Description

Technical Field

[0001] This utility model relates to the field of iron ore magnetic separation technology, and in particular to a magnetic separator for iron ore crushing. Background Technology

[0002] In the mining and processing industry, iron ore is an important metal resource, and its post-mining processing is crucial. Magnetic separation is a commonly used separation method in iron ore processing. However, existing magnetic separators do not thoroughly clean the residual material on the roller surface after the magnetic roller has adsorbed the magnetic material. The residual magnetic material will affect the subsequent magnetic separation accuracy and efficiency, leading to resource waste. Furthermore, the rotation of the magnetic roller is driven by the transmission system, but the transmission structure of some equipment is not reasonably designed, which can easily lead to unstable rotation during operation, affecting the magnetic separation effect and increasing the risk of equipment failure. Therefore, we have introduced a magnetic separator for iron ore crushing. Utility Model Content

[0003] The main purpose of this invention is to provide a magnetic separator for iron ore crushing, which can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A magnetic separator for iron ore crushing includes a base plate, with support plates fixedly connected to the upper left and upper right sides of the base plate, and an upper plate fixedly connected to the upper middle of the two support plates. A cleaning device is fixedly connected to the upper middle of the upper plate, and a sliding groove is opened on the upper part of the inner wall of the two support plates.

[0006] The cleaning device includes an electric push rod. The output end of the electric push rod passes through the upper plate and is fixedly connected to a cleaning long plate. Slider blocks are fixedly connected to the upper left and upper right ends of the cleaning long plate. Two connecting blocks are fixedly connected to the upper front and upper rear ends of the cleaning long plate, and the connecting blocks are symmetrically distributed in pairs. A short shaft is movably connected between the left and right ends of the two connecting blocks. A tension spring base is sleeved on the middle of the outer surface of the short shaft. A tension spring body is fixedly connected between the tension spring bases. A fixing rod is inserted between the two tension spring bases on the upper front side and between the two tension spring bases on the upper rear side. The electric push rod is fixedly installed in the middle of the upper part of the cleaning device.

[0007] Preferably, the two ends of the front fixing rod and the rear fixing rod are fixedly connected to the right end of the left support plate and the left end of the right support plate, respectively. The two sliders are located in the slide grooves, and the four tension spring bodies are inclined at a 30-degree angle.

[0008] Preferably, a guide plate is fixedly connected between the left and right walls of the two support plates, and the two guide plates are distributed in a mirror image on the front and rear sides of the upper plate. A side plate is fixedly connected to the middle of the right end of the support plate on the right side, and a magnetic suction device is fixedly connected to the right end of the side plate. A collection box is placed at the front and rear of the upper end of the bottom plate.

[0009] Preferably, the magnetic attraction device includes a drive motor, the output end of which passes through the side plate and is fixedly connected to a main gear. A secondary gear is meshed with the front of the outer surface of the main gear. A movable shaft is fixedly connected to the middle of the right end of the secondary gear. A rotating rod is fixedly connected to the middle of the left end of the secondary gear. A magnetic attraction roller is fixedly connected to the outer surface of the rotating rod. Limiting plates are fixedly connected to the left and right sides of the outer surface of the magnetic attraction roller. A front scraper is provided on the lower front side of the two limiting plates. Two notches are opened on the left and right front ends of the front scraper. The drive motor is fixedly connected to the right end of the side plate.

[0010] Preferably, the right end of the movable shaft is movably connected to the right wall of the side plate via a bearing, the left end of the rotating rod is movably connected to the right end of the left support plate via a bearing, and the diameter of the main gear is larger than the diameter of the secondary gear.

[0011] The above solution involves a main gear with a larger diameter than the secondary gear, which can stably transmit power, increase the rotation speed, and ensure smooth rotation of the magnetic roller, thus guaranteeing the magnetic separation effect.

[0012] Preferably, the front scraper is inclined at a 30-degree angle and is located directly above the collection box, with the rear side of the front scraper located in front of the magnetic roller.

[0013] The above solution involves a 30-degree tilt design for the front scraper, which utilizes gravity to easily scrape the magnetic material adsorbed on the magnetic roller into the collection box directly above.

[0014] Preferably, the cleaning plate is located directly above the magnetic roller, and the length of the cleaning plate is the same as the length of the magnetic roller.

[0015] The above solution involves a cleaning plate positioned directly above the magnetic roller and of equal length, which completely covers the surface of the magnetic roller. This ensures that all residual magnetic material on the surface of the magnetic roller is cleaned during cleaning operations, avoiding blind spots, improving cleaning efficiency, and ensuring the cleanliness of the magnetic separator.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In this utility model, through the cooperation of electric push rod, slider and slide groove, and elastic structure design such as tension spring body, the cleaning device can move down smoothly and adaptively adjust the pressure. The cleaning plate is the same length as the magnetic roller and fully covers it, thoroughly cleaning the residual magnetic material on the surface of the magnetic roller, avoiding the residual material from affecting the subsequent magnetic separation, and significantly improving the magnetic separation accuracy and resource utilization.

[0018] 2. In this utility model, the diameter difference design between the main gear and the secondary gear in the magnetic attraction device ensures stable power transmission, drives the magnetic attraction roller to rotate smoothly, and prevents material from slipping with the limit plate. The front scraper is installed on the front side of the magnetic attraction roller to accurately scrape off magnetic materials, effectively avoiding the problem of poor magnetic separation effect caused by unstable transmission, reducing the risk of equipment failure, and ensuring stable and efficient magnetic separation operation.

[0027] Please see Figure 1-4 This utility model provides a technical solution:

[0028] A magnetic separator for iron ore crushing includes a base plate 1. Support plates 2 are fixedly connected to the upper left and upper right parts of the base plate 1. An upper plate 5 is fixedly connected to the upper middle part of the two support plates 2. A cleaning device 6 is fixedly connected to the upper middle part of the upper plate 5. A sliding groove 9 is opened on the upper part of the inner wall of the two support plates 2.

[0029] A guide plate 7 is fixedly connected between the left and right walls of the two support plates 2, and the two guide plates 7 are distributed in a mirror image on the front and rear sides of the upper plate 5. A side plate 3 is fixedly connected to the middle of the right end of the support plate 2 on the right side, and a magnetic suction device 4 is fixedly connected to the right end of the side plate 3. A collection box 8 is placed at the front and rear of the upper end of the bottom plate 1.

[0030] In this embodiment, the cleaning device 6 includes an electric push rod 61. The output end of the electric push rod 61 passes through the upper plate 5 and is fixedly connected to a cleaning long plate 62. Slider 63s are fixedly connected to the upper left and upper right ends of the cleaning long plate 62. Two connecting blocks 64 are fixedly connected to the upper front and upper rear ends of the cleaning long plate 62, and the connecting blocks 64 are symmetrically distributed in pairs. A short shaft 68 is movably connected between the left and right ends of the two connecting blocks 64. A tension spring base 66 is sleeved on the middle of the outer surface of the short shaft 68. A tension spring body 67 is fixedly connected between the tension spring bases 66. A fixing rod 65 is interwoven between the two tension spring bases 66 on the upper rear side. An electric push rod 61 is fixedly installed in the middle of the upper end of the cleaning device 6. The two ends of the fixing rod 65 on the front side and the fixing rod 65 on the rear side are fixedly connected to the right end of the left support plate 2 and the left end of the right support plate 2, respectively. Two sliders 63 are located in the slide groove 9. The four tension spring bodies 67 are tilted at a 30-degree angle. The cleaning long plate 62 is located directly above the magnetic suction roller 46. The length of the cleaning long plate 62 is the same as the length of the magnetic suction roller 46.

[0031] Through the above scheme: when the cleaning device 6 is working, the electric push rod 61 is activated, and its output end passes through the upper plate 5 to push the cleaning plate 62 downward. The sliders 63 at both ends of the cleaning plate 62 slide along the slide grooves 9 of the support plate 2 to ensure smooth movement. When the cleaning plate 62 contacts the magnetic roller 46, the elastic structure composed of the connecting block 64, the short shaft 68, the tension spring base 66 and the tension spring body 67 inclined at 30 degrees plays a role. It can adaptively adjust the pressure according to the surface condition of the magnetic roller 46 to avoid rigid contact damage to the equipment. Since the cleaning plate 62 is the same length as the magnetic roller 46 and is located directly above it, it can fully cover the surface of the magnetic roller 46. Under the drive of the electric push rod 61, the residual magnetic material on the surface of the magnetic roller 46 is swept to the front collection box 8.

[0032] In this embodiment, the magnetic attraction device 4 includes a drive motor 41. The output end of the drive motor 41 passes through the side plate 3 and is fixedly connected to a main gear 42. A secondary gear 43 is meshed with the front of the outer surface of the main gear 42. A movable shaft 44 is fixedly connected to the middle of the right end of the secondary gear 43. A rotating rod 47 is fixedly connected to the middle of the left end of the secondary gear 43. A magnetic attraction roller 46 is fixedly connected to the outer surface of the rotating rod 47. Limiting plates 410 are fixedly connected to the left and right sides of the outer surface of the magnetic attraction roller 46. The front side of the two limiting plates 410 is lower... The unit is equipped with a front scraper 48, with two notches 49 on the left and right sides of the front end of the front scraper 48. The drive motor 41 is fixedly connected to the right end of the side plate 3. The right end of the movable shaft 44 is movably connected to the right wall of the side plate 3 through a bearing. The left end of the rotating rod 47 is movably connected to the right end of the support plate 2 on the left side through a bearing. The diameter of the main gear 42 is larger than the diameter of the secondary gear 43. The front scraper 48 is tilted at a 30-degree angle and is located directly above the collection box 8. The rear side of the front scraper 48 is located in front of the magnetic suction roller 46.

[0033] Through the above scheme: When the magnetic suction device 4 is working, the drive motor 41 is fixed to the right end of the side plate 3. After starting, its output end drives the main gear 42 to rotate. The main gear 42 drives the secondary gear 43 through meshing. Since the diameter of the main gear 42 is larger than that of the secondary gear 43, it can stably transmit power. The secondary gear 43 drives the movable shaft 44, the rotating rod 47 and the magnetic suction roller 46 to rotate. The magnetic suction roller 46 relies on magnetic adsorption to adsorb magnetic substances in the crushed iron ore material. The limiting plate 410 can prevent the material from slipping left and right on the roller surface. When the magnetic suction roller 46 rotates the adsorbed magnetic material to the front scraper 48, the front scraper 48 is tilted at 30 degrees and located directly above the collection box 8. The rear side is close to the front side of the magnetic suction roller 46, which can scrape the magnetic material into the collection box 8. The notch 49 at the front end of the front scraper 48 can reduce the contact friction with the magnetic suction roller 46.

[0034] It should be noted that this utility model is a magnetic separator for iron ore crushing. Before screening the iron ore crushed material, the front scraper 48 is not engaged and installed on the front side of the magnetic roller 46. The iron ore to be processed is placed on the device, and the drive motor 41 is started. The output end of the drive motor 41 drives the main gear 42 to rotate. The main gear 42 meshes with the secondary gear 43, thereby driving the secondary gear 43 to rotate. The secondary gear 43 drives the rotating rod 47 and the magnetic roller 46 to rotate. During the rotation, the magnetic roller 46 uses its own magnetism to attract the magnetic materials in the iron ore crushed material. The material is adsorbed onto its surface. Because the diameter of the main gear 42 is larger than that of the secondary gear 43, the magnetic roller 46 can rotate stably under the drive of the main gear 42. The material not adsorbed by the magnetic roller 46 falls into the collection box 8 placed on the upper end of the base plate 1 under the action of gravity. The collection box 8 can then be removed to complete the collection of non-magnetic materials. After the magnetic roller 46 has completed the adsorption of magnetic materials, the front scraper 48 is snapped and installed on the front side of the magnetic roller 46. The front scraper 48 is tilted at a 30-degree angle and is located directly above the collection box 8, with its rear side located at... On the front side of the magnetic roller 46, as the magnetic roller 46 continues to rotate, the magnetic material adsorbed on its surface is carried to the front scraper 48, where it is scraped off and falls into the collection box 8 at the rear of the upper end of the base plate 1. Subsequently, the cleaning device 6 is activated, and the electric push rod 61 is started. Its output end pushes the cleaning plate 62 downward. The slider 63 on the cleaning plate 62 slides in the groove 9 of the support plate 2, ensuring that the cleaning plate 62 moves downward smoothly. The length of the cleaning plate 62 is the same as the length of the magnetic roller 46, which can achieve full coverage. When the cleaning plate 62 contacts... After reaching the surface of the magnetic roller 46, the residual magnetic material on the surface of the magnetic roller 46 is swept off by the electric push rod 61. This residual magnetic material is guided to the front by the guide plate 7 and falls into the collection box 8 on the front. The tension spring body 67 connected to the cleaning plate 62 is fixed by the tension spring base 66, the short shaft 68 and the fixing rod 65. The four tension spring bodies 67, which are inclined at a 30-degree angle, play a role in buffering and self-adjustment during the cleaning process, ensuring good contact between the cleaning plate 62 and the surface of the magnetic roller 46 and improving the cleaning effect.
