A plastic particle drying and stirring device for film production

Abstract

This utility model provides a plastic particle drying and stirring device for film production, relating to the field of drying equipment technology. It includes a drying tank with a circulating stirring and lifting mechanism inside. The mechanism includes a conical hopper, the lower end of which is fixedly connected to the inner bottom wall of the drying tank, and the outer side of the upper end of which is fixedly sleeved to the inner wall of the drying tank. Through the circulating stirring and lifting mechanism, with the help of an annular inclined guide plate, double spiral blades, and a vertical pipe, the plastic particles are dispersed, aggregated, lifted, and re-dispersed in a multi-stage circulation, extending the contact time between the particles and hot air, avoiding uneven drying in certain areas, ensuring smooth particle circulation, and improving drying uniformity and efficiency. Furthermore, the dual drying mechanism generates hot air through a fan and heating coil, which is then sprayed out from the air outlet through a diversion pipe and an annular mounting block. The hot air path is adapted to the particle circulation trajectory, achieving full-process drying from preliminary drying to deep drying, accurately covering the particles, improving hot air utilization, and enhancing the drying effect.
