Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic reprocessing, especially to a plastic particle recycling melting device. BACKGROUND

[0002] The waste plastic recycling technology is mainly recycling technology, which refers to the recycling of plastic products after classification, cleaning, crushing, dissolution and melting, and is used for further processing. Since the recycling of waste materials can turn industrial waste into valuable industrial raw materials, resource recycling is achieved, which has potential significance that cannot be ignored. During the production process, plastic particles that do not meet the size or shape requirements can be screened out and recycled through the melting device.

[0003] Please refer to the plastic particle recycling melting device with publication number CN218083653U. In this patent, it is pointed out that "the current melting device is prone to uneven heating of plastic particles during the melting process, resulting in uneven melting of plastic particles, and there are still plastic particles in the melted liquid, resulting in low quality of the melted liquid". The patent heats and melts the plastic particles after crushing them. In this process, the heating frame rotates outside the melting barrel to continuously heat the melting barrel with the heat emitted by the heating rod, so as to facilitate the stirring of the plastic particles with the stirring column, so that the plastic particles are evenly heated.

[0004] However, although the above-mentioned patent can realize the stirring treatment of plastic particles during the hot melting process, the stirring effect of the single-direction rotating stirring structure is not good, and there is no structure for turning over the plastic particles. The heat of the plastic particles near the melting barrel shaft is different from that of the plastic particles near the inner wall of the melting barrel, which can easily lead to uneven melting of the plastic particles. In addition, although the heating rod can rotate with the heating frame outside the melting barrel, the heat radiation area of the heating rod is limited, which can easily lead to low heating efficiency in the melting barrel. In view of this, the present application provides a plastic particle recycling melting device. UTILITY MODEL CONTENTS
