An apparatus for the beneficiation of ilmenite

Abstract

The application relates to the technical field of ore dressing, and discloses a titanium-iron ore sorting device which comprises a shell, a hollow shaft, a rotating drum, a rotating shaft, a fan-shaped piece, a magnet, a conveyor, a first driving piece and a second driving piece. The first driving piece is controlled to work, so that the hollow shaft and a plurality of permanent magnetic rollers rotate. When the plurality of permanent magnetic rollers rotate, the plurality of conveyors are driven to rotate. When the hollow shaft rotates, the rotating drum is driven to rotate. When screening, part of magnetic metal substances can be attached to the surface of the rotating drum and move with the rotating drum under the magnetic force of the plurality of magnets. Since the positions of the plurality of magnets are unchanged, when the adsorbed magnetic substances are far away from the plurality of magnets, the magnetic substances can automatically fall under the action of gravity. The unadsorbed substances can sequentially fall on the plurality of conveyors below. The gravity and the magnetic force are utilized again to automatically complete the sorting, and compared with the scraping mode, the abrasion and damage can be avoided. Moreover, the raw materials can be sorted for multiple times, and the sorting effect is ensured.

Description

Technical Field

[0001] This application relates to the field of mineral processing technology, for example to an apparatus for separating ilmenite. Background Technology

[0002] A related technology (Announcement No.: CN221085953U) discloses an ilmenite sorting device, including a sorting box, scrapers and inclined plates symmetrically fixedly connected to the inner walls of both sides of the sorting box, and rotating shafts one and two rotatably connected inside the sorting box. The inclined plates are located below the scrapers. Discharge troughs one is provided on both outer walls of the middle part of the sorting box, corresponding to the inclined plates. Discharge troughs two are provided on both outer walls near the bottom of the sorting box. Gears are fixedly connected to one end of rotating shafts one and two through the outer wall of the sorting box, and the two gears mesh together. Magnetic cylinders are fixedly sleeved on both rotating shafts one and two, and the magnetic cylinders are in contact with the scrapers. The sorting box is provided with a drive assembly for driving rotating shafts one and two to rotate intermittently and synchronously in opposite directions.

[0003] In implementing the above embodiments, at least the following problems were found in the related technology:

[0004] This ilmenite sorting device uses a drive assembly to intermittently rotate a magnetic cylinder, allowing the scraper to remove magnetic metal substances adsorbed on the cylinder's surface. This prevents excessive magnetic metal adsorption on the cylinder's surface, which could negatively impact the sorting efficiency of the ilmenite raw material. However, because the magnetic cylinder and scraper are in close contact, wear and tear will inevitably occur between them over time, creating gaps and hindering the smooth operation of the ilmenite sorting process.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0008] In some embodiments, the ilmenite sorting device includes: a housing; a hollow shaft, rectangular along the width of the housing, rotatably passing through the side wall of the housing; a rotating drum, mounted on the outer wall of the hollow shaft, coaxially distributed with the hollow shaft, and located inside the housing; a rotating shaft, rotatably passing through the hollow shaft, coaxially distributed with the hollow shaft; a sector-shaped component, mounted on the rotating shaft, and located inside the rotating drum, the centerline of the sector-shaped component coinciding with the axis of the hollow shaft; magnets, uniformly mounted on the arc-shaped surface of the sector-shaped component; and a conveyor, located inside the housing, extending along the height direction of the housing from top to bottom. The following components are arranged sequentially below the rotating drum, along the length of the housing from left to right, and all located on the right side of the rotating drum. Each conveyor includes a permanent magnet roller and a conveyor roller rotatably mounted on the side wall of the housing, and a conveyor belt fitted onto the permanent magnet roller and the conveyor roller. A first driving member is installed between the outer wall of the housing and the hollow shaft and the plurality of permanent magnet rollers, and is configured to drive the hollow shaft and the plurality of permanent magnet rollers to rotate relative to the housing. A second driving member is installed between the outer wall of the housing and the rotating shaft, and is configured to drive the rotating shaft to rotate relative to the housing.

[0009] Optionally, the first driving component includes: driven pulleys, respectively mounted on the outer wall of the hollow shaft and each of the permanent magnet rollers, and all located outside the housing; a first belt, respectively fitted between two adjacent driven pulleys; wherein the hollow shaft can be rotated in a controlled manner to make the multiple permanent magnet rollers rotate synchronously.

[0010] Optionally, the first driving component further includes: a support rod, mounted on the outer wall of the housing; a mounting plate, mounted on the end of the support rod; a motor, mounted on the mounting plate, the axis of the rotating end of the motor being parallel to the axis of the hollow shaft; a driving pulley, mounted on the rotating end of the motor; and a second belt, fitted between the driving pulley and the driven pulley on the outer wall of the hollow shaft.

[0011] Optionally, the second driving component includes: a support mounted on the outer wall of the housing; a disc mounted on the rotating shaft and located outside the housing; and an electric push rod rotatably mounted between the support and the disc.

[0012] Optionally, it further includes: a bearing housing, mounted on the outer wall of the housing and sleeved on the hollow shaft; and a first bearing, mounted between the bearing housing and the hollow shaft.

[0013] Optionally, it further includes a second bearing, installed between the hollow shaft and the rotating shaft.

[0014] Optionally, it also includes: mounted bearings, respectively fitted onto each of the permanent magnet rollers and the conveying rollers, and all mounted on the outer wall of the housing.

[0015] Optionally, it also includes: support legs, mounted on the outer wall of the housing, for contacting the ground.

[0016] Optionally, it further includes: a first baffle installed inside the housing and located between two adjacent conveyor belts; and / or a second baffle installed on the inner wall of the housing and located above the rotating drum along the height direction of the housing.

[0017] The ilmenite sorting device provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides an ilmenite sorting device, comprising a housing, a hollow shaft, a rotating drum, a rotating shaft, a sector-shaped component, magnets, a conveyor, a first driving component, and a second driving component. The housing includes a feed inlet at the top and a discharge outlet at the bottom, used for feeding and discharging materials, respectively. The hollow shaft is square along the width of the housing and rotatably passes through the side wall of the housing, allowing it to rotate relative to the side wall. The rotating drum is mounted on the outer wall of the hollow shaft, coaxially distributed with the hollow shaft, and located inside the housing, rotating under the drive of the hollow shaft. The rotating shaft rotatably passes through the hollow shaft, coaxially distributed with the hollow shaft, and rotating relative to the side wall of the housing. The sector-shaped component is mounted on the rotating shaft and located inside the rotating drum, rotating inside the rotating drum under the drive of the rotating shaft, with its centerline coinciding with the axis of the hollow shaft. Magnets are uniformly mounted on the arc-shaped surface of the sector-shaped component to provide magnetic force. The conveyor is located inside the housing and is used to transport materials. The components are distributed sequentially from top to bottom along the height of the housing, all located below the rotating drum. Along the length of the housing, they are distributed sequentially from left to right, all located to the right of the rotating drum. This arrangement ensures that material passing through the rotating drum falls onto the uppermost conveyor belt, and that material falling onto the uppermost conveyor belt subsequently falls onto multiple lower conveyor belts. Each conveyor includes a rotatable permanent magnet roller and a conveyor roller mounted on the side wall of the housing, and a conveyor belt fitted onto the permanent magnet roller and the conveyor roller. The permanent magnet roller and the conveyor roller together support the conveyor belt, causing it to rotate continuously along a specific trajectory. The permanent magnet roller also provides magnetic force. A first drive unit is installed between the outer wall of the housing and the hollow shaft and multiple permanent magnet rollers, providing driving force to rotate the hollow shaft and multiple permanent magnet rollers relative to the housing. A second drive unit is installed between the outer wall of the housing and the rotating shaft, providing driving force to rotate the rotating shaft relative to the housing.

[0019] In operation, controlling the first drive component causes the hollow shaft and multiple permanent magnet rollers to rotate. The rotation of the hollow shaft drives the rotating drum. The rotation of the permanent magnet rollers drives multiple conveyor belts. During screening, under the magnetic force of the multiple magnets, some magnetic metallic substances adhere to the surface of the rotating drum and move with it. Since the positions of the magnets remain constant, when the attracted magnetic material is far from the magnets, it will automatically fall off under gravity. The unattracted material falls onto the uppermost conveyor belt and is transported. When it reaches the uppermost permanent magnet roller, the remaining magnetic material adheres to the surface of the uppermost conveyor belt under the magnetic force of the roller and moves with it. Since the position of the uppermost permanent magnet roller remains constant, when the attracted magnetic material is far from the uppermost permanent magnet roller, it will automatically fall off under gravity. The unattracted material falls onto the adjacent lower conveyor belt, and so on, until multiple sorting operations are completed. Utilizing gravity and magnetism, the sorting process is automated, avoiding wear and damage compared to scraping methods. Furthermore, it can perform multiple sorting operations to ensure optimal results. Controlling the second drive unit rotates the shaft, which in turn rotates the fan-shaped components. This ultimately drives multiple magnets to rotate, and the initial positions and angles of these magnets can be adjusted to adapt to different sorting conditions.

[0036] Combination Figures 1 to 4 As shown, this disclosure provides an ilmenite sorting device, including a housing 1, a hollow shaft 2, a rotating drum 3, a rotating shaft 4, a sector-shaped component 5, a magnet 6, a conveyor, a first driving component, and a second driving component. The housing 1 includes a feed inlet at the top and a discharge outlet at the bottom, used for feeding and discharging materials, respectively. The hollow shaft 2 is square along the width of the housing 1 and rotatably passes through the side wall of the housing 1, allowing it to rotate relative to the side wall. The rotating drum 3 is mounted on the outer wall of the hollow shaft 2, coaxially distributed with the hollow shaft 2, and located inside the housing 1, rotating under the drive of the hollow shaft 2. The rotating shaft 4 is rotatably passed through the hollow shaft 2, coaxially distributed with the hollow shaft 2, and rotating relative to the side wall of the housing 1. The sector-shaped component 5 is mounted on the rotating shaft 4 and located inside the rotating drum 3, rotating inside the rotating drum 3 under the drive of the rotating shaft 4, with the center line of the sector-shaped component 5 coinciding with the axis of the hollow shaft 2. Magnets 6 are evenly installed on the arc-shaped surface of the sector member 5 to provide magnetic force. Conveyors are located inside the housing 1 and are used to transport materials. They are distributed sequentially from top to bottom along the height direction of the housing 1, all located below the rotating drum 3, and sequentially distributed from left to right along the length direction of the housing 1, all located to the right of the rotating drum 3. This allows materials passing through the rotating drum 3 to fall onto the uppermost conveyor belt 9, and materials falling onto the uppermost conveyor belt 9 can then sequentially fall onto multiple lower conveyor belts 9. Each conveyor includes a rotatable permanent magnet roller 7 and a conveyor roller 8 mounted on the side wall of the housing 1, and a conveyor belt 9 fitted onto the permanent magnet roller 7 and the conveyor roller 8. The permanent magnet roller 7 and the conveyor roller 8 together support the conveyor belt 9, causing the conveyor belt 9 to rotate continuously along a specific trajectory. The permanent magnet roller 7 also provides magnetic force. A first driving member is installed between the outer wall of the housing 1 and the hollow shaft 2 and multiple permanent magnet rollers 7 to provide driving force, driving the hollow shaft 2 and multiple permanent magnet rollers 7 to rotate relative to the housing 1. The second driving component is installed between the outer wall of the housing 1 and the rotating shaft 4 to provide driving force and drive the rotating shaft 4 to rotate relative to the housing 1.

[0037] This embodiment of the invention provides an ilmenite sorting device. By controlling the operation of a first driving component, a hollow shaft 2 and multiple permanent magnet rollers 7 can be rotated. When the hollow shaft 2 rotates, it drives a rotating drum 3 to rotate. When the multiple permanent magnet rollers 7 rotate, they drive multiple conveyor belts 9 to rotate. During screening, under the magnetic force of the multiple magnets 6, some magnetic metallic substances can adhere to the surface of the rotating drum 3 and move with it. Since the positions of the multiple magnets 6 remain unchanged, when the adsorbed magnetic substances are far from the multiple magnets 6, they can automatically fall off under the action of gravity. The unadsorbed substances can fall onto the uppermost conveyor belt 9 and be transported. When transported to the uppermost permanent magnet roller 7, under the magnetic force of the permanent magnet roller 7, the remaining magnetic substances can adhere to the surface of the uppermost conveyor belt 9 and move with it. Since the position of the uppermost permanent magnet roller 7 remains unchanged, when the adsorbed magnetic substances are far from the uppermost permanent magnet roller 7, they can automatically fall off under the action of gravity. Unadsorbed material falls onto the adjacent lower conveyor belt 9, and the sorting process is repeated multiple times. Utilizing gravity and magnetism, the sorting is completed automatically, avoiding wear and damage compared to scraping methods. Furthermore, it allows for multiple sorting of raw materials, ensuring optimal sorting results. Controlling the second drive unit rotates the rotating shaft 4, which in turn rotates the fan-shaped component 5. This ultimately rotates multiple magnets 6, and the initial position and angle of the magnets 6 can be adjusted to adapt to different sorting conditions.

[0038] Optionally, combined Figure 1 and Figure 3 As shown, the first driving component includes a driven pulley 10 and a first belt. The driven pulleys 10 are respectively mounted on the outer wall of the hollow shaft 2 and each permanent magnet roller 7, and are all located outside the housing 1, rotating synchronously with the hollow shaft 2 and the multiple permanent magnet rollers 7. The first belt is respectively fitted between two adjacent driven pulleys 10, and is used to transmit driving force. The hollow shaft 2 can be controlled to rotate, so that the multiple permanent magnet rollers 7 rotate synchronously.

[0039] In this embodiment, when the hollow shaft 2 rotates under the drive of an external force, it drives the driven pulley 10 on it to rotate. Through multiple first belts, the remaining driven pulleys can be driven to rotate, thereby driving multiple permanent magnet rollers 7 to rotate. By using a single drive source, the hollow shaft 2 and multiple permanent magnet rollers 7 can rotate simultaneously, reducing the number of drive sources and saving costs.

[0040] Optionally, combined Figure 3As shown, the first driving component also includes a support rod 11, a mounting plate 12, a motor 13, a drive pulley 14, and a second belt. The support rod 11 is mounted on the outer wall of the housing 1 to support the mounting plate 12. The mounting plate 12 is mounted on the end of the support rod 11 to support the motor 13. The motor 13 is mounted on the mounting plate 12, and the axis of the rotating end of the motor 13 is parallel to the axis of the hollow shaft 2, providing driving force. The drive pulley 14 is mounted on the rotating end of the motor 13 and rotates under the drive of the motor 13. The second belt is fitted between the drive pulley 14 and the driven pulley 10 on the outer wall of the hollow shaft 2 to transmit driving force.

[0041] In this embodiment, controlling the motor 13 to operate drives the drive pulley 14 to rotate. The second belt then drives the adjacent driven pulley 10 to rotate. Multiple first belts then drive the remaining driven pulleys 10 to rotate. This ultimately achieves the simultaneous rotation of the hollow shaft 2 and multiple permanent magnet rollers 7.

[0042] Optionally, combined Figure 1 and Figure 3 As shown, the second driving component includes a support 15, a disk 16, and an electric actuator 17. The support 15 is mounted on the outer wall of the housing 1 to support the rotatable electric actuator 17. The disk 16 is mounted on the rotating shaft 4 and located outside the housing 1, also to support the rotatable electric actuator 17. The electric actuator 17 is rotatably mounted between the support 15 and the disk 16, and can rotate relative to both the support 15 and the disk 16 to provide driving force.

[0043] In this embodiment, the electric push rod 17 is controlled to operate, and under the support of the support 15, the disc 16 drives the rotating shaft 4 to rotate. This, in turn, drives the sector component 5 to rotate, and ultimately drives the multiple magnets 6 to rotate. The initial position angle of the multiple magnets 6 is adjusted to adapt to different sorting conditions.

[0044] Optionally, combined Figure 3 and Figure 4 As shown, it also includes a bearing housing 18 and a first bearing 19. The bearing housing 18 is mounted on the outer wall of the housing 1 and sleeved on the hollow shaft 2. The first bearing 19 is mounted between the bearing housing 18 and the hollow shaft 2.

[0045] In this embodiment, the bearing housing 18 is mounted on the outer wall of the housing 1 to support the mounting of the first bearing 19. The first bearing 19 is used to support the mounting of the rotatable hollow shaft 2, reduce the frictional force on the hollow shaft 2, and improve the accuracy of the hollow shaft 2 during rotation.

[0046] Optionally, combined Figure 3 and Figure 4 As shown, it also includes a second bearing 20. The second bearing 20 is installed between the hollow shaft 2 and the rotating shaft 4.

[0047] In this embodiment, a second bearing 20 is further installed between the hollow shaft 2 and the rotating shaft 4. The second bearing 20 is used to reduce the friction between the hollow shaft 2 and the rotating shaft 4 and to improve the accuracy of the hollow shaft 2 during rotation.

[0048] Optionally, combined Figure 1 As shown, it also includes a mounted bearing 21. The mounted bearing 21 is respectively fitted onto each permanent magnet roller 7 and conveyor roller 8, and is installed on the outer wall of the housing 1.

[0049] In this embodiment, a seated bearing 21 is also included, which is respectively fitted onto each permanent magnet roller 7 and conveyor roller 8 and mounted on the outer wall of the housing 1. The seated bearing 21 is used to reduce the friction between the multiple permanent magnet rollers 7 and conveyor roller 8 and the housing 1, and to improve the accuracy of the multiple permanent magnet rollers 7 and conveyor roller 8 when rotating.

[0050] Optionally, combined Figure 1 and Figure 2 As shown, it also includes support legs 22. Support legs 22 are mounted on the outer wall of the housing 1 and are used to abut against the ground.

[0051] In this embodiment, a support leg 22 is also included, mounted on the outer wall of the housing 1. The support leg 22 is used to abut against the ground, thereby supporting the entire device. This allows the discharge port to be detached from the ground, facilitating the collection of magnetic metal raw materials discharged from the left side and non-magnetic metal raw materials discharged from the right side.

[0052] Optionally, as shown in Figure 2, a first baffle 23 is also included. The first baffle 23 is installed inside the housing 1 and is located between two adjacent conveyor belts 9.

[0053] In this embodiment, a first baffle 23 is also included, which is installed inside the housing 1 and located between two adjacent conveyor belts 9. The first baffle 23 serves to guide the material from the upper conveyor belt 9 to fall onto the adjacent lower conveyor belt 9.

[0054] Optionally, as shown in Figure 2, a second baffle 24 is also included. The second baffle 24 is installed on the inner wall of the housing 1 and is located above the rotating cylinder 3 along the height direction of the housing 1.

[0055] In this embodiment, a second baffle 24 is also installed on the inner wall of the housing 1. The second baffle 24 is located above the rotating cylinder 3 in the height direction of the housing 1, and serves to guide the raw materials added from the feeding port to fall into the cylinder.
