[0031] Layout of the welding studs 3 and the connecting welding studs 5: The design of welding at equal intervals on the outer surface of the electrode heater 1 ensures that the heat preservation sleeve layer 2 evenly covers the electrode heater 1, making the heat distribution more balanced, and at the same time providing a firm support point for the heat preservation sleeve layer 2.

[0032] Function of the internal thread sleeve 4: The threaded connection between the internal thread sleeve 4 and the welding stud 3 not only facilitates the installation of the heat preservation sleeve layer 2, but also strengthens the connection strength and sealing performance between the heat preservation sleeve layer 2 and the electrode heater 1 through welding and sealing after installation.

The connecting welding nails 5 are located between every two thermal insulation sleeve layers 2. Thread-fix the outer end of the welding nail 3 with the installed thermal insulation sleeve layer 2 through the internal thread sleeve 4.

At the open end of the internal thread sleeve 4, the cross-section is relatively large, wrap the outer end of the through-hole of the corresponding thermal insulation sleeve layer 2, and perform positioning, located between two thermal insulation sleeve layers 2. The upper end of the connecting welding nail 5 is engaged with the movable cylinder 7 in the rotating cylinder 8 through the movable sleeve 6, and rotate the rotating cylinder 8 through the movable sleeve 6 to drive the hook grooves 10 at both ends of the rotating arc plate 9 to be engaged with the corresponding internal thread sleeve 4. When they are engaged with each other, wrap the outer thread sleeve 11 outside the internal thread sleeve 4 and position the hook grooves 10.
