Description

Technical Field

[0001] The utility model relates to the technical field of PVC production, in particular to an extrusion cooling device. Background Art

[0002] PVC, known in Chinese as "polyvinyl chloride," is a commonly used thermoplastic formed by the polymerization of vinyl chloride monomer. Its trade name is abbreviated as "chlorinated plastic." Pure PVC resin is a hard thermoplastic with a decomposition temperature very close to its plasticizing temperature and poor mechanical strength. Therefore, it cannot be used to mold products. Plasticizers, stabilizers, and fillers must be added to improve its properties to create PVC plastic, which is then processed into various products. PVC is categorized as rigid PVC and soft PVC depending on the amount of plasticizer added.

[0003] PVC pipes are typically produced using extruders. Due to the thermoplastic nature of PVC, the high-temperature PVC plastic needs to be cooled before it can be shaped. Existing PVC cooling methods typically involve directly placing the high-temperature pipe in water, which rapidly reduces the surface temperature of the PVC. This limits the area of ​​the PVC pipe that receives spray cooling, and the fixed spray angle prevents uniform cooling of the PVC pipe surface, impacting cooling efficiency. Furthermore, the cooling water cannot be quickly recycled. Utility Model Content

[0039] The implementation principle of this embodiment is as follows: when the PVC pipe is extruded from the extruder, it needs to be cooled in time. After the PVC pipe passes through the water tank 11, the spray component 2 on the water tank 11 sprays cooling water onto the surface of the PVC pipe, thereby cooling the PVC pipe. At the same time, the bottom of the PVC pipe is located inside the water tank 11. The cooling water in the water tank 11 will continuously cool the bottom of the PVC pipe, so that the PVC pipe can be cooled better. The cooled PVC pipe will pass through the drain box 14. The scraper component 3 located in the drain box 14 can scrape off excess water on the surface of the PVC pipe, so as to facilitate the subsequent processing steps to dry the surface of the PVC pipe. The water scraped off from the surface of the PVC pipe will be discharged into the water tank 11 through the drain box 14, and then reused after cooling treatment through the wastewater recovery component 4, thereby saving production costs and reducing the consumption of water resources.
