Definitions

  • the present invention relates to a mixing device of pourable building materials, especially dry mortar, with a container, an agitator arranged in the container in the form of a vertical conveyor pipe open at the top and bottom and an upward conveying arranged in the conveying pipe Auger.
  • Mixer which is arranged in a container have rotating shaft, arranged on the blades through which the bulk material to be mixed is circulated. Through a suitable choice of arrangement and orientation of the Shoveling should be achieved so that the bulk material is as possible is mixed homogeneously. It is also known in a container to arrange two opposing waves of the type mentioned, to improve the mixing result.
  • a device of the type mentioned is from the DE-OS 21 21 244 known. So far not for building materials
  • the device used has one of the known mixers for building materials completely different and simple Building on.
  • the screw conveys the mix within the Tube up and through the top opening of the tube addition, so that the mix outside the tube in the container falls back down again from where it is after some time comes back to the lower opening of the pipe and further The course of the mixing process is conveyed upwards again in the tube becomes.
  • the mixer according to the invention does not the entire mix is always kept in motion and secondly gravity is optimally used for circulation.
  • the required to achieve a desired homogeneity Energy input is thereby compared to the known devices for mixing building materials significantly reduced.
  • the invention has for its object a device of the type mentioned above, which these disadvantages does not have.
  • the possibility of cleaning the agitator can be improved.
  • the agitator can be pulled up out of the container.
  • the mix can be mixed after the mixing process remain in the container, which according to a further embodiment the invention also as a transport and / or storage container can be used for the mix.
  • the agitator will then, if necessary after cleaning, in the next container introduced to mix the next batch.
  • the raw materials can already exist in the container be or be fed to the agitator after insertion.
  • the agitator is preferably cleaned in one with Detergents such as sand-filled cleaning containers.
  • Detergents such as sand-filled cleaning containers.
  • the agitator is after another Embodiment of the invention in pulled out of the container Condition preferably pivotable and in the cleaning container lowerable. This makes cleaning particularly easy fast and effective.
  • Mixable can be ventilated during mixing.
  • the ventilation element arranged on the conveyor pipe.
  • the ventilation element can be removed from the container together with the agitator pulled out and cleaned.
  • the Containers are kept very simple, which is the case later Use of the container as a transport and / or storage container has a cost-reducing effect.
  • Ventilation element on top of a funnel-shaped Extension arranged at the lower end of the conveyor pipe. In this way, a large-area ventilation of the mix is achieved and improves the fluidization of the mix.
  • a further increase in the ventilation area can be achieved by Arrangement of the ventilation elements on the booms can be achieved, which are carried by the conveyor pipe.
  • the interior an inert gas, in particular nitrogen, can be supplied to the container.
  • the supply of nitrogen displaces oxygen reducing the risk of dust explosions or excluded.
  • Nitrogen is added preferably on the one hand when inserting the agitator into the container, largely around the oxygen present in the container to displace, on the other hand cyclically during the mixing process. This has been used to prevent dust explosions proven to be particularly effective.
  • the inventive mixing device shown in Fig. 1 comprises a container 1 for receiving the material to be mixed, which consists of a circular cylindrical upper part 2 and a truncated cone-shaped lower part 3 exists. Furthermore is the container 1 at its top with a boundary wall 4 provided in which a central opening 5 is provided which can be closed by an attachable cover 6 is. At the bottom, the container 1 has a discharge shaft 7, which is flush with the frustoconical lower part 3 of the container 1 connects and by means of a slide 8 is closable. In particular, the container 1 a usually for transport or storage of the mix used silo.
  • the helix 14 is also on its outer circumference an upwardly angled edge 17 to accommodate the volume to increase the screw conveyor 12.
  • stir bar 18 is arranged, which before the Slide 8 located mix is conveyed into the mixing circuit.
  • a frame 19 is provided, which the Holds Tray 1 in its upright position.
  • the conveyor tube 9 is funnel-shaped at its lower end Provide extension 24, the lower edge of which Forms inlet opening for the mix.
  • a sieve fabric 25 put on, which as a ventilation element for the mix serves.
  • the mix By venting the mix through the screen 25 the mix is fluidized and thereby receives an increased Agility, which in turn leads to better miscibility leads and reduces the risk of agglomerate formation.
  • the supplied air Due to the expanded design of the delivery pipe 9, the supplied air is as large as possible on the Mixed material distributed. This supplied air enables one optimal flow behavior of the mix, especially with easily self-compacting products. That controlled After the mixed material flows in, the prerequisite for one optimal homogenization of the mix.
  • the arrangement of the fluidization on the delivery pipe 9 can serve any commercial silo as a mixing container 1.
  • feed devices can be shown here for an inert gas, in particular nitrogen be.
  • the feed can be, for example, like the feed of the Air from above through cover 6.
  • An addition device can also laterally in the upper part 2 of the Container 1 may be attached. Then the feed pipe 9, the screw conveyor 12 and the motor 15 together with the lid 6 again in the container 1 or on put this on, so that the container is now up is closed.
  • the container 1 at slightly Dust explosive substances, preferably supplied with nitrogen, largely around the oxygen present in the container to displace.
  • the mix can also be used Delivery pipe 9 with screw conveyor 12 through a separate opening added and then the container with nitrogen be filled. Now the mixing device can Motor 15 are put into operation.
  • the screw conveyor 12 is rotated by the motor 15 about the axis I set, the direction of rotation is selected so that the Helix 14 of the screw conveyor 12 mixed material within the conveyor pipe 9 promotes from the bottom up. From time to time nitrogen is further added to container 1.
  • the mix conveyed upwards leaves through the openings 11 in the pipe wall, the delivery pipe 9 and falls due to Gravity as indicated by arrows 20 back in Direction to the bottom of the container 1. There it slips Mixed material due to the conical shape of the lower part 3 of the container 1 according to the arrows 21 in the direction of the Inlet opening 10 of the conveyor pipe 9, where it again from the Screw conveyor 12 added and within the conveyor tube 9 is promoted upwards.
  • the agitator 9, 12 can be put together with cover 6 and motor 15 lifted out of container 1 and fed to a cleaning device, not shown here will.
  • the agitator 9, 12 in a cleaning silo filled with sand. By actuating the agitator, this is in the cleaning silo Freed from existing mixed material residues very quickly. Subsequently can the agitator 9, 12 for the next mixing process be returned to container 1.
  • the container 1 after the mixing process has ended and remove after lifting the agitator and to use it as a transport and / or storage container for the mix.
  • the agitator 9, 12 is then used for the mixture the next batch is introduced into another container 1, which is filled with substances to be mixed or is filled.
  • the Container 1 prefers conventional transport and / or storage silos be used, which is inexpensive and reloading makes the mix unnecessary.
  • Fig. 2 largely agrees the variant of Fig. 1 agree. It's just the ventilation elements 25 not on a funnel-shaped extension 24 attached to the delivery pipe 9, but to arms 27, which are attached to the conveyor pipe 9 so that the ventilation elements 25 near the frustoconical lower part 3 of the container 1 are. This allows the ventilation area be enlarged. But at the same time they remain Ventilation elements 25 connected to the delivery pipe 9.
