青岛港1600t/h斗轮式矿石卸船机是“八五”国家重点企业技术开发项目的研究成果。该机采用螺旋漏斗作为垂直提升机到臂架胶带机间的物料转载装置,为适应粉矿物料流动性差且粘结性大、块矿物料磨蚀性大的特点,在螺旋漏斗上采取了相应的防堵抗磨的措施以改进螺旋漏斗的性能,卸船机投入使用后的实践证明,这些措施是有效的。本文首先研究螺旋漏斗堵塞的机理;其次分析斗轮式矿石连续卸船机螺旋漏斗堵塞的原因及所采取的防止其堵塞的措施的可行性;最后介绍为此所做的模型试验及卸船机投入使用后螺旋漏斗的有关情况。
Qingdao Port 1600t / h bucket wheel ore ship unloader is “85” research project of state key enterprise technology development. The machine uses the spiral funnel as a material transfer device between the vertical hoist and the boom tape machine. In order to adapt to the poor fluidity of powder ore material and large cohesiveness and large abrasiveness of lump ore material, the machine adopts a corresponding Anti-wear and anti-wear measures to improve the performance of the spiral funnel, put into operation after the ship unloader proved that these measures are effective. In this paper, the mechanism of plugging of spiral funnel is studied first, then the reason of plugging of spiral funnel of continuous ship unloader of bucket wheel and the feasibility of measures to prevent its plugging are analyzed. Finally, the model tests done for this and unloader Put into use after the spiral funnel situation.
