Abstract

A device for filtering high-viscosity liquids, especially melts of thermoplastic synthetic materials, which is preferably coupled to an extrusion press, consisting of a box with central inlets and outlets, a bifurcation channel between the outlet and inlet, and at least two filters arranged in this channel in parallel and in a replaceable way, each filter being assigned replaceable filter cups, as well as switchable shut-off valves on the inlet and warm side and an air purge line, characterized in that the branch channel is made up of an annular pipe on the inlet side, common to the inlet valves, and by an annular pipe on the outlet side, common to the outlet valves, the annular pipes having laterally coupled torna pipes ; because the inlet valve and the outlet valve are arranged in such a way in the annular pipes that evacuation extensions are movable in the laterally coupled intake pipes, and because the filter vessels, provided with separate inlet and hermetically sealed outlets, they are detachably connected to the intake pipes attached to the sides.
