非木纤维连蒸设备结构的改进

Structural Improvement of Continuous Tube Digester for No-Wood Fibers

国内普遍采用横管连续蒸煮系统处理非木纤维,此过程中因设备结构不合理而出现备料过程漏料严重,出料不匀的现象,还因为规模不断扩大导致蒸煮管尺寸变大,使得设备过于笨重。针对原设计平盖封头结构过厚,提出设备的结构改进:过渡料仓采用双排设计的特殊结构散料辊、用螺旋收集原料后外送代替原倾斜皮带提升原料后外送;用外压型凸型封头结构替代蒸煮管平盖封头结构。生产实际应用表明:改进设备结构后不仅解决了上述实际应用中的问题,而且安全可靠、密封良好,制造成本更低。

The horizontal tube continuous cooking system is widely used in non-wood fiber materials process in China,but some equipments structure are not good-enough.For example,the serious leakage and the discharging unevenness of the transition bin,the thickness of the cooking tube flat cover is so large because of the large size of the tube,which lead to the equipments used here is too heavy.So we put forward the structure of the equipment could be improved,such as using the double bulk material roller and output screw for the collecting raw material instead of the inclined belt output in the transition bin,using external pressure type convex head structure instead of flat cover structure of the tube,etc..The actual production application shows that the equipments structure improvements are very practical,not only can solve the problem of practical application,safe and reliable,good sealing,and at the same time consume lower manufacturing costs.
