Chu Xue spaces maintain -5 DEG C, it becomes possible to expeditiously and stably carry out artificial snow with the artificial snow-making speed of 12 ton hours.
Due to liquid nitrogen gasification speed quickly, so artificial snow-making speed is faster, the utilization ratio of the cold of liquid nitrogen is higher.
In addition, importantly, if hydraulic pressure, the setting of liquid nitrogen air pressure are higher in the utility model, artificial snow speed is just
Can be faster, correspondingly, liquid nitrogen utilization is higher, so as to meet not only to save resource but also expeditiously artificial snow.
Artificial snow system in the utility model can ensure the artificial snow-making speed of 8 stable ton hours, if improving pressure
Power artificial snow-making speed can also improve, and can also bring up to the artificial snow-making speed of 10~12 ton hours.
Fig. 3 is the structural representation of snow fluffy 5 of the present utility model, as shown in figure 3, Chu Xue spaces are snow fluffy 5, the snow fluffy 5
Top be provided with skylight 6, the skylight 6 be used for gas effusion, specifically, the skylight 6 could be arranged to 4.Need to illustrate
, the molal weight of nitrogen is 28, and air molal weight is 29, and nitrogen is slightly lighter than air, therefore the setting of skylight 6 is mainly
Escape for nitrogen.If being not provided with skylight 6, swollen quick-fried phenomenon may occur during artificial snow for snow paulin.This
Outside, the process of artificial snow-making must open skylight 6, although having the loss of a small amount of cold, not interfere with the quality of artificial snow.
In addition, in order to the situation of Real Time Observation artificial snow, multiple observation windows 7 can be provided with fluffy 5 side by avenging,
Preferably ten observation windows 7, hyaline membrane is provided with the observation window 7.
The cloth for avenging fluffy 5 uses PU material, and the tarpaulin of snow fluffy 5 is integrally fixed on support 8, and support 8 directly connects with ground
Touch, fluffy 5 are avenged in terms of outside and is nearly in the environment of a sealing, but is not proper sealed environment.
Snow fluffy 5 in the utility model can be configured according to the size of skiing racing track, and be fixed dimension, specifically
Size is 25m*4m*2m.
The special outlet passed in and out for artificial snow-making rifle 4, the special outlet VELCRO are provided with snow fluffy 5 in the utility model
Sealing.
Because artificial snow-making has strict requirements to the size and speed of droplet, thus explore droplet sizes, pressure, flow,
The relation of snow gun nozzle diameter etc., and then realize that the control of droplet size and speed is particularly important.It is specific real in the utility model
The result of existing artificial snow-making speed is calculated by precision, the latus rectum ratio of design water, gas and liquid nitrogen, water is fully atomized, and
And water and liquid nitrogen can carry out artificial snow-making with optimal proportioning, so as to save the dosage of liquid nitrogen, reduce cost.It is of the present utility model to make
Snow system can be applied in any environment, the experiment proved that, the system is nor affected in nearly 40 degree of summer of environment temperature
