Description

Technical Field

[0001] The utility model belongs to the technical field of polypropylene particle processing, and particularly relates to a drying device for polypropylene foamed particles. Background Art

[0002] During the manufacturing process, polypropylene foamed particles may contain certain moisture and impurities, which will affect their subsequent processing and performance in use. Therefore, the main purpose of drying is to remove these adverse factors and ensure the quality and stability of polypropylene foamed particles.

[0003] In the prior art, particles are usually loaded into a container with ventilation holes, and then hot air is blown into the container for heating and drying. However, the particles to be dried cannot move, which will result in uneven drying. The unevenly dried particles will affect their subsequent processing and performance in use, and are not convenient for use.

[0004] In view of the above problems, the present utility model document proposes a drying device for polypropylene foamed particles. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a drying device for polypropylene foamed particles. The swinging assembly enables the hot air blower to swing and blow air, increasing the contact area between the hot air and the particles, improving the heat transfer efficiency, shortening the drying time, and solving the existing technical problems.

[0006] To solve the above technical problems, the present utility model is realized through the following technical solutions:

The swinging assembly enables the hot air blower to swing and blow air, increasing the contact area between the hot air and the particles, improving the heat transfer efficiency, and shortening the drying time.
