Definitions

  • the invention relates to an improvement in a device for the continuous mixing of powdery or fine-grained building materials with water and for conveying the mixture by means of a pump which is connected downstream of a mixing container which can be pivoted relative to a storage container and is rigidly connected to the latter, the building material separating the cylindrical mixing container from the Storage container can be fed through a recess in the wall of the storage container having essentially the same cross section as the mixing container.
  • Devices of this type either have, e.g. the device according to DE-OS 2 257 613, a vertically arranged mixing container tube, which can be pivoted from a locked position about a vertical axis from the storage container for cleaning purposes, or, e.g. the device according to DE-OS 24 20 023, a mixing container tube, which is attached to a vertical inlet connection or to a storage container with an outlet formed by a vertical funnel in an inclined position to the horizontal.
  • Gypsum-based dry mortar often leads to malfunctions due to its very fine-grained base. These are due to the fact that the fine-grained material attaches to the shaft of the screw conveyor arranged in the upper part of the mixing container and thus prevents uniform metering and sufficiently effective ventilation. The result of this is that the mix from the feed pump has a changing consistency or comes out intermittently due to trapped air bubbles.
  • the invention is therefore based on the object to improve a mixing and conveying device of the type mentioned in such a way that dry mortar with different grain structure can be processed without problems.
  • the mixing container can easily be pivoted into the position most favorable for the grain size during operation of the pump, for example if material with coarser grain is conveyed from the storage container.
  • the pivoting arrangement of the mixing container also has the further advantage that pumps of different lengths or multi-stage pumps can be connected to the device from case to case in order to generate a higher pressure in this way, which may be necessary, for example, when plastering external facades .
  • the component consisting of the mixing container and feed pump can be stored in such a way that the mixing container has an annular flange which delimits the inlet opening and is mounted in a half-ring collar delimiting the outlet opening of the storage container.
  • the advantage of a swivel bearing, in which the ring flange is only encompassed by a half ring, consists in a simpler and quicker disassembly, which has an advantageous effect both when cleaning and when transporting the device.
  • the arrangement of the ring flange such that it - seen in the direction of the mixing container pivot axis - comprises the eccentric end of an obliquely upward lateral connection of the mixing container relative to the longitudinal axis of the mixing container has the advantage that the introduction of the dry material from the storage container is facilitated and that in the case of an inclined mixing container, deposits are avoided in the area between the ring flange and the inner wall of the mixing container and a uniform loading of the mixing container with dry material is ensured. If the cross section of the flange and the mixing container arranged on the connecting piece is of substantially the same size, evenly inclined inclined surfaces are created in the area between the flange and the circular cross section of the mixing container located under the connecting piece, which ensure that the mixing container is loaded correctly. With such a design of the nozzle, the pivot axis offset from the longitudinal axis of the mixing container lies above the longitudinal axis of the mixing container.
  • a vertical circular cylindrical container is used as the storage container, it is advantageously arranged such that the pivot axis of the mixing container intersects the shaft which forms the vertical axis of the circular cylindrical storage container and is equipped with radially arranged conveyor vanes.
  • the storage container is designed as a substantially horizontally lying cylinder having a screw conveyor
  • the storage container and screw conveyor are arranged in such a way that their axis is aligned with the pivot axis of the mixing container or is also located above it.
  • a feed screw 11 is arranged, with the shaft in the lower part of the mixing container 1 mixing tools GE 12 are connected.
  • the mixing container 1 has a connecting piece 13 connected to a water pipe.
  • an annular flange 14 is attached to a lateral connection of the container shell opposite the connection 13 at the mixing container jacket which is somewhat bulged at this point.
  • the mixing container 1 is followed by a screw pump 2 with outlet 3, which is aligned with the shaft of the feeder screw 11 and driven by the motor 4.
  • the storage container 5 On the side of the ring flange 14, the storage container 5 is arranged on the side of the mixing container 1, on the wall part 51 facing the mixing container 1 a half-ring collar 52 is arranged, which serves as a rotary bearing for the ring flange 14.
  • the bottom of the storage container 5 passes through one of. a motor 53 driven shaft 54 onto which an impeller with blades 55 in the form of blades is wedged.
  • the storage container 5 rests on a mobile frame 6.
  • teeth are provided on the edge of the ring flange which, in cooperation with a pawl, enable the mixing container 1 to be fixed in a desired inclined position. In this position, the mixing container 1 can be fixed by means of clamping devices acting on the ring flange 14 or also by means of screws.
  • the drying of the dry material takes place in a known manner along the shaft of the feed screw 11 through ventilation openings provided at the upper end of the mixing container 1 or through the storage container 5.
