Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation belt production, in particular to plastic particle drying equipment. Background Art

[0002] Drip irrigation tape is a key component of modern agricultural irrigation systems, enabling precise water delivery to the root zone of crops, improving irrigation water utilization and crop yields. Thanks to the strong corrosion and aging resistance of polyethylene resin, drip irrigation tape is protected from environmental influences during long-term use. Therefore, drip irrigation tape production typically uses polyethylene plastic granules as raw material, which are then melted at high temperatures. When exposed to air for extended periods, polyethylene plastic granules absorb moisture, resulting in excessively high moisture content. Directly melting these granules can lead to defects such as bubbles and shrinkage cavities in the finished product, impacting product quality. Therefore, before melting, polyethylene plastic granules are typically dried to reduce their moisture content. Currently, commonly used plastic granule drying equipment uses electric heating or hot air drying, typically storing the granules in a drying chamber for drying. Large accumulations of plastic granules can lead to slow drying times and high energy consumption. Furthermore, volatilization during the drying process produces odors, polluting the surrounding air. Therefore, there is a need for a plastic granule drying system that can avoid large accumulations, improve drying efficiency, and minimize ambient air pollution. Utility Model Content

[0005] Furthermore, the water absorption layer and the deodorization layer are both hollow reticular frame structures. The reticular frame structure of the water absorption layer is filled with adsorption resin, and the reticular frame structure of the deodorization layer is filled with activated carbon.

[0006] Furthermore, a collecting hopper is fixedly connected to the frame at the output end of the conveyor belt, and the lower end of the collecting hopper passes through the discharge port of the drying box.
