Definitions

  • the present invention relates to a stirring head for mixing of liquids and pastes, and in particular dispersioncolors by means of a rotating shaft and mixing wings secured to the latter.
  • a mixing device which comprises a shaft rotating vertically and coaxially in a container and which has at least two propeller-like stirring wings as a rotor, which wings are disposed axially closely to each other in a mirror image arrangement relative to each other.
  • This known device has the drawback that the intensity of the mixing can be changed only by the variation of the number of revolutions of the shaft. It is, therefore, required to provide a variator or a reduction gear.
  • the crank arrangement can be formed in such manner, that the ends of the wing shafts are cranked to form cranks and project into an annular groove provided at the end of the connecting rod.
  • the crank arrangement can be disposed in a hollow flange member open on one side, which is secured to the end of the shaft and two flanges extending crosswise to the shaft can be provided at the open end of the flange member, the wing shafts being swingably mounted between the flanges.
  • the mixing wings can be formed rectangularly and riveted to the wing shafts upon mounting of the mixing wings on the wing shafts.
  • FIGURE 1 is an elevation of the stirring head
  • FIG. 2 is a vertical section along the lines 2-2 of FIG. 3;
  • FIG. 3 is a horizontal section along the lines 33 of FIG. 2.
  • the stirring head comprises a shaft 1, the lower end of which is immersed, preferably, vertically into the liquid to be mixed.
  • a flange member 2 is secured to the lower United States Patent 0 end of the shaft 1 and in particular, is screwed to a thread 4 of the latter.
  • the flange member 2 is open at its bottom and surrounds bell-like a hollow chamber 3.
  • the shaft 1 has an inner bore 5.
  • a connecting rod 6 is axially movable in the inner bore 5 of the shaft 1.
  • An upper annular flange member 7 is welded at the point indicated by 9 to the lower free end of the flange member 2.
  • Screw bolts 10 extend through the upper annular flange 7, which screw bolts 10' secure a lower, annular flange member 8 to the flange member 7.
  • Four bores 10 extend crosswise to the longitudinal axis of the shaft -1 at the joining faces of the flange members 7 and 8, which bores 10 are disposed at an angle of apart from each other.
  • Wing shafts 12 are swingably mounted in the bores 10. Each wing shaft 12 projects outwardly with a section from the corresponding bore 10. Mixing wings 13 having a bore 15 are mounted on the projecting ends of the respective wing shafts 12. Each mixing wing 13 is, preferably, of rectangular shape. The mixing wings 13 are disposed horizontally in the median position of the connecting rod 6 on the wing shafts 12 and in this position they are secured to the wing shafts 12 against rotation by rivets 14. The wing shafts 12 are secured against axial movement within each bore 10 by means of a pin 17 extending into an annular groove 16 within each bore 10 of the flange members 7 and 8.
  • the inner ends of the wing shafts 12 extend into the hollow chamber 3, which is surrounded by the flange member 2 and the wing shafts 12 are cranked within the hollow chamber 3 to form cranks 18.
  • the lower end of the connecting rod 6 projects into the hollow chamber 3 such, that its lower edge is disposed in its methan position at about the level of the bottom side of the flange member 8.
  • the lower end of the connecting rod 6 is equipped with an outer thread 19.
  • a disc 20 is screwed to the thread 19 of the connecting'rod 6, the peripheral face of the disc 20 having an annular groove 21.
  • the cranks 18 of the wing shafts 12 extend into the annular groove 21 of the disc 20 such, that they are subjected to a swinging movement upon axial displacement of the connecting rod 6.
  • the stirring head is shown in its median position, in which the mixing wings 13 are disposed horizontally. If, for instance, dispersion-colors are to be mixed together, the stirring head is immersed into the liquid colors.
  • the shaft 1 is subjected to rotation by any conventional means (not shown).
  • the position of the mixing wings 13 is varied by means of displacement of the connecting rod 6.
  • the connecting rod 6 can be moved within the shaft 1 from the median position, shown in full lines in FIG. 2, into an upper position 22, shown in dotted lines, on into a lower position 23, shown likewise in dotted lines.
  • the ends of the crank arms 18, disposed in the annular groove 21, are moved, thereby, due to the movement of the disc 20 together with the connecting rod 6, whereby the wing shafts 12 and the mixing wings 13 swing about their substantially horizontal axes.
  • the mixing wings 13 can, thus, be turned towards the right or towards the left. Due to the variation of the rising angle of the mixing wings 13, the mixing intensity is varied. In view of the possibility of swipging of the mixing wings 13 in both directions, the liquid to be mixed can be stirred either from above to below or from below to above.
  • the adjustment of the mixing wings 13 can be obtained during the stirring procedure also by any conventional hydraulic means.
  • said wing shafts being swingably mounted between said 1.
  • the stirring head as set forth in claim 1, which insaid shaft being a hollow shaft, and 10 eludes said means permitting swinging of said mixing wings a disk secured to the lower end of said connecting rod comprises a connecting rod axially movable in said and having said outer annular groove, and hollow shaft, means for threadedly connecting said disk to said cona Wing shaft coordinated to and supporting the correnecting rod.
