Description

Technical Field

[0001] This utility model relates to the field of drying equipment for the production of plastic granules. Background Technology

[0002] Plastic pellets are tiny plastic solids with fixed geometric shapes made from natural resins or recycled plastics through processes such as melting, extrusion, and pelletizing. They are the core intermediate form in the "raw material-product" link of the plastic industry chain, and almost all plastic products require secondary processing based on them as raw materials.

[0003] The existing publication number CN222201243U discloses a drying device for plastic granule production, including a drying box, a drying mechanism connected to one side of the drying box, the drying mechanism being used to dry the plastic granules inside the drying box, and a stirring mechanism being provided inside the drying box, the stirring mechanism being an electric screw rotating structure, a discharge mechanism being connected to the bottom of the drying box, and the discharge mechanism being used to break up the plastic granules and convey them to the next process, the stirring mechanism including a first rotating rod, a first motor being connected to the upper end of the first rotating rod, and rotating fans being symmetrically connected to the upper and lower parts of the first rotating rod; The device uses a first rotating rod to drive a rotating fan to stir the plastic granules, delivering hot air into the drying chamber so that the plastic granules are heated evenly during the drying process. A first gear drives a gear belt to rotate, which in turn drives a second gear to rotate a turntable. The stirring rod inside the turntable stirs the plastic granules, allowing the heat inside the granules to be evenly distributed, thus performing a secondary drying process. However, the rotating fan of this device uses unidirectional rotation, which can easily create blind spots in the stirring process. This prevents some granules from fully contacting the hot airflow, resulting in uneven drying. Furthermore, during the heating process, the surface of some plastic granules can easily become sticky due to temperature changes or the action of additives. The rotating fan of this device cannot effectively prevent the granules from contacting and adhering to the inner wall of the drying chamber, causing the granules to stick to the inner wall.

[0004] Therefore, it is necessary to provide a new drying device for the production of plastic granules to solve the above-mentioned technical problems. Utility Model Content
