Abstract
A snow making nozzle assembly in which streams of water emerge from removable slotted nozzle plates and are injected into a high velocity air stream to atomize the water and project the atomized water into an atmosphere having an ambient temperature below 32 degrees Fahrenheit. The depth of slots in the removable nozzle plates vary to produce a more consistent snow pattern than prior art assemblies. The present invention has a higher operating efficiency due to the ability to easily clean the water nozzles and to adjust the water flow rate to match the existing atmospheric conditions.
Claims4
A snow making nozzle assembly for use in atomizing water and projecting the atomized water into atmosphere having an ambient temperature below the freezing point of the atomized water to form snow, said nozzle assembly comprising;
- a converging diverging flat nozzle extending outwardly from an inlet on the upstream side of said nozzle to an exit on the down stream side of said nozzle, a plurality of spaced water outlet slots machined into removable nozzle plates, said nozzle plates forming an integral portion of upper and lower flat surfaces of said converging diverging nozzle, the width of each of said slots in each of said nozzle plates being equal to the distance between said slots, the depth of the said slots increasing from a center slot of each of said nozzle plates to the outermost slot in said nozzle plates, by at least 20%, said slots being sufficiently angled toward the exit of said converging diverging nozzle to direct the atomized water out of said nozzle;
- upper and lower water distribution means overlying said upper and lower nozzle plates;
- means for supplying water under pressure to said upper and lower water distribution means for passage through said outlet slots in separate streams for atomization upon impact with a high velocity air stream, the atomized water being carried into the sub freezing atmosphere for the formation of snow.
