After the combustion furnace has been running for a long time, the slag accumulated and compacted in slag discharge channel 3 gradually increases, thereby affecting normal slag discharge. When the slag discharge of slag discharge channel 3 is affected, the slag discharge is firstly discharged through hydraulic telescopic rod 6. The reciprocating extension and retraction of the rod 6 drives the alloy crushing head 9 to do reciprocating linear motion. The alloy crushing head 9 has the advantages of high strength and high temperature resistance, and can effectively and quickly crush the compacted slag, and quickly clear the slag discharge channel 3 by means of reciprocating collision. Then, the rotating cylinder 5 drives the conical head 7 and the spiral cutting blade 10 thereon to rotate, and then cooperates with the linear motion of the hydraulic telescopic rod 6 to scrape off the slag attached to or compacted on the inner wall of the slag discharge channel 3, thereby further clearing the slag discharge channel 3, so that the slag discharge flow of the slag discharge channel is not affected, and the slag discharge can be cleared and discharged at any time after being blocked, which solves the slag discharge problem caused by long-term operation of the existing combustion furnace.
