[0002] Steel slag is a byproduct of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, as well as salts formed by the reaction of these oxides with solvents. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle it in the factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements; the other is to use it as a raw material for manufacturing road construction materials, building materials or agricultural fertilizers.

[0003] For example, the patent with application number: 202121249966.0 discloses a steel slag processing device, including a crushing bin, a first roller, a mixing bin, a second roller, crushing teeth, a motor and a protective cover.

[0026] See also Figure 1-5 The utility model provides a steel slag processing device for improving the recovery rate of iron in steel slag, comprising a processing box 1, a feed port 11 is arranged on the processing box 1, a crusher 111 for crushing steel slag is installed in the feed port 11, a magnetic roller 12 with a strong magnet is installed in the processing box 1, the magnetic roller 12 is used to absorb the iron slag in the steel slag falling after crushing, and the iron slag in the steel slag is adsorbed on the magnetic roller 12 by the magnetic roller 12 with a strong magnet, so as to better collect the iron slag, and the processing box 1 is also installed with a separation plate 13 for scraping off the iron slag adsorbed on the surface of the magnetic roller 12, and a rotating roller 14 is installed on the upper end of the separation plate 13. A plurality of brushes 141 are arranged on the rotating roller 14, and the brushes 141 are in contact with the separation plate 13. The rotating roller 14 drives the brushes 141 to rotate to scrape the iron slag on the separation plate 13 away from the magnetic roller 12 to separate the iron slag. A driving device 15 for driving the magnetic roller 12 and the rotating roller 14 to rotate is also installed outside the processing box 1.

[0027] Please pay attention to Figure 1 , Figure 3The driving device 15 includes a first gear 151, a second gear 152 and a driving motor 153. The first gear 151 is fixedly connected to the magnetic roller 12 through an axis, and the second gear 152 is fixedly connected to the rotating roller 14 through an axis. The first gear 151 is meshed with the second gear 152. A support seat is installed outside the processing box 1, and the driving motor 153 is fixed on the support seat. The driving motor 153 is used to drive the first gear 151 to rotate, and the first gear 151 is driven to rotate by the output shaft of the driving motor 153. The first gear 151 drives the second gear 152 to rotate, thereby driving the magnetic roller 12 and the rotating roller 14 to rotate in opposite directions at the same time, so as to facilitate the separation of the iron slag on the magnetic roller 12.

[0028] Please pay attention to Figure 2 , Figure 4 , Figure 5 The separation plate 13 includes a scraper 131 and a scraper head 132. The scraper 131 is fixedly installed in the processing box 1. The scraper head 132 is detachably installed on the scraper 131 through a slot. The end of the scraper head 132 contacts the surface of the magnetic roller 12. The scraper head 132 contacts the surface of the magnetic roller 12, thereby separating the iron slag on the magnetic roller 12 when the magnetic roller 12 rotates. The detachable design of the scraper head 132 makes it easy to replace the scraper head 132 after it is worn out after long-term use, thereby reducing the use cost of the equipment.

[0029] Please pay attention to Figure 4-5 Bolts 133 are symmetrically installed on the scraper head 132. The bolts 133 pass through the scraper head 132 and are connected to the scraper plate 131 through threads. The scraper head 132 is strengthened and fixed by the bolts 133, so that the scraper head 132 and the scraper plate 131 are installed more stably, and the scraper head 132 is prevented from loosening and falling off.

[0030] Please pay attention to Figure 5 The end of the scraper head 132 that contacts the magnetic roller 12 is provided with an arc surface, and the arc surface fits the surface of the magnetic roller 12. Through this design, the scraper head 132 and the magnetic roller 12 are in closer contact, thereby improving the effect of separating the iron slag on the magnetic roller 12.

[0031] Please pay attention to Figure 2The scraper 131 is installed in the processing box 1 in an inclined state. A discharge port 18 is opened on the processing box 1 at the end of the scraper 131. The scraped iron slag is automatically rolled to the direction of the discharge port 18 by the inclined scraper 131. A collecting bin 181 is also installed outside the processing box 1 at the discharge port 18. The height of the outer baffle of the collecting bin 181 is not lower than the height of the discharge port 18. The separated iron slag is conveniently collected through the collecting bin 181. The baffle on the outer side of the collecting bin 181 has a shielding effect on the discharge port 18 to prevent the iron slag from splashing and falling from the discharge port 18 when the brush 141 scrapes the iron slag.

[0032] Please pay attention to Figure 2 A first guide plate 16 and a second guide plate 17 are also installed in the processing box 1. The first guide plate 16 is installed in an inclined state below the feed port 11, and the second guide plate 17 is installed below the end of the first guide plate 16. The inclination direction of the second guide plate 17 is opposite to that of the first guide plate 16. The magnetic roller 12 is located above the second guide plate 17. Through this design, the steel slag falling after crushing can be evenly moved around the magnetic roller 12, so that the magnetic roller 12 can better absorb the iron slag in the steel slag, thereby further improving the iron recovery rate.

[0033] The working principle of the first embodiment of the utility model is as follows:

[0034] When in use, the drive motor 153 is started, and the output shaft of the drive motor 153 rotates to drive the first gear 151 to rotate counterclockwise, thereby driving the magnetic roller 12 to rotate counterclockwise, and the end of the scraper head 132 has a scraping effect on the surface of the magnetic roller 12. The first gear 151 rotates counterclockwise and pushes the second gear 152 to rotate clockwise. The second gear 152 drives the rotating roller 14 to rotate clockwise, so that the brush 141 scrapes the scraper head 132, and the steel slag is put into the feed port 11. The crusher 111 crushes the steel slag, and the crushed steel slag passes through the first guide plate 16 and rolls It falls onto the second guide plate 17. When the steel slag passes through the second guide plate 17, the magnetic force of the magnetic roller 12 adsorbs the iron slag in the steel slag to the surface. Since the magnetic roller 12 is in a counterclockwise rotation state, the iron slag on the surface of the magnetic roller 12 is scraped and accumulated to the end of the scraper head 132. The rotating roller 14 rotates clockwise to drive the brush 141 to scrape the end of the scraper head 132, thereby scraping the iron slag at the end of the scraper head 132 toward the discharge port 18, so that the iron slag loses the magnetic adsorption of the magnetic roller 12, and the iron slag falls out of the discharge port 18 through the scraper 131 and falls into the collection bin 181 for centralized treatment.

[0035] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
