Definitions

  • the present invention relates to a snow cannon with a central compressed air supply line and a pressure water supply line which surrounds it and is arranged coaxially with it, the compressed air supply line opening into an interior of a spray head, which is delimited in the direction of the compressed air supply by a pierced end piece and serves as a pre-expansion space, with the compressed air supply line and the compressed water supply line from the compressed air line are provided in the form of bores penetrating the outer wall of the compressed air supply line, through which the compressed air exits into the pre-expansion space and mixes with the pressurized water.
  • the mode of operation of such a snow cannon is essentially that a very low temperature is generated in the pre-expansion chamber, with condensation nuclei in the form of ice particles in the air-water mixture, around which the water is already partially freezing to snow. These condensation cores are finally expelled or sprayed through a single, central front bore of the cover plate together with not yet frozen water particles and compressed air that is not involved in the snow production process, with the help of the condensation cores and the additional cooling that occurs on the outside of the central bore of the cover plate The compressed air in front of this central hole, including the cool ambient air, creates snow.
  • DE-A-29 41 052 also has as its subject a snow cannon, but in which an actual pre-relaxation space is missing.
  • the present invention is therefore based on the object, in addition to optimal, but energy-saving mixing of the media and pre-nucleation inside the device through increased involvement of the outside air in the mixing and condensation process to achieve a much cheaper energy utilization, and this with one - compared to that of the known cannons - much lower noise level.
  • the compressed air supply line has three identical inner nozzles
  • the end piece has three centrally symmetrically arranged outlet nozzles of the same diameter, none of which lie in the geometric axis of the compressed air supply line and the diameter of an outlet nozzle is 1 to 3 times the diameter of an inner nozzle corresponds.
  • the compressed air supply line is designated.
  • the compressed air duct 2 penetrating them in a manner not shown with a pressure fracture source is connected.
  • the compressed air duct 2 is closed at its front end by a plug 3.
  • three lateral nozzle openings 4 inner nozzles are provided, which communicate with the compressed air channel 2 and whose geometric axes intersect the geometric axis of the compressed air channel 2 at an acute angle.
  • inner nozzle is understood to mean a lateral opening in the compressed air supply wall, through which the compressed air reaches the area of the water and the pre-expansion chamber (9), as a result of which air and water are mixed.
  • a collar 5 is provided which protrudes outwards perpendicular to the geometric axis of the compressed air duct 2.
  • the outer jacket 6 of the 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.
  • the spray head 7 When the spray head 7 is screwed on, its inner wall or that of the outer casing 6 and the end piece 8 delimit a pre-relaxation space 9 which communicates with the outside air via three through-holes 10 which are arranged in a centrally symmetrical manner and none of which lies in the geometric axis of the compressed air supply line 1.
  • the three outlet nozzles have the same diameter, as do the three inner nozzles.
  • the diameter of an outlet nozzle is 1 to 3 times the diameter of an inner nozzle.
  • the arrangement of a plurality of through-holes 10 of the end piece 8 offset with respect to the geometric axis of the compressed air supply means that the mixture formed in the interior 9 is mixed much better the outside air is made possible by entraining the outside air, the aim of which is to be used for snow production, between two exit jets and, comparatively close to the nozzle, to mix with these exit jets to form a jet from the inside and thus much more completely.
