[0015] The utility model has the following beneficial effects:

[0016] 1) The water jacket is made of bar material as a whole. Except for the lower end face, there is no weld on the surface in contact with the kiln to avoid cracking of the weld due to heat;

[0017] 2) Redesign the internal flow channel so that the cooling water flows through all areas inside the water jacket to avoid local cooling and improve the cooling effect. BRIEF DESCRIPTION OF THE DRAWINGS
