続縮重合に好適な連続処理方法及び装置に関するもので
ある。The present invention relates to a continuous processing apparatus for highly viscous substances, and more particularly to a continuous processing method and apparatus suitable for continuous polycondensation of polyethylene terephthalate, polycarbonate and the like. .
一般に、高粘性物質の混練、反応等の連続処理において

軸２０の表面に一旦付着した液２１は、撹拌翼２２に付
着した液に比べて液中での速度が小さく、せん断力が弱
いため更新され難く、付着したままで共回りする。Generally, in continuous processing such as kneading and reaction of highly viscous substances, the dead space in the device is reduced as much as possible,
Moreover, an operation similar to the extrusion flow is required. For this reason, various types have been devised in which a horizontally long cylindrical container is used and two rotary shafts with stirring blades are installed in the longitudinal direction. For example, as shown in Japanese Examined Patent Publication (Kokoku) No. 52-29019, there is a structure in which paddle blades are arranged in multiple stages and the inner surface of the container can be scraped off to reduce the dead space. However, as shown in FIG. When the processing liquid has a high viscosity of several thousand poises or more, the high-viscosity liquid 21 adhering to the surface of the rotating shaft 20 co-rotates with the surface of the rotating shaft 20 and causes a problem such as scaling. . That is, the liquid 21 once adhered to the surface of the rotary shaft 20 has a smaller speed in the liquid than the liquid adhered to the stirring blade 22 and is difficult to be renewed due to a weak shearing force, and co-rotates with the liquid adhered.

伴って撹拌翼２３と共に動くが、板表面近くに一旦付着
した高粘性液は、撹拌翼２３の先端以外ではせん断力が
小さいため、撹拌翼２３表面に付着して共回りする。Therefore, an attempt was made to eliminate this rotating shaft 20 to reduce co-rotation, and as suggested in Japanese Patent Publication No. 49-40732, the rotating shaft 20 was formed by connecting the outer peripheral portion of a partially hollowed disk. There is something I lost. This eliminates co-rotation on the rotary shaft 20, but the next problem is the first problem.
As shown in FIG. 4, the highly viscous liquid 24 adhering to the surface of the plate-shaped stirring blade 23 is hard to flow and co-rotates with the stirring blade 23 to cause scaling and the like. That is, when an object having a flat surface such as a plate is rotated in a high-viscosity liquid, the high-viscosity liquid 24 moves together with the stirring blade 23 as the stirring blade 23 rotates as shown in FIG. Since the high-viscosity liquid once attached to the above has a small shearing force except at the tip of the stirring blade 23, it adheres to the surface of the stirring blade 23 and co-rotates therewith.
上述したように、回転軸表面や板状撹拌翼表面に付着し
た高粘性液は、熱劣化などにより被処理液の品質を低下
させる原因となる。As described above, the highly viscous liquid attached to the surface of the rotating shaft or the surface of the plate-shaped stirring blade causes deterioration of the quality of the liquid to be treated due to heat deterioration or the like.
上記従来技術は、被処理液の付着や共回りについて配慮

粘性液は滞留し、熱劣化などにより、被処理液の品質が
低下するという不具合点があった。The above-mentioned conventional technology does not consider the adhesion and co-rotation of the liquid to be treated, and the highly viscous liquid adhered to the surface of the rotating shaft and the surface of the stirring blade accumulates, and the quality of the liquid to be treated deteriorates due to thermal deterioration. There was a problem that it did.

る。The purpose of the above is to focus on the fact that the problem with the conventional device is co-rotation of the high-viscosity liquid to the rotating shaft and the surface of the plate-shaped stirring blade, and to construct the stirring blade without the rotating shaft and the plate-shaped member. Is achieved by Further, it is achieved by using a stirring blade made of an environmental member having good mixing and extrusion flow characteristics.

Furthermore, since these stirring actions are performed by the stirring blade made of an annular member, it is possible to sufficiently reduce the dead space, and by this, the liquid on the surface of the rotating shaft or the surface of the plate-shaped stirring blade, which has been a problem in the past, can be reduced. Adhesion and co-rotation can be almost eliminated.
