    The invention relates to a feature of the introductory part of claim 1.
    In particular, when chemically reacting components, in particular base material and hardener material of adhesives, are to be mixed in the correct proportion, mixing devices, in particular dynamic, are used.
    The invention has for its object to provide mixing devices in which a mixing element rotates in a housing, while mixing the substances to propose, which allows a thorough and homogeneous mixing of the components with accurate dosing.
    This object is achieved according to the invention with a device having the features of claim 1.
    Preferred and advantageous embodiments of the invention are the subject of the dependent claims.
    Since in the device according to the invention, the rotating mixing element in the housing of the device in the direction of its axis is adjustable, the gap between the inner surface of the housing and the outer surface of the mixing element can be changed in size. This allows the shear rate required for mixing to be adjusted. Moreover, the device of the invention acts as a proportional valve so that the amount of mixture exiting the outlet from the device can be adjusted.
    The surfaces of the mixing element and the housing facing one another and delimiting the mentioned gap may be flat or tapering conically towards the outlet opening.
    Since in the device according to the invention, in one embodiment, the rotating mixing element in the housing is axially adjustable, so among other things, a proportional flow and pressure control is »β · ι • *« ** ···· · · · * · · * M * * possible. In particular, this means that a region is provided in which the interior of the housing and the rotating mixing element are tapered conically.
    In the invention, due to the possibility of changing the size of the gap, whether it is flat or conical, it results in an adjustable but constant shear rate.
    Since, in one embodiment, in the case of the components of the invention, intermeshing, annular ribs are provided in a mixing device according to the invention, the components, if appropriate under pre-pressure, of the mixing device are processed, at least two, components for the mixing process. This is also because in the region of the ribs a subdivision of the currents of the components occurs.
    In another embodiment of the device according to the invention results because of at least one groove or groove or because of at least one rib in the discharge side region of the rotary mixing element, the possibility of cleaning by the rotating mixing element is advanced while rotating it in the direction of the outlet opening until the gap between The mixing element and housing are essentially closed (at " zero ") (that is, they are no longer present). Here are the inside of the housing and the outside, adhering to the mixing element residues of possibly hardened mixture by " scraping " away. Thus, the device according to the invention over longer periods, without special cleaning measures after disassembly of the device are required to be used.
    Further details and features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the drawing, are shown in the mixing devices in section.
    It shows
    1 shows a first embodiment of a mixing device,
    Fig. 2 shows a second embodiment of a television apparatus and apparatus
    Fig. 3 shows a third embodiment of a mixing device.
    The device 1 shown in the drawings in Fig. 1 is formed as a dynamic mixing device and consists of a housing 2 and a rotatably received in the housing 2 mixing element 3. So that the mixing element 3 can be rotated in the housing 2, it is with a drive, not shown coupled. The mixing element 3 is sealed relative to the housing 2 by a stuffing box-like seal 4.
    In the housing 2 is an opening 5 for supplying a component, in particular base material of an adhesive, and opposite to this opening 5, an opening 6 for supplying a second component, e.g. Hardener material for a curing adhesive, provided. The openings 5 and 6 are arranged offset from one another in the direction of the axis 7 of the device 1. In particular, when the components (base material / hardening material) of a two-component adhesive are to be mixed, the opening 6 for the adhesive material of the discharge opening 8 is located closer than the opening 5 for the base material.
    The components are thoroughly mixed while migrating from the openings 5,6 to the exit opening 8 of the device 1 in the desired proportion of the components charged to the device 1.
    The rotating mixing element 3 has in the region of the feed openings 5, 6 for the components a cylindrical area 9, in which the mixing element 3 outwardly in the direction of the inner surface 10 of the housing 2 projecting annular ribs 11 are provided. The annular ribs 11 may be - as shown - inserted into grooves of the mixing element 3 rings. Between the projecting from the mixing element 3 annular ribs 11 are provided from the inner surface 10 of the housing 2 inwardly projecting annular ribs 12. By the interaction of ring ribs 11 and ribs 12 results in a crushing (chopping) of the supplied components, the * Vo »J: ü] Mvsahen the same be processed. This advantageous for the mixing effect can be further enhanced by the annular ribs 11 are toothed on the outside and / or the ribs 12 inside with any tooth shape and shape of the interdental spaces. Although these annular ribs 11 and the ribs 12 are advantageous, but need not be provided.
    Based on the conveying direction (arrow 13) after the cylindrical portion 9 of the mixing element 3, this has a conical portion 14, which is in a. 15 to the outlet opening 8 also conically tapered portion 15 of the housing 2 aüfgenommen. In the conical part 14, grooves 16 or projecting ribs are provided, for example, a plurality of annular grooves 16 (or ribs) inclined to the axis, or a helical groove (or rib). Thus, the inner surface 10 of the housing 2 can be cleaned in the conical region 15, to which the rotating mixing element 7 toward the outlet opening 8 while constantly reducing the gap 18 (to "zero") between the outer surface of the conical part 14 of the mixing element 3 and the inner surface of the conical portion 15 of the housing 2 is advanced so that the conical portion 14 rubs against the inner surface 10 of the housing 2 and cleans them.
    The embodiment of the mixing device 1 according to the invention shown in FIG. 2 corresponds to the embodiment described with reference to FIG. However, the mixing device 1 of Fig. 2 has a mixing element 3, the conical part 14 is executed without a groove or rib, that is substantially smooth.
    In the mixing device 1 shown in FIG. 3, the mixing element 3 ends with a flat (circular) end face 20, which faces the outlet opening 8. The end face 20 is limited together with the outlet opening 8 surrounding annular surface 21, the flat gap 18, the width of which can be adjusted by adjusting the mixing element 3 in the axial direction (arrow 17).
    Although neither annular ribs 11 nor ribs 12 are provided in the cylindrical cylindrical section 3 in the embodiment shown in FIG. 3, such annular ribs 11 and ribs 12 can be used as in the embodiments of FIGS 2, be provided.
    In the embodiment of a mixing device 1 shown in FIG. 3, the end face 20 of the mixing element 3 is smooth. However, it is contemplated to provide on the end face 20 rib-like projections or in the end face 20 grooves or grooves to the above-mentioned cleaning effect. to achieve.
    The device 1 according to the invention, the components in the
    Example base material and hardener material, submitted under pre-pressure, so that they are promoted by the device 1.
    The axial adjustability of the mixing element 3 relative to the housing 2 (in the axial direction) also serves to dose the amount of the mixed material emerging from the outlet opening 8 in the manner of a proportional valve.
    The device according to the invention has the advantage in the embodiments shown in the drawing figures 1 to 3 that it ensures a constant shear gradient over the conveying path of the components from the feed opening (p, 6) to the outlet opening 8. This shear gradient can be adjusted by adjusting the mixing element 3 relative to the housing 2 and thus by changing the gap 18 are set to the best value for the respective mixing process and the properties of the components to be mixed.
    In addition, a proportional quantity and pressure control is possible by the axial adjustability of the rotating mixing element 3.
    Finally, it is possible for the device 1 according to the invention to be cleaned by axial displacement of the rotating mixing element 3 in such a way that its conical region 10 is in contact with the conical part 15 of the housing 2 of the device 1.
    In summary, an embodiment of the invention can be described as follows:
