Description

Technical Field

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

[0002] Plastic pellets, also known as plastic particles or plastic raw materials, are the basic raw materials for producing plastic products. They are usually thermoplastic plastics that can soften when heated and can repeat this process multiple times.

[0003] Plastic pellets are usually small particles in round or irregular shapes, made of specific plastic resins, and can be used in various plastic processing techniques such as injection molding, extrusion, blow molding, calendering, etc.

[0004] There are many types of plastic pellets, and the common ones include:

[0005] Polyethylene (PE): A common thermoplastic with good low-temperature resistance and chemical stability, often used for making plastic bags, plastic films, plastic barrels, pipes, etc.

[0006] Polypropylene (PP): Another commonly used thermoplastic with high strength and heat resistance, often used for making automotive parts, household appliances, food packaging containers, etc.

[0007] Polyvinyl chloride (PVC): A versatile plastic with good physical and mechanical properties and good chemical resistance, widely used in building materials, packaging materials, wire and cable, etc.

[0008] Polystyrene (PS): With low cost and good processing performance, often used for making foam plastics, food packaging materials, toys, etc.

[0009] Polycarbonate (PC): A high-performance engineering plastic with excellent impact strength and transparency, widely used in automotive parts, electronic and electrical fields, CD manufacturing, etc.

[0010] Currently, after the plastic pellets are cut, they are generally in a wet state. Since in the previous process, after extrusion, they need to pass through a cold water tank for cooling and shaping, and then the strip-shaped plastic strips are cut into plastic pellets. However, during the subsequent screening of the plastic pellets, they need to be dried to prevent them from adhering to the screening mesh and affecting the screening effect. Since there is still some water residue on the plastic pellets at this time, a drying operation is required to ensure the normal progress of the screening work. Content of the Utility Model

[0017] Specifically, a water baffle is arranged inside the square cylinder.
