Abstract

This application provides a hot air circulating drying device for PC / PBT modified plastics, including a rectangular outer frame with an opening at the top and an internal cavity for accommodating several heating tube structures. Each heating tube structure includes a heating tube body, a mounting part, and a connecting part. The heating tube body has multiple U-shaped heat dissipation tubes along its length and is covered by a screen sleeve. The inner wall of the outer frame has a slot adapted to the mounting part, allowing for movable connection to achieve customized installation positions for the heating tube structures. Connecting holes on the connecting part enable electrical connection between adjacent heating tube structures via connecting wires, one end of which is connected to an external power source. A through hole is provided at the bottom of the outer frame, and a fan electrically connected to an external power source is located on the side opposite to the mounting base.
