Description

Large-block material crushing and cleaning device applicable to belt conveyor for iron making [ Field of technology ] The utility model belongs to the technical field of mine material transportation, and particularly relates to a bulk material crushing and cleaning device applicable to a belt conveyor for iron making. [ Background Art ] In the pre-iron sintering step of steel production, the quality of the sintered cloth has a critical influence on the quality of the final steel product. At present, the material distribution method of the swinging belt widening belt conveyor and the eleven rollers is widely applied to iron making and sintering, and the four-belt conveyor is used as the final process equipment of a material distribution system after uniformly mixing and pelletizing ingredients, and the working condition of the final process equipment is directly related to the quality of sintered material distribution. However, in actual production, large materials often appear on a four-belt conveyor due to the complexity of links such as raw material purchase, storage, transportation and the like. The traditional processing mode mainly comprises two modes of manual inspection and simple mechanical device use. Manual inspection relies on experience and responsibility of operators, is low in efficiency, is difficult to ensure that all massive materials are found and processed in time, cannot meet the requirement of efficient production in the pre-iron sintering production environment, and is easy to cause production interruption and unstable quality. Simple mechanical devices such as grids and the like can block part of massive materials from entering a distribution system, but cannot be broken and removed, and accumulated materials still can influence normal production. [ utility model ] The utility model aims to provide a large-block material crushing and cleaning device suitable for an ironmaking belt conveyor, which aims to solve the problem that the conventional belt conveyor cannot crush and clean large-block materials and influences normal production.
