Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the water quality analysis pretreatment device of the on-line control potential of hydrogen that a kind of structure is simple, working efficiency is high, sharpness of regulation is good.
For achieving the above object, the technical scheme that the utility model proposes is: a kind of water quality analysis pretreatment device of on-line control potential of hydrogen, comprise sampling cup, it is characterized in that: also comprise former water pot, mark flow container, acid solution tank, alkali liquid tank, first pump housing, second pump housing, the 3rd pump housing, pH analytical equipment and PLC, described former water pot is connected first pump housing, sampling cup with mark flow container successively by pipeline, acid solution tank connects second pump housing, sampling cup successively by pipeline, and alkali liquid tank connects the 3rd pump housing, sampling cup successively by pipeline; Described pH analytical equipment comprises pH on line analyzer and pH probe, and described pH probe is located at sampling cup inside, and connect pH on line analyzer, described PLC connects first pump housing, second pump housing, the 3rd pump housing, pH on line analyzer.
Further, also comprise a drain pump be connected with sampling cup by pipeline, described drain pump connects PLC.
Further, also comprise an air pump be connected with sampling cup by pipeline, described air pump connects PLC, for stirring the liquid in sampling cup.
Adopt technique scheme, the water quality analysis pretreatment device of on-line control potential of hydrogen described in the utility model, can be implemented in line automation potential of hydrogen and regulate, there is the advantages such as structure is simple, working efficiency is high, sharpness of regulation is good.
Accompanying drawing explanation
Fig. 1 is the water quality analysis pretreatment device structural representation of on-line control potential of hydrogen described in the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the water quality analysis pretreatment device of on-line control potential of hydrogen described in the utility model, comprise sampling cup 10, former water pot 11, mark flow container 12, acid solution tank 13, alkali liquid tank 14, first pump housing 15, second pump housing 16, 3rd pump housing 17, pH analytical equipment 18 and PLC (not shown), drain pump 20, air pump 19, described former water pot 11 is connected first pump housing 15 with mark flow container 12 successively by pipeline, sampling cup 10, acid solution tank 13 connects second pump housing 16 successively by pipeline, sampling cup 10, alkali liquid tank 14 connects the 3rd pump housing 17 successively by pipeline, sampling cup 10, described drain pump 20, air pump 19 connect sampling cup 10 by pipeline, described pH analytical equipment 18 comprises pH on line analyzer 180 and pH probe 181, it is inner that described pH probe 181 is located at sampling cup 10, connect pH on line analyzer 180, described PLC connects first pump housing 15, second pump housing 16, the 3rd pump housing 17, pH on line analyzer 180, drain pump 20, air pump 19.
During concrete use, first pass through the first pump housing draw samples or mark liquid in sampling cup, open drain pump simultaneously, exhaust-valve is closed after air is emptied completely, first pump housing continues to sample in sampling cup, pH meter detection sample P H value after certain water level to be achieved, controls second pump housing or the 3rd pump housing carries out stopping dosing after dosing adjustment potential of hydrogen reaches the requirement of analyser, has the advantages such as structure is simple, working efficiency is high, sharpness of regulation is good.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
