ABSTRACT:
The inner assembly of a tube pressure filter comprises a supporting member or core (6) on which there is a facing assembled from laths (40). Each two adjacent laths (40) define between themselves a duct (42) and an aperture (44). In use, a filter element is provided on the outer surface of the facing. Filtrate passing through the filter element goes through the apertures (44) into the ducts (42) and then flow longitudinally of the inner assembly to a filtrate outlet. After filtration is complete, compressed air may be passed through the ducts (42) and apertures (44) to assist the discharge of filter cake from the filter element.
In another embodiment (FIG. 6), a filter plate unit for a plate filter press comprises a recessed filter plate (102) of which the base of the recess is provided with a facing (112) made up, for example, of a plurality of laths (114). Adjacent laths (114) define between them a duct (116) and an aperture (118), the aperture (118) providing communication between the duct (116) and the region between the facing (112) and a filter cloth provided over the facing. In use of the filter plate unit, filtrate passing through the filter cloth passes through the apertures (118) into the ducts (116) to be discharged through the ports (128).
