Abstract

The invention provides an apparatus capable of on-line continuous monitoring of the pH value of a water sample and automatic cleaning of an electrode, which relates to the technical field of environmental protection equipment. According to the invention, a hairbrush is connected with a hairbrush cleaning motor; one end of a pH electrode is connected with a rotary actuator; a measuring tank is arranged below the pH electrode; an ultrasonic cleaning tank is arranged at one side of the measuring tank; one end of the ultrasonic cleaning tank is connected with an outlet channel through an overflow weir; the lower end of the measuring tank is connected with an inlet groove; the inlet groove is connected with an inlet pipe; and the measuring tank and the ultrasonic cleaning tank are both connected with a limit stroke switch which is interlocked with a linear motor. With the apparatus, automatic continuous monitoring of a pH value and automatic cleaning are realized, and accuracy of measuring of the pH electrode is improved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a device for continuously monitoring the pH value of water samples on-line and for automatically cleaning electrodes. Background technique [0002] In the process of chemical, metallurgical, manufacturing, printing and dyeing wastewater treatment, in order to meet the requirements of water treatment process, it is necessary to accurately and continuously monitor and control the pH value of each process section. At present, the online monitoring method is adopted in China, or the manual sampling measurement method is adopted. [0003] On-line monitoring method, the main installation methods include: immersion type, lifting type, drainage type, side insertion type, screw-in type, the above monitoring methods have many disadvantages; for example, due to the high calcium and magnesium ions in industrial wastewater, the pH probe is easy to scale, PH value ...
