[0001] The utility model belongs to the technical field of preheater cyclones, and in particular relates to a connection structure for hanging pieces of an inner cylinder of a preheater cyclone. Background Art

[0002] The cyclone preheater is the core equipment of the new dry cement production technology. It uses a suspended preheating method to complete the preheating and partial decomposition of raw materials, thereby shortening the length of the rotary kiln. At the same time, the raw materials are fully mixed with the hot air flow in the kiln, improving the heat exchange efficiency, thereby achieving the purpose of improving the production efficiency of the entire kiln system and reducing the heat consumption of clinker burning. In the cyclone of the preheater, in order to reduce the wear of the cyclone, a hanging plate structure is generally installed on the inner wall of the cyclone so that the hanging plate contacts the cement raw materials instead of the cyclone, reducing the wear of the cyclone.

[0003] When the hanging plate is used, if it is damaged after long-term use, it needs to be disassembled and replaced. However, most existing hanging plates are fixed with bolts, which is inconvenient to disassemble and install, making it inconvenient to replace the hanging plate, reducing the replacement efficiency of the hanging plate. In addition, when the hanging plate is installed, if the gap between adjacent hanging plates is large, it will affect the use of the hanging plate. If the gap between adjacent hanging plates is small, when the hanging plate expands due to heat, it will squeeze the adjacent hanging plates, thereby affecting the use quality of the hanging plate.
