Definitions

  • the invention relates to a seal for a dynamic mixer.
  • a dynamic mixer is used in particular when mixing a plurality of viscous or pasty components, such as impression compounds in the dental field, two-component adhesives or sealants.
  • a dynamic mixer for mixing components with different volume fractions known, in particular for the production of impression materials for dental impressions.
  • a pre-chamber is arranged, within which the mixing rotor has a distributor body for distributing the components about its axis of rotation, to thereby achieve a correct mixing ratio between the components and to avoid air pockets. Subsequently, the premixed components reach their complete mixing through at least one passage opening in a main chamber.
  • the mixer Since the components in the mixer react and harden when the discharge is interrupted, the mixer must be replaced and disposed of with the components contained therein after use. In particular, the components can get into the space between the mixing rotor and the cover of the mixer housing, precisely at the point at which the mixing rotor is mounted in the cover. For this reason, in the W02007 / 041878 a sealing lip is provided, which is arranged downstream of the bearing.
  • the object of the invention is to ensure that no filling material exits from the housing of the mixer.
  • a dynamic mixer for a plurality of fluid components which includes a housing and a rotor element, which is rotatably arranged in the housing.
  • the housing has an inlet opening for at least one component and at least one outlet opening.
  • annular space is provided, in which a mixing element connected to the rotor element is arranged.
  • a seal for sealing the rotor element is provided in the housing.
  • the seal comprises a first sealing element and a second sealing element, so that it can be ruled out that filling material exits from the housing.
  • the second sealing element has a cylindrical bearing surface on the rotor element, which is mounted in a cylindrical portion of the housing.
  • the first sealing element is upstream of the second sealing element and thus the second sealing element between the first sealing element and the outlet opening.
  • the first one Sealing element designed as a sealing lip.
  • the sealing surface may have a profiling. The profiling may optionally be provided on the rotor element or in the opening of the housing, which is intended for receiving the rotor element.
  • the first sealing element is arranged upstream of the second sealing element.
  • the first sealing element can be designed as a sealing lip.
  • the second sealing element may be formed as a sealing surface.
  • the sealing lip has, according to one embodiment, an inlet-side flank, a vertex and an outlet-side flank.
  • the angle which the inlet-side flank encloses with the sealing surface is smaller than the angle which the outlet-side flank encloses with the sealing surface.
  • the inner diameter of the sealing surface is greater than the minimum inner diameter of the sealing lip when the rotor element is not installed in the housing.
  • the housing comprises a first housing part and a second housing part, wherein the first housing part contains the inlet openings and the second housing part contains the outlet opening.
  • the rotor element is mounted in the first housing part.
  • the housing comprises a first prechamber and a main chamber, wherein the inlet openings open into the first prechamber.
  • a second pre-chamber may be provided for better pre-mixing between the first prechamber and the main chamber.
  • At least one opening between the rotor element and the housing for the passage of the components may be provided between the first prechamber and the second prechamber.
  • a mixing element may be arranged to further intensify the pre-mixing.
  • Equalization of the residence time is to be understood as a reduction of the deviations of the actual residence time from the residence time desired by the chemical reaction. If the sealing lip is provided upstream of the bearing point of the rotor in the first housing part, the bearing gets an additional function as a labyrinth. A possible backflow of the components from the antechamber can thus be prevented by the labyrinth. If, contrary to expectation, backflow of the components through the labyrinth nevertheless occurs, a sealing lip is provided which prevents these components from returning to the inlet channels, so that such a side stream can be prevented during the entire operating time of the mixer.
  • the mixing ratio of the first and the second component may be 1: 1, but may also be up to 1: 5, a maximum of 1:50.
