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
品等に気泡が生じるから、機内のガスを抜くこと
が重要である。従来、押出機等からガスを抜く方

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 occur 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.
本考案の目的は、ロータ長が短い場合にも実施
することのできる、押出機等のガス抜き装置を提
供することにある。 An object of the present invention is to provide a degassing device such as an extruder that can be used even when the rotor length is short.
以下、本考案の実施例を図面に基づいて説明す

is pivotally supported within the double cylinder fixed container 3, and is rotationally driven in a predetermined direction by a power device (not shown). A multi-axis cylindrical body 5 having a flange 4 is attached to the upper center of the double-tube fixed container 3. This multi-axis cylindrical body 5 has cylindrical parts 6...6 of three or more axes, five axes in the embodiment, connected in series while communicating with each other, and each cylindrical part 6...6 communicates with the fixed container 3, and its cylindrical parts 6...6 are connected in series. The series direction coincides with the axial direction of the biaxial rotors 1 and 2. Further, the lower end of this polyaxial cylinder 5 communicates with the fixed container 3, and a cavity 7 is formed in the upper part thereof and communicates with an exhaust pipe 8. The exhaust pipe 8 communicates with a vacuum pump (not shown). . Each cylindrical portion 6...6 is provided with a screw 9...9, respectively, as shown in FIG. The screw shafts are driven to rotate in opposite directions by a motor (not shown), and each screw is rotated in a direction that returns the material into the stationary container. In the figure, 12 is a bearing, and 13 is a packing material.

される。 In such a device, the gas contained in the material is sucked out from the exhaust pipe 8 through the gap between the multi-axis cylinder 6 and the screw 9, but the material is blocked by the crest of the screw and does not leak. Even some leakage is returned to the fixed container by the rotation of the screw.

ある。 According to the present invention, since the serial direction of the multi-axis cylinders is arranged in the same direction as the axial direction of the two-axis rotor, the gas generated in each part of the two-axis rotor is directed to either one of the multi-axis cylinders. It is exhausted through the system and does not remain in the exhaust port of the extruder, etc. Furthermore, since the peaks of each screw overlap, there is a function to prevent material leakage even when the shaft is not driven to rotate.
