骨素真空浓缩设备中关键辅件的优化设计

摘要

To solve the problems such as material escape,vulnerable to pollution of materials and equipment,difficulty cleaning,and so forth,the three key accessories of preventing material escape device,auto-drainer of condensate water and sight glass devices in vacuum concentration equipment were optimized.The prevent material escape used the screen gas-liquid separation device the centrifugal gas-liquid separator to capture,and the fast-loading trap cylinder within the cover was designed in order to achieve the overall cleaning and replacement.Condensate drain was realized by the automatic drain device with no pump.Under the pump-free conditions,only by using the compressed air powered,the liquid discharge of condensate reached a certain level.The three key accessories have the characteristics of simple structure,easy operation,highly secure,wide range of application.It has high popularization and application value.%为解决真空浓缩过程中物料损失、原料及设备易受污染、清洗困难等问题,对真空浓缩设备中的防跑料装置、冷凝液排出装置和观察视镜3个关键辅件进行了优化设计.防跑料装置使用丝网气液分离器及离心式气液分离器进行捕集,设计快装式捕集器盖以实现内筒体整体清洗及更换;设计了无泵自动排水装置,在无泵状况下,只使用压缩空气为动力,将冷凝后达到一定液位的液体排出.优化设计后的3辅件结构简单、易操作、安全系数高、适用范围广.改进后的浓缩设备具有较高的推广和应用价值.
