Description
Technical field
The utility model relates to a kind of electrochemical measuring technique field, particularly relates to a kind of pH pick-up unit.
Background technology
The measurement of desulfurizer gypsum slurries pH value, be on gypsum extraction pump outlet conduit, arm to be installed mostly, and on arm, plug-in electrode be installed at present, introduces simultaneously wash-down water, rinses the pH electrode.But in actual use, the pH electrode that is contained on pipeline is in the slurry flow rate higher position, the easy erosive wear electrode of slurries, and rinse the mouth of a river over against electrode, and also can cause and must impact electrode, when serious, glass electrode is damaged, can't use.When detecting, keeping in repair or dismantling plug-in electrode, due to gypsum particle caking around electrode, cause dismounting difficult.When system need to stop transport a period of time; the operation maintenance personnel need the pH electrode is removed in invasion water to protect; otherwise being exposed in air for a long time, electrode can affect measuring accuracy; when serious, electrode failure is scrapped; and being many operation maintenance personnel, this point thinks little of or strict implement not; usually cause the wet protection of pH electrode not to be in time, cause the pH electrode not use for a long time.
The utility model content
The utility model is to solve that gypsum slurries pH value detection device commonly used is fragile, the problem of easy care not, provides a kind of DATA REASONING accurate stable, the pH pick-up unit of long service life and easy care.
In order to address the above problem, the utility model is achieved through the following technical solutions:
PH pick-up unit of the present utility model, comprise that one is provided with main body, pH electrode, input pipe, efferent duct, water inlet pipe and the blow-off pipe of cavity, described pH electrode is comprised of electrode body and electrode contact, described main body top is provided with the pH electrode, the electrode contact of described pH electrode stretches in the cavity of main body, input pipe and blow-off pipe are connected with cavity bottom respectively, and efferent duct and water inlet pipe are connected with the top of cavity respectively.
Further, described input pipe, water inlet pipe and blow-off pipe are provided with valve.
Compared with prior art, the beneficial effects of the utility model are: pH pick-up unit DATA REASONING of the present utility model is accurate, stable, reliable, long service life, and the installation site is flexible, easy care.
Description of drawings
Fig. 1 is the structural representation of pH pick-up unit of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
PH pick-up unit of the present utility model as shown in Figure 1, comprise that one is provided with main body 1, pH electrode 2, input pipe 3, efferent duct 4, water inlet pipe 5 and the blow-off pipe 6 of cavity, pH electrode 2 is comprised of electrode body and electrode contact 7, main body 1 top is provided with pH electrode 2, the electrode contact 7 of pH electrode 2 stretches in the cavity of main body 1, input pipe 3 and blow-off pipe 6 are connected with cavity bottom respectively, and efferent duct 4 and water inlet pipe 5 are connected with the top of cavity respectively.Like this, slurries enter by input pipe in the cavity of main body, and in main body, the velocity ratio of slurries is slower like this, and is little to the erosion of pH electrode, have ensured the accurate, stable, reliable of DATA REASONING, and slurries flow to the desulphurization system melt pit by efferent duct; When the pH pick-up unit was safeguarded, the operation maintenance personnel can inject wash-down water to cavity by water inlet pipe electrode is regularly rinsed, and wash-down water flows out by blow-off pipe, and maintenance work is simple; The maintainer also can carry out water conservation to the pH electrode by water inlet pipe to filling with water in cavity, has extended the serviceable life of pH electrode.
The input pipe 3 of pH pick-up unit of the present utility model, water inlet pipe 5 and blow-off pipe 6 are provided with valve; Like this, the controlled slurrying flow velocity of the valve on input pipe further reduces slurries to the erosion of pH electrode, and the valve on water inlet pipe 5 and blow-off pipe 6 is easy-to-use, has strengthened practicality of the present utility model.
The extraction pump of PH pick-up unit of the present utility model and desulfurizer is used in conjunction with, and usually be arranged on outlet conduit, and its input pipe is connected with the outlet conduit of extraction pump, and the installation site flexibly and be easy to remove.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
