煤泥烘干机工作时遇到的堵塞现象，一般分为部分堵塞和完全堵塞这两种情况。煤泥烘干机的堵塞物主要是煤泥烘干机系统中的一些机械杂质，物料中大颗粒物料在输送过程中的结晶物或料液粘度超过输送极限而造成的。煤泥烘干机部分堵塞使物料不能完全烘干，高压泵的压力变化并不明显，但煤泥烘干机出口气体温度会明显提高；如果高压泵的压力突然提高，塔口温度明显升高，这说明煤泥烘干机完全堵塞，但是不管出现哪种情况，都要及时处理，否则会产生大量的废料，甚至会引起煤泥烘干机其他的故障发生。虽然煤泥烘干机在使用过程中会出现堵塞现象，如果您能注意以下几点还是可以预防的：1.采用煤泥烘干机的快开结构，煤泥烘干机的定位采用卡制的方法，不需任何工具在瞬间就能非常方便的装拆煤泥烘干机部件，不但操作方便，而且为处理故障节省许多时间；2.设置监视机、摄像装置，可以观察到烘干状态的位置，然后将烘干状态及时传递到控制室的监视机上，使操作者及时掌握烘干状态，出现故障可以及时发现；3.选择合适的过滤机，过滤料液中杂质，过滤机筛网的选择要与煤泥烘干机人口通道和孔径相适应，通常选择过滤机的网孔直径是煤泥烘干机入通道或孔径的0.2倍即可。4.采用气流压力或复合煤泥烘干机，此煤泥烘干机兼有气流煤泥烘干机和压力式煤泥烘干机的双重功能，开车时高压泵的压力还没有达到烘干压力时用压缩空气进行烘干，待高压泵正常工作时止压缩。

The causes and the prophylactic measures of coal slime dryer blockage Coal slime dryer work encounter blocking phenomenon, generally divided into partial blockage and completely blocked the two cases. Coal slime dryer stemming mainly coal slime dryer system of some mechanical impurities, and large particle material in the material in the crystal in the process of conveying or liquid viscosity than feeding the limit. Coal slime dryer partial blockage of material is not fully dry, high pressure pump pressure change is not obvious, but coal slime dryer exit gas temperature can obviously increase; If the high pressure pump pressure suddenly raise, tower mouth temperature increased significantly, suggesting that slime dryer is completely blocked, but no matter what kind of situation, should be treated in a timely manner, otherwise it will produce large amounts of waste, and even cause coal slime dryer other failure. Although coal slime dryer in use process will appear jams phenomenon, if you can pay attention to the following points still can prevent: 1. Adopt the quick opening structure of coal slime dryer, coal
