Description

Technical Field

[0001] The utility model relates to the technical field, and in particular to an online pH meter which is convenient for flushing electrodes. Background Art

[0002] Online pH detector is a highly intelligent online continuous monitoring instrument, which consists of two parts: sensor and secondary meter. It can be equipped with three-composite or two-composite electrodes to meet various use occasions. It can be equipped with pure water and ultrapure water electrodes and is suitable for pH value measurement of water with conductivity less than 3μs / cm (such as chemical feed water, saturated steam, condensed water, etc.).

[0003] A Chinese patent discloses an online PH detector for detecting PH values, with the publication number CN216132979U. The article proposes "an online PH detector for detecting PH values, the technical scheme of which is: comprising a test table, a detection probe and a heat insulation and anti-corrosion component, the rear end of the test table is connected to the detection probe through a detection line, the detection probe comprises a probe housing and a temperature sensor and a PH value sensor installed inside the probe housing, the inner wall of the probe housing is installed with a heat insulation and anti-corrosion component, the heat insulation and anti-corrosion component comprises a heat insulation pad, heat dissipation silicone grease, a protective cover and an anti-corrosion probe, the outer wall of the heat insulation pad is evenly distributed with a support cushion layer, and the beneficial effect is: the utility model can detect the temperature sensor and the PH value sensor by setting a probe housing, a plug and a protective cover made of ceramic material. The sensor is protected against corrosion, and the heat outside the probe shell is isolated by setting a heat insulation pad and a support block for use, thereby increasing the service life of the detection probe. When the above utility model is in use, the probability of damage to the electrode due to excessive heat is reduced by protecting the heat insulation pad inside the probe shell and the support block electrode, while extending the service life of the electrode. However, the electrode of the device is fixedly installed inside the probe shell and is not easy to be removed, resulting in the electrode being difficult to be removed and rinsed when it needs to be cleaned after being used for many times. At the same time, the probe is connected to the test table, so that the flushing water of the device spreads to the test table during flushing, causing damage to the test table. Therefore, it is necessary to design an online pH meter that is easy to flush the electrode. Utility Model Content

[0004] The utility model aims to provide an online pH meter which is convenient for flushing electrodes, and solves the problem in the related art that the electrodes of the device are fixedly installed inside the probe shell and are not easy to be taken out, resulting in that when the electrodes need to be cleaned after being used for many times, the electrodes may not be easy to be taken out and flushed, and at the same time, the probe is connected with a test table, so that when the device is flushed, the flushing water affects the test table, causing damage to the test table.

[0016] 1. In this way, the limit seat is driven by the electric telescopic rod to move to the maximum height, so that it can be placed in a higher position, thereby reducing the possibility of the detector being contaminated by the flushing liquid. At the same time, the cable is fixed and limited by the first limit plate to prevent the positive and negative electrodes from moving during cleaning, causing water to enter the cable and further damaging the cable. At the same time, the second limit ring limits and fixes the detection seat, so that the positive and negative electrodes can keep the positive and negative electrode ends in a vertical downward state during cleaning, so that the positive and negative electrodes can be better cleaned, and the positive and negative electrode ends are downward, so that the cleaning water can flow downward under the influence of gravity, which is convenient for the positive and negative electrodes to drain water and avoid the backflow of sewage, thereby improving the cleanliness of the positive and negative electrodes. At the same time, the first limit plate and the second limit plate act as baffles when cleaning the positive and negative electrodes to prevent the cleaning liquid from splashing when the positive and negative electrodes are cleaned, thereby ensuring that other detection instruments are in a relatively dry state, avoiding instrument damage and increasing the service life of the instrument.
