浅槽重介分选机上升流系统防堵优化解析

Analysis of anti-blocking optimization of upwelling system of shallow slot heavy medium separator

重介浅槽分选机作为神东洗选中心各选煤厂分选块煤的关键设备,以其大规模处理能力、低能耗、小占地面积和较高的分选精度而广泛应用。聚焦上湾选煤厂305#浅槽工艺系统的技术改进,在初次实施方案不理想的情况下,优化实施方案。经过3个月的实施效果追踪,浅槽上升流堵塞的频率较之前降低了80%以上,有效降低了吨煤生产成本,提升了生产组织的可靠性,确保了洗选产品质量的稳定性,并形成了成熟且可靠的技术成果,这些成果能够为集团内其他单位浅槽上升流防堵优化改造提供指导。

The dense medium shallow trough separator,as the key equipment of lump coal separation in Shendong washery,is widely used for its large-scale handling capacity,low energy consumption,small occupation area and high separation precision.This study focuses on the technical improvement of 305#shallow trough process system in Shangwan coal preparation plant,which is optimized and implemented after the initial implementation plan is not satisfactory.After three months of implementation,the results show that the frequency of upward flow clogging in shallow grooves has been reduced by more than 80%,the production cost per ton of coal has been effectively reduced,and the reliability of production organization has been improved,it ensures the stability of the product quality,and forms mature and reliable technical results,which can provide guidance for other units in the group to improve the anti-clogging optimization.
