Fan-shaped rotary screenless motorized screen changer
The fan-shaped rotary screen changer is a “filtration versatile” for polymer processing (especially for extrusion systems), designed to solve the contradiction between screen replacement and continuous operation in production, and can easily cope with high-frequency screen changes, frequent color changes and other scenarios, with its core function focusing on high efficiency filtration and guaranteeing production continuity.
Its working principle is hidden in the “rotating disk” - there are several filter slots on the disk, when rotating, the new filter screen slowly enters the melt flow channel, and the old filter screen is synchronously removed, forming a "continuous filtration mode of changing the screen while producing. "This creates a continuous filtration pattern. This design keeps the filtration area constant, avoids pressure fluctuations that are common with conventional screen changes, and keeps the production rhythm steady.
The technical advantages are even more outstanding. Constant pressure stability is the key, constant filtration area so that the melt pressure fluctuations are small, the product parameters can be maintained consistently; continuous production without downtime, equipment utilization can be increased by 30% -50%; change the screen speed is also fast, the modular design allows the replacement of the time to shrink to the traditional way of 1/5, and it is a strong adaptability, frequent change of material, color can be coped with, multi-variety production is also a no-brainer.
It can be used in a wide range of application scenarios, including the extrusion process to filter impurities in the melt and enhance the transparency of the products; the recycling field to remove impurities in the recycled materials and ensure the performance of the recycled products; and even the high-pressure precision extrusion line that requires ultra-clean filtration, it is also capable of enhancing the productivity and product quality of the practical equipment.
