望峰岗选煤厂堵仓原因及解决方法探索

Reason for coal bunker jam in Wangfenggang Coal Preparation Plant and relevant solution

为了解决望峰岗选煤厂原煤挂仓问题,分析了挂仓原因。由于原煤煤泥量大,煤仓结构不合理,根据煤质和煤仓结构研制了新型水力清仓系统,介绍了其工作原理、具体实施方法,分析了水力清仓技术在望峰岗选煤厂的使用情况。结果表明:通过设计和使用新型原煤仓水力清仓装置,2号煤仓挂壁的原煤由7 000 t降低至1 000 t,大大提高了煤仓的储存能力,为选煤厂、矿井和铁路运输部门的原煤衔接提供更大的缓冲空间,该水力清仓技术可在矿井、火力发电厂、焦化厂、钢铁厂等推广应用。

To solve the problem of raw coal hanging bunker in Wangfenggang Coal Preparation Plant, the reason for raw coal hanging bunker was analysed, Due to the large amount of slime, coal bunker structure is not reasonable, so according to the coal bunker structure and coal quality, a new type of hydraulic cleaning system was developed. Introduced its working principle, implementation method, the actual usage of the hydraulic cleaning technology in Wangfenggang Coal Preparation Plant was also^analysed, The resuits show that＇ae- cording to the design and use of hydraulic device of coal bunker clearance, the quantity of raw coal hanging bunker in No. 2 coal bunker was reduced from 7 000 tons to 1 000 tons, the coal storage capacity was also improved greatly,which can provide a buffer for more coal mines and railway transportation of coal rank, and hydraulic cleaning technology can be used in mine and the thermal power plant, co- king plant, steel plant.
