Description
Technical field
The utility model relates to the cleaning device of pH meter potential electrode, refers to a kind of online pH meter potential electrode automatic flushing device particularly.
Background technology
PH meter is a kind of measuring equipment of measuring industrial pollution water water quality potential of hydrogen.When carrying out the pH value of solution pH-value determination pH with pH meter, the electrical contacts of electrode and solution divides and keeps cleaning is to guarantee acidometer measuring accuracy, sensitivity and stable most important work.But owing to may contain the material that causes electrode fouling in the detected solution, as outstanding absurd creature, jelly, microorganism, grease, chemical reagent, calcium salt and the easy crystal material that forms fouling, topic between one of the pollution of electrode is difficult to avoid.In order to guarantee that pH meter can use for a long time continuously, avoid the contaminated electrode can be inaccurate, and then influence the control input of water quality corrective the measurement of water quality potential of hydrogen, electrode system is cleaned automatically be absolutely necessary.
Cleaning way to the radioactive content electrode has at present:
A. scraper type cleans: during cleaning, by the rotation of driven by motor scraping blade, fouling is all wiped off by scraping blade together with electrode surface, do not need artificial cleaning, still, because electrode tip is to be made by very thin glass, scraper type cleans big to the damage of electrode, and reduce serviceable life, causes use cost big; B. dripping acid cleans: big with the dirt on acid solution lysis electrodes surface to measuring influence, cause misoperation easily; C. manually clean: length consuming time, safeguard that intensity is big.
Summary of the invention
The purpose of this utility model will overcome the existing in prior technology deficiency exactly, and a kind of online pH meter potential electrode automatic flushing device is provided, and utilizes line gas that electrode is cleaned.
For achieving the above object, the online pH meter potential electrode automatic flushing device that the utility model is designed, comprise air-source pump, the draft tube that links to each other with air-source pump, be arranged on the source of the gas pressure regulator valve on the draft tube, and the electrode cleaning device that links to each other with the draft tube output terminal, described electrode cleaning device comprises the equal trim ring pipe of source of the gas, jet source of the gas pipe and jet circle, the equal trim ring pipe of described source of the gas links to each other with the output terminal of draft tube, one end of described jet source of the gas pipe links to each other with the equal trim ring pipe of source of the gas, the other end of described jet source of the gas pipe links to each other with the jet circle, and the inboard of described jet circle evenly is provided with a plurality of jet orifices.
Particularly, the wall thickness of described jet circle is 3～5mm.
Preferably, the quantity of described jet orifice is 20～30, and the aperture of described jet orifice is 1.5～2mm.Like this, can guarantee that line gas directly is ejected on the contaminated electrode equably, with the quality that guarantees to clean.
Preferably, described draft tube is provided with the bleed pressure table.The output pressure of described air-source pump is 0.1～0.2MPa.Like this, the stream pressure of output is visual, can avoid the excessive influence to electrode life of pressure, and the too small influence to cleaning performance of pressure.
The beneficial effects of the utility model are: the utility model adopts the gas jet mode to clean, and the cleaning of electrode and measurement can be carried out simultaneously, need not pH meter is taken out independent cleaning electrode.When line gas cleaned electrode, air-flow can form the measured medium around the potential electrode and stir, and makes the measured medium ingredient even, thereby improves the accuracy of electrode measurement.The utility model is cleaning electrode not only, also can improve the accuracy of electrode measurement.The utility model adopts the gas jet mode to clean, and is easy to use, little to the damage of electrode, the serviceable life of improving equipment, thus reduce use cost, reduce to safeguard intensity.
