An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. 1 is the main body of the stirring tank; 2 is a bearing fixed to the inner end of the main body 1 with liquid circulation grooves 3 provided in the axial direction; 4 is a rotating shaft whose one end is supported by the bearing 2 via a sleeve 5; 6 is a screw provided at the end of the rotating shaft 4 adjacent to the bearing 2 in order to transfer the liquid in the main body 1 to the bearing 2 side, and 7 is a screw provided between the end of the bearing 2 opposite to the rotating shaft 4 and the main body. 1, a pressure sensor 8 is provided in the middle of the liquid circulation passage 7, and 9 is an outlet of the liquid circulation passage 7 on the main body 1 side.

槽に有効である。 In the above-described configuration, when the rotating shaft 4 rotates, the liquid in the main body 1 is transferred to the bearing 2 side by the screw 6, enters the liquid circulation groove 3, circulates through the bearing 2, and then circulates from the end of the bearing 2. It passes through the passage 7 and is returned into the main body 1 through the outlet 9. Further, by detecting the liquid pressure in the liquid circulation passage 7 with the pressure sensor 8, the lubrication performance in high viscosity liquid can be confirmed. Further, the viscosity of the liquid can be measured by calculating the detected liquid pressure, the distance from the mounting position of the pressure sensor 8 to the outlet 9 of the liquid circulation passage 7, and the discharge capacity of the screw 6. In particular, since there is a correlation between the viscosity and quality of polymeric substances (such as thermoplastic resins), it is effective in stirring tanks for substances with high viscosity of processing liquids, for example, polymeric substances such as polyethylene terephthalate.

In addition, since a shaft sealing device is not required, the device can be simplified. Furthermore, it is possible to eliminate the need for a separate liquid viscosity control.
