Steam curing kettle for preparing alpha-semi-hydrated gypsum by semi-dry method
The invention relates to the technical field of chemical engineering, in particular to a steam curing kettle for preparing alpha-semi-hydrated gypsum by a semi-dry method, the device is generally divided into three parts: a stirring kettle, a pressurizing cabin and the steam curing kettle, the stirring kettle comprises a feed port, a kettle body, a spiral stirring rod and a hanging ring, and gypsum slurry and a crystal modifier enter the stirring kettle through the feed port and then are fully stirred; the pressurizing cabin comprises an upper valve, a lower valve, a humidity sensor, a pressure sensor, a pressurizing pump and a pressure sensor, when the pressure is insufficient, the pressurizing pump supplements pressure, and after the pressure of the pressurizing cabin and the pressure of the steam-curing kettle are balanced, the valves are opened to feed materials into the steam-curing kettle; the steam-curing kettle comprises a rotary kiln, a heating wire, a temperature sensor, a humidity sensor, a pressure sensor, a pressurizing pipe, a water vapor pipe, a control module and a pressure release valve, after slurry is injected into the steam-curing kettle, the pressurizing pipe and the water vapor pipe provide pressure and water vapor for the reaction kettle, and the temperature sensor and the humidity sensor detect the environment in the kettle all the time; and the collected data is transmitted to the control module so as to achieve the most suitable reaction condition.
本发明专利涉及化工技术领域，具体是一种半干法制备α‑半水石膏的蒸养釜，装置大体分为三部分：搅拌釜、加压舱、蒸养釜，搅拌釜包括进料口、釜体、螺旋搅拌棒、吊环，石膏浆料与转晶剂通过进料口进入搅拌釜后进行充分搅拌；加压舱包括上下两个阀门、湿度传感器、压强传感器、增压泵，压力传感器，当压力不足时增压泵进行补压，加压舱与蒸养釜压强平衡后打开阀门投料到蒸养釜；蒸养釜包括一个旋转窑、加热丝、温度传感器、湿度传感器、压强传感器、加压管、水蒸气管、控制模块、泄压阀，料浆注入到蒸养釜后，加压管、水蒸气管为反应釜中提供压强与水蒸气，温度传感器、湿度传感器时刻检测釜内环境，将采集的数据传输到控制模块，以达到最适合的反应条件。
