[0013] like Figures 1 to 2 As shown, a rapid cooling device for circulating water pipeline production comprises a placement seat 1, four corners of the bottom of the placement seat 1 are installed with supporting legs 2, the longitudinal section of the placement seat 1 is a trough-shaped structure, a plurality of conveying devices for conveying pipelines are arranged in the placement seat 1, a nitrogen tank 3 is placed below the placement seat 1, the outlet of the nitrogen tank 3 is connected to a liquid nitrogen pump 16, the outlet of the liquid nitrogen pump 16 is connected to a vertical connecting pipe 4, the vertical connecting pipe 4 is connected to a horizontal pipe 5, the horizontal pipe 5 is installed at the bottom of the bottom plate of the placement seat 1, a plurality of branch pipes 6 distributed at equal intervals and arranged vertically are installed on the horizontal pipe 5, the branch pipe 6 extends upward through the bottom plate of the placement seat 1, and an air cooling device is arranged on the top of the placement seat 1;

[0014] Specifically, after the water pipe is extruded through the screw extruder, the temperature is high and needs to be cooled. The water pipe passes through the placement seat 1, the water pipe is placed on the conveying device, and the liquid nitrogen pump 16 is turned on. The liquid nitrogen comes out of the liquid nitrogen tank 3 and enters the vertical connecting pipe 4, and then passes through the horizontal pipe 5, and finally is discharged from the branch pipe 6. When the liquid nitrogen is discharged, it will become a gas. During the gasification process of the liquid nitrogen, it will absorb a large amount of heat, so the water pipe can be quickly cooled.

[0015] The air cooling device includes a support rod 7 fixedly connected to the top of two vertical plates of the placement seat 1, a horizontal plate 8 is fixedly installed on the top of the support rod 7, and a plurality of fans 9 are installed on the horizontal plate 8; specifically, when the fan 9 is turned on, the fan generates wind to take away the heat of the water pipe, and at the same time, the blown nitrogen can be moved and distributed in the entire placement seat 1.

[0017] The branch pipe 6 is a universal bamboo tube; specifically, the universal bamboo tube can adjust the angle at will, which is more convenient to use.

[0018] The branch pipe 6 and the conveying device are arranged in a staggered manner; the positions of the branch pipe 6 and the conveying device do not conflict.

[0019] There are four supporting legs 2, two of which are arranged on each side. A cross bar 17 is fixedly connected between the two supporting legs 2 on each side. The two ends of the horizontal tube 5 are respectively located at the top of the cross bar 17 on both sides.
