Description

Technical Field

[0001] This utility model relates to the field of plastic granule drying technology, specifically a drying device for recycling waste plastic into granules. Background Technology

[0002] Waste plastic recycling and pelletizing is a core process that transforms recycled waste plastics into granular raw materials that can be reused in the production of plastic products through processes such as crushing, washing, drying, melt extrusion, and pelletizing. Among these processes, the drying step is a key pretreatment step that determines the quality of recycled plastic pellets, production efficiency, and the stability of subsequent processing.

[0003] Existing devices primarily dry plastic granules using a dryer. Many existing technologies are similar to drying devices for recycled plastic granules. The structure of device CN208006051U includes a housing, with a partition connected to one side. A gear ring is mounted on one side of the partition, meshing with a planetary gear. The planetary gear is fixed to a rotating shaft and meshes with a drive gear, which is fitted onto a main shaft. One end of the main shaft is connected to a motor, and large blades are mounted on the main shaft. The other end of the main shaft is fitted into a housing cover, and a rotating shaft with small blades is fitted into a countersunk hole in the housing cover. This invention allows for more thorough and uniform drying of recycled plastic granules and can dry various types of recycled plastic granules. However, there are still areas for improvement in this device.

[0004] Existing devices primarily dry plastic granules directly using drying equipment. This requires significant heat energy to evaporate the moisture adhering to the surface of the granules, hindering the rapid drying of the conveyed granules by a hot air blower. Furthermore, some devices struggle to move the conveyed granules within the drying chamber to the right and sequentially into the drain and drying drums, hindering continuous drying processes and reducing the device's efficiency and practicality. Therefore, to address these issues, a drying device for recycling waste plastic granules is proposed. Utility Model Content
