Title:
METHOD FOR MIXING LUMP MATERIALS IN A LIQUID AND DEVICE FOR REALISING THE SAME
Document Type and Number:
WIPO Patent Application WO/1999/062317
Kind Code:
A2
Abstract:
The present invention pertains to the field of counter-current mass-exchange processes that provide a continuous interaction between a solid phase and a liquid phase, for example during washing, lixiviation and dissolution processes. This invention can be used in the radio-chemical industry, in the chemical industry, in hydro-metallurgy as well as in other industrial fields. The purpose of this invention is to increase the efficiency of counter-current mass-exchange processes in solid-liquid systems, wherein said invention essentially relates to a new method as well as to a device for mixing a solid-phase lump material. The device of the present invention comprises a tubular body (1) which is inclined at an angle of between 5 and 60° relative to a horizontal surface and which comprises a packing (4) in the form of nozzles (6) defined by flat vanes (5). The vanes are inclined at an acute angle of between 5 and 45° relative to the axis of the tubular body (1), and are separated by protection grids (7) for preventing any downfall of solid-phase materials under the packing. The packing is arranged in the body along the axis thereof, divides said body into an upper chamber (2) and a lower chamber (3), and opens onto transverse partitions (11) that define cavities under the packing. The cavities communicate through ducts (13) provided in the lower area. Each cavity includes a separate pulse chamber (14), wherein the number of said chambers is an even number.
