云南三环化工有限分公司采用NXZ-25高效深锥浓密机对磷矿浆进行浓密,在实际生产中出现浓密机溢流澄清水“跑浑”现象、底流含固量达不到设计要求和转耙出现埋死等问题。针对这些问题对磷矿浆进料位置、给料井结构及絮凝剂投加点进行了技术改造,消除了溢流澄清水“跑浑”现象,减少转耙的阻力和压耙事故的发生,同时还提高了深锥浓密机的处理能力和底流浓度,取得了较好的经济效益。 Yunnan Sanhuan Chemical Co., Ltd. adopts NXZ-25 high-efficiency deep cone thickener to thicken the phosphate slurry. In actual production, there appears thickener overflow, “running muddy” phenomenon, and the underflow solid content does not reach the design Demands and turn rakes appear buried and other issues. In response to these problems, the technological transformation of phosphate slurry feed location, feed well structure and flocculant dosing point has been carried out, eliminating the phenomenon of overflowing clear water and running muddy water, reducing the resistance of dragging harrow and the occurrence of pressure rake accidents , While also increasing the processing capacity of deep cone thickener and underflow concentration, and achieved good economic benefits.
