Description

高粘度自洁反应器 技术领域
本发明涉及聚酯行业的一种生产设备，特别涉及缩聚反应中使用的一种反应装置。
背景技术
现有聚酯生产中，随着缩聚反应的进行，物料的粘度逐渐加大，高粘度的物料会阻碍反应副产物的快速逸出，延缓反应的进行，需要使物料在真空状态下形成较大表面积的膜，这样，反应副产物才能从物料中顺利逸出，反应才能更好地进行下去。为使反应能继续进行，目前，采用一种反应器，其结构主要包括有壳体，壳体顶部设有进料口和真空抽气口，壳体底部设有出料口，壳体内位于进料口下方设有一对或多对相对转动的压辊，压辊之间留间隙，物料从进料口进入，从转动的压辊隙缝之间经过形成膜状，并被不断蒸发，最后从出料口离开装置。其不足之处在于：压辊的成膜效率低，物料粘度大时，容易在壳体内堆积，堵塞，致使装置的工作效能降低；采用双压辊相对转动成膜，其功耗高，处理能力小。
发明内容
本发明针对现有技术的不足，提供一种高粘度自洁反应器的技术方案，旨在解决现有技术中物料成膜效果差，工作效率低下的问题。
　　为解决上述技术问题，本发明的技术方案如下：高粘度自洁反应器，包括壳体，壳体上设有与其内腔相通的真空抽气口，壳体顶部设有进料口，壳体底部设有出料口，所述壳体为卧式设置且两端封闭的圆筒，进料口设置在壳体顶部的一端，出料口设置在壳体底部的另一端，壳体内腔中设有一个可转动的滚筒，滚筒从进料口下方一直延伸到出料口上方，滚筒外周设有与壳体内壁相适配的外推进叶片，滚筒中心同轴设置有中心轴，中心轴外固定设有与滚筒内壁相适配的内推进叶片，滚筒表面设有若干通孔。
　　本发明在使用时，真空抽气口接真空泵，可不断抽走物料反应过程中逸出的气体，中心轴和滚筒均转动，物料从进料口进入，部分物料在外推进叶片的推动下从进料口一端向出料口一端运动，部分物料穿过所述通孔进入滚筒内，在内推进叶片作用下，物料可以向出料口方向运动，也可以向进料口方向推进，视中心轴的转向而定；在上述过程中，物料被推进叶片推进、搅动，自身蒸发面积极度增大，反应副产物迅速被从真空抽气口抽出，物料的缩聚反应能进一步深入进行，反应后的物料最终会从出料口离开装置。该装置体积小、处理量大、能耗低，可用于PET、PEN、PBT、PTT等聚酯的生产中，本发明特别适合处理高粘度的物料。
　　所述外推进叶片为螺旋叶片，内推进叶片也可为螺旋叶片。上述螺旋叶片还可以是推进桨叶。其工作时，均能使物料充分搅动，蒸发迅速。
　　为保证该装置结构简单紧凑，所述滚筒两端设置的滚筒轴经外轴承支撑在壳体上，中心轴两端经内轴承支撑在滚筒轴内。为进一步保证其动力布置合理，滚筒轴的输入端和中心轴的输入端分设在壳体两端。
附图说明
图1为本发明一种结构示意图。
　　其中，1、12皮带轮，2、11滚筒轴，3进料口，4壳体，5通孔，6外推进叶片，7内推进叶片，8滚筒，9中心轴，10真空抽气口， 13内轴承，14外轴承，15出料口。
具体实施方式
如图１所示，为高粘度自洁反应器，其结构主要包括有壳体4，壳体4为圆筒，其卧式设置且两端封闭，壳体4上设有与其内腔相通的真空抽气口10，壳体4顶部设有进料口3，该进料口3设置在壳体4顶部的一端，壳体4底部设有出料口15，该出料口15设置在壳体4底部的另一端，壳体4内腔中设有一个可转动的滚筒8，滚筒8两端的滚筒轴2、11通过外轴承14支撑在壳体4上，滚筒8从进料口3下方一直延伸到出料口15上方，滚筒8外周设有与壳体4内壁相适配的外推进叶片6，外推进叶片6为螺旋叶片，滚筒8中心同轴设置有中心轴9，中心轴9两端经内轴承13支撑在滚筒轴2、11内，中心轴9外固定设有与滚筒8内壁相适配的内推进叶片7，内推进叶片7也为螺旋叶片，滚筒表面设有若干通孔5；滚筒轴2、11的输入端和中心轴9的输入端分设在壳体4两端，可通过两端设置的皮带轮1、12输入动力。
　　工作时，通过真空抽气口10抽真空，动力经皮带轮1、12输入，滚筒8和中心轴9转动，两者可以同向转动，也可以相逆向转动，可视物料的粘度，以及在反应器中需要反应的时间，来确定滚筒8和中心轴9的转动速差，从进料口3进入的物料会在滚筒8内外经通孔5不断相互流动，在外推进叶片6和内推进叶片7的共同作用下，换位、搅拌，自身表面积极度增大，反应副产物充分逸出，使聚合反应更加彻底。
