Definitions

  • the invention relates to 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 connected downstream and rigidly connected to the mixing tank, in which the building material the cylindrical mixing tank from a storage container through a substantially the same cross section as that Mixing container having recess in the container wall is supplied.
  • Devices of this type have either a vertically arranged mixing container tube (DE-OS 2 257 613 and OE-PS 331 165) or a mixing container tube arranged inclined with respect to a vertical inlet connection or with respect to a storage container with a funnel-shaped outlet with a vertical funnel axis. (DE-OS 2 420 023 and OE-PS 322 189).
  • the invention is therefore based on the object of providing a device with which dry mortar with different grain structure can be processed without the aforementioned disadvantages occurring.
  • this object is achieved in a mixing and pumping device of the aforementioned type by that the component consisting of the mixing container and the feed pump is arranged to be pivotable about an essentially horizontal axis passing through the center of the recess provided in the wall of the mixing container.
  • the component consisting of the mixing container and the feed pump in this case has a round flange which delimits the inlet opening and is mounted in an annular collar delimiting the outlet opening of the storage container.
  • the ring flange is so arranged off-center with respect to the axis of the mixing container tube that the pivot axis is above the longitudinal axis of the mixing container tube when the mixing container tube is inclined.
  • evenly inclined inclined surfaces are created in the aforementioned intermediate area with essentially the same light cross-section of the flange and the mixing container tube, which ensure proper loading of the mixing container.
  • the stock Container and the impeller conveying into the mixing container is advantageously arranged so that the axis of rotation of the impeller lies in the line of alignment of the pivot axis of the mixing container.
  • the storage container is designed as a substantially horizontally lying cylinder with a screw conveyor
  • the cylinder and the screw conveyor are arranged in such a way that their axis is aligned with the pivot axis or is located above it.
  • a feed screw 11 is arranged, with the shaft of which stirring elements 12 are connected in the lower part of the mixing container.
  • a connecting piece 13 connected to a water pipe is provided on the mixing container tube.
  • annular flange 14 is attached to the mixing vessel jacket, which is somewhat bulged at this point, opposite the water inlet connection 13.
  • a screw pump 2 with outlet 3 which is aligned with the shaft of the feed screw and is driven by the motor 4 via this.
  • 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 tube 1, on the wall part 51 facing the mixing container 1, a partial annular collar 52 is arranged, which serves the ring flange 14 as a rotary bearing.
  • the bottom of the storage container 5 passes through a PTO 54 driven by a motor 53, 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 to be fixed in a desired inclined position. In this position, the container can be fixed by means of clamping members which engage the ring flange or 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 container 1 or through the storage container 5.
  • the easy adjustability of the mixing container tube enables the user to pivot the tube during the operation of the mixing pump, for example if material with coarser grain is conveyed from the storage container.
  • the pivotable arrangement of the mixing container tube also has the further advantage that the device can be connected from case to case with screw pumps of different lengths or multi-stage pumps in order to generate a higher pressure in this way, which may be necessary, for example, when plastering external facades .
  • the bearing flange can also be arranged in a position other than that shown in the drawing, with the interposition of a curved connecting piece attached to the storage container, so that the mixing container tube can also be pivoted about other axes.
