Description
Technical field
A kind of electrode protecting device is the utility model is related to, more particularly to a kind of protection device of platinum plate electrode.
Background technology
Potentiometric titrimeter is the common a kind of analytical instrument for content analysis designed according to potentiometry principle.Principle
A working battery as is formed from appropriate indicator electrode and reference electrode and detected solution, with the addition of titrant,
Due to chemically reacting, constantly changed by the concentration of measured ion, thus the current potential of indicator electrode changes therewith.Titrating
Near terminal, tested ion concentration is undergone mutation, and causes the hop of electrode potential, therefore can determine titration eventually according to this phenomenon
Point.
The potentiometric titrimeter typically used need to connect leaf electrode and platinum plate electrode.Platinum plate electrode is measurement redox electricity
The indicator electrode of position, with tungsten electrode or calomel electrode（Reference electrode）Used after supporting.In actual titration operation, it is necessary to plus
Entering stirrer ensures that reaction is complete, and when electrode is inserted solution, because liquor capacity is smaller, exposed platinized platinum can touch unavoidably
Beaker bottom, or the stirrer that is being stirred hit, and this easily causes the damage of pole piece so as to shorten its service life.And
Platinum plate electrode plays conclusive effect in entirely analysis continuous mode, and the quality of platinum plate electrode directly affects the good of data
It is bad, when platinum plate electrode measures the failure that will do not cause to test on time or the quality for having a strong impact on product because of damage.Therefore, it is necessary to
A kind of equipment that can protect exposed platinized platinum.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided a kind of protection device of platinum plate electrode, keeps away
Exempt from platinum plate electrode and touch beaker or stirrer, extend the service life of platinum plate electrode, improve the accuracy of experiment.
In order to achieve the above object, the technical solution adopted in the utility model is：
A kind of protection device of platinum plate electrode, including platinum plate electrode, the exposed platinized platinum overcoat in described platinum plate electrode lower end
Equipped with sleeve pipe, described sleeve pipe extends downward into the bottom more than platinum plate electrode, is provided with the side wall of described sleeve pipe for molten
The logical circulation groove of liquid stream.
As preferred embodiment of the present utility model, at least two circulations are provided with sleeve pipe described in the utility model
Groove.
As preferred embodiment of the present utility model, circulation groove described in the utility model is arranged to even number, circulation groove
It is uniformly distributed around sleeve pipe periphery.
As preferred embodiment of the present utility model, the lower end of circulation groove described in the utility model is arranged to opening knot
Structure.
As preferred embodiment of the present utility model, sleeve pipe described in the utility model is plastic tube.
Compared with prior art, the beneficial effects of the utility model are：Sleeve pipe and set are set with outside exposed platinum plate electrode

The perfect contact of electrode, meet the requirement of measurement while convenient flushing electrode.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1. platinum plate electrode；101. platinized platinum；2. sleeve pipe；3. circulation groove.
Embodiment
Purport of the present utility model is overcome the deficiencies in the prior art, there is provided a kind of protection device of platinum plate electrode, keeps away
Exempt from platinum plate electrode and touch beaker or stirrer, extend the service life of platinum plate electrode, improve the accuracy of experiment.
It is described in detail referring to the drawings with reference to embodiment, to enter to the technical characteristics of the utility model and advantage
Row deeper into annotation.
The utility model is as shown in figure 1, disclose a kind of protection device of platinum plate electrode, including platinum plate electrode 1, described
Sleeve pipe 2 is set with outside the exposed platinized platinum 101 in the lower end of platinum plate electrode 1, described sleeve pipe 2 is extended downward into more than platinum plate electrode 1
Bottom, the circulation groove 3 for solution circulation is provided with the side wall of described sleeve pipe 2.General potentiometric titrimeter needs platinum plate electrode 1
As the indicator electrode of measurement oxidation-reduction potential, platinum plate electrode 1 is inserted into solution in practical operation, while stirrer pair
Solution is stirred, and sleeve pipe 2 avoids platinum plate electrode 1 from being touched with beaker bottom or stirrer, extends the use of platinum plate electrode 1
In the life-span, the accuracy of measurement result is improved, circulation groove 3 is set, be easy to solution to flow into sleeve pipe 2 and contacted with platinum plate electrode 1.
It is preferred that at least two circulation grooves 3 are provided with described sleeve pipe 2.More than two circulation grooves 3 are advantageous to solution
Flowing in sleeve pipe 2, and it is easy to platinum plate electrode 1 to be contacted with solution, the result of measurement is more accurate.
It is preferred that described circulation groove 3 is arranged to even number, circulation groove 3 is uniformly distributed around the periphery of sleeve pipe 2.Circulation
Groove 3 is even number, and relative two circulation grooves 3 are in 180 degree, and the level of being located along the same line communicates, and solution can pass through circulation groove 3
Contacted with the perfection of platinum plate electrode 1, meet the requirement of measurement while convenient flushing electrode.
It is preferred that the lower end of described circulation groove 3 is set on mouth structure.The lower end of circulation groove 3 directly contacts with solution, more
Added with the circulation in sleeve pipe 2 beneficial to solution.
It is preferred that described sleeve pipe 2 is plastic tube.The ductility of the protection sleeve pipe 2 is good, can high temperature resistant acid-fast alkali-proof,
