针对寒冷天气下带式输送机的滚筒由于粘附冻煤造成胶带跑偏、洒煤现象严重、损坏皮带刮板等问题,提出通过在滚筒内部增设电加热装置,提高滚筒外侧温度的方法.该方法可以有效避免由于气温低造成运输物料冰冻而影响皮带运输机正常生产的问题.“,”Based on the belt conveyor roller belt running deviation under the cold weather, due to serious adhesion frozen coal, the damage of the belt scraper and other issues, the drum of adding electric heating device was put forward, which improved the roller outer temperature and can effectively avoid freezing transport materials due to low temperature that affected the normal production of belt conveyor.
