Continuous squeeze-dewatering device
A continuous compression-type dewatering apparatus has a filter chamber (3), a drive shaft (17), a vane (15), and a supply path (50). The filter chamber (3) is delineated by an annular plate (2) and two side plates (1, 1). The drive shaft (17) passes through the center axis of the annular plate (2) and through the inside of the filter chamber (3), and is free to rotate with respect to the filter chamber (3). The vane (15) is disposed within the filter chamber (3), is fixed with respect to the drive shaft (17), and rotates in concert with the drive shaft (17). The supply path (50) passes through the drive shaft (17) and supplies raw fluid to the filter chamber (3). The vane (15) as two side edges (15a, 15a) facing the side plates (1, 1) and an end edge (15b) facing the annular plate (2). The side plates (1, 1) include a screen (4) for separating the raw fluid into a filtered fluid and a cake. The annular plate (2) includes an ejection port (7) for the cake. Inflow pressure of the raw fluid from the supply path (50) into the filter chamber (3) and rotation of the vane (15) causes the filtered fluid to flow out from the filter element (4) to the outside of the filter chamber (3), a cake that remains inside the filter chamber (3) being pushed to the outside of the filter chamber (3) via the ejection port (7).
