AI Technical Summary
Existing polyester production drying equipment suffers from problems such as uneven hot air distribution, local airflow short circuits leading to prolonged drying cycles, increased energy consumption, and unsatisfactory drying effects.
A drying device comprising a vertical cylinder and a sleeve was designed. It utilizes a rotating air supply pipe and a spiral lifting mechanism to provide uniform hot air through a patented air supply pipe. Combined with a stirring rod and scraper, it ensures that the material is heated evenly. The drying process is monitored and controlled in real time by temperature and humidity sensors.
The drying device for producing polymerized polyamides ensures material uniformity and efficiency through rotating air ducts, stirring rods, and scrapers. It combines the uniformity and efficiency of polymerized materials with rotating air ducts and spiral lifting mechanisms, along with stirring rods and scrapers, to ensure uniform heating of the materials. The drying process is monitored and controlled in real time by temperature and humidity sensors.
