Abstract
The existing tail coal filter press in the coal preparation plant of Xinjulong Company is relatively outdated,and there are problems such as inability to operate automatically,required manual judgment of the pressure filter material unloading timing,required manual on-site operation of upstream and downstream equipments(bottom flow pump,valve,mixing bucket,feed pump,belt conveyor,scraper conveyor,etc.),and long waiting time after the filter press synchronously reaches the material unloading conditions.In view of the above issues,an intelligent pressure filtration system is designed based on the judgment of the end timing of the filter press feeding,the queuing and material unloading of the filter press,and the upstream and downstream locking control of the filter press.Combined with the hardware repair of the filter press,the transformation of the filtrate flume,the transformation of the filtrate water flow detection,and the centralized control transformation of the upstream and downstream equipments,the intelligence of the tail coal pressure filtration process in the coal preparation plant of Xinjulong Company is achieved,and the production efficiency of the tail coal pressure filtration system is improved by about 18%,which greatly reduces personnel labor intensity,breaks information isolated islands,and basically achieves unmanned operation.关键词
