Description

Storehouse body inner wall clearance mechanism

Technical Field

The utility model belongs to the technical field of the material is carried, concretely relates to bin body inner wall clearance mechanism.

Background

After materials and the like of the existing cement kiln are taken out from a storage bin, the materials and the like enter a buffer bin, a discharge bin, a belt conveyor and other mechanisms through pipelines to be conveyed to required equipment. After the blanking pipeline and the blanking bin work for a period of time, materials can be stacked on the blanking port and the buffer bin above the blanking port. And some raw materials are greatly influenced by climate, such as sandstone, iron ore, coal gangue, clay, desulfurized gypsum and the like. In rainy or damp weather, the materials have high moisture and high viscosity, and are often accumulated and hardened on the wall of the silo, so that the phenomena of skinning, arching and blocking occur. When the current cement silo has a material blocking phenomenon, a field worker usually uses a tool to smash and dredge the materials, or an air cannon is arranged on the outer side of the silo wall. The labor intensity of manual material tamping is high, the efficiency is low, and the blockage removing effect of the air cannon is poor.

Patent CN216944504U discloses a rotatory broken device that encircles of conical feed bin of cement, including sectional type feed bin subassembly, rotating assembly and scraper blade subassembly, the sectional type feed bin subassembly connects feed bin, feed bin one, gyration storehouse and feed bin two including connecing feed bin, feed bin one, gyration storehouse and feed bin two to communicate in proper order, and the scraper blade unit mount is inside the gyration storehouse, and the outer wall and the rotating assembly in gyration storehouse, rotating assembly drive gyration storehouse are rotated. Relative motion is generated between the rotary bin and the first bin and between the rotary bin and the second bin, and then a scraper on the inner wall is utilized to break the arch and clear the blockage; the upper and lower groups of scrapers rotate continuously to break the arch and clear the blockage.

However, this rotary scraping method can only be used for circular or conical feeders. The non-conical buffer bin and other square or polygonal bin bodies connected above the discharging bin cannot be cleaned by applying the structure.
