一、前言盘式真空过滤机是连续工作的过滤设备，但是对每块过滤扇形板来说，它的工作却是间断的，需要经过过滤、干燥和卸料三个工序来实现一个完整的工作循环，见图1。在三个工作区的中间均有过渡区Ⅱ、Ⅳ、Ⅵ，过渡区是死带，其作用是防止滤扇从一个工作区转入另一个工作区时 I. INTRODUCTION Disc vacuum filter is continuous working filtration equipment, but for each filter fan, its work is intermittent, need to go through three steps of filtering, drying and unloading to achieve a complete job Loop, see Figure 1.

The transition zone is dead belt, which is used to prevent the filter fan from being transferred to another work zone from one work zone
