摘要：【中文】本发明提供一种提高利用率的洗煤工艺，设定其中一种原煤，设定原煤重量为M时，杂质重量为m0，则精煤成分的重量为m＝M‑m0,精煤率为A＝m/M；通过传送带向洗煤机内传输预设重量的原煤M；原煤进入所述洗煤机内，下端的出煤口封闭，打开重悬浮液泵，向洗煤机内注入预设重量m1的重悬浮液，精煤及悬浮液通过过滤板进入上方，中煤及矸石下沉至底部，并通过第一油缸向下移动第一预设距离D1同时，使精煤及悬浮液充分的在上端停留，打开出煤口，使下端的液体及中煤、杂质进入下方的储煤小车，至储煤小车的重量为(m1+M)/5。 【EN】The invention provides a coal washing process for improving the utilization rate, wherein one raw coal is set, when the weight of the raw coal is set as M, the weight of impurities is M0, the weight of clean coal components is M-M0, and the clean coal rate is A-M/M; conveying raw coal M with preset weight to a coal washer through a conveying belt; raw coal enters the coal washer, a coal outlet at the lower end of the coal washer is closed, a heavy suspension liquid pump is opened, heavy suspension liquid with preset weight M1 is injected into the coal washer, clean coal and suspension liquid enter the upper part through a filter plate, middlings and gangue sink to the bottom and move downwards through a first oil cylinder for a first preset distance D1, meanwhile, the clean coal and the suspension liquid are enabled to fully stay at the upper end, the coal outlet is opened, liquid at the lower end, the middlings and impurities enter a coal storage trolley below the coal storage trolley, and the weight of the coal storage trolley is (M1+ M)/5.
