Description

Technical Field

[0001] This utility model relates to the field of drying equipment, specifically to a drying device for ABS plastic granules. Background Technology

[0002] ABS is a high-strength, tough, and easily processed thermoplastic polymer material; it is a slightly yellow solid with a certain degree of toughness and a density of approximately 1.04–1.06 g / cm³. It has strong resistance to corrosion from acids, alkalis, and salts, and can also withstand the dissolution of organic solvents to a certain extent. It is widely used in the automotive, electronics, and home appliance industries. However, ABS material has slight hygroscopicity; if it is not sufficiently dried before processing, moisture evaporation can lead to defects such as silver streaks, deformation, pores, and bubbles on the surface of the product, seriously affecting product quality. Currently, operators often need to use drying equipment when drying plastic granules. While existing drying equipment can achieve basic drying and dehumidification functions, most rely on a single stirring method during the drying process, which cannot effectively increase the agitation of the granules. Even after multiple stirrings, the granules at the bottom cannot be turned over, thus failing to reduce the drying time. Utility Model Content
