Abstract

The utility model relates to a man-made snow making machine, which is composed of an air compressor, a tank and a blow gun which are connected by pipelines, and a valve to control the air pressure and hydraulic pressure. The air through the compressor goes into the tank to make water have pressure; adjusting the valve makes the compressed air and the pressured water mixed in the spray gun pipelines; high speed jet flow makes the water pulverized into liquid drops and sprayed out from the opening of the spray gun; the theory that a part of calorific water after friction absorbs heat at the time of vaporization to make the surrounding water drops cooled and frozen is used to make the spraying water form snow and fall down. The utility model can make snow at the air temperature below +4 DEG C and the water temperature below +10 DEG C, and the snow density is between 0.32 and 0.44 g/cm [2].

Description

Snow making machine

The utility model relates to the snowmaker that a kind of water is made snow.

Utilizing the latent heat of phase change of ice to keep specific environment and be not subjected to or be subjected to external interference less, is a kind of means of Winter protection in modern age.Snowmaker is exactly that the artificial means of utilization that thereupon produce become water into ice, produces the special purpose machinery of the ice pellets of the physical characteristic that is similar to snow; It is more serious that artificial snow is subjected to the restriction of environmental condition in prior art, because only just begin to freeze at zero degree left and right sides water, therefore, artificial snow one is will be under the environment of zero degree, the 2nd, water temperature just can make snow by nearly zero degree, this just makes the artificial snow The Application of Technology be subjected to a lot of restrictions.

The purpose of this utility model be to provide a kind of can be in environment temperature+4 ℃, water temperature is lower than+snowmaker that 10 ℃ condition is snowed and can be utilized artificial method to make.

The purpose of this utility model can realize by following measure:

The utility model utilizes high velocity air to pulverize drop and makes the vaporization of part drop, and the drop cooling around the heat that is absorbed during the drop vaporization makes also crystallizes into the principle of snow and makes.It is made up of air compressor, fluid reservoir and spray gun three parts, connects with pipeline between this three part, and this pipeline is rubber hose.Air compressor provides the air-flow that has been compressed, store the water of pressure in the fluid reservoir, pass through by-pass valve control, with the compression air and have the water of pressure in the spray gun pipeline, to mix, and from gun slot, penetrate with the form of high velocity stream, this moment, part was vaporized through the water intensification of friction, according to physical principle water when liquid state becomes steam state, need to absorb the heat (latent heat of vaporization) of 597.34 card/grams, these heats obtain from the drop of environment on every side and not vaporization, it is solid-state that the drop that is not vaporized is become by liquid state in exothermic process, crystallizes into ice, falls so the high velocity stream that is penetrated by spray gun just becomes snowflake.

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and embodiment is described in further detail:

Fig. 1 is the structure chart of the utility model snowmaker, air through the air compressor compression passes through pipeline 1, a part flows to fluid reservoir 2 as the arrow indication, the pressure regulating valve of regulating on the fluid reservoir 23 can be regulated a compressed air that enters in the jar, also promptly control the pressure of pot liquid, this pressure generally is controlled at 0.6～2.0MPa.Open valve 4, by the road 5, there is the liquid of pressure to arrive spray gun 7, open Switch of spray pistol 6, water, gas mixture and jet ejection gun slot 8 are promptly arranged, the ice pellets that falls immediately is snowmaking.All valves of pipeline both can be manual, also can be automatic, when making snow, can control automatically all valves as large tracts of land.

Fig. 2 is the A-A cutaway view of gun slot of the present utility model, in order to make spray gun 7 air-water mixture can be ground into the high speed drop, this gun slot 8 is designed to rectangle, wide and length can be calculated according to the type of compressor, for example, embodiment of the present utility model is 1 * 20 millimeter or 1.5 * 25 millimeters two kinds.Shape as shown in Figure 2, the gun slot 8 of this shape can guarantee that jet is pulverized drop.

The utility model has been because taked above measure, and so can be equal to or less than in environment temperature+4 ℃ the time, water temperature is lower than+and 10 ℃ condition snows and makes, and the density of snowmaking is 0.32～0.44g/cm ²

Utilize such snowmaker to carry out artificial snow, be on the face of land and freeze the instability that disappears daytime night and freeze the stage, spray artificial snow, can play good insulation effect, effectively slow down soil layer and freeze downwards in the winter of northern China arid area; Also available artificial snow carries out fresh-keeping of vegetables, and spray certain thickness artificial snow at fresh vegetable surface winter, can both keep fresh, again frost bitten not.Utilize the snowmaking grain to suppress the flying upward of dust, environment purification simultaneously, effect also is very significant.
