Description
Technical field
The present invention relates to a kind of instrument cleaning device, be specifically related to a kind of cleaning device that is used for cleaning automatically the sulphur meter electrolytic cell electrode.
Background technology
Using coulometric titration to survey electrolytic cell in the analytical instrument of sulphur in the coal is wherein core component, described electrolytic cell comprises 4 platinum electrodes, wherein 2 is indicator electrode, be used to detect the resistance sizes (concentration that directly reflects tested composition) of electrolytic solution, 2 is electrolysis electrode in addition, it produces in the material and tested composition after according to the state galvanization of indicator electrode, makes resistance get back to original state, thereby goes out tested composition by the detection indirect analysis to Faradaic current.Therefore the sensitivity (surface appearance) of 4 electrodes will directly influence the accuracy of test result, and all have electric current to pass through in the test process in the electrode, therefore its surface has various electrolysed substances generations, the meeting that has is attached to electrode surface fouling gradually, make the resistance increase make the sensitivity of electrode reduce the test duration prolongation, thereby make test result deviation occur.In order to guarantee precision of analysis, adopt artificial mode regularly the electrode of electrolytic cell to be cleaned at present, keep sensitivity so that remove the dirt of electrode surface.
At present, sulphur meter is plastics and organic glass (also useful glass) with electrolytic cell shape shell, want cleaning electrode its loam cake must be opened and take out electroded core body, take cotton ball soaked in alcohol that each electrode is carried out wiping with hand then, then electrode is carried out shaping and it is rinsed well with distilled water, ressemble by the dismounting inverted sequence at last, the time should guarantee the gas leakage when preventing to test that is in place of the O-ring seal of loam cake in assembling.Because of electrode material is noble metal (a platinum sheet), and electrode slice and lead-in wire (platinum wire of 0.5mm) be connected relatively more fragile, so must be careful during the wiping electrode, scrap in case break one then whole electrolytic cell; Use the electrolytic cell of long period in addition, electrode slice often curves, shaping causes a lot of surface irregularities of pit, so is difficult to guarantee that whole face all clips the position wiping time.Required to clean the once electrolytic pond in general one month, tenure of use is higher than the frequency of long cleaning, is very big burdens to operating personnel therefore.
Summary of the invention
Technical matters solved by the invention is to provide the electrolytic cell electrode automatic cleaning apparatus, and it is simple in structure, and is easy to operate, thereby solves the problem in the above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions:
The electrolytic cell electrode automatic cleaning apparatus, comprise control system and the stirring system that is connected with described control system, described control system is provided with four corresponding sockets of electrode with described electrolytic cell, described stirring system comprises the magnetic stirrer, and described magnetic stirrer is installed on described electrolytic cell bottom; The support that is used for the described electrolytic cell of support; Be used to drive the driver element of magnetic stirrer rotation.
As a kind of improvement, described driver element is two magnet, and described two magnet are installed on the driving shaft of drive motor with the corresponding setting of described magnetic stirrer, described two magnet.

Among the present invention, use dilute hydrochloric acid solution, apply DC voltage on every pair of electrode and in cleaning process, control system can be controlled the polarity of the voltage on the electrode is regularly switched as electrolytic solution.
The course of work of the present invention is as follows:
At first four electrode sockets corresponding with control system with electrolytic cell connect, then to the dilute hydrochloric acid solution that wherein adds about 10%, then click " startup " button, control system will start stirring system, drive motor wherein drives two magnet clockwise direction rotations fixing on it, and then drives the magnetic stirrer rotation in the electrolytic cell, and electrolytic solution is wherein also rotated, control system is rotated counterclockwise motor after two minutes, and every exchange in two minutes once; When motor rotated, control system was sent 200mA and 500mA electric current to indicator electrode and electrode electrode respectively, and on the electrode following reaction will take place this moment:
Negative electrode: 2H wherein
++ 2e
-=H
2↑, anode: 2Cl
--2e
-=Cl
2↑, therefore two electrode surfaces constantly produce bubble, constantly washing away of rotating liquid breaks away from the dirt of electrode surface gradually in addition, every control system after 1 minute the positive and negative polarity of the voltage on every pair of electrode is exchanged automatically, make each electrode all obtain cleaning, control system stops operating and electric current after 8 minutes, at last hydrochloric acid solution is emitted and adds distilled water, by "start" button, clean after stopping automatically promptly accusing and finish again.
Owing to adopted above technical scheme, the present invention has following beneficial effect:
Control system of the present invention is provided with four corresponding sockets of electrode with described electrolytic cell, in order to be four electrodes feeding electric currents when cleaning electrode; Described stirring system can make the liquid in the electrolytic cell wash away electrode surface, and cleaning effect is good, and simple to operate, and is time saving and energy saving.
