Example 3
The embodiment provides a method for verifying an electrode protection device for a fermentation environment, which comprises the following steps,
s1, before the electrode is checked, a controller 500 controls a water pump 220 to work, so that a solution in a container 210 flows into a protection assembly 100, and when a liquid level sensor 300 detects that the liquid level in the protection assembly 100 reaches a set height, the controller 500 controls the water pump 220 to stop working;
s2, the electrode starts detection operation, the deviation of the solution detection value of the electrode in the protection assembly 100 and the theoretical detection value of the standard solution is within a set range, the verification is passed, and if the deviation exceeds the set range, the verification is not passed.
The electrode can be used for detecting the pH value or the dissolved oxygen amount of the solution in the container 210 in the fermentation environment, and if the deviation between the detection value of the electrode and the theoretical detection value of the solution exceeds a set range, the verification of the electrode does not pass, and the fermentation is stopped; if the deviation between the detection value of the electrode and the theoretical detection value of the solution is within a set range, the electrode is verified to pass, and the fermentation can be performed. In this embodiment, the electrodes may be pH electrodes or dissolved oxygen electrodes, and different types of electrodes are used to detect different physical parameters.
For example, if the electrode type is a pH electrode, the electrode detects the pH value of the solution, and if the pH value of the solution detected by the electrode is 8.2 and the theoretical pH value of the solution is 9.5, the deviation between the two values is 1.3, and exceeds the set range of 0.2 to 0.4, the electrode fails to be verified, and the electrode must be replaced or repaired. Otherwise, if the deviation value is within the set range, the verification of the electrode is passed.
In the above embodiments of the present invention, the differences between the embodiments are described in emphasis, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.
The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are merely exemplary embodiments of the present invention, and are not intended to limit the scope of the present invention, and any modifications, equivalent substitutions, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
