Description

Technical Field

[0001] This utility model relates to the field of alloy pipes, specifically an alloy pipe structure for a waste incineration power plant. Background Technology

[0002] Waste-to-energy incineration plants are modern power generation systems that utilize the heat released from the incineration of municipal solid waste to generate electricity. By burning waste at high temperatures, the organic matter in the waste is converted into high-temperature steam, which drives a turbine to rotate and a generator to produce electricity. This process not only treats waste and reduces its pollution to the environment but also achieves energy recovery and utilization, providing greater energy security for the local area. The generator, driven by a steam turbine or gas turbine, supplies renewable energy to urban or industrial areas. The alloy piping structure of waste-to-energy incineration plants mainly refers to the pipes and their connections made of alloy materials used in the system. This pipe structure is crucial in waste-to-energy incineration plants. Alloy pipelines play a crucial role in waste-to-energy plants. They are typically made of alloy materials with good high-temperature resistance, low-temperature resistance, and corrosion resistance, allowing them to maintain good mechanical properties and stability even under high-temperature, high-pressure, and corrosive environments. In waste-to-energy plants, due to the high-temperature flue gas and corrosive gases generated by combustion, the use of alloy pipelines ensures the safe and stable operation of the system. The alloy pipeline structure of waste-to-energy plants refers to the pipelines made of alloy materials and their connection methods, which play a vital role in waste-to-energy plants. Through reasonable material selection, structural design, and connection technology, the safe and stable operation of the pipeline system can be ensured, providing strong support for the operation of waste-to-energy plants.

[0003] According to Chinese Patent Publication No. CN114382954A, an aluminum alloy pipe for high-pressure environments includes an outer pipe, radial supports, an axial support plate, and an inner pipe. The outer pipe is sleeved over the inner pipe, forming a connecting cavity between them. One end of the radial supports is fixed radially to the outer wall of the inner pipe, and multiple radial supports are provided, with the other end of each fixed to the axial support plate, which is fixed to the outer wall of the outer pipe. The proposed aluminum alloy pipe for high-pressure environments has a simple structure. The radial supports and axial support plate, positioned between the outer and inner pipes, increase the strength of the aluminum alloy pipe. Furthermore, by changing the pressure within the connecting cavity, the stress on the outer pipe is reduced, increasing its service life.

[0004] In the above scheme, a connecting cavity is formed between the outer and inner tubes; one end of the radial support is fixed radially to the outer wall of the inner tube, and multiple radial supports are provided, with the other end of each radial support fixed to the axial support plate. This results in the following disadvantages: the installation and subsequent maintenance of existing power plant alloy pipes require disassembly of the joints. The existing alloy pipe joints are fixed by threaded connections, and installers need to spend a lot of time disassembling the joints during later repairs. This operation is cumbersome, time-consuming, and labor-intensive, reducing work efficiency. Moreover, the outer surface of the alloy pipe is easily dented under pressure, reducing its practicality. A lot of time is required to repair it, reducing the overall strength of the pipe body, which is not conducive to long-term use and increases costs. Utility Model Content

[0005] The purpose of this utility model is to provide an alloy pipe structure for waste incineration power plants, in order to solve the problem that the joints of existing alloy pipes need to be disassembled during the installation and subsequent maintenance of the alloy pipes in the power plant. The joints are fixed by threaded connections, and the installers need to spend a lot of time disassembling the joints during the later maintenance process.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an alloy pipe structure for a waste incineration power plant, comprising a first pipe, a first circular groove formed on the first pipe, a connecting pipe fixedly connected to one side of the first pipe, a telescopic component for easy installation and disassembly provided on the connecting pipe, an outer pipe body provided on one side of the connecting pipe, and a protective component for preventing dents provided on the outer pipe body.

[0007] Preferably, the telescopic component includes a first limiting ring, which is fixedly connected to a first pipe. A second pipe is provided on one side of the first pipe. A spring is installed on the second pipe. A fixing ring is fixedly connected to one end of the spring. A sleeve is fixedly connected to the outer wall of the fixing ring. A second limiting ring is fixedly connected to the outer wall of the second pipe. A groove is formed on the second pipe. A ball is installed on the groove. A connecting groove is formed on the connecting pipe.

[0008] Preferably, the protective component includes a restorative inner core, which is fixedly connected to the outer tube. An inner tube is disposed inside the outer tube, and the outer tube is sleeved on the outside of the inner tube. A plurality of elastic columns are installed around the outer wall of the reinforcing tube, and a reinforcing tube is installed outside the elastic columns. The elastic columns are all disposed between the inner tube and the reinforcing tube, and the restorative inner core is disposed between the reinforcing tube and the outer tube.

[0009] Preferably, the outer surface of the outer tube is provided with several anti-slip textures, and the connecting tube is provided with threaded grooves.

[0010] Preferably, the inner wall of the inner tube is coated with an anti-rust coating, and the second pipe has a second circular groove.

[0011] Preferably, the outer wall of the outer tube is coated with a wear-resistant coating, and a connecting ring is installed on the second pipe.

[0012] Compared with existing technologies, the alloy pipe structure for a waste-to-energy plant that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] I. In use, the operator first moves the sleeve on the outer wall of the second pipe downwards. Then, the spring connected to the fixing ring on the inner wall of the second pipe moves downwards. At this time, the first pipe is inserted into the second pipe. When the first limiting ring on the first pipe reaches the groove and the movement stops, the sleeve is then released. At this time, the inner sleeve of the second pipe moves upwards under the action of the spring until it reaches the groove and stops moving. Then, the ball in the groove is squeezed inwards by the sleeve and successfully locks into the first limiting ring and is fixed in the groove. This allows for convenient and quick installation and disassembly of the alloy pipe for maintenance. Convenient and easy to use, this structure improves work efficiency, is quick and convenient, saves time, and greatly reduces the labor intensity of maintenance workers. When the outer wall of the outer tube is squeezed, the elastic column is squeezed inward by the force. When the external pressure is gone, the elastic column recovers and resists pressure outward, realizing the anti-compression effect of the alloy pipe, enhancing the practicality and flexibility of the alloy pipe. Then, under the action of the recovering inner core, the anti-compression effect of the outer wall of the outer tube is increased, improving the overall strength of the alloy pipe, improving the stability in use, and improving the quality of the alloy pipe.

[0021] like Figures 1-5 As shown, an alloy pipe structure for a waste incineration power plant includes a first pipe 1 with a first circular groove. A connecting pipe 2 is fixedly connected to one side of the first pipe 1. The connecting pipe 2 is equipped with a telescopic assembly for easy installation and disassembly. An outer pipe body 10 is provided on one side of the connecting pipe 2, and a protective assembly to prevent denting is provided on the outer pipe body 10. The telescopic assembly includes a first limiting ring 3, which is fixedly connected to the first pipe 1. A second pipe 4 is provided on one side of the first pipe 1, and a spring 5 is installed on the second pipe 4. A fixing ring 8 is fixedly connected to one end of the spring 5, and a pipe sleeve 7 is fixedly connected to the outer wall of the fixing ring 8. A second limiting ring 6 is fixedly connected to the outer wall of the second pipe 4. A groove 9 is provided on the second pipe 4, and a ball 16 is installed in the groove 9. The connecting pipe 2 has a connecting groove 14. The protective component includes a restoring inner core 11, which is fixedly connected to the outer pipe body 10. An inner pipe body 15 is provided inside the outer pipe body 10, and the outer pipe body 10 is sleeved on the outside of the inner pipe body 15. Several elastic columns 13 are installed around the outer wall of the reinforcing pipe 12. The reinforcing pipe 12 is installed outside the elastic columns 13. The elastic columns 13 are all located between the inner pipe body 15 and the reinforcing pipe 12. The restoring inner core 11 is located between the reinforcing pipe 12 and the outer pipe body 10. Several anti-slip textures are provided on the outer surface of the outer pipe body 10. The connecting pipe 2 has a threaded groove. The inner wall of the inner pipe body 15 is coated with an anti-rust coating. The second pipe 4 has a second circular groove. The outer wall of the outer pipe body 10 is coated with a wear-resistant coating. A connecting ring is installed on the second pipe 4.

[0022] In use, the operator first moves the sleeve 7 fitted on the outer wall of the second pipe 4 downwards. Then, the spring 5 connected to the fixing ring 8 on the inner wall of the second pipe 4 moves downwards. At this time, the first pipe 1 is inserted into the interior of the second pipe 4. When the first limiting ring 3 on the first pipe 1 reaches the groove 9 and the movement stops, the sleeve 7 is then released. At this time, the sleeve 7 inside the second pipe 4 moves upwards under the action of the spring 5 and stops moving when it reaches the groove 9. Then, the ball 16 in the groove 9 is squeezed inwards by the sleeve 7 and then successfully locked onto the first limiting ring 3 and fixed in the groove, realizing convenient and quick installation and disassembly of the alloy. The pipeline is easy to maintain. This structure is easy to use, improves work efficiency, is convenient and quick, saves time, and greatly reduces the labor intensity of maintenance workers. When the outer wall of the outer tube 10 is squeezed, the elastic column 13 is squeezed inward by the force. When the external squeezing force is gone, the elastic column 13 recovers and resists the pressure outward, realizing the anti-compression effect of the alloy pipeline, enhancing the practicality and flexibility of the alloy pipeline. Then, under the action of the recovery inner core 11, the anti-compression effect of the outer wall of the outer tube 10 is increased, improving the overall strength of the alloy pipeline, improving the stability in use, and improving the quality of the alloy pipeline.
