Description

Technical Field

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

[0002] Polyethylene pipe is also called PE pipe. PE pipe is developing steadily in the current municipal pipe market in China. PE pipe, PP-R pipe and UPVC pipe all have a place, among which the strong development momentum of PE pipe is the most eye-catching. Polyethylene pipe needs to be cooled and shaped after extrusion. Now polyethylene pipe needs to be cooled after production. The existing cooling method is mostly water cooling. However, the existing cooling device uses nozzles for spray cooling when water cooling polyethylene pipes. However, the positions of the existing nozzles are mostly fixed, so the positions sprayed on the surface of the polyethylene pipe are the same, which easily causes the spraying position to be cooled, while other positions are not cooled, and the cooling is uneven. Therefore, we propose a cooling device for polyethylene pipe production. Utility Model Content
