When it drops to a certain distance, the cooling water in the cooling box 5 will submerge the placement box 3, and the filter box 26 can filter the particulate impurities generated during quenching. At this time, the water vapor generated during quenching is extracted by the air intake funnel 1 and enters the water storage tank 12 through the first pipe 9. The water pipe is connected to the third pipe 14. The cold water passes through the third pipe 14 and is finally sprayed out through the sprinkler nozzle 6. The sprayed cold water meets the water vapor and falls into the water storage tank 12. The filter screen 21 can block impurities in the water vapor. When the cooling water in the cooling box 5 is less, open the valve 10, and the cooling water in the water storage tank 12 enters the cooling box 5 through the second pipe 11, thus completing the quenching work of the bolts after heat treatment.
