本考案は押出機、連続混練機のガス抜き装置に
関する。[Detailed Description of the Invention] The present invention relates to a degassing device for an extruder or a continuous kneader.
押出機や連続混練機内の材料にガスが発生し、
或いはガスが混入していると、プラスチツク成形

法によれば、ロータの全長が長くなる欠点があ
る。 Gas is generated in the material inside the extruder or continuous kneading machine,
Alternatively, if gas is mixed in, bubbles will form in plastic molded products, so it is important to vent the gas inside the machine. Conventionally, as a method for removing gas from an extruder, etc., as shown in Fig. 1, the feed angle of the screw of the rotor is divided into a low speed section a, a high speed section b, and a low speed section c.
By forming a blank part of the material in the high-speed section b and connecting it to the vacuum system by providing an exhaust pipe d in the blank part, the material is not sucked.
A device is known that sucks out only gas components contained in a material. However, this degassing method has the disadvantage that the total length of the rotor becomes longer.

Ａ，８Ａの外周に沿つている。 One end of the degassing cylinder 4 opens into the fixed container 2, and the other end is connected to a reduced pressure exhaust system (not shown) via an exhaust pipe 5.
is connected to. Three screw shafts 6, 7, 8 are supported in parallel to each other by bearings within the cylinder 4.
A helical screw 6A, 7A, 8A is formed on each shaft. All screws are in the same direction,
For example, it is a right-handed screw, and the thickness of the crest is pitch P.
It is smaller than 1/3 of the screw size, and the ridges of all three screws overlap at the center of the three axes. Cylindrical body 4
As shown in FIG. 4, the cross-sectional shape of the outer circumferential part of the screw is such that the inner surface thereof is the peak part 6A, 7 of the screw.
It is along the outer periphery of A, 8A.

戻される。 When this device is used, the three screw shafts 6, 7, and 8 are rotated in a direction to push the material into the fixed container 2, and the discharge pipe 5 is communicated with the reduced pressure exhaust system. The gas contained in the material is suctioned out from the discharge pipe 5 through the gap in the cylinder, but the material is blocked by the helical peak and does not leak, and even if it leaks a little, it is removed by the rotation of the screw. Returned to fixed container.
