Description

Technical Field

[0001] The invention relates to the technical field of granule drying, in particular to a collecting and drying device for medical PVC granules. Background Art

[0002] PVC granules are a kind of synthetic material, the main component of which is polyvinyl chloride. They have good plasticity, corrosion resistance and insulation. They are often used in the manufacture and production of building materials, coatings, doors and windows, pipes and other products. The medical plastics industry has attracted much attention for its high added value, high growth rate and broad market potential. By adopting new plastic materials, medical devices can be made safer and more environmentally friendly. Medical PVC granules need to be molten into strips by an extruder during production. The extruded plastic strips are transported to a pelletizer after water cooling. The pellets after pelletizing need to be dried by a collection and drying device and then stored. When general pellet dryers on the market dry the pellets, due to the concentrated accumulation of pellets, the PVC pellets are not fully dried during the drying process. Some pellets at the bottom are often difficult to dry, the drying efficiency is low, and the drying time is very long. In this regard, we propose a collection and drying device for medical PVC pellets. Summary of the invention
