Description

Technical Field

[0001] This application relates to the field of slag treatment technology, and more specifically, to a reuse and concentration treatment device for the environmentally friendly and harmless treatment of tailings slag. Background Technology

[0002] Tailings are a product of mineral processing, often resulting from the separation of minerals. Due to their low content of useful components, they cannot be further separated under current technological and economic conditions and thus become tailings. After grinding, the ore becomes a fine-grained slurry, with mineral powder smaller than 0.075mm typically accounting for 50%-70%, and sometimes even finer. The slurry concentration is generally around 15%-40%. If discharged into a tailings dam, it contains not only mineral sands but also a large amount of water, essentially equivalent to a reservoir. The large accumulation of tailings not only causes environmental pollution but also risks tailings dam failures, posing safety hazards. Therefore, how to discharge and store tailings has become a crucial issue. Regarding tailings discharge methods, the main method is dry tailings discharge, a relatively new tailings treatment process that has emerged in recent years. The tailings slurry discharged after mineral processing undergoes multi-stage concentration. Afterwards, the tailings undergo a series of efficient dewatering processes to form slag with low water content, which is easy to settle, solidify, and store on-site. The slag can be sold as building material or transported to a fixed location for dry storage. The tailings dry discharge process can alleviate tailings dam capacity pressure, reduce tailings dam safety hazards, and increase tailings reuse methods. It is a tailings treatment process for achieving green and environmentally friendly mines. In the tailings dry discharge process, a concentration treatment method is usually required. This method involves adding flocculants to the slurry and stirring, followed by static placement to separate solids and liquids, thereby achieving dewatering. However, in the traditional concentration process, some problems are often encountered in the dewatering process.

[0003] Patent document CN116282828B discloses a tailings slag reuse and concentration treatment device, which includes a support frame, a storage base installed at the upper end of the support frame, a concentration tank slidably disposed inside the storage base, a lifting cylinder connecting the storage base and the concentration tank, a stirring component located inside the concentration tank being connected to the storage base via a first fixing frame, water absorption modules evenly disposed around the periphery of the concentration tank, the water absorption modules being squeezed and fitted with the inner sidewall of the storage base, and a controllable opening and closing port provided at the lower end of the concentration tank, with a conveying module corresponding to the position of the opening and closing port installed at the lower end of the storage base.

[0004] The aforementioned application states that after the tailings slurry undergoes flocculation treatment, a lifting cylinder lowers the thickening tank to separate its stirring components, thus initiating dewatering. However, the lifting cylinder carries the entire thickening tank and the tailings slurry and water stored inside, making it heavy and subject to high operating pressure, which can easily cause damage and makes it difficult to process more tailings slag more simply and effectively.

[0026] Example 1, see Figures 1-9This embodiment provides a reuse and concentration treatment device for the environmentally friendly and harmless treatment of tailings slag, including a treatment chamber 1 for treating tailings slurry. A discharge valve is installed at the bottom of the treatment chamber 1. Feed pipes 10, L-shaped, are fixedly connected to both sides of the treatment chamber 1 and are used to connect to external pipelines to transport the tailings slurry into the treatment chamber 1. A beam frame 2 is fixedly connected to the top of the treatment chamber 1, and a guardrail is installed on the beam frame 2. A rotating assembly 3 is installed below the beam frame 2, including a rotating shaft 301. The rotating shaft 301 is rotatably connected to the bottom of the beam frame 2, and a bearing is installed between the rotating shaft 301 and the beam frame 2. A chamber body 302, circular in shape, is fixedly connected to the lower end of the rotating shaft 301, and a circular... The opening has a slidable sealing ring 303 on the inner surface of the compartment 302. The sealing ring 303 is annular in shape, with grooves on both its inner and outer rings. The outer groove matches the circular opening at the top of the compartment 302, acting as a central rotary joint to maintain a seal between the sealing ring 303 and the compartment 302 during relative rotation. A sliding plate 304 is slidably connected to the inner surface of the sealing ring 303, matching the inner groove of the sealing ring 303. The sliding plate 304 is fixedly connected to the outer surface of the rotating shaft 301. A baffle 305 is fixedly connected to the bottom of the compartment 302, with a funnel-shaped lower end. A limiting telescopic rod 306 is fixedly connected to the bottom of the compartment 302, with a cross-sectional shape of...

The stirring assembly 4 includes a rotating rod 401, which is rotatably connected to the bottom of the connecting piece 307. A stirring frame 402 is fixedly connected to the outer surface of the rotating rod 401. The stirring frame 402 is used to stir the tailings slurry to make it mix evenly with the flocculant. A limiting chamber 403 is slidably connected to the outer surface of the stirring frame 402. The limiting chamber 403 is fixedly connected to the bottom of the connecting piece 307. A torsion spring 404 is elastically connected between the inner surface of the limiting chamber 403 and the outer surface of the rotating rod 401.

The limiting chamber 403 and its internal torsion spring 404 and limiting blocks are used to allow the stirring frame 402 to move at a certain angle on the outer surface of the rotating rod 401. When the water suction chamber 601 descends, if the stirring frame 402 is below it, the rounded arc surface at the bottom of the water suction chamber 601 will push the stirring frame 402 to deflect at a certain angle to prevent obstruction. When the rotating rod 401 rotates, it can still drive the stirring frame 402 to rotate for stirring through the limiting blocks. A drive assembly 5 is provided at the top of the rotating shaft 301. The drive assembly 5 includes a support plate 501, which is fixedly connected to the top of the beam frame 2. A motor 502 is fixedly connected to the front of the support plate 501.The output end of the motor 502 is fixedly connected to the upper end of the rotating shaft 301 via a coupling. Water suction components 6 are provided on both the left and right sides of the rotating shaft 301. Each water suction component 6 includes a water suction chamber 601, which is hollow and has a rounded bottom. A filter screen 602 is installed on the water suction chamber 601, specifically in the middle section, to allow external water to enter the chamber. A water pumping pipe connector 603 is fixedly connected to the front of the water suction chamber 601, connecting a pipe to an external suction pump or other water pumping equipment. A limiting rod 604 is fixedly connected to the top of the water suction chamber 601. The limiting rod 604 is a square rod used to limit the lifting and lowering of the water suction chamber 601. The limiting rod 604 passes through and is slidably connected to the bottom of the beam frame 2. A hydraulic assembly 7 is provided between the water suction component 6 and the connecting piece 307. The hydraulic assembly 7 includes a first hydraulic chamber 701, which is fixedly connected to the bottom of the chamber body 302. The first hydraulic chamber 701 communicates with the inner surface of the chamber body 302. A first hydraulic rod 702 is slidably connected to the inner surface of the first hydraulic chamber 701. Under normal conditions, the first hydraulic rod 702... The hydraulic chamber 701 extends to the top. The first hydraulic rod 702 is fixedly connected to the top of the connecting piece 307. A pipe body 703 is fixedly connected through the top of the closed slip ring 303. The pipe body 703 is fixedly connected through the top of the beam frame 2. A second hydraulic chamber 704 is fixedly connected through the top of the beam frame 2. The second hydraulic chamber 704 is connected to the pipe body 703 by a pipeline. The second hydraulic chamber 704 and the pipe body 703 are connected and communicated by a hose. The first hydraulic chamber 701 is connected to the second hydraulic chamber 704 through the chamber body 302, the pipe 703, and the hose. The first hydraulic chamber 701 and the second hydraulic chamber 704 are connected. Hydraulic oil is installed in the hydraulic chambers 704 and the spaces connecting them. The volume of the first hydraulic chamber 701 is equivalent to two second hydraulic chambers 704. There are two sets of second hydraulic chambers 704 and water absorption components 6. A second hydraulic rod 705 is slidably connected to the inner surface of the second hydraulic chamber 704. Under normal conditions, the second hydraulic rod 705 is retracted to the bottom inside the second hydraulic chamber 704. The second hydraulic rod 705 is fixedly connected to the top of the water absorption chamber 601. A scraping component 8 for preventing clogging is installed on the outer surface of the water absorption component 6. A spraying component 9 for uniformly dispensing flocculant is installed on the inner surface of the treatment chamber 1.

[0027] In practical use, the above-mentioned equipment first connects to an external conveying pipeline via the feed pipe 10 to transport the tailings slurry into the treatment chamber 1. Then, flocculant is added to the treatment chamber 1 to facilitate the separation of solids and water in the tailings slurry. After adding the flocculant, the motor 502 is started to drive the rotating shaft 301 to rotate. The rotation of the rotating shaft 301 causes the chamber body 302 and the limiting telescopic rod 306 to rotate the connecting piece 307. The rotation of the connecting piece 307 causes the limiting chamber 403 to rotate on the outer surface of the rotating rod 401, thereby tightening the torsion spring 404 until the first limiting block 405 on the limiting chamber 403 contacts the second limiting block 406 on the rotating rod 401. At this point, the rotation of the connecting piece 307 causes the rotating rod 401 to rotate, thereby rotating the stirring frame 402 to stir the tailings slurry and flocculant. After the solids in the tailings slurry settle, the cylinder is started... 308 pulls the connecting plate 307 upward, which in turn pulls the rotating rod 401 to raise the stirring frame 402, thus separating it from the tailings slurry. At this time, as the connecting plate 307 rises, it also pushes the first hydraulic rod 702 to rise on the inner surface of the first hydraulic chamber 701. The first hydraulic rod 702 pushes the hydraulic oil in the first hydraulic chamber 701 to be injected into the chamber body 302, and then through the pipe body 703 and hose to be injected into the second hydraulic chamber 704. This pushes the second hydraulic rod 705 to extend from the second hydraulic chamber 704. The second hydraulic rod 705 pushes the water suction chamber 601 to descend and insert it into the tailings slurry. At this time, the external suction pump extracts the clean water on the surface of the tailings slurry through the water suction pipe joint 603 and the water suction chamber 601. The solid sediment in the water is filtered by the filter screen plate 602, which facilitates the dewatering of the tailings slurry.

[0028] Example 2, see Figures 1-9The scraping assembly 8 includes a first protective chamber 801, which is spherical in shape. A connecting block 802 is fixedly connected between the first protective chamber 801 and the inner surface of the water absorption chamber 601. A second rotating shaft 803 is rotatably connected through the bottom of the first protective chamber 801. A bearing is provided between the second rotating shaft 803 and the first protective chamber 801. A blade 804 is fixedly connected to the lower end of the second rotating shaft 803. A first rotating shaft 805 is rotatably connected through the right sides of both the first protective chamber 801 and the water absorption chamber 601. A bearing is provided between the first rotating shaft 805 and the first protective chamber 801 and the water absorption chamber 601. A second bevel gear 806 is fixedly connected to the right end of the first rotating shaft 805. A third bevel gear 807 meshes with the bottom of the second bevel gear 806. The third bevel gear 807 is fixedly connected to the upper end of the second rotating shaft 803. The scraping assembly 8 also includes a rotating ring 808, which is connected to the water absorption chamber 601. 1. The outer surface is slidably connected. The rotating ring 808 and the water suction chamber 601 are connected by an annular groove. The rotating ring 808 can rotate on the outer surface of the water suction chamber 601. A face gear 809 is fixedly connected to the top of the rotating ring 808. A first bevel gear 810 meshes with the top of the face gear 809. The first bevel gear 810 is fixedly connected to the left end of the first rotating shaft 805. A second protective chamber 811 is slidably connected to the outer surface of the rotating ring 808. The second protective chamber 811 is connected to the rotating ring 808 by an annular groove. The second protective chamber 811 is used to protect the face gear 809 and the first bevel gear 810 to prevent solid impurities in the tailings slurry in the water from adhering to them and affecting the meshing effect. The second protective chamber 811 is fixedly connected to the outer surface of the water suction chamber 601. A scraper 812 is fixedly connected to the bottom of the rotating ring 808. The scraper 812 is set on the outer surface of the filter screen plate 602 and fits against it.

[0029] In practical use, when the water suction chamber 601 begins to extract clean water from the surface of the tailings slurry, the water rises within the water suction chamber 601 after passing through the filter screen 602. At this time, the water flow impacts the blades 804, causing the second rotating shaft 803 to rotate. The rotation of the second rotating shaft 803 drives the third bevel gear 807 to engage the second bevel gear 806, causing the first rotating shaft 805 to rotate. The first rotating shaft 805 then drives the first bevel gear 810 to rotate, engaging the face gear 809, which in turn drives the rotating ring 808 to rotate on the outer surface of the water suction chamber 601. The rotation of the rotating ring 808 causes the scraper 812 to scrape the outer surface of the filter screen 602, thereby scraping off solid impurities in the tailings slurry adhering to the filter screen 602, ensuring the unobstructed flow of the filter screen 602, and thus guaranteeing the water suction performance.

[0030] Example 3, see Figures 1-9The spraying assembly 9 includes an annular chamber 901, which is annular in shape with an open top. A connecting rod 902 is fixedly connected between the annular chamber 901 and the baffle 305. A pipe rotary joint 903 is fixedly connected to the bottom of the annular chamber 901. The pipe rotary joint 903 is a central rotary joint. A nozzle 904 is fixedly connected to the lower end of the pipe rotary joint 903. Two feeding hoppers 905 are fixedly connected through the top of the beam frame 2. The spraying assembly 9 also includes a toothed ring 906. 06 is fixedly connected to the bottom of the beam frame 2. A limiting cylinder 907 is fixedly connected to the outer surface of the annular chamber 901. A rotating rod 908 is rotatably connected to the inner surface of the limiting cylinder 907. A bearing is provided between the limiting cylinder 907 and the rotating rod 908. A first gear 909 is fixedly connected to the upper end of the rotating rod 908. The first gear 909 meshes with the outer surface of the gear ring 906. A second gear 910 is fixedly connected to the lower end of the rotating rod 908. A third gear 911 meshes with the outer surface of the second gear 910. The third gear 911 is fixedly connected to the outer surface of the nozzle 904.

[0031] In practical use, when flocculant needs to be added to the treatment chamber 1, it is fed into the feeding hopper 905 and allowed to leak into the annular chamber 901. The flocculant is then sprayed into the treatment chamber 1 through the pipe rotary joint 903 and nozzle 904. At this time, as the motor 502 drives the rotating shaft 301, the chamber body 302 rotates, which in turn drives the baffle 305 and connecting rod 902 to rotate the annular chamber 901. The flocculant is then evenly distributed within the annular chamber 901 and sprayed from multiple nozzles below the annular chamber 901. When the nozzle 904 is sprayed out, the rotation of the annular chamber 901 will also drive the limiting cylinder 907 and the rotating roller 908 to make the first gear 909 roll on the outer surface of the gear ring 906. At this time, the first gear 909 will drive the rotating roller 908 to rotate inside the limiting cylinder 907. The rotation of the rotating roller 908 will drive the second gear 910 to move the third gear 911 to make the nozzle 904 rotate, so as to evenly spray the flocculant in the treatment chamber 1, thereby facilitating faster and more uniform mixing between the flocculant and the tailings slurry.
