Description

Technical Field

[0001] This utility model relates to the field of PET bottle flake technology, specifically to a PET bottle flake drying device. Background Technology

[0002] PET bottle flakes refer to PET plastic material, which is a polymer produced by the combination of terephthalic acid and ethylene glycol. It has the characteristics of being lightweight, highly transparent, impact-resistant and not easily broken, and can also block carbon dioxide gas. However, due to previous use and storage, PET bottle flakes often have a large number of contaminants, which can have a very serious adverse impact on the recycling of PET bottle flakes.

[0003] Existing PET bottle flakes require drying after cleaning. Because PET bottle flakes are sheet-like, they tend to stick together after cleaning, preventing the internal PET bottle flakes from drying completely. This leads to mold growth during storage. Furthermore, traditional cleaning methods do not thoroughly remove contaminants from the PET bottle flakes, resulting in reduced cleaning quality. To address these issues, we propose a PET bottle flake drying device. Utility Model Content

[0013] 1. In this PET flake drying device, the cleaned PET flakes are conveyed to the water filter tank through the discharge port, filtered through the filter screen, and then conveyed to the drying chamber. The filtered water is discharged through the drain pipe. The booster pump blows the PET flakes that are stuck together through the air nozzle. At the same time, the servo motor drives the fan blades to rotate, so that the heat generated by the heating mesh plate can fully contact the PET flakes. The stirring motor drives the stirring rod to rotate, so as to stir the PET flakes. This makes the PET flakes dry more thoroughly and prevents mold from appearing during later storage.

An electric lifting rod drives a brush plate to descend and contact the PET flakes inside the translation plate. Simultaneously, an external water pump sprays water through a spray pipe. A variable frequency motor drives an incomplete gear to rotate within a U-shaped frame. When the incomplete gear contacts the upper teeth of the U-shaped frame, the translation plate moves to the left with the support of a track via a slider. When the incomplete gear contacts the lower teeth of the U-shaped frame, the translation plate moves to the right with the support of the track via a slider. This reciprocating motion of the translation plate, combined with the brush plate, cleans the PET flakes, resulting in a more thorough cleaning and improved cleaning quality.

This achieves the reciprocating motion of the translation plate 120, which, together with the brush plate 141, cleans the PET bottle flakes. The PET bottle flakes are cleaned. After cleaning, the electric push rod 123 is activated to move the baffle 124, exposing the discharge port 125. The flakes are then transported to the water filter tank 210 through the spring pipe on the discharge port 125 and filtered through the filter screen 211. The filtered PET bottle flakes are then transported to the drying chamber 200. The filtered water is discharged through the drain pipe 212. The booster pump 250 blows the PET bottle flakes that are stuck together through the air nozzle 220. At the same time, the servo motor 240 drives the fan blade 241 to rotate, so that the heat generated by the heating mesh plate 230 can fully contact the PET bottle flakes. The stirring motor 260 drives the stirring rod 261 to rotate, stirring and drying the PET bottle flakes. After drying, the PET bottle flakes are discharged through the discharge pipe 271 by opening the solenoid valve 271.
