Segmental Backwash Screen Changer: Solving All Types of Melt Filtration Challenges
The Zhengzhou Batte Sector-Type Backflush Screen Changer is a professional melt filtration device custom-designed for demanding high-pressure, high-temperature operating conditions. It can withstand operating pressures of up to 25 MPa and temperatures of up to 350°C, making it perfectly suited for a wide range of complex and harsh melt production environments. Equipped with an electric motor-driven transmission system, the device operates smoothly and reliably, making it the ideal solution for continuous extrusion production applications.
The core advantage of the sector-type backflush screen changer lies in its ability to ensure stable, uninterrupted operation throughout the entire production process: the screen is designed in a sector-shaped configuration, and during the fully automated filtration process, the area of the continuously active filtration zone remains constant, ensuring long-term stability in operating pressure and temperature. Thanks to an optimized internal flow channel design and precision sealing structure, the equipment significantly reduces material residence time, thereby fundamentally lowering the risk of melt degradation and carbonization. This effectively stabilizes output quality and improves product yield. Additionally, the compact design minimizes installation space requirements and reduces energy consumption during operation, helping manufacturers achieve energy savings, lower costs, and increased efficiency.
Its most prominent feature is the highly efficient and stable backflush system: the backflush mechanism is located within the post-filter pipeline. Driven by a hydraulic system, it uses pressure pulses to draw a small amount of clean material and inject it into the filter screen, efficiently removing impurities. Since the cleaning area per cycle is small and the process occurs without pressure fluctuations, it does not interfere with the normal continuous production rhythm at all. Currently, the sector-type backflush screen changer is widely used in plastic extrusion, chemical fiber spinning, and various industrial melt filtration applications, providing stable, efficient, and energy-efficient professional melt filtration solutions for a wide range of production lines.
