Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices, in particular to a screw cleaning device. Background Art

[0002] Fluoroplastic refers to plastics made of fluorine resin. The main varieties include polytetrafluoroethylene, tetrafluoroethylene-ethylene copolymer, tetrafluoroethylene-hexafluoropropylene copolymer and trifluorochloroethylene-ethylene copolymer. Because fluoroplastics contain fluorine atoms in their molecular structure, they have excellent electrical insulation properties, high heat resistance, outstanding oil resistance, solvent resistance and wear resistance, good moisture resistance and low temperature resistance, and are widely used in national defense, electromechanical, metallurgy, petrochemical and other industrial fields.

[0003] Since fluoroplastics have extremely high melt viscosity and a high melting point (between 200 and 300°C), when they are modified and blended through the conveying screw inside the processing equipment, if the ambient temperature is slightly lower than its melting point, the fluoroplastics will quickly harden and adhere to the screw. After the modification and blending is completed, the conveying screw needs to be cleaned. The existing cleaning solution is to heat and clean it with a handheld hot air gun after disassembling the screw. After each small section is cleaned, the surface of the screw must be reheated to allow the fluoroplastic attached to the screw to heat up to the melting point before cleaning can continue. The overall cleaning efficiency is low. Utility Model Content
