Abstract | According to the present invention, a twin screw extruder is continuously operated even during filter replacement by using a pair of filters. This continuous extrusion device based on a twin screw extruder has a pair of filters (6, 6a) provided to a degassing device (5), and a partition valve (24) having a valve (34) for establishing or terminating communication between the filters (6, 6a) and the screw hole (16) of a cylinder (1). When the first filter (6) is being replaced, degassing is performed using the other, second filter (6a). The twin screw extruder is continuously operated even during filter (6, 6a) replacement.
Selon la présente invention, une extrudeuse à double vis fonctionne en continu même lors du remplacement de filtre à l'aide d'une paire de filtres. Ce dispositif d'extrusion continue basé sur une extrudeuse à double vis possède une paire de filtres (6, 6a) situés sur un dispositif de dégazage (5), et une soupape de séparation (24) possédant une soupape (34) pour établir ou mettre fin à une communication entre les filtres (6, 6a) et le trou de vis (16) d'un cylindre (1). Lorsque le premier filtre (6) est remplacé, le dégazage est réalisé à l'aide de l'autre second filtre (6a). L'extrudeuse à double vis fonctionne en continu même pendant le remplacement du filtre (6, 6a). |
