Description

Technical Field

[0001] The utility model relates to the technical field of injection molding particle drying, in particular to a device for rapid drying of injection molding particles. Background Art

[0002] When producing plastic pellets, a high-temperature extruder is used to extrude plastic strips. After the plastic strips are immersed in water and cooled to form, they are transported to a pelletizer for segmented pelletizing. Before pelletizing, a drying device is used to remove most of the moisture on the plastic strips. However, after pelletizing, a certain amount of moisture will still remain in the plastic pellets. In order to ensure the dryness of the plastic pellets, a drying device is also used to dry the plastic pellets. The existing method is to place the plastic pellets in piles in a drying device and dry the plastic pellets at high temperature. However, when the piled plastic pellets are dried, water will accumulate at the bottom of the piled plastic pellets, which may easily cause uneven drying of the plastic pellets. If the drying time is increased, the drying efficiency will be reduced. If the drying temperature is increased, the plastic pellets will melt and stick together. Therefore, in order to solve the above problems, a rapid drying device for injection molding pellets is designed. Utility Model Content
