Application, Characteristics, and Configuration of Single Board Fast Screen Swapper

Single plate screen changer is commonly referred to as single plate fast screen changer. This type of screen changer has been widely used in the market due to its simple structure, high cost-effectiveness, wide range of use, and the characteristics of non-stop, no material leakage, smooth flow channels, and simple operation.

The structure of the single plate screen changer is simple and convenient to connect, and it can be used in direct connection with different specifications of single screw extruders, double screw extruders, and reaction kettles, simplifying the material flow channel.

The single plate screen changer adopts a pressure activated sealing device, which meets the extrusion production of almost all thermal plastics and the polymerization production of polymer chemical raw materials. The porous support plate after rheological optimization of the material effectively reduces the shear of the melt during the extrusion process. Special materials can optimize the porous plate structure based on material characteristics and process requirements, effectively improving filtration permeability and filtration quality.

This type of screen changer can achieve non-stop screen changing during the screen changing process, achieving the effect of no material leakage. Equipped with suitable hydraulic stations according to the size of the screen changer, the fast screen changing time is basically controlled within 2-5 seconds.

The commonly used heating methods for single board mesh exchangers are external heating plates or heating coils, built-in heating tubes, or comprehensive heating methods. They can also be customized for heating medium according to requirements, which is energy-saving and efficient. For corrosive materials, anti-corrosion treatment can be applied or anti-corrosion materials can be used for processing.

The standard configuration of a single plate screen changer is three major components: the main body of the screen changer, the energy storage hydraulic pump station, and the electrical control cabinet. Users can choose the configuration according to their needs.

When selecting a screen changer, it is necessary to comprehensively consider various factors such as applicable output, material viscosity, material composition, filtration accuracy (filter mesh), equipment pressure, etc. The specific selection depends on the actual process parameter design.
