Description

Technical Field

[0001] The invention relates to the field of drainage, and in particular to a device and method for reducing blockage of a drainage well of a tailings pond. Background Art

[0002] The drainage well of the tailings pond is used to control and manage the water level and water quality inside the tailings pond. It is mainly used to discharge the water accumulated in the tailings pond to maintain a suitable water level and reduce the water pressure in the reservoir, effectively preventing overflow or structural safety problems caused by excessively high water levels. When necessary, the water quality of the tailings pond is monitored through the drainage well to ensure that the discharged water quality meets environmental requirements. Through timely drainage and water quality control, the safety risks that occur during the operation of the tailings pond can be reduced. However, the drainage well has the risk of blockage. Once the drainage well is blocked, the accumulated water in the tailings pond cannot be discharged in time, causing the water level to continue to rise. When the water level rises to a certain level, it will increase the dam pressure of the tailings pond, which may cause the dam to become unstable and even cause a dam breach.

[0003] Existing devices for reducing blockage of tailings pond drainage wells use a retaining system composed of buoy rings connected by buoys. The buoys float on the surface of the tailings water and surround the drainage wells, rising or falling synchronously with the water level. They are unable to intercept smaller impurities and have difficulty meeting higher water quality requirements inside the tailings pond. In addition, the devices have a relatively complex structure and are difficult to apply to large-scale use, which is not conducive to reducing costs and increasing efficiency.

[0004] Based on this, the existing technology is in urgent need of improvement. Summary of the invention

[0027] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are only illustrative.

[0028] Drainage wells can drain the water accumulated in the tailings pond to maintain a suitable water level and reduce the pressure of the water body in the reservoir. The water level of the tailings pond can be effectively controlled through drainage wells to prevent overflow or structural safety problems caused by excessively high water levels. At the same time, drainage wells are also used to manage the water quality of the tailings pond return water. When necessary, they can discharge, treat or monitor the water quality in the tailings pond to ensure that the discharge meets environmental standards and regulatory requirements. Drainage wells can also monitor the concentration of chemicals, suspended matter and other pollutants in the water and take appropriate treatment measures as needed. Drainage wells play an important role in the safety management of tailings ponds. They can prevent overflow events caused by excessively high water levels, and can also help monitor and manage the stability of the tailings pond structure. Through timely drainage and water quality control, the risks and safety hazards that may occur in the operation of the tailings pond can be reduced. Drainage wells are usually equipped with monitoring equipment for real-time monitoring of water levels, water quality and the operating status of equipment in the well. These data are very important for the operation, management and maintenance of tailings ponds, and can help staff to discover and solve problems in a timely manner to ensure the long-term and stable operation of tailings ponds.

[0029] Please refer to Figure 1 , Figure 1The device 100 for reducing the blockage of the tailings pond drainage well provided by the first embodiment of the present invention is shown. The device 100 for reducing the blockage of the tailings pond drainage well includes a floating interception net 3, which is arranged around the tailings pond drainage well 4 and is connected by a plurality of floats 1 and an interception net 2. The lower end of the interception net 2 is connected to a plurality of ballasts 5, and the ballasts 5 are used to make the interception net 2 located within a preset depth range under the water surface. It is understandable that the number of floats 1 and the number of ballasts 5 can be flexibly set according to actual conditions. For example, in Figure 1 There are four floats 1, which are respectively connected to the interception net 2, and four ballasts 5 are connected to the lower end of the interception net 2. Through the mutual cooperation between the floating interception net 3 and the multiple ballasts 5 connected to the lower end of the interception net 2, it is ensured that smaller impurities can be intercepted by the interception net 2, thereby meeting the higher requirements of water quality inside the tailings pond. At the same time, the structural design is simple, which is convenient for large-scale use and is conducive to reducing costs and increasing efficiency.

[0030] Please continue to refer to Figure 1 , multiple floats 1 are evenly distributed around the tailings pond drainage well 4. The floats 1 are evenly distributed around the tailings pond drainage well 4. On the one hand, the floats 1 themselves can block some debris floating on the water surface, such as branches, leaves, plastic garbage, etc., to prevent these debris from entering the drainage well 4, thereby reducing the blockage of the drainage well 4. On the other hand, multiple floats 1 are evenly distributed around the drainage well 4, which can guide and stabilize the water flow to a certain extent. The floats 1 and the interception net 2 cooperate with each other, reducing the number of original floats 1, and realizing the interception of smaller impurities to meet the higher requirements of water quality inside the tailings pond, which is conducive to reducing costs and increasing efficiency.

[0031] According to some embodiments of the present invention, the number and size of the floats 1 are adapted to the size of the tailings pond drainage well 4. The shape of the floats 1 includes but is not limited to round, square, etc. Figure 1 As shown, the shape of the float 1 is square, and the size and number of the float 1 are flexibly selected according to the scale and actual needs of the drainage well 4. By reasonably controlling the number and size of the floats 1, the float 1 and the interception net 2 can completely surround the drainage well 4, ensuring that there is no missed area, better matching the surrounding contour of the drainage well 4, and achieving all-round protection. At the same time, the number of floats 1 can be reduced as much as possible to avoid excessive number and reduce the cost of replacement and maintenance.

[0032] According to some embodiments of the present invention, the material of the float 1 is corrosion-resistant and buoyant. The float has buoyancy, which can provide support and positioning for the interception net 2, so that the interception net 2 is in a floating state. At the same time, since the water in the tailings pond usually contains various chemical substances, such as heavy metal ions, acid and alkali substances, etc., these substances are highly corrosive to ordinary materials, and the corrosion-resistant material of the float 1 can effectively resist the erosion of these chemical substances and will not be damaged due to long-term contact with the tailings pond water.

[0033] According to some embodiments of the present invention, the float 1 comprises a plastic float or a foam float.

[0034] According to some embodiments of the present invention, multiple floats 1 are connected to the interception net 2 by any of chains, ropes or buckles. The materials and manufacturing processes of the chain, rope or buckle connection are relatively simple, easy to purchase and process, and can reduce the overall construction and maintenance costs when applied on a large scale.

[0035] Please continue to refer to Figure 1 The interception net 2 is a mesh-shaped corrosion-resistant woven fabric, wherein the mesh size of the interception net 2 is 1-5 mm. The mesh size of 1-5 mm can intercept most of the debris that may enter the drainage well 4. Small particles of solid waste, branches and leaves, and mud and sand commonly found in the tailings pond can be blocked by the interception net 2, thereby preventing these debris from entering the drainage well 4 and causing blockage. At the same time, the interception net 2 is a mesh-shaped corrosion-resistant woven fabric, which can effectively increase the service life of the device.

[0036] Please continue to refer to Figure 1 The spacing between the multiple ballasts 5 is the same. The spacing between the multiple ballasts 5 is the same, ensuring that the interception net 2 is in a balanced state under the water surface, ensuring that the floating interception net 3 effectively intercepts small particles of impurities, so as to further improve the effect of intercepting impurities of the device for reducing the blockage of the tailings pond drainage well 4, and meet the higher requirements of the water quality inside the tailings pond.

[0037] According to several embodiments of the present invention, the quantity and volume of the ballast 5 are adapted to the preset depth range of the interception net 2 under the water surface. The ballast 5 is used to make the interception net 2 within the preset depth range under the water surface. According to the preset depth range of the interception net 2 under the water surface, the quantity and volume of the ballast 5 are determined to ensure that the interception net 2 can intercept smaller impurities to the greatest extent.

[0038] In order to further understand the device for reducing the blockage of the tailings pond drainage well of the present invention, another specific embodiment is described below. The device for reducing the blockage of the tailings pond drainage well is arranged around the drainage well. In actual production conditions, the drainage well is isolated from the water surface of the discharge end of the tailings pond by a float at an appropriate distance from the drainage well. Each float is connected in series using a rope with a certain elasticity, and a mesh-structured woven cloth (interception net) is arranged below the float. A heavy ball (ballast) is hung below the woven cloth. The woven cloth is straightened to balance the interception net, that is, to ensure that the interception net is in a balanced state under the water surface, so that the floating interception net can effectively intercept small particles of impurities, so as to further improve the effect of intercepting impurities of the device for reducing the blockage of the tailings pond drainage well, effectively prevent the debris, slurry foam and fish in the reservoir from entering the drainage well to prevent blockage, thereby improving the water quality of the return water from the drainage well in the reservoir, facilitating the use of return water, and meeting the higher requirements for water quality inside the tailings pond.

[0039] The above-mentioned device for reducing the blockage of the tailings pond drainage well of the present invention can effectively prevent large particles such as debris and silt from entering the drainage well, thereby ensuring the smooth flow of the drainage system and avoiding water flow obstruction or reduced drainage efficiency. Since debris entering the drainage system may damage water pumps, pipes and other equipment, the device for reducing the blockage of the tailings pond drainage well of the present invention can reduce the failure and damage caused by the entry of debris, thereby extending the service life of the equipment, reducing the frequency of maintenance and replacement, and reducing maintenance costs. The device for reducing the blockage of the tailings pond drainage well of the present invention can effectively reduce the entry of debris into the drainage system, and some debris may contain harmful substances or microorganisms, reducing pollution or impact on the surrounding environment and ecosystem. It can also reduce the occurrence of frequent cleaning of the drainage system due to blockage by debris, thereby improving the stability and efficiency of the drainage system.

[0040] According to the second aspect of the present invention, a method for reducing the blockage of the tailings pond drainage well is also provided, comprising: step a, arranging a device as described above around the tailings pond drainage well; step b, periodically lifting the floating interception net from a preset depth range under the water surface to the water surface, and removing impurities attached to the interception net. Through the mutual cooperation between the floating interception net and the multiple ballasts 5 connected to the lower end of the interception net, it is ensured that smaller impurities can be intercepted by the interception net, thereby meeting the higher requirements for water quality inside the tailings pond, and at the same time, the structural design is simple, convenient for large-scale use, and conducive to reducing costs and increasing efficiency.
