摘　　要：针对辛置选煤一车间原浮选精煤脱水系统存在的问题,对浮精脱水系统进行了改造,引入2台KZG500/1500×2000-U型高效快开隔膜压滤机替换了原圆盘真空过滤机。快开隔膜压滤机投入运行后,降低了精煤水分和滤液浓度,提高了精煤产率和煤泥灰分,改善了作业环境,降低了职工劳动强度。Improve the clean coal dehydration system in Xinzhi coal preparation plant. Disc vacuum filter was replaced by two KZGS00/1500×2000-U diaphragm filter presses with quick-discharge. After improvement, water content of clean coal and filtrate concentration as well as labour intensity is reduced, clean coal yield and slime ash is improved, the operating environment is getting better.
