[0002] The alkali furnace chute operates in the lower part of the furnace at a high temperature of about 1000℃. The molten material can easily produce a large amount of coking on the alkali furnace chute. The coking on the alkali furnace chute will cause blockage and seriously affect the normal operation of the alkali furnace.

[0003] To maintain the normal operation of the sluice, operators need to be on-site to observe the coking condition of the sluice and manually clean the coke by periodically poking it into the sluice with a long steel rod. However, the sluice of the alkali furnace is in a high-temperature state, and due to the unstable negative pressure inside the alkali furnace, the high-temperature molten material may splash out at any time. Even if the operators wear protective clothing, burn accidents still occur frequently during the coking process. Therefore, there is an urgent need for an automatic coking removal system for the alkali furnace sluice to replace manual coking removal, avoid personnel burn accidents caused by high-temperature environments, and ensure the safe and stable operation of the alkali furnace.
