Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to a PE pipeline processing extrusion cooling device which is easy to maintain. Background Art

[0002] PE pipe processing extrusion is a complex and delicate process involving multiple steps. First, the pretreated polyethylene resin needs to be put into the hopper of the extruder. Through the rotation and heating of the extruder's screw, the resin is gradually plasticized and pushed forward. The plasticized melt is extruded through the head and die to form a continuous tubular billet.

[0003] After extrusion, the PE pipe needs to be cooled by a cooling device to quickly form and fix it. The existing cooling device generally cools the pipe by spraying cooling water on the pipe surface. Over time, impurities and sediments are easily retained on the inner wall of the cooling device, which is not conducive to subsequent cleaning and maintenance. Therefore, a PE pipe processing extrusion cooling device that is easy to maintain is needed. Utility Model Content

Adjustment chambers 11 are provided at both ends of the bottom of the fixing plate 2, and a rotating part 13 is provided on one side of the adjusting chamber 11 through a transmission shaft 17, and a nozzle 14 is provided on the rotating part 13.

[0021] The cooling device body 1 is arranged at the discharge end of the extrusion equipment. After the PE pipe body 6 is extruded, it enters the cooling device body 1. The nozzle 14 sprays cooling water to cool the PE pipe body 6.

[0022] A housing 3 is provided at the top of the cooling device body 1, and a fan 4 is provided inside the housing 3. A dustproof net 5 is provided at the top of the housing 3 to prevent external dust from entering;

[0023] The main blades 18 are evenly distributed on the outside of the fan 4. The operation of the fan 4 drives the main blades 18 to rotate, drawing the external air flow into the cooling device body 1 and blowing air to the PE pipe body 6;

[0024] Auxiliary blades 19 are evenly distributed at the center of the top of the fan 4. The auxiliary blades 19 rotate in the same direction as the main blades 18, and air ducts are formed between the auxiliary blades 19.

[0025] The airflow generated by the rotation of the auxiliary blades 19 flows toward the main blades 18 and blows together with them into the interior of the cooling device body 1, thereby increasing the air volume and improving the cooling efficiency;

[0026] A water chamber 9 is provided at the bottom of the cooling device body 1, and water pumps 8 are provided at both ends of the water chamber 9. The output ends of the water pumps 8 are connected to the nozzles 14 through water hoses 7.
