For this reason, the applicant proposes an iron ore magnetic separation equipment for ore mining. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the process of iron ore mining, magnetic separation is required to separate the iron ore from the crushed stone. Therefore, an iron ore magnetic separation device for ore mining is needed. In the actual use of most traditional magnetic separation devices, there is a large amount of ore powder in the iron ore powder. After the ore powder comes into contact with the magnetic separation device of the device, it will block part of the iron ore powder, resulting in part of the iron ore powder not being well attracted by the magnetic separation device of the device, resulting in waste of resources and reducing the recovery rate of the iron ore powder. For this reason, the applicant proposes an iron ore magnetic separation device for ore mining.

[0024] like Figure 1-Figure 5As shown, the utility model provides a technical solution: an iron ore magnetic separation device for ore mining, comprising a plurality of iron ore magnetic separation stabilizing rods 1, a magnetic separation mechanism 2 is fixed on the top of the plurality of iron ore magnetic separation stabilizing rods 1, a crushing mechanism 3 is fixed on the feeding end of the magnetic separation mechanism 2, the magnetic separation mechanism 2 comprises a magnetic separation box 201, rotating rods 215 are rotatably connected to the inner wall of the magnetic separation box 201 on both sides, a flip plate 202 is rotatably connected to the middle of the outer wall of the rotating rod 215, a rubber strip 203 is fixed to the top of the inner wall of the magnetic separation box 201, and the two sides of the flip plate 202 are respectively in contact with one side of the rubber strip 203, arc-surface magnetic blocks 205 are rotatably connected to the inner wall of the magnetic separation box 201 on both sides, and soft pads 206 are respectively fixed on both sides of the arc-surface magnetic blocks 205, the flip plate 202 is located on one side of the arc-surface magnetic block 205, and torsion springs 204 are respectively fixed between the two ends of the flip plate 202 and the two ends of the rotating rod 215, and the inner wall of the magnetic separation box 201 is rotatably connected to the inner wall of the magnetic separation box 201. There is a scraper 207, and both sides of the scraper 207 are in contact with the two curved surfaces of the curved magnetic block 205 respectively. A first shell 208 is fixed to one side of the outer wall of the magnetic separation box 201, and three first motors 209 are fixed to one side of the inner wall of the first shell 208. After the output ends of the three first motors 209 pass through one side of the outer wall of the magnetic separation box 201, they are respectively fixed to the flip plate 202, the curved magnetic block 205 and one end of the scraper 207. An opening is provided on the bottom outer wall of the magnetic separation box 201, and a fixed frame 210 is fixed to the opening at the bottom of the magnetic separation box 201. A plurality of cylinders 211 are fixed to the top of the inner wall of the fixed frame 210, and a discharge plate 212 is fixed to the output ends of the plurality of cylinders 211. The top of the discharge plate 212 is in contact with the inner wall of the opening of the magnetic separation box 201 and both sides of the flip plate 202 respectively. A material accumulation box 213 is slidably connected to both sides of the outer wall of the fixed frame 210, and a material receiving box 214 is fixed to the discharge end of the magnetic separation box 201.

[0025] It should be noted that when the device is used, the iron ore is first placed in the crushing mechanism 3 for crushing, and the crushed ore powder enters the magnetic separation mechanism 2 through the pipeline. At this time, one of the first motors 209 will start, driving the rotating rod 215 to rotate, and the flip plate 202 will rotate along with the rotating rod 215 under the action of the two torsion springs 204. At this time, one side of the flip plate 202 will scrape up some of the ore powder in the magnetic separation box 201. When one side of the flip plate 202 contacts the rubber strip 203, the flip plate 202 will be blocked by the rubber strip 203. As the rotating rod 215 continues to rotate, the torsion spring 204 will apply pressure to the flip plate 202. When the pressure reaches a certain level, the flip plate 202 will separate from the rubber strip 203. The detached flip plate 202 will rotate rapidly and be limited according to the action of the torsion spring 204. At this time, one side of the flip plate 202 corresponds to the arc surface of one side of the arc magnetic block 205. The ore powder is quickly Under rotation, it separates from the flip plate 202. At this time, the ore powder will fall on the curved surface of one side of the curved magnetic block 205, and the ore powder will be screened according to the magnetic force of the curved magnetic block 205. When the iron ore powder on the curved surface of one side of the curved magnetic block 205 reaches a certain amount, the first motor 209 that controls the rotation of the rotating rod 215 will stop running. At this time, the second first motor 209 will drive the curved magnetic block 205 to rotate, and then stop. Then the third first motor 209 will drive the scraper 207 to rotate to collect the iron ore powder on the curved surface of the curved magnetic block 205. When the iron ore powder is scraped by the scraper 207 and contacts the soft pad 206, the iron ore powder will lose its magnetic force and fall into the collecting box 214 to be collected. When the ore powder in the magnetic separation box 201 is screened, the discharge plate 212 is lowered by controlling the cylinder 211. At this time, the crushed stone powder in the magnetic separation box 201 will be discharged and collected by the accumulation box 213.

[0027] It should be noted that when the device is in use, the iron ore is first placed in the feed box 301. At this time, a number of third motors 309 will drive a number of crushing rollers 302 to rotate to initially crush the iron ore. Subsequently, under the rotation of the second motor 304, the grinding column 305 will be driven to rotate, and the initially crushed iron ore powder will be ground by the grinding column 305 and the grinding tube 306. Subsequently, the ore powder will enter the inclined material tube 307 through the pipeline, and enter the magnetic separation mechanism 2 through the inclined material tube 307.
