摘要:

针对耙式浓缩机占地面积大、煤泥水浓缩效率低,老式倾斜板浓缩机容易发生堵塞且清理比较困难等问题,云南科力新材料有限公司(原昆明冶金研究院)自行研制出斜窄流浓密机。该设备结构简单,操作方便;内部倾斜板材料为改良后的聚丙烯,使用寿命长且能有效避免物料在板面结块。该机在云南后所选煤厂用于煤泥水处理的工业试验结果显示,其在运行过程中能有效克服老式倾斜板浓缩机易堵塞等缺点;同样的能耗条件下,其单位面积处理能力高出现场使用的Φ28m耙式浓缩机3倍以上,并且能获得更高的底流浓度。斜窄流浓密机顺应当今选煤厂煤泥水浓缩设备发展方向,具备极大的市场推广价值。

Abstract:

Compared with rake thickener covering a large area but having low concentration efficiency and old-fashioned lamella thickener prone to clogged up in operation and difficult to clean up, lamella thickener operating in tilting slender up-flowing developed by Yunnan Keenly New Materials Co. Ltd. (former Kunming Metallurgical Research Institute) has simpler structure, more convenient operation and overcomes their disadvantages. The device’s internal inclined plates are made of modified polypropylene. They can avoid coal slime agglomeration on the plates’ surface and have long service life. The industrial test results show that tilting slender up-flowing lamella thickener isn’t easy to clogged up during operation, consumes lower energy and gets higher underflow concentration. Its unit area processing capacity is 3 times larger than that of Φ28m rake thickener.

Key words: tilting slender up-flowing lamella thickener, industrial test, coal slurry concentration
