Spinning quench chamber having a conical flow director
Abstract
Abstract A CYLINDRICAL CHIMMEY USED FOR QUENCHING SYNTHETIC FILAMENTS AFTER THEY ARE EXTRUDED FROM A SPINNERET IS DIVIDED INTO CONCENTRIC CYLINDRICAL PLENUM AND QUENCHING CHAMBERS BY MEANS OF A CYLINDRICAL FORMATIONS MEMBER COMPRISED OF AT LEAST FIVE LAYERS OF FINE MESH SCREENS SPACED FROM EACH OTHER A SPECIFIED DISTANCE TO IMPROVE QUENCH MEDIUM DISTRIBUTION FROM THE PLENUM INTO THE QUENCH CHAMBER. A CONE SHAPED FLOW DIRECTOR EXTENDS FROM THE SPINNERET COAXIALLY INTO THE QUENCHING CHAM- BER. A FLOW RESTRICTOR AT THE EXIT END OF THE QUENCH CHAMBER FORMS A PARTIAL SEAL WITH THE FILAMENT BUNDLE DIRECTING THE AIR FLOW THROUGH THE BUNDLE FOR MORE EFFICIENT COOLING. A GUIDE POSITIONED BELOW THE CHIMNEY QUENCH CHAMBER ENCOMPASSING THE FILAMENTS SERVES TO STABILIZE THE THREADLINE AND IS VERTICALLY MOABLE TO VARY THE FILAMENT BUNDLE SIZE AT THE POINT IT PASSES THROUGH THE FLOW RESTRICTOR TO VARY THE SEALING EFFECT OF THE BUNDLE.
