Definitions

  • the invention relates to a device according to the preamble of claim 1 and a method for operating this device.
  • Such a device is known from German patent application P 33 02 871.o.
  • the basic advantage of this known device is that it allows the production of ready-to-use mortar in a particularly simple manner by keeping the individual material components in stock in a common silo at the construction site and automatically removing them from this silo, so that the effort required to produce the ready-to-use mortar is significantly reduced and mixing errors are largely eliminated.
  • the individual components are metered volumetrically, which enables sufficient metering accuracy for many practical applications.
  • the invention is based on the object, while maintaining and further improving the ease of use and the general advantages of a conventional device of this type, in such a way that an even more precise metering is possible.
  • the characterizing part of claim 1 By means of the screw conveyors provided thereafter, arranged immediately below the container having a vertical division and the downstream scales, it is possible to install a ready-to-operate system on a construction site in a very short time, which mortar one can deliver exactly the specified composition. Because of the configuration according to the invention, the material storage container, the metering device and the mixing device form one unit, i.e. seized by a crane vehicle or the like by means of a single hook attachment and loaded and unloaded. Immediately after the device has been set down at the construction site, it is ready for operation, the screw conveyors ensuring reliable forced removal of the individual material components and - in connection with the scales, an exact dosage.
  • the invention is further developed according to claim 2, whereby pivoting of the screw conveyors and a mechanism required for this is unnecessary.
  • the design of the scale according to claim 3 ensures a high level of operational reliability even under harsh operating conditions, such as those found on construction sites.
  • the force transducer provided according to claim 4 enables a simple conversion of the mechanical deflection of the balance into an electrical signal, which can be further processed to control the device.
  • the mixing device is fully integrated into the metering device, which saves space and increases the operating speed of the device.
  • the water supply according to claim 8 enables an equally simple and exact water metering to the free-flowing mixing components.
  • the design of the outlet opening according to claim 9 prevents that from the mixing area of the container, soaked mixture is thrown upwards and in this way the conveying area of the screw conveyors becomes clogged.
  • a computer and control device as provided in claim 10, enables e.g. Use a pre-programmed dosage to produce mortar with the desired composition and consistency by simply pressing a button.
  • the construction according to claim 12 makes it possible to comfortably fill the container lying down, that is to say also in the transport position on a vehicle.
  • removal and dosing device can be detached from the container makes it possible to deliver a second container to a construction site with the initial delivery, the removal and dosing device being able to be easily implemented after the first container has been emptied to the second container.
  • the further embodiment of the method according to claim 15 enables premixing already during metering, so that larger material inhomogeneities are avoided from the outset.
  • a device according to the invention shown in the drawing comprises a silo-like storage container 1, which in the exemplary embodiment is divided into two partial containers 3, 4 by vertically extending partition walls 2.
  • An outlet opening 5, 6 is provided on the underside of each partial container 3, 4.
  • a delivery channel 7, 8 is in turn arranged below each of the outlet openings 5, 6.
  • each conveyor channel 7, 8 there is a conveyor screw 9, 10f filling it, each of which is driven by a shaft 11 or 12 and a motor 13 or 14.
  • each delivery channel 7, 8 an outlet opening 16 and 17 is provided in the bottom 15 thereof.
  • the outlet openings 16, 17 are covered by inherently elastic flaps 18 made of plastic that open downward under pressure.
  • the outlet openings 16, 17 open down into a container 19th
  • a mixing device 20 is arranged in the container 19, which extends over the entire width of the conveying channels 7, 8.
  • the mixing device 2o comprises a plurality of mixing tools which are fastened to a common shaft 21 which is driven by a motor 22 and is mounted in a bearing 23 which is only shown schematically.
  • a screw section 25 is provided as a mixing tool in the area of the discharge opening 24 and below the outlet opening 16. This is followed by holding arms 26 attached to the shaft 21 tangentially rotating mixing blades 27, which - as is not shown in the drawing - are set to the axial direction. Finally, in the end region of the container 19, mixing blades 29 are provided, which are attached to the shaft 21 and hold the container 19, via holding arms 28.
  • a water pipe 3o opens into the container 19, which is also only shown schematically and in which an electrically actuated metering valve is arranged.
  • the top wall 31 of the container 19 is independent of the bottom 15 of the delivery channels 7, 8, i.e. there is no fixed connection between the conveying channels 7, 8 and the container 19.
  • the container 19 is rather connected via support arms 32, 33 to the weighing arms 34, 35 of a beam balance 36 which are pivotably mounted in the bearings 37, 38.
  • the bearings 37, 38 are attached to the housing cover 39, which is connected to the container 1 at 4o.
  • the weighing arms 34, 35 press against a force transducer 41, only shown schematically, in which e.g. Strain gauges convert the forces applied by the weight of the container 19 or the material contained therein into electrical signals.
  • the device described above is operated in such a way that a certain batch quantity and composition are preselected via the computer and storage device, not shown.
  • the one screw conveyor 9 is first set in motion and at the same time the motor 22 of the mixing device 2 0 .
  • a first mortar component for example binding agent (cement)
  • cement is introduced into the container 19 via the conveying channel 7 and the outlet opening 16, and the change in weight is recorded via the scale 36.
  • the screw conveyor 9 is stopped.
  • the mixing device 2o continues to run, axially conveying it away from the outlet opening 16 or the discharge opening 24.
  • the metering of a second mortar component for example sand, is now carried out in the same way via the screw conveyor 10.
  • the two components are already mixed during the addition of the second component. Even before the addition of the first mortar component, water can also be added and mixed in via the water pipe 3o in a likewise preprogrammed quantity. After a pre-programmed mixing time, the direction of rotation of the motor 22 is reversed and discharged through the discharge opening 24 ready-to-use mortar.
  • the overall arrangement is such that the cleaning effort, which is customary in conventional mortar mixing machines, is minimal, since the entire system can be largely self-cleaning.
