Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of limestone silo unloading, in particular to a limestone silo unloading and unblocking device. Background Art
[0002] Limestone is a sedimentary rock primarily composed of calcium carbonate, typically appearing gray, white, or pale yellow. A limestone silo typically refers to the area where limestone is stored. As an important industrial raw material, limestone is widely used in cement production, steel manufacturing, chemical industry, environmental protection, and other fields. During the storage and transportation of limestone, material blockages are common, especially during the unloading process of limestone silos. This blockage not only affects production efficiency but can also cause equipment damage and safety hazards. Therefore, a device for unloading limestone silos to relieve blockage is needed.
[0003] During use, traditional limestone silo unloading and unblocking devices usually store limestone directly in the limestone silo through the feed port, which usually does not have a crushing function. The lack of a crushing function means that when the limestone material accumulates due to large particles or agglomerates, these large lumps cannot be effectively broken, causing the discharge channel to be easily blocked, affecting the normal flow of materials. Moreover, traditional limestone silos usually do not have a stirring function, which affects the material discharge speed, resulting in a decrease in overall discharge efficiency and reduced production efficiency.
