Description

Technical Field

[0001] This utility model relates to the field of pipeline dredging technology, specifically a tailings pipeline dredging device. Background Technology

[0002] Tailings are solid waste generated during the mining and beneficiation of mineral resources. They are the solid parts remaining after the useful components of the ore have been extracted through beneficiation operations. In subsequent beneficiation processes, a large amount of water is usually added, resulting in tailings having a high water content and appearing as a slurry.

[0003] In tailings pipeline transportation systems, blockages frequently occur due to the combined effects of various factors such as slurry concentration, tailings pump performance, and power supply. Traditional tailings pipeline dredging methods present numerous difficulties: dredging a blocked pipeline requires a complete shutdown of the entire ball mill workshop. Operators then need to make multiple cuts in the pipeline and use pumps to gradually clear the blockage. After each section is cleared, additional welds are required before repeating the process until the hydrocyclone is cleared. This method not only requires a large number of maintenance workers (usually 5-6 people) but also takes a long time, typically about 10 hours, sometimes even more than 24 hours. Furthermore, the complete shutdown significantly reduces the ball mill's operating rate, thereby decreasing iron concentrate production and causing substantial economic losses to the company. In addition, frequent starting and stopping of the tailings pumps also negatively impacts their service life.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a tailings pipeline dredging device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the tailings pipeline dredging device provided by this utility model includes a tailings pipeline, a box body, and a transmission pipeline. A vertically arranged partition plate is fixed at the center of the box body along its length direction. A diversion plate is rotatably connected to one end of the partition plate along its length direction. The diversion plate can be tightly abutted against the two inner side walls of the box body along its width direction. Filters with the same structure slide on both sides of the partition plate away from the diversion plate along its width direction. The length direction of the filter screen is perpendicular to the length direction of the partition plate. A horizontally penetrating channel is opened on each of the two outer side walls of the box body along its width direction, corresponding to the side of the two filters that are far apart from each other. A movable plate is fixed on the side wall of the two filters that are far apart from each other. The movable plate slides in the channel. A power storage mechanism is provided at the top of the rotatable connection between the diversion plate and the partition plate.

[0007] A hydrocyclone is fixed at the end of the tailings pipeline away from the box body. A conveying pipeline is fixed on the outer arc wall of the tailings pipeline. A tee is fixed at the end of the conveying pipeline away from the tailings pipeline. A vertical pump pipeline is fixed at one end of the tee.

The fixed shaft passes through the sealing cover and is fixed to the top of the diverter plate. An extension part is fixed on the outer arc wall of the rotating plate. A column is fixed on the side wall of the extension part away from the sealing cover away from the rotating plate. A fixed column is fixed on the top of the partition plate near the diverter plate. The same tension spring is sleeved on the outer arc wall of the fixed column and the column. Limiting columns are fixed on both sides of the outer arc wall of the rotating plate on the side of the top of the sealing cover near the partition plate. When the length direction of the extension part is perpendicular to the length direction of the partition plate, the extension part and the limiting column abut against each other.

[0009] Furthermore, a second rotating plate is fixed to the top of the first rotating plate away from the first extension. The second rotating plate includes a fixing part fixed to the top of the first rotating plate and extending radially along the first rotating plate. The second extension is fixed to both sides of the fixed part away from the first rotating plate along the width direction of the fixing part. The second extension has an arc-shaped cross section in the horizontal direction and the notch always faces the first rotating plate. The top and bottom of the filter screen are fixedly connected to both sides along its own length direction. A groove is opened on the inner side wall of the box corresponding to the position of the first sliding plate. The length direction of the groove is consistent with the length direction of the box. The first sliding plate slides in the groove. A horizontally arranged sealing plate is fixedly connected to the side wall of the first sliding plate away from the diverter plate near the opening of the corresponding groove. The top of the sealing plate is located inside the groove.

[0010] Furthermore, a horizontally arranged pull rod is fixed on the side wall of the slider 1 located at the top and near the partition plate, which is close to the diverter plate.

The top and bottom of the filter screen near the movable plate are both fixed with horizontally arranged slider 2. The slider 2 slides on the side wall of the movable plate near the filter screen.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting up a filter screen, larger particles that the hydrocyclone failed to screen out in the tailings can be effectively intercepted, reducing the risk of blockage in subsequent pipelines. When the filter screen becomes blocked, it will shift under the thrust of continuous transportation, which will trigger the energy storage mechanism, drive the diverter plate to turn, and guide the tailings into the transmission pipeline on the other side. This allows for uninterrupted operation without stopping the entire line during the process of clearing blocked pipelines, ensuring the continuity of production and avoiding the reduction in output and economic losses caused by a complete shutdown.

[0013] 2. High-pressure dredging of tailings pipelines using the vertical pump pipeline of the accident pool. Compared with traditional dredging methods, this device significantly improves dredging efficiency, reduces the number of operators, and greatly reduces dredging operation time.

[0023] 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.

[0024] Please see the appendix Figure 1 To be continued Figure 5 The tailings pipeline dredging device provided by this utility model includes a tailings pipeline 11, a box 20 and a transmission pipeline 21. A vertically arranged partition plate 37 is fixed at the center of the box 20 along its length direction. A diversion plate 36 is rotatably connected to one end of the partition plate 37 along its length direction. The diversion plate 36 can be tightly abutted against the two inner side walls of the box 20 along its width direction. Filters 23 with the same structure slide on both sides of the partition plate 37 away from the diversion plate 36 along its width direction. The length direction of the filter 23 is perpendicular to the length direction of the partition plate 37. A horizontally penetrating channel is opened on the two outer side walls of the box 20 along its width direction, corresponding to the side of the two filters 23 that are far apart from each other. A movable plate 22 is fixed on the side wall of the two filters 23 that are far apart from each other. The movable plate 22 slides in the channel. A power storage mechanism is provided at the top of the rotatable connection between the diversion plate 36 and the partition plate 37.

[0025] A storage slot is provided on the inner top wall of the housing 20 at the rotatable connection between the diverter plate 36 and the partition plate 37. A sealing cover is fixed at the opening of the storage slot. A power storage mechanism is set in the storage slot. The power storage mechanism includes a rotating plate 30 coaxially set at the rotatable connection between the diverter plate 36 and the partition plate 37. The rotating plate 30 is set on the side wall of the sealing cover away from the inside of the housing 20. A fixing shaft is coaxially fixed at the bottom of the rotating plate 30. The fixing shaft passes through the sealing cover and is fixed to the top of the diverter plate 36.

[0026] An extension portion 1 extending radially is fixed on the outer arc wall of the rotating plate 30. A column is fixed on the side wall of the extension portion 1 away from the sealing cover at the end away from the rotating plate 30. A fixing column 34 is fixed on the top of the partition plate 37 near the diversion plate 36. The same tension spring 33 is sleeved on the outer arc wall of the fixing column 34 and the column. Limiting columns 32 are fixed on both sides of the outer arc wall of the rotating plate 30 on the side of the top of the sealing cover near the partition plate 37. When the length direction of the extension portion 1 is perpendicular to the length direction of the partition plate 37, the extension portion 1 and the limiting column 32 abut against each other.

[0027] A hydrocyclone 10 is fixed at the end of the tailings pipe 11 away from the box 20. A conveying pipe is fixed on the outer arc wall of the tailings pipe 11. A tee pipe 14 is fixed at the end of the conveying pipe away from the tailings pipe 11. A vertical pump pipe 13 is fixed at one end of the tee pipe 14. An emergency pool 12 is provided at the end of the vertical pump pipe 13 away from the tee pipe 14. The vertical pump pipe 13 is buried in the emergency pool 12. A valve 15 is installed on the conveying pipe.

[0028] It should be noted that: the housing 20 provides installation space for the entire device, the partition plate 37 divides the interior of the housing 20 into two areas, which are used to install two filters 23 respectively, so that the two filters 23 can work independently. The diversion plate 36 rotates on the partition plate 37, which can guide the tailings to different filters 23. When one filter 23 is blocked, the diversion plate 36 rotates to switch to the other filter 23, ensuring the continuous filtration function of the device.

[0029] The power storage mechanism includes a rotating plate 30, a fixed shaft, a column, a fixed column 34, and a tension spring 33. The elastic force of the tension spring 33 provides power for the rotation of the diversion plate 36. When one side of the filter screen 23 is blocked, the filter screen 23 on that side is pushed and displaced under continuous transport, which in turn drives the pull rod 35 to pull the extension part 2. The extension part 2 drives the rotating plate 30, which in turn drives the extension part 1 to rotate. When the extension part 1 rotates, it pulls the tension spring 33 until the extension part 1 rotates to the other side. The rotating plate 30 drives the diversion plate 36 to rotate through the fixed shaft. The filter screen 23 is used to filter impurities in the tailings. The movable plate 22 is fixedly connected to the filter screen 23. The operator can remove the movable plate 22 to clean the impurities on the filter screen 23.

[0030] Please see the appendix Figure 1 To be continued Figure 5 The present invention provides a technical solution: a rotating plate 31 is fixed at the top of the rotating plate 30 away from the extension part 1. The rotating plate 31 includes a fixing part fixed to the top of the rotating plate 30 and extending radially along the rotating plate 30. Extension parts 2 are fixed on both sides of the fixing part away from the rotating plate 30 along the width direction of the fixing part. The cross section of the extension part 2 in the horizontal direction is arc-shaped and the notch is always facing the rotating plate 30.

[0031] The filter screen 23 has sliders 24 fixedly connected to both sides of its top and bottom along its length. The inner wall of the box 20 is provided with grooves corresponding to the positions of sliders 24. The length direction of the grooves is consistent with the length direction of the box 20. Slider 24 slides in the grooves. A horizontally arranged sealing plate 25 is fixedly connected to the side wall of slider 24 away from the diverter plate 36 near the opening of the corresponding groove. The top of the sealing plate 25 is located inside the groove.

[0032] A horizontally arranged pull rod 35 is fixed on the side wall of the slider 24 located at the top and near the partition plate 37, which is close to the diversion plate 36. The two pull rods 35 are located on both sides of the partition plate 37 along its width direction and are respectively facing the rotating plate 30 and the rotating plate 31. A barb is fixed at the end of the pull rod 35 away from the slider 24. The barb slides against the arc wall of the extension part 2 near the rotating plate 30. A horizontally penetrating arc groove is opened at the top of the extension part 1, and the barb at the end of the pull rod 35 can slide in the arc groove.

[0033] The top and bottom of the side wall of the filter screen 23 near the movable plate 22 are both fixed with horizontally arranged sliders 26, which slide on the side wall of the movable plate 22 near the filter screen 23.

[0034] It should be noted that: the tailings enter the box 20 from the tailings pipe 11, and after being guided by the diversion plate 36, they flow to the filter screen 23 on one side. The filter screen 23 filters the tailings and blocks the larger particles of impurities that the hydrocyclone 10 could not completely screen out, preventing them from entering the subsequent equipment and causing blockage or even damage. Water and fine mineral sand enter the transmission pipe 21 through the filter screen 23.

[0035] As filtration proceeds, impurities gradually accumulate on the filter screen 23, leading to a decrease in filtration efficiency. When one side of the filter screen 23 becomes clogged, the filter screen 23 shifts under continuous transport, which in turn pulls the lever 35, causing the diverter plate 36 to rotate under the action of the power storage mechanism, thus putting the filter screen 23 on the other side into operation. In the power storage mechanism, the lever 35 pulls the extension part 2 to pull the rotating plate 2 31, which in turn pulls the rotating plate 1 30 to rotate. Subsequently, the tension spring 33 pulls the rotating plate 1 30 to rotate. When the extension part 1 rotates to a state parallel to the partition plate 37, if the extension part 1 continues to rotate, the tension spring 33 will have a tendency to retract, thus pulling the column. The rotating plate 1 30 drives the diverter plate 36 to rotate, and the diverter plate 36 switches from a state of tight contact with the inner wall of one side of the housing 20 to a state of tight contact with the inner wall of the other side.

[0036] Then, the staff can pull the movable plate 22 out of the channel and take out the corresponding filter screen 23 to clean the impurities on the filter screen 23. The staff can also check the inside of the box 20 from one of the channels to see if it needs to be cleared and decide whether to open the valve 15 for high-pressure flushing and clearing. When high-pressure clearing is required, first fill the emergency pool 12 with water and then turn on the vertical pump pipe 13 to clear the pipeline. Open the corresponding valve 15 and then disconnect the pump outlet of the corresponding pump station. The material blocking the pipeline will be flushed down until the water flows out smoothly and the pipeline is cleared.

[0037] Working principle:

[0038] Tailings enter the box 20 through tailings pipe 11 and flow to one side filter screen 23 under the guidance of diversion plate 36. Filter screen 23 filters out larger particles of impurities, while water and fine mineral sand enter the transmission pipe 21. As filtration proceeds, one side filter screen 23 becomes clogged, causing the filter screen 23 to shift and pull the pull rod 35. The barb at the end of the pull rod 35 slides against the extension of the second rotating plate 31, causing the first rotating plate 30 to rotate. The tension spring 33 is stretched. When the extension rotates to be parallel with the partition plate 37, it continues to rotate. The tension spring 33 retracts and pulls the first rotating plate 30, which drives the diversion plate 36 to rotate through the fixed shaft, switching to the other side filter screen 23 for operation.

[0039] At this time, the staff can pull out the movable plate 22 to clean the impurities on the clogged filter screen 23, and also check whether the inside of the box 20 needs to be cleared. If it needs to be cleared, fill the emergency pool 12 with water, turn on the vertical pump pipe 13, open the valve 15, remove the pump outlet short circuit, and the high-pressure water flow will flush down the material in the pipeline until the water flows out smoothly, thus completing the clearing.
