AI Technical Summary

Technical Problem

In the existing technology, high-temperature drying methods have low drying efficiency for temperature-sensitive polymer particles and heat-sensitive resins, and have problems such as uneven drying, high moisture residue, and particle agglomeration.

Method used

A gas circulation system driven by a circulating pump, combined with a dehumidifier and a vibration mechanism, prevents particle agglomeration through forced convection and dehumidification, controls the drying temperature through a heating element, and achieves precise drying control using a moisture detector.

Benefits of technology

It significantly improves drying efficiency, shortens drying time to 1/3 to 1/2 of traditional methods, ensures particle dispersibility and flowability, avoids uneven drying and clumping, and improves product quality.

Abstract

This utility model belongs to the technical field of drying equipment, and in particular to a drying device for granular chemical products. It includes a drying chamber, which serves as the main containment space for the entire drying process; a tray assembly installed inside the drying chamber for evenly placing the granular products to be dried; an airflow circulation pipe connecting the air inlet and outlet of the drying chamber to form a gas circulation channel; a circulation pump installed on the airflow circulation pipe for driving the gas to circulate within the pipe; and a dehumidifier installed on the airflow circulation pipe for removing moisture from the gas discharged from the outlet. By installing the airflow circulation pipe on the drying chamber, the airflow circulation allows for natural ventilation and cooling of temperature-sensitive chemical products that cannot be heated at high temperatures. Simultaneously, during the drying process, the vibration of the tray rack flips the granular chemical products on the trays, improving the drying efficiency.
