磨片式固液分离机的设计 摘要 对磨片式固液分离机的结构和工作原理进行设计和说明，从而优化分析设计出符合实际效用的固液分离机。 在方案设计中，通过选择计算，确定磨片式固液分离机的电动机的型号为Y100L2-4、Y80M2-4；通过设计计算，确定减速器的相应的参数；通过系统设计和结构设计，确立定片、动片以及螺旋轴的设计参数，完成磨片式固液分离机的设计。 总体而言，磨片式固液分离机是一种新型式的分离机，其动力由螺旋轴推进，动、定片间隔组成一组或几组过滤单元，从进口到出口，螺旋轴螺距逐渐变小，物料在动定片腔内的压力增大，使水从动片与定片间隙滤出，而且在出口处设置背压板增加内部压力实现连续快速脱水。从而提高了生产效益和物料利用率，降低了生产成本，还能避免浪费和污染，有利于保护生态环境。 关键词：实体模型；电动机；减速器；螺旋轴；固液分离机 ABSTRACT The structure a
