摘　　要：九龙生产部针对浮选原料池料位不稳的状况,对浮选入料泵进行智能控制改造。方案实施后,稳定了浮选原料池内液面高度,实现了浮选入料量的相对稳定,杜绝了人工调整滞后的不利影响,提高了浮选分选指标的稳定性,稳定了浮选精煤灰分,降低了浮选油耗,提高了浮选尾矿灰分和浮选抽出率,从而提高了精煤回收率。Based on automatic control,Jiulong Production Department of Matou Washery carried out intelligent control transformation on the flotation feed pump.By stabilizing the liquid level in the flotation raw material pool,it realized the relative stability of flotation feed,eliminated the adverse effect of manual adjustment lag,improved the stability of flotation separation index,stabilized the ash content of flotation cleaned coal and reduced flotation oil consumption,The ash content of flotation tailings and flotation extraction rate are improved,so as to improve the recovery of clean coal.
