Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of dry magnetic separator technology, and more specifically, to a dry magnetic separator for mining. Background Technology

[0002] Dry magnetic separators for mining play a crucial role in the mineral processing flow, specifically designed for separating minerals from dry materials. Their core operating mechanism is based on the differences in magnetic properties exhibited by different minerals. Inside the equipment, a strong magnetic field environment is created, typically generated by permanent magnets or electromagnets. When ore containing multiple minerals enters the magnetic field area created by the separator, magnetic minerals, such as magnetite, are attracted by the magnetic field; while minerals with weak or no magnetism, like common gangue, are largely unaffected and continue moving along their original trajectories. In this way, minerals with different magnetic properties are gradually separated under the influence of the magnetic field.

[0003] During the operation of a dry magnetic separator, when ores containing different minerals pass through the magnetic field area of ​​the separator, the magnetic minerals (such as magnetite) are attracted by the magnetic field, while the weakly magnetic or non-magnetic minerals (such as gangue) are unaffected by the magnetic field and continue to move along their original trajectories. Thus, minerals with different magnetic properties are separated under the action of the magnetic field.

[0004] However, when existing magnetic separators are in use, especially when iron-containing stone powder and iron-containing stone materials adsorbed on the outside of the outer roller fall off due to their own gravity after the magnetic attraction disappears, some residue will inevitably appear on the surface of the outer roller. If this residue is not cleaned in time as the magnetic separator runs for a long time, it will easily affect the magnetic separation effect of the magnetic roller. On the other hand, stopping the machine for cleaning will affect the working efficiency of the magnetic separator. Utility Model Content

[0026] The first toothed ring is fixedly mounted on the roller.

[0027] The second gear is rotatably disposed in the drive through groove, and the second gear meshes with the first gear ring and the first gear respectively.

[0031] The beneficial effects of the embodiments disclosed herein are as follows:

[0032] 1. In this disclosure, by setting up a magnetic system and a drum, during the feeding process into the housing through the feed inlet, the operation of the first motor can drive the drive disc to rotate, thereby using the magnetic force of the magnetic system to adhere the iron-containing stone and iron-containing stone powder to the drum. As the iron-containing stone powder and iron-containing stone move away from the magnetic system with the rotation of the drum, they can be separated from the surface of the drum under the action of gravity, thus facilitating the separation of the iron-containing stone from other ores and discharging them through the first discharge port and the second discharge port respectively.

[0033] 2. In this disclosure, by setting up a cleaning mechanism, after the mounting bracket is fixed in the mounting groove by bolts, the scraper can be pressed against the surface of the roller under the elastic force of the support spring, thereby facilitating the scraping of iron-containing stone powder adhering to the roller by the scraper.

[0034] 3. In this disclosure, through the setting of the drive mechanism and the cleaning roller, during the rotation of the roller, the meshing of the first gear ring and the second gear can drive the second gear to rotate, and at the same time, the meshing of the second gear and the first gear can drive the cleaning roller to rotate, so that the cleaning brush bristles on the cleaning roller can clean the iron-containing stone powder attached to the roller, thereby improving the cleaning effect.

[0035] 4. In this disclosure, the arrangement of the drum, magnetic system, drive disc, first motor and cleaning mechanism facilitates the cleaning of iron-containing stone powder adhering to the drum by rotating the cleaning roller in conjunction with the scraping plate, thereby solving the technical problem in the prior art that iron-containing magnetic powder easily adheres to the drum surface and affects the magnetic separation effect.

[0045] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0046] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0047] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0048] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0050] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] like Figures 1-7 The diagram illustrates a dry magnetic separator for mining according to an embodiment of this disclosure. It includes a housing 1, with a feed inlet 2 on the inner top wall and a first discharge outlet 3 and a second discharge outlet 4 on opposite sides of the inner bottom wall. The separator also includes a drum 5, a magnetic system 6, a drive disc 7, a first motor 8, and a cleaning mechanism. Limiting grooves are formed on two opposite side walls of the housing 1, with the drum 5 rotatably positioned between the bottoms of the two limiting grooves. The magnetic system 6 is fixedly disposed at the bottom of one of the limiting grooves, and is arc-shaped, contacting the inner wall of the drum 5. The drive disc 7 is fixedly disposed at one end of the drum 5. The first motor 8 is mounted on the side wall of the housing 1, and its output end is fixedly connected to the drum 5. The cleaning mechanism is disposed on the housing 1 and is used to clean iron-containing particles adhering to the surface of the drum 5. Stone powder is cleaned. The inner top and bottom walls of the shell 1 are fixedly equipped with partition plates 9. The side walls of the shell 1 are fixedly equipped with support blocks 10. The top side walls of the support blocks 10 are inclined towards the drum 5. Multiple support legs 23 are fixedly equipped on the shell 1. Specifically, during the feeding process into the shell 1 through the feed port 2, the operation of the first motor 8 can drive the drive disk 7 to rotate. Thus, the iron-containing stone and iron-containing stone powder can be attached to the drum 5 by the magnetic force of the magnetic system 6. When the iron-containing stone powder and iron-containing stone move away from the magnetic system 6 as the drum 5 rotates, the iron-containing stone powder and iron-containing stone can be separated from the surface of the drum 5 under the action of gravity. This facilitates the separation of the iron-containing stone from other ores and discharges them through the first discharge port 3 and the second discharge port 4 respectively.

[0052] Reference Figures 1-7The cleaning mechanism includes a mounting groove 11, a mounting frame 12, a scraping mechanism, a sweeping mechanism, and a fixing mechanism. The mounting groove 11 is formed on the side wall of the housing 1 and communicates with a limiting groove. The mounting frame 12 is slidably disposed within the mounting groove 11. The scraping mechanism is disposed on the mounting frame 12 and is used to scrape off iron-containing stone powder adhering to the roller 5. The sweeping mechanism is disposed on the mounting frame 12 and is used to sweep away iron-containing stone powder adhering to the roller 5. The fixing mechanism is disposed between the mounting frame 12 and the housing 1 and is used to install and fix the mounting frame 12 to the housing 1. The fixing mechanism includes a fixing plate 13 and bolts 14. The fixing plate 13 is fixedly disposed within the housing 1. On the mounting bracket 12, bolts 14 are threaded through and installed between the fixing plate 13 and the housing 1. The scraping mechanism includes a support cover 15 and a support spring 17. The support cover 15 is fixedly installed on the mounting bracket 12. A scraping plate 16 is slidably installed inside the support cover 15. The scraping plate 16 contacts the roller 5. The support spring 17 is fixedly installed between the bottom of the support cover 15 and the scraping plate 16. Specifically, after the mounting bracket 12 is fixed in the mounting groove 11 by bolts 14, the scraping plate 16 can be pressed against the surface of the roller 5 under the elastic force of the support spring 17, thereby facilitating the scraping of iron-containing stone powder attached to the roller 5 by the scraping plate 16.

[0053] Reference Figures 3-7 The cleaning mechanism includes a cleaning roller 18, a drive channel 19, and a drive mechanism. The cleaning roller 18 is rotatably mounted in the mounting frame 12. Cleaning bristles are evenly distributed on the sidewalls of the cleaning roller 18 and contact the roller 5. The drive channel 19 is opened on the mounting frame 12, and a first gear 20 is rotatably mounted at the bottom of the drive channel 19. A connecting rod is fixedly installed between the first gear 20 and the cleaning roller 18. The drive mechanism is mounted on the mounting frame 12 and is used to drive the cleaning roller 18 to rotate. The drive mechanism includes an annular groove, a first toothed ring 21, and a second gear 22. The annular groove is opened at a limiting position. On the side wall of the groove, the first toothed ring 21 is fixedly mounted on the roller 5, and the second gear 22 is rotatably mounted in the drive through groove 19. The second gear 22 meshes with the first toothed ring 21 and the first gear 20 respectively. Specifically, during the rotation of the roller 5, the meshing of the first toothed ring 21 and the second gear 22 can drive the second gear 22 to rotate. At the same time, the meshing of the second gear 22 and the first gear 20 can drive the cleaning roller 18 to rotate. Thus, the cleaning brush bristles on the cleaning roller 18 can clean the iron-containing stone powder attached to the roller 5, thereby improving the cleaning effect.

[0054] Reference Figure 3A sealing ring is fixedly installed on the inner wall of the limiting groove. The sealing ring is in contact with the roller 5. The mounting frame 12 is in contact with the roller 5. A sealing gasket is fixedly installed at one end of the mounting frame 12 and the roller 5. This can seal the first gear ring 21, the first gear 20 and the second gear 22, thereby preventing the iron-containing stone powder from affecting the conduction of the first gear 20, the second gear 22 and the first gear ring 21.

[0055] In this embodiment, during use, after the operator fixes the mounting bracket 12 into the mounting groove 11 using bolts 14, the scraper 16 is pressed against the surface of the roller 5 under the elastic force of the support spring 17. Then, during the process of feeding material into the housing 1 through the feed inlet 2, the operation of the first motor 8 drives the drive disc 7 to rotate. This allows the iron-containing stone and iron-containing stone powder to adhere to the roller 5 through the magnetic force of the magnetic system 6. As the iron-containing stone and iron-containing stone move away from the magnetic system 6 with the rotation of the roller 5, they are forced to move away from the magnetic system 6 under the influence of gravity. The surface of the roller 5 is detached, which facilitates the separation of iron-containing stone from other ores and their discharge through the first discharge port 3 and the second discharge port 4 respectively. At this time, during the rotation of the roller 5, the meshing of the first gear ring 21 and the second gear 22 drives the second gear 22 to rotate. At the same time, the meshing of the second gear 22 and the first gear 20 drives the cleaning roller 18 to rotate. Thus, the cleaning brush bristles on the cleaning roller 18 can clean the iron-containing stone powder attached to the roller 5, thereby improving the cleaning effect. At the same time, the scraper plate 16 can further clean the roller 5.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
