Fully-automatic, pressure-constant, permanent process consistency-
With regard to achievable product quality, economic efficiency and in terms of operator and maintenance friendliness, the RSFgenius offers unrivalled possibilities. This fully-automatic and pressure-constant filtration system can be used in virtually any application, for automation of the production process and for the manufacture of a high quality final product. The RSFgenius is particularly well suited for ultra-fine filtration, the filtration of thermally-sensitive melts and the filtration of materials with a high contamination level.
The advantages of the RSFgenius Filtration System-
Mode of operation
A high pressure segmental backflushing system purges the screen packs clean, shortly before their re-entry into the melt channel. A small, measured „shot“ of filtered polymer is taken from the „clean“ (filtered) side of the screen changer and injected with an adjustable pressure of approx. 30 – 80 bar backwards across the screen pack. The backflush is then ejected through the screen changer inlet block to the outside. Only a small segment (approx. 1 %) of the screen area is cleaned at one time. A defined quantity of material delivers a high energy cleaning impulse.
The filter disk – on which the screen cavities are located in a ring pattern – is completely encapsulated by the two filter blocks. Screens can be inserted into the cavities by opening a small hatch door giving access to the cavities. The production process is not disturbed by the screen change procedure. Thanks to the modular design of this filtration system, it is possible to replace the few wearing parts (such as heater elements and bearing bushings) during operation. Continuous production over many years is thus made possible.
