Technical Field
[0001] This utility model relates to the technical field of fine magnetic separation equipment for low-grade iron ore, specifically a fine magnetic separation equipment for low-grade iron ore that can reduce dust generation. Background Technology
[0002] The demand for iron ore is increasing, but rich or relatively rich iron ore cannot meet the market demand. The development and utilization of poor and ultra-poor magnetite ore is receiving more and more attention. Low-grade iron ore fine particles need to be removed by magnetic separation equipment to remove impurities.
[0003] However, a utility model patent with authorization announcement number CN109351468B discloses a magnetic separation device, particularly a rare earth iron ore magnetic separation device. Technical problem: To provide a swing-type magnetic separation device for iron ore, a small-batch magnetic separation device for iron ore, and a rare earth iron ore magnetic separation device with high magnetic separation efficiency. Technical solution: A rare earth iron ore magnetic separation device includes a small rack, a first rotating shaft, a motor, a rotating wheel, saw teeth, a moving frame, a first pull rope, a fixed pulley, a second pull rope, a first spring, etc.; through holes are provided on the lower left and right walls of the housing; moving rails are symmetrically arranged on the left and right sides of the bottom of the housing; collection troughs are symmetrically arranged on the left and right sides of the bottom of the housing, and the collection troughs are located above the moving rails. This invention achieves the effects of swing-type magnetic separation of iron ore, small-batch magnetic separation of iron ore, and high magnetic separation efficiency. This equipment uses a lower funnel to release rare earth elements in small batches. The rare earth elements swing and disperse on the slide plate, and the iron ore is adsorbed on the slide plate and the baffle. In addition, during this process, the striking device works to strike the baffle, so that the iron ore is quickly collected, resulting in high magnetic separation efficiency.
[0004] The existing technical solutions mentioned above have the following drawbacks: fine particles are fed into the guide rail through a hopper, but the fine particles tend to accumulate, reducing the magnetic separation effect. Furthermore, the guide rail is struck by components such as striking blocks and swing rods to feed the particles, but the structure is relatively complex. In addition, the hopper is open, and dust easily floats to the outside during magnetic separation, causing dust pollution. Therefore, we propose a low-grade iron ore fine particle magnetic separation device that can reduce dust pollution in order to solve the problems mentioned above. Utility Model Content

[0032] 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.
[0033] Please see Figure 1-6 This utility model provides a technical solution: a low-grade iron ore fine-particle magnetic separation device that can reduce dust, including a storage tank 1, a support frame 2, a first connecting shaft 3, a first motor 4, a first stirring rod 5, a second stirring rod 6, a discharge port 7, a guide channel 8, an electromagnet plate 9, a box 10, a storage frame 11, a mounting plate 12, a second connecting shaft 13, a second motor 14, a connector 15, a connecting plate 16, an adjusting rod 17, a connecting block 18, a vibrating plate 19, a protective plate 20, a mounting block 21, a third connecting shaft 22, and a third motor 23.
[0034] Example 1: Existing hoppers are open, and dust easily floats to the outside when magnetically charged, causing dust pollution. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 and Figure 5Since the third connecting shaft 22 is rotatably connected to the upper left end of the storage barrel 1, and the storage frame 11 is nested inside the box 10, the storage barrel 1 is connected to the storage frame 11 through the discharge port 7 and the guide channel 8. The protective plate 20 is in a rotating structure on the upper side of the storage barrel 1 through the mounting block 21 and the third connecting shaft 22. Therefore, the low-grade iron ore fine particles to be magnetically separated are poured into the inside of the storage barrel 1. When the third motor 23 works, it drives the third connecting shaft 22 to rotate at the upper left end of the storage barrel 1. When the third connecting shaft 22 rotates, it drives the protective plate 20 to rotate through the mounting block 21, so that the third connecting shaft 22 rotates to the top of the storage barrel 1 and covers the top of the storage barrel 1, so that the dust will not float out through the top of the storage barrel 1. The dust after magnetic separation enters the inside of the storage frame 11 through the guide channel 8. The storage frame 11 is placed inside the box 10, so that the dust in the storage frame 11 will not float in the air, thus easily reducing dust.
[0035] Example 2: Existing methods use a hopper to allow fine particles to fall into the guide rail, but the fine particles tend to accumulate, reducing the effectiveness of magnetic separation. Therefore, this example uses the following technical solution: Figure 1 , Figure 3 and Figure 4 The stirring structure includes a first connecting shaft 3, a first motor 4, a first stirring rod 5, a second stirring rod 6, and a discharge port 7. The first stirring rod 5 is fixedly connected to the outer surface of the first connecting shaft 3 at equal angles. The second stirring rod 6 is embedded and connected to the inner wall of the first stirring rod 5 at equal intervals. Both the first stirring rod 5 and the second stirring rod 6 rotate inside the storage tank 1 via the first connecting shaft 3. The discharge port 7 is opened at equal intervals at the lower right end of the storage tank 1. Therefore, when the first motor 4 is working, it drives the first connecting shaft 3 to rotate inside the storage tank 1. When the connecting shaft 3 rotates, it drives the first stirring rod 5, which is set at equal angles, and the second stirring rod 6, which is set at equal intervals, to rotate. This causes the first stirring rod 5 and the second stirring rod 6, which are set at equal angles, to stir the fine particles inside the storage tank 1. The fine particles are then evenly dispersed inside the guide channel 8 through the feed inlet 7, which is set at equal intervals. When the electromagnet plate 9 is energized, the iron is attracted to the bottom of the guide channel 8, while the impurities slide into the collection frame 11 for collection. This makes it easier for the low-grade iron ore fine particles to be evenly dispersed on the guide channel 8.
[0036] Example 3: Existing methods use striking blocks, rocker arms, and other components to punch and cut the guide rail, but these methods are relatively complex. Therefore, this example uses the following technical solution: Figure 1 , Figure 2 and Figure 6The vibration structure includes a mounting plate 12, a second connecting shaft 13, a second motor 14, a connector 15, a connecting plate 16, an adjusting rod 17, a connecting block 18, and a vibration plate 19. The material guide channel 8 is inclined, and the right end of the material guide channel 8 is engaged with the inside of the left end of the housing 10. A storage frame 11 is nested inside the housing 10. A connecting block 18 with a "convex" shaped longitudinal section is embedded in the upper middle end of the adjusting rod 17. A connector 15 with an "S" shaped longitudinal section is fixedly connected to the front end of the second connecting shaft 13. The vibration plate 19 has a lifting structure above the material guide channel 8 through the connector 15 and the connecting block 18. Therefore, after the impurities are collected, a new storage frame 11 is nested inside. Inside the housing 10, the electromagnet plate 9 is de-energized. When the second motor 14 is working, it drives the second connecting shaft 13 to rotate on the mounting plate 12. When the second connecting shaft 13 rotates, it drives the connector 15 to rotate. The "S"-shaped connector 15 and the connecting block 18 cooperate to allow the adjusting rod 17 to rise and fall inside the upper and lower sets of connecting plates 16. The adjusting rod 17 drives the vibrating plate 19 to rise and fall. When the vibrating plate 19 rises and falls, its lower end collides with the upper end of the guide channel 8, causing the guide channel 8 to vibrate. This allows the fine particles inside the guide channel 8 to slide into the storage frame 11 through the inclined direction of the guide channel 8, thus facilitating the rapid collection of low-grade iron ore fine particles. All the electrical components mentioned above are existing technologies and will not be described in detail here.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
