本発明は粉粒状合成重合体の連続固相重合装置
に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous solid phase polymerization apparatus for powdery synthetic polymers.
一般に産業資材用に使用されるポリエステル糸
は高強力を要求されるため重合度を高くする必要
があり、このため溶融重合で得られた所定重合度
のポリエステルの粉粒体を更に固相重合すること
によつて高重合度に反応せしめている。 Generally, polyester threads used for industrial materials require high strength, so it is necessary to increase the degree of polymerization. Therefore, polyester powder with a specified degree of polymerization obtained by melt polymerization is further solid-phase polymerized. In particular, the reaction has a high degree of polymerization.

質のバラツキが生じる欠点がある。 Conventionally, a tumbler-type apparatus has been mainly used for solid-phase polymerization of powdered or granular materials of synthetic polymers. However, since this type of apparatus is a batch type, the capacity is small and the reaction time is long, the operation is cumbersome and time consuming, and the quality varies from batch to batch.

In an apparatus for continuously polymerizing powdery synthetic polymers in a heated vacuum, a rotating shaft with screw blades is disposed in a horizontal reaction vessel, and a large number of small holes are bored in the screw blade, and screw grooves are formed in the screw blade. It is characterized by having an axial rake blade.

The figure is a schematic sectional view showing an embodiment of the present invention, and FIGS. 2 and 3 are a front view and a side view showing the screw portion of FIG. 1. In the figure, reference numeral 1 denotes a cylindrical reactor body surrounded by a jacket 2 for a heating medium, and a supply nozzle 3 is provided at the upper part of the front end, and a discharge nozzle 4 is provided at the lower part of the rear end. A rotary shaft 5 having screw blades 6 in the axial direction is rotatably provided inside the main body 1. The screw blade 6 has its outer periphery close to or in contact with the main body 1, and the entire surface of the screw blade 6 has many small holes 7 (in the figure, 1
(only part shown) is perforated. Furthermore, a plate-shaped scraping blade 8 that crosses the screw groove 9 is installed on the outer peripheral portion of the screw blade 6 in the axial direction. 10 is a suction nozzle connected to a vacuum generator such as a steam ejector, and 11 is a drive motor.

る。 In the apparatus constructed as described above, a particulate synthetic polymer (hereinafter referred to as "chip") having a predetermined degree of polymerization is continuously fed into the main body through the supply nozzle 3. The inside of the main body 1 is heated to a constant temperature (150 DEG -230 DEG C.) by a jacket 2, and maintained at a predetermined high degree of vacuum (0.5 to 2 Torr) through a suction nozzle 10. The chips fed into the main body 1 advance in the direction of the discharge nozzle 4 by the rotation of the screw blade 6, but since the screw blade 6 is provided with a large number of small holes 7, some of the chips advance while others remain. This results in more mixing of the chips and a smaller overall feed. Further, since a scraping blade 8 is provided between the facing screw blades 6, a portion of the chip is scooped up and falls again during approximately 1/4 to 1/2 rotation. During this time, the chips that are scooped up and fall are repeated at almost the same location (same chamber), and there is no advancement of the chips, so the chips are scooped up and dropped into the same screw groove 9.
Stirring within the container is performed efficiently, resulting in good mixing and uniformity. Furthermore, the chips are made into a thin layer by the scraping blades 8 and the surface area as a whole is increased, so that the diffusion of moisture and the like is improved and the reaction rate is further increased. While being stirred and mixed in this way, the chips gradually move to the discharge nozzle 4 side, and during this time, the degree of polymerization gradually increases as the polymerization reaction progresses, and after several hours, for example 4 to 8 hours, they reach the target at the discharge nozzle 4 position. It reaches a degree of polymerization and is continuously discharged from there.
尚、掻き上げ翼８は回転方向側に多少傾斜させ

い。又チツプの送りを更に遅くしかつ混合をよく
するために第４図に示す如く第３図のスクリユー
羽根８の外周に切欠７′を設けてもよい。 Incidentally, it is preferable that the scooping blades 8 be inclined somewhat in the direction of rotation so that the chips can be easily scooped up and the chips that have been scooped up can fall rather quickly. Further, the small holes 7 of the screw blade 6 may be of an appropriate size and number in view of the passage of chips and the gas flow (vacuum suction) between the screw grooves 9. Also, in order to further slow down the feeding of the chips and improve mixing, a notch 7' may be provided on the outer periphery of the screw blade 8 of FIG. 3, as shown in FIG. 4.
以上に説明の如く、本発明によれば混合、表面
更新性等が極めてよくかつチツプ表面積が大きく
とれるので反応時間が短かく均一かつ優れた品質
の製品チツプを安定して得ることが可能となる。 As explained above, according to the present invention, mixing, surface renewability, etc. are extremely good, and a large chip surface area can be obtained, making it possible to stably obtain product chips of uniform and excellent quality with a short reaction time. .
