Definitions
- the invention relates to a mixing and dissolving machine with a vertical Rotating axis revolving, upward conveying mixing spiral.
- Such a machine with two interlocking screw bands is for example known from DE-23 34 789 A1 or DE-26 38 112 A1.
- mixing and dissolving machines are two intermeshing Spirals are provided, which are attached to laterally spaced axes of rotation are.
- between two and four rotating unions through the lid or bottom of the container be provided in which the coils are provided.
- This container also has yet another elaborate double construction with an essentially 8-shaped one Cross-section. This design enables intensive mixing by relatively small portions of mix from one coil to the other be shoveled, but the structure is quite complicated.
- the object of the present invention is therefore to provide a corresponding mixing and Specify disintegration machine, in which a simpler construction is possible at which in particular the container construction is less complicated and with which adequate mixing quality is still achieved.
- the first mentioned Mixing coil is arranged in the axial direction, a second mixing coil, wherein a transition zone extends between the mixing coils in the axial direction.
- the invention has the advantage that only one axis of rotation is required. This can be easily done with just one or a maximum of two rotary unions be stored on the intended container.
- the invention has the The advantage that although there is only one axis of rotation, it is sufficient Mixing is achieved. In particular, this is possible in a simple way Container in the form of an uncomplicated cylinder.
- the two mixing coils which are arranged axially one behind the other, which fundamentally both convey in the same axial direction upwards also different have axial flow rates, whereby an additional, in the axial direction the shear gradient increases the mixing.
- This different axial flow rate can either be achieved by the two mixing helixes have different pitch angles or else by the two mixing helixes having different helix blade widths.
- the two consecutive mixing coils have different speeds of rotation have or different directions of rotation.
- each mixing paddle can have a different Conveyor angle can be equipped in both the axial and radial directions, whereby a further improved mixing effect can be achieved.
- a further improvement in the mixing can be achieved if at least individual mixing blades one at their trailing ends in the direction of rotation have angled lifting edge through which one through the mixing blades raised portion of mix a short upward Impulse is given before this mix portion due to gravity again begins to drop, then from a trailing mixing shovel again is recorded and further mixed accordingly.
- Mixing helixes are two essentially one above the other arranged mixing blades by a to the direction of rotation, in essentially vertically extending blade carrier connected to each other.
- this Blade carrier on which, if necessary, more than two arranged one above the other Paddles can be attached, the mix can still be radial Direction accelerated or slowed down.
- At least individual mixing blades can be used on the outside also with those on the container wall Comb stowage elements. By the occurring in the area of the baffle elements Shear, the mixing effect is greatly increased.
- the baffle elements can be both closed ring elements act as well as toothed ring elements, which are mounted on the container wall are. These ring elements can either only be segment-like over the circumference be arranged of the container or circulate over its entire circumference.
- a further improvement in the mixing effect is obtained if the Mixing coils are essentially aligned with the vertical axis of rotation Shaving head is arranged with which the sinking centrally around the axis of rotation Mix material is sheared again. Also a desired radial or axial Promotion of the mix can be influenced here. Works advantageously this shaving head together with an opposing head that has a different rotational speed and / or direction.
- Figure 1 shows a mixing and dissolving machine according to the invention in the cut Side view.
- drum-like housing 1 with a cylindrical shape completed by a screwed-on cover 2 and a welded-in bottom 3 becomes.
- a feed lance 6 is shown in the example shown here, with the mixed material filled through the feed opening 4, if necessary, during liquid to be added to the mixing process can.
- a shaft 8 is guided into the housing 1 on a shaft bushing 7, whose vertical axis of rotation 9 coincides with the central axis of the housing 1.
- FIG. 3 schematically shows how the individual Mixing blades are arranged.
- a zero line is marked for this purpose in FIG. 2, from which an angle ⁇ is measured.
- a small portion of mix is taken from the first mixing scoop seized and promoted axially and radially and released again. Each subsequent mixing shovel then takes parts of these conveyed Portion and continues to convey and mix them.
- Each of the mixing blades mentioned is via a blade carrier 17, as in FIG Figure 1 can be seen with a sitting over it, slightly offset in the circumferential direction connected to another mixing blade.
- These are, as in FIG. 3, too can be recognized as mixing blades 11.2, 12.2 or 13.2 corresponding to the circumferential positions arranged at angles ⁇ of 0 °, 120 °, 240 °.
- Each of these mixing blades has at its end trailing in the direction of rotation an upwardly angled lifting edge 18. This will make a serving Mix that has been lifted from the mixing shovel with a light one Provide momentum upwards before it drops again slightly due to gravity and taken up by the subsequent mixing scoop and on again is led upwards.
- mixing blade 13.2 shown is not directly one
- the mix can also Liquid can be added to a desired viscosity of the mixed material adjust.
- a liquid supply can, however, if necessary also take place centrally through the then hollow shaft 8, or also from below, which is also not shown.
- Blade carriers 17 are employed in relation to the direction of rotation, by one To support mixture favorably influencing mixture transport in the radial direction.
- these blade carriers 17 are over Support arms 20 attached to the shaft 8 which on the in the direction of rotation (according to arrow 21 in FIG. 2) lying at the front a radially outwardly increasingly sloping Have front surface 22. This also makes it possible to transport the mix supported radially outwards.
- the lowest mixing blade available 11.1 is provided with a scraper 23 which extends over the bottom 3 of the housing 1 grazes and the mixed material settling there lifts.
- mix can be mixed in smaller portions are axially and radially conveyed, always a subsequent one Mixing shovel Parts of the conveyed by the previous mixing shovel Serves up the mix portion and conveys it further. This paddling very much small portions of mix achieve fast and intensive mixing.
- the baffle elements 24 are on the wall of the cylindrical housing 1 of the mixing container Damming elements 24 attached.
- the blades to be fitted to this baffle element 24 25 which, like the mixing blades described above, closely along the cylindrical Are guided container wall, form at its radially outer end with the Accumulation element 24 an additional shear gap 26, which the mixing effect for the Vertical mixer reinforced.
- One or more blades 25 can be used Combing axially arranged rings 24 over one another. Of course apart from the all-round rings, only segments of them can be used be attached.
- the baffle elements are also formed as toothed rings 26, which the Shear effect especially increased.
- the present invention thus represents an effective device to to ensure a mixture preparation working in the vertical direction, in which highest homogeneity requirements with short batch times become.
- the drive power is not severe, but only occurs locally unnecessarily increased and wear is also reduced, fragile solids are not destroyed and also no impermissibly high temperature increases exposed.
