Description

Technical Field

[0001] The present invention relates to the technical field of mineral separation, and in particular to ilmenite beneficiation equipment and method. Background Art

[0002] Ilmenite is an oxide mineral containing iron and titanium, and is one of the important ores for refining titanium and iron. The spiral chute is a device that uses gravity and centrifugal force to separate minerals. Its working principle is based on the movement differences of mineral particles in the spiral chute. Its simplicity and high efficiency make it widely used in mining and mineral processing.

[0003] During the use of the current spiral chute, the equipment is first installed and fixed vertically, and the slurry is transported to the feed port of the spiral chute. At the same time, supplementary water is added to adjust the slurry concentration. The spiral chute separates the mineral particles through the combined action of gravity, centrifugal force, and water flow. During the separation process, the slurry on the spiral chute is divided into a heavy ore zone, a medium ore zone, and a light ore zone from the inner edge to the outer edge. The heavy ore zone contains heavy ore particles, the light ore zone contains light ore particles, and the medium ore zone contains a mixture of heavy ore particles and light ore particles. Finally, different mineral particles are separated and discharged through the cutter and the ore receiving hopper. However, during the separation process, there is a problem of large flow and fast flow rate in the medium ore zone, which leads to poor separation effect of mineral particles in the medium ore zone. The existing solution is The middle ore zone is re-sorted, which increases the working steps. Secondly, after the heavy mineral particles are separated, they spiral downward through the inner edge of the trough. Due to the small rotation radius of the inner edge of the trough and the large friction between the heavy mineral particles and the trough surface, the heavy mineral particles accumulate. The accumulated heavy mineral particles will block the subsequent flow path of the heavy mineral zone, and part of the heavy mineral zone will flow into the middle ore zone, causing the heavy mineral particles and the middle ore zone to mix, affecting the sorting results. The existing solutions are to add grooves or wedge strips to the spiral chute, optimize the distance-to-diameter ratio, or clean the spiral chute with a manual hand-held scraper. The former has great limitations in designing and changing the main body of the equipment, and requires precise matching of mineral characteristics. The latter is not efficient and cannot deal with the accumulation problem in time.

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

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figure 1 A ilmenite beneficiation equipment includes a beneficiation mechanism 1, which includes a support frame 11. The top of the support frame 11 is fixedly connected to a stirring bin 12. 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 respectively the loading position and the discharging position. The spiral groove 14 is close to the middle of the support frame 11 and away from the middle of the support frame 11. The inner edge and the outer edge of the groove are respectively located. The stirring bin 12 is fixedly connected to a discharge port 13 arranged above the loading position; a driving mechanism 2 is provided on the support frame 11, and an anti-accumulation mechanism 3 is jointly provided on the spiral groove 14 and the driving mechanism 2. The driving mechanism 2 is used to drive the anti-accumulation mechanism 3 to rise and fall in a spiral path on the spiral groove 14. A plurality of separation mechanisms 4 are provided on the spiral groove 14.

[0041] The slurry is discharged from the mixing bin 12 through the discharge port 13 and falls on the upper material position of the spiral trough 14. At the same time, additional water is added to adjust the concentration of the slurry and enhance the mineral stratification through the shear force of the water flow. The slurry flows from top to bottom in the spiral trough 14. Through the action of gravity, centrifugal force and water flow, the heavy mineral particles flow to the inner edge of the trough. The mixture of heavy mineral particles and light mineral particles forms a middle ore zone in the middle of the spiral trough 14, and the light mineral particles flow to the outer edge of the trough. Finally, the material is discharged after sorting by the cutter (which is an existing mature equipment and will not be described in detail here) at the discharge position of the spiral trough 14.

[0042] When the slurry flows along the spiral groove 14, the driving mechanism 2 drives the anti-accumulation mechanism 3 to clear the heavy mineral particles from the inner edge of the spiral groove 14. The separation mechanism 4 slows down the flow rate of the middle ore belt and accelerates the separation of heavy mineral particles and light mineral particles in the middle ore belt, thereby improving the sorting effect.

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

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

[0045] Reference Figures 2 to 4 The blockage clearing assembly 33 includes a connecting plate 331. The bottom wall of the support plate 32 is rotatably connected to the connecting plate 331 through a torsion spring rod. One end of the connecting plate 331 is fixedly connected to a blockage clearing plate 332. The other end of the connecting plate 331 is hinged to a blockage clearing member 333. The blockage clearing member 333 consists of a hinged seat connected to the connecting plate 331 and a plurality of diamond-shaped members evenly fixed at the bottom of the hinged seat. The bottom wall of the support plate 32 is fixedly connected to a push rod 34 and a wedge block 35.

[0046] When 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, and the upper and lower sliding rings 22 drive the spiral slider 31 to slide along the inner edge of the spiral groove 14. The shaft connected to the spiral slider 31 and the circumferential sliding ring 23 rotates adaptively, and the circumferential sliding ring 23 rotates adaptively on the side walls of the upper and lower sliding rings 22. The spiral slider 31 drives the support plate 32 and the clearing assembly 33 to move. The clearing plate 332 is in front of the traveling direction of the clearing member 333. When the clearing plate 332 moves, the bottom is in contact with the top wall of the spiral groove 14, and the initial position of the clearing member 333 is not in contact with the top wall of the spiral groove 14.

[0047] When the clearing plate 332 moves, it pushes the accumulation of heavy mineral particles encountered during the movement. When the clearing plate 332 encounters a large-scale blockage, the front end of the clearing plate 332 is blocked by the blockage and lifts up, driving the connecting plate 331 and the torsion spring rod to rotate. The position of the clearing member 333 changes to fit the wall of the spiral groove 14. At this time, the large-scale blockage is pushed and cleared through multiple diamond-shaped members.

[0048] The clearing plate 332 has little influence on the slurry flow. The clearing piece 333 can be adjusted to operate according to the situation, thereby improving the flexibility of handling the blockage of heavy mineral particles while reducing interference.

[0049] It should be noted that when the anti-accumulation mechanism 3 moves from top to bottom to the cutter near the discharge position, before the driving 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 clearing assembly 33 to move upward as a whole, and the clearing plate 332 and the clearing member 333 are not in contact with the top wall of the spiral groove 14 to avoid affecting the flow of the slurry during the reset process.

[0050] Reference Figure 1 、 Figure 5 Figure 1 The separation mechanism 4 includes an extension piece 41 detachably mounted on the spiral groove 14, a separator 42 for separating light mineral particles in the medium ore belt is fixedly connected to the extension piece 41, a separation component 43 for separating heavy mineral particles in the medium ore belt and a scraping component 44 for scraping mineral particles accumulated between the extension piece 41 and the spiral groove 14 are provided on the extension piece 41; the extension piece 41 slows down the flow rate of the medium ore belt by forming an inclination angle with the spiral groove 14, the vertical cross-section of the separator 42 is triangular, and the light mineral particles in the medium ore 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, and the separation plate 431 is fixedly connected to the side wall of the extension member 41. A plurality of wavy grooves for intercepting the middle ore belt are opened from top to bottom on the separation plate 431. A discharge plate 432 is hingedly connected to the extension member 41 through a second torsion spring rod and is arranged below the separation plate 431; the separation plate 431 and the discharge plate 432 overlap in the vertical direction. The bottom wall of the separation plate 431 and the top wall of the discharge plate 432 are inclined toward the inner edge of the groove, and the discharge plate 432 is fixedly connected to a wedge block 2 433 corresponding to the wedge block 1 35 on the side close to the inner edge of the groove.

[0052] Reference Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8The scraping assembly 44 includes a connecting rod 441, the interior of the extension part 41 is slidably connected to the connecting rod 441 by a spring 1 (not shown in the figure), and the side of the connecting rod 441 near the inner edge of the groove is hinged with a rotating adjustment rod 442 corresponding to the push rod 34 through a torsion spring rod 3. The side of the connecting rod 441 near the separation plate 431 is fixedly connected to a wedge block 3 443, and the side of the wedge block 3 443 away from the connecting rod 441 is formed in an arrow shape by two inclined surfaces.

[0053] When the slurry flows along the spiral groove 14, the extension piece 41 acts as a buffer to the medium ore belt, slowing down the flow rate of the medium ore belt and preventing the medium ore belt from having a large flow rate and a fast flow rate, which makes it difficult to effectively separate the heavy ore particles and thus leads to poor sorting effect.

[0054] The slurry flows continuously, and the slurry in the middle ore band flows to the separation plate 431 and the separator 42. The light ore particles in the upper layer of the middle ore band 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 middle ore band flow under the guidance of the extension piece 41 and the separation plate 431, and continue to flow to the middle ore band of the spiral groove 14 below after leaving the extension piece 41 and the separation plate 431.

[0055] Some heavy mineral particles in the lower layer of the middle ore belt are intercepted and separated by the wavy groove. After the heavy mineral particles remaining in the wavy groove of the separation plate 431 gradually become heavier, the discharge plate 432 is forced to rotate relative to the extension part 41, and the heavy mineral particles flow along the inclined top wall of the discharge plate 432 to the inner edge of the groove.

[0056] In addition, when the anti-accumulation mechanism 3 moves to the side of the separation mechanism 4, the movement of the wedge block 1 35 pushes the wedge block 2 433 downward, driving the discharge plate 432 to rotate relative to the extension member 41, and the heavy ore particles flow along the inclined top wall of the discharge plate 432 to the inner edge of the groove, thereby releasing the heavy ore particles in the wavy groove position; the movement of the push rod 34 pushes the rotating adjustment rod 442, driving the connecting rod 441 to slide inside the extension member 41, and the wedge block 3 443 gradually approaches and pushes the wedge block 5 444 and the wedge block 6 445, and the wedge block 5 444 and The wedge block 445 changes from a state of being close to each other to a state of being far away from each other, and the silicone scraper 446 changes from a state of being close to each other to a state of being far away from each other on the bottom wall of the extension piece 41. The silicone scraper 446 scrapes the mineral particles in the gap between the bottom wall of the extension piece 41 and the spiral groove 14 to prevent the accumulation of mineral particles in the dead corner of the gap; until the rotating adjustment rod 442 moves to be blocked by the extension piece 41, the push rod 34 continues to push to make the rotating adjustment rod 442 rotate around the end of the connecting rod 441 to adapt, and avoid the continuous movement of the push rod 34.

[0057] It should be noted that the number of turns of the spiral groove 14 is not less than five, and the separation mechanism 4 is arranged on the middle turn of the spiral groove 14 to reduce the impact on the slurry close to the discharge position.

[0058] In addition, the present invention also provides an ilmenite beneficiation method, which is completed by using the above-mentioned ilmenite beneficiation equipment, and specifically includes the following steps:

[0059] S1. Preparation: Prepare the raw ore to a particle size range suitable for processing by the ore dressing unit 1.

[0060] S2. Installation and inspection: Correctly install the ore dressing mechanism 1, ensure the equipment is horizontal and stable, and set reasonable feed concentration, feed speed and flushing volume, etc.

[0061] S3, mineral separation: according to the actual situation, the ore pulp flows into the top of the spiral trough 14 at a certain flow rate, and is separated by gravity, centrifugal force and water flow.

[0062] S4, anti-accumulation operation: the anti-accumulation mechanism 3 is driven by the driving mechanism 2 to perform anti-accumulation operation on the heavy mineral particles on the inner edge of the trough.

[0063] S5. Accelerated separation operation: The anti-accumulation mechanism 3 and the separation mechanism 4 cooperate to accelerate the separation of heavy ore particles and light ore particles in the medium ore zone.

[0064] S6. Collecting products: The heavy minerals are deposited near the inner edge of the trough and are finally collected at the discharge position of the spiral trough 14.
