Embodiment Construction

[0015] The automatic cleaning mechanism of pH meter of the present invention, its preferred embodiment is:

[0016] Including a connecting rod, the lower end of the connecting rod is connected with a pH electrode, and the connecting rod is connected with an actuator for driving the rising or falling of the connecting rod;

[0017] It also includes a cleaning bucket, the cleaning bucket is connected with a flushing water pipe, and a through hole is opened at the bottom of the cleaning bucket;

[0018] When the connecting rod rises to a high position, the pH electrode is located in the cleaning bucket; when the connecting rod is lowered, the pH electrode protrudes downward through the through hole at the bottom of the cleaning bucket.

[0019] The outside of the pH electrode can be provided with an electrode sheath, and the upper end of the electrode sheath is connected to the connecting rod;

[0020] The lower end of the electrode sheath is connected with a sealing block, and ...

Abstract

The invention discloses an automatic cleaning mechanism of a pH meter, comprising a connecting rod, wherein a pH electrode is arranged at the bottom of the connecting rod; an electrode signal wire passes through the connecting rod and is accessed into a special instrument; an electrode sheathing is connected with the connecting rod; and a sealing block is connected with the electrode sheathing. Through the action of an actuating mechanism, a pH electrode connected with the connecting rod is ascended and descended so as to achieve the purpose of separating the pH electrode from the liquid level for cleaning and maintaining or sinking into the liquid level to measure a measured medium. The special instrument can display a measurement result and control an electromagnetic valve and a water valve so as to realize the lifting control and the cleaning control of the pH electrode. The invention has the advantages of good cleaning and maintaining effects on the pH electrode, simple structure, safety, reliability, wide application range, service life extension of the pH electrode, and the like.

Description

technical field [0001] The invention relates to a pH value detection device, in particular to an automatic cleaning mechanism of a pH meter. Background technique [0002] The pH meter is an important analytical instrument in the industrial production process, which is of great significance for guiding the improvement of the process flow and improving the quality of the product. [0003] In mineral processing, metallurgy, chemical industry, water treatment and other industries, the composition of the measured medium is complex, and the pH electrode is easily polluted, mainly manifested as calcium accumulation; some use environments are severely worn, resulting in short service life of the electrode; in strong corrosive environments Under these conditions, the pH electrode will be corroded again. In the industrial process, there will be one or more of the above situations such as easy calcium formation, strong abrasion, strong corrosion, etc., resulting in increased pH measur...
