Description

Material bin Technical Field The invention relates to the technical field of material transfer and storage, in particular to a storage bin. Background In a raw material processing system in the ferrous metallurgy industry, the storage of bulk materials (such as iron ores, coals and the like) is a key link for guaranteeing the continuous production of a blast furnace. At present, the general material warehousing technology is to transfer bulk materials after being transferred and unloaded to a material yard by a belt conveyor. And then, the unloading trolley walks along a track above the bin, and the materials are unloaded into the appointed bin for storage. However, in the actual production process, the following technical problems exist in the warehouse entry mode due to the limitations of process design and equipment structure. Bulk materials, particularly lump mineral materials, are severely impacted and worn on a bin, and when the unloading trolley unloads to a buffering bin, the bulk materials fall vertically under the action of gravity because the vertical fall of the bulk materials is more than 11.5 meters, and directly and violently impact a bin wall lining plate. The long-term large impact forces cause severe wear and damage to the liner. The above problems are to be solved. Disclosure of Invention The invention provides a storage bin, which is used for improving the bearing capacity of the inner wall of the storage bin on the impact and abrasion of materials.
