state, allowing the waste residue that is not affected by magnetic force and moves with the transmission belt to roll off the transmission belt due to gravity.

[0028] The working principle of this utility model is as follows: First, start the motor 2 and electromagnetic chuck 13 to make the transmission belt 11 move. Then, start the vibrating screen 7 and pour the metallurgical waste into the vibrating screen 7. As the waste passes through the vibrating screen 7, the particle size of the waste becomes finer and falls into the guide tube 17 through the discharge port 1. At the same time, the remaining waste falls into the waste collection box 19 through the discharge port 2. The screened waste contains a large amount of iron concentrate. In order to spread the waste evenly on the transmission belt 11, the waste passes through the guide tube 17. The waste residue is diverted by the partition 18. The surface of the transmission belt 11 is also designed with horizontal raised sections 12 to prevent iron concentrate from being lost due to insufficient friction. Furthermore, a triangular permanent magnet 4 is installed inside the transmission belt 11, below the guide tube 17, to prevent iron concentrate from being lost when exiting the guide tube 17. The magnetic force of multiple electromagnetic chucks 13 inside the transmission belt 11 passes through the belt and attracts the iron concentrate onto it, causing it to move along with the belt. Metallurgical waste slag that is non-magnetic or minimally affected by magnetic force will roll off the transmission belt 11 due to gravity. When the transmission belt 11 reaches the outermost edge of the electromagnetic chuck 13, the magnetic force of the electromagnetic chuck 13 gradually disappears. However, the iron concentrate remains stable on the transmission belt 11 due to the magnetic force of another V-shaped permanent magnet 5. When the iron concentrate on the transmission belt 11 moves to the steering roller 14, the magnetic force disappears, and the iron concentrate falls downwards under the influence of gravity, essentially perpendicular to the ground. To prevent the transmission belt 11 from falling, the magnetic force is reduced. There is residual iron concentrate on the conveyor belt 11. A permanent magnet sleeve 21 is also installed under the steering roller 14. When the iron concentrate moves to the position of the permanent magnet sleeve 21, the iron concentrate on the conveyor belt 11 is subjected to both gravity and magnetic force. The iron concentrate will be completely attracted to the permanent magnet sleeve 21. Then, the electric telescopic rod 23 is activated. The output end of the electric telescopic rod 23 is equipped with a scraper sleeve, which can scrape the iron concentrate off the permanent magnet sleeve 21. A sufficiently large collection box 24 is designed under the iron concentrate to ensure the recovery rate of the iron concentrate after impurity removal.
