Description

Technical Field

[0001] The utility model relates to the technical field of sintering machine related equipment, in particular to a structure of a rotary material loosener. Background Art

[0002] The material loosener is a key device used to improve the air permeability of the material layer during the sintering process. Its existence can significantly improve the operation efficiency of the sintering machine, promote the increase of the output of sintered ore, and help reduce energy consumption. However, due to the sundries that may be carried in the raw materials and the relatively high moisture content of the materials themselves, problems such as sticking materials and hanging sundries often occur during the use of the material loosener. These problems often lead to the appearance of hook-shaped phenomena on the sintered material surface during the feeding process. Therefore, regular cleaning of the material loosener has become a necessary task in the production process. In the conventional cleaning operation, it is usually necessary to stop the cylindrical feeding, expose the main body of the material loosening rod, and then the workers use a U-shaped steel bar to manually clean it. However, this cleaning method not only causes a short-term shutdown of the production line, but also may cause the material on the surface to fall off during the cleaning process, both of which will have an adverse impact on the sintering effect of the surrounding materials.

[0003] Therefore, solving the problems of material sticking of the material loosener and the series of production problems caused by shutdown cleaning is a necessary way for the future development of sintering process equipment. Content of the Utility Model
