When the space inside the tank body is sufficient, the pH monitoring probe can remain stationary, and the pH change of the fermentation broth can be monitored in real time.

[0028] Further, the tank body 1 is provided with a stirrer, which is arranged at the bottom of the tank body. The inner top of the tank body 1 is provided with an automatic spraying device, and the pH online monitoring device, the stirrer and the automatic spraying device are respectively connected with a controller. The stirrer can be arranged in multiple according to the size of the tank body, and is connected by a belt, so that only one stirrer needs to be driven to rotate to realize the rotation of all the stirrers at the same time for stirring operation. The stirrer mainly mixes and reacts the fermentation broth with the reagent in the feeding tank, and the automatic spraying device automatically sprays the reagent in the feeding tank into the tank body according to the monitored pH value.

[0029] Further, the stirrer includes a rotating shaft 9, which is arranged through the bottom of the tank body 1 and fixed by a bearing. The end of the rotating shaft 9 extending into the tank body 1 is provided with a blade 10 around the circumference, and the end of the rotating shaft 9 extending out of the tank body 1 is sleeved with a grooved wheel 11.
