In the present embodiment, when it is necessary to neutralize the acidity of the solution in the cleaning container 120, the driving module 210 can first drive the extraction tube 223 and the third injection tube 224 to move toward the cleaning container 120, so that the extraction tube 223 is suitable for extracting the solution in the cleaning container 120, and the third injection tube 224 is suitable for filling pure water into the cleaning container 120; then, after extracting the solution in the cleaning container 120 through the extraction tube 223, pure water is added into the cleaning container 120 through the third injection tube 224 to dilute the solution in the cleaning container 120; finally, alkaline substances are added into the cleaning container 120 through the acid-base regulating device, that is, alkaline solution is added into the cleaning container 120 through the second injection tube 222, and the solution in the cleaning container 120 is stirred by the agitator 230, thereby effectively reducing the filling amount of the alkaline solution, effectively preventing the solution from overflowing from the cleaning container 120, and saving resources.

[0089] In this embodiment, refer to Figure 2 , Figure 3 and Figure 5As shown, the liquid adding and stirring mechanism 200 also includes a pH detector 240 disposed on the driving module 210. The pH detector 240 is used to detect the pH value of the solution in the cleaning container 120, so as to accurately control the pH value of the solution in the cleaning container 120 to ensure a better cleaning effect on the graphene powder. In this embodiment, the pH detector 240 can be driven by the driving module 210 to extend into the solution in the cleaning container 120 to detect the pH value of the solution in the cleaning container 120, which is convenient for operation.

The TDS detector 250 is used to detect the TDS value of the solution in the cleaning container 120 to accurately control the total amount of soluble solids in the cleaning container 120 to ensure a better cleaning effect on the graphene powder. In this embodiment, when the pH value in the cleaning container 120 after filling with alkaline solution and stirring meets the requirements, the solution in the cleaning container 120 is extracted through the extraction pipe 223 in sequence, pure water is added to the cleaning container 120 through the third injection pipe 224, and the solution in the cleaning container 120 is stirred by the agitator 230, and then the TDS value of the solution in the cleaning container 120 is detected by the TDS detector 250. When the TDS value meets the requirements, the cleaning of the graphene powder is completed; when the TDS value does not meet the requirements, the extraction of the solution in the cleaning container 120, the filling of pure water into the cleaning container 120, and the stirring of the solution in the cleaning container 120 can be repeated in sequence until the TDS value meets the requirements, and the cleaning of the graphene powder is completed.

In this embodiment, the position of the liquid adding and stirring mechanism 200 in the horizontal direction can be adjusted by the transplanting mechanism 300 to adjust the relative position of the first liquid injection pipe 221, the second liquid injection pipe 222, the third liquid injection pipe 224, the liquid extraction pipe 223, the stirrer 230, the pH detector 240 and the TDS detector 250 with the cleaning container 120 in the horizontal direction, effectively preventing the solution from splashing out of the cleaning container 120 during filling, and making the stirrer 230 more suitable for stirring the solution.

[0099] In a feasible implementation manner, when the first injection pipe 221 fills the acidic solution into the cleaning container 120, or the third injection pipe 224 fills the pure water into the cleaning container 120, or the extraction pipe 223 extracts the solution in the cleaning container 120, the second injection pipe 222 and the agitator 230 are projected in the vertical direction outside the cleaning container 120 to prevent the second injection pipe 222 and the agitator 230 from dripping into the cleaning container 120; when the second injection pipe 222 fills the alkaline solution into the cleaning container 120, or the agitator 230 stirs the solution in the cleaning container 120, the first injection pipe 221, the third injection pipe 224 and the extraction pipe 223 are projected in the vertical direction outside the cleaning container 120 to prevent the first injection pipe 221, the third injection pipe 224 and the extraction pipe 223 from dripping into the cleaning container 120.

[0114] In this embodiment, continue to refer to Figure 6 and Figure 7 As shown, a second container 620 is also provided on the support frame 100, and the second container 620 is used to store an alkaline solution. The second injection pipe 222 is connected to the second container 620, that is, the second injection pipe 222 draws the alkaline solution in the second container 620 and injects it into the cleaning container 120, which is convenient for operation.

[0128] Among them, between step S120 and step S130, the pH value in the cleaning container 120 can be detected by the pH detector 240. Exemplarily, if 1≤PH≤2, the cleaning container 120 can be left standing for a time T.
