Definitions

  • the present invention seeks to provide a mixing arrangement, capable of providing an emulsion of substantially regular discontinuous phase volumes, and of operating as a continuous process.
  • a mixing arrangement comprising a casing, a rotatable • assembly supported in said casing and means for rotating the rotatable assembly relative to said casing, characterised by inlet means for supplying emulsion materials to said casing, outlet means for discharging emulsion from said casing, and wherein the rotatable assembly comprises a shaft with at least one element mounted thereon for rotation therewith, said rotatable element presents major surfaces inclined to the direction of the axis of the shaft, said casing presents at least one fixed element supported by the casing, said fixed element presents major surfaces generally parallel to the major surfaces of the rotatable element and wherein the emulsion material is directed to flow radially between one major surface of said fixed element and one major face of said rotatable element.
  • each fixed element comprises an annular element
  • the outer diameter of said element is attached to the casing and the inner diameter of said element lies adjacent to, but spaced from, the said shaft.
  • each rotatable element is of annular form and has it's inner diameter regions secured with the said shaft and it's outer diameter adjacent to, but spaced from, the casing.
  • the rotatable assembly includes mixing means, in that region of the casing into which the emulsion materials are first introduced into the casing.
  • emulsion materials are continuously supplied to the casing and mixed emulsion is continuously discharged from the outlet means for the casing.
  • the method is characterised by the steps of supporting a plurality of rotatable elements on said shaft, spacing said rotatable elements apart in the axial direction of said shaft and providing a fixed element between each adjacent pair of rotatable elements whereby to cause the emulsion forming materials to pass radially between each rotatable element and the fixed elements adjacent thereto.
  • the method includes the steps of arranging apertures through the fixed elements to enable emulsion forming materials to pass axially through said apertures.
  • the method includes the steps of passing the emulsion forming material through a mixing chamber within said casing prior to allowing the emulsion forming materials to pass to the rotatable and fixed elements.
  • the method is characterised by the steps of passing the emulsion forming material through a pre-mixing arrangement before supplying said emulsion forming materials to the said casing.
  • the method includes the steps of continually passing emulsion forming material into the said casing and continually discharging formed emulsion from said casing.
  • the shaft 17 has two diametrically opposite paddle blades 21 and 22 attached to it's upper regions within the casing 10 and the paddles 21, 22 rotate within the free surfaces of three radial ribs 23, 24 and 25, only ribs 23 and 24 of which are illustrated, presented by the casing 10.
  • the conduits 14 and 15 discharge their respective materials into that region of the casing 10 swept by the paddles 21, 22.
  • the rotatable assembly comprising shaft 17, paddles 21 and 22, and rotatable elements 27, is rotated by the prime mover 20 and the two materials to form the emulsion are supplied to the upper regions of the casing 10 by the conduits 14 and 15, the said two materials being supplied to the casing 10 in the desired proportions to achieve the desired emulsion.
  • the paddles 21 and 22 With the upper regions of the casing 10 charged with the emulsion materials the paddles 21 and 22 generate flows within the two materials to generally mix the two materials together and this initial mixing is aided by the shear forces exerted by the paddles 21 and 22 as they pass the free faces of the ribs 23, 24 and 25.
  • the premixed materials flow axially through the assembly of fixed and rotating elements 26 and 27 and through the spider 19 to the conical bottom 12, from which the emulsion flows out of the mixer via the outlet duct 13.
  • the fixed and rotatable elements 26 and 27 may present uninterrupted major surfaces, whereupon the mixture of emulsion materials flowing from the chamber above the uppermost fixed element 26 flows downwardly between the shaft 17 and the inner diameter 261b of the said first fixed element 26 and therefrom the emulsion flows radially outwardly between the first fixed element 26 and the first rotatabls element 27 towards the internal wall of the casing 10. Therefrom, the emulsion flows axially, as viewed in Fig 1 , downwardly between the wall of the casing 10 and the outer diameter 27t> of the first rotatable elements 27 into the space between the first rotatable element 27 and the second fixed element 26.
  • the two ducts 14 and 15 for supplying emulsion materials to the casing 10 may be replaced by a single inlet 31 which houses a conventional static mixer 32.
  • the two emulsion materials are supplied to the upstream end of the static mixer 32, conveniently via ducts 33 and 34, and by this means a premixing of the emulsion materials is obtained before said materials are released into the casing 10.
  • the number of fixed and rotatable elements 26, 27 can be varied, the radial dimensions of the fixed and rotatable elements 26, 27 can be varied, the distance between each fixed and rotatable element 26 and 27 can be varied and apertures 27a, 27b or 27c through the fixed and/or rotatable elements can be varied but the optimum dimensions and arrangements can be readily determined from the desired volume range for the discontinuous phase materials and the desired throughput for the apparatus. Whilst the present invention has been described by way of specific embodiments the invention is not limited thereto and many modifications and variations will be apparent to persons skilled in the art.

Abstract

L'invention concerne un dispositif de mélange comprenant un carter (10), des orifices d'entrée (14, 15) pour l'alimentation des matières à mélanger dans ledit carter, des orifices de sortie (13) pour évacuer les matières mélangées dudit carter et un ensemble rotatif pour mélanger les matières dans ledit carter. Selon une version, l'ensemble rotatif est supporté de manière rotative dans le carter et il comprend un arbre (17) avec une pluralité d'éléments tournants (27) montés espacés axialement les uns des autres sur l'arbre et tournant avec lui. Le carter comporte une pluralité d'éléments fixes (26) et chaque face principale de chaque élément tournant intermédiaire fait face à la face principale de l'élément fixe individuel correspondant, tout en étant espacée. Les éléments fixes présentent leurs faces principales généralement parallèlement aux faces principales des éléments tournants et perpendiculairement à l'axe de l'arbre. Grâce à ce dispositif, les matières à mélanger sont entraînées pour s'écouler radialement et successivement entre la face principale de chaque élément fixe et la face principale de l'élément tournant correspondant et pour s'écouler vers l'orifice de sortie du carter.
