Definitions

  • the present invention relates to a snow cannon with a central compressed air supply line and a pressure water supply line surrounding it and arranged coaxially to it, the two lines being connected to one another by internal nozzles of the compressed air line, and the compressed air supply line in one in the direction of the compressed air supply at the front by one of at least three arranged centrally symmetrically End piece penetrated by outer nozzles delimits the interior of a spray head, none of the outer nozzles lying in the geometric axis of the compressed air supply line.
  • the mode of operation of such a snow cannon is essentially that a very low temperature arises in the interior, with condensation nuclei in the form of ice particles forming in the air / water mixture, around which the water is already partially freezing to snow.
  • the present invention is therefore based on the object to provide a snow cannon of the type mentioned, which allows a much better mixing of compressed air and pressurized water both in the interior of the cannon and after the jet emerges from the cannon (in this the latter case is to mix with the outside air) or to achieve a mixing ratio that can be achieved with the known snow cannons with significantly less energy expenditure.
  • the wall thickness of the annular space in the area of the inner nozzles is 1 to 3 times larger than the diameter of an imaginary bore, the area of which corresponds to the total area of all inner nozzle bores, divided by 3, the geometric axes of the inner nozzles having the geometric one Make an acute angle to the axis of the compressed air supply line.
  • the compressed air supply line is designated by 1, the compressed air duct 2 passing through it being connected to a compressed air source in a manner not shown.
  • the compressed air duct 2 is closed at its front end by a plug 3.
  • three lateral inner nozzle bores 4 are provided, which communicate with the compressed air duct 2 and whose geometric axes intersect the geometric axis of the compressed air duct 2 at an acute angle, preferably less than 15 °.
  • a baffle plate 5 is provided, which protrudes outwards perpendicularly to the geometric axis of the compressed air duct 2.
  • the distance between the front of the baffle plate and the inside of the end piece corresponds to twice to ten times the diameter of the inner nozzle.
  • the outer jacket 6 of the pressurized water supply is arranged coaxially with the compressed air supply line 1, the inner thread 6a of which serves to receive the external thread 7a of the spray head 7.
  • This arrangement has the result that an annular space 11 is created between the inner wall of the jacket 6 of the pressurized water supply line or the spray head 7 and the compressed air supply line 1, which for the sake of simplicity is referred to as an annular space.
  • the distance measured on a radius between the inner wall of the jacket 6 and the outer wall of the compressed air supply line 1 is of course to be equated with the wall thickness of the annular space 11.
  • the dimensions are chosen such that the wall thickness of the annular space 11 in the area of the inner nozzles 4 is 1 to 3 times larger than the diameter of an imaginary bore, the area of which corresponds to the total area of all inner nozzle bores 4 divided by 3. Furthermore, the wall thickness of the annular space II in the area of the baffle plate 5 corresponds at least approximately to that in the area of the inner nozzles 4.
  • an inner space 9 is delimited by its inner wall and the end piece 8, which communicates with the outside air via three through holes 10, none of which lie in the geometrical axis of the compressed air supply line 1.
  • the three through holes 10 any number of through holes could in principle be provided, but none of which may lie in the geometric axis of the compressed air supply line.
