Description

Technical Field

[0001] The present invention relates to the technical field of tailings recovery devices, and in particular to a tin tailings classification recovery device and process. Background Art

[0002] Tin is widely used in electronics, information, electrical appliances, chemicals, metallurgy, building materials, machinery, food packaging and other industries because of its soft and ductile texture, stable chemical properties, corrosion resistance, fusibility and low friction coefficient.

[0003] Chinese invention patent application publication number CN116889925A discloses a method for recovering tin and iron from tin tailings by pre-enrichment and sorting. This method, which belongs to the field of tailings processing technology, first separates the tin tailings into different particle size grades. After classification, the tailings of different particle sizes are sorted and treated using different methods, resulting in precise separation of cassiterite and hematite. This method achieves the separation of tin and iron, which are difficult to separate in the tin tailings, and not only recovers the tin in the tailings, but also recovers the iron. The method can produce a tin concentrate with a tin grade exceeding 3% and a recovery rate exceeding 65%, and an iron concentrate with an iron grade exceeding 60% and a recovery rate exceeding 70%. The method has the advantages of strong operability, low cost, and excellent tin and iron separation performance.

[0004] Chinese invention patent publication number CN115121361B discloses a tin ore beneficiation shaker and tin ore beneficiation method, comprising the following steps: three-stage classification: flotation tailings are classified into three stages, with the classification criteria being that sand ore larger than 74 microns is designated as a first sand ore, sand ore ≤74 microns and ≥38 microns is designated as a second sand ore, and sand ore smaller than 38 microns is designated as a mud ore; the first and second sand ore are subjected to shaker beneficiation, respectively. The flotation tailings are then classified into three stages based on particle size, with the larger tailings from the first and second stages subjected to shaker beneficiation to further refine the tin ore contained therein, thereby improving tin ore recovery and reducing resource waste.

[0005] Announcement number CN212524517U is a suspended vibration cone beneficiation equipment, including a sorting disc with a vibration mechanism and a rotary drive device, a sorting trough installed below the sorting disc, and an involute washing water pipe installed above the sorting disc. The sorting disc includes an inner cone and an outer cone, the slope of the inner cone is greater than the slope of the outer cone, and the sorting disc is formed by smoothly connecting the inner cone and the outer cone. Beneficial effect: The sorting disc is designed with two cones of different slopes connected. Compared with the design of the sorting disc with a single slope as a whole, it can make the light minerals in the slurry enter the tailings faster and increase the overall flow rate of the slurry, thereby improving the speed and efficiency of sorting as well as the sorting accuracy.

[0006] In the above-mentioned method of tin tailings classification pre-enrichment and classification sorting to recover tin and iron, after the tin ore of different particle sizes is sorted out by the sorting equipment, the tin ore of different particle sizes is screened separately by the suspension vibration equipment and the shaking table. The multiple devices complete different processes respectively, and the overall system occupies a large area. In addition, a transport device is required to transport the tin ore between the multiple devices, which occupies a large amount of resources and causes inconvenience to the long-term tin tailings classification and recovery operation. Therefore, the existing technology has a technical problem of inconvenient tin tailings recovery. Summary of the Invention

[0028] The process includes the following steps:

[0029] Feeding: The water spray mechanism sprays water into the sedimentation tank and the inner side of the inner cone section, so that the water level inside the inner cone section is higher than the top of the inner cone section and then overflows to the upper surface of the outer cone section, and tin tailings are fed into the water spray mechanism from the top of the sedimentation tank;

[0030] Particle size separation: The water flow from the water spray mechanism drives the tin tailings to move upward. After the water flow rises to the liquid surface, it flows toward the outer cone section, making the tin tailings tend to move toward the outer cone section. The coarse-grained ore with larger particle size sinks faster into the sedimentation tank with greater weight, while the fine-grained ore with smaller particle size sinks slower to the upper surface of the inner cone section with less weight.

[0031] Tin ore collection: The turntable rotates on the sliding frame, and the fine-grained ore on the upper surface of the inner cone section rotates with the turntable and abuts against the arc-shaped scraper. The fine-grained ore moves to the upper end of the outer cone section along the extension direction of the arc-shaped scraper. The coarse-grained ore on the upper surface of the bottom wall of the sedimentation trough rotates with the turntable and abuts against the sedimentation scraper. The coarse-grained ore moves to a position close to the side wall of the sedimentation trough along the extension direction of the sedimentation scraper until the discharge port moves below the sedimentation scraper. The coarse-grained ore at the sedimentation scraper falls downward into the discharge port. When the discharge port rotates to a position corresponding to the discharge trough, the coarse particles enter the discharge trough and then fall from the discharge trough onto the shaking table.

[0032] Screening of tin ore: The sliding frame drives the turntable to reciprocate on the frame, turning out the impurities in the fine-grained ore on the outer cone section, and the water on the inner cone section overflows onto the outer cone section. The water flow washes the impurities in the fine-grained ore on the outer cone section to the edge of the outer cone section. The turntable drives the fine-grained ore to rotate during the rotation process, and the water sprayed by the sprinkler pipe washes the fine-grained ore, causing the fine-grained ore to roll along the extension direction of the arc section to the top of the collection box and then fall into the collection box. The sliding frame drives the shaker to move, and the shaker separates impurities in the coarse-grained ore during the reciprocating motion.

[0033] Through such a setting: during the sorting and screening process, there is no need for a conveying device to transport the tin tailings. The operator only needs to operate on one device to complete the sorting, suspension vibration beneficiation and shaking table beneficiation of tin ore, achieving the advantage of convenient screening and recovery of tin tailings.

[0034] Compared with the prior art, the present invention has achieved beneficial technical effects:

[0035] In the process of sorting tin tailings of different particle sizes, the present invention utilizes water flow to flush the tin tailings upward to the liquid surface. After the water flows upward to the top, it spreads to the surroundings and drives the tin tailings to move, thereby sorting the tin tailings by gravity. Then the water discharged from the inner cone section is used again to screen the fine-grained ore on the outer cone section, and the water in the sedimentation tank can also be used to flush the coarse-grained ore in the discharge port and the discharge trough onto the shaking table, thereby realizing the reuse of water and reducing the use of water resources; in the process of driving the sliding frame to vibrate back and forth on the frame, it can drive the turntable and the shaking table to move at the same time, so there is no need to set up equipment separately to provide power for the suspended vibration beneficiation and shaking table beneficiation of tin ore, thereby improving the utilization efficiency of equipment; the water flow sprayed by the water spray mechanism quickly disperses the tin tailings, ensuring the screening accuracy of the tin tailings and preventing the tin tailings from agglomerating and unable to be screened normally; the equipment layout is reasonable and compact, and the footprint is small. During the sorting and screening process, no conveying device is required to transport the tin tailings. The operator only needs to operate on one device to complete the sorting, suspended vibration beneficiation and shaking table beneficiation of tin ore, thereby achieving the advantage of convenient screening and recovery of tin tailings.

A sedimentation tank 22 is provided in the middle of the turntable 21. The turntable 21 is provided with an inner cone section 23 arranged around the upper end of the sedimentation tank 22. The lower end of the inner cone section 23 is inclined toward the direction close to the sedimentation tank 22. The turntable 21 is provided with an outer cone section 24 arranged around the outer edge of the inner cone section 23. The lower end of the outer cone section 24 is inclined toward the direction away from the sedimentation tank 22. The water spraying mechanism is installed at the bottom of the sedimentation tank 22. The sprinkler pipe 31 is located above the turntable 21. The bottom of the sprinkler pipe 31 is provided with a sprinkler hole facing the outer cone section 24. The sprinkler pipe 31 is provided with an arc section 32. The two ends of the arc section 32 are respectively located at the inner edge and the outer edge of the outer cone section 24.

The end of the shaking table 61 in the longitudinal direction, which is close to the shaking table 61, is tilted downward. The end of the shaking table 61 in the width direction, which is away from the water spray pipe 62, is tilted downward. This allows the shaking table 61 to shake the tin ore into the collection box 14 during the reciprocating vibration process, while the lighter impurities in the coarse-grained ore are washed out of the shaking table 61 by the water flow along the width direction of the shaking table 61. The support frame 33 is provided with a feed port 36 located above the sleeve 41. The width of the feed port 36 is smaller than the width of the top of the conical guide block 45. This ensures that the tin tailings introduced into the sedimentation tank 22 through the feed port 36 can be delivered to the middle of the conical guide block 45, facilitating the delivery of material to the water spray mechanism.

The water spray pipe 62 and the sprinkler pipe 31 are connected to an external water source.

[0047] A tin tailings classification recovery process, the process comprising the following steps:

[0048] Feeding: The water spray mechanism sprays water into the sedimentation tank 22 and the inner side of the inner cone section 23, so that the water level inside the inner cone section 23 is higher than the top of the inner cone section 23 and then overflows to the upper surface of the outer cone section 24, and tin tailings are fed into the water spray mechanism from the top of the sedimentation tank 22;

[0049] Particle size separation: The water flow sprayed by the water spray mechanism drives the tin tailings upward. After the water flow rises to the liquid surface, it flows toward the outer cone section 24, causing the tin tailings to have a tendency to move toward the outer cone section 24. The coarse-grained ore with larger particle size sinks faster into the sedimentation tank 22 with greater weight, while the fine-grained ore with smaller particle size sinks slower to the upper surface of the inner cone section 23 with less weight.

[0050] Collecting tin ore: The turntable 21 rotates on the sliding frame 13, and the fine-grained ore on the upper surface of the inner cone section 23 rotates with the turntable 21 and abuts against the arc scraper 35. The fine-grained ore moves to the upper end of the outer cone section 24 along the extension direction of the arc scraper 35. The coarse-grained ore on the upper surface of the bottom wall of the sedimentation trough 22 rotates with the turntable 21 and abuts against the sedimentation scraper 34. The coarse-grained ore moves to a position close to the side wall of the sedimentation trough 22 along the extension direction of the sedimentation scraper 34 until the discharge port 25 moves below the sedimentation scraper 34. The coarse-grained ore at the sedimentation scraper 34 falls downward into the discharge port 25. When the discharge port 25 rotates to a position corresponding to the discharge trough 27, the coarse particles enter the discharge trough 27 and then fall from the discharge trough 27 onto the shaking table 61;

[0051] Screening of tin ore: The sliding frame 13 drives the turntable 21 to reciprocate on the frame 11, turning out impurities in the fine-grained ore on the outer cone section 24, and the water on the inner cone section 23 overflows onto the outer cone section 24. The water flow washes the impurities in the fine-grained ore on the outer cone section 24 to the edge of the outer cone section 24. The turntable 21 drives the fine-grained ore to rotate during the rotation process, and the water sprayed by the sprinkler pipe 31 washes the fine-grained ore, causing the fine-grained ore to roll along the extension direction of the arc section 32 to the top of the collection box 14 and then fall into the collection box 14. The sliding frame 13 drives the shaker 61 to move, and the shaker 61 separates impurities in the coarse-grained ore during the reciprocating motion.

[0052] This embodiment has the following advantages:

[0053] In the sedimentation tank 22 and the inner cone section 23, the tin tailings are washed to the liquid surface by the water flow, and by the action of gravity, the coarse-grained ore with a particle size greater than 0.1 mm is heavier and falls faster in the water, while the fine-grained ore with a particle size less than 0.1 mm is lighter and falls slower in the water. In the process of the tin tailings moving to the outer cone section 24 with the water flow at the liquid surface, the coarse-grained ore with a faster falling speed falls into the sedimentation tank 22, while the fine-grained ore with a slower falling speed falls on the upper surface of the inner cone section 23, thereby sorting out tin tailings of different particle size ranges. The fine-grained ore is scraped onto the outer cone section 24 by the arc scraper 35. The fine-grained ore on the outer cone section 24 is washed by vibration and water flow, thereby realizing suspended vibration beneficiation of tin ore, which is suitable for screening tin ore with smaller particle size and has high screening efficiency; the coarse-grained ore is scraped into the discharge port 25 by the sedimentation scraper 34. When the discharge port 25 and the discharge trough 27 are connected, the water in the sedimentation trough 22 flushes the coarse-grained ore in the discharge port 25 from the discharge trough 27 to the shaking table 61. The shaking table 61 realizes the beneficiation of tin ore by the shaking table 61 through vibration and water flow, which is suitable for screening tin ore with larger particle size and has high screening accuracy.

[0054] In the process of sorting tin tailings of different particle sizes, the present invention utilizes water flow to flush the tin tailings upward to the liquid surface. After the water flows upward to the top, it spreads to the surroundings and drives the tin tailings to move, thereby sorting the tin tailings by gravity. Then, the water discharged from the inner cone section 23 is used again to screen the fine-grained ore on the outer cone section 24, and the water in the sedimentation tank 22 can also be used to flush the coarse-grained ore in the discharge port 25 and the discharge trough 27 onto the shaking table 61, thereby realizing the reuse of water and reducing the use of water resources; in the process of driving the sliding frame 13 to vibrate back and forth on the frame 11, the turntable 21 and the shaking table 61 can be driven to move at the same time, so there is no need to set up equipment separately to provide power for the suspended vibration beneficiation of tin ore and the beneficiation of the shaking table 61, thereby improving the utilization efficiency of the equipment; the water flow sprayed by the water spraying mechanism quickly disperses the tin tailings, ensures the screening accuracy of the tin tailings, and prevents the tin tailings from agglomerating and unable to be screened normally; the equipment layout is reasonable and compact, and the footprint is small. During the sorting and screening process, no conveying device is required to transport the tin tailings. The operator only needs to operate on one device to complete the sorting, suspended vibration beneficiation and beneficiation of the shaking table 61, thereby achieving the advantage of convenient screening and recovery of the tin tailings.

[0055] With this arrangement, the reduction motor 17 drives the inertia wheel 15 to rotate. During rotation, the inertia wheel 15 drives the carriage 13 to vibrate back and forth on the frame 11 via the connecting rod 16, thereby achieving the function of driving the carriage 13 to vibrate back and forth on the frame 11. The inertia of the inertia wheel 15 maintains its original angular velocity, making the frequency of the vibration of the carriage 13 driven by the connecting rod 16 more stable.

[0056] With this arrangement, water is injected into the water inlet hose 42, and the water enters the sleeve 41 through the water inlet hose 42. The drive shaft 43 rotates, and the shaft 43 drives the impeller 44 to rotate and drives the water in the sleeve 41 to flow toward the sedimentation tank 22, thereby realizing the function of spraying water into the sedimentation tank 22 through the water spray mechanism.

[0057] Through such an arrangement: the water in the sleeve 41 is guided by the conical guide block 45 to be sprayed against the inner wall of the sleeve 41, so that a water column with a circular cross-section can be sprayed, and the tin tailings are placed in the center of the circular water column, thereby ensuring that the tin tailings can be washed upward by the water flow before falling to the inner wall of the sedimentation tank 22, thereby ensuring the sorting effect of the tin tailings.

[0058] By such an arrangement, the driving shaft 51 is rotated, and the driving shaft 51 drives the rotating shaft 43 to rotate through the driving pulley 52 , the transmission belt 54 and the driven pulley 53 , thereby realizing the function of driving the rotating shaft 43 to rotate on the sliding frame 13 .

[0059] Through such an arrangement, the motor 55 drives the driving shaft 51 to rotate through the driving gear 56 and the driven gear 57 , thereby achieving the function of driving the driving shaft 51 to rotate.
