Abstract
Description
Technical Field
[0001] This invention relates to the field of mining waste treatment equipment technology, specifically to a tailings pond tailings water clarification device. Background Technology
[0002] During the mining and processing of mineral resources, a large amount of tailings water containing tailings particles is generated. Direct discharge of this water will cause serious environmental pollution. Therefore, tailings water clarification is a critical step in mining production. Currently, tailings pond tailings water clarification mainly adopts sedimentation separation technology. Through sedimentation devices, solid particles in the tailings water are deposited under gravity to form a sedimentation layer, thereby achieving solid-liquid separation.
[0003] However, existing sedimentation clarification devices have significant technical problems in removing the sedimentation layer: traditional devices mostly use a single-cavity structure, and the removal of the sedimentation layer usually relies on methods such as scraping with scrapers or high-pressure water flushing. When scraping with scrapers, the friction and pushing action between the scraper and the bottom surface of the sedimentation tank can easily disturb the water, causing the settled fine particles to be resuspended in the supernatant; although high-pressure water flushing can quickly peel off the sedimentation layer, the impact of the water flow can destroy the stability of the sedimentation layer, causing a large number of particles to be remixed into the water, seriously reducing the effluent clarification effect.
[0004] Meanwhile, some facilities employ continuous dredging modes to improve efficiency. However, this prevents independent operation of settling and dredging processes, and the continuous disturbance exacerbates particle suspension, leading to excessive solids content in the clarified tailings water. This necessitates secondary treatment, increasing costs and energy consumption. Therefore, preventing the re-suspension of settled particles during settling layer removal is a critical challenge that needs to be addressed in current tailings dam tailings water clarification technology to promote green and sustainable development in mining operations.

[0016] Compared with the prior art, the present invention provides a tailings dam tailings water clarification device, which has the following beneficial effects:
[0017] 1. The device divides the settling tank into multiple independent sedimentation chambers by vertical plates, and each chamber operates independently without affecting the others; compared with the rotation and stirring of traditional sludge scrapers, this device uses movable plates to vertically squeeze and collect sediment, which will not disrupt the established settling balance and avoid particle resuspension.
[0018] 2. As the movable plate moves towards the waste outlet, it exerts a squeezing effect on the sediment, allowing the water in the sediment to be quickly discharged from the sedimentation chamber through the permeable holes of the permeable plate, thus achieving pre-dewatering of the sediment. The sludge discharged after squeezing has a significantly reduced water content, which not only reduces the load on subsequent dewatering equipment and reduces dewatering energy consumption, but also reduces the difficulty of sludge transportation and the risk of stockpiling, thereby improving the overall economic and environmental benefits of tailings treatment.

[0030] like Figures 1 to 5 As shown, the present invention discloses a tailings dam tailings clarification device, including a settling tank 1. Multiple vertical plates 3 are fixedly installed on the inner bottom surface of the settling tank 1. The multiple vertical plates 3 are arranged at equal intervals along the length of the settling tank 1. The settling tank 1 is divided into multiple independent sedimentation chambers by the multiple vertical plates 3. Each sedimentation chamber can independently carry out sedimentation and waste discharge operations without interfering with each other, thereby improving the overall treatment efficiency.
[0031] Each sedimentation chamber is topped with a fixed plate 2. One end of the fixed plate 2 is fixedly connected to a vertical plate 3 in the width direction, and the other end of the fixed plate 2 forms a sedimentation inlet. A permeable plate 6 is rotatably mounted on the other end of the fixed plate 2 via a shaft. The width of the permeable plate 6 is adapted to the width of the sedimentation inlet. Each permeable plate 6 has multiple permeable holes evenly distributed on it to drain water generated during the sediment compression process. A deflection assembly is installed on the sedimentation tank 1, which can drive multiple permeable plates 6 to rotate synchronously, thereby closing and opening the sedimentation inlet.
[0032] Each settling chamber has a waste discharge port 5 at its bottom, directly below the fixed plate 2. Each waste discharge port 5 is equipped with a sealing component that can reliably seal or open the waste discharge port 5. A movable plate 4 is slidably installed inside each settling chamber. The size of the movable plate 4 is adapted to the cross-section of the settling chamber. A reciprocating motion component is installed on the settling tank 1, which can drive multiple movable plates 4 to reciprocate horizontally in their respective settling chambers.
[0033] Specifically, the deflection assembly includes a first screw 8, a first motor 9, a gear 10, a threaded block 11, and a rack 12. The first screw 8 is rotatably mounted on the outer wall of the settling tank 1 via bearings, and the first motor 9 is fixedly mounted on the outer surface of the settling tank 1 via bolts. The output end of the first motor 9 is fixedly connected to one end of the first screw 8 via a coupling. Multiple gears 10, threaded blocks 11, and racks 12 are provided and matched with the number of permeable plates 6. Gears 10 are keyed and fixed to one end of the shaft of the permeable plate 6. A sealing ring is fitted at the connection between the shaft of the permeable plate 6 and the settling tank 1. The sealing ring is made of wear-resistant nitrile rubber. Its inner side is tightly fitted to the shaft of the permeable plate 6, and its outer side is fixedly connected to the wall of the mounting hole of the settling tank 1, effectively preventing the tailings slurry in the settling tank 1 from leaking from the connection. Threaded blocks 11 are slidably installed on the outer wall of the settling tank 1. One end of the first screw 8 passes through the interior of the threaded block 11 and is threadedly connected to the threaded block 11. Each threaded block 11 is fixedly installed with a rack 12 by welding. The rack 12 and gear 10 are in a meshing state. To ensure smooth movement of the threaded block 11, a track block 13 is fixedly installed on each threaded block 11 by bolts. A track groove 14 is fixedly installed on the outer surface of the settling box 1 by bolts. The track block 13 and the track groove 14 are slidably connected to form a guide structure.
[0034] The reciprocating motion assembly includes a second screw 15 and a second motor 16. The second motor 16 is bolted to the outer surface of the settling tank 1. The second screw 15 is rotatably mounted on the inner wall of the settling tank 1 via bearings. A nitrile rubber sealing ring is fitted at the connection between the second screw 15 and the settling tank 1, and the installation method of the sealing ring is the same as that at the first screw 8, achieving a reliable seal. One end of the second screw 15 is fixedly connected to the output end of the second motor 16 via a coupling. One end of the second screw 15 passes through the interior of multiple movable plates 4 and is threadedly connected to the movable plates 4. A slide rod 17 is fixedly installed inside the settling tank 1. The slide rod 17 is parallel to the second screw 15, and one end of the slide rod 17 passes through the interior of multiple movable plates 4 and is slidably connected to the movable plates 4, guiding the movement of the movable plates 4 and preventing them from rotating.
[0035] The sealing assembly includes a sealing plate 18, a sliding groove 20, a slider 21, an adapter 22, and an electric telescopic rod 23. One end of the sealing plate 18 is rotatably connected to the lower surface of the settling tank 1 via a hinge. A rubber gasket 19 is fixedly installed on the upper surface of the sealing plate 18 by adhesive. The size of the rubber gasket 19 is larger than the size of the waste outlet 5 to improve the sealing effect. The sliding groove 20 is fixedly installed on the lower surface of the sealing plate 18 by bolts. The slider 21 is slidably connected to the sliding groove 20. The adapter 22 is rotatably connected to the slider 21 via a pin. An mounting plate 7 is fixedly installed on the lower surface of the settling tank 1 by bolts. The fixed end of the electric telescopic rod 23 is rotatably connected to the mounting plate 7 via a pin, and the movable end of the electric telescopic rod 23 is rotatably connected to the adapter 22 via a pin.
[0036] The specific working process of this device in processing sediment is as follows: First, the first motor 9 drives the first screw 8 to rotate. Under the guidance of the track block 13 and the track groove 14, multiple threaded blocks 11 move synchronously along the axial direction of the first screw 8. The threaded blocks 11 drive the rack 12 to move, and the rack 12 drives the gear 10 meshing with it to rotate. The gear 10 drives the permeable plate 6 to rotate around the shaft until the permeable plate 6 completely seals the sedimentation inlet. Then, the second motor 16 drives the second screw 15 to rotate. Under the guidance of the slide rod 17, the movable plate 4 moves towards the waste outlet 5 along the vertical direction of the sedimentation chamber. The movable plate 4 moves as it passes through the sedimentation chamber. During the process, the sediment in the sedimentation chamber is squeezed, causing the water in the sediment to be discharged from the sedimentation chamber through the permeable holes on the permeable plate 6, thus achieving dehydration. When the top of the movable plate 4 is in contact with the lower surface of the fixed plate 2 and the bottom of the movable plate 4 is located on one side of the waste discharge port 5, the second motor 16 stops working, and the movable plate 4 stops moving. Then, the movable end of the electric telescopic rod 23 retracts, pulling the slider 21 to slide in the slide groove 20 through the adapter 22, thereby driving the sealing plate 18 to rotate downward around the hinge, opening the waste discharge port 5. The dehydrated sediment concentrated above the waste discharge port 5 then leaves the sedimentation chamber under its own gravity, completing the waste discharge operation. After the waste discharge is completed, the movable end of the electric telescopic rod 23 extends, driving the sealing plate 18 to reset, and the rubber gasket 19 to fit with the waste discharge port 5 to achieve a seal. Then, the movable plate 4 and the permeable plate 6 reset, and the next round of sedimentation treatment cycle begins.
