Definitions

  • the invention relates to a mixer for producing pumpable Plastering compounds, in particular interior plaster, from dry matter and mixing water in a mixing tube that is a mixing spiral on a mixing shaft that encloses a driver for the screw of a screw pump arranged downstream of the mixing tube ends.
  • Such a mixer for example, is not published in the German patent application 197 57 734.2 known, but has the disadvantage that it, especially in the manufacture of plaster-based interior plaster, not the plaster sufficiently homogenized so that in the ready to use Mass lumps remain, which is the smoothing of the plaster complicate and to superficial during the setting Deepen, wherever lumps not sufficiently moist under the surface Material.
  • the invention has for its object the mixer to improve the genre mentioned in this regard.
  • the storage ring causes the dry matter and mixing water existing mass is redirected, which inevitably an additional mixing of the screw pump to be fed Cleaning compound causes, so that the cleaning compound the mixer homogeneously mixed in a uniform, lump-free, creamy consistency.
  • the storage ring non-rotatably connected to the mixing shaft (claim 2).
  • a conventional mixer can be replaced easily the mixing shaft, without other conversions, into one Mixer can be converted according to the invention.
  • the storage ring but can also be attached to the inner wall of the mixing tube be so that the mixing shaft rotates in the ring.
  • the retaining ring is preferably arranged in the area of the driver (Claim 3).
  • the homogenization of the plaster then takes place immediately before entering the Screw pump and the suction of the screw pump can support the homogenization by means of the accumulation.
  • the diameter of the storage ring is advantageously smaller than that Inner diameter of the mixing tube (claim 4).
  • the plaster is then through an annular gap between the baffle ring and the mixing tube wall into the suction zone of the screw pump pressed.
  • the retaining ring is advantageously distributed in the circumferential direction arranged blade plates, the degree of homogenization increase the amount of plaster (claim 5).
  • the blade plates can be on the top and bottom of the storage ring can be arranged (claim 6). Thereby can be a particularly good homogenization of the plaster to reach.
  • Each of the blade plates advantageously closes with one axial plane passing through the axis of the mixing shaft Angle of attack (claim 7). This measure will the plaster inevitably outwards, i.e. in the direction Mixing tube wall and annular gap, centrifuged.
  • the angle of attack can be between 30 and 70 °.
  • the outer edges of the blade plates hurry their inner wheels, based on the direction of rotation of the mixing shaft, according to (claim 8th).
  • the storage ring is according to a preferred embodiment arranged below the driver wedge of the driver and has a passage of the driven end of the shaft of the downstream screw allowing inner diameter (Claim 9).
  • the mixer shown in Fig. 1 for producing pumpable Plastering compounds from dry matter and mixing water consists of essentially from a mixing tube 1 which has a mixing spiral 11 encloses on a mixing shaft 12, one of the mixing tube 1 downstream screw pump 2 with a screw 21, and a drive motor 3, the mixing shaft 12 and at the same time via a driver 13 of the mixing shaft 12 also Screw 21 drives the screw pump 2.
  • the mixing tube 1 has a hopper 14 for supplying dry matter and one Connection piece 15 for the supply of mixing water.
  • the connecting piece 15 is located downstream of the mouth of the Funnel 14
  • the screw pump 2 has a steel jacket 22 and is like also known, inside with a screw 21 surrounding it Jacket 23 lined from an elastomer.
  • the worm 21 tumbles in the worm pump, at a speed of a few 100 rpm.
  • the homogenizing ring 16 consists of a Stauring 161 in on the top and bottom Blade plates 162 distributed around the circumferential direction wearing.
  • the blade plates 162 close with one through the Axial plane of the mixing shaft going an axial angle of about 40 °.
  • the outer edges of the blade plates 162 rush through their inner edges, based on those in Fig. 4 the direction of rotation of the mixing shaft indicated by the arrows. This inevitably leads the plaster to the outside Wall 17 of the mixing tube 1 flung and through a Annular gap 18 between the retaining ring 161 and the wall 17 in Pressed towards screw pump 2.
  • the storage ring 161 is below of the driver wedge 131 of the driver 13.
  • the Inner diameter of the storage ring 161 allows passage the driven end of the shaft of the downstream Snail 21.
  • Fig. 5 the flow behavior of the plaster is in the area of the homogenizing ring 16 shown.
  • the blade plates 162 together with the storage ring 161 cause the by means of the mixing helix (not shown in FIG. 5) pumped cleaning compound flung in the direction of the mixing tube wall 17, by a between the mixing tube wall 17 and the retaining ring 161 remaining annular gap 18 and then pressed transported in the direction of the suction zone 24 of the screw pump 2 becomes.
  • This creates centrifugal and shear forces that the in the plaster and not or not enough dissolve lumps soaked in water so that a homogeneous, the mixer in uniform, lump-free, plaster that leaves a creamy consistency.
  • the Cleaning compound is supported by the suction effect of the Worm pump 2, through the zone of the bottom of the Thrust ring 161 arranged blade plates 162 through Inlet of the screw pump 2 promoted.
