Description
Technical Field
[0001] The utility model relates to the technical field of magnetic separators, in particular to a sealing device for a magnetic separator. Background Art
[0002] Belt magnetic separators are devices widely used in industrial production, mainly used for automatically removing ferromagnetic impurities from materials. These devices play a crucial role in industries such as coal, metallurgy, ore, and building materials. The main function of belt magnetic separators lies in their high iron removal ability. When materials pass through, they quickly adsorb the ferromagnetic impurities contained therein and carry these impurities to a non-magnetic area through the rotation of the belt.
[0003] However, during the use of the magnetic separator body, when the ferromagnetic impurities adsorbed by the magnetic separator body move from the magnetic area to the non-magnetic area, the ferromagnetic impurities will fall instantly when they lose magnetic attraction, and the falling trajectory will be affected by the movement of the iron unloading belt on the magnetic separator body. Because the sizes of the ferromagnetic impurities are different, the inertia sizes of the ferromagnetic impurities when falling are not the same. When the ferromagnetic impurities are thrown out with a greater force, the ferromagnetic impurities will hit the surrounding equipment or workers, which will cause certain harm to the surrounding workers. Moreover, the ferromagnetic impurities sometimes adsorb on the iron unloading belt and move along with the iron unloading belt, being thrown out and falling from time to time, which will cause the throwing direction and range of the ferromagnetic impurities to be wider, have a greater impact on the surrounding environment, and cause harm to the health of the surrounding workers. When there are more ferromagnetic impurities, the impact on the surrounding environment and people is greater.
[0004] Based on the above situation, it is necessary to design a sealing device for the magnetic separator to solve the above problems. Summary of the Utility Model

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.
[0026] Refer to Figures 1-8As shown, the sealing device of the iron remover includes the iron remover body 1. The iron remover body 1 includes a fixed frame 100, a roller 101 connected to the fixed frame 100, and an iron unloading belt 102 sleeved on the roller 101. The sizes of the rollers 101 vary according to actual usage requirements, but their main functions and capabilities are the same, which is to drive the movement of the iron unloading belt 102.
[0027] The iron remover body 1 is a structure of the prior art. The iron remover body 1 further includes an iron remover magnetic part 103 fixedly installed on the frame, a power part 104 fixedly installed on the frame, and a scraper 105 fixedly connected to the surface of the iron unloading belt 102. The frame and the roller 101 support the iron remover magnetic part 103 and the iron unloading belt 102. The power part 104 is a structure of the prior art, mainly to provide power for the operation of the iron remover body 1. When the iron remover body 1 is in use, the iron remover body 1 is first placed above a transport belt (not shown in the figure) for transporting materials, and the iron unloading belt 102 on the iron remover body 1 is perpendicular to the transport belt. The iron remover magnetic part 103 is located directly above the transport belt. Then, the power is turned on, and the iron remover body 1 starts to work. After the iron remover magnetic part 103 on the iron remover body 1 is powered on, it will generate a certain magnetic force according to its own physical structure. Then, the magnetic attraction force on the iron remover magnetic part 103 passes through the iron unloading belt 102 to adsorb ferromagnetic impurities on the transport belt. Then, the ferromagnetic impurities will be adsorbed on the iron unloading belt 102. The iron unloading belt 102 will rotate continuously driven by the roller 101, and the adsorbed ferromagnetic impurities will move from a position closer to the iron remover magnetic part 103 to a position farther from the iron remover magnetic part 103, that is, move the ferromagnetic impurities from the magnetic area to the non-magnetic area. At this time, after the ferromagnetic impurities leave the magnetic adsorption range of the iron remover magnetic part 103, they will be thrown out due to the inertia when the iron unloading belt 102 moves. In this cycle, the iron remover body 1 continuously adsorbs and removes ferromagnetic impurities in the materials passing under the iron remover magnetic part 103. In the prior art structure, a collection box (not shown in the figure) for collecting ferromagnetic impurities is provided below the iron remover body 1. However, ferromagnetic impurities with large inertia will still be thrown out of the collection box, or ferromagnetic impurities adsorbed on the iron unloading belt 102 and moving with the iron unloading belt 102 will be thrown out irregularly and may not necessarily fall into the collection box, which will cause impacts and injuries to surrounding workers or equipment.
[0028] To prevent ferromagnetic impurities on the iron-unloading belt 102 from being randomly thrown out and uncontrollably, a sealing box 2 is provided on the fixed frame 100 of the iron remover body 1. The sealing box 2 is sleeved on one end of the iron remover body 1 that throws out ferromagnetic impurities. The sealing box 2 is used to collect the thrown-out ferromagnetic impurities. The sealing box 2 completely covers one end of the iron remover. When the ferromagnetic impurities are within the range covered by the driving sealing box 2, no matter how the ferromagnetic impurities are thrown out, they will eventually be collected in the sealing box 2 and cannot disperse in all directions. In order to enable the sealing box 2 to cover the adsorbed ferromagnetic impurities earlier, an extension mechanism 3 is provided at the input end of the sealing box 2. The extension mechanism 3 controls the coverage range of the input end of the sealing box 2. The extension mechanism 3 is an adjustable mechanism, which is convenient to adjust the length according to the actual use situation. The extension mechanism 3 can incorporate the ferromagnetic impurities into the sealing box 2 earlier. Even if the ferromagnetic impurities fall off when adsorbed, under the action of the extension mechanism 3, they will eventually fall into the sealing box 2. Some ferromagnetic impurities will still stick to the iron-unloading belt 102 after losing the magnetic attraction of the iron remover magnetic component 103. Therefore, in order to prevent the ferromagnetic impurities on the iron-unloading belt 102 from being thrown out of the area outside the sealing box 2, a cleaning component 4 for removing the attachments on the surface of the iron-unloading belt 102 is provided inside the sealing box 2.
[0029] Among them, as shown in Figure 5 The extension mechanism 3 is composed of a U-shaped movable plate 301 and a U-shaped fixed plate 302. The fixed plate 302 is fixedly connected to the input end of the sealing box 2. The movable plate 301 is slidably connected to the fixed plate 302. A number of positioning holes 303 are provided on both the movable plate 301 and the fixed plate 302. The positioning holes 303 on the movable plate 301 correspond to the positioning holes 303 on the fixed plate 302 and are movably inserted with fixing pins 304. During use, by moving the movable plate 301 to slide on the fixed plate 302, the position of the input end of the sealing box 2 can be adjusted. Since both the movable plate 301 and the fixed plate 302 are U-shaped, it can better restrain and collect the ferromagnetic impurities on the iron-unloading belt 102. The setting of the positioning holes 303 and the fixing pins 304 is to better fix the positional relationship between the movable plate 301 and the fixed plate 302. After moving the movable plate 301, the positioning holes 303 at appropriate positions on the movable plate 301 are docked with the positioning holes 303 at appropriate positions on the fixed plate 302. Then, the fixing pins 304 are inserted through the two relatively docked positioning holes 303 at appropriate positions. At this time, the positional relationship between the fixed plate 302 and the movable plate 301 is fixed.
[0030] As shown in Figures 4-8As shown in the figure, the cleaning component 4 includes sliding frames 5 located on both sides inside the sealed box 2, brush rollers 6 rotatably connected to the sliding frames 5, and a driving component 7 for driving the rotation of the brush rollers 6. The sliding frame 5 includes a first device frame 501 and a second device frame 502. The brush roller 6 is rotatably connected to the first device frame 501. The first device frame 501 is slidably connected to the second device frame 502. The surface of the brush roller 6 corresponds to the surface of the iron unloading belt 102. When the driving component 7 drives the brush roller 6 to rotate, ferromagnetic impurities on the iron unloading belt 102 can be swept away when the brush roller 6 contacts the iron unloading belt 102, achieving the purpose of cleaning.
[0031] During this process, in order to prevent the ferromagnetic impurities on the iron unloading belt 102 from being driven by the brush roller 6 to be thrown out over a large range, a partition tile 12 is provided at one end of the brush roller 6 away from the iron unloading belt 102.
[0032] Specifically, the driving component 7 includes a driven pulley 703 fixedly connected to one end of the brush roller 6, a driving pulley 702 rotatably connected to the sliding frame 5, a transmission belt 704 sleeved on the driving pulley 702 and the driven pulley 703, and a motor 701 installed on the sliding frame 5. The output end of the motor 701 is connected to the driving pulley 702. When the motor 701 operates, it drives the driving pulley 702 to rotate, and then drives the driven pulley 703 to rotate through the transmission belt 704, and the driven pulley 703 drives the brush roller 6 to rotate. In order to prevent the ferromagnetic impurities lifted by the brush roller 6 during rotation from affecting the motor 701, the motor 701 is located at a position behind the partition tile.
[0033] Furthermore, the cleaning component 4 further includes track plates 9 fixedly connected to the inner walls on both sides of the sealed box 2 and telescopic rods 8 fixedly connected to the track plates 9. The sliding frame 5 is slidably connected to the track plates 9. The movable end of the telescopic rod 8 is fixedly connected to the sliding frame 5. Since a scraper 105 is provided on the iron unloading belt 102, and the scraper 105 has a protective effect on the iron unloading belt 102, and the scraper 105 is a mature existing technical structure. Since the brush roller 6 needs to avoid the presence of the scraper 105 when contacting the iron unloading belt 102, the sliding frame 5 connecting the brush roller 6 is slidably connected to the track plates 9. Then, under the action of the movement of the movable end of the telescopic rod 8, the sliding frame 5 can be moved, and thus the brush roller 6 can be moved. When the scraper 105 moves in front of the brush roller 6, the brush roller 6 can be moved backward in time to avoid the collision of the scraper 105 with the brush roller 6.
[0034] When the iron unloading belt 102 is in use, due to its material, the surface of the iron unloading belt 102 is not always flat during operation and there will be undulations. Therefore, in order to better apply the brush roller 6 to remove ferromagnetic impurities on the iron unloading belt 102, a spring 13 is fixedly connected between the device frame one 501 and the device frame two 502. When the device frame one 501 rotatably connected to the brush roller 6 is in use, it is not in a fixed position. Affected by the spring 13, the device frame one 501 will move at a certain position on the device frame two 502, where the device frame two 502 is connected to the movable end of the telescopic rod 8.
[0035] Furthermore, referring to Figure 4 As shown, a controller 10 is provided on the sealed box 2. The controller 10 is electrically connected to the telescopic rod 8. The main purpose of setting the controller 10 is to better control the brush roller 6 to avoid the scraper 105. Since the scrapers 105 are evenly and equidistantly arranged on the iron unloading belt 102, the encounter time between each scraper 105 and the brush roller 6 is the same. Under the control of the controller 10 to operate the telescopic rod 8, the brush roller 6 is retracted every fixed time to avoid the scraper 105.
[0036] Referring to Figure 2 and Figure 4 As shown, since the fixed installation of the sealed box 2 is relatively cumbersome, in order to facilitate the cleaning of the inside of the sealed box 2, a collecting box 11 is communicated with the sealed box 2, and the collecting box 11 is movably clamped to the sealed box 2. The ferromagnetic impurities inside the sealed box 2 will fall into the collecting box 11. The installation and disassembly of the collecting box 11 are convenient. Therefore, after the ferromagnetic impurities are accumulated to a certain extent each time, the collecting box 11 can be removed for cleaning.
