    Abstract: A filtering apparatus and method is disclosed adapted to filter suspended solids from a liquid, consisting of a filter housing which receives a flexible belt filtering element into a filter chamber, the liquid to be passed through the belt to filter out solids. The flexible belt is movably mounted to be passed through end openings on either side of a filter chamber to enable removal of accumulated solids after each filter cycle. The end openings are sealed during filtering cycles by flexible tube segments extending across the openings which are pressurized to effect a seal and evacuated to allow removal of the belt. A series of such filters may be stacked together with a traveling roller assembly utilized for simultaneously moving the belts of each filter in and out of the chamber.

    Abstract translation: 公开了一种适用于从液体中过滤悬浮固体的过滤装置和方法,该过滤装置和方法由将柔性带过滤元件接纳到过滤室中的过滤器壳体组成,待通过该带以过滤出固体的液体。 柔性带可移动地安装以穿过过滤室两侧的端部开口,以在每个过滤器循环之后能够去除积聚的固体。 端部开口在过滤循环期间通过延伸穿过开口的柔性管段被密封,所述管段被加压以实现密封并抽真空以允许移除带。 一系列这样的过滤器可以与用于同时将每个过滤器的带子移入和移出腔室的行进辊组件堆叠在一起。
