本申请以申请日为“2023年5月12日”、申请号为“202310540828.5”、发明创造名称为“一种污泥处理装置”的中国专利申请为基础，并主张其优先权，该中国专利申请的全文在此引用至本申请中，以作为本申请的一部分。
【技术领域】
本发明主要涉及污泥处理技术领域，特指一种污泥处理装置。
【背景技术】
污水厂或其他污染水体产生的污泥，若要将污泥妥善处置，则需要对污泥进行脱水处理，因其主要是由细菌真菌活体细胞及其形成的菌胶团和水形成的固液混合物。目前在处理技术上普遍存在污泥粘性大、脱水困难、能耗高、处理成本高、处理工艺复杂等问题。
对于污泥处理，常用的处理方式有污泥经高温热水解或者添加部分助剂如酸碱调理后水解再进行机械脱水，此类技术目前在运用中，还存在以下问题:在目前热水解反应釜技术中，主要通过往反应釜中通入蒸汽起到污泥加热作用，但是在实际运行时因污泥粘度高，流动性差，容易出现加热效率不佳或加热不均匀问题。还有部分反应釜会设置有搅拌装置以加强受热及水解反应，但因污泥流动性差，常规的搅拌方式并不能使污泥达到充分的混合及流动效果。同时因污泥中存在泥沙及其他颗粒物质，反应釜的搅拌装置一般以较低转速运行，否则将引起因搅拌轴过长导致搅拌密封受损或底部轴承座磨损过快问题，导致设备需要停机进行维护，不仅增加了维护的工作量，停机维护还会影响工作效率，且更换底轴还造成了设备使用成本增加的问题，这些问题是本领域多年一直未能解决的难题。

在本发明的一些实施例中，所述反应罐内部设有搅拌轴，所述驱动组件设置在所述反应罐的顶部，所述搅拌轴的一端通过万向节与驱动组件相连，所述搅拌轴的另一端通过套筒与底轴相连。

本实施例中，换热夹层1上设置有换热介质进口11和换热介质出口12，换热介质进口11用来导入换热介质，换热介质出口12用来导出换热介质；换热介质用来与反应罐2内的物质实现换热，完成反应罐2内物质的升温或降温作业。因反应罐2内具有充分翻滚搅拌功能的特性，可以在污泥完成反应后，利用换热夹层1对反应罐2内的污泥的热量进行回收，具备进一步降低能耗成本的优点。
本实施例中，换热夹层1上还设有用于加热换热介质的加热组件8。通过加热组件8 实现对加热介质快速加热，使得加热介质能快速升温，进一步提高换热介质和污泥之间的换热效率。
