Description

Technical Field

[0001] The invention relates to the technical field of plastic particle processing, in particular to a plastic particle degassing and drying device. Background Art

[0002] Plastic is a high molecular compound formed by polymerization of monomers through addition or condensation reactions. It has a medium deformation resistance, between that of fiber and rubber. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic is an important organic synthetic polymer material with a wide range of applications. It can generally be divided into two categories: thermosetting and thermoplastic. The former cannot be reshaped and reused, while the latter can be repeatedly produced. The different properties of plastics determine their uses in life and industry.

[0003] Plastic particles are the common name for plastic particles. They are the raw materials for storing, transporting and processing plastics in the form of semi-finished products. They are widely used in the manufacture of plastic products. In the production and processing of plastic particles, how to reduce the residual low molecular weight compounds in modified plastic particles and reduce the odor of particles is a focus of attention in the industrial production of modified plastics. In the prior art, in order to reduce the residual low-emission substances on modified plastic particles, it is generally necessary to degas and dry the plastic particles through the corresponding degassing and drying device. At the same time, it can also effectively remove moisture from the plastic particles to keep them dry, which is convenient for the subsequent processing of plastic products.

[0004] Most of the existing plastic particle degassing and drying devices have a single structure. During the degassing process, the plastic particles are easily piled up together, resulting in the plastic particles being unable to fully contact with the high-temperature steam, thereby affecting the degassing effect of the plastic particles. During the drying process, the plastic particles are also easily piled up, resulting in reduced efficiency of heating and drying and cooling, which is inconvenient to use. In addition, the harmful gases and dust generated during the entire degassing and drying process cannot be removed, which is easy to pollute the environment and is not environmentally friendly. Therefore, the present invention proposes a plastic particle degassing and drying device to solve the problems existing in the prior art. Summary of the invention
