A high-efficiency drying equipment for plastic granules

Abstract

The invention discloses high-efficiency drying equipment for plastic granules, and relates to the technical field of plastic processing. The high-efficiency drying equipment for plastic granules includes a heating base and a thermal insulation cone, the bottom of the thermal insulation cone is fixed on the top of the heating base, the interior is hollowed out and the top is provided with an opening, and the bottom diameter of the thermal insulation cone is larger than the top diameter A central rotating shaft is rotatably installed at the bottom center of the inner wall of the insulating cone. The high-efficiency drying equipment for plastic granules can transport the plastic granules at the bottom of the insulation cone to the top of the insulation cone by setting the screw drive blade, and the plastic particles on the top of the insulation cone fall through the part between the partition and the insulation cone. To the bottom of the insulation cone to realize the up and down position of the plastic particles inside the insulation cone, which can not only improve the overall heating uniformity of the plastic particles, but also prevent the water vapor in the accumulated plastic particles from being released, and improve the plastic particles. drying efficiency.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a high-efficiency drying device for plastic particles. Background technique [0002] Plastic granules refer to granular plastics, generally divided into more than 200 kinds, with thousands of subdivisions. Common plastic particles include general plastics, engineering plastics, and special plastics. General-purpose plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane, etc. Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbon silicone, etc. Special plastics: thermosetting plastics, functional polymer plastics, such as artificial kidneys. [0003] The existing plastic particles need to be dried after being damp, but the existing drying method is to directly use a drying device to dry the accumulated plastic particles. This drying method will not only cause the accumulated plastic particles to be ...

AI Technical Summary

Problems solved by technology

[0003] Existing plastic particles need to be dried after being damp, but the existing drying method is to directly use a drying device to dry the accumulated plastic particles. In addition, the water vapor inside the stacked plastic particles cannot be released quickly during the drying process, which affects the drying efficiency. At the same time, the plastic particles close to the drying device may melt due to the high temperature of the drying device. , there is a large defect
