KR powder spraying melt desulfurization stirring device
The invention belongs to the field of hot metal pretreatment desulfurization equipment, and particularly relates to a KR powder spraying melt desulfurization stirring device. A first wheel hub (201) and a second wheel hub (202) are arranged on the upper side and the lower side of a stirring blade (1); a spray pipe (4) is fixed to the middle of a stirring shaft (3) in a sleeving mode; a branch pipe(5) is fixedly arranged in the inner cavity of the first wheel hub (201); one port of the branch pipe (5) communicates with the lower port of the spray pipe (4); the other port of the branch pipe (5)communicates with a first injection mechanism (8); an annular circulating cooling cavity (2011) is formed in the first wheel hub (201); a cooling sleeve (9) sleeves the spray pipe (4) at a certain distance; a cooling gas channel (10) is formed between the inner wall of the cooling sleeve (9) and the outer wall of the spray pipe (4); and a communicating pipe (11) is arranged between the cooling gas channel (10) and the annular circulating cooling cavity (2011). The KR powder spraying melt desulfurization stirring device is simple in structure, high in stirring force and high in desulfurizationefficiency.
本发明属铁水预处理脱硫设备领域，尤其涉及一种KR喷粉熔体脱硫搅拌装置，在搅拌叶片（1）上下两侧设有第一轮毂（201）及第二轮毂（202）；在搅拌轴（3）的中部固定套有喷管（4）；在第一轮毂（201）内腔固定设有分歧管（5）；分歧管（5）的一端口与喷管（4）的下端口相通；分歧管（5）的另一端口与第一喷吹机构（8）相通；在第一轮毂（201）内设有环形循环冷却腔（2011）；在喷管（4）外相隔一定距离套有冷却套管（9）；所述冷却套管（9）的内壁与喷管（4）外壁之间形成冷却气体通道（10）；在冷却气体通道（10）与环形循环冷却腔（2011）之间设有连通管（11）。本发明结构简单，搅拌力强，脱硫效率高。
