Definitions

  • the invention is based on a Conching tool or mixing tools, fastened to a shaft which is rotatably mounted in a drum, the mixing tools ending at a short distance from an inner surface of the drum and the shaft having drive means.
  • Mixing tools of this type have been known for decades and are used in largely horizontally aligned drums in order to mix bulk goods and liquid masses of any kind.
  • the mixing tools are fastened on a shaft which is rotatably mounted in the drum.
  • particular attention must be paid to the installation position of the mixing tools in relation to the inner wall of the drum, provided that the mixing tools are to end at a short distance from the inner wall of the drum. Deformation of the material can result in the centrifugal unit being blocked in the drum if the centrifugal unit (shaft and mixing tools) is not properly designed and assigned to the drum.
  • Such a very simple measure can be used to performance mixing devices are therefore not suitable because such a measure usually favors undesired product deposits on the inside of the drum and also creates free spaces which cannot be actively used to the desired extent during a mixing process for product treatment.
  • the mixer of DE 28 02 876 C2 uses a mixture of lighter and heavier particles. By adjusting the mixing tools and arranging the side flanks, the axial conveying effect of the mixing tools becomes larger or smaller. However, this conveying effect cannot be achieved with the mixing tools shown in the figure of DE 28 02 876 C2, which open in the circumferential direction, because between the inner drum wall and mixing tools, mixed material would bring the mixing process to a standstill. DE 28 02 876 C2 does not contain a reason for the special inclination shown.
  • DE 35 23 060 AI relates to the construction of the mixing tools to US 3,027,102, where the outer sides of the mixing tools are curved in accordance with the mixing drum.
  • the mixing device of DE 35 23 060 A1 designed in this way, a mixture is to be brought into a comminutable state relatively quickly, the original mixture being able to consist of dry powders or other particles which are used only later to form a slurry of liquid is added.
  • This originally dry mixture would, however, in the case of the mixing tools of DE 35 23 060 A1 (FIGS. 2 and 3), which are inclined and deviate from US Pat stop here.
  • the object of the present invention is to improve a mixing tool, such as a known ploughshare shovel, in such a way that, in addition to the mixing process, material restructuring in the product to be conched is also favored.
  • this object is achieved in that the mixing tool or tools, viewed in the direction of rotation of the mixing tools, further away from the drum interior in the front region. Surface are spaced apart than in the rear area.
  • the arrangement according to the invention from the mixing tool to the inner wall of the drum has the advantage that the product to be conched between the mixing tool and the inner surface of the drum is exposed to a pressure during one revolution of the mixing tool, which causes a change in the product in the individual grain or in individual volume areas of masses.
  • the "melt" can thus be influenced in a defined manner.
  • the aroma of such a mass can be influenced.
  • the product configuration can be influenced in a targeted manner by such a measure, in that such a product after treatment in the arrangement according to the invention, e.g. has a changed flow behavior, a changed particle surface structure, a changed aroma or a changed color.
  • product structuring which cannot be achieved economically or reproducibly with a mill or press, can be achieved in a mixing process.
  • An essential part of the invention is that due to the angle or angles of the mixing elements to the drum interior wall product restructuring in the treatment of masses in the mixer, dryer, granulator and / or reactor are provoked. It is of crucial importance that during the treatment the product to be conched is exposed to flat pressure in the end area of a mixing tool. The force acting on the product to be conched increases from the tip area of the mixing tool to the end area.
  • the mixing tool or tools have concave or convex side walls which end in the front region tapering to a point and widen in the rear region, and the two side walls are at a direct distance from the inside surface of the drum via a bottom wall which is largely adapted to the rounding of the drum connected to one another in such a way that the side walls are connected to one another by the bottom wall without any steps, restructuring of the product is strongly supported because such mixing tools have a good specific mixing performance.
  • the product in the gap between the mixing tool and the inner surface of the drum is frequently replaced, so that a homogeneous and uniform treatment of the entire product in the drum is ensured.
  • the side surfaces in such mixing tools end, starting from the bottom wall, directed radially inwards into the drum space in a section line of the side surfaces.
  • It is a mixing body which is formed, for example, as a hollow body from two side surfaces, a bottom wall and a rear wall.
  • the mixing arm opposite the bottom wall connects to this mixing body.
  • the mixing body and the mixing arm form the mixing tool.
  • the individual Mixing tools are arranged on the shaft in such a way that the individual bottom walls sweep the entire inner surface of the drum when the shaft rotates 360 °.
  • the mixing tool or tools in the interior of the drum are designed as full mixing tools symmetrical to an axis. This has the advantage that, in the event of displacement movements in the bulk material or in the masses to be treated, the product distribution in the mixing area is divided into the same product parts. This enables high mixing qualities to be achieved.
  • half-mixing tools are arranged on a shaft in the drum. These half-mixing tools are assigned to end walls which limit the drum on both sides. The half-mixing tools are spaced further apart from the inside surface of the end wall in the front area than in the rear area. Lateral pressing processes can also be generated via the half-mixing tools, which also promote restructuring processes in the product.
  • the bottom wall (s) of the mixing tools can have an additional material coating. This can prevent excessive material abrasion during a mixing and restructuring process.
  • the side surfaces which lie directly opposite the end walls of the drum are matched to the contours of the inside walls of the end wall and the side surfaces of the half-mixing tools are concave or convex, pointing into the inner region of the drum.
  • the half-mixing tools are thus largely approximated in their function to the full-mixing tools.
  • Fig. 1 shows an arrangement according to the invention
  • Fig. 2 shows an arrangement according to the invention by a
  • FIG. 3 shows a full mixing tool according to the invention in a three-dimensional representation
  • Fig. 4 shows a half-mixing tool according to the invention in a three-dimensional representation.
  • FIG. 1 shows a side view and in section of a mixing tool 10 as it is fastened on a shaft 11 and how the shaft 11 with the mixing tool 10 is arranged in a drum 12.
  • Several mixing tools 10 on the shaft 11 form a centrifugal machine.
  • the direction of rotation of the centrifugal mechanism is indicated by arrow direction 13.
  • the mixing tool 10 is composed of a mixing body 14 and a mixing arm 15.
  • the mixing arm 15 is either releasably attached to the shaft (screw connection in pocket) or the mixing arm 15 is welded to the shaft 11.
  • the mixing body 14 shown in side view has a tip 16 in the direction of rotation of the centrifugal mechanism in the direction of arrow 13 and the rear end of the mixing body 14 is formed by a rear wall 17.
  • the mixing body 14 in the front area 19 is spaced further apart from an inner drum surface 18 than in the rear area 20. If a product to be mixed and restructured gets into the gap between the mixing body 14 and the inner drum surface 18, the product becomes with a rotating centrifugal unit pressed against the drum inner surface 18 to generate interparticular frictional energy.
  • 2 shows a top view around the section of a drum 12 with an end wall 21 and an inner region 22.
  • a full mixing tool 23 and a half mixing tool 24 are arranged on the shaft.
  • Mixing tools 10 mean both full mixing tools 23 and half mixing tools _24.
  • the spacing of the full mixing tool 23 from the half-mixing tool 24 does not correspond to the actual arrangement of these tools on the shaft 11.
  • the mixing tools 23, 24 are always offset in the initial direction. The actual arrangement of the mixing tools 23, 24 seen over the circumference of the shaft 11 cannot be seen in FIG. 2.
  • the full mixing tool 23, a ploughshare blade, is composed of a side surface 26 and a side surface 27.
  • the two side surfaces 26, 27 are connected to one another via a bottom wall 28.
  • the bottom wall 28 is smooth and modeled on the contour of the drum inner surface 18.
  • the transition area from the bottom wall 28 to the side walls 26, 27 is smooth and has no heels.
  • the side walls 26 and 27 run in the tip in the direction of rotation of the shaft 11
  • the full mixing tool 23 is connected to the shaft 11 via the mixing arm 15.
  • the side walls 26, 27 have a concave configuration in FIG. 2, as is usual with ploughshare displays.
  • the full mixing tool 23 is spaced further apart from the drum inner surface 18 in the area of the tip 16 than in the area of the rear wall 17.
  • the width of the full mixing tool 23 in the area of the rear wall 17 results from the specification of how large the interparticular frictional energy generated in the product to be processed should, should be.
  • the half-mixing tool 24 is composed of a concave side wall 29, a rear wall 30, a bottom wall 31 and a side wall 32 which is based on the contour of the front wall 21.
  • the side wall 29, the rear wall 30, the bottom wall 31 and the side wall 32 together form a hollow body which is fastened to the shaft 11 via a mixing arm 33.
  • the side wall 29, the rear wall 30 and the bottom wall 31 form a tip 32 'in the direction of rotation of the shaft 11.
  • the direction of rotation of the shaft 11 is indicated by arrow 34 in FIG. 2.
  • the semi-mixing tool 24 is further away from the inner surface of the end wall 21 than in the rear side area 36. If the product to be processed reaches the gap between the half-mixing tool 24 and the inner surface of the end wall 21, the product to be treated becomes interparticulate friction energy generated.
  • FIG. 3 shows a perspective view of a full mixing tool 23, as shown in different views in FIGS. 1 and 2.
  • the full mixing tool 23 is formed from curved and concave side walls 26 and 27 which merge with the rear wall 17 into the mixing arm 15. In the area from the tip 16 to the mixing arm 15, the full mixing tool 23 ends in the cutting line of the side walls 26, 27.
  • the side walls 26, 27 widen towards the rear wall 17 and are over the bottom wall 28 connected to each other.
