Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe processing, in particular to a large-diameter PE pipe extrusion molding cooling device. Background Art

[0002] A large-diameter PE pipe extrusion molding cooling device is a device specially used in a plastic pipe production line. Its main function is to quickly cool and shape the thermoplastic pipe just extruded from the extruder.

[0003] After extrusion, PE pipes need to be quickly cooled and shaped to maintain the stability of their shape and size. Therefore, a molding cooling device is needed. However, due to the relatively simple design structure of traditional molding cooling devices, it is not convenient to recycle the coolant and it is not convenient to disassemble the fan. Failure to recycle the coolant means that new cooling water must be discharged and re-injected after each use, which will lead to a huge waste of water resources. At the same time, frequent replacement of coolant will increase costs such as water charges and sewage treatment fees. In the long run, this will significantly increase the operating costs of the production line. If the fan is damaged or its efficiency decreases, the non-detachable design will make replacing the fan complicated and time-consuming, increasing maintenance time and costs. Utility Model Content
