Definitions

  • the present invention relates to a jet head.
  • a blasting head such as a wet blasting head or a dry blasting head, is the end piece on the blasting hose of a blasting machine, such as a sand blasting machine, used to clean masonry, boat hulls and more.
  • the jet head S has an orifice M from which emerges a processing jet B 'consisting of water and granules.
  • the water is supplied at high pressure and takes the mixed in the jet head S granules at high speed with it.
  • Such known jet heads have the disadvantage that the beam is bundled and thereby only a relatively small area A, just in accordance with the area of the focused beam, can be processed at any moment. This results in relatively long processing times for given areas, for example, masonry or boat hulls, and in turn correspondingly high costs.
  • the present invention pursues and achieves the object to provide a jet head, with which the processing times and thus processing costs compared to those using conventional jet heads can be substantially reduced.
  • the invention provides a jet head containing jet expanding means.
  • the blasting head contains at least one blasting medium line and at least one conveying line for water and / or air, and the beam flaring devices contain a mouth section of the conveying line into the blasting medium line.
  • This embodiment can be developed with preference such that the mouth portion extends at an angle of entry not equal to 90 ° to a central axis of the blasting medium line in the region of the confluence of the mouth portion of the Strahlauf Weitungs noticeden with the blasting medium line.
  • Beam expander extends with the blasting medium line pointing past.
  • the areas of application of the blasting head are unlimited.
  • the jet head and in particular its nozzle unit and its components can be produced in different sizes.
  • the jet head as a wet jet head can be provided in particular that the amount of water to be injected is adjustable, so that wet and wet can be blasted.
  • the blasting head and in particular also the nozzle unit and its components need not be changed. Air is merely blown into the line carrying water at a wet jet head. Firstly, this keeps the nozzle free and, secondly, in particular also the jet pattern continues to be favorably influenced. Thus, a clogging of the water or just then air duct, generally speaking the transport line, is prevented by blasting media and this leads to an improved spray pattern.
  • the nozzle unit is preferably constructed in several parts, so that damaged or worn parts can be replaced individually.
  • Injected water even at high pressures, is not noticeable as a recoil to the operator; the energy is used up in the center piece for mixing / swirling of the media water and / or air as well as blasting media.
  • the invention further provides a jet head, in which a sealing ring for widening a connection end of a blasting medium supply hose is provided within a blasting agent connecting piece, in particular a hose holder.
  • the sealing ring according to the invention always ensures a good and firm seal and a proper transition from the hose into the blasting medium connecting piece, in particular the hose holder, possibly the jet on Weitungs solden and / or (even if the latter are not provided) in a venturi, even if the Hose end not exactly shaped (eg not cut absolutely straight) and / or inserted into the hose holder (eg not absolutely straight).

  • the invention is merely exemplified in more detail, ie it is not limited to this embodiment and application example or to the feature combinations within this embodiment and application example. Process and device features result analogously also from device or process descriptions.
  • FIG. 1 An embodiment of a blasting head S is shown in Figs. 1, 3, 4, 5, 6a, 6b, 6c, 6d, 7a, 7b, 7c, 8a, 8b, 8c and 8d in different views for clarity of construction and operation and will be described in more detail below with reference to these figures.
  • the jet head S consists in the present embodiment, as shown in FIGS. 1, 3, 4, 5, 6a, 6b, 6c, 6d, 7a, 7b, 7c, 8a, 8b, 8c and 8d can be seen in detail from:
  • Hose holder or generally blasting agent connecting piece 1 for example made of aluminum
  • Sealing ring 2 e.g. made of stainless steel or boron carbide (also referred to as hose sealing ring), sealing rubber 3, - beam expander 4 in the form of a Einschubverschl constitutionrohrs 9 with a
  • the beam widening devices 4 which are designed, for example, in the form of the slide-in wear tube 9 with a water guide bore 10 as the mouth section 11 of the beam widening devices 4.
  • This embodiment includes in the embodiment according to particular FIGS. 4 and 5, that the mouth portion 11 or in the present case, the Wasserleitbohrung 10 in which an entry angle is not equal to 90 ° to a central axis Z of the blasting medium L, which is predetermined by the blasting medium connection piece 1 and to which the insertion wear tube 9 also belongs, in the area of the coming together of the mouth section 11 of the beam widening devices 4 with the abrasive medium line L.
  • the mouth section 11 of the beam widening devices 4 extends at the central axis Z of the blasting medium line L in the region of the confluence of the mouth section 11 of the beam widening devices 4 with the blasting medium line L.
  • the mouth portion of the beam broadening means is perpendicular to and central to the center axis Z of the blasting means.
  • the means of transport such as water, is therefore according to the state of
  • the transport is not direct, such as directed centrally into the beam from the blasting agent in the blasting medium, but is at least partially directed tangentially into the beam from the blasting agent.
  • the means of transport is thus due to the location and alignment of the mouth portion 11 of the beam widening means 4, or in the present case concretely, the water guide bore 10 in the slide-in wear tube 9, forced into a spiral-like insertion path within the abrasive medium line L.
  • Fig. 7d is still an embodiment of a Einschubverschl accomplishrohrs 9 with a
  • the slide-in wear tube 9 is provided with a projection 15, which is also shown in FIGS. 7a, 7b and 7c.
  • This projection 15 of the Einschubverschl istrohrs 9 protrudes into the venturi 8 and more precisely in the boron carbide core 16 so far that the water outlet opening 17 can not be closed by blasting.
  • FIG. 9a, 9b and 9c each in a schematic Longitudinal sectional view and in Fig. 9d a cut and partially schematic representation are shown.
  • FIGS. 9 a, 9 b and 9 c each show, in a schematic longitudinal sectional view, an exemplary embodiment of a tubular sealing ring or, in general, a sealing ring 2, wherein
  • a Strahlmit- telzu Foodschlauches 12 is indicated, which is hereinafter referred to simply as a hose 12 for simplicity.
  • the sealing ring 2 has a hose 12 facing the pressure side, which tapers in an end edge or an end edge 13 tapered.
  • the taper may be on both sides, ie from inside and outside, or only on one side, ie only from the inside to the outside or only from outside to inside, be formed, as Figs. 9a, 9b and 9c illustrate.
  • the taper may be straight or curved (rounded) and not necessarily form a sharp or sharp end edge 13, but may also form an end edge which is narrower than the material thickness of the sealing ring 2 in the rest.
  • the sealing ring 2 can not be made arbitrarily thin, so that the taper is effective towards the end edge or the end edge 13.
  • FIG. 9b shows how the connection end 14 of the tube 12 deforms due to the end edge pressed in or the end edge 13 pressed in, which advantageously leads to a better and more secure fit of the tube 12 in the hose holder 1 leads.
  • an inner shoulder is formed in the tube holder, against which the tube rests with its connection end.
  • the sealing ring 2 always ensures a good and firm seal and a proper transition from the hose 12 into the blasting agent connection piece, in particular the hose holder 1, possibly the beam widening devices 4 and / or (even if the latter are not provided) into the venturi 8 Even if the hose end 14 is not exactly shaped (eg not cut absolutely straight) and / or in the hose holder 1 (eg not absolutely straight) is used.
  • the generated jet width can be regulated by changing this pressure.
  • the pressure By increasing the pressure, an increasingly broadening jet is obtained.
  • the beam can also be optimally adapted to the application requirements in terms of its width.
  • any other wet-jet cleaning incurred a high water demand and a high wastewater residue.
  • a circulation filter system which is characterized in that it is modular and mobile.
  • the filter unit is designed for the chemical-free cleaning of facades, hulls and other wet blast cleaning.
  • FIG. 10 represents a schematic perspective view of an exemplary embodiment of a circulation filter system.
  • filter basins B are stacked flush with one another and secured with connecting straps 21.
  • the basins B are e.g. made of salt-water-resistant aluminum and each equipped with two carrying handles 22 so that they can also be easily transported by hand.
  • the wastewater seepage is limited at the place of use and conveyed with a suitable pump to an inlet point 23 of the filter basin B, ie a first filter basin B 1.
  • a baffle 24 distributes the dirty water relatively evenly to a first filter 25 which is mounted on a perforated plate or grid.
  • the coarsely filtered water flows without pressure through a second filter mat 26 on the bottom of the first basin B and rises to an overflow support 27 (about 15 - 20 cm in height).
  • dirt particles can settle here before the dirty water runs into a second basin B2 and reaches the second basin floor through two fine filter mats 28.
  • the water must first also 15-20 cm rise to get over a spout 29 in a third basin B3.
  • the overflow pipe 29 penetrates into the third tank B3 to about 5 cm above the ground and then rises about 30 cm to a float valve 30, which ensures that at a sampling point of a pneumatic pump 31 is always sufficient water. If not enough filtered water and if the water level drops, the float opens a valve for the supply of fresh water.
