Description

Technical Field

[0001] The utility model relates to a cooling device, specifically a cooling device for the production of polyethylene pipes, belonging to the technical field of polyethylene pipes. Background Technique

[0002] Polyethylene pipes are pipes made of polyethylene, which is a thermoplastic resin with high crystallinity and non-polarity. The appearance of virgin polyethylene is milky white, and it is semi-transparent to a certain extent in a thin cross-section. PE has excellent properties against most chemicals used in life and industry.

[0003] The utility model disclosed in the utility model patent with the publication number of CN218053908U discloses a polyethylene pipe extrusion cooling device, including a polyethylene pipe extruder body and a transmission device. In the utility model, the cooling water flows to the cooling box through a hose, so that the cooling box emits cold air, and then the cooling fan blows the cold air to cool the polyethylene pipe extruded by the polyethylene pipe extruder body. Then, water is poured into the water storage tank through the other end of the hose for recycling, solving the problem that the polyethylene pipe will generate a relatively high temperature when it is just extruded, because there is no structure for cooling the extruded polyethylene pipe.

[0004] After the production of polyethylene pipes is completed, the temperature is relatively high and the material is relatively soft. In order to cool down as soon as possible and plasticize the pipes, it is necessary to carry out a cooling operation on the pipes. Although the device in the above patent can cool the pipes, it can only cool one side of the pipes, and it is difficult to cool the pipes evenly in all directions, reducing the cooling efficiency of the pipes. Therefore, we provide a cooling device for the production of polyethylene pipes to solve the above problems. Content of the Utility Model
