Description

一种避免固体物料堆积的反应釜 技术领域
本发明涉及化工反应釜领域，尤其是一种避免固体物料堆积的反应釜。
背景技术
化工的各类反应中需要反应釜搅拌的叶浆来达到物料的均匀混合，使得反应能够快速平稳地实现。一些反应过程中往往需要添加固体的原料，一般通过投料口进行添加，由于内部反应液都是液体形态，有些固体粉末类原料很难溶在液体反应液中，形成局部的堆积。对于这种固体粉末类原料，采用加高温度或者加大搅拌速度来达到固液的混合，往往需要较长的时间，有时会影响反应产生一些副反应，同时也增加了能耗，并且堆积的物料在下落过程中表面的摩擦会产生一定的有害的静电，这种静电会给安全带来隐患。现在通用的各类搅拌叶浆往往很难快速地将粉料融入反应液中。另一方面，现有的搅拌叶浆通常与搅拌棒固定，若搅拌叶浆损坏需连同搅拌棒一同更换，造成成本损失。
发明内容
发明目的：为解决上述技术问题，本发明提供一种避免固体物料堆积的反应釜。
技术方案：本发明提供的技术方案为：
一种避免固体物料堆积的反应釜，包括：釜体和搅拌器，釜体顶部设有进料口1；搅拌器包括搅拌棒2，搅拌棒2顶端伸出釜体顶部并连接有手柄，搅拌棒2的中下部设有固定架3，固定架3上均匀设有若干可拆卸的带式螺旋搅拌叶4，带式螺旋搅拌叶4的长度方向与搅拌棒2的长度方向平行。
进一步的，所述搅拌棒2为可伸缩棒。
进一步的，所述固定架3为圆环形板，圆环形板的中心圆孔内壁设有内螺纹，搅拌棒2的中下部外壁上设有与内螺纹相匹配的外螺纹，圆环形板与搅拌棒2通过螺纹结构旋接；圆环形板的板面与釜体横截面平行。
进一步的，所述圆环形板板面上均匀设有通孔，通孔内壁设有螺纹，所述带式螺旋搅拌叶4顶部通过螺纹结构与通孔旋接。
进一步的，还包括定位板5，定位板5上设有与圆环形板上通孔位置相对应的固定槽，所述带式螺旋搅拌叶4底部与对应固定槽卡接。
有益效果：与现有技术相比，本发明具有以下优势：
