Definitions

  • the invention is directed to a method for producing construction foam from air, water, foaming agent and an additive, in particular cement foam.
  • the invention is therefore based on the object of providing a method and a device which is suitable for carrying out the method and which makes it possible in a simpler manner Way to produce and process light foam.
  • cement slurry is injected under high pressure into a mixing chamber and mixed with a foaming agent and that the mixture is fed directly behind it to an expansion nozzle into which compressed air is injected in a metered manner.
  • the cement foam is produced in a single operation, which, owing to its low density, can be conveyed to higher floors solely by the high pressures of the injected additives in a hose connected to the expansion nozzle, without the need for a complex screw pump or the like.
  • the quasi one-step production of the cement foam according to the invention instead of the mixture of cement slurry with a previously produced foam also enables a much lower foam density of about 250 to 400 kg / cm 3 to be achieved.
  • the invention provides a valve block with connections for the cement slurry, of the foam agent and the compressed air as well as an outgoing foam line, the outlet axis of the injection-mixing nozzle for the cement slurry-foam agent mixture being transverse, essentially perpendicular to the expansion nozzle aligned with the outlet axis of the compressed air injection nozzle.
  • the arrangement according to the invention makes it possible to achieve a valve block that can be built very small, in which the externally operable setting wheels of the injection nozzles, which are preferably designed as metering valves, for the cement slurry, the foam agent and the compressed air nevertheless protrude in various directions in a manner that is easy to operate, with a very particular advantage Injection nozzles are to be arranged interchangeably in a block which has the connecting bores to the outer connections and between different injection nozzles.
  • connection 2 for a hose for the injection of cement slurry and a connection 3 for a compressed air hose and finally a further connection 4 for the foaming agent, while at 5 a connection for the outgoing cement foam line is indicated.
  • the cement slurry sucked in via a pressure pump and introduced at about 28 bar via the connection 2 is injected with the aid of an injection valve 5 with an adjusting wheel 6 a mixing chamber 7 is injected, into which the foam agent is also injected via a second injection valve 8 with setting wheel 9.
  • a transversely extending expansion nozzle 10 is arranged, the axis of which is flush with the outlet axis of a compressed air valve 11 with a setting wheel 12, so that the compressed air introduced via the connection 3 immediately after it emerges into the mixing chamber 7 with the cement slurry-foam agent mixture to mix, this mixture foaming directly in the expansion nozzle 10 to form a cement foam with a low foam weight due to the high pressure, so that no further pump or the like is required at all for the further transport of this finished cement foam to the processing site.
  • the high pressure of approx.
  • 25 bar in the foam line for example a 3/4 "line, which can be connected to the foam outlet 5, enables this foam to be conveyed automatically even to higher floors, since the weight of the foam in a 10 or 15 m long lines is still so low that the high pressure in the expansion chamber is still sufficient for automatic delivery.
  • the various nozzles 5, 8, 11 and 10 are preferably screwable as replaceable parts 5a, 8a, 11a and 10a into corresponding bores in the base body 1, so that a very simple exchange in the event of damage or wear and tear during use is possible without any problems.
  • the invention is not restricted to the exemplary embodiment shown.
  • the arrangement could of course also be used of the nozzles in a different way. What is essential, however, is the quasi one-stage foaming while avoiding the previous two-stage process, in which a finished foam is only subsequently mixed with the additive.
