Description

一种化工反应釜A chemical reaction kettle

技术领域 technical field

本发明涉及一种化工反应釜。 The invention relates to a chemical reaction kettle.

背景技术 Background technique

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。 At present, most of the reaction kettles used for the preparation of printing and dyeing auxiliaries on the market are not equipped with stirring devices, which makes the reaction materials not stirred sufficiently and unevenly, which directly leads to slow reaction speed and incomplete reaction, which wastes resources and improves production. cost, and some reaction medium remaining in the tank after the reaction is easy to corrode, which affects the reaction equipment and cannot improve economic benefits.

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。 In order to solve the above problems, Chinese utility model patent CN203123964U discloses a reaction device for preparing printing and dyeing auxiliaries, which is equipped with a stirring shaft extending into the tank body on the tank cover, and an anchor paddle is installed at the bottom of the stirring shaft Leaves, realize the stirring of the material and speed up the reaction.

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。 However, some printing and dyeing auxiliaries have harmful substances volatilized during the preparation process, so they need to be stirred in a closed environment. Most of the traditional stirred reactors use packing seals or mechanical seals. The packing seals have poor sealing performance, large resistance, and are easy to wear; while mechanical seals are expensive, and the sealing performance decreases after a period of use, and the maintenance and replacement costs are high.

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。 In addition, sometimes the reaction requires a certain heating environment. Traditionally, the heating of the material can only be achieved by heating the tank body. The heating speed is slow and the temperature of the material in the tank is not uniform, which is not conducive to the smooth progress of the reaction.
