The end of the connecting pipe 21 close to the normally open air inlet valve 22 is used as an air inlet. The normally open air inlet valve 22 is at the starting end of the connecting pipe 21. The water inlet mechanism 3, the normally open air inlet valve 22 and the first electromagnetic on-off valve 27 are opened, and water enters the atomizing nozzle 29 from the water inlet mechanism 3.

[0031] At the same time, the water inlet pipe 31 is fixedly connected to the connecting pipe 21, and is communicated with the atomizing nozzle 29 and is located on the side of the connecting pipe 21; the normally open water inlet valve 32 is fixedly connected to the end of the water inlet pipe 31; the second filter 33 is fixedly connected to the water inlet pipe 31; the fourth pressure reducing valve 34 is fixedly connected to the water inlet pipe 31 and is located behind the second filter 33; the second pressure gauge 35 is fixedly connected to the side of the water inlet pipe 31 and is located behind the fourth pressure reducing valve 34; the water flow controller 36 is fixedly connected to the water inlet pipe 31 and is located behind the second pressure gauge 35; the third electromagnetic on-off valve 37 is fixedly connected to the water inlet pipe 31 and is located behind the water flow controller 36; the second digital pressure detector 38 is fixedly connected to the side of the water inlet pipe 31 and is located behind the third electromagnetic on-off valve 37; the second flow monitor 39 is fixedly connected to the water inlet pipe 31 and is communicated with the atomizing nozzle 29. The end of the water inlet pipe 31 close to the normally open water inlet valve 32 serves as a water inlet. The normally open water inlet valve 32, the third electromagnetic on-off valve 37, the normally open air inlet valve 22 and the first electromagnetic on-off valve 27 are opened, and water enters the water inlet pipe 31. Then, the water enters the atomizing nozzle 29 through the water inlet pipe 31. The compressed air enters the connecting pipe 21 through the normally open air inlet valve 22 and finally enters the atomizing nozzle 29, so that the water is more delicate when sprayed from the atomizing nozzle 29, thereby preventing the surface of the casting from cold shock cracking; the second filter 33 is used to filter impurities in the water, and the fourth pressure reducing valve 34 is used to adjust the water pressure in the water inlet pipe 31; the second pressure gauge 35 is used to detect the water pressure, the water flow controller 36 is used to control the water flow in the water inlet pipe 31, and the second digital pressure detector 38 is used to detect the water pressure in the water inlet pipe 31, and an alarm is issued when the water pressure is too low.

The fan 42 sprays high-pressure air onto the surface of the casting to disperse the air film generated between the water mist on the surface of the casting and the high-temperature casting, so that the water mist and the high-temperature casting can directly contact each other to take away the heat on the casting.

[0033] Furthermore, the dust hood 51 is fixedly connected to the support frame 1 and is located above the support frame 1; the dust removal air volume detector 52 is fixedly connected to the dust hood 51 and is located above the dust hood 51. The dust hood 51 seals the casting, which is conducive to collecting dust caused by the casting when blowing air, and removes dust through a dust collector (another device), and discharges the blown cold air and evaporated water vapor. The dust removal air volume detector 52 monitors the dust removal air volume in real time and compares it with the air volume of the blower 4 to ensure negative pressure in the dust hood 51 and prevent dust from leaking out.

[0034] Finally, the protection part 61 is fixedly connected to the dust cover 51 and is located at the side of the dust cover 51; the temperature detector 62 is fixedly connected to the protection part 61 and is located inside the protection part 61.

[0035] When the present invention is used, the high-temperature casting is transported to the casting cooling system through the conveying equipment. First, the temperature of the casting is detected by the temperature detector 62. The third electromagnetic on-off valve 37 and the first electromagnetic on-off valve 27 are opened by the control system. According to the measured temperature, the control system provides water of corresponding flow rate to enter the water inlet pipe 31. Then the water enters the atomizing nozzle 29 through the water inlet pipe 31. The compressed air enters the connecting pipe 21 and enters the atomizing nozzle 29 through the normally open air inlet valve 22, so that the water is more delicate when sprayed from the atomizing nozzle 29, preventing the surface of the casting from cold shock and cracking. At the same time, the fan 42 blows out cold air, and the gas protective layer generated between the water droplets and the hot casting is broken by blowing so that the water can contact the casting. The dust removal mechanism 5 discharges the blown cold air and the evaporated water vapor. The temperature detector 62 is set at the outlet to measure the temperature of the casting after cooling, so as to correct the ratio of temperature and water. The cooling method of the casting of the present invention can reduce the time required for cooling the casting, reduce the floor space and investment cost.
