Definitions

  • the invention relates to a stirrer for rapid mixing of different viscous reactants.
  • a stirrer should be developed which allows small foam samples from 1 to 100 g, especially 1 to 32 g, e.g. to produce a maximum of 16 g with the classic produced 200 to 300 g foam samples comparable results. For this finds the Foaming process in a stirred cup instead.
  • the object of the invention is therefore to provide a stirrer which Within a few seconds of at least 2 s, in particular at least 3 s, viscous reactants with a viscosity of 0.001 Pa ⁇ s to 500 Pa ⁇ s in low-fill containers in the range of at least 1 mm, in particular of at least 3 mm, mixed.
  • the object is achieved in that at a beam stirrer the above mentioned type at the ends of the stirring bar in each case at least one helical segment with a Incident angle is provided against the shaft axis.
  • the invention relates to a bar stirrer at least comprising a shaft with a Drive means for the rotation of the shaft and a terminal mounted on the shaft Stirring bar, wherein the ends of the stirring bar are each provided with a helical segment, which is employed at an angle of 25 to 65 °, preferably 30 to 60 °, against the shaft axis.
  • spiral segments are mounted so that they have a conveying effect during rotation of the stirrer have to the mixing tank bottom.
  • the stirrer has two, in particular crosswise arranged, stirring bars with terminal spiral segments on.
  • stirrer in which the width of the helical segments up to 10% of the outer diameter of the stirrer.
  • the helical segments are mounted on the stirring bar, that they are connected in the central region of their longitudinal extent with the stirring bar. in this connection the upper half of the helical segment leads the stirring bar ahead of the lower half Stirring bar lingers in rotation.
  • the helical segments are at one attached to the stirring bar parallel mounting bar above the Rlickbalkens.
  • You can be releasably or permanently connected to the mounting bar. Besides, they can be resiliently mounted for example by means of springs on the mounting bar. Hereby becomes causes a greater stability of the stirrer design.
  • the underside of the stirring bar and / or the outside of the helical segments provided with a scraper edge of an elastomeric or thermoplastic material.
  • the Wiping edge is boden aus or wall, so that even at low level in a stirrer small amounts of the components can be homogenized.
  • Another object of the invention is a stirrer assembly comprising an inventive Mixer and a mixing container, with both the bottom of the stirring bar as well the outside of the spiral segments running wall to the inner wall of the mixing container is. Preference is given to the underside of the Rrindbalkens and the outside of the Spiral segments with a scraping edge of a thermoplastic, e.g. PTFE, PVDF, PFA, or elastomeric plastic provided.
  • a thermoplastic e.g. PTFE, PVDF, PFA, or elastomeric plastic provided.
  • the stirrer finds above all use for mixing reactive mixed material with components different viscosity in the range of 0.001 Pa.s to 500 Pa.s.
  • he has special Advantages in partially filled mixing containers and mixed / homogenized in the range of seconds few sinking customers of at least 2 s.
  • the stirrer according to FIG. 1 has a stirring bar 2, which at the lower end of the shaft 1 is attached.
  • the stirring bar 2 is broken at two points 4.
  • filament segments 3 welded, which at an angle of 45 ° to Shaft axis 1 and the stirring bar 2 are.
  • a the Rlickbalken 2 parallel mounting beam 2b is provided above the stirring bar 2.
  • the stirred tank (not shown), which together with the stirrer a stirring arrangement forms, has in the middle of its soil on a production-related raised gate.
  • a corresponding Recess 2a provided around the stirrer to the container wall.
  • the stirring bar 2 also has at its lower, the stirred tank facing a scraping edge 5 on.
  • the wall-mounted stirrer is operated at a speed of up to 3500 min -1 and conveys the components to be homogenized from the bottom to the edge zone of the stirring cup. At the same time, the components on the edge of the stirred tank are conveyed from top to bottom with the wall-mounted spiral segment 3.
  • the resulting liquid ring is homogenized with straight (or in a non-subscribed form obliquely employed) Rlickbalken 2.
  • the resulting finished foam pattern has a uniform foam structure and streak-free edge zones.
  • a typical recipe example has components with the following viscosity: Component 1 100 mg viscosity about 0.001 1 Pa ⁇ s Component 2 200 mg viscosity about 0.001 Pa ⁇ s Component 3 4900 mg viscosity about 20 Pa ⁇ s Component 4 2300 mg viscosity about 400 Pa ⁇ s Component 5 1100 mg viscosity about 0.001 Pa.s Component 6 7400 mg viscosity about 0.4 Pa.s
