The invention relates to the technical field of automatic control, in particular to a device and a method for automatically adjusting the rotating speed of a stirrer of a chemical clarification tank. Comprising a clarification tank; the water injection unit is used for injecting water into the clarification tank; the stirrer is used for stirring the mixed slurry in the clarification tank; the driving unit is used for driving the stirrer; the detection unit is used for detecting stirring parameters of the mixed slurry in real time; the controller is used for controlling the rotating speed of the stirrer according to the stirring parameters; wherein the stirring parameters comprise the liquid level height H of the clarification tank, the sludge concentration R in the clarification tank and the movement resistance F of the mixed slurry. The stirrer is dynamically adjusted in real time according to parameters such as sludge concentration and movement resistance of the slurry in the stirring process, so that the o
