In the process of ice slurry solidification, a small amount of water will be produced and drip onto the inner bottom of the ice slurry generating device 1. A liquid outlet 107 is also provided at the bottom of the ice slurry generating device 1. The liquid outlet 107 transports the water back to the water tank 5 through a pipeline. The ice slurry formed by the ice slurry generating device 1 is transported from the ice slurry output port 12 to the snowmaking device 2 through the ice slurry pipeline 3 to separate the ice slurry from snow and water. The separated water returns to the water tank 5 from the water outlet 22 through the water outlet pipeline 6, and the separated snow is sprayed to the outside of the equipment to form a circulating self-sufficient system, which can reduce water input to a greater extent, save costs, use up the water in the water tank 5, and eliminate waste.

Water is directly discharged from the water outlet pipe 6 into the water storage tank 5, and the water storage pipe 6 is not long. The water storage tank 5 is provided on one side of the snowmaking device 2, thereby reducing the material cost of the pipe. Preferably, the water storage tank 5 is a square plastic frame, which is convenient for following the transfer of the equipment and has low cost.

[0038] Further, the heat exchange device 19 is provided with at least one fluid inlet 191 and at least one fluid outlet 192. The heat exchange device 19 is further provided with a first outer plate and a second outer plate. An inner layer is disposed between the first outer plate and the second outer plate. At least one flow channel is disposed inside the inner layer. The flow channel is disposed between the fluid inlet 191 and the fluid outlet 192. Both the fluid inlet 191 and the fluid outlet 192 are disposed at the edge of the heat exchange device 19, which is convenient for adding fluid (i.e., refrigerant) or discharging fluid. An installation convex portion 193 is disposed on the outer periphery of the heat exchange device 19, and an installation hole 194 is opened on the installation convex portion 193.

[0040] In this embodiment, ice slurry is generated by the heat exchange device 19. After the heat exchange is completed, the cooled gas needs to be discharged. Some flue gas may carry some dust. The filter plates 15 installed on both sides of the housing 13 block the dust in the gas, achieving the effect of filtering the gas. The dust on the filter plates 15 is shaken off by the vibration motor 16, thereby preventing the filter plates 15 from being blocked. At the same time, the shaken-off dust falls onto the collection tank 17. Opening the baffle 18 can complete the cleaning and collection of the dust, and the dust can be cleaned off with water or gently swept away, thus solving the problem that it is inconvenient to clean the dust remaining on the inner side of the filter plate after filtration.

[0041] Preferably, the heat exchange devices 19 are symmetrically arranged in the housing 13. A spray pipe is arranged between the two heat exchange devices 19, and a number of nozzles are arranged on the spray pipe. When water flows into the drive shaft 103, it flows through the spray pipe and is sprayed out through the nozzles, spraying the water on the surface of the heat exchange devices 19.

The differential 254 is sleeved on the main shaft 251, and the main shaft 251 is connected to the drum 252 through the differential 254. The differential 254 mainly plays a role in protecting the transmission system.

[0045] One end of the main shaft 251 is provided with a mounting seat 2511. A connecting cylinder 255 is rotatably installed in the drum 252. A spiral blade is provided on the outer periphery of the connecting cylinder 255. The connecting cylinder 255 is connected to the mounting seat 2511 through a connecting bolt. The spiral blade is arranged between the connecting cylinder 255 and the drum 252, and the ice slurry is divided into two parts by rotation, becoming water and ice crystals. When the drum 252 stops rotating, the water flows out and is recycled through a pipeline from the fluid outlet, while the ice crystals enter the snow outlet passage and are blown out of the snow outlet by the blower in the snow outlet passage and blown into the air to form a snowing scene.

[0046] Preferably, the outer diameter of the connecting cylinder 255 is not less than 60 cm, so that the overall size of the whole equipment will not be too large and it is convenient to transfer.

[0047] In this embodiment, the power device 24 is started, and the power device 24 drives the filtration and centrifugation device 25 to rotate, dividing the ice slurry entering the drum 252 from the feed port 253 into two parts, becoming water and ice crystals. The water flows out and is recycled through a pipeline from the fluid outlet. The pipeline is arranged inside the filtration and centrifugation device 25. Then, the ice crystals are blown out of the snow outlet by the blower in the snow outlet passage under the action of wind and blown into the air to form a snowing scene, reducing the labor cost of artificial snowfall operation. A plurality of rollers for facilitating transfer are provided at the bottom of the machine base 23 to facilitate the movement of the equipment.
