Abstract
The utility model provides a PH (Potential of Hydrogen) electrode washing device, and relates to an online submerged PH electrode washing device. The PH electrode washing device comprises a washing tank (1) and a washing pipe (8), wherein a PH electrode (2) is fixedly sleeved with the washing tank (1); a lateral filter screen (5) is arranged on the lateral face of the washing tank (1), and a bottom filter screen (6) is arranged at the bottom of the washing tank (1); the washing pipe (8) extends into the washing tank (1); a water outlet of the washing pipe (8) and the PH electrode (2) are oppositely arranged. With the adoption of the lateral filter screen, not only can solid impurity particles be filtered, but also the turn volume of measured slurry can be effectively improved. Furthermore, the slurry inside the washing tank is uniformly mixed with the outside slurry, so that the detection precision is improved. The bottom filter screen can form certain resistance for washing water, so that the washing water is prevented from being discharged from the bottom of the washing tank directly, and eddy can be formed inside the washing tank, and therefore, back-washing to the lateral filter screen and the bottom filter screen can be realized due to the eddy, and attachments on the filter screens can be reduced. The accuracy of PH detection is high, and the service life of the PH electrode can be prolonged.
