[0002] The fuming furnace is a device that blows a mixture of air and pulverized coal into the liquid slag to volatilize certain valuable metals in the slag in the form of metals, oxides or sulfides. During smelting in an electric furnace, a large amount of rich slag is produced, containing about 10% tin, which needs to be recovered by smelting in the fuming furnace. After the slag is smelted in the fuming furnace, the smelted waste slag will remain inside the fuming furnace, and the waste slag will easily condense if it stays in the fuming furnace for a long time, which is inconvenient to clean the waste slag manually. In view of this, this application is specially proposed. Utility Model Content

[0025] The slag discharge device includes a motor 4, a limit unblocking ball 5 and a through hole 6. The motor 4 is arranged on the recovery device. The limit unblocking ball 5 is rotatably arranged inside the slag discharge pipe. The through hole 6 is penetrated and opened on the limit unblocking ball 5. The limit unblocking ball 5 is connected to the output shaft of the motor 4, and the surface of the limit unblocking ball 5 is smooth.

[0026] By adopting the above technical scheme, the slag is poured into the interior of the fuming furnace body 1 through the feeding device, and then the slag is smelted inside the fuming furnace body 1. During the smelting process, the hot gas generated will be discharged through the air outlet pipe 2 for recovery, so that the waste heat can be recycled, and the setting of the filter 7 can filter the flue gas to prevent the exhaust pipe 2 from being blocked by excessive impurities in the flue gas. It should be noted that the lower side of the fuming furnace body 1 is conical, so the waste slag will gather in the direction of the slag discharge pipe 3.

[0032] By adopting the above technical solution, when feeding is needed, the cover 11 is opened, and then the slag is poured into the pouring chute. The baffle 12 will rotate downward under the gravity of the slag, and the elastic member 13 will be deformed. When the slag falls, the baffle 12 will rotate in the opposite direction and reset under the resetting action of the elastic member 13. At this time, the baffle 12 will block the smoke of the fumigation furnace body 1, and then the entrance of the guide chute 10 can be closed by the cover 11.
