The specific embodiment

Object lesson shown in embodiments of the invention are incited somebody to action with reference to the accompanying drawings illustrates.

Label 1 expression ice machine in Fig. 1, this ice machine is used for making sheet thin ice sheet, and various structures are arranged, because be known, omits explanation.

There is funnel 2 below of ice machine, and the thin ice sheet that the ice machine manufacturing is come out is fallen 2 li in funnel from the bottom outlet of ice machine.

There is ice crusher 3 below of funnel 2, and the pulverizing that is broken of the thin ice sheet of falling 3 li of ice crushers from funnel forms snowmaking.

The snowmaking that forms by ice crusher is supplied to pneumatic conveyer via the batcher that constitutes such as rotary batcher, carries out the air force feed by this conveyer to the skifield.

Come the air of air blast 10 of the primary side 5a of comfortable pneumatic conveyer to be admitted to batcher 4, be sent to the skifield from the snowmaking of batcher 4 from the secondary side 5b of pneumatic conveyer and scatter.

In a large amount of snow of needs, as shown in Figure 2, use many ice machines, and corresponding each ice machine is provided with a funnel, falls conveyer 6 from the thin ice sheet that each funnel falls, (for example spiral conveyer), collect by 1 ice crusher, form snowmaking, the snowmaking from batcher 4 is transported to the skifield, suitable distribution with pneumatic conveyer.

Air from the quilt of the air blast 10 of pneumatic conveyer primary side 5a heats up is cooled to the temperature approaching with outside air temperature through a cooler 11, dewaters through recoler 12 then, is transported to batcher 4.Snowmaking from batcher 4 is sent to the skifield distribution via pneumatic conveyer secondary side 5b.

Ice crusher has a pair of cylinder, and this is ground into snowmaking to the thin ice sheet to cylinder.One is for example shown in Figure 3.

7 li a pair of

cylinder

8a, 8b that have as shown in Figure 3 of housing of ice crusher shown in Fig. 1,2.Be formed with the pointed tooth row that a plurality of its triangle taper pointed tooths 9 form along circumferencial direction on the periphery of the cylinder cylinder width ground that lies across.Each cylinder is gone up the abridged driving machine with opposite direction rotation by figure, and the thin ice sheet of falling between the cylinder is further pulverized, and forms snowmaking.

Specifically being shaped as of pointed tooth: the bottom surface of pyrometric cone is an isosceles triangle, and two waists on long limit are along the roll circumference direction, and minor face is vertical with the roll circumference direction, is formed on the periphery of cylinder.

And the formed triangle bevel in the summit of minor face and pyrometric cone for example retreats about 6 degree with respect to direction of rotation and forms the cylinder periphery.

The pointed tooth of these triangle tapers is arranged continuously in the periphery of cylinder, forms the pointed tooth row, and pointed tooth is listed in width space-number millimeter, forms multiple row, constitutes a cylinder, becomes a pair of with another cylinder that constitutes with the same manner.Two cylinders rotate in the opposite direction synchronously, and foliated ice is pulverized, and generate snowmaking.

cylinder

8a and 8b, in periphery pointed tooth 9 is arranged.

But, about the shape of pointed tooth, 90 ° of angles are for example arranged in parallel continuous formation with the width of cylinder, have the ditch of the about 1mm of the degree of depth to the V word shape mountain valley of 2mm; And each for example has the ditch with V word shape mountain valley at 90 ° of angles and forms a cylinder and become a pair of with another cylinder that constitutes with the same manner with the parallel formation of the circumferencial direction of cylinder, two cylinders are according to ratio of revolutions for example about 1: 48 and produce revolution difference, by opposite direction rotation, thus the thin ice sheet of sheet is pulverized with the mode that grinds, generated snowmaking.

According to several ditches of the parallel formation of roll circumference direction, can allow the trash ice of certain a certain size particle diameter pass through, in view of the above, can suitably mix the snowmaking composition of particle in the composition of powder snow with a certain size.

In addition, suitably change the spacing and the V font angle of the profile of tooth ditch of cylinder Zhou Fangxiang and width, can generate snowmaking with various particle diameters distributions.

Fig. 5 has represented the example of another one ice crusher, lobe shape in the cylinder periphery, the for example ditch in the V font mountain valley of an angle of 90 degrees that has along the continuous formation of the direction parallel with the cylinder width, constitute a cylinder, become a pair of with another cylinder that constitutes with the same manner, the ratio of the revolution of a cylinder and another cylinder, will be iced and pulverize foliated ice according to opposite direction rotation as being about 1: 48.

Pointed tooth structure by such can grind refinement to the thin ice sheet of sheet, so, can produce the powder snow composition and account for most powder snow shape snowmaking.

In addition, the spacing of the profile of tooth ditch of suitable change cylinder width and V font angle can form the snowmaking that has various particle diameters distributions.

The invention effect

(1) because need not to make the used low temperature refrigerant of ice link and dehydration link and high temperature refrigerant Mutual flowing heat energy is not caused waste, thereby the artificial snow-making ability of unit interval is strong.

(2) should be and do not need warm dehydration procedure, does not dissolve on the ice surface of generation, thereby, can Not that to produce the surface is mixed with dissolving part and snowmaking freezing part, that quality is single.

(3) by the spacing between one pair of cylinder regulating the trash ice machine, can produce different Snowmaking is to adapt to and season, skifield that temperature is relevant.

For example, the skifield opened into about late April from the phase in severe winter of early October, can make Produce and meet the at that time snowmaking of temperature.

(4) can make the snowmaking that adapts to outdoor skifield and snow dome.

That is, as the snowmaking of skifield, although tiny powder snow can adapt to outdoor and Snow dome is if but only have powder snow composition, snowmaking in outdoor skifield Can must be floated up by wind, so, the distribution difficulty of snowmaking can be caused, but this device can To produce the snowmaking that is easy to scatter.
