DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0022] As shown in Figure 1 , Figure 3 , Figure 5 The present application provides an ore conveying type iron removal device, which comprises a sorting shell 2, the top of the sorting shell 2 is provided with a feeding inlet 11, and the bottom of the sorting shell 2 is respectively provided with a tailing outlet 8 and a concentrate outlet 9. A roller 3 is arranged inside the sorting shell 2, a magnetic system body 4 is arranged at the position of the inner side wall of the roller 3, a fixed shaft 5 is connected to the magnetic system body 4, the fixed shaft 5 penetrates the roller 3 and the sorting shell 2 in sequence and is fixed outside the sorting shell 2, a swing frame 12 is arranged on the outer wall of the roller 3 along the length direction of the roller 3, there is a gap between the swing frame 12 and the outer wall of the roller 3, and the swing frame 12 can be driven to reciprocate along the outer wall of the roller 3 opposite to the region of the magnetic system body 4. The roller 3 can be driven to rotate the ore raw material to the direction close to the magnetic system body 4. The concentrate outlet 9 is arranged below the side of the roller 3 opposite to the magnetic system body 4, and the tailing outlet 8 is arranged below the side of the roller 3 away from the magnetic system body 4.

[0023] The magnetic system body 4 in the present application is arranged on one side of the roller 3 and does not rotate with the roller 3. After the ore raw material falls to the top of the roller 3 from the feeding port 11, it rotates with the roller 3 towards the magnetic system body 4. During the rotation, part of the iron impurities is adsorbed on the surface of the roller 3, and part of the ore is discharged from the gap between the roller 3 and the swing frame 12. The remaining iron impurities and ore fall into the swing frame 12 and move to the top of the magnetic system body 4, and then fall from the swing frame 12 to the roller 3 again. The roller 3 continues to drive the rotation, and the magnetic system body 4 continues to adsorb the remaining iron impurities. The magnetic separation is repeated as many times as possible to remove the iron impurities in the ore raw material.

[0024] The ore raw material rotates to the side of the magnetic system body 4, and the iron impurities are adsorbed on the roller 3. The ore falls into the concentrate port 9 because it does not have magnetic attraction. The iron impurities lose the magnetic attraction when rotating away from the magnetic system body 4 and fall into the tailing port 8. The iron impurities and the ore can only be separated on one side of the magnetic system body 4. Therefore, the concentrate port 9 is arranged below the side of the roller 3 opposite to the magnetic system body 4 to receive the ore that is not magnetically attracted. The tailing port 8 is arranged below the side of the roller 3 away from the magnetic system body 4 to receive the iron impurities that lose the magnetic attraction of the magnetic system body 4. After the separation by the magnetic system body 4, the iron impurities in the ore raw material are discharged from the tailing port 8, and the ore is discharged from the concentrate port 9.

[0025] The gap distance between the swing frame 12 and the roller 3 is close to the position of the magnetic system body 4, so it is also within the magnetic attraction range of the magnetic system body 4. During the discharge of the ore from the gap, the iron impurities mixed in the ore can be instantly adsorbed on the outer wall of the roller 3 by the magnetic system body 4, thereby reducing the iron impurities in the ore as much as possible and ensuring the iron removal effect.

[0026] The swing frame 12 reciprocates on the outer wall of the area of the roller 3 opposite to the magnetic system body 4 to re-pour the received ore raw material to the outer wall of the roller 3 opposite to the magnetic system body 4 for re-magnetic separation. In order to better re-magnetic separate the ore raw material, one side of the magnetic system body 4 is located close to the top of the roller 3, and the other side is located close to the bottom of the roller 3. The swing frame 12 can receive ore raw material during upward and downward swinging. When the swing frame 12 swings to the top of the magnetic system body 4, the bottom plate of the swing frame 12 receiving the ore raw material is in a vertical state, and the ore raw material inside can be completely poured to the outer wall of the roller 3 under the action of gravity.

[0027] As Figure 2 , Figure 3As shown, if the ore raw materials are continuously fed into the feeding port 11, the swing frame 12 may be difficult to swing due to the excessive weight of the received ore raw materials. In order to reduce the amount of ore raw materials fed into the feeding port 11 at one time as much as possible, the present application is designed to adopt an intermittent feeding mode, and a feeding bin 15 is formed on the sorting shell 2 near the position below the feeding port 11. The feeding bin 15 is provided with a rotating rod 6, and a plurality of partition plates 7 are arranged in a circular array along the length direction of the rotating rod 6. The rotating rod 6 can rotate, and the ore raw materials fall between two partition plates 7 after entering from the feeding port 11. Under the driving of the rotating rod 6, the partition plates 7 rotate and drive the ore raw materials to be fed. The continuous rotation of the rotating rod 6 and the partition plates 7 enables the ore raw materials to first fall between the two partition plates 7 after entering from the feeding port 11, and then the ore raw materials fall to the top of the roller 3 under the action of gravity when they rotate to the lower position. This intermittent feeding mode enables the ore raw materials on the swing frame 12 not to be too heavy, and also enables the iron impurities to be well magnetically separated.

[0028] As shown in the figure, Figure 1 The ore raw materials fall from the two partition plates 7 to the roller 3, and then rotate with the roller 3. If the rotating rod 6 and the roller 3 are driven by independent structures, more ore raw materials will be fed to the roller 3 when the rotating rod 6 accelerates. In order to quickly magnetically separate the ore raw materials, the roller 3 also needs to accelerate. The independent driving structure makes the rotating rod 6 and the roller 3 unable to work in complete synchronization. In order to enable the rotating rod 6 and the roller 3 to work cooperatively, the present application is designed as follows. Specifically, a transmission structure 14 is arranged outside the sorting shell 2, and the transmission structure 14 can drive the rotating rod 6 and the roller 3 to rotate.

[0029] The transmission structure 14 includes a small pulley 1401 arranged at the end of the rotating rod 6, a large pulley 1402 arranged at the end of the roller 3, a first driving motor 1403, a first output wheel 1404 and a second output wheel 1405 installed in sequence at the output end of the first driving motor 1403, a first transmission belt 1406 sleeved in sequence on the small pulley 1401 and the first output wheel 1404, and a second transmission belt 1407 sleeved in sequence on the large pulley 1402 and the second output wheel 1405. The end of the rotating rod 6 penetrates through the feeding bin 15 and is connected with the small pulley 1401. The end of the roller 3 is provided with a rotating shaft, and the rotating shaft penetrates through the sorting shell 2 and is connected with the large pulley 1402. The first driving motor 1403 drives the first output wheel 1404 and the second output wheel 1405 to rotate. The first output wheel 1404 drives the first transmission belt 1406 and the small pulley 1401 to rotate, and the small pulley 1401 drives the rotating rod 6 to rotate. The second output wheel 1405 drives the second transmission belt 1407 and the large pulley 1402 to rotate, and the large pulley 1402 drives the rotating shaft and the roller 3 to rotate.

[0030] The first driving motor 1403 is designed to drive the rotating rod 6 and the roller 3 to rotate at the same time, so that the rotating rod 6 and the roller 3 can better realize the feeding and collecting of the ore.

[0031] As shown in Figure 3 , Figure 7 , in order to drive the swing frame 12 to swing, the driving structure 13 is installed outside the sorting shell 2, and the driving structure 13 can drive the swing frame 12 to move.

[0032] The driving structure 13 comprises a disc shell 1301 coaxially installed at the end of the roller 3, a large driving wheel 1302 coaxially installed on the side of the disc shell 1301 away from the roller 3, a second driving motor 1303, a small driving wheel 1304 installed at the output end of the second driving motor 1303, and a driving belt 1305 sequentially sleeved on the large driving wheel 1302 and the small driving wheel 1304. The disc shell 1301 is connected to the end of the swing frame 12, and a connecting shaft is installed on the disc shell 1301. The connecting shaft penetrates the sorting shell 2 and is connected with the large driving wheel 1302. The second driving motor 1303 drives the small driving wheel 1304 to reciprocate, the small driving wheel 1304 drives the driving belt 1305 and the large belt wheel 1402 to reciprocate, the large belt wheel 1402 drives the connecting shaft and the disc shell 1301 to reciprocate, and the disc shell 1301 drives the swing frame 12 to reciprocate.

[0033] In order to ensure the stability of the swing of the swing frame 12, disc shells 1301 are installed at both ends of the roller 3, and the two disc shells 1301 are connected to both ends of the swing frame 12, respectively.

[0034] The first driving motor 1403 and the second driving motor 1303 are installed on both sides of the rack 1, respectively, so as to avoid the mutual interference of the driving devices when the driving devices on one side of the rack 1 are operated.

[0035] As shown in Figure 5 , Figure 6 , in order to loosen the ore raw materials on the swing frame 12, a plurality of rotating rollers 16 are arranged along the length direction of the swing frame 12, and driven gears 17 are installed at the ends of the rotating rollers 16. The driven gears 17 are meshed with each other, and a driving gear 18 is coaxially installed on the side of one of the driven gears 17 away from the rotating roller 16.

[0036] As shown in Figure 8 , Figure 9As shown, the end of the roller 3 is provided with an oval wheel 19, the side of the oval wheel 19 is slidably connected with a sliding rod 20, the bottom of the sliding rod 20 is provided with a rectangular tooth 21, the side wall of the sliding rod 20 is fixedly connected with an extension rod 22, the extension rod 22 is provided with a reset spring 23, the swing frame 12 is provided with a limiting rod 24, and the end of the sliding rod 20 and the extension rod 22 away from the oval wheel 19 is slidably connected through the limiting rod 24.

[0037] The rectangular tooth 21 is engaged with the driving gear 18.

[0038] The roller 3 drives the rotation of the oval wheel 19, when the long axis end of the oval wheel 19 rotates to approach the sliding rod 20, the oval wheel 19 drives the sliding rod 20 to slide, the sliding rod 20 drives the rectangular tooth 21 and the extension rod 22 to slide, the rectangular tooth 21 drives the driving gear 18 to rotate, the driving gear 18 drives the connected driven gear 17 to rotate, the driven gear 17 drives the remaining driven gears 17 to rotate, and the rotating rollers 16 are all followed to rotate, and the extension rod 22 presses the reset spring 23.

[0039] When the long axis end of the oval wheel 19 rotates away from the sliding rod 20, the reset spring 23 releases the elastic potential energy and drives the extension rod 22 to slide reversely, the extension rod 22 drives the sliding rod 20 and the rectangular tooth 21 to slide reversely, the rectangular tooth 21 drives the driving gear 18 to rotate reversely, the driving gear 18 drives the connected driven gear 17 to rotate reversely, the driven gear 17 drives the remaining driven gears 17 to rotate reversely, and the rotating rollers 16 are all followed to rotate reversely.

[0040] The multiple rotating rollers 16 on the swing frame 12 are continuously rotated under the driving of the components such as the oval wheel 19, the sliding rod 20, the driving gear 18, the driven gear 17, and the opposite rotating directions of the adjacent two rotating rollers 16 make the ore raw materials falling in the swing frame 12 dispersed under the rotation of the rotating rollers 16, when the swing frame 12 swings to approach the top of the roller 3, the ore raw materials on the swing frame 12 fall into the roller 3 again under the action of the gravity of the ore raw materials, and the continuous swing of the swing frame 12 also avoids the ore raw materials blocking in the gap between the swing frame 12 and the roller 3, so as to facilitate the ore discharging, in order to facilitate the rotation of the rotating rollers 16 following the driven gear 17, the rotating rollers 16 are provided with bearings at the ends away from the driven gear 17, and the rotating rollers 16 are connected to the inner wall of the swing frame 12 through the bearings.

[0041] The end of the sliding rod 20 does not fit the curved surface of the elliptical wheel 19. If the end of the sliding rod 20 directly abuts the elliptical wheel 19, the elliptical wheel 19 will be resisted by the sliding rod 20 when it rotates. In order to minimize the resistance of the elliptical wheel 19 to the movement of the sliding rod 20, a small roller 25 is installed at the end of the sliding rod 20 near the elliptical wheel 19. The small roller 25 has a central axis running through the middle of the small roller 25, and a connecting plate 26 is installed at the end of the central axis. The end of the connecting plate 26 away from the central axis is connected to the sliding rod 20, and the small roller 25 slides around the side wall of the elliptical wheel 19. The sliding rod 20 contacts the elliptical wheel 19 through the small roller 25. The rotation of the elliptical wheel 19 will squeeze and drive the small roller 25 to rotate. The small roller 25 rolls in contact with the elliptical wheel 19, so that the elliptical wheel 19 is not obstructed when it rotates, and the small roller 25 will squeeze the sliding rod 20 to move after being squeezed, so that the elliptical wheel 19 will not be obstructed and can drive the sliding rod 20 to move.

[0042] like Figure 5 As shown, after the ore raw materials fall from the lower hopper 15 onto the roller 3, part of the ore raw materials will fall onto the swing frame 12. Driven by the second drive motor 1303, the swing frame 12 swings back and forth on the outer wall of the roller 3 facing the magnetic system 4. At the same time, the rotation of the roller 3 drives the elliptical wheel 19 to rotate. The elliptical wheel 19 drives the roller 16 to rotate through the sliding rod 20, the driving gear 18, the driven gear 17 and other components. The swinging of the swing frame 12 and the rotation of the roller 16 realize the functions of receiving, turning and dumping materials. When turning the materials, in order to prevent the ore raw materials from being blocked in the gear teeth between the driven gears 17, the driven gear 17 is arranged on the outside of the swing frame 12. Specifically, the end of the roller 16 passes through the side wall of the swing frame 12 and is connected to the driven gear 17.

[0043] In order to further prevent the ore material on the roller 3 from being blocked between the driven gear 17 and between the driving gear 18 and the rectangular teeth 21, an internal space is set between the disc shell 1301 and the roller 3, and the driven gear 17, the driving gear 18, the sliding rod 20, the telescopic rod 22, the elliptical wheel 19 and other components are arranged in the internal space.

[0044] Ore and iron impurities are discharged from the concentrate port 9 and the tailings port 8 respectively. Therefore, the concentrate port 9 and the tailings port 8 at the bottom of the sorting shell 2 need to be away from the ground. In order to keep the concentrate port 9 and the tailings port 8 away from the ground, a frame 1 is provided on the outer wall of the sorting shell 2. The sorting shell 2 is mounted on the frame 1. The frame 1 can lift the sorting shell 2, thereby keeping the concentrate port 9 and the tailings port 8 away from the ground. At the same time, the first drive motor 1403 and the second drive motor 1303 can also be installed on both sides of the frame 1 respectively.

[0045] The fixed shaft 5 is fixedly installed outside the sorting shell 2 for fixing the magnetic system body 4, so that the magnetic system body 4 does not rotate with the roller 3. In order to fix both ends of the fixed shaft 5, the mounting block 27 is installed on the rack 1, and the end of the fixed shaft 5 is connected to the mounting block 27, that is, the fixed shaft 5 penetrates the roller 3, the oval wheel 19, the disc shell 1301 and the sorting shell 2 in sequence and is connected to the mounting block 27, and the fixed shaft 5, the roller 3, the oval wheel 19 and the disc shell 1301 are coaxially connected.

[0046] As shown in Figure 4 In order to make the sorted iron impurities and ores fall into the tailing port 8 and the concentrate port 9 respectively, the inverted V-shaped guide plate 10 is arranged between the concentrate port 9 and the tailing port 8 in the sorting shell 2, and the two ends of the inverted V-shaped guide plate 10 are fixedly connected with the inner wall of the sorting shell 2. The inverted V-shaped guide plate 10 guides the iron impurities and ores, so that the iron impurities and ores slide to the tailing port 8 and the concentrate port 9 respectively.

[0047] In work, first, the first driving motor 1403 and the second driving motor 1303 are started, and then the ore raw materials are poured into the sorting shell 2 from the feeding port 11.
