Description

Technical Field

[0001] This invention relates to the field of tailings water treatment equipment technology, specifically a thickener for tailings water settling. Background Technology

[0002] In the mineral processing of mines, a large amount of tailings slurry rich in fine mineral particles and suspended impurities is generated. The industry commonly uses thickeners to settle and concentrate the tailings slurry, achieving solid-liquid separation and recycling of production water. However, existing conventional thickeners have rudimentary water distribution structures, allowing tailings slurry to flow directly into the tank, generating violent turbulent impacts that easily break up the already flocculated flocs. This results in slow and incomplete settling of fine tailings particles, significantly reducing overall solid-liquid separation efficiency and causing excessive suspended solids in the supernatant. The water quality is poor. Secondly, traditional thickeners rely solely on a single scraper to scrape sludge from the bottom of the tank. During the scraping process, the scraper easily stirs up the surface fine sludge, forming suspended turbid water. A large number of fine mineral particles float to the surface and mix with the upper clear water, further deteriorating the effluent quality. The floating fine sludge is discharged with the overflow clear water without completing the sedimentation and concentration process, and cannot be recycled to the bottom flow for tailings dry discharge. This has resulted in the long-term waste of metal ore and tailings resources and reduced the utilization rate of mining resources. In response to the above problems, the inventors have proposed a thickener for tailings water sedimentation to solve these issues. Summary of the Invention

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention, by setting up a sludge scraping and anti-splash suction component, uses a sludge scraper at the bottom of the rake frame to scrape and collect the deposited sludge along the contour of the bottom of the thickening tank in all directions, avoiding local sludge accumulation and compaction, and ensuring continuous and stable bottom flow discharge; at the same time, it is equipped with a suction frame, suction port and suction channel, which can absorb the suspended sludge water disturbed by the sludge scraping operation in real time, prevent the diffusion of fine mineral particles to contaminate the supernatant, reduce the loss of tailings particles, and the collected sludge water flows back to the built-in liquid guide frame through the pipeline, and with the mechanical self-driven cylinder pump suction structure, realize the internal circulation and secondary sedimentation of sludge, and simultaneously achieve multiple effects of full-area sludge scraping, anti-splash water purification and tailings recovery; 2.

[0011] 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.

[0012] Example: Figure 1-14As shown, the present invention provides a technical solution: a thickener for tailings water settling, including a thickening tank 1, a bridge frame 2, a mounting base 3, and a rotating cylinder 4. The bridge frame 2 is installed across the top of the thickening tank 1 and provides stable support for the overall device. The mounting base 3 is fixedly installed at the middle of the top of the bridge frame 2. The rotating cylinder 4 is rotatably installed at the middle of the bridge frame 2 via a circular guide rail. The rotating cylinder 4 is provided with a sludge scraping and splash prevention suction component 5 for scraping sludge and a uniform water distribution component 6 for uniform water distribution. The bottom of the bridge frame 2 is provided with a rotation drive component 7 for driving the rotating cylinder 4 to rotate. The top of the mounting base 3 is equipped with a water distribution tank 8, and the liquid inlet end of the water distribution tank 8 is connected to a slurry inlet pipe 9. The sludge scraping and anti-splash suction assembly 5 includes two opposing rake frames 501, which are fixed to the left and right sides of the rotating cylinder 4 respectively. Six suction frames 502 are evenly spaced along the bottom outline of the thickening tank 1 at the bottom of the rake frames 501. Four suction ports 504 arranged in a rectangular array are inclined on both sides of the suction frames 502. Two symmetrically arranged suction channels 505 are opened on the top of the suction frames 502, and the four suction ports 504 are respectively connected to the corresponding suction channels 505. A sludge scraper 503 is fixedly installed at the bottom of the suction frame 502. An internal liquid guide frame 506 is fixedly installed on the inner wall of the rotating cylinder 4. An internal liquid guide seat 507 is rotatably sealed inside the internal liquid guide frame 506. Two symmetrically arranged support rods 509 are fixedly installed at the top of the internal liquid guide seat 507, and the top of the support rods 509 is fixedly connected to the mounting base 3. The uniform water distribution assembly 6 includes two water distribution frames 601 arranged corresponding to the rake frame 501. The bottom end of the water distribution frame 601 is fixedly connected to the rake frame 501 through a bracket. Three equally spaced guide water distribution frames 602 are fixedly installed at the top of the water distribution frame 601. Five sets of staggered diversion columns 603 are fixedly installed inside the guide water distribution frames 602.

[0013] By adopting the above technical solution, the rotating cylinder 4 drives the sludge scraping and splash prevention suction component 5 and the uniform water distribution component 6 to rotate synchronously under the drive of the rotating drive component 7; the tailings slurry enters the water distribution tank 8 through the slurry inlet pipe 9 and is distributed to the uniform water distribution component 6. After being stabilized and evenly distributed by the staggered diversion column 603 in the guide water distribution frame 602, it slowly enters the thickening tank 1 to achieve sedimentation; the sludge scraping and splash prevention suction component 5 rotates with the rake frame 501, scrapes the sludge at the bottom of the tank through the sludge scraper 503, and sucks the splashed sludge into the collection channel 505 for return treatment through the suction port 504, realizing the integrated operation of scraping sludge, preventing splashing, and circulating water distribution at the same time.

[0014] The rotary drive assembly 7 includes an external gear ring 701 and a drive motor 702. The external gear ring 701 is fixedly installed on the outer wall of the rotating cylinder 4. The drive motor 702 is fixedly installed on the bridge frame 2 via a base. A drive gear 703 is fixedly installed on the drive end of the drive motor 702, and the drive gear 703 meshes with the external gear ring 701.

[0015] By adopting the above technical solution, the drive motor 702 drives the drive gear 703 to rotate, and the drive gear 703 meshes with the external gear ring 701 to drive the rotating cylinder 4 to rotate continuously around its own axis, providing rotational power for the rake frame 501, the water distribution frame 601 and the internal transmission mechanism.

[0016] A cylinder 510 is fixedly installed at the top center of the built-in liquid guide seat 507. A piston rod 511 is provided in the middle of the cylinder 510, and a sealing piston 512 and a slide block 513 are fixedly installed at both ends of the piston rod 511. The sealing piston 512 is vertically sealed and slidably installed inside the cylinder 510, and the slide block 513 is slidably installed on the support rod 509.

[0017] By adopting the above technical solution, the piston rod 511 drives the sealed piston 512 to slide up and down in the cylinder 510, forming a pumping action; the slide block 513 slides vertically along the support rod 509 to ensure the smooth movement of the piston rod 511.

[0018] The built-in liquid guide seat 507 has an outlet flow channel 508. The outlet flow channel 508 is connected to the liquid inlet end of the cylinder 510 through a one-way valve. The liquid outlet end of the cylinder 510 is connected to the water distribution tank 8 through a one-way valve and a conduit. The liquid outlet end of the suction frame 502 is connected to the liquid inlet end of the built-in liquid guide frame 506 after the liquid flows back through the conduit.

[0019] By adopting the above technical solution, the cylinder 510 forms a negative pressure when it moves upward, which draws the sludge collected by the suction frame 502 into the built-in liquid guide frame 506 through the guide pipe, and then into the cylinder 510 through the outlet flow channel 508 and the one-way valve; the cylinder 510 forms a positive pressure when it moves downward, which pushes the sludge through the one-way valve and the guide pipe to the water distribution tank 8 to participate in water distribution and sedimentation again, thereby realizing the internal circulation and return treatment of sludge.

[0020] A rotating shaft 515 is rotatably mounted in the middle of the mounting base 3 via a bearing. A guide cylinder 516 is fixedly mounted at the bottom of the rotating shaft 515. A wave-shaped guide groove 517 is opened on the outer side of the guide cylinder 516. Two symmetrically arranged guide plates 514 are fixedly mounted at the top of the slide block 513. A guide bolt 518 is fixedly mounted on the inner side of the top of the guide plate 514, and the guide bolt 518 slides in the wave-shaped guide groove 517.

[0021] By adopting the above technical solution, the rotating shaft 515 drives the guide cylinder 516 to rotate, and the guide bolt 518 rolls and slides along the wave guide groove 517, driving the guide plate 514 and the slide block 513 to move up and down in a straight line along the support rod 509, thereby driving the piston rod 511 and the sealing piston 512 to reciprocate and pump, realizing the self-driven pumping action.

[0022] An auxiliary shaft 519 is rotatably mounted on one side of the mounting base 3 via a bearing. An internal gear ring 520 is fixedly mounted on the inner wall of the rotating cylinder 4. A transmission gear 521 is fixedly sleeved on the outer wall of the auxiliary shaft 519. A driven gear 522 is fixedly mounted on the outer wall of the rotating shaft 515. Both ends of the transmission gear 521 are respectively meshed with the driven gear 522 and the internal gear ring 520.

[0023] By adopting the above technical solution, the rotating cylinder 4 rotates, driving the built-in gear ring 520 to rotate. The built-in gear ring 520 meshes with the transmission gear 521, and the transmission gear 521 meshes with the driven gear 522 to drive the rotating shaft 515 to rotate synchronously, realizing the pure mechanical conversion of rotational power into reciprocating pump suction motion, without the need for an additional power source.

[0024] An external liquid guide seat 605 is fixedly installed on the outer wall of the rotating cylinder 4 near the external toothed ring 701. An external liquid guide frame 604 is rotatably and sealingly connected to the outer wall of the external liquid guide seat 605, and the external liquid guide frame 604 is fixedly connected to the cable tray 2 through a support plate.

[0025] By adopting the above technical solution, the external liquid guide frame 604 is kept relatively fixed with the bridge 2, and the external liquid guide seat 605 rotates synchronously with the rotating cylinder 4, forming a rotational sealing fit between the two, which ensures the rotational sealing effect while realizing the slurry transportation and preventing slurry leakage.

[0026] The external liquid guide seat 605 has six drainage ends connected to water distribution pipes 606, and the other end of the water distribution pipes 606 is fixedly connected to the corresponding water distribution frame 602 through a support plate.

[0027] By adopting the above technical solution, the slurry is distributed to each water distribution pipe 606 through the external liquid guide seat 605, and then transported to the corresponding guide water distribution frame 602 by the water distribution pipe 606, so as to achieve multi-point, uniform and synchronous water distribution.

[0028] The external liquid guide frame 604 has a slurry guide pipe 607 connected to its inlet end, and the other end of the slurry guide pipe 607 is connected to the bottom of the water distribution tank 8.

[0029] By adopting the above technical solution, the tailings slurry in the water distribution tank 8 enters the external liquid guiding frame 604 through the slurry guiding pipe 607, and then flows into the external liquid guiding seat 605 to complete the continuous slurry supply in the rotating state.

[0030] The water distribution frame 602 adopts a trapezoidal frame structure, and the bottom of the water distribution frame 602 is formed into a continuous slightly wavy curved surface.

[0031] By adopting the above technical solution, the bottom of the guide water distribution frame 602 has a continuous slight wavy curved surface, which, together with the internal staggered diversion column 603, effectively reduces the kinetic energy of the slurry flow, avoids impacting and disturbing the flocs, and allows the slurry to diffuse smoothly into the thickening tank 1, thereby improving the sedimentation and separation effect. The guide water distribution frame 602 is arranged at an angle, and the angled outlet end of the guide water distribution frame 602 is immersed below the surface of the thickening tank 1.

[0032] Working principle: In the actual tailings water treatment process, the mine tailings wastewater is first sent to the distribution tank 8 through the slurry inlet pipe 9 to complete pressure stabilization and buffering. The stabilized tailings slurry is then introduced into the external liquid guiding frame 604 fixed to the bridge frame 2 through the slurry guide pipe 607, and enters the external liquid guiding seat 605 that rotates synchronously with the rotating cylinder 4. Then, it is evenly transported to each inclined guide water distribution frame 602 through multiple sets of water distribution pipes 606. During the flow of tailings slurry through the guide water distribution frame 602, it relies on the five sets of staggered arrangement within the frame. The diversion column 603 achieves multi-stage diversion and flow stabilization, and the continuous slight wave-shaped curved surface at the bottom of the frame further dissipates the kinetic energy of the water flow; at the same time, the outlet end of the guide water distribution frame 602 is immersed below the surface of the thickening tank 1, and the underwater submerged water distribution method is adopted to completely avoid the impact and disturbance of high-speed water flow on the settling flocs in the tank, so that the tailings slurry diffuses into the water body of the thickening tank 1 at a low speed, evenly and steadily, so that the tailings solid particles settle fully under the action of gravity, and the clear water floats and separates, achieving efficient solid-liquid sedimentation operation; During operation, the drive motor 702 drives the rotating cylinder 4 to rotate at a constant speed through the meshing of the drive gear 703 and the external gear ring 701. This synchronously drives the rake frames 501 and the water distribution frame 601 on both sides to rotate circumferentially, achieving uniform water distribution and continuous sludge scraping throughout the entire area. When the rake frame 501 rotates, the bottom scraper plate 503 moves in contact with the bottom contour of the thickener 1, scraping and collecting the sludge deposited at the bottom of the tank. The turbid mud and water splashed during the sludge scraping operation are quickly sucked up by the inclined suction ports 504 distributed in a rectangular array on both sides of the suction frame 502, and after being collected by the collection channel 505, it flows back to the built-in liquid guiding frame. 506; At the same time, the rotational power of the rotating cylinder 4 is transmitted to the transmission gear 521 through the built-in toothed ring 520 on the inner wall, and then drives the rotating shaft 515 and the guide cylinder 516 to rotate synchronously through the driven gear 522. Relying on the sliding cooperation between the guide bolt 518 and the wave guide groove 517, the rotational motion is converted into the vertical reciprocating motion of the slide block 513, which drives the piston rod 511 and the sealing piston 512 to pump at high frequency in the cylinder 510. The cylinder 510 moves upward to form a negative pressure to draw back the mud and water in the built-in liquid guide frame 506, and moves downward to generate positive pressure to pressurize the mud and water through the one-way valve and send it back to the water distribution tank 8.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
