た高粘度液処理装置に関するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-viscosity liquid processing apparatus, and more particularly to a high-viscosity liquid processing apparatus having two horizontal shafts.

は入口から出口に進行する位置によって反応度合が変わ
る特徴をもっている。In general, this type of high-viscosity liquid processing apparatus is roughly classified into a continuous type and a batch type (batch type). Among these, the continuous type high-viscosity liquid processing apparatus is provided on one side in the longitudinal direction of the casing. The raw material to be processed is charged from the provided inlet and flows (so-called piston flow) while increasing the reactivity, etc. before proceeding to the outlet on the other side, and after the desired processing is obtained, is discharged from the outlet. (JP-B-47-27179, JP-B-51-45559, JP-B-54-5805, JP-B-61-59173, and JP-B-6
2-50179, etc.). Therefore, such a continuous system has a feature that the degree of reaction varies depending on the position where the reaction proceeds from the inlet to the outlet.

たことが望ましい特徴をもっている。On the other hand, a batch type horizontal high-viscosity liquid processing apparatus calculates a raw material to be processed once, charges the raw material into a casing, discharges the raw material after a desired processing is obtained, and then newly prepares the next raw material. It is a charging method (refer to JP-A-49-73759). Therefore, in such a batch system, the degree of reaction changes as the processing time elapses, and it is desirable that a uniform reaction be simultaneously performed at any position in the casing during a certain processing time.

させるものはなかった。In these high-viscosity liquid treatment devices, regardless of the continuous system or batch system, a uniform shearing / stirring function is combined with a circulation or unidirectional liquid feeding function, and a scraping function between stirring blades (self-cleaning function). ) Further, a liquid surface renewal function is required, but in the conventional high-viscosity liquid processing apparatus, these functions, in particular, the shearing / stirring function and the liquid sending function are made as simple as possible in a circle. Nothing was exhibited simultaneously by the plate-shaped stirring blades.

The blades (8, 9) (10, 11) and the scraping rods 7, 12 rotate relative to each other so as to intersect and bite each other as shown in section A. As a result, the fan blades 5 of the stirring blades 4 for low speed, the fan blades 10 of the stirring blades 8 and 9 for high speed, and the shear blades 5a, 10a, 11 of the small blades 11 are obtained.
As a crosses each other at different rotation speeds, the high-viscosity liquid is pushed toward the raised portion 1a of the casing 1 while undergoing strong shearing / stirring, that is, the high-viscosity liquid is stirred so that the high-viscosity liquid on the liquid free surface is always replaced. After kneading, the casing 1
Is sent to both side walls parallel to the rotation axis (2, 3). At that time, the high-viscosity liquid is firstly dispersed by the slopes of the blades 5, 10, and 11.
In the drawing, the liquid is fed in the directions of arrows a and c, and circulates in the casing 1 in a single direction of arrows a, b ', c and b. In addition, the high-viscosity liquid adhering to the inner peripheral surface of the casing 1 is scraped off by the scraping rods 7 and 12 arranged in a spiral shape of the same lead and is subjected to a liquid sending action while performing self-cleaning. Will help. When the scraping rods 7 and 12 are exposed from the high-viscosity liquid, they lift the high-viscosity liquid, so that a drooping thin film is formed, whereby the gas-liquid contact surface is enlarged and the degassing property is improved.

続的に撹拌・混練されながら進むことになる。That is, the low-speed shaft 2 has a fan-shaped blade 5A substantially similar to the low-speed stirring blade 4 shown in the first embodiment.
4A, and the high-speed shaft 3 employs a high-speed stirring blade 14 in which a fan-shaped blade 10A similar to the fan-shaped blade 10 of the first embodiment shown in FIG. 5 is skewed, and The direction of the inclined surface of the fan blade 5A of the low-speed stirring blade A and the direction of the inclined surface of the fan blade 10A of the high-speed stirring blade 14 are the same.
Further, at the outer peripheral end of the fan-shaped blade 5A of the low-speed stirring blade 4A,
As in the first embodiment, the scraping rods 15 are arranged in a continuous spiral shape. On the other hand, the high-speed stirring blades 14 are sequentially mounted on the high-speed shaft 3 with a phase difference of 90 °, and these high-speed stirring blades 14 are scraped to the outer peripheral edge on the leading side when the fan-shaped blade 10A rotates. One end of the scraping rod 16 is fixed, and the other end of the scraping rod 16 is fixed to the outer peripheral end on the leading side of another adjacent fan blade 10A, so that the scraping rod 16 has a discontinuous spiral shape. Are located in Therefore, the high-viscosity liquid supplied from the inlet advances while being continuously stirred and kneaded toward the outlet in the direction of arrow a '.

とはいうまでもない。In this embodiment, one fan-shaped blade 5 is set to four and the other fan-shaped blade 10 is set to two.
The fan blades need only have a combination of blades in a ratio of 2: 1. Needless to say, one fan blade may have six blades and the other blade may have three blades.

液を切り裂くように剪断し混練が更に助勢できる。According to the present invention, since the stirring blades rotate between the shafts at different speeds so as to bite each other, the high-viscosity liquid is pushed toward the inner surface of the casing between the two shafts. Is moved along both side walls of the fan blade, and the liquid is sent by the thickness of the plate on the slope of the fan blade with the disk cut out,
Since it is pulled in by the negative pressure generated on the opposite slope, it can be further stirred and kneaded with a simple configuration, and since the leading end of the fan-shaped blade has an acute angle, it can cut high viscosity liquid. And kneading can be further assisted.
更に、断面平行四辺形の羽根であるので、スクレーピ
ングが良好に行われ翼面に高粘度液が付着しにくい。Furthermore, since the blade has a parallelogram cross section, the scraping is performed well, and the high-viscosity liquid hardly adheres to the blade surface.
