TECHNICAL FIELD

[0001] The utility model relates to a boiler flue field especially relates to a quick installation and dismounting structure of boiler flue. BACKGROUND

[0002] The boiler flue is a pipeline for discharging flue gas generated by combustion in the boiler system, which is usually connected with the furnace of the boiler and is responsible for safely guiding the waste gas generated after fuel combustion outside the boiler. The boiler is a device that generates steam or hot water by burning fuel or using other ways to heat water or other liquids. Its main function is to convert heat energy into mechanical energy or heat energy for industrial, commercial or household use. The boiler is widely used in heating, power generation, industrial production and other fields. It is an important heat conversion and utilization equipment and plays a key role in modern industry and daily life.

[0003] However, most of the traditional boiler flues adopt an integrated structure, which makes it difficult to replace or clean the boiler flue when it is damaged or used for a long time. As a result, the entire flue needs to be replaced when the local damage or corrosion occurs, resulting in high maintenance costs. In addition, it is difficult to clean the inside of the boiler flue, especially the removal of sediments and dirt, which reduces the efficiency of the boiler and increases energy consumption.

Then, the first clamping block and the second clamping block are clamped by rotating the clamping shell, thereby fixing the position between the connecting pipe and the exhaust pipe. Finally, the positioning clamping block is pulled and clamped into the clamping frame to conveniently and quickly complete the installation and fixation. Similarly, the reverse operation can conveniently dismount the boiler flue.
