A pressure filtering dehydration device comprises a plurality of filtering plates (filtering devices (20)), annular filtering cloth (14), a driving roller (41) and a cleaning mechanism (50). The plurality of filtering plates can be movably supported between a front frame (11) and a rear frame (12) in a pressing joint state and a separating state. The annular filtering cloth is supported among the filtering plates, and the filtering surfaces of the filtering cloth are opposite to each other. The driving roller enables the filtering cloth to move under a separating state. The cleaning mechanism is used for cleaning the filtering cloth. The driving roller (41) is arranged on the downstream side of the cleaning mechanism (50) along the running path of the annular filtering cloth (14). According to the invention, residues are prevented from being attached to the filtering cloth so that the filtering cloth crinkles, swings and the like, and the device can stably work for a long period of time. |
