[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] In the embodiments of the present application, please refer to Figure 1 :

[0026] A self-cleaning pH on-line detector includes a pH meter 9, a vertical slide 2, a solenoid valve 3, a nozzle support 4, a gas-liquid nozzle 5, a horizontal slide 6, a buffer cup 7, a buffer support 8, a control cabinet, an aluminum profile frame 1 and an outer shell 10. The aluminum profile frame 1 is integrally L-shaped, and the outer shell 10 covers the outside of the aluminum profile frame 1. The vertical slide 2 is perpendicular to the horizontal slide 6, and the horizontal slide 6 is located below the vertical slide 2. The vertical slide 2, the horizontal slide 6 and the nozzle support 4 are all fixedly connected to the aluminum profile frame 1;

[0027] The pH meter 9 is installed on the output end of the vertical slide 2. The vertical slide 2 can drive the pH meter 9 to move up and down. The buffer bracket 8 is installed on the output end of the horizontal slide 6. The buffer cup 7 is placed on the buffer bracket 8. The horizontal slide 6 can drive the buffer bracket 8 and the buffer cup 7 to move horizontally.

[0028] At the nozzle support 4, there is a gas-liquid nozzle 5 aligned with the pH meter 9. One end of the solenoid valve 3 is connected to the gas-liquid nozzle 5 through a pipeline, and the other end is externally connected to a cleaning liquid storage tank through a pipeline. The cleaning liquid is set according to existing requirements with existing cleaning liquids. Buffer liquid is placed in the buffer cup 7, and the buffer liquid is used to neutralize the cleaning liquid.

[0029] When this application is in use, a support frame is also fixed at the bottom of the aluminum profile frame 1. The support frame can be an existing one, so that the object to be measured is located below the aluminum profile frame 1. During detection, the vertical slide 2 moves the pH meter 9 into the object to be measured below the aluminum profile frame 1 for detection.

[0030] When in use, the operation process of the self-cleaning pH on-line detector is as follows:

[0031] S1: The vertical slide 2 moves the pH meter 9 into the object to be measured below the aluminum profile frame 1 for detection;

[0032] S2: After the pH meter finishes detection, the vertical slide 2 raises the pH meter 9 to a preset position, then the solenoid valve 3 is activated, and the cleaning liquid is sprayed out through the gas-liquid nozzle 5 to flush the pH meter 9;

[0033] S3: After flushing, the vertical slide 2 raises the pH meter 9 to a position higher than the buffer cup 7, then moves the buffer cup 7 to a preset position through the horizontal slide 6, and the vertical slide 2 lowers the pH meter 9 into the buffer cup 7 and soaks it for a preset time;

[0034] S4: Then first raise the pH meter 9, move the buffer cup 7 back, and finally lower the pH meter 9 back to the original position for the next detection;

[0035] S5: Repeat the process of S1 - S4 to achieve continuous operation of the pH on-line detection 9.

[0036] The reagent liquids used above are all existing common liquids for cleaning the pH meter 9, which are determined according to the actual situation. The solenoid valve 3, the vertical slide 2, and the horizontal slide 6 can all be existing ones and are connected and controlled in an existing manner.
