Abstract

本发明涉及一种具有柔性密封膜的反应釜，组成包括罐身、罐盖，罐盖中央开设圆孔，圆孔上方固定有支架，支架内设置有密封球面轴承，密封球面轴承的球体连接搅拌轴，密封球面轴承的轴承箱与支架固定，圆孔与球体之间固定有柔性密封膜，柔性密封膜与支架之间形成密封腔，该密封腔内注满纯水。本发明反应釜使用球轴承实现搅拌桨全方位的搅动，不留死角；选用柔性密封膜密封，使得内部罐内气体不泄露，有效保护操作人员且不会对环境造成污染；由于密封膜上方的密封腔内注有水，因此当罐内压力变化时，密封腔能够对密封膜起到良好的支撑作用，因此密封膜不会鼓起或塌陷，也就不会受到额外的张力，因此不易破损，使用寿命更长。

Description

一种具有柔性密封膜的反应釜
技术领域
本发明涉及一种化工反应釜。
背景技术
现在市面上大多数用于制备印染助剂的反应釜没有设置搅拌装置，使得反应的物料搅拌不充分和不均匀，这就直接导致反应速度慢，且反应不完全，浪费了资源，提高了生产成本，且反应后罐内残留下的一些反应介质容易腐蚀，影响了反应设备，不能提高经济效益。
为了解决上述问题，中国实用新型专利CN203123964U，公开了一种用于制备印染助剂的反应装置，其在罐盖上安装有伸入于罐身内的搅拌轴，搅拌轴底端安装有锚形桨叶，实现对物料的搅拌，加快反应速度。
然而某些印染助剂在制备过程中有有害物质挥发出，因此需要在密闭环境中进行搅拌。传统带搅拌反应釜大多采用填料密封或机械密封，填料密封的密封性能差且阻力大、易损耗；而机械密封则价格高，使用一段时间后密封性能下降，维护更换成本高昂。
此外，有时反应需要一定的加热环境，传统只能通过对罐体加热来实现对物料的加热，加热速度缓慢且罐内物料温度不均匀，不利于反应的顺利进行。
发明内容
本发明的目的在于：克服上述现有技术的缺陷，提出一种化工反应釜。
为了达到上述目的，本发明提出的化工反应釜，组成包括罐身、罐盖、搅拌电机、搅拌轴、搅拌桨，所述罐身上设有投料口、出料口，其特征在于：所述罐盖中央开设圆孔，圆孔上方固定有支架，所述支架内设置有密封球面轴承，所述密封球面轴承的球体连接搅拌轴，密封球面轴承的轴承箱与支架固定，所述圆孔与球体之间固定有柔性密封膜，所述柔性密封膜与支架之间形成密封腔，该密封腔内注满纯水；所述罐身底部安装有电加热管，所述电加热管上方的罐身内壁固定有朝斜下方向喷射的喷嘴，所述电加热管下方的罐身底部固定有抽水口，所述罐身外设置有将抽水口与喷嘴连接的管路，管路上安装有水泵。
本发明化工反应釜，进一步的改进在于：
1、所述罐盖上安装有观察口。
2、所述罐盖上安装有插入罐身内的温度计。
3、所述柔性密封膜呈环形，内外侧分别通过法兰与球体、罐盖圆孔密封连接。
4、所述罐盖与罐身的接口处卡装接合。
5、所述罐盖上安装有排气管，所述排气管上装有泄压阀。
6、所述喷嘴的喷射方向与搅拌轴转动方向相反。
本发明反应釜使用球轴承实现搅拌桨全方位的搅动，不留死角；选用柔性密封膜密封，使得内部罐内气体不泄露，有效保护操作人员且不会对环境造成污染；由于密封膜上方的密封腔内注有水，因此当罐内压力变化时，特别是压力大幅增加时或压力急剧降低时，密封腔能够对密封膜起到良好的支撑作用，这是因为当外界压力变化时液体的体积随几乎不发生变化，因此密封膜不会鼓起或塌陷，也就不会受到额外的张力，因此不易破损，使用寿命更长。
故，本发明所用的密封结构成本低廉，且能够承受罐内不同的压力变化，具有更强的适应性。
此外，罐身内设置有电加热管，能够对物料进行加热，并且采用水循环喷射的方式提高加热的均匀度，能够迅速将热量传递给罐身内的物料，实现对物料加热的目的，比传统不带加热或者对罐身加热的设备，本发明反应釜能够使物料更均匀的被加热，提高物料的反应速度和平稳性，进一步提高生产效率。

除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
