,具体涉及一种物料清堵装置。
技术介绍
最近几年随着电厂所用煤种的多样性,有许多电厂反映给煤机进口部位频繁出现煤粉堵塞问题,尤其是给煤机进口插板阀也频繁出现堵塞卡死的问题,影响了机组的安全稳定运行。煤仓之所以堵塞,经调查发现出现以上问题的原因如下:火力发电厂在投运后,其燃料来自不同的矿点,杂质含量、粘度也不同,另外雨季时物料潮湿容易粘结,冬季寒冷容易冻结,特别是随着煤中水分的增加,煤的团聚性急剧增大,煤在煤斗内向下流动的过程中受到仓壁的挤压力越来越大,本来松散的颗粒被挤压团聚,特征尺寸变得很大,当煤团的特征尺寸达到一定的临界值,堵塞就会发生;另外潮湿的煤在下料口内粘壁板结也使得下料口变得日益狭窄,堵塞的几率随之增加;还有就是插板阀部位煤粉容易结块,如若不及时清理会出现粘壁堵塞问题。授权公告号“CN201980614U”的专利文献公开了一种旋转煤斗疏松机,具有固定的上短筒、可旋转的旋转体、固定的下短筒、刮刀,旋转体位于上短筒与下短筒之间,刮刀从上短筒内壁延伸至下短筒内壁,刮刀上端与上短筒固定,刮刀下端与下短筒固定,能够刮 ...
