Definitions

  • the invention relates to an injector, namely a device for processing a mixture, in particular a foam-like cleaning mixture.
  • the object of the invention is to provide a device for preparing a mixture, in particular a foam-like cleaning mixture, which is intended to overcome the disadvantages of the cited prior art.
  • the object of the invention is achieved by a device for processing a mixture according to claim 1.
  • the measures of the invention result in that with the proposed device for preparing a mixture, in particular a foam-like cleaning mixture easily enrichment values of the chemical substance of more than 5%, are made possible with the choice of suitable conditions to over 30%.
  • the liquid inlet communicates with the liquid nozzle by means of the liquid channel and in which the liquid channel is formed as a taper of the liquid inlet substantially concentric therewith, a mixing space in which Liquid nozzle terminates substantially as the end of the liquid passage, a center inlet, which ends substantially perpendicular to the direction of the liquid nozzle in the mixing space, a flow space, a connecting channel which connects the mixing space with the flow space and a compressed gas inlet, which is in communication with compressed air, and a Druckgasdüse, which ends in the flow space and which can be acted upon by the compressed air of the compressed gas inlet, it seems to have considerable design advantages, if the compressed gas nozzle substantially parallel to verbi tion channel is directed in the flow space.
  • the device has a further central inlet, which ends substantially perpendicular to the connecting channel and the compressed gas nozzle in the flow space and can be acted upon by a further agent.
  • the device can also be operated without, or in addition to, applying a chemical agent to the first central inlet, if the alternative or additional substance is not intended to be treated as a cleaning foam. If you give it air, a pre-dosed cleaning foam can be prepared.
  • the liquid channel has a further, substantially concentric taper, since then the holes can be drilled successively.
  • the mixing chamber will be substantially cylindrical and concentric with the liquid channel.
  • the connection of the connection channel with the mixing chamber will advantageously have a substantially concentric taper.
  • the liquid nozzle projects far beyond 50%, preferably about 70% in the mixing chamber (12).
  • the nozzle ends far behind the central inlet (14).
  • the distance between the liquid nozzle (8) and the connecting channel (18) is advantageously 4.0 to 8.0 mm, preferably 5.5 to 6.5 mm.
  • the liquid channel has a front part - namely the actual liquid nozzle - which is a bore of 1.0 to 2.5 mm, for a water pressure of 100 to 200 bar, preferably 1.2 to 1.6 mm , For a water pressure of 15 to 60 bar preferably 1.7 to 2.1 mm and the connecting channel is designed as a bore of 3.0 to 4.0 mm, preferably of about 3.5 mm.
  • the liquid channel should advantageously have a length of 12 to 20 mm, preferably of about 15 mm and the length of the thinnest hole 7 to 11 mm, preferably of about 9 mm.
  • FIG. 1 to 3 illustrated apparatus for preparing a mixture, in particular a foam-like cleaning mixture has a liquid inlet 4, a liquid channel 6 and a liquid nozzle 8.
  • the liquid inlet 4 communicates with the liquid nozzle 8 by means of the liquid channel 6.
  • the liquid channel 6 is formed as a taper 10 of the liquid inlet 4 is substantially concentric therewith.
  • the liquid nozzle 8 ends as the end of the liquid channel 6 in a mixing space 12 in which a center inlet 14 ends perpendicular to the direction of the liquid nozzle 8.
  • the device has a flow space 16, which is connected by means of a connecting channel 18 with the mixing chamber 12.
  • a compressed gas nozzle 22 which is brought by means of a compressed gas inlet 20 with a pressurized gas, in particular with compressed air in combination.
  • the compressed gas nozzle 22 is directed parallel to the connecting channel 18 in the flow space 16.
  • the liquid channel 6 has a further, essentially concentric narrowing 26.
  • the mixing chamber 12 is cylindrical and concentric with the liquid channel 6.
  • the connection of the connecting channel 18 with the mixing chamber 12 has a concentric taper 28.
  • the front part of the liquid nozzle 8 is formed as a bore of 1.8 with a length of 9 mm.
  • the connecting channel 18 is formed as a bore of 3.5 mm.
  • the distance between the liquid nozzle 8 and the connecting channel 18 is 5.82 mm in the present, advantageous and tested embodiment.
  • another center inlet is formed. This is perpendicular to the connecting channel 18 and the compressed gas nozzle 22, ends in the flow space and can be acted upon by a further agent.
  • the injector is made by welding of two parts, which in the following "female part” according to the FIGS. 4 to 6 and “male part” according to the FIGS. 7 to 9 to be named.
  • female part according to the FIGS. 4 to 6
  • male part according to the FIGS. 7 to 9 to be named.
