Description

Technical Field

[0001] This invention relates to the field of tailings comprehensive utilization technology, specifically to a convenient and low-consumption tailings treatment system. Background Technology

[0002] In the mining industry, tailings (or tailings ore) are solid wastes remaining after valuable components have been extracted from ore through crushing, grinding, and beneficiation (such as flotation and magnetic separation). These tailings are usually in the form of slurry (i.e., tailings slurry) and need to be properly treated. Tailings treatment systems aim to achieve efficient, low-cost, and environmentally friendly treatment of tailings.

[0003] Compared to existing tailings treatment systems, the following drawbacks exist: traditional tailings treatment and underground backfilling stations in mineral processing plants are often independent or semi-independent systems. Tailings are first transported to the concentrator's thickening well for thickening and sedimentation, and then the backfilling station extracts sand from the concentrator's thickening well. This requires multiple pumping, thickening, and mixing processes, resulting in high energy consumption, large investment, high operating costs, and complex management. Furthermore, overflow water cannot be recycled locally, posing environmental risks. Summary of the Invention

The tailings are first transported to the large concentration well of the mineral processing plant for concentration and sedimentation, and then the backfilling station takes sand from the large concentration well of the mineral processing plant. This requires multiple pumping, concentration and stirring processes, which results in high energy consumption, large investment, high operating costs and complex management. In addition, the overflow water cannot be recycled nearby, which poses environmental risks.

[0005] The objective of this invention can be achieved through the following technical solutions: A convenient and low-consumption tailings treatment system includes: a mineral processing plant, which is connected to a tailings thickening device body via a gravity-flow pipe; the lower end of the tailings thickening device body is connected to a first valve and a second valve via tailings pipes; a stirring drum is connected below the first valve; the tailings thickening device body is connected to an overflow pool via an overflow pipe; and a return water pipe connected to the mineral processing plant is provided on the left side of the overflow pool.

[0006] As a further aspect of the present invention: a top plate is sealed and connected above the main body of the tailings thickening device, a baffle plate fixedly connected to the feed pipe is provided on the inner side of the lower end of the top plate, and a connecting rod located inside the main body of the tailings thickening device is provided below the baffle plate.

[0007] As a further aspect of the present invention: the baffle plate is arranged in a ring and is attached to the inner wall of the tailings thickening device body; a clearance groove is provided on the inner side of the left end of the top plate to accommodate the feed pipe; the left end of the baffle plate is open; and a mixing box is installed above the baffle plate.

[0008] As a further aspect of the present invention: a servo motor is installed at the upper end of the top plate, and a drive gear disk is connected to the lower end of the servo motor. A first driven gear disk and a second driven gear disk are respectively arranged on the left and right sides of the drive gear disk. The diameter of the driving gear disk is half the diameter of the first driven gear disk, and the diameter of the first driven gear disk is half the diameter of the second driven gear disk. Both the first driven gear disk and the second driven gear disk are meshed with the driving gear disk.

[0009] As a further embodiment of the present invention: a support truss is provided at the lower end of the linkage rod, a diversion plate with a triangular longitudinal section is fixedly installed at the upper end of the support truss, and an inclined rake frame is installed at equal intervals at the lower end of the support truss. The lower outer surface of the rake frame is fitted and connected to the inner wall of the tailings thickening device body.

[0010] As a further aspect of the present invention: the lower end of the second driven gear disk is provided with a feeding plate located inside the closed frame, and the right end of the closed frame is provided with a feeding pipe connected to the feeding port.

[0011] As a further aspect of the present invention: the outer side of the conveying plate is provided with filling cavities at equal intervals, the outer surface of the conveying plate is fitted and connected to the inner wall of the closed frame, the upper right side of the closed frame is provided with a feeding cavity, and the lower left side of the closed frame is provided with a discharging cavity.

[0012] As a further aspect of the present invention: the feeding port passes through the closed frame and forms a communication structure with the feeding chamber via a feeding pipe, and the lower interior side of the feeding chamber is inclined; A connecting pipe connected to a mixing box is provided below the discharge chamber, and a fusion box connected to the mixing box is provided on the left side of the connecting pipe.

[0015] The beneficial effects of this invention are: 1. The tailings slurry generated after the mineral processing plant is fed into the tailings thickening device by gravity through chute or pipeline. The valve is opened by the DCS automatic control system. The high-concentration tailings slurry can either flow by gravity to the mixing tank, be mixed evenly with the cementing material, and then flow by gravity through the filling pipeline to the mine for filling the goaf. Alternatively, it can be pressurized by the slurry pump and transported to the tailings dam for storage. The overflow water flows by gravity to the overflow pool and is pumped back to the mineral processing plant for recycling. 2. By utilizing the principle of elevation difference, tailings slurry can flow by gravity to the underground for backfilling throughout the entire process, or it can be pumped and pressurized to the tailings dam for storage. Compared with the processes and systems of other concentrators and backfilling stations, this reduces facilities such as intermediate thickening wells and conveying pump stations, reduces energy consumption for tailings thickening and backfilling, saves investment in intermediate thickening facilities and thickening and conveying costs in concentrators, and returns all overflow water from the tailings thickening unit to the concentrator for production water use. This not only reduces production costs but also avoids environmental incidents caused by tailings water discharge and achieves efficient collaboration between the concentrator and backfilling station.

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-8 As shown, the present invention is a convenient and low-consumption tailings treatment system.

[0021] Example 1 Please see Figure 1 and Figure 2 In this invention, a technical solution is provided: a mineral processing plant 1 is connected to a tailings thickening device body 3 via a gravity flow pipe 2. The lower end of the tailings thickening device body 3 is connected to a first valve 5 and a second valve 6 via a tailings pipe 4. A stirring drum 12 is connected below the first valve 5. The tailings thickening device body 3 is connected to an overflow pool 15 via an overflow pipe 14. A return water pipe 18 connected to the mineral processing plant 1 is provided on the left side of the overflow pool 15.

[0022] Furthermore, a screw feeder 11 connected to the cementitious material silo 9 is provided on the upper right side of the mixing drum 12. A third valve 10 is provided at the connection between the cementitious material silo 9 and the screw feeder 11. A dust collector 8 is installed above the cementitious material silo 9. A filling pipe 13 is provided at the lower end of the mixing drum 12.

[0023] Furthermore, the first valve 5, the second valve 6, the slurry pump 7, the third valve 10, the fourth valve 16, and the water pump 17 are all electrically connected to the DCS control system.

[0024] Specifically, the tailings slurry is first discharged into the tailings thickening unit 3 via gravity flow through a gravity-flow pipe 2 at the lower right end of the concentrator 1. After sedimentation treatment in the tailings thickening unit 3, it is discharged through the tailings pipe 4. There are two treatment methods at this time: First, the first valve 5 is closed while the second valve 6 and slurry pump 7 are opened, allowing the tailings slurry to directly enter the tailings dam for storage. Second, the second valve 6 and slurry pump 7 are closed while the first valve 5 is opened, allowing the tailings slurry to enter the mixing drum 12. Then, the cementitious material is discharged into the mixing drum 12 through the cementitious material silo 9 via the screw feeder 11. After the tailings slurry and cementitious material are mixed, they are discharged directly from the filling pipe 13. At this time, the overflow water generated after sedimentation treatment in the tailings thickening unit 3 will enter the overflow pool 15 through the overflow pipe 14. Then, the fourth valve 16 and water pump 17 are opened to pump the overflow water back into the concentrator 1 for reuse through the return water pipe 18.

[0025] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 1 and Figure 2 In this invention, a technical solution is provided: there are two methods for treating tailings: Method 1: Downhole filling mode. The DCS control system controls the opening of the same direction filling preparation unit. The concentrated tailings slurry flows by gravity to the filling preparation unit and mixes with the cementing material before flowing by gravity to the downhole filling. Method 2: Tailings dam storage mode. The DCS control system controls the opening of the path to the tailings dam conveying unit and starts the slurry pump 7 to pump the tailings slurry to the tailings dam.

[0026] Specifically, in accordance with Embodiment 1, the tailings slurry generated after beneficiation in the mineral processing plant 1 flows by gravity through the gravity pipe 2 into the tailings thickening device body 3 for concentration. When underground backfilling is required, the second valve 6 is remotely closed and the first valve 5 and the third valve 10 are opened via the DCS automatic control system. The screw feeder 11 and the mixing drum 12 are then activated. The concentrated high-concentration tailings slurry flows by gravity through the tailings pipe 4 to the mixing drum 12. Simultaneously, the cementing material is also fed into the mixing drum 12 from the cementing material silo 9 via the screw feeder 11. The tailings slurry and cementing material are then mixed. After the mixing drum 12 is evenly mixed, it flows by gravity through the filling pipe 13 to the mine for filling the goaf. The dust collector 8 above the cementitious material silo 9 filters and removes the dust generated when the cementitious material is fed. When the tailings slurry needs to be switched to the tailings dam, the second valve 6 is opened remotely through the DCS automatic control system, and the slurry pump 7 is started. The tailings slurry is pressurized by the slurry pump 7 and pumped to the tailings dam for storage. After the system is stable, the first valve 5, the third valve 10 and the screw feeder 11 are closed, and the mixing drum 12 is cleaned with water before being shut off.

[0027] Furthermore, while the above systems are operating, the overflow water from the upper layer of the tailings thickening unit 3 flows by gravity through the overflow pool 15 to the fourth valve 16. The DCS automatic control system remotely controls the opening of the water pump 17 and the return water pipe 18, pressurizing the overflow water and returning it to the concentrator for use as circulating water. When the concentrator stops producing tailings slurry, the DCS automatic control system remotely and automatically closes the first valve 5, the second valve 6, the third valve 10, and the water pump 17, and shuts down other related equipment. The DCS automatic control system also controls the tailings thickening unit 3 and its auxiliary facilities.

[0028] Example 3 This embodiment is derived based on Embodiment 1 and Embodiment 2. Please refer to [link / reference]. Figure 3 - Figure 8 In this invention, a technical solution is provided: a top plate 302 is sealed and connected above the body 3 of the tailings thickening device, a baffle plate 303 is fixedly connected to the feed pipe 304 on the inner side of the lower end of the top plate 302, and a connecting rod 30621 located inside the body 3 of the tailings thickening device is provided below the baffle plate 303.

[0029] Furthermore, the baffle plate 303 is arranged in a ring and is attached to the inner wall of the tailings thickening device body 3. The left inner side of the top plate 302 is provided with a clearance groove that can accommodate the feed pipe 304 to pass through. The left end of the baffle plate 303 is open. A mixing box 3031 is installed above the baffle plate 303.

[0030] Furthermore, a servo motor 306 is installed at the upper end of the sealing top plate 302, and a drive gear disk 3061 is connected to the lower end of the servo motor 306. A first driven gear disk 3062 and a second driven gear disk 3063 are respectively provided on the left and right sides of the drive gear disk 3061. The diameter of the driving gear disk 3061 is half the diameter of the first driven gear disk 3062, and the diameter of the first driven gear disk 3062 is half the diameter of the second driven gear disk 3063. Both the first driven gear disk 3062 and the second driven gear disk 3063 are meshed with the driving gear disk 3061.

[0031] Furthermore, a support truss 30622 is provided at the lower end of the linkage rod 30621, a diversion plate 30623 with a triangular longitudinal section is fixedly installed at the upper end of the support truss 30622, and an inclined rake frame 30624 is installed at equal intervals at the lower end of the support truss 30622. The lower outer surface of the rake frame 30624 is fitted and connected to the inner wall of the tailings thickening device body 3.

[0032] Furthermore, the lower end of the second driven gear disk 3063 is provided with a conveying plate 30631 located inside the closed frame 30633, and the right end of the closed frame 30633 is provided with a conveying pipe 3071 connected to the conveying port 307.

[0033] Furthermore, the outer side of the conveying plate 30631 is provided with filling cavities 30632 at equal intervals, the outer surface of the conveying plate 30631 is attached to the inner wall of the closing frame 30633, the upper right side of the closing frame 30633 is provided with a feeding cavity 30634, and the lower left side of the closing frame 30633 is provided with a discharging cavity 30635.

[0034] Furthermore, the feed inlet 307 passes through the feed pipe 3071 through the closed frame 30633 and forms a communication structure with the feed chamber 30634, and the lower side of the inside of the feed chamber 30634 is inclined. Below the discharge chamber 30635, there is a connecting pipe 30636 that is connected to the mixing box 3031. To the left of the connecting pipe 30636, there is a fusion box 30637 that is connected to the mixing box 3031.

[0035] Specifically, in conjunction with Embodiments 1 and 2, after the tailings slurry flows down from the gravity flow pipe 2, it enters the tailings thickening device body 3 through the feed pipe 304. The lower end of the feed pipe 304 adheres to the inner left side wall of the tailings thickening device body 3, preventing the tailings slurry from splashing indiscriminately. When the servo motor 306 mounted on the upper end of the fixed horizontal plate 305 is opened to rotate the drive gear disk 3061, it drives the first driven gear disk 3062 to rotate synchronously and in the same direction, thereby utilizing the rake frame 30624... The mixed tailings slurry that has undergone flocculation and sedimentation is stirred to achieve the effect of solid-liquid separation. An overflow trough 3011 is fixedly installed on the outside of the overflow outlets 301 around the perimeter and is fixedly installed on the body of the tailings thickening device 3. An overflow pipe 14 is installed through the inside of the overflow trough 301, which allows the overflow water to flow from the overflow outlets 301 around the perimeter into the overflow trough 301 for centralized storage, and then be discharged outward along the overflow pipe 14. The concentrated tailings slurry after sedimentation will be discharged from the bottom of the body of the tailings thickening device 3.

[0036] The active gear disk 3061 and the first driven gear disk 3062 are meshed together. When the servo motor 306 is turned on and the active gear disk 3061 is rotated, the first driven gear disk 3062 is driven to rotate synchronously. Since the diameter of the active gear disk 3061 is half the diameter of the first driven gear disk 3062, the connecting rod 30621 can rotate slowly and uniformly. A support truss 30622 is fixedly installed at the lower end of the connecting rod 30621, and a diversion plate 30623 with a triangular longitudinal section is provided at the upper end of the support truss 30622 to prevent tailings slurry from flowing into the feed. When the feed pipe 304 enters the tailings thickening device body 3, it adheres to the upper side of the support truss 30622, causing material accumulation. The rake frame 30624 is evenly distributed at the lower end of the diversion plate 30623, and the lower outer surface of the rake frame 30624 is in close contact with the inner wall of the tailings thickening device body 3, which can stir and scrape the precipitated concentrated tailings. Due to the slow rotation of the rake frame 30624, it exerts a slight squeezing effect on the underflow bed during the scraping process, which helps to further dewater. The rotational resistance of the rake frame 30624 can reflect the thickness and concentration of the tailings thickening device body 3.

[0037] The diameter of the second driven gear disk 3063 is four times that of the driving gear disk 3061. This allows the driving gear disk 3061 to rotate while the driving gear disk 3061 rotates, resulting in a slower rotation of the second driven gear disk 3063. Thus, when the driving gear disk 3061 rotates one revolution, the second driven gear disk 3063 can only rotate one-quarter of a revolution. A conveyor plate 3063 is fixedly mounted on the lower end of the second driven gear disk 3063, located inside the closed frame 30633. 1. The inner side of the conveying plate 30631 is provided with three equally divided packing cavities 30632. When the flocculant enters the feed cavity 30634 through the feed port 307 and the feed pipe 3071, the flocculant will enter the packing cavity 30632 due to the inclined bottom of the feed cavity 30634. Then, through the slow rotation of the packing cavity 30632, the packing cavity 30632 containing flocculant will rotate to the inside of the discharge cavity 30635, and then the flocculant will enter... The flocculant is introduced into the connecting pipe 30636. At this time, the left side of the connecting pipe 30636 is connected to the fusion box 30637, and the fusion box 30637 is connected to the mixing box 3031. The left end of the mixing box 3031 is connected to the feed pipe 304, which enables the flocculant to be initially fused with the tailings slurry. This allows the flocculant to be fed in at multiple points, facilitating rapid concentration. When the tailings slurry enters the mixing box 3031, the flocculant can be evenly dispersed into the mixing box 3031 through the array of fusion boxes 30637, allowing the tailings slurry to be mixed over a large area and to undergo a chemical reaction with the tailings slurry. When the drive gear disk 3061 rotates, it can drive the first driven gear disk 3062 and the second driven gear disk 3063 to rotate synchronously. Due to the difference in rotation speed, when the flocculant enters the tailings thickening device body 3, it forms a differential speed effect with the tailings slurry, which facilitates the quantitative addition of flocculant and improves the mixing and sedimentation effects.

[0038] The feed pipe 304 is fixedly connected to the baffle plate 303. After the top plate 302 is engaged with the tailings thickening device body 3 via the rubber sealing ring 3022, it can be threadedly connected to the tailings thickening device body 3 by bolts 3021 passing through the inner right side of the top plate 302. This not only increases the relative sealing between the top plate 302 and the tailings thickening device body 3, but also facilitates subsequent disassembly and cleaning of the interior of the tailings thickening device body 3. The inner left side of the top plate 302 has a accommodating... The feed pipe 304 passes through the clearance trough, and the left end of the baffle plate 303 is open. When the rake frame 30624 stirs the mixed tailings slurry after flocculation and sedimentation, the overflow water will spread upward. At this time, the overflow water rises continuously along the opening trough at the left end of the baffle plate 303 and enters the overflow water tank 301 through the overflow ports 301 around it. Then it is discharged outward through the overflow pipe 14. The baffle plate 303 can also shield the tailings slurry and flocculant during the stirring process to prevent material splashing.

[0039] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
