Abstract (en)
[origin: EP0236236A1] 1. Mixing device (2) for two liquids (4, 6) having different densities, comprising a vertical tube (10), a shaft (12) able to coaxially rotate in tube (10) and successively having from bottom to top a lower helical part (14), whose helix is formed in a first direction, at least one blade (16) located in a radial plane of the shaft (12) and having an external diameter slightly smaller than the internal diameter of the tube (10), an upper helical part (18), whose helix is formed in a second direction opposite to the first, holes (20) being formed in tube (10) facing blade (16), inlets (22, 24) for the liquids (4, 6) being provided in tube (10), characterized in that the helical parts (14, 18) have at least several complete turns, so as to form an Archimedean screw and in that helical spacings of said helical parts (14, 18) differ.
