Description

Ash removal device

Technical Field

The utility model relates to a furnace body deashing field specifically is an ash removal device.

Background

The rotary hearth furnace reduction technology is that carbon-containing pellets which are prepared by batching, mixing, pelletizing and drying metallurgical dust, dedusting ash, steelmaking sludge and the like in a factory are added into an annular hearth and a rotary hearth furnace at the bottom of the rotary hearth furnace, and iron in the pellets is reduced by carbon at the hearth temperature of about 1350 ℃. In the process of pellet reduction, the atmosphere in the furnace is full of various complex components, so that furnace dust adheres to the furnace wall and the positions near observation holes of a full-field temperature measurement probe and a high-temperature industrial television probe for observing the heated pellets in the furnace. The furnace dust is fast bonded in the furnace, and blocks the observation path and the observation hole, so that the temperature measurement and monitoring equipment cannot work normally.

At present, workers stretch into an iron rod at random to push and sweep forcibly, so that the working efficiency is low, the labor intensity is high, the cleaning effect is poor, and the visual operation in the rotary hearth furnace is greatly influenced.
