选煤厂带式输送机的问题分析与改进
|
摘要
针对选煤厂带式输送机生产时出现最为常见的输送带跑偏事故,进行总结归类,对不同类别的跑偏现象,分别分析出其产生故障的原因。结合当前一线工人普遍使用的对策,提出了机械优化和人工操控两方面的改进措施。改进后的带式输送机在一定程度上能够自动向中心移动,防止煤的卷入,确保跑偏现象不再出现,提高选煤厂的生产效率,具有较大的推广价值。
Most common belt deviation accidents occurs during the production of belt conveyors in coal preparation plants.The classification and classification are carried out. The causes of faults are analyzed for different types of deviations.Combined with the countermeasures commonly used by current frontline workers,improvements in mechanical optimization and manual control are proposed. The improved belt conveyor can automatically move to the center to a certain extent to prevent coal from being caught in,to ensure that the deviation phenomenon does not occur again,and to improve the production efficiency of the coal preparation plant,which has greater promotion value.
