Description

Technical Field

[0001] The utility model relates to the technical field of pipe production, in particular to cooling equipment for PPR pipe production. Background Art

[0002] Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, and long service life. They are widely used in various fields. During the production process, PPR pipes need to be cooled and shaped, so cooling equipment is used.

[0003] The cooling equipment used in the production of PPR pipes usually cools the pipes by a spraying or immersion water cooling method. The spraying cooling equipment continuously sprays low-temperature water on the surface of the pipe. The sprayed water takes away the temperature of the pipe surface after contacting the pipe, and then the cold water is discharged from the device. However, in actual use, the contact time between water and pipes is short, so the heat that can be taken away is small, and the temperature of the water itself does not increase much. Direct discharge causes energy waste. At the same time, the existing cooling equipment can only cool down in a single way, resulting in a longer cooling time required for PPR pipe production.
