[0001] The utility model relates to the technical field of cleaning technology for sticky materials in cylindrical silos, in particular to a rotary cutting type cleaning device for cleaning sticky materials on the wall of a cylindrical silo. Background Art

[0002] Large cylindrical silos are essential material buffer facilities in the metallurgical and coal industries. They serve as storage equipment in mechanized bulk material handling systems, primarily serving as intermediate storage, system buffers, and load balancing. During the production process, materials entering the silo typically contain a certain amount of moisture. Some materials may also contain adhesives, which can cause the material to adhere to the silo walls, reducing its fluidity and, in severe cases, causing blockage.

[0003] Cleaning large silos has always been a challenge in the production process. Due to the silo's structure, large cleaning equipment cannot easily enter the silo. Silo cleaning is still mainly done manually. Workers enter the silo through the material discharge port on the top and use sledgehammers or jackhammers to clean the material, which is inefficient. Poor air circulation within the silo and the falling of material stuck to the silo wall pose a serious threat to the safety of the cleaning workers. We have proposed a device for cleaning material stuck to the silo wall that effectively solves this problem and ensures the safe and efficient operation of the silo system. Utility Model Content
