The invention relates to a device for filtering a fluid, in particular a liquefied plastic, with a housing with backflush channel and screen carrier and filter element whereby, in order to accelerate and improve the backflush effect, one or more displacement cylinders are provided that guide material removed from the production at adjustable high pressure and speed to the screen to be cleaned from the clean screen side to the dirty screen side, whereby an additional pressure generator ensures constant process pressure.

Device and method for filtering a fluid, in particular for plastics processing plants

The invention relates to an arrangement and a device for filtering a fluid, particularly for plastic processing plants, wherein the pressure drop, or the flow rate reduction, created by the withdrawal of material from the process is sensitively balanced in that pressure constancy and flow rate constancy are achieved at the discharge duct ().

Device for filtering a fluid, particularly for plastic processing plants

A device for filtering a liquid synthetic material. The device has a housing, a feed channel, a discharge channel, and backflow channels. The feed duct is subdivided into split-feed channels (A,B). The cross-section of the orifice of the split-feed channels, where they open into the filter chambers, is smaller than the normal cross-section of the feed channels.
