Description

Technical Field

[0001] The utility model relates to the technical field of polymer material preparation, and more specifically, to a particle drying device used for polymer material preparation. Background Art

[0002] Polymer materials play a vital role in the modern industrial field. Synthetic polymer materials have properties that natural polymer materials do not have or are superior to them, such as lower density, higher mechanical properties, wear resistance, corrosion resistance, electrical insulation, etc. Therefore, they are widely used in various fields. Polymer materials are in the form of particles during the production process. During the preparation and processing, the particles need to be dried.

[0003] The Chinese patent with patent application number CN201920878304.6 discloses a plastic particle drying device, including a barrel and a heating device.

The first baffle and the second baffle are both welded and fixed to the barrel side wall, and the second baffle is provided at the bottom of the first baffle. A movable plate is provided at the bottom of the second baffle. The drying device is provided with a first baffle and a second baffle, and the plastic particles to be dried are placed through the feed port.
