Figure 1 As shown: a blast furnace discharge system, including a blast furnace forebed, a gas collecting hood 3, a gas collecting flue, a dust collector 1, a frame 12, a track 14, a tractor 6 and a controller 5, wherein the blast furnace forebed is provided with an antimony matte port 11 and a precious antimony port 10.

[0017] The gas collecting hood is arranged above the front bed of the blast furnace, and is connected to the dust collector through the gas collecting flue 2. A flue gas concentration sensor 4 is arranged in the gas collecting hood; a plurality of antimony matte molds 8 and a plurality of precious antimony molds 13 are arranged in parallel on the frame, and the frame is connected to the tractor through the connector 7; the flue gas concentration sensor and the tractor are both electrically connected to the controller.

[0018] The track passes through the area of ​​the front bed of the blast furnace, and the frame is arranged on the track. The antimony matte mold and the precious antimony mold are both detachably assembled with the frame. The antimony matte mold is provided with an antimony matte hook 9, and after the antimony matte is cooled, it is fixed together with the antimony matte hook for easy demoulding. The dust collector is a pulse bag dust collector.
