Abstract
The utility model discloses a double-electrode self-cleaning pH online measurement device which comprises a fixed bracket. The middle part of the fixed bracket is provided with an internal fixed plate; the internal fixed plate is provided with an ultrasonic cleaning device and two pH testing electrodes; the ultrasonic cleaning device is close to the positions of probes of the pH testing electrodes. The double-electrode self-cleaning pH online measurement device is suitable for testing the pH of a complex ion system and a high viscosity liquid system, implements self-cleaning and carries out continuous testing on a solution system; as two parallel pH testing electrodes are arranged on the internal fixed plate to form a double-electrode system, the pH of the systems can be respectively and independently measured; accuracy of a measurement result is ensured; after one testing electrode has a fault, the testing electrode with the fault can be independently taken out to be cleaned and calibrated and continuity of monitoring is ensured; meanwhile, the ultrasonic cleaning device is adopted, labor is saved, work efficiency is improved, the problem of adhesion of solution to the electrodes is solved, and accuracy of measurement is ensured.
Description
Technical field
The utility model relates to a kind of pH on-line measurement device, is specifically related to a kind of bipolar electrode self-cleaning pH on-line measurement device.
Background technology
Aspect commercial production and environmental monitoring, need to measure and on-line monitoring the pH of operation architecture, due to the complicacy of complex and the on-line continuous testing requirement of automated production in producing, to the measurement of pH, require more and more higher, the high viscosity corrosive liquids system of complicated ions system in chemical industry particularly, both require the pH value of measurement accurate, stablized, and required again measurement mechanism to realize good continuity.In complicated ions system, because effects of ion is more, easily contaminant sensor probe is very easily polluted it under the state of continuous detecting, and accuracy of detection declines; For high viscosity corrosive liquids system, because solution viscosity is large, easily stick on probe, pH is measured cannot carry out, to carry out frequent clean to pH potential electrode, in production, often by manually electrode being taken out to Manual-cleaning probe when rinsing, have during this period of time the problem of individual pH value distortion, this has just caused the uncontinuity of monitoring.
Utility model content
The purpose of this utility model is for a kind of bipolar electrode self-cleaning pH on-line measurement device is provided, and when solving existing manual cleaning pH potential electrode, the pH value out of true of measurement, unstable, accuracy of detection is low, can not realize good successional technical matters.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of bipolar electrode self-cleaning pH on-line measurement device, comprise fixed support, described support bracket fastened middle part is provided with inner fixed head, described inner fixed head is provided with ultrasonic cleaning equipment and 2 pH test electrodes, and described ultrasonic cleaning equipment is near pH test electrode probe place.
As further improvement of the utility model, described ultrasonic cleaning equipment is provided with ultrasonic cleaning equipment seal box.
As further improvement of the utility model, described support bracket fastened top is provided with handle.
The relative prior art of the utility model has following beneficial effect: the utility model is applicable to the mensuration of complicated ions system and high viscosity liquid system pH, realized self-cleaning and solution system has been carried out to successional mensuration, by being set on inner fixed head, 2 parallel pH test electrodes form bipolar electrode system, can to the pH of system, measure separately respectively, guaranteed the accuracy of measurement result, after a test electrode goes wrong, can take out separately and clean demarcation, and guarantee the continuity of monitoring; Adopt ultrasonic cleaning equipment simultaneously, saved manpower, improved work efficiency, and solved the sticking problem of solution to electrode, guaranteed the accuracy of measuring.
