Most plastic materials contain impurities, and because polymers are continuous in production, large-particle materials and impurities are blocked on a filter screen and gradually accumulated as a result of continuous filtration, meshes are blocked after the plastic materials are used for a period of time, the flow rate is reduced, the pressure is increased, and the filter screen needs to be replaced when the yield is influenced.

In the prior art, the screen changer is used for screen changing, and the screen changer is a manual or automatic switching device comprising one or more filter screens and is used for filtering foreign particles and impurities when a plasticizing material flow filters the screens. The screen is supported by an alloy perforated plate mounted on a plate or column type carrier which can be moved to switch between a system operating position and an off-line non-operating position. The screen changer may be installed on any new or existing extruder, melt pump, reactor or other extrusion line.

The existing common screen changer adopts a single-column structure, and the fluctuation-free screen changer adopts a double-column structure. When the screen of the screen changer with the double-column structure is changed, the pressure fluctuation can still be caused due to the great reduction of the filtering area.
