Separating tank and slag-iron separating system

The invention discloses a separation tank and a slag-iron separation system. The system comprises a separation tank, a blast furnace, an iron runner, a slag flushing nozzle and a torpedo tank, an iron outlet of the blast furnace is connected with an iron slag opening of the separation tank through the iron runner, the slag flushing nozzle corresponds to a slag opening of the separation tank, and the torpedo tank corresponds to an iron opening of the separation tank. An iron storage type main channel and a swing chute are omitted, the stokehold labor intensity is relieved, the consumption of refractory materials is reduced, and the ironmaking production cost is reduced. 本申请公开了一种分离罐以及渣铁分离系统。该系统包括分离罐、高炉、铁沟、冲渣嘴以及鱼雷罐，其中高炉的出铁口与分离罐的渣铁口通过铁沟连接，冲渣嘴与分离罐的渣口对应设置，鱼雷罐与分离罐的铁口对应设置。本申请取消了贮铁式主沟和摆动溜槽，减轻了炉前劳动强度并降低耐火材料消耗，降低了炼铁生产成本。
