摘要 在生活中家里的洗菜池有污物过滤网，但是需要人为定期清理污物，经常会忘记清理导致污物流入下水道，即使是及时清理，也难免有一些污物流走，虽然每次进入下水道的污物比较少，但是时间长了，人数多了就会导致下水道堵塞，海水污染。 本次设计所研究的“下水道固液分离装置设计”，比较全面的描述了下水道固液分离装置设计的全过程，从固液分离的性能分析开始，相继对装置结构形式、分离装置设计、叶轮模具设计等问题，系统的论述了下水道固液分离装置的设计过程。设计中拟采用全三维结构设计技术，利用SolidWorks三维软件对固液分离装置进行三维建模，确定了分离装置、传动装置、动力装置的整体布局等，并进行了叶轮叶片的塑件工艺分析、成型零件设计、拟定模具结构、用CAD软件绘制模具的二维图，明了的展示了整体装置的结构和叶轮叶片的模具结构。 关键词：固液分离；注塑模具；三维设计 ABSTRACT I
