Description

Technical Field

[0001] This invention relates to the field of mineral sorting technology, and in particular to an equipment and method for beneficiating ilmenite. Background Technology

[0002] Ilmenite is an oxide mineral containing iron and titanium, and is one of the important ores for refining titanium and iron. Spiral sluice is a device that uses gravity and centrifugal force to separate minerals. Its working principle is based on the difference in movement of mineral particles in the spiral sluice. Its simple and efficient characteristics make it widely used in the mining and mineral processing fields.

[0003] Currently, in the operation of spiral sluices, the equipment is first vertically installed and fixed. The slurry is then fed into the spiral sluice's inlet, with supplementary water added to adjust the slurry concentration. The spiral sluice separates mineral particles through the combined effects of gravity, centrifugal force, and water flow. During the separation process, the slurry on the spiral sluice separates into heavy ore, medium ore, and light ore zones from the inner edge to the outer edge. The heavy ore zone contains heavy particles, the light ore zone contains light particles, and the medium ore zone contains a mixture of heavy and light particles. The separated mineral particles are then discharged through a cut-off device and a receiving hopper. However, the high flow rate and velocity of the medium ore zone during separation result in poor separation of mineral particles in this zone. The existing solution is... The process involves re-sorting the middlings, adding several steps. Secondly, after the heavy mineral particles are separated, they flow downwards in a spiral along the inner edge of the chute. Due to the small radius of rotation at the inner edge and the high friction between the heavy mineral particles and the chute surface, heavy mineral particles accumulate. This accumulation obstructs the flow path of subsequent heavy mineral particles, causing some to flow into the middlings, resulting in mixing and affecting the sorting results. Existing solutions include adding grooves or wedges to the spiral chute, optimizing the distance-to-diameter ratio, or manually cleaning the chute with a hand-held scraper. The former has significant limitations in design and equipment modification, requiring precise matching of mineral characteristics, while the latter is inefficient and cannot address the accumulation problem promptly.

[0004] Therefore, in order to improve the mineral particle separation effect and reduce the accumulation of heavy mineral particles, this invention provides an ilmenite beneficiation equipment and method. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing an ilmenite beneficiation equipment and method.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A beneficiation device for ilmenite includes a beneficiation mechanism. The beneficiation mechanism includes a support frame, a mixing chamber fixedly connected to the top of the support frame, and a spiral groove installed in the middle of the support frame. The upper and lower ends of the spiral groove are the feeding position and the discharging position, respectively. The inner edge and outer edge of the spiral groove are located near the middle of the support frame and away from the middle of the support frame, respectively. A discharge port located above the feeding position is fixedly connected to the mixing chamber.

[0008] The support frame is equipped with a drive mechanism, and the spiral groove and the drive mechanism are jointly equipped with an anti-accumulation mechanism. The drive mechanism is used to drive the anti-accumulation mechanism to rise and fall along the spiral path on the spiral groove. The spiral groove is equipped with multiple separation mechanisms.

[0009] The anti-accumulation mechanism includes a spiral sliding member mounted on the drive mechanism, and a clearing component for preventing the accumulation of heavy mineral particles on the inner edge of the groove is mounted on the spiral sliding member via a support plate; the separation mechanism includes an extension member detachably mounted on the spiral groove, and a separator for separating light mineral particles in the middlings zone is fixedly connected to the extension member; the extension member is provided with a separation component for separating heavy mineral particles in the middlings zone and a scraping component for scraping off mineral particles accumulated between the extension member and the spiral groove.

[0010] In the aforementioned ilmenite beneficiation equipment, the drive mechanism includes a support column, and the support column is fixedly connected to the middle of the support frame. Upper and lower sliding rings are slidably connected to the support column via an electric slider, and a circumferential sliding ring is rotatably connected to the outer ring wall of the upper and lower sliding rings.

[0011] In the aforementioned ilmenite beneficiation equipment, a spiral sliding component is rotatably connected to the outer ring wall of the circumferential sliding ring via a shaft, and the spiral sliding component is slidably connected to the inner edge of the spiral groove. A support plate is fixedly connected to the side of the spiral sliding component away from the circumferential sliding ring.

[0012] In the aforementioned ilmenite beneficiation equipment, the unblocking component includes a connecting plate, and the bottom wall of the support plate is rotatably connected to the connecting plate via a torsion spring rod. One end of the connecting plate is fixedly connected to an unblocking plate, and the other end of the connecting plate is hinged to an unblocking component. The unblocking component consists of a hinge seat connected to the connecting plate and multiple rhomboid components uniformly fixed at the bottom of the hinge seat. The bottom wall of the support plate is fixedly connected to a push rod and a wedge.

[0013] In the aforementioned ilmenite beneficiation equipment, the extension member slows down the flow velocity of the middlings zone by the angle formed between it and the spiral groove. The vertical cross-section of the separator is triangular, and the light mineral particles in the middlings zone flow to the outer edge of the spiral groove through the inclined top wall of the separator.

[0014] In the aforementioned ilmenite beneficiation equipment, the separation component includes a separation plate, and the extension is fixedly connected to the side wall of the separation plate. Multiple wave-shaped grooves for intercepting the middlings are opened vertically through the separation plate, and a discharge plate located below the separation plate is hinged to the extension via a torsion spring rod.

[0015] In the aforementioned ilmenite beneficiation equipment, the projections of the separation plate and the discharge plate in the vertical direction overlap, and the bottom wall of the separation plate and the top wall of the discharge plate are both inclined towards the inner edge of the trough. A wedge block two corresponding to wedge block one is fixedly connected to the side of the discharge plate near the inner edge of the trough.

[0016] In the aforementioned ilmenite beneficiation equipment, the scraping assembly includes a connecting rod. The connecting rod is slidably connected to the inside of the extension via a spring. A rotating adjustment rod corresponding to the push rod is hinged to the side of the connecting rod near the inner edge of the trough via a torsion spring rod. A wedge block is fixedly connected to the side of the connecting rod near the separation plate. The side of the wedge block away from the connecting rod is formed by two inclined surfaces forming an arrow shape.

[0017] In the aforementioned ilmenite beneficiation equipment, the bottom wall of the extension is slidably connected to corresponding wedges five and six via spring two, and a groove for wedges six to overlap is provided in the middle of wedge five. Silicone scrapers are fixedly connected to the bottom walls of wedges five and six, and the side of wedges five and six near wedge three is adapted to the inclined surface of wedge three.

[0018] As a preferred embodiment of the present invention, the present invention also provides a method for beneficiating ilmenite, which is carried out using the aforementioned ilmenite beneficiation equipment, and specifically includes the following steps:

[0019] S1. Preparation: Prepare the raw ore to make it suitable for the particle size range of the mineral processing facility.

[0020] S2. Installation and Inspection: Correctly install the mineral processing mechanism, ensure the equipment is level and stable, and set reasonable feed concentration, feed rate and flushing water volume, etc.

[0021] S3. Mineral processing: The slurry flows into the top of the spiral channel and is separated by gravity, centrifugal force and water flow.

[0022] S4. Anti-accumulation operation: The anti-accumulation mechanism is driven by the drive mechanism to prevent the accumulation of heavy mineral particles on the inner edge of the tank.

[0023] S5. Accelerated Separation Operation: Through the cooperation of the anti-accumulation mechanism and the separation mechanism, the heavy mineral particles and light mineral particles in the middlings are separated more quickly.

[0024] S6. Product collection: Heavy minerals are deposited near the inner edge of the trough and are eventually collected at the discharge point of the spiral trough.

[0025] Compared with existing technologies, the advantages of this invention are:

[0026] 1. The anti-accumulation mechanism is driven by the drive mechanism. The unblocking plate and unblocking parts are adjusted as needed to carry out the operation. While reducing the interference with the flow of slurry, the flexibility of handling the blockage of heavy mineral particles is improved. When the unblocking plate moves, it pushes the heavy mineral particles that it encounters during the process. After the position of the unblocking plate and unblocking parts changes, multiple diamond-shaped parts push and clear the blockage of a large area.

[0027] 2. The separation mechanism slows down the flow rate of the middlings belt, effectively preventing large flow rates and high velocities in the middlings belt, while accelerating the separation of light and heavy ore particles in the middlings belt and improving the sorting effect; the extension component acts as a buffer for the middlings belt, the separator separates the light ore particles in the middlings belt, and the heavy ore particles are intercepted and separated by the wave-shaped trough, improving the guidance of the inclined top wall of the discharge plate to flow towards the inner edge of the trough.

[0028] 3. Through the cooperation of the anti-accumulation mechanism and the separation mechanism, the heavy mineral particles in the wavy groove are released in a regular manner, allowing the heavy mineral particles to return to the heavy mineral zone in a timely manner, while preventing the accumulation of mineral particles in the dead corner between the bottom wall of the extension and the spiral groove; when the anti-accumulation mechanism moves to the side of the separation mechanism, wedge one pushes wedge two to drive the discharge plate to rotate; the push rod pushes the adjusting rod, and the silicone scraper scrapes the mineral particles in the gap between the bottom wall of the extension and the spiral groove.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Reference Figure 1 A beneficiation device for ilmenite includes a beneficiation mechanism 1, which includes a support frame 11. A mixing chamber 12 is fixedly connected to the top of the support frame 11. A spiral groove 14 is installed in the middle of the support frame 11. The upper and lower ends of the spiral groove 14 are the feeding position and the discharging position, respectively. The inner edge and outer edge of the spiral groove 14 are located near the middle of the support frame 11 and away from the middle of the support frame 11, respectively. A discharge port 13 is fixedly connected to the mixing chamber 12 and is located above the feeding position. A drive mechanism 2 is provided on the support frame 11. An anti-accumulation mechanism 3 is jointly provided on the spiral groove 14 and the drive mechanism 2. The drive mechanism 2 is used to drive the anti-accumulation mechanism 3 to rise and fall along the spiral path on the spiral groove 14. Multiple separation mechanisms 4 are provided on the spiral groove 14.

[0041] The slurry is discharged from the mixing chamber 12 through the discharge port 13 and falls onto the upper feed position of the spiral trough 14. At the same time, supplementary water is added to adjust the concentration of the slurry and enhance mineral stratification through the shear force of the water flow. The slurry flows from top to bottom in the spiral trough 14. Under the action of gravity, centrifugal force and water flow force, heavy mineral particles flow towards the inner edge of the trough. The mixture of heavy mineral particles and light mineral particles forms a middlings zone in the middle of the spiral trough 14, while light mineral particles flow towards the outer edge of the trough. Finally, the slurry is discharged at the discharge position of the spiral trough 14 after being sorted by the cutter (an existing mature device, which will not be described in detail here).

[0042] As the slurry flows along the spiral channel 14, the drive mechanism 2 drives the anti-accumulation mechanism 3 to clear the blockage of heavy mineral particles on the inner edge of the spiral channel 14. The separation mechanism 4 slows down the flow velocity of the middlings while accelerating the separation of heavy mineral particles and light mineral particles in the middlings, thus improving the separation effect.

[0043] Reference Figures 1 to 2 The drive mechanism 2 includes a support column 21. The support column 21 is fixedly connected to the middle of the support frame 11. The support column 21 is connected to an upper and lower sliding ring 22 by an electric slider. The outer ring wall of the upper and lower sliding ring 22 is rotatably connected to a circumferential sliding ring 23.

[0044] Reference Figures 1 to 3 The anti-accumulation mechanism 3 includes a spiral sliding member 31. A blockage-clearing component 33 for preventing the accumulation of heavy mineral particles on the inner edge of the groove is provided on the spiral sliding member 31 via a support plate 32. The outer ring wall of the circumferential sliding ring 23 is rotatably connected to the spiral sliding member 31 via a shaft. The spiral sliding member 31 is slidably connected to the inner edge of the spiral groove 14. The side of the spiral sliding member 31 away from the circumferential sliding ring 23 is slidably connected to the support plate 32 via an electric slider.

[0045] Reference Figures 2 to 4 The unblocking component 33 includes a connecting plate 331. The bottom wall of the support plate 32 is rotatably connected to the connecting plate 331 via a torsion spring rod. One end of the connecting plate 331 is fixedly connected to the unblocking plate 332, and the other end of the connecting plate 331 is hinged to the unblocking component 333. The unblocking component 333 consists of a hinge seat connected to the connecting plate 331 and a plurality of rhomboid components evenly fixed at the bottom of the hinge seat. The bottom wall of the support plate 32 is fixedly connected to a push rod 34 and a wedge block 35.

[0046] As the slurry flows along the spiral groove 14, the upper and lower sliding rings 22 are driven by the electric slider to slide downward on the support column 21. The upper and lower sliding rings 22 drive the spiral sliding component 31 to slide along the inner edge of the spiral groove 14. The shaft connecting the spiral sliding component 31 and the circumferential sliding ring 23 rotates adaptively. The circumferential sliding ring 23 rotates adaptively on the side wall of the upper and lower sliding rings 22. The spiral sliding component 31 drives the support plate 32 and the unblocking component 33 to move. The unblocking plate 332 is in front of the unblocking component 333 in the direction of travel. When the unblocking plate 332 moves, its bottom is in contact with the top wall of the spiral groove 14. The initial position of the unblocking component 333 is not in contact with the top wall of the spiral groove 14.

[0047] When the unblocking plate 332 moves, it pushes out the heavy mineral particles it encounters during its journey. When the unblocking plate 332 encounters a large blockage, the front end of the unblocking plate 332 is lifted after being blocked by the blockage, which drives the connecting plate 331 and the torsion spring rod to rotate. The position of the unblocking component 333 changes to fit against the wall of the spiral groove 14. At this time, the large blockage is pushed out and cleared by multiple diamond-shaped components.

[0048] The unblocking plate 332 has little impact on the flow of slurry. The unblocking component 333 can be adjusted as needed to improve the flexibility of handling blockages caused by heavy mineral particles while minimizing interference.

[0049] It should be noted that when the anti-accumulation mechanism 3 moves from top to bottom to the material cutter near the discharge position, before the drive mechanism 2 drives the anti-accumulation mechanism 3 to reset from bottom to top, the electric slider drives the support plate 32 to slide upward, and the support plate 32 drives the unblocking component 33 to move upward as a whole. The unblocking plate 332 and the unblocking component 333 do not fit against the top wall of the spiral groove 14, so as to avoid affecting the flow of slurry during the reset process.

[0050] Reference Figure 1 , Figure 5 Figure 1 The separation mechanism 4 includes an extension 41 detachably mounted on the spiral groove 14. A separator 42 for separating light mineral particles in the middlings belt is fixedly connected to the extension 41. The extension 41 is provided with a separation component 43 for separating heavy mineral particles in the middlings belt and a scraping component 44 for scraping off mineral particles accumulated between the extension 41 and the spiral groove 14. The extension 41 slows down the flow velocity of the middlings belt by the angle formed between it and the spiral groove 14. The vertical cross section of the separator 42 is triangular. Light mineral particles in the middlings belt flow to the outer edge of the spiral groove 14 through the inclined top wall of the separator 42.

[0051] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 The separation component 43 includes a separation plate 431. The extension 41 is fixedly connected to the side wall of the separation plate 431. The separation plate 431 has multiple wave-shaped grooves that cut off the ore belt through it. The extension 41 is hinged to a discharge plate 432 located below the separation plate 431 by a torsion spring rod. The projections of the separation plate 431 and the discharge plate 432 in the vertical direction overlap. The bottom wall of the separation plate 431 and the top wall of the discharge plate 432 are both inclined towards the inner edge of the groove. The side of the discharge plate 432 near the inner edge of the groove is fixedly connected to a wedge 433 corresponding to the wedge 35.

[0052] Reference Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8The scraping assembly 44 includes a connecting rod 441. The connecting rod 441 is slidably connected to the inside of the extension 41 via a spring (not shown in the figure). The side of the connecting rod 441 near the inner edge of the groove is hinged to a rotating adjustment rod 442 corresponding to the push rod 34 via a torsion spring rod 3. A wedge block 443 is fixedly connected to the side of the connecting rod 441 near the separation plate 431. The side of the wedge block 443 away from the connecting rod 441 is formed by two inclined surfaces in an arrow shape. The bottom wall of the extension 41 is slidably connected to corresponding wedge blocks 5 444 and 6 445 via a spring (not shown in the figure). A groove for the wedge block 6 445 to overlap is opened in the middle of the wedge block 5 444. A silicone scraper block 446 is fixedly connected to the bottom wall of both the wedge block 5 444 and the wedge block 6 445. The side of the wedge block 5 444 and the wedge block 6 445 near the wedge block 3 443 is adapted to the inclined surface of the wedge block 3 443.

[0053] As the slurry flows along the spiral groove 14, the extension 41 acts as a buffer to slow down the flow rate of the middlings, preventing the large flow rate and high velocity of the middlings from causing heavy mineral particles to be difficult to separate effectively, thus resulting in poor separation effect.

[0054] The slurry flows continuously. The slurry in the middlings flows to the separation plate 431 and the separator 42. The light mineral particles in the upper layer of the middlings overflow the highest point of the separator 42 and flow along the inclined top wall of the separator 42 to the outer edge of the spiral groove 14. The mineral particles in the middle layer of the middlings flow with the guidance of the extension 41 and the separation plate 431. After separating from the extension 41 and the separation plate 431, they continue to flow into the middlings of the spiral groove 14 below.

[0055] Some heavy mineral particles in the lower layer of the middle ore zone are intercepted and separated by the wavy trough. As the heavy mineral particles remaining in the wavy trough of the separation plate 431 gradually become heavier, the discharge plate 432 rotates relative to the extension 41 under force, and the heavy mineral particles flow along the inclined top wall of the discharge plate 432 to the inner edge of the trough.

[0056] Furthermore, when the anti-accumulation mechanism 3 moves to the side of the separation mechanism 4, the movement of wedge 1 35 pushes wedge 2 433 downward, causing the discharge plate 432 to rotate relative to the extension 41. Heavy mineral particles flow along the inclined top wall of the discharge plate 432 towards the inner edge of the trough, achieving the effect of releasing heavy mineral particles from the wavy trough. The movement of push rod 34 pushes and rotates the adjusting rod 442, causing the connecting rod 441 to slide inside the extension 41. Wedge 3 443 gradually approaches and pushes wedge 5 444 and wedge 6 445, causing wedge 5 444 and wedge 6 445 to move closer to each other. As wedges 445 change from a state of close proximity to a state of distance, silicone scraper blocks 446 on the bottom wall of extension 41 also change from a state of close proximity to a state of distance. The silicone scraper blocks 446 scrape the mineral particles in the gap between the bottom wall of extension 41 and spiral groove 14 to prevent mineral particles from accumulating in the dead corner of the gap. Until the rotating adjustment rod 442 moves to the point of being blocked by extension 41, the push rod 34 continues to push to make the rotating adjustment rod 442 rotate around the end of connecting rod 441 to adapt and avoid the continuous movement of push rod 34.

[0057] It should be noted that the spiral groove 14 has no fewer than five turns, and the separation mechanism 4 is located in the middle of the spiral groove 14 to reduce the impact on the slurry near the discharge point.

[0058] Furthermore, the present invention also provides a method for beneficiating ilmenite, which is carried out using the aforementioned ilmenite beneficiation equipment, and specifically includes the following steps:

[0059] S1. Preparation: Prepare the raw ore to make it suitable for the particle size range of the mineral processing unit 1.

[0063] S5. Accelerated Separation Operation: Through the cooperation of the anti-accumulation mechanism 3 and the separation mechanism 4, the heavy mineral particles and light mineral particles in the medium ore belt are separated more quickly.

[0064] S6. Product collection: Heavy minerals are deposited near the inner edge of the tank and are eventually collected at the discharge point of the spiral tank 14.
