Description

Technical Field

[0001] This utility model belongs to the field of mineral processing technology, and in particular relates to a water system for preventing freezing and clogging of tailings dam spillway towers. Background Technology

[0002] Tailings dam spillways are crucial drainage and water return structures in mineral processing tailings dams. They primarily regulate water levels within the tailings dam, ensuring continuous mine production and safe drainage during flood season. During tailings dam operation, the spillway's window-type structure allows for flexible adjustment of drainage volume, ensuring stable water return during production to meet recycling needs. Simultaneously, it efficiently drains water during flood season, preventing excessively high tailings dam water levels and playing a vital safety regulation role. The spillway's window-type design is structurally complete and easy to operate. By adjusting the number of return water holes, the inflow rate can be precisely controlled, allowing for timely discharge or recovery of water resources from the tailings dam, achieving the dual goals of production and safety.

[0003] However, in the low temperatures of winter, the spillway's openings are prone to freezing and blockage due to ice accumulation, obstructing the return water channel and hindering smooth drainage. This problem poses a significant challenge to the normal operation of tailings dams, especially in mines in cold northern regions where ice blockage is more common. Once the spillway openings freeze, it not only affects the flow of return water but may also cause the water level in the tailings dam to rise, creating safety hazards.

[0004] To address the problem of freezing and clogging in the spillway's drainage holes, manual de-icing is typically employed. This involves workers manually breaking down the ice layer after it freezes to restore the drainage function. However, this manual method has significant limitations: firstly, manual de-icing is time-consuming and labor-intensive, requiring dedicated personnel for inspection and maintenance, and is difficult to perform in frigid weather; secondly, frequent manual breaking can damage the spillway structure, affecting its lifespan. Therefore, to improve the spillway's anti-freezing and anti-clogging performance in winter, it is necessary to design an automated anti-freezing water system. This would reduce reliance on manual operation, ensure the normal operation of the tailings dam drainage system, and improve the overall safety and reliability of the tailings dam system. Summary of the Invention

[0005] The purpose of this invention is to propose a winter antifreeze and anti-blockage water system for tailings dam spillways, which aims to address the freezing and blockage problem of spillways under low-temperature conditions in winter. This water system can effectively prevent icing in the spillway area, reduce the frequency of manual de-icing operations, ensure the normal operation of the tailings dam drainage system in the cold season, and improve overall safety and operational efficiency.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] The present invention relates to a tailings dam spillway antifreeze and anti-clogging water system, characterized in that it includes a tailings dam spillway, spillway eye, annular water pipe, main water pipe, spray pipe, floating bridge, and support frame.

[0008] The tailings dam spillway is used for drainage and water level regulation of the tailings dam. The spillway eye is located on the periphery of the tailings dam spillway and is used to discharge excess water. The annular water pipe is arranged around the tailings dam spillway to form a closed annular structure. The annular water pipe is fixed to the outer wall of the tailings dam spillway by the support frame and is connected to the main water pipe. The spray pipes are installed at multiple nodes of the annular water pipe and are evenly distributed around the tailings dam spillway.

[0009] The main water pipe is connected to an external water source and serves as the system's water supply channel. The water flow is regulated by a control valve, and water is supplied to the ring water pipe.

[0010] The spray pipes spray water at an angle of less than 30° towards the area surrounding the spillway tower, forming a stable annular water flow field.

[0011] The floating bridge is made of corrosion-resistant, high-strength floating material.

[0012] The support frame is made of antifreeze and corrosion-resistant material.

[0013] Advantages of this utility model:

[0014] (1) The antifreeze and antiblockage water system of the tailings dam spillway tower of this utility model has high antifreeze efficiency and ensures normal drainage: by setting up a ring water system and maintaining the continuous circulation of water flow, the freezing phenomenon of the spillway tower eye in low temperature environment is effectively prevented, thereby ensuring that the spillway tower can still drain normally in winter; this design avoids drainage interruption caused by freezing and blockage of the tower eye and improves the stable operation capability of the tailings dam in cold weather;

[0015] (2) The tailings dam spillway antifreeze and antiblockage water system of this utility model reduces the cost of manual maintenance: Traditional manual de-icing operation is cumbersome and time-consuming. This system greatly reduces the need for manual ice cleaning through automated water circulation and temperature control, reducing the labor intensity and maintenance cost of personnel. At the same time, the system's automatic adjustment function makes operation more convenient, without the need for frequent intervention, and improves operating efficiency.

[0016] (3) The antifreeze and anti-blockage water system of the tailings dam spillway of this utility model extends the service life of the equipment: The design of the ring water channel and the spray pipe can not only prevent freezing, but also avoid damage to the tower structure caused by manual knocking to remove ice, reduce the wear and damage risk of the tower eye and spillway, thereby extending the service life of the equipment and reducing the frequency of equipment replacement and maintenance.

[0020] like Figure 1 , 2 As shown, the anti-freezing and anti-clogging water system for tailings dam spillway towers of this utility model is characterized by comprising a tailings dam spillway tower 1, a spillway tower eye 2, a ring water pipe 3, a main water pipe 4, a spray pipe 5, a floating bridge 6, and a support frame 7.

[0021] The tailings dam spillway 1 is used for drainage and water level regulation of the tailings dam. The spillway eye 2 is located around the tailings dam spillway 1 and is used to discharge excess water. The annular water pipe 3 is arranged around the tailings dam spillway 1 to form a closed annular structure. The annular water pipe 3 is fixed to the outer wall of the tailings dam spillway 1 by the support frame 7 and is connected to the main water pipe 4. The spray pipe 5 is installed on multiple nodes of the annular water pipe 3 and is evenly distributed around the tailings dam spillway 1.

[0022] The main water pipe 4 is connected to an external water source and serves as the water supply channel for the system. The water flow is regulated by a control valve, and water is supplied to the ring water pipe.

[0023] The spray pipe 5 sprays water at an angle of less than 30° towards the area surrounding the spillway tower, forming a stable annular water flow field.

[0024] The floating bridge 6 is made of corrosion-resistant, high-strength floating material.

[0025] The support frame 7 is made of antifreeze and anti-corrosion material.

[0026] Please see Figure 1-2 This utility model proposes a winter anti-freezing and anti-clogging water system for tailings dam spillways, aiming to solve the problem of spillway openings being easily frozen and blocked in low-temperature winter environments, ensuring normal drainage and safe operation of the tailings dam. The system prevents icing around the spillway openings by setting up a ring-shaped water pipe around the spillway and maintaining the circulation of water within the pipe during winter. The specific technical details are as follows:

[0027] Main components: The system mainly consists of tailings dam spillway 1, spillway dam eye 2, ring water pipe 3, main water pipe 4, spray pipe 5, floating bridge 6, support frame 7, etc.

[0028] Tailings dam spillway 1: Used for drainage and water level regulation of the tailings dam. Multiple spillway holes 2 are set around the tower body to control the drainage volume and ensure normal operation under different water level conditions.

[0029] Spillway Eye 2: Located on the outside of the spillway, it is used to discharge excess water, but it is prone to freezing and blockage at low temperatures, which affects the drainage effect.

[0030] Circular water pipe 3: Arranged around the spillway tower to form a closed ring structure, enabling a continuous flow of water around the spillway tower. The circular water pipe is fixed to the outer wall of the spillway tower by a support frame 7 and is connected to the main water pipe 4. The design of this circular water pipe ensures that the water flow can continuously circulate around the tower body during winter operation, preventing freezing around the tower opening due to still water.

[0031] Main water pipe 4: Connects to an external water source, serving as the system's water supply channel. Water flow is regulated by a control valve, supplying water to the loop water pipe. The main water pipe can automatically or manually adjust the water flow rate based on external temperature conditions to maintain stable system operation.

[0032] Sprinkler pipe 5: Installed at multiple nodes of the ring-shaped water pipe, evenly distributed around the spillway. The sprinkler pipe has small-diameter nozzles that can spray water at an angle of less than 30° towards the area surrounding the spillway, forming a stable ring-shaped water flow field and further enhancing the anti-freezing effect. This avoids splashing large water droplets while ensuring the water flow covers the area around the spillway openings at the optimal angle, effectively preventing localized icing.

[0033] Floating Bridge 6: The floating bridge is made of corrosion-resistant, high-strength floating material and can automatically adjust its height according to the rise and fall of the water level, ensuring that the water spray pipes are always at the appropriate height to optimize the spray angle and avoid being affected by water level fluctuations. In addition, the floating bridge design facilitates maintenance personnel to inspect and operate the system.

[0034] Support frame 7: Used to secure the annular water pipe and spray pipe, ensuring the annular water system can be firmly installed on the outer wall of the spillway, enhancing system stability. The support frame is made of antifreeze and corrosion-resistant material, adapting to the complex environment of the tailings dam.

[0035] Working Principle: The antifreeze principle of this invention mainly relies on the continuous flow of water in the annular water system. By setting up an annular water pipe 3 around the tailings dam spillway 1 and maintaining circulating water flow within the annular water pipe 3, a stable surrounding water flow field is formed. Since water is less likely to freeze when in a flowing state, this annular flowing water effectively prevents the water around the spillway dam eye 2 from freezing due to stagnation, thereby ensuring the normal drainage function of the spillway dam eye 2.

[0036] Specifically, the annular water pipe 3, connected to the main water pipe 4, continuously supplies water flow, which is then evenly sprayed around the spillway vent 2 via multiple spray pipes 5, forming a protective flowing water curtain. This water curtain creates a low-temperature buffer zone around the spillway vent 2, preventing cold air from directly impacting the vent. Furthermore, the system can adjust the water flow rate according to temperature conditions; when the outside temperature drops further, the system automatically increases the water flow rate to enhance the antifreeze effect. In extreme low-temperature environments, the heating device at the inlet of the main water pipe 4 preheats the incoming water, ensuring the water temperature remains within a certain range, thereby further enhancing the antifreeze effect.
