[0061] Ion monitoring plays an important role in various fields such as environmental detection and industrial production. Corrosive ions can cause corrosion to many industrial equipment, so it is necessary to monitor ions to understand and master the influence of each ion. In ion monitoring, the ion concentration is generally measured by manual sampling titration measurement, which not only has a long operation period, high labor cost, but also has hysteresis, resulting in large measurement error.

[0062] As shown in Figure 1 , Figure 2 To solve the above technical problems, at least one embodiment of the application provides a measuring device for an ion monitoring system, which comprises:

[0069] As can be seen from the above, the sampling channel 220 is arranged on the outer shell 20 to provide a structural basis for the medium to be measured to enter and discharge the sampling groove 310. The sampling groove 310 is used to provide a structural basis for containing the medium to be measured. The detection electrode 50 is arranged to automatically measure the target ion concentration in the medium to be measured. Compared with the existing manual sampling titration measurement method, the measurement device of the present application not only has high automation degree, shortens the operation period, reduces the labor cost, but also improves the measurement accuracy, avoids the data lag caused by slow measurement, ensures that the concentration of the target ion in the medium to be measured can be obtained in real time, adjusts the production process in time, reduces the operation cost, and further provides strong technical support for safe and stable production.

[0133] It should be noted that the sampling section 2201 of the sampling channel 220 is connected with a sampling pipeline, and a sampling valve is arranged on the sampling pipeline, which is used to control the opening and closing of the sampling pipeline. Therefore, after the sampling groove 310 is connected with the sampling channel 220, the sampling valve needs to be opened, and the to-be-tested medium can enter the sampling groove 310. In addition, a preset measurement time interval can be set, and the sampling valve is opened after the preset measurement time interval, and the to-be-tested medium is injected into the sampling groove 310 through the sampling section 2201 of the sampling channel 220.

[0134] S103: measuring the to-be-tested medium in the sampling groove 310 through the detection electrode 50 to obtain the concentration of the target ion in the to-be-tested medium.

[0135] It should be noted that the specific type of the detection electrode 50 is determined according to the target ion to be measured, and the types of the plurality of detection electrodes 50 can be the same or different, which is not limited in the present application. For example, when the target ion is a chloride ion, the detection electrode 50 is a chloride ion selective detection electrode 50.

[0136] In some embodiments, the measuring the to-be-tested medium in the sampling groove 310 through the detection electrode 50 to obtain the concentration of the target ion in the to-be-tested medium further includes:

[0137] After a preset detection time interval, the to-be-tested medium after measurement is discharged through the sampling section 2204 of the sampling channel 220;

[0138] The target ion concentration is sent to the control end.

[0139] It should be noted that the preset detection time interval is set according to actual needs, for example, the preset detection time interval is 20s.

[0140] It should be further noted that the sampling section 2204 of the sampling channel 220 is connected with a sampling pipeline, and a sampling valve is arranged on the sampling pipeline, which is used to control the opening and closing of the sampling pipeline.

[0141] In some embodiments, it further includes:

[0142] The sampling groove 310 on the inner housing 30 is connected with the flushing channel 230 on the outer housing 20 by rotating the inner housing 30 through the driving member 40;

[0146] The outer shell 20 is provided with a plurality of flushing channels 230, which are arranged at equal intervals around the outer shell 20. The plurality of flushing channels 230 and the plurality of sampling channels 220 are arranged at equal intervals around the outer shell 20. The number of flushing channels 230, sampling channels 220, sampling slots 310 and detection electrodes 50 is equal; for example, Figure 2 As shown, there are two flushing channels 230, and the angle between the two flushing channels 230 is 180°. There are two sampling slots 310, and the angle between two adjacent sampling slots 310 is 180°. Detection electrodes 50 are provided in the two sampling slots 310. The angle between the flushing channel 230 and the corresponding sampling slot 310 is 90°, so the driving member drives the inner shell 30 to rotate 90°, thereby ensuring that the sampling slots 310 are respectively connected to the corresponding flushing channels 230.

[0147] It should also be noted that the liquid inlet section 2301 of the flushing channel 230 is connected to the liquid inlet pipeline, and a liquid inlet valve is provided on the liquid inlet pipeline. The liquid inlet valve is used to control the on-off of the liquid inlet pipeline. Therefore, after the sampling tank 310 is connected to the flushing channel 230, the liquid inlet valve needs to be opened so that the flushing liquid can enter the sampling tank 310.

[0148] It should also be noted that the preset cleaning time interval is set according to actual needs. For example, the preset cleaning time interval is 30s.

[0149] It should also be noted that the liquid outlet section 2304 of the flushing channel 230 is connected to the liquid outlet pipeline, and a liquid outlet valve is provided on the liquid outlet pipeline.
