Description

Technical Field

[0001] This invention relates to the field of tailings dam drainage technology, and in particular to a tailings dam beach surface drainage device. Background Technology

[0002] The phreatic line of a tailings dam is the lifeline of the tailings pond and is directly related to the safety and stability of the dam. Therefore, to ensure that the phreatic line depth meets the design requirements, it is common practice to add drainage wells to lower the phreatic line. Conventional tailings dam drainage facilities mainly include three types: horizontal drainage, vertical drainage, and a combination of horizontal and vertical drainage.

[0003] The vertical drainage system within the reservoir requires specialized equipment to drill holes in the soft sandy surface. Drainage pipes are then installed within these holes, completing the drainage system's operation. Typically, seepage is discharged directly through a short section (approximately 1 meter) of drainage pipe pre-installed at the wellhead, flowing onto the nearby sandy surface. The seepage then travels with the sandy surface towards the tail end of the reservoir, ultimately being pumped back to the concentrator as part of the return water.

[0004] However, while this method can drain seepage, it often encounters the following problems in practical applications: as tailings are continuously discharged into the dam, the tailings dam surface gradually rises, and the originally reserved section of the drainage pipe may be buried by the slurry, ultimately rendering the drainage well unusable. Adding a float to the extension pipe is considered; the float, buoyed by the slurry, will gradually rise with the dam surface to avoid the risk of burial. However, while this method can be effective in warmer regions, in extremely cold regions, especially those below -35°C, the drainage pipe fixed to the float will freeze in winter, rendering the drainage well ineffective. Even adding insulation to the outside of the drainage pipe is insufficient to withstand the extreme cold and ensure its normal operation. Summary of the Invention

[0005] The purpose of this invention is to provide a tailings dam beach surface collection and drainage device that can ensure that the floating body can rise with the beach surface even in cold winter, ensuring the normal operation of the drainage pipe assembly and making it more adaptable to extremely cold climate conditions.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] A first aspect of the present invention provides a tailings dam surface drainage device, such as... Figures 1 to 3 As shown, it includes a floating body device 1, a pipe-laying and transfer device 2, and a solar power supply device 3; The floating device 1 includes a floating body 11 that rises with the beach surface; The pipe-laying and draining device 2 is installed on the float 11. The pipe-laying and draining device 2 includes at least a partially spirally extended drain pipe assembly 21 and an antifreeze component 22 for heating the drain pipe assembly 21. The inlet of the drain pipe assembly 21 is configured to communicate with the drainage well 4, and the outlet of the drain pipe assembly 21 extends to the bottom of the float 11. The solar power supply device 3 is installed on the float 11, and the solar power supply device 3 is electrically connected to the antifreeze component 22 at least.

[0025] The tailings dam beach surface drainage device provided by this invention has a closed inner cavity for the float 11. When placed on the soft beach surface of the tailings dam, it can float completely on the beach surface. As the tailings dam beach surface gradually rises with the continuous discharge of ore in front of the dam, the float 11 also rises continuously due to the buoyancy of the ore slurry. The spiral extension of the drainage pipe assembly 21 gradually straightens, realizing the release of the pipe and adapting to the change in the height of the float 11, continuously discharging the seepage water in the drainage pipe assembly 21. During this process, the antifreeze component 22 for heating the drainage pipe assembly 21 is provided in the pipe release and transfer device 2, which can prevent the seepage water from freezing in the drainage pipe assembly 21. At the same time, the drain outlet of the drainage pipe assembly 21 can discharge the heated seepage water to the bottom of the float 11, and the seepage water flows towards the tail of the dam. At the same time, the temperature of the seepage water is used to maintain the temperature around the float at no lower than 0°C, ensuring that the bottom of the float does not freeze. Even in cold winter, it can rise with the rise of the beach surface.

[0026] Therefore, the above-mentioned tailings dam beach surface drainage device can be continuously raised as the tailings dam beach surface rises, ensuring the continuous drainage capacity of the drainage pipe group 21. In winter, the heated seepage water can be discharged to the bottom of the float 11 to ensure that the bottom of the float 11 does not freeze. Even in cold winter, it can be raised as the beach surface rises to ensure the normal operation of the drainage pipe group 21, making it more adaptable to extremely cold climate conditions.

[0027] The float 11 can be assembled from commonly used floating units of length*width*height=50cm*50cm*40cm or other sizes. The required bearing area of ​​the float 11 is calculated based on the weight of the device that the surface of the float 11 needs to support, and the number of floating units required is finally determined. Multiple floating units can be fixed together using a locking mechanism.

[0028] Of course, the float 11 can also be made into a one-piece structure.

[0029] In use, the float 11 is typically positioned near the drainage well 4. To ensure the stability of the horizontal position of the float 11, in optional embodiments, such as... Figure 1 As shown, the floating device 1 also includes a guide assembly 12, which is configured to be inserted into the tailings, and the floating body 11 slides in cooperation with the guide assembly 12 in the vertical direction.

[0030] During use, as the beach surface rises, the float 11 will also rise. Due to the function of the guide component 12, the float 11 can only move up and down along the guide component 12, which effectively reduces the float 11 from drifting and swaying on the beach surface during the upward rise, and ensures that the float 11 and the drainage well 4 are relatively fixed.

[0031] Specifically, the guide assembly 12 may include multiple guide rods, such as two, three, four, or more guide rods. Correspondingly, the float 11 is recessed with multiple guide holes, the diameter of which is larger than the outer diameter of the guide rods, and the multiple guide holes are slidably engaged with the multiple guide rods one by one. The guide holes are preferably distributed at the edge of the float 11 so as not to hinder the installation of other devices on the float 11.

[0032] The guide rod can be made of solid metal tube or angle steel. During installation, the guide rod can be inserted downward into the soft beach tailings for 2-3m to keep it upright.

[0033] As the beach surface rises, a method of connecting internal and external threads can be considered later to connect other rods to the top of the guide rod, thereby increasing the vertical length of the guide assembly 12.

[0034] In an alternative embodiment, the cross-sectional area of ​​the float 11 in the horizontal plane decreases as the height decreases; for example, the float 11 takes the form of a frustum that is wider at the top and narrower at the bottom.

[0035] Considering that in frigid regions or when tailings on the beach freeze in winter, the ice layer will exert a lateral squeezing effect on the float 11, the above embodiment designs the outer periphery of the float 11 as a slope with a certain gradient. When subjected to the squeezing force of ice, the slope will decompose into an upward lifting force, which will "squeeze" the float 11 upward and prevent the surface ice layer from freezing and locking the float 11 or even flattening it.

[0036] In an optional embodiment, the outer surface of the float 11 is provided with a buffer layer.

[0037] The buffer layer prevents the outer surface of the float 11 from directly contacting the ice layer, thus protecting the float 11.

[0038] The material of the aforementioned buffer layer may be, but is not limited to, high-density polyethylene.

[0039] When in use, the compressive elasticity of the above-mentioned materials can be used to absorb the lateral pressure generated by the expansion of the ice layer, so as to avoid direct contact between the float 11 and the ice layer and prevent the ice from causing structural compression damage to the float 11.

[0040] In an optional embodiment, the drain pipe assembly 21 includes a first drain pipe 211, a second drain pipe 212, and a third drain pipe 213. The three drain pipes can be connected in sequence to achieve mutual communication, or they can be connected through other structures.

[0041] The first drainage pipe 211 has an inlet at one end that is connected to the seepage well 4, the second drainage pipe 212 is connected between the first drainage pipe 211 and the third drainage pipe 213, and the third drainage pipe 213 has a drainage outlet that extends to the bottom of the float 11.

[0042] In an optional embodiment, the pipe-laying and transfer device 2 further includes a cylinder 23 and a support 24, with the support 24 installed on the float 11 to support the cylinder 23.

[0043] The outer surface of the cylinder 23 is provided with an opening 231, which facilitates the connection between the first drain pipe 211 and the second drain pipe 212; the two ends of the cylinder 23 along the axial direction are provided with a first hollow shaft 232 and a second hollow shaft 233 that are rotatably connected to the bracket 24 through bearings. The second drain pipe 212 is located inside the cylinder 23. One end of the second drain pipe 212 is located at the opening 231 and is connected to one end of the first drain pipe 211 outside the cylinder 23. The other end is connected to the first hollow shaft 232. The first hollow shaft 232 rotates and is sealed to one end of the third drain pipe 213 outside the cylinder 23.

[0044] In use, one end of the first drainage pipe 211 is fixedly connected to the drainage well 4, and the other end is spirally wound around the outside of the cylinder 23. As the float 11 rises, the distance between the cylinder 23 and the drainage well 4 increases. Under the pull of the first drainage pipe 211, the cylinder 23 rotates relative to the support 24, realizing the unwinding of the first drainage pipe 211 until the beach surface rises to its highest point, at which point the first drainage pipe 211 is completely released. During the above process, if... Figure 3 As shown, the seepage water in the drainage well 4 enters the second drainage pipe 212 through the first drainage pipe 211, and then enters the first hollow shaft 232 through the second drainage pipe 212. Since the first hollow shaft 232 and the third drainage pipe 213 rotate and are sealed together, the seepage water can still be transferred to the third drainage pipe 213 when the first hollow shaft 232 rotates relative to the third drainage pipe 213, and is finally discharged through the third drainage pipe 213.

[0045] The above-mentioned sealing effect can be achieved by sealing components such as rubber rings.

[0046] It is understandable that the combined structure at the connection between the first hollow shaft 232 and the third drain pipe 213 can adopt an existing mechanically sealed rotary joint.

[0047] Specifically, such as Figure 4 As shown, the second drainage pipe 212 includes a radial extension section 2121 and an axial extension section 2122 with an integral structure. One end of the radial extension section 2121 can be fixed at the opening 231 and fixedly connected to the end of the first drainage pipe 211 away from the seepage well 4 through a joint. The other end is connected to the axial extension section 2122. The end of the axial extension section 2122 away from the radial extension section 2121 is fixedly connected to the first hollow shaft 232, which can be done by welding.

[0048] The above configuration ensures that when the cylinder 23 rotates, the second drain pipe 212 and the first hollow shaft 232 rotate around the axis in a relatively static manner, so that after the seepage water enters the second drain pipe 212, the seepage water is rotated to the same direction as the axis of the cylinder 23 and then discharged, and the discharge of the seepage water is not affected by the rotation of the cylinder 23.

[0049] In an optional embodiment, the outer surface of the cylinder 23 is provided with a spiral groove, and the first drain pipe 211 is wound around the outside of the cylinder 23 along the spiral groove.

[0050] In the above embodiment, a spiral groove is provided on the outer circumferential surface of the cylinder 23 along the winding path of the drain pipe to facilitate the placement of the first drain pipe 211 in a designated position, so as to avoid the first drain pipe 211 from shifting after winding. The relative position of two adjacent turns of the first drain pipe 211 is relatively stable and the fit is high.

[0051] Specifically, the size of the spiral groove can be set according to the diameter of the first drain pipe 211.

[0052] The first drainage pipe 211 can be made of HDPE pipe.

[0053] In extremely cold environments, the first drain pipe 211 wound around the cylinder 23 may freeze inside due to incomplete drainage of internal water. Therefore, an antifreeze component 22 is designed to prevent the first drain pipe 211 wound around the cylinder 23 from freezing.

[0054] In alternative implementations, such as Figure 3 and Figure 4 As shown, the antifreeze component 22 includes a heat tracing cable 221, a wire 222, and an electric slip ring 223. The heat tracing cable 221 is attached to the inner wall of the cylinder 23. One end of the wire 222 is electrically connected to the heat tracing cable 221, and the other end passes through the second hollow shaft 233 and is connected to the rotor end of the electric slip ring 223. The stator end of the electric slip ring 223 is connected to the battery 31 in the solar power supply device 3, and the battery 31 is connected to the first solar panel 32 in the solar power supply device 3.

[0055] If the heat tracing cable 221 is directly connected to the first drain pipe 211, the heat tracing cable 221 may accumulate high temperatures and cause the first drain pipe 211 to be damaged, or water leakage from the first drain pipe 211 may cause a short circuit in the heat tracing cable 221. The above embodiment attaches the heat tracing cable 221 to the inner wall of the cylinder 23, avoiding a direct connection between the heat tracing cable 221 and the first drain pipe 211.

[0056] When the heating cable provides heat, the heat first evenly heats the cylinder 23. After the cylinder 23 is heated, it evenly transfers the heat to the first drain pipe 211 on the outer wall. This avoids the aforementioned adverse situations and also ensures that the first drain pipe 211 is heated evenly. In addition, the heat from the heating cable 221 is stored inside the cylinder 23, preventing heat loss.

[0057] Specifically, the heat tracing cable 221 can be wound and pasted on the inner wall of the cylinder 23 in the same direction as the first drain pipe 211. One end of the cable is pasted on one side of the inner wall of the cylinder 23, and the other end is connected to the wire 222. The wire 222 passes through the second hollow shaft 233 and is connected to the rotor end of the electric slip ring 223. The rotor end of the electric slip ring 223 is fixedly installed on the second hollow shaft 233. The stator end of the electric slip ring 223 and the rotor end are rotatably engaged and electrically connected. The battery 31 in the solar power supply device 3 is connected to the stator end of the electric slip ring 223.

[0058] When the cylinder 23 rotates, the rotor end of the wire 222 and the slip ring 223 rotates accordingly, while the stator end of the slip ring 223 remains fixed and connected to the battery 31, so as to realize the stable power supply from the battery 31 to the wire 222 and avoid signal interruption or device damage caused by the wire 222 being tangled.

[0059] Since the float 11 is located inside the tailings dam, in order to facilitate power supply to the heating cable 221, the battery 31 is connected to the first solar panel 32 in the solar power supply device 3, and the electricity converted from solar energy is stored in the battery 31.

[0060] In alternative implementations, such as Figure 5 As shown, the pipe discharge and transfer device 2 also includes a mounting frame 25 and a water-air separator 26. The third drain pipe 213 is installed on the mounting frame 25, and the water-air separator 26 is installed on the third drain pipe 213.

[0061] The aforementioned mounting bracket 25 provides fixed support for the third drain pipe 213 and can be connected to the bracket 24.

[0062] Existing drainage methods include siphon drainage, air-driven drainage, and pump drainage. Air-driven drainage often generates a large amount of gas during drainage. In order to facilitate accurate measurement of subsequent water volume, the above embodiment is equipped with a water-air separator 26. The water-air separator 26 separates the gas in the water so that the air in the water is discharged before the water is drained, ensuring that there is no air in the discharged water.

[0063] Specifically, the water-air separator 26 is equipped with a horizontal inlet and a horizontal outlet. An exhaust port is located directly above the separator, and a vent valve is located directly below it. When gas-containing material enters the water-air separator 26, it first settles within the separator. When the liquid level reaches the outlet, seepage begins to drain, while the air in the water is discharged through the exhaust port. In case of abnormal operating conditions, the vent valve at the bottom is opened to release the remaining liquid in the water-air separator 26. Additionally, if tailings sediment accumulates in the separator, the vent valve can also be opened to drain the sediment.

[0064] To ensure the stability of the water-air separator 26, a triangular bracket is installed below the water-air separator 26 and connected and fixed to the float 11, thus ensuring the stability of the water-air separator 26.

[0065] In alternative implementations, such as Figure 5 As shown, the pipe discharge and transfer device 2 also includes a flow meter 27, a second solar panel 28, and a data transmitter connected to the flow meter 27. The flow meter 27 is installed on the third drain pipe 213, and the second solar panel 28 is installed on the flow meter 27 and provides power to the flow meter 27 and the data transmitter.

[0066] After the seepage water is separated by the water-air separator 26, it enters the flow meter 27 through the third drainage pipe 213. The flow meter 27 can measure the drainage volume of the seepage well 4.

[0067] Since tailings dams are generally located in relatively remote areas, and the flow meter 27 is located inside the dam, it is difficult and unsafe to run a separate line from the tailings dam body to the distant floating body 11 inside the dam. Therefore, the above implementation method uses solar power (or a combination of solar and wind power) to provide power to the flow meter 27 and the data transmitter, and wirelessly feeds back the data detected by the flow meter 27 to the remote control system.

[0068] Considering the instability of 4G network signals in remote areas, existing LoRa (Long Range) wireless communication technology can be used. This involves installing a LoRa data transmitter on the flow meter 27, transmitting the collected flow data to a remote LoRa data receiver via a local area network, and finally transmitting the data to the control system. This wireless transmission method can ensure smooth data transmission even in remote areas without network access.

[0069] like Figure 5 As shown, the third drain pipe 213 extends from the flow meter 27 and includes a main pipe 2131 and multiple branch pipes 2132. The main pipe 2131 is arranged around the flow meter 27, the water-air separator 26 and the support 24. One end of each branch pipe 2132 is connected to the main pipe 2131, and the other end passes through the float 11 and extends below the float 11.

[0070] Understandably, the float 11 is provided with holes for the branch pipe 2132 to pass through.

[0071] In alternative implementations, such as Figure 6 As shown, the tailings dam beach surface drainage device also includes a turbulence pipe 5. One end of the turbulence pipe 5 is configured to be connected to the high-pressure air source of the drainage well 4, and the other end is wrapped around the outer periphery of the float 11 and is provided with a jet nozzle. The jet nozzle is located on the side of the turbulence pipe 5 away from the float 11, and the jet nozzle sprays air towards the side and / or bottom of the float 11.

[0072] In the above embodiment, the turbulence pipe 5 has different small holes, and high-pressure gas is used to form fine bubbles around and / or at the bottom of the float 11. Forced convection continuously disturbs the water around the float 11, destroying the physical structure of ice crystal formation. Under the combined action of seepage water above 0°C and high-pressure gas, the bottom of the float 11 is prevented from freezing, so that the float 11 will not freeze even in cold winter and can rise with the rise of the beach.

[0073] Since the seepage water in the drainage well 4 is lifted and discharged by a pre-set high-pressure gas, the high-pressure gas used in the turbulence pipe 5 is only used to turbulent the bottom of the float 11 by dividing a small portion of the high-pressure gas used for drainage. In addition, the high-pressure gas delivered by the air compressor generally carries a certain temperature, which is more conducive to antifreeze.

[0074] In alternative implementations, such as Figure 6 As shown, the tailings dam beach surface drainage device also includes a transparent protective heat insulation cover 6. The protective heat insulation cover 6 is installed on the float 11 and forms a space between the cover and the float 11 for installing the pipe discharge and transfer device 2 and the solar power supply device 3.

[0075] The protective insulation cover 6 not only increases the insulation effect, but also avoids the impact of natural phenomena such as rain, snow, wind and sand on the entire device.

[0076] Specifically, the protective heat insulation cover 6 includes a first cover 61 and a second cover 62, both installed on the float 11. The first cover 61 covers the outside of the pipe discharge and transfer device 2, and the second cover 62 covers the outside of the solar power supply device 3.
