ABSTRACT:
The invention relates to an apparatus for treatment of particulate mixtures such as a mixture of solid particles, which is to be depleted in, enriched by or treated with a fluid, or wherein the mixture acts as a treatment medium for a fluid passing through same. The apparatus is of the type operating with an advancing bed of the particulate material. It utilizes walls permeable by at least a portion of the fluid. The apparatus is of the type of tubular, rectangular or the like vessel having only stationary parts and subdivided by a selected combination of permeable and non-permeable walls into separate chambers into or from which the fluid can be delivered or removed. The movement of the particulate mixture is effected solely by forcing same through a passage having preferably but not exclusively an annular chamber, by pumping, by gravity or by a combination of both. Additional throttling or valve means are employed to selectively control the advancement of the bed through the device. The device is simple in structure and can be relatively easily adjusted for a great variety of different operations, from plain filtering to a complex washing or treatment of the particulate bed with different liquids in order to extract desired matter from the raw bed.
