[0002] A fuming furnace is a device that blows a mixture of air and pulverized coal into liquid slag, so that some valuable metals in the slag are volatilized in the form of metals, oxides or sulfides. The fuming furnace was originally a device for treating lead blast furnace slag. In non-ferrous metallurgy enterprises, various slags (especially lead-zinc slag and tin slag) are widely treated by fuming furnaces. The ignition temperature of the pulverized coal and air mixture is 350-500°C. Its two sides, both ends, furnace bottom and furnace top are all assembled by water jackets. Its structure mainly includes a tuyere device, a molten slag injection device, a cold charge addition device, a slag discharging port, a slag discharging and plugging device, a water jacket flue, etc. In the production process of pyrometallurgical zinc smelting, the slag discharging process is an intermittent operation. At the end of each cycle, the high-temperature molten slag must be discharged from the furnace to avoid affecting normal production. Traditional discharge devices rely on manual use of simple slag rods for plugging and discharging.

The input end of the water injection docking pipe 11 extends into the plug 10. A water delivery pipe 12 is connected to the water injection docking pipe 11; A water outlet pipe 13 is also connected to the plug 10.
[0025] In this embodiment, external circulating water can be injected into the plug 10 through the water delivery pipe 12 and the water injection docking pipe 11 and discharged through the water outlet pipe 13, so as to reduce the temperature of the plug 10 and improve the service life of the plug 10.
