Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and more specifically, to a magnetic separator for screening iron ore. Background Technology

[0002] A magnetic separator is a device that uses magnetic force to separate minerals. It plays an important role in the screening of iron ore. Magnetic separators separate minerals based on their differences in magnetic properties. According to the strength of the magnetic properties of different minerals, magnetic separators can separate iron-bearing ores, such as iron ore and magnetite, from gangue minerals, such as quartz and feldspar. During operation, the ore is first fed into the magnetic separator through a feeding device. Under the action of a strong magnetic field, magnetic mineral particles are adsorbed onto the magnetic drum, while non-magnetic minerals are discharged, thus achieving separation. Since the flow rate of iron ore material during the magnetic separation process affects the magnetic separation effect, it is necessary to perform magnetic separation material control operation on iron ore.

[0003] In related technologies, during the use of magnetic separators, iron ore materials are generally transported by external conveying equipment, and the iron ore materials are controlled during the conveying process for use.

[0004] However, in the current use of magnetic separators, the conveying equipment can only control the conveying speed of iron ore materials, while the contact thickness between the material and the magnetic separator drum during magnetic separation is difficult to control. This makes it difficult for the magnetic separator drum to perform sufficient magnetic separation on the outside of the iron ore material, affecting the convenience of material control and the magnetic separation effect of the magnetic separator.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a technical solution: a magnetic separator for iron ore screening, including a magnetic separator body 1 and a screening and material control structure. A magnetic separator cylinder 2 is installed at the top inside the magnetic separator body 1, and a material plate 3 is installed at the bottom inside the magnetic separator body 1. This provides a medium for users to control the thickness of iron ore materials, so that users can control the magnetic separation thickness of iron ore materials when the magnetic separator cylinder 2 is working. This avoids the situation where it is difficult to control the thickness of iron ore materials when using the magnetic separator cylinder 2, resulting in insufficient magnetic separation of iron ore. Therefore, it improves the convenience of magnetic separation material control and the magnetic separation effect of the magnetic separator cylinder 2.

[0031] Reference Figures 1-4 In a preferred embodiment, the screening and material control structure includes a material control hopper 4, which is movably connected to the right side of the front of the magnetic separator 2. A movable hopper 5 is movably connected to the left side of the material control hopper 4. A material control trough 6 is opened on the left side of the material control hopper 4. A material control frame 7 is movably connected inside the material control trough 6. The left side of the material control frame 7 is fixedly connected to the right side of the movable hopper 5. A material control support mechanism is movably connected to the bottom of the material control hopper 4 and the movable hopper 5. The material control hopper 4 and the movable hopper 5 are moved to the front of the magnetic separator 2 by hand, and the material control hopper 4 and the movable hopper 5 are moved to both sides according to the size of the magnetic separator 2. At this time, the material control frame 7 moves inside the material control trough 6, performing a moving and expanding operation between the material control hopper 4 and the movable hopper 5. Then, according to the magnetic field strength of the magnetic separator 2 on the external iron ore material... To meet the control requirements, the movable hopper 5 and the control hopper 4 are moved to adjust the gap between the control hopper 4, the movable hopper 5 and the magnetic separator 2, satisfying the thickness control requirements of the iron ore. The magnetic separator 2 is used to magnetically attract and control the thickness of the material. The material control support mechanism includes a support frame 8, a support groove 9 and a support rod 10. The support frame 8 is movably connected to the bottom of the control hopper 4 and the movable hopper 5. The support groove 9 is opened at the top of the support frame 8. The support rod 10 is movably connected inside the support groove 9. This provides stable support for the control hopper 4 and the movable hopper 5, ensuring stability during operation and preventing instability. Therefore, it improves the stability and convenience of supporting the control hopper 4 and the movable hopper 5.

[0032] Reference Figures 2-3In a preferred embodiment, a connecting groove 11 is provided at the top of the support rod 10. A connecting seat 12 is movably connected to the inside of the connecting groove 11 via a shaft pin. The top of the connecting seat 12 is fixedly connected to the bottom of the control hopper 4 and the movable hopper 5, respectively. This can prevent the control hopper 4 and the movable hopper 5 from separating from the support rod 10 during use, thus improving the connection effect between the support rod 10 and the control hopper 4 and the movable hopper 5. A positioning seat 13 is movably connected to the top of the outer side of the support frame 8. A positioning column 14 is fixedly connected to the top of the inner side of the positioning seat 13. The movable hopper 5, the control hopper 4, and the support rod 10 can be positioned by the connecting seat 12, avoiding the difficulty in positioning the connecting seat 12 during use, thus improving the positioning convenience of the connecting seat 12.

[0033] Reference Figures 2-4 In a preferred embodiment, a positioning plate 15 is fixedly connected to the outside of the connecting seat 12. A positioning groove 16 is provided on the outside of the positioning plate 15. The inside of the positioning post 14 is located inside the positioning groove 16. This provides the positioning post 14 with multiple mediums and spaces for positioning the connecting seat 12, avoiding the situation where the positioning post 14 cannot meet the positioning requirements of the connecting seat 12. Therefore, the positioning flexibility of the positioning post 14 is improved. A slide 17 located at the bottom of the positioning seat 13 is fixedly connected to the outside of the support rod 10. A slide 18 is magnetically connected inside the slide 17. The top of the slide 18 is fixedly connected to the bottom of the positioning seat 13. This allows for a sliding connection between the positioning seat 13 and the support frame 8 to prevent separation, thus improving the stability of the positioning seat 13 in use.

[0034] Reference Figures 2-4 In a preferred embodiment, a magnetic plate 19 is embedded and connected to the front side of the inner wall of the support groove 9, and a magnetic suction plate 20, which is magnetically connected to the magnetic plate 19, is embedded and connected to the front side of the support rod 10. This allows for magnetic pre-positioning between the support rod 10 and the support groove 9, preventing difficulties in pre-positioning the support rod 10 during use and avoiding inconvenience in subsequent operations. Therefore, the positioning operation of the support rod 10 is made more convenient. A screw cylinder 21 is fixedly connected to the top of the outer side of the support frame 8. The screw cylinder 21 has a threaded connection to a stud 22 that penetrates into the support groove 9. This provides a medium for the user to perform magnetic positioning between the support rod 10 and the support frame 8, preventing difficulties in stabilizing the support rod 10 with the support frame 8 during use. This also improves the positioning convenience of the support rod 10.

[0035] Specifically, the working process or working principle of this magnetic separator for iron ore screening is as follows: During use, according to the height, size, and thickness control requirements of the magnetic separator drum 2, the support rod 10 is held to move the control hopper 4 and the movable hopper 5 up and down, adjusting their height. At this time, the magnetic suction plate 20 moves with the support rod 10, cooperating with the magnetic plate 19 to perform magnetic positioning between the support rod 10 and the support groove 9. The stud 22 is then held and rotated to cooperate with the screw sleeve, applying a clamping force to the support rod 10, thus securing the support rod 10 against the support frame 8. After initial positioning, manually move the movable hopper 5 and control hopper 4 to both sides to adjust their control range. Simultaneously, the control frame 7 moves with the movable hopper 5 inside the control trough 6, extending the distance between the control hopper 4 and the movable hopper 5. Holding the control hopper 4, the control frame 7 moves the movable hopper 5, adjusting their angle to meet the subsequent iron ore material thickness control requirements of the magnetic separator 2. At this point, the connecting seat 12 follows the movable hopper 5 and control hopper 4 in the connection... The internal movement of the groove 11 enables a rotational connection between the control hopper 4, the movable hopper 5, and the support rod 10. Simultaneously, the positioning plate 15 drives the positioning groove 16 to move along with the connecting seat 12. Then, the handheld positioning seat 13 moves the positioning column 14 inward into the positioning groove 16, allowing the positioning column 14 to perform angular positioning of the control hopper 4 and the movable hopper 5 through the positioning plate 15 and the connecting seat 12. At this time, the slide 18 moves along with the positioning seat 13 within the slide frame 17, enabling a sliding connection and magnetic positioning between the positioning seat 13 and the support frame 8. Subsequently, the handheld support... The support frame 8, together with the support rod 10, drives the control hopper 4 and the movable hopper 5 to move towards the magnetic separator 2, so that the gap between the control hopper 4, the movable hopper 5 and the magnetic separator 2 meets the thickness control requirements of the external iron ore material. When the external iron ore material comes into contact with the magnetic separator 2 and the magnetic separation thickness is too large, the control hopper 4, together with the control frame 7 and the movable hopper 5, receives the iron ore material that exceeds the thickness range and guides the received ore material so that the received iron ore is discharged and continues to be magnetically separated, so that the user can control the magnetic separation thickness of the external iron ore.

[0036] It should be noted that the magnetic separator body 1, magnetic separator cylinder 2 and material plate 3 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
