Definitions

  • the invention relates to a method and an apparatus for producing snow according to the preamble of the independent claims.
  • snow cannons for generating snow from the prior art Known snow. Such snow cannons are used to secure the Guaranteed snow in ski areas. Disadvantage of the previously known Snow cannons is that they only operate at temperatures around freezing or including being able to produce snow. This is due to the principle of Snow production. With snow cannons, water is atomized finely and by a Blower blown, this water at a correspondingly lower Ambient temperature crystallizes and precipitates as snow. Disadvantage is here, as already indicated above, that such snow cannons only in the area work below freezing.
  • the present invention has for its object a method and a To propose a device for producing snow, with which, in essentially regardless of the ambient temperature, snow directly on site can be produced.
  • the task set is characterized by the distinctive features of the independent Claims resolved.
  • the invention is based on the fact that by means of a suitable device in known Way and continuously flake ice is produced, which in a mixing and Blower unit mixed with air and blown into the environment.
  • Flake ice is preferably produced in an actively cooled drum and is essentially independent of the ambient temperature.
  • the entire device is preferably designed and has a mobile device Sliding shoes or rollers so that they can be used to produce snow directly on site can be transported. Training as a stationary device is also possible.
  • the flake ice machine preferably consists of a cylindrical drum, whose inner surface is designed as a cooling jacket, which wets with water is so that an ice layer forms, which by means of a around the central longitudinal axis the drum rotating ice scraper is scraped off continuously and as Flake ice can be removed.
  • the thickness (thickness) of the flake ice leaves yourself in by regulating the water supply and the speed of the ice scraper change wide areas.
  • a significant increase in flake ice production is preferred Execution achieved in that in the drum coaxial to the outer cooling jacket at least a second inner cooling jacket is arranged, both on its radially inside as well as on its radially outer surface Water is wetted. As with the outer cooling jacket, here too assigned to the surface wetted with water each ice scraper, which around the Rotate the central longitudinal axis of the drum and the ice that forms on the cooling jacket scrape off. By using a second inner cooling jacket, the So increase the ice production rate by about the area ratio factor 3.
  • the mixing and blowing unit is intended to shred the flake ice and mix it with air, so that the volume is increased and the air is blown out
  • the mixing and blowing unit has a housing which is open at the top and in which a rotatingly driven cellular wheel is arranged.
  • the housing In the lower area of the housing there is an injection opening for the supply of compressed air and, approximately opposite the injection opening Depending on the position of the cellular wheel of the mixing and blowing unit, a cavity is formed between the housing and the webs of the cellular wheel, which is pressurized with compressed air through the blowing opening, so that the snow-shaped flake ice contained therein mixes with air and through the blowing opening This enables the snow to be transported over hose lines over 100 m and more, depending on the compressor capacity (increased mobility).
  • the flake ice is by means of a Conveyor from flake ice machine to mixing and blowing unit transported.
  • the mixing and blowing unit is direct is arranged on the flake ice machine, so that the conveyor is omitted.
  • the cooling jackets are cooled by means of a cooling generator, which is the Cooling jackets supplied with cooling fluid.
  • the Supply is essentially independent of the energy source, e.g. B. tension from Network, power generator, hydraulic power transmission etc. This has the advantage that smaller units are formed that are easier to transport individually and have it stationed on the ski slope.
  • the main advantage of the invention is the ability to snow even at temperatures above the freezing point and the mobility of the entire system, which thereby can be positioned directly at the place to be snowed. Since the device is a has active cooling and snow production, for example at minus 20 ° Celsius, the consistency of the snow produced is much better than that of conventional snow cannons. This means that the snow produced also at has a very good durability at higher temperatures. A very big benefit The invention lies in ensuring the snow reliability of the ski areas in Spring with warmer temperatures. Loss in sales, e.g. B. because of locked Valley runs can be avoided.
  • Another area of application is the trendy indoor ski arenas, which also include such a device can be inexpensively supplied with high quality snow can.
  • Figure 1 shows the mobile snow gun, consisting of a Frame construction 1, which with skids 2 or wheels (not shown) is provided.
  • This frame structure 1 carries the various assemblies of the Device, wherein in operation the frame structure 1 by metal or Plastic sheets (not shown) is clad.
  • the core of the snow generator is the flake ice generator 3, which consists of a actively cooled drum 4, which via a water meter 6 and the Water supply 7 water is supplied.
  • the supplied water freezes on the Inner wall of the drum 4 to ice and is solved by means of ice scrapers, which by a drive 5 are driven in rotation.
  • a cooling generator 8 is provided as cooling for this drum 4. This delivers a cooled cooling fluid, which the flake ice maker 3 via the line 12th is fed and leaves the drum 4 via line 11 again.
  • a heat exchanger 9 is provided, which cools the cooling fluid before entering the cooling generator 8.
  • a fan 10 can be provided. With increased cooling requirements Several heat exchangers can also be provided.
  • the flake ice 15 produced by the flake ice generator 3 occurs on the underside of the Drum 4 falls out and falls onto a conveyor 14 which contains the flake ice 15 conveyed in direction 24 and fed to a mixing and blowing unit 16.
  • the mixing and blowing unit 16 includes a housing 22 in which a cell wheel 17 which is driven to rotate in the direction of rotation 23 is arranged.
  • the Flake ice 15 is fed through the conveyor 14 and passes through an opening in the housing 22 and in the individual chambers of the cellular wheel 17th
  • the cellular wheel is driven by a motor 18.
  • the mechanical Effect of the cellular wheel 17, the flake ice 15 is crushed somewhat and arrives in the lower area of the housing 22, where an injection opening 20 is arranged, which is connected via a pipeline to a compressed air generator 19.
  • the Compressed air generated passes through the injection opening 20 in the lower region of the Housing 22 and the corresponding chamber of the cellular wheel 17, which crushed flake ice 15 is mixed with air and immediately by a blowing opening 21 lying opposite the blowing opening 20 as snow to the Environment is blown out.
  • a hose line can be connected to the outlet opening 21 be connected so that the snow is blown specifically to the site can be.
  • FIGS 3 and 4 show a longitudinal section or cross section through the Double-wall flake ice machine 3.
  • the flake ice machine consists of a approximately cylindrical drum 4, in which an outer cooling jacket 26 and at least one inner cooling jacket 27 are arranged, which with cooling fluid are flowed through, which is supplied by the refrigeration generator 8.
