[0004] To address the shortcomings of existing technologies, this utility model provides a micro-fine tailings dewatering device for lead ore processing. It solves the problem that simply using a conveyor belt for step-by-step dewatering still results in a high water content in the final tailings, which requires a large amount of heat to evaporate the water during tailings refining, thus leading to waste.

[0009] Preferably, the bottom of the side of the sedimentation tank is provided with a receiving cavity communicating with its interior, a receiving plate is slidably installed in the receiving cavity, a second T-shaped block is fixedly connected to the lower surface of the receiving plate, and a second T-shaped groove matching the second T-shaped block is provided at the bottom of the receiving cavity.

[0012] Beneficial effects

[0013] This invention provides a micro-fine tailings dewatering device for lead ore processing. Compared with the prior art, it has the following advantages:

[0014] (1) The fine tailings dewatering device for lead ore processing is equipped with multiple sedimentation tanks. The tailings are settled in each sedimentation tank in stages. A buffer plate is fixedly installed in the middle of the sedimentation tank. The buffer plate has a grid structure, which allows the tailings mixed in the water to settle through the grid of the buffer plate and enter the bottom of the sedimentation tank. The buffer plate also reduces the flow speed of the water below the buffer plate when the water flows, thus preventing the flowing water from stirring up the settled tailings and reducing the sedimentation efficiency.

[0015] (2) The fine tailings dewatering device for lead ore processing is equipped with a dewatering device. After the water passes through the sedimentation tank, it flows into the dewatering device. By rotating the water-throwing tank, the water is thrown out after passing through the filter element. The tailings are left to be stored in the water-throwing tank, thereby reducing the water content in the tailings. If the water content in the tailings after sedimentation is high, it can also be poured into the dewatering device for further dewatering. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a fine-grained tailings dewatering device for lead ore processing, comprising multiple interconnected sedimentation tanks 1, with a water discharge gate 3 between the sedimentation tanks 1, the water discharge gate 3 being able to adjust the height of the water flow between adjacent sedimentation tanks 1, the sedimentation tank 1 located at the tail end being connected to a dewatering device 4 via a water pipe 15, a water-throwing tank 42 being rotatably installed inside the dewatering device 4, the periphery of the water-throwing tank 42 having a grid-like double-layer structure, and a filter element with a ring structure being filled inside the double-layer structure of the water-throwing tank 42.

[0023] Specifically, multiple sedimentation tanks 1 are set up, and the tailings are settled in each sedimentation tank 1 in stages. A buffer plate 24 is fixedly installed in the middle of the sedimentation tank 1. The buffer plate 24 has a grid structure, which allows the tailings mixed in the water to settle through the grid of the buffer plate 24 and enter the bottom of the sedimentation tank 1. The buffer plate 24 also reduces the flow speed of the water below the buffer plate 24 when the water flows, thus preventing the flowing water from stirring up the settled tailings and reducing the sedimentation efficiency.

[0024] Water from the sedimentation tank 1 flows into the dewatering device 4, which is equipped with a dewatering device 4. The water is then thrown out by the rotation of the water-throwing tank 42, which is blocked by the filter element. The tailings are left to be stored in the water-throwing tank 42, thereby reducing the water content in the tailings. If the water content in the tailings is high after sedimentation, it can also be poured into the dewatering device 4 for further dewatering. The filter element filters the tailings, so that when the water-throwing tank 42 rotates, the water can be thrown out while the tailings are retained in the water-throwing tank 42.

[0025] The top of the connection between the two sedimentation tanks 1 is provided with a through groove that runs through both sides. The inner walls on both sides and the inner wall at the bottom of the through groove are provided with slots 13 that match the water gate 3. The water gate 3 includes a baffle 31, and the side of the baffle 31 is provided with a water flow channel 311.

[0026] Specifically, the height of the water trough 311 can be adjusted by sliding the baffle 31 up and down, thereby allowing the height to be adjusted according to the sedimentation height of the tailings in the sedimentation tank 1, preventing the sedimented tailings from flowing out of the sedimentation tank 1 with the flow of water.

[0027] Both sides of the baffle 31 are fixedly connected to the first T-shaped block 34. The inner wall of the slot 13 is provided with the first T-shaped groove 14 that matches the first T-shaped block 34. The top of the baffle 31 is fixedly connected to the connecting plate 32. Both ends of the upper surface of the connecting plate 32 are rotatably connected to the adjusting bolt 33. The end of the adjusting bolt 33 passes through the connecting plate 32 and is threadedly connected to the sedimentation tank 1.

[0028] Specifically, with the cooperation of the first T-shaped block 34 and the first T-shaped groove 14, the baffle 31 slides stably in the slot 13. By rotating the adjusting bolt 33, the baffle 31 is driven to make corresponding height adjustments under the action of the thread.

[0029] The adjusting bolt 33 is fixedly connected to a T-shaped ring block on the periphery of the connecting plate 32 through the connecting plate 32, and the inner wall of the connecting plate 32 is provided with a T-shaped ring groove that matches the T-shaped ring block.

[0030] Specifically, the combined use of the T-shaped ring block and the T-shaped ring groove allows the adjusting bolt 33 to be rotatably connected to the connecting plate 32, and also allows the connecting plate 32 to be adjusted accordingly while the adjusting bolt 33 changes its height.

[0031] The bottom of the side of the sedimentation tank 1 is provided with a receiving cavity 11 that communicates with its interior. A receiving plate 21 is slidably installed in the receiving cavity 11. A second T-shaped block 22 is fixedly connected to the lower surface of the receiving plate 21. A second T-shaped groove 12 that matches the second T-shaped block 22 is provided at the bottom of the receiving cavity 11.

[0032] Specifically, a receiving device 2 is provided in the receiving cavity 11. The receiving device 2 includes a receiving plate 21, which is slidably installed in the receiving cavity 11. The precipitated tailings are stored on the receiving plate 21. With the cooperation of the second T-shaped block 22 and the second T-shaped groove 12, the receiving plate 21 can slide stably in the receiving cavity 11, thereby driving the precipitated tailings out of the settling tank 1.

[0033] A storage cavity 23 is provided on the upper surface of the receiving plate 21. A buffer plate 24 is fixedly installed in the sedimentation tank 1 above the receiving plate 21. The buffer plate 24 is specifically a grid structure.

[0034] Specifically, the settled tailings are stored in the storage cavity 23 on the receiving plate 21. The buffer plate 24 provides some obstruction to the flowing water, reducing the flow speed of the water below the buffer plate 24 and preventing the water flow from impacting and causing the settled tailings to float again.

[0035] The dehydration device 4 also includes a storage tank 41, and a water-spinning tank 42 is located in the middle of the storage tank 41 and suspended by a connecting bracket 43. A rotating plate is rotatably mounted on the upper surface of the connecting bracket 43, and the water-spinning tank 42 is placed on the upper surface of the rotating plate. A plurality of positioning pins 45 are fixedly connected to the upper surface of the rotating plate, and the ends of the positioning pins 45 are slidably inserted into the water-spinning tank 42. A motor 44 is fixedly mounted on the lower surface of the connecting bracket 43, and the output shaft of the motor 44 is fixedly connected to the rotating plate.

[0036] Specifically, the storage tank 41 stores the separated water, and the motor 44 drives the rotating plate to rotate. Under the action of the positioning pin 45, the rotating plate drives the water-spinning tank 42 to rotate synchronously.
