[0004] In the existing technology, CN218846844U adopts a structure that can hold the steel wire rope in place during use, effectively avoiding the problem of the steel wire rope being dislocated, and uses a multi-layer plate for sealing, effectively preventing the leakage of high-temperature gas and the infusion of cold air. It is stable and reliable to use, and has a useable value in the field of cement rotary kiln application technology. However, although the fish scales can be fixed by tying the steel wire rope during use, the steel wire rope is in a high temperature state for a long time, causing the material of the steel wire rope to change, and it is easy to break, fatigue and other problems during use. When the steel wire rope breaks, it will cause a safety accident and reduce the sealing performance of the rotary kiln. Therefore, a rotary kiln head sealing structure is needed to solve the above problems. Utility Model Content
