Description

Technical Field

[0001] This utility model relates to the field of boiler convection section module docking technology, and in particular to a quick-install docking mechanism for a boiler convection section modular platform. Background Technology

[0002] The boiler convection section is an important component of the boiler. Located after the furnace outlet, it consists of convection tube bundles. Through convective heat exchange between flue gas and the working fluid, the working fluid absorbs heat, further increasing its temperature and pressure to meet the heating needs of production and daily life.

[0003] The boiler convection section adopts a modular platform quick-connection mechanism to improve installation efficiency, reduce on-site construction time and workload, ensure connection accuracy, improve installation quality, reduce risks during installation, facilitate later maintenance and component replacement, and improve the overall reliability and maintainability of the boiler.

[0004] In boiler convection section engineering, the modular platform quick-installation docking mechanism is the core component for achieving efficient installation. However, when it is necessary to inspect and replace parts of the boiler convection section, the docking mechanism often uses multiple connection methods to tightly combine various components, making the disassembly process complex and cumbersome, consuming manpower and time, and increasing maintenance costs. Existing technologies have effectively simplified the disassembly process by optimizing the component connection method and using a clamp-on joint structure that is easy to disassemble, allowing maintenance work to proceed quickly and reducing maintenance time and costs. However, in actual use, due to the gaps and interfaces in the docking mechanism, energy loss continues during operation, making it impossible to effectively maintain the boiler's thermal efficiency and hindering the achievement of energy conservation and emission reduction goals.

[0037] Specifically, a temperature base 12 is fixedly connected to the front side of the heat insulation pipe 1, and a thermometer 13 is fixedly connected to the front side of the temperature base 12.

[0038] Reference Figure 3 and Figure 4 A lamp holder 18 is fixedly connected to the top left side of the heat insulation pipe 1. The lamp holder 18 provides support. A warning light 19 is fixedly connected to the top of the lamp holder 18. The warning light 19 serves as a warning.

The multiple bolts 10 are arranged in a ring. The multiple washers 11 are all designed with a smooth shape to avoid damage to the mating sleeve 3. The multiple washers 11 are arranged in a ring to evenly distribute the pressure between the bolts 10 and the mating sleeve 3.

[0039] Specifically, a lamp holder 18 is fixedly connected to the top left side of the heat insulation pipe 1, and a warning light 19 is fixedly connected to the top of the lamp holder 18. The warning light 19 can emit a clear warning signal when the equipment is running, indicating safety and avoiding accidents. Hexagonal grooves 20 are opened on the opposite sides of the multiple bolts 10 on the left and right sides. The hexagonal grooves 20 facilitate the tightening and loosening of the bolts 10 using a hex wrench, improving the convenience of installation and maintenance. The multiple bolts 10 are arranged in a ring. The ring arrangement makes the force more even when the connecting sleeve 3 is connected to the inner tube 4, enhancing the stability and reliability of the connection structure. The multiple gaskets 11 are all designed with a smooth rounded shape. The smooth design of the gaskets 11 can reduce the frictional resistance between the bolts 10 and other components, avoiding damage to the surface of the components during installation and disassembly. The multiple gaskets 11 are arranged in a ring. The ring arrangement of the gaskets 11 can better cooperate with the bolts 10, evenly distribute the pressure, prevent stress concentration at the component connection, and improve the connection effect.

[0040] Working principle: Align the positioning piece 6 with the positioning groove 7 on the right side of the furnace tube 9 to quickly achieve initial positioning, reduce installation and calibration time, ensure the accuracy of the docking position, and reduce the difficulty of subsequent adjustments. By tightening the multiple bolts 10 between adjacent parts of the outer wall of the docking sleeve 3, the docking sleeve 3 is firmly fixed to the outer wall of the inner tube 4, realizing a reliable connection between the convection section and the furnace tube 9, ensuring a tight and stable connection, so that the entire structure can withstand corresponding pressure and vibration during operation. The sealing sleeves 5 at the left and right ends of the inner wall of the inner tube 4 seal the gaps during docking to prevent the leakage of flue gas or working fluid, improve the overall sealing performance, and avoid heat loss and safety hazards caused by leakage. The flue gas and working fluid generated by the furnace 8 enter the inner tube 4. The inner tube 4 serves as a convection site, allowing the working fluid and flue gas to exchange heat through convection, achieving effective heat transfer, thereby meeting the heat demand in production and daily life. The outermost heat insulation pipe 1 locks the heat inside the pipe, reducing heat loss, improving energy utilization efficiency, reducing energy consumption, and contributing to energy conservation and emission reduction.

[0041] Furthermore, the heat insulation pipe 1 is placed on top of the buffer pad 201. The buffer pad 201 absorbs the impact force generated during placement, preventing damage to the heat insulation pipe 1. An external traction device can be connected through the traction ring 203 to pull the entire moving mechanism 2. With the action of the casters 205, the moving mechanism 2 can move flexibly, making it convenient to transport the heat insulation pipe 1 to the designated position. When it moves close to the installation position, the handles 206 on the front and rear sides of the plate 202 can be used to make minor adjustments to the position of the moving mechanism 2 to ensure that the heat insulation pipe 1 is in place. The bracket 204 raises the plate 202 to provide installation space for the casters 205, so that the moving mechanism 2 remains stable during movement, realizing convenient movement and positioning of the convection section, and providing convenience for the installation and commissioning of the boiler convection section modular platform.
