一般に高粘性物質の混線1反応等の連続処理においては

りしてスケーリング等の原因となる。In general, in continuous processing such as crosstalk single reaction of highly viscous substances, it is required to minimize the dead space within the apparatus and to perform an operation similar to extrusion flow. For this reason, various designs have been devised in which a horizontally long cylindrical container is used and two stirring blades are installed in the longitudinal direction. For example,
As shown in No. 29019, there is a structure in which the paddle ends are arranged in multiple stages to scrape the entire inner surface of the container to reduce the dead space, but the liquid to be treated has a high viscosity of several thousand poise or more. In this case, there is a problem in that the liquid adhering to the surface of the rotating shaft rotates together, causing scaling and the like. Therefore, an attempt was made to eliminate this rotating shaft and reduce the co-rotation, and as proposed in Japanese Patent Publication No. 49-40732, the outer periphery of a partially hollowed out disk was connected to eliminate the rotating shaft. There is something I did. This eliminates co-rotation around the rotating shaft, but the highly viscous liquid adhering to the surface of the disc-shaped stirring blade is difficult to flow and co-rotates around the blade, causing scaling.
そして、現状の装置の攪拌は、一方向に一定速度で行な
っているため、翼表面等に付着した液は共まわりを起し
やすい。Furthermore, since the current device stirs at a constant speed in one direction, the liquid adhering to the surfaces of the blades etc. tends to rotate together.
上記従来技術は、被処理液が数千ポアズ以上の高粘度に
なると、問題になる共まわりの点について配慮がされて
おらず、スケーリング等の原因となる点1こ問題があっ
た。The above-mentioned prior art does not take into account the issue of co-circulation, which becomes a problem when the liquid to be treated has a high viscosity of several thousand poise or more, and has one problem, which may cause scaling, etc.
本発明の目的は、容器内のデッドスペースを少なくする
と共に、液の共回りを防止した高粘性物質の連続処理方
法を提供することにある。An object of the present invention is to provide a continuous processing method for highly viscous substances that reduces dead space within a container and prevents liquid from co-circulating.
上記目的は、水平に設置された円筒状容器内の長手方向
両端部に2本の回転耳軸を並設し、前記長手方向の回転

続撹袢処理すると共に、前記攪拌翼を周期的に一時停止
させて連続撹袢処理することにより、達成される。The above purpose is to install two rotary ear shafts in parallel at both ends in the longitudinal direction in a cylindrical container installed horizontally, and to connect a plurality of rod-like rectangular frame stirring blades between the rotary ear shafts in the longitudinal direction. The high viscosity substance is removed by the stirring blade by holding the rotary ear shafts arranged in parallel so that the tip of the rod-like foot-shaped frame of one of the corresponding stirring blades passes close to the center of rotation of the other stirring blade. This is achieved by carrying out a continuous stirring process and periodically stopping the stirring blade to perform a continuous stirring process.

回りするのを防止することができる。By passing a pair of stirring blades made up of several rod-shaped rectangular frames connected so that the tip of the rod-shaped rectangular frame of one of the corresponding stirring blades is close to the center of rotation of the other stirring blade, the dead inside the container can be removed. In addition, by temporarily stopping the rotational movement of the stirring blade, the liquid to be treated that has adhered to the stirring blade will fall under its own weight, and this can be periodically stirred. It is possible to prevent the liquid to be treated from adhering to the blades and rotating together.
