Recycling plastic screen changer
The plastic recycling screen changer plays a pivotal role in the process of recycling and pelletizing waste plastics. Below is a detailed explanation of the plastic recycling screen changer:
1. Definition and Function
The plastic recycling screen changer is primarily used in waste plastic recycling and pelletizing production lines. It employs filtration and screen-changing mechanisms to remove impurities from the plastic melt, thereby ensuring product quality and maintaining production continuity.
2. Types and Characteristics
Types
Dual-Column Large Filter Cartridge Screen Changer: Made from high-quality alloy steel and undergoing multiple specialized processes, this screen changer features a dual-screen, dual-channel design. It is suitable for production processes such as recycling and pelletizing, as well as for the manufacture of cast films, sheets, and plates.
Automatic Flushing Screen Changer: Equipped with automatic filter cleaning capabilities, this screen changer significantly reduces the frequency of screen changes, avoiding frequent downtime and making it ideal for waste plastic recycling applications.
Characteristics
Dual Screens Operating Simultaneously: The dual-screen, dual-channel design ensures that both screens operate concurrently when not being replaced, and switch alternately during screen changes, maintaining production continuity.
No-Downtime Screen Changes: With a stabilizing structure, the screen change process can be carried out without halting production or disrupting material flow, meeting the needs for high-capacity, high-quality production.
Automatic Cleaning Function: The automatic flushing screen changer utilizes the movement of a backflush plunger to automatically clean the filter screens, extending the intervals between screen changes.
Safety and Reliability: Featuring rigid sealing structures, it ensures no leaks. Additionally, it incorporates automatic alarm and control systems to maintain safe and stable operation.
