Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, an opening is provided in the furnace body 1, and the opening is a smoke outlet of the furnace body 1, and the smoke outlet is connected to a flue 2, and smoke generated in the furnace body 1 is discharged out of the furnace body 1 through the flue 2. The flue 2 is of a square structure, can be better matched with the smoke outlet of the furnace body 1, and ensures the maximum emission of smoke. The bottom of the flue 2 is connected with the copper water jacket 3, the copper water jacket 3 and the flue 2 are of an integrated structure, the copper water jacket 3 drives the flue 2 to be integrally inserted into a smoke outlet of the furnace body 1, and the situation that the connection of the connection part is not tight enough and smoke is discharged from the bottom of the flue to influence the working environment is avoided. Be equipped with inside lining 4 in flue 2, inside lining 4 adopts 380mm refractory material, and is provided with the steel construction outside inside lining 4, and the steel construction supports as the outside of inside lining 4, and inside lining 4 adopts refractory material, can effectively prolong flue 2's life. The top of flue 2 is equipped with top cap 5, and this top cap 5 is the water-cooling hunch lid, and the inside lining a6 of water-cooling hunch lid adopts 200mm refractory material, can cool down top cap 5, when improving the security, adopts refractory material can effectively reduce the sediment rate that falls of top cap 5, keeps work normal clear, improves production efficiency.
