一、概述 青海察尔汗盐湖盐田光卤石矿溶解重结晶制取氯化钾工艺,可用老卤卤水与光卤石点卤水按比例进行兑卤,快速结晶出光卤石矿,疏干矿层后就地加入一定比例的淡水,将光卤石矿溶解,然后将溶解液泵入钾盐池,重新结晶制取氯化钾产品。这一工艺的重要环节是溶矿,而溶矿的关键则是加速溶矿的设备。目前国内外尚无合适的溶矿定型设备。我们针对溶矿条件和矿物特性,并总结了1982年的小试验,在水利、船舶、农机等单位的协作下,研制出了旋耕搅拌船。旋耕搅拌船的作用是:用旋耕刀及辅助的喷水射流对光卤石矿层,按一定深度逐步翻搅,以加速光卤
I. Overview Qinghai Chaerhan Salt Lake carrageenan Yalian dissolved recrystallization Preparation of potassium chloride process, available old brine and carnallite brine brine in proportion to brine, the rapid crystallization of carnallite, after the dry layer Add a certain proportion of fresh water in situ, the carnallite dissolved, and then pump the solution into the potassium salt pool, recrystallization of potassium chloride products. An important part of this process is to dissolve ore, while the key to dissolving ore is to speed up the equipment for ore-dissolving. At present, there is no suitable type of dissolution equipment at home and abroad. We focused on the conditions of dissolved minerals and minerals, and summarized the small pilot in 1982, in the water conservancy, shipbuilding, agricultural machinery and other units in collaboration, developed a rotary trencher. The role of rotary tugboat is: Rotary trowel and auxiliary water jets carnallite rock layer, according to a certain depth gradually stir to accelerate Halogen
