Description
Technical field
The utility model belongs to species analysis Instrument technology field, specifically just relates to a kind of pH combination electrode of disassembling cleaning, can disassemble and clean.
Background technology
Combination electrode has been widely used in the measurement of pH value, is exactly pH combination electrode the electrode that pH glass electrode and contrast electrode are combined.At present in test process according to the feature of test sample, adopt different reference structures and sensing glass ball bubble, further pH combination electrode be divided into the electrode special being applicable to different application environment.
PH electrode test technology is very ripe, but in actual applications, has a lot of testing sample to contain a large amount of suspension or thickness own, easily stick to the measuring junction of pH electrode, the performance of pH electrode is declined rapidly.Particularly easily make electrode Reference system liquid meet boundary blocked, be difficult to be recovered by general cleaning method.
Ye Jie circle of common pH electrode is generally porous structure or narrow slit structure, stains blocking and is just difficult to thoroughly be cleaned, thus cause the life-span of pH electrode greatly to shorten once contaminated thing.
Easily block the defect of not easy cleaning to improve existing PH combination electrode Ye Jie circle, occurring on the market can disengaged glass or glass plastic ground Ye Jie circle, for measuring the strong sample of contaminative.Once the contaminated hydraulic performance decline of electrode, ground can be thrown off and clean.But because existing ground can only do disengaging among a small circle, once pollutant enter even be attached to electrode shell inside ground inwall or Inner electrode on, thorough cleaning will be difficult to, long term accumulation will affect electrode performance, reduce and measure, if thoroughly dismantled by electrode shell, outer reference system is then easily damaged or dry is difficult to restorability, can shorten electrode life equally.
Utility model content
The purpose of this utility model is exactly the technological deficiency being difficult to cleaning for existing PH combination electrode, a kind of pH combination electrode of disassembling cleaning is provided, according to electrode fouling degree, electrode can be cleaned, extend the serviceable life of electrode, improve measuring accuracy.
Technical scheme
In order to realize above-mentioned technical purpose, the utility model designs a kind of pH combination electrode of disassembling cleaning, it comprises electrode shell and interior electrode, interior electrode is contained in electrode shell, electrode shell and Inner electrode contact part adopt plastics ground as Ye Jie circle, it is characterized in that: described interior electrode is threaded with electrode cap, spring is provided with in the electrode cap inner chamber on electrode shell top, spring props up electrode shell, interior electrode tail end is taper, and electrode shell props up interior electrode taper end under the action of the spring.
Further, described spring housing is contained in interior electrode upper end.
Further, described interior electrode is provided with reference junction, and reference junction is suppressed by the potpourri of one or several in silver chloride, silver bromide, silver iodide, silver sulfide, copper sulfide, silver powder and formed.
Further, outer reference solution is full of in described electrode shell.
Beneficial effect
The utility model provides a kind of pH combination electrode of disassembling cleaning, can be cleaned by electrode, extend the serviceable life of electrode, improve measuring accuracy according to electrode fouling degree.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is that the utility model unclamps electrode cap structural representation.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
Embodiment
As shown in figure 1 and 2, a kind of pH combination electrode of disassembling cleaning, it comprises electrode shell 1 and interior electrode 2, interior electrode 2 is contained in electrode shell 1, and electrode shell 1 and Inner electrode 2 contact portion adopt plastics ground as Ye Jie circle, it is characterized in that: described interior electrode 2 is threaded with electrode cap 3, spring 4 is provided with in electrode cap 3 inner chamber on electrode shell 1 top, spring 4 props up electrode shell 1, and interior electrode 2 tail end is taper, and electrode shell 1 props up interior electrode 2 taper end under spring 4 acts on.
Described spring 4 is sleeved on interior electrode 2 upper end.
Described interior electrode 2 is provided with reference junction 201, and reference junction 201 is suppressed by the potpourri of one or several in silver chloride, silver bromide, silver iodide, silver sulfide, copper sulfide, silver powder and formed.
Outer reference solution 5 is full of in described electrode shell 1.
In the utility model when Inner electrode 2 and electrode cap 3 screw mutually, by extrusion spring 4, electrode shell 1 and Inner electrode 2 are compressed, thus electrode is normally worked.Electrode shell 1 and Inner electrode, reference junction 201 replaces the common filamentary silver being coated with silver chloride to produce constant reference potential.Reference junction 201 hard wear resistant, can not by common solvent corrosion.Contaminated rear available soft brush and washing agent cleaning.Reference system do not exist dry after be difficult to the shortcoming recovered, electrode for a long time dry put after, again add outer reference solution and can use immediately.
When electrode is by slight pollution, electrode cap 3 can be pressed, again add after releasing outer reference solution, can normal operating conditions be recovered.If electrode interior is contaminated thing attachment also, electrode cap 3 of outwarding winding, once takes off electrode cap 3 from Inner electrode 2, spring 2, electrode shell 1, reinstalls and adds outer reference solution and can reuse respectively with after soft brush and washing agent cleaning.
