Definitions

  • the invention relates to a device for continuously mixing dry mortar with water at a construction site, in particular for mechanical plastering, which, following a storage container for the dry mortar, contains an intermediate container in which a loosening device is arranged, a mixing chamber provided with a water supply under the intermediate container and following this has a pump, in particular an eccentric screw pump, for removing the mixture (cf. DE-A 2 407 657).
  • the invention has for its object to expand the possibilities of continuously applying mortar including screed.
  • the device has a closable connecting piece on the side of the intermediate container for an additional device adapted to the device and, if necessary, attachable to it, consisting of a storage container for an additive and a continuous conveying device which flows from this storage container into leads the intermediate container of the device.
  • a variability is obtained which, for example, allows one and the same gypsum plaster to be used in the modifications, that it is somewhat stretched with sand or ash granulate for living rooms, that it is admixed with pearlite for ceilings, used unchanged for bathrooms and toilets with walls to be tiled is, and for special places, such as a fireplace, receives a structure-forming addition, such as round grain made of expanded glass or expanded clay or the like.
  • the modifications can serve not only for economy, but also for quality improvement and optimization to meet different requirements . Leanings can increase the bending tensile strength; in liquid screed they can significantly reduce the undesirable high water content. Expanded clay increases thermal insulation. It is possible to use aggregates that are available at particularly favorable local prices.
  • Fluid bed granulate (ash granulate) from coal-fired power plants comes into consideration here, which is often provided free of charge at the location of the coal-fired power station. It is an excellent additive due to its low weight and its favorable grain size.
  • the flue gas gypsum that now arises in many places as a result of desulphurization can also be used as an additive, which also brings with it a binding ability.
  • the introduction of the additives into the intermediate container provided with the loosening device is particularly important in the invention. This point, still above the water inlet in the dry area, but shortly before the mixing chamber and with the loosening device as a device that now already mixes the solids and, above all, already completely enough to avoid lumps due to the setting of the mortar with the moisture of the aggregate Avoiding has proven feasible.
  • dry mortar will be produced and used, which can range from the previous ready-mixed mortars to pure binders with regard to their factory-introduced additives.
  • the well-known ready-mixed mortar allows additional aggregates for quite a few possible uses.
  • the possibilities of the invention are, however, exploited the more, the less the factory addition contains the dry mortar.
  • mortars will be sought which do not necessarily require a surcharge at the construction site and which tolerate various additives, for which a certain basic set of surcharges could be appropriate.
  • the chemical additives such as exciters, retarders or accelerators, air entraining agents, water retention agents, etc., as a rule, like the binders, cement, lime, gypsum or anhydrite, belong to the industrially manufactured product, but can also be added.
  • the intermediate container does not necessarily have to be structurally separate from the mixing chamber. It could also have the shape of an extension of a predominantly cylindrical mixing chamber upwards and differ from the actual mixing chamber in that it lies in a dry area. On the other hand, if one accepts a large overall height, an intermediate container in the form of a lowermost section of the storage container would also be conceivable. This intermediate container would then differ from the storage container by the range of action of the loosening device.
  • the conveying device of the additional device provided according to the invention should have an adjustable drive, preferably with a motor adjustable by a frequency converter, so that the proportion of the aggregate can be adjusted as required.
  • a proportioning screw is particularly suitable for measuring the proportion precisely.
  • the conveying device further comprises a screw conveyor arranged in the storage container for the aggregate near the bottom, and the Dosing screw has a shaft which is coaxial with the screw conveyor, preferably horizontal, and forms the connection between the storage container for the aggregate and the intermediate container of the device.
  • the connecting piece can expediently be closed by an insert which is flush with the wall of the intermediate container. Then there is no dead space (in the extension nozzle) if the additional device is not connected.
  • the drawing shows an embodiment of the invention.
  • the storage container 3 consists of an overall flat, approximately 50 ° against the horizontal inclined bottom 4 with a semicircular lower section and an adjoining rectangular upper section and a wall 5 attached to this floor such that the container widening upwards Cross section and an upper edge lying in a horizontal plane.
  • the bottom 4 has an approximately conical recess 6 coaxially with its semicircular lower section.
  • a gear motor 7 is seated from below, the shaft of which penetrates the bottom in a seal and is connected to a feed wheel 8.
  • the feed wheel 8 sweeps across the floor 4 with blades 9 and ejects the material through a recess 10 arranged in the floor at the upper end of its path.
  • a material-collecting intermediate container 11 is attached to the bottom and funnel-shaped in a lower section. It opens into a mixing chamber 12.
  • the mixing chamber 12 is provided with a stirring tool which has a shaft which is driven by a motor 13 arranged at the top and which at the same time drives an eccentric screw pump 14 which follows the mixing chamber 12 at the bottom.
  • a conveyor and loosening device in the form of a spiral 15 adapted to the funnel wall of the intermediate container sits on the shaft in the intermediate container 11. The spiral 15 sweeps over the funnel wall at a short distance and loosens the material and pushes it downwards.
  • a hose connection 16 is attached to the outlet of the eccentric screw pump 14.
  • a water fitting 17 for uniformly introducing the mixing water into the mixing chamber, an air compressor 18 for generating the spray air for plastering mortar and an air remote control switch 19 for switching the device on and off.
  • the additional device 20 has a storage container 24 for additives on a machine frame 23 supported partly on rollers 21 and partly on a bracket 22.
  • a feed screw 25 leads through the storage container 24 close above its bottom and, with the same shaft 26, merges into a metering screw 28 arranged in a tube 27.
  • the shaft 26, which carries the screw conveyor 25 and the metering screw 28, is driven by a geared motor 29 mounted on the outside of the storage container. This is infinitely adjustable by means of a frequency converter.
  • the metering screw 28 can thus be set to any delivery rate.
  • the tube 27 is inserted with its end at 30 tightly into a nozzle 31 formed on the funnel-shaped lower section of the intermediate container 11.
  • the device and the additional device 20 can both be loaded with sacked goods or in shovels. You can also get supplements to feed them with pneumatic conveyors. They can be placed under silos or on other containers, whereby the device can be loaded in this way and the additional device in that way.
