摘要
介绍一种上进下出，完全敞开无密封，通过湍流实现预乳，靠适度的剪切完成精乳的乳化器。通过检测乳状液游离铵质量分数、粒子直径及产品性能等数据，优化乳化器内部的分散叶片角度、碗形转子周边齿角度及齿数等结构参数，实现6t／h以上产能的乳化器生产出的乳化炸药产品性能符合国标等相关要求的目标。控制乳状液游离铵质量分数在0．20％以下、粒子直径在1．0～5．0μm范围内，确定了分散叶片角度为10°，碗形转子周边齿角度为10°、齿数为30只，在转速960r／min、产能6t／h条件下，乳化炸药产品储存6个月后爆速4500m／s、猛度15mm。
A over-entering and down-out and completely open unsealed emulsifier was introduced in this article. Pre- milk through turbulence and completed fine milk by moderate shear was achieved. Free ammonium content, particle diame- ter and the product performance data were obtained. Dispersing blade angle, peripheral teeth angle and number of bowl- shaped rotor were optimized. Production performances of emulsion explosives produced by the emulsifier, whose capacity was higher than 6t/h, all met national standards. Under the condition that free ammonium content was controlled below 0.20% and the particle diameter was 1.0-5.0 ~m, dispersing blade angle was 10~, peripheral teeth angle of bowl-shaped rotor was 10~ and peripheral teeth number of bowl-shaped rotor was 30. Keeping emulsifier speed at 960r/min and capacity at 6t/h, performance of products stored over 6 months can still achieve 4500 m/s for the detonation velocity, 15 mm for the fierce degree, and 4 cm for the transmission distance.
