A single-plate hydraulic screen changer is a device used in production processes such as plastic extrusion to enable rapid screen replacement, maintaining continuous production without shutdown. Below is a detailed introduction:
Structural Components
The single-plate hydraulic screen changer primarily consists of the main body, reciprocating slide plate, hydraulic cylinder, removable perforated plate, and centralized wiring protection device.
Working Principle
Typically featuring a dual-station design, the slide plate incorporates two filter channels with embedded porous filter plates. When a screen change is required, the hydraulic system drives the slide plate to move, positioning the spare filter screen into the working station to replace the clogged one. This entire process takes only a few seconds, enabling non-stop screen changes.
Features
Rapid Screen Change: Equipped with a pressure accumulator, the dual-station system achieves screen changes in ≤2 seconds, minimizing production downtime.
Reliable Sealing: Pressure-driven sealing technology with automatic gap compensation prevents melt leakage, ensuring stable production.
Compact Design: Features an integrated structure with a small footprint and short flow path, offering strong adaptability for use with extruders of various standards.
Easy Maintenance: Simple core components eliminate complex multi-station switching mechanisms, facilitating routine disassembly, cleaning, and part replacement.
Temperature and Pressure Resistance: Operates stably under pressures of 25-30MPa and temperatures up to 300°C, meeting processing requirements for diverse thermoplastics.
Application Areas
Suitable for various thermoplastic production processes including sheet, plate, pipe, film coating, blown film, wire, cable, profile, and pelletizing.
Technical Parameters
Filter Diameter: Common specifications include ￠70-￠400mm, with multiple options available.
Throughput: Varies by model. For example, the ZB-SSP-A-70 model achieves 75-200kg/h.
Zhengzhou Batte Melt Pump Co., Ltd.'s single-plate dual-station hydraulic screen changer features an integrated structure with compact dimensions, short flow paths, and reliable sealing. Filter areas range from 50mm to 360mm in diameter, compatible with extruders of various standards.
