Description

一种改进型的聚醚聚合釜
(一)技术领域
本实用新型涉及化学合成反应设备领域，具体一种改进型的聚醚聚合釜。
(二)背景技术
聚醚聚合釜包括釜体、搅拌器、进出料口，釜体壁外部设置有半管夹套结构，半管夹套内通入水蒸气，用于冷却聚合釜中的物料，釜体壁内侧设备有一层热交换盘管，搅拌器安装于搅拌轴，搅拌轴安装于机架，机架上安装有减速机和搅拌电机。其缺点在于：其热交换盘管只设置有一道，热交换率低，不能满足反应物料的温度要求；另外，搅拌器均为折叶桨式搅拌器，其在聚合釜内部能直到良好的物料搅拌效果，但是在聚合釜底部的仍采用折叶桨式搅拌器，其稳定性差，底部物料搅拌效果差，物料容易粘结。
(三)发明内容
针对上述问题，本实用新型提供了一种改进型的聚醚聚合釜，其热交换效率高，能保证反应物料对反应温度的要求，反应物料能充分搅拌均匀，提高反应率。
其技术方案是这样的：其包括釜体，所述釜体壁外侧安装有夹套，所述釜体上部安装有机架，所述机架上安装有减速机，所述减速机上部连接有搅拌电机，所述减速机下部连接有搅拌轴，所述机架内的减速机与所述搅拌轴之间设置有机械密封件，所述搅拌轴上安装搅拌器，在所述釜体内侧安装有热交换盘管，其特征在于：所述热交换盘管设置有两道。
其进一步特征在于：所述热交换盘管包括外盘管和内盘管；所述外盘管与所述内盘管平行安装；所述搅拌器包括底部搅拌器和中部搅拌器；所述底部搅拌器为框式搅拌器；所述搅拌轴包括上搅拌轴和下搅拌轴；所述上搅拌轴与所述下搅拌轴通过连接件连接。
本实用新型的结构中，聚合釜内侧的热交换盘管设置有两道，其能提高热交换率，保证反应物料对温度的要求以及保证反应功效；釜底搅拌器为以框式搅拌器代替折叶桨式搅拌器，增强了整个搅拌器的稳定性，提高了搅拌效果，使物料能够充分反应。
(四)附图说明
图1为本发明主视的结构示意图。
(五)具体实施方式
见图1，本实用新型包括釜体1，釜体1壁外侧安装有夹套2，釜体1上部安装有机架3，机架3上安装有减速机4，减速机4上部连接有搅拌电机5，减速机4下部连接有搅拌轴，机架3内的减速机4与搅拌轴之间设置有机械密封件17，搅拌轴上安装搅拌器，在釜体1内侧安装有两道热交换盘管，依次为外盘管5和内盘管6；外盘管5与内盘管6平行安装；搅拌器包括底部搅拌器7和中部搅拌器8；底部搅拌器7为框式搅拌器；中部搅拌器8为折叶桨式搅拌器；搅拌轴包括上搅拌轴9和下搅拌轴10；上搅拌轴9与下搅拌轴10通过连接件连接.图中，11为进料口，12为进料管，13为人孔，14为耳座，15为蒸汽进口，16为蒸汽出口，18为出料口.
本实用新型结构的聚醚聚合釜为可以实现制造50M3以上容积的聚醚反应，其反应温度易保证，生产效率高，不易产生物料粘结的釜体的特点。
