Definitions

  • ABSTRACT Emulsifying and dispersing apparatus having at least one working stage formed of at least two concentric tool rings rotating relative to one another, such as a rotor and a stator, the tool rings including toothed elements separated by groove spaces which cooperate at least partly with a shearing action, are arranged about a suction chamber serving as a central supply chamber.
  • At least one of the tool rings preferably runs at a frequency which may be as high as high ultrasonic values.
  • Parallel surfaces of adjacent toothed elements, which bound the groove spaces in the peripheral direction of one of the tool rings have portions that are disposed in the axial direction at an acute angle relative to the surfaces or planes of the toothed elements of the other tool ring.
  • adjacent toothed elements constitute with their respective groove space cooperating impacting and shearing flanks tween the two rings, while the groove spaces in the outer tool ring constitute discharge openings about the entire periphery of the apparatus.
  • the invention relates to an emulsifying and dispersing apparatus for the treatment of a medium.
  • Apparatus for producing emulsions and dispersions for laboratory work and general production are already known which are based on the principle ofa processing head rotating in the medium, e.g. a liquid mixture or liquid-solid mixture,.
  • Preferred apparatus of this kind comprise a rotor adapted to rotate relatively to a stator,
  • a slotted rotor tube rotates in a likewise slotted stator tube.
  • the groove spaces provided between the toothed elements of the stator and rotor, or the surfaces bounding said spaces are arranged parallel to one another in the axial direction, that is to say the direction of the axis of rotation.
  • the medium under pressure which is to be emulsified or dispersed is suddenly transferred over the full groove space crosssection out of the rotor groove spaces which extend in the axial direction into the likewise axially arranged outlet groove spaces of the stator.
  • Fiber materials, macromolecular cross-linked structures (polymerization products) and bio-structures are not cut with knife action" but are smashed, mainly at the edges of the toothed elements.
  • the present invention has as its object to obviate the aforesaid disadvantages, and to provide an apparatus of the type initially specified in such a manner that the risk of the formation of funnels in the medium, and therefore'of drawing in air, is reduced. At the same time the circulating effect and therefore the dispersing effect are improved to a significant extent.
  • parallel surfaces of adjoining toothed elements, bounding the groove spaces in the peripheral direction of at least one tool ring have portions that are inclined in the axial direction at an acute angle relative to the surfaces of the toothed elements of the other tool ring.
  • Fiber and structure substances are no longer crushed at the toothed element edges but are severed or sheared at a cutting angle or flank. There is a reduction in the wear which occurs on the tooth edges and there is less jamming since the amount of force expended is substantially smaller when cutting is used.
  • the apparatus can now be arranged a short distance below the surface of the medium (upper ends of the groove spaces of the stator just below the medium surface), since the construction according to the invention makes a detachment of the circulating flow much more difficult.
  • the acute angle and thus the inclination of one set of groove spaces relative to the other set amounts to about 6 to 10.
  • the groove spaces of one tool ring are bound by axially parallel or axially disposed ones of the inclined portions of the toothed elements, and the groove spaces of the other ring of the same working stage are bound by other inclined toothed element portions, the inclination being always relative to the axis of the concentric tool rings.
  • the groove spaces of the tool rings of a working stage may be arranged at an inclination in opposite directions to one another by a certain angle relative to the axial direction.
  • FIG. 1 shows a somewhat schematic view from below of a working stage formed of a rotor and a stator in an emulsifying and dispersing apparatus
  • FIG. 2 shows in development rings of tools of the conventional type, cooperating in a working stage
  • FIG. 3 shows a schematic section through the tool rings of the conventional type
  • FIG. 4 shows a development (similar to FIG. 2) of tool rings of the type provided by the present invention, cooperating in a working stage;
  • FIG. 5 shows schematically, in a sectional view (simi- .lar to FIG. 3) tool rings according to the invention.
  • a working stage of an emulsifying and dispersing apparatus comprises an outer tool ring 1 of a stator 2 (see FIGS. 3, 5) and an inner, rotating tool ring 3 of a rotor 4 arranged concentrically thereto.
  • the ring 1 is formed of toothed elements 5 which are usually separated from one another by substantially axially parallel prismatic groove spaces 6. correspondingly toothed elements 7 of the rotor ring 3 are separated by groove spaces 8. It is possible to have both rings rotate.
  • the rotor ring 3 encloses a suction chamber 9 serving as a central supply chamber.
  • a suction chamber 9 serving as a central supply chamber.
  • the medium to be dispersed or emulsified is aspirated through the suction chamber 9 and delivered to the exterior through the groove spaces 6, 8 between the toothed elements 5, 7 which cooperate at frequencies which can go up to high ultransonic or supersonic values.
  • FIGS. 2, 4 show the overlapping of the toothed elements 5, 7 and groove spaces 6, 8 of the tool rings 1, 3 of the stator 2 and the rotor 4 in a chance rotation position relatively to one another.
  • FIG. 2 the conventional or prior-art arrangement, shows that about half of all the groove spaces of the rotor or stator respectively are masked by toothed elements of the other tool ring, that is to say the stator or rotor.
  • FIG. 3 shows that the conventional prismatic form of the groove spaces 6, 8 between the toothed elements 5, 7 provides a considerable obstacle to the flow of the medium.
  • the direction of the rotation of the rotor is indicated in FIG. 4 by an arrow 11. Taking this direction of rotation into account, the inclination of the groove spaces 6 of the stator is such that the free cross-sections of passage at this particular time, formed by the overlapping groove spaces 6, 8, move apparently from below, relative to a suction aperture 10 as shown in FIG. 5, up-
  • base surfaces or portions l2, 13 of the groove spaces 6, 8 are sloped at an angle of preferably It is of secondary importance that, as shown in FIGS. 4, 5, the toothed elements 5 of at least the rotor may be connected at their free ends by a web 14 so that the groove spaces 6 are not open below but are actually inclined slots.
  • the present arrangement according to the invention can be used both in the case of conventional apparatus wherein the tool rings on the rotor and the stator extend substantially in a cylindrical arrangement and wherein the spacing between the rotor element relative to those of the stator cannot be varied, and also in the case of apparatus wherein the spacing gap between the toothed elements of both the rotor and the stator is capable of being varied in a manner as described in a US. Pat. application of one of the present joint inventors, M. Zipperer, Ser. No. 278,431, titled Emulsifying and Dispersing Apparatus, now abandoned.
  • An emulsifying and dispersing apparatus for the treatment of a medium comprising at least one working stage formed of at least two relatively rotatable tool rings having concentric axes, such as a rotor and a stator, including first and second tool rings, formed by respective first and second toothed elements in respective planes, separated by first and second, substantially parallel groove spaces, said rings being arranged about a suction chamber that serves as a central supply chamber, wherein substantially parallel portions of adjacent ones of said toothed elements, which bound said groove spaces in the peripheral direction of at least one of said tool rings and cooperate in one of said working stages, are inclined in the axial direction at an acute angle relative to the respective planes of said toothed elements of the other one of said tool rings, thereby constituting a high proportion of overlapping between said first and said second groove spaces during the rotation of at least one of said tool rings, wherein said adjacent toothed elements constitute cooperating impacting and shearing flanks between said tool rings, and
  • said groove spaces in the outer one of said tool rings constitute discharge openings about the entire periphery of the apparatus.
  • base surfaces of said groove spaces slope outwardly at an angle of about 45 in the direction of flow of the medium.
