Description

Technical Field

[0001] The utility model belongs to the technical field of tailings transportation, and particularly relates to a rapid leakage stoppage device for a long-distance transportation pipeline of a tailings reservoir. Background Art

[0002] In recent years, due to the rise of the mining industry, the number of mine openings has been increasing day by day. Tailings are one of the necessary and important products in the ore dressing operation. Tailings refer to the part with a low content of useful target components in the products of the ore dressing operation and cannot be used in production. The tailings generated in the ore dressing process will cause great harm to the environment. Therefore, it is necessary to centrally recover and discharge them into a fixed tailings reservoir. As a major hazard source, the operation of the tailings reservoir is not only related to the economic benefits and production safety of the enterprise, but also threatens the lives and property of the residents in the reservoir area and the surrounding environment. The tailings reservoir transportation system is of great significance to the overall safety of the tailings reservoir. As is well known, tailings slurry is a kind of waste generated in mines and needs to be transported back to the tailings reservoir for stacking through a transportation pipeline. Since the tailings slurry contains solid particles and liquid components, high pressure, high speed and long-distance transportation are often required during the transportation process. The transportation pipeline is directly related to the safety and economy of the entire tailings slurry treatment process. The long-distance transportation pipeline of the tailings reservoir is prone to leakage during operation. This not only requires safe and timely plugging and leakage stoppage for repair, but also ensures that the tailings sand is not discharged from the transportation system. If the leakage cannot be stopped in time, once leakage occurs, it will cause great harm to the environment and surrounding residents, and even cause catastrophic consequences. This puts forward higher requirements for the timely and efficient plugging and leakage stoppage of the leakage of the long-distance transportation pipeline of the tailings reservoir. Although the project volume of the rapid leakage stoppage device for the wear-resistant pipeline of the tailings is very small, its importance is very great and must be highly emphasized. Therefore, solving the problem of rapid leakage stoppage of the long-distance pipeline transportation of tailings has become an important task to ensure safe production. Summary of the Invention

[0023] Embodiment

[0024] As Figure 1 and 2 shown, this embodiment discloses a rapid leak stoppage device for a long-distance conveying pipeline of a tailings pond, including an extension pipe 1 provided on the side wall of the pipeline 0 and communicating with the inner cavity of the pipeline 0. The extension end of the extension pipe 1 is hermetically covered with a cover plate 2. An airbag 3 is further provided between the cover plate 2 and the extension end of the extension pipe 1. The airbag 3 is sealed between the cover plate 2 and the extension pipe 1 respectively. A pressure regulating component 4 is also provided on the cover plate 2;

[0025] Its function is as follows: When in use, the quick leak stoppage device for the long-distance conveying pipeline of the tailings pond is installed at a position adjacent to the upstream of the easy leak point of pipeline 0. When pipeline 0 leaks, the space between the cover plate 2 and the airbag 3 is pressurized and inflated through the pressure regulating component 4, so that the airbag 3 expands into the inner cavity of pipeline 0 until the top of the airbag 3 completely adheres to the inner wall of pipeline 0 to achieve quick leak stoppage; after the leak point of pipeline 0 is repaired, the space between the cover plate 2 and the airbag 3 is decompressed and exhausted through the pressure regulating component 4, and the top of the airbag 3 retracts from the inner cavity of pipeline 0 into the extension pipe 1; the whole device is easy to implement, and the operation process is simple and fast, greatly improving the leak stoppage work efficiency and reducing the labor intensity of the operators at the same time.

[0026] Among them, multiple quick leak stoppage devices for the long-distance conveying pipeline of the tailings pond disclosed in this embodiment can be installed on pipeline 0 according to the actual working conditions. According to the position of the leak point when pipeline 0 leaks, the leak stoppage device at the adjacent upstream position is pressurized and inflated in time for leak stoppage; the overall high flexibility and high leak stoppage efficiency enable it to meet the quick leak stoppage requirements of long-distance pipelines in complex terrains, and improve the stability and reliability of the tailings conveying system.

[0027] Among them, the extension pipe 1 can select a short tee branch pipe facing the bottom of pipeline 0, and the axis of the extension pipe 1 is perpendicular to the axis of pipeline 0. In actual working conditions, certain sediment will be generated in pipeline 0. Due to the existence of the sediment, the abrasion amount at the bottom of pipeline 0 is relatively small. The device is installed at the bottom of the pipeline and is not likely to damage the device.

[0028] Among them, the airbag 3 selects airbags of appropriate sizes and materials according to the different pipeline diameters and plugging positions. The airbag 3 can be made of materials with high strength, corrosion resistance and wear resistance to ensure that the airbag has sufficient strength, sealing performance and wear resistance. The airbag 3 disclosed in this embodiment can be selected as a rubber wear-resistant high-pressure airbag.

[0029] The pressure regulating component 4 includes an inflation valve 4-1 and an exhaust valve 4-2 provided on the cover plate 2, and the inflation valve 4-1 is also provided with a pressure gauge 4-3;

[0030] Its function is as follows: In order to avoid damage to the airbag 3 caused by too fast inflation, the inflation valve 4-1 is used to gradually pressurize and inflate and control the inflation speed, and at the same time, the pressure change of the pipeline is observed at any time through the pressure gauge 4-3 to ensure the safety of the pipeline. After the inflation reaches the set pressure, the inflation valve 4-1 is closed when the top of the airbag 3 completely adheres to the inner wall of pipeline 0; after the leak stoppage is completed, the air is exhausted through the exhaust valve 4-2 until the exhaust valve 4-2 is closed after the pressure gauge 4-3 detects sufficient exhaust. The whole device is made of high-strength stainless steel material to ensure that it is not easily damaged, corroded or deformed during long-term use.

[0031] The cover plate 2 disclosed in this embodiment is a flange blind plate. A connecting platform matching the port structure of the flange blind plate is provided at the extended end of the extension pipe 1. It also includes a plurality of fixed shafts 5 for sealing and fixedly connecting the port of the flange blind plate and the extended end of the extension pipe 1. The fixed shaft 5 can be selected as a bolt to achieve the sealing and fixation between the cover plate 2 and the extension pipe 1; to prevent shaking during the inflation operation, with precise design, it can ensure the stability and non-deviation during the pipeline leak stoppage and inflation operation, effectively preventing the leakage problem caused by the displacement of this device and ensuring safety and reliability; at the same time, to ensure the sealing effect, a sealing ring can also be provided between the port of the flange blind plate and the extended end of the extension pipe 1.

[0032] The preferred embodiments of the present disclosure have been described in detail above with reference to the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0033] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combination methods.
