Description

Technical Field

[0001] The utility model relates to the technical field of raw material and fuel transportation in the metallurgical industry, in particular to a material chute with an anti-blocking and anti-adhesion device. Background Art

[0002] In blast furnace production, material transportation of the feeding system is an important component. The raw materials and fuels required in the blast furnace smelting process are processed by the vibrating screen equipment of the feeding system. The materials on the screen are transported to the blast furnace via a belt, and the materials under the screen fall onto the recovery belt through a chute and are transported to the recycling station.

[0003] Screened material, characterized by small particle size and high powder content, easily sticks to the chute when it has a high moisture content. This is especially true for lump minerals, which are mostly stored outdoors and have a higher moisture content during the rainy season. This can cause them to stick together or form a sludge, further increasing the risk of chute sticking during the screening process. This requires prompt cleaning, increasing labor intensity for workers. If not discovered in time, the chute can become clogged, impacting normal production. A device to prevent chute sticking, maintain chute flow, and ensure normal production is a pressing issue for those skilled in the art. Utility Model Content
