Definitions

  • This invention relates to a method and device for producing snow.
  • the invention aims at a method and device for artificially producing snow for covering snow pistes, ski courses and similar.
  • snow products having the same structure as natural snow, as well as products which are comparable to natural snow and thus are suitable for application, as aforementioned, for covering snow pistes and similar.
  • the present invention aims at a method for producing snow which is relatively simple and furthermore particularly suitable for producing a product comparable to snow which can be applied on ski courses, more particularly in-door ski courses.
  • the invention aims at a method for producing snow, with as a characteristic that it consists of forming ice and subsequently transforming this ice into snow or similar. Due to the fact that one works in two stages, more particularly a stage in which ice is formed and a stage in which this ice is transformed into snow or a product comparable thereto, a relatively simple method is obtained.
  • the ice shall be formed by freezing water in a freezing device.
  • this ice is formed in the shape of relatively thin pieces such as, for example, chips, with as an advantage that such pieces can broken up easily and can be transformed into snow or a product comparable thereto.
  • water is directed over a wall cooled below the freezing point, in such a manner that a layer of ice is formed on this wall, whereafter this ice is removed regularly from this wall by means of milling or scraping.
  • This technique has as an advantage that ice can be produced almost continuously.
  • the ice is transformed into snow by crushing and/or grinding it.
  • a crushing and/or grinding device shall be applied which is mounted together with the freezing device to a single unit.
  • salt preferably sodium chloride
  • salt is added to the water to be frozen. This has the advantage that the layer of ice which is formed on the aforementioned wall, is easier to remove, due to the less solid structure of the ice.
  • a stream of cold air shall be provided, for example, of approximately -5 degrees Celsius, in order to prevent the formation of water, on one hand, and/or the sticking together of the snow, on the other hand.
  • the invention also relates to a device which enables the production of snow according to the aforementioned method.
  • This device consists of a combination of a freezing device for forming ice out of water, and a device for transforming this ice into snow.
  • the freezing device preferably makes use of a wall cooled below the freezing point, of water supply means for bringing the water into contact with the aforementioned wall, and also of means for removing the ice formed at the wall from this wall.
  • the device for transforming the ice into snow preferably consists of a grinding and/or crushing machine.
  • Both devices namely, the freezing device and the device for transforming snow into ice, basically may be designed as separate units which either are installed at the same location or not, but preferably shall form one unit.
  • the method according to the invention substantially consists of two stages, whereby in a first stage 1, ice 2 is produced, whereafter in a second stage 3, this ice 2 is transformed into snow 4.
  • a device 5 which substantially consists in the combination of a freezing device 6 for forming the ice 2, and a device 7 for transforming the ice 2 into snow 4 or similar.
  • the freezing device 6 can be realized in various manners, preferably use shall be made of an embodiment as schematically represented in figure 2.
  • the freezing device 6 consists of a housing 8 in the shape of a vertical cylinder, provided with a wall 9 cooled below the freezing point. This wall 9 is provided with cooling means, such as a cooling circuit 10 with an inlet 11 and an outlet 12 for a cooling medium.
  • cooling means such as a cooling circuit 10 with an inlet 11 and an outlet 12 for a cooling medium.
  • the freezing device 6 further is provided with water supply means 13 for bringing water into contact with the cooled wall 9.
  • These water supply means 13 consist of an overflow reservoir 14, placed inside and in the upper part of the housing 8, with an overflow edge 15 which is situated at a small distance from the wall 9, as well as a supply conduit 16 for water.
  • the freezing device 6 comprises means for removing the ice 2 formed at the wall 9 from this wall 9, which, in this case, consist of a scraper 17, formed of a scraping element 18 which, by means of two arms 19 and 20, is fixed at a rotating shaft 22 which extends through the housing 8 and is driven by means of a motor 21.
  • the means for removing the ice 2 formed at the wall 9, and more particularly the element moving along the wall 9, may also have another form and not necessarily have to consist of a straight scraping element 18.
  • the scraping element 18, for example may be replaced by a milling cutter which then not only performs a rotation by means of the shaft 22, but, for example, also a rotation around its own axis.
  • a reservoir 23 for collecting surplus water may be provided. From this reservoir 23, a conduit 24, in which a pump 25 is provided, leads back to the supply conduit 16.
  • an outlet 26 is provided through which the scraped-off ice 2 leaves the freezing device 6.
  • the device 7 for transforming the ice 2 into snow 4 preferably consists of a grinding and/or crushing machine, whereby under a grinding and/or crushing machine any kind of device has to be understood in which the ice 2 is reduced in size.
  • interspaces are present in such a manner that the ice 2 is not completely crushed and is transformed into water, but is broken up and crushed up to a form which is comparable to snow.
  • these interspaces may be formed by grooves 31 and 32 which are provided in the respective surfaces of the rollers 27-28. It is, however, obvious that the interspaces concerned may also be created in another manner.
  • a stream of cold air of -5 degrees Celsius shall be supplied.
  • the complete device 5 is carried by a stand 33.
  • the working of the device 5 is as follows.
  • the supply conduit 16 water is permanently supplied to the overflow reservoir 14, in such a manner that water permanently flows over the overflow edge 15 and runs down along the wall 9.
  • the supply conduit 16 can be fed in any manner, either by means of a connection to a conduit network, or from a storage tank.
  • the surplus water which does not freeze is collected in the reservoir 23 and, by means of the pump 25, fed back to the supply conduit 16.
  • the scraping element 18 which performs a rotational movement by means of the shaft 22, driven by the motor 21, provides for that the thin layer of ice 2 is removed from the wall 9, as a result of which this ice 2 drops downward in chipped form and drops through the outlet 23 off the freezing device 6.
  • the ice 2 automatically drops into the device 7.
