The present utility model discloses an anti-material-leakage device for a twin-screw extruder used for processing polyarylene sulfide materials, comprising an extrusion barrel and an exhaust pipe fixedly communicated with the top of the extrusion barrel. A plurality of baffles are symmetrically and fixedly connected to the bottom of the inner wall of the exhaust pipe, an anti-material-leakage mechanism matched with the baffles is installed on the top of the exhaust pipe, a second air pipe is fixedly communicated with one end of the upper surface of the exhaust pipe, and a forced exhaust mechanism is installed on the other end of the upper surface of the exhaust pipe. In the present utility model, through the arranged anti-material-leakage mechanism and baffles, when part of the material flows toward the exhaust pipe along with the gas and is finally discharged from the second air pipe, most of the material will be blocked by the baffles due to the staggered arrangement of the baffles and cannot easily continue to flow upward. Meanwhile, a spiral blade driven by a motor can re-extrude the overflowed material back into the extrusion barrel, so that the material will not leak outward from the exhaust pipe.
