AI Technical Summary
The existing protective sleeve is not easy to disassemble, which affects maintenance efficiency. The branch sleeve and the main sleeve are integrated into one structure, which makes the installation and disassembly of thermocouples cumbersome, and the thermocouple probe end is easily scratched.
The main sleeve is fixedly mounted with a first flange and bolted to the roasting furnace. The branch sleeves are set at an angle. The main sleeve is equipped with a partition plate and a connecting pipe. The branch sleeves are detachably connected to the main sleeve through the second and third flanges. The inner diameter of the branch sleeves is smaller than that of the main sleeves.
It improves the ease of maintenance of the protective sleeve, reduces the risk of thermocouple scratches, lowers installation resistance, and extends service life.
