Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing, and more specifically, to impurity removal equipment for iron concentrate processing. Background Art

[0002] Before iron ore concentrate is put into industrial use, it needs to go through a series of fine processing steps to ensure that its quality meets the requirements and improve its performance in practical applications. These processing steps mainly include crushing, fine grinding, magnetic separation and flotation, etc. Each step is crucial and together they determine the final quality of iron ore concentrate. In this series of steps, magnetic separation is a particularly critical link. Magnetic separation is the process of separating iron ore concentrate from other non-magnetic substances in iron ore by using magnetic differences. It requires that the input material flow is uniform and stable to ensure that the magnetic separation equipment can efficiently and accurately separate the iron ore concentrate. However, in the material feeding link before magnetic separation, the existing method usually relies on manual operation. Although this manual feeding method is simple and direct, it has obvious defects. Since manual feeding mainly relies on the operator's professional experience and feeling, it is difficult to accurately control the amount of feeding. This leads to fluctuations and gaps in the amount of feeding in actual operation. When different amounts of materials enter the magnetic separation equipment at the same time, it will cause uneven accumulation of the material flow, which will affect the effect of magnetic separation. Specifically, if the amount of material fed is too much, the magnetic separation equipment may not be able to handle it, resulting in incomplete separation of iron ore concentrate and non-magnetic materials, which reduces the purity of the iron ore concentrate; if the amount of material fed is too little, the processing capacity of the magnetic separation equipment may not be fully utilized, reducing production efficiency. In addition, uneven material flow accumulation may also affect the normal operation of the magnetic separation equipment and even damage the equipment. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model uses the power of motor 1 to rotate the slave gear meshing with the main gear. The rotation of the slave gear causes the inner shell to rotate inside the outer shell through the connecting shaft.

[0012] 2. The utility model uses a reinforcing rod to form a magnetic space for the circular magnet, which absorbs the iron impurities in the iron ore concentrate and causes them to fall from the holes on the surface of the mesh to the discharge port for discharge. At the same time, by starting motor 2 to rotate and change the position of the baffle, the reinforcing rod is closed to make the magnetic space disappear, and then the vibration device is started to make the workbench shake as a whole, so that the impurities on the surface of the mesh fall through the holes to the impurity removal port and are discharged. Compared with the traditional device, this device can directly capture the iron impurities, thereby efficiently removing the iron impurities in the iron concentrate, and at the same time, the mesh and the circular magnet are used in combination to ensure that the iron impurities are removed simultaneously during the screening process, thereby improving the screening efficiency. Moreover, the vibration effect of the vibration device can effectively prevent the accumulation and clogging of iron impurities on the mesh, thereby maintaining the screening efficiency and accuracy of the mesh.

[0021] When in use, the staff pours the iron ore fine powder from the top of the feed pipe 11 into the inner wall of the feed pipe 8 and drops into the inner shell 9 in sequence. Then the staff starts the motor 15. The power generated by the motor 15 makes the main gear 14 rotate. Since the main gear 14 is meshed with the slave gear 13, the main gear 14 drives the slave gear 13 to rotate synchronously while rotating. Then the inner shell 9 fixed at the bottom of the connecting shaft 12 also rotates while the slave gear 13 rotates. Through the rotation of the inner shell 9, the feed pipe 10 is connected with the feed pipe 7 after rotating one circle. At this time, the iron ore fine powder inside the inner shell 9 falls into the inside of the annular magnet 2 through the conveying pipe 5 for screening.

[0022] The power of motor 15 causes the slave gear 13 meshing with the main gear 14 to rotate. The rotation of the slave gear 13 causes the inner shell 9 to rotate inside the outer shell 6 through the connecting shaft 12. Then, the feed pipe 2 10 is connected to the feed pipe 7 after one circle of rotation. At this time, the iron ore concentrate inside the inner shell 9 falls from the inside of the conveying pipe 5 to the inside of the circular magnet 2 for screening. Compared with the traditional device, this device can effectively control the flow rate and speed of the material, so that the material is more evenly distributed during the screening process, thereby avoiding material accumulation or excessive impact on the screen, improving the screening efficiency, and at the same time, through indirect material discharge, it can reduce the direct impact of the material on the screening equipment, reduce the degree of equipment wear, extend the service life of the equipment, and reduce impurities and particles that do not meet the specifications in the iron ore concentrate, thereby improving the purity and quality of the product.

[0025] After the reinforcing rod 32 is used to form a magnetic space, the annular magnet 2 absorbs the iron impurities in the iron ore powder and then drops them from the holes on the surface of the mesh 16 to the discharge port 25 for discharge. At the same time, by starting the motor 24 to rotate and change the position of the baffle 23, the reinforcing rod 32 is closed to make the magnetic space disappear, and then the vibration device 27 is started to make the workbench 1 shake as a whole, so that the impurities on the surface of the mesh 16 drop through the holes to the impurity removal port 26 and are discharged. Compared with the traditional device, this device can directly capture iron impurities, thereby efficiently removing iron impurities in the iron ore powder, thereby efficiently removing iron impurities.

[0035] When in use, the staff pours the iron ore powder from the top of the feed pipe 11 and drops it into the inner shell 9 along the inner wall of the feed pipe 8 in sequence. Then the staff starts the motor 15. The power generated by the motor 15 causes the main gear 14 to rotate. Since the main gear 14 is meshed with the slave gear 13, the main gear 14 drives the slave gear 13 to rotate synchronously while rotating. The inner shell 9 fixed at the bottom of the connecting shaft 12 also rotates while the slave gear 13 rotates. Through the rotation of the inner shell 9, the feed pipe 10 is connected to the feed pipe 7 after rotating one circle. At this time, the iron ore powder inside the inner shell 9 falls into the inside of the circular magnet 2 through the conveying pipe 5 for screening.

[0036] Before the iron ore concentrate falls into the inside of the circular magnet 2, the staff starts the circular magnet 2 through the reinforcing rod 32, so that the circular magnet 2 forms a magnetic space, thereby adsorbing the iron impurities in the iron ore concentrate, and at the same time, the baffle 23 is rotated to the right fork of the human-shaped pipe 21 by the power of the motor 24, and the screened iron impurities fall through the holes on the surface of the mesh 16 to the left fork of the human-shaped pipe 21 and are discharged through the discharge port 25, and then the baffle 23 is rotated to the left fork of the human-shaped pipe 21 by the power of the motor 24 again. At this time, the magnetic space of the circular magnet 2 is closed by the reinforcing rod 32, and the iron impurities fall on the surface of the mesh 16, and then the vibration device 27 is started to shake the workbench 1 as a whole, so that the iron impurities on the surface of the mesh 16 fall from the holes and are discharged from the impurity removal port 26.
