Description

Technical Field

[0001] The utility model relates to the technical field of melting devices, in particular to a melting device for plastic production. Background Art

[0002] Plastic particles can be roughly divided into more than 200 types, which can be subdivided into thousands of types, and dozens of common types. In daily life, plastic particles can be used to make various plastic bags, buckets, basins, toys, furniture, stationery and other daily necessities and plastic products. In terms of building materials, they can be used to build various building components, building tools, plastic doors and windows, and plaster buckets. Plastic particles play a vital role in life. In the current production process of plastic particles, the raw materials must first be melted using a melting device. Melting refers to the process in which the kinetic energy of the thermal motion of molecules increases when the temperature rises, resulting in the destruction of crystallization, and the substance changes from the crystal phase to the liquid phase; it is a first-order phase transition, with an increase in thermal enthalpy, entropy and volume. The melted plastic particles can be easily shaped.

The plastic processing and melting device has more uniform melting, reduces the impurity content in the molten plastic, has high melting efficiency, and improves the production efficiency of the plastic.

[0004] At present, there are still some shortcomings in a plastic processing melting device. For example, when the plastic production raw materials are melted, plasticizers, colorants, etc. are added, resulting in the waste gas produced during melting having certain toxicity, which is directly discharged and affects the health of the surrounding workers. Therefore, how to design a melting device for plastic production has become a problem that we currently need to solve. Utility Model Content
