International ClassB01D 033/06AbstractA method and apparatus for efficiently separating solids from liquid/solid slurries are disclosed. The slurry to be separated is retainably placed within a container having one or more lift paddles secured within its inner cavity. The container is supported for rotation about an axis and has drive means for slowly rotating the container. As the container rotates, the lift paddles lift a portion of the retained slurry, allowing the liquid portion to fall back into the primary slurry pool to be separated, and lifting coarse solids toward the top of the rotation path of the paddles. The separated solids slide by gravity from the lift paddles as they approach the top of their rotation paths and into a collection tray. A filter that rotates with the container filters fine solids from the liquid portion of the slurry and also deposits the fine solids on the collection tray. The filtered liquids can be readily pumped from or recirculated to the separator. The collection tray reciprocates about a longitudinal axis to move the collected solids from the separator, collection or transport. Continuous flow-through and multiple chamber separation containers are disclosed.Other References
