This utility model discloses a vacuum extraction device for a twin-screw extruder, which comprises a barrel. An exhaust chamber is fixedly mounted on the top of the barrel through bolts, a metal water pipe is welded at one end of the exhaust chamber, a pressure gauge is screwed on the surface of the metal water pipe, and a ball valve is screwed at one end of the metal water pipe. A first metal hose is screwed at one end of the ball valve, a water tank is screwed at one end of the first metal hose, an L-shaped metal water pipe is welded on the top of the water tank, a second filter is screwed at one end of the L-shaped metal water pipe, a second metal hose is screwed at one end of the second filter, and a vacuum pump is screwed at one end of the second metal hose. By installing the pressure gauge and the ball valve on the metal water pipe, the suction force of the exhaust chamber can be observed and adjusted according to requirements; by installing the second filter on the top of the water tank, the erosion of volatile substances on the impeller of the vacuum pump can be reduced, which greatly prolongs the service life of the vacuum pump and reduces air pollution.
