Problems solved by technology

In systems such as activated sludge tanks at the entrance and exit of sewage treatment plants, neutralization tanks in wastewater treatment plants, and variable-porosity filters in municipal reclaimed water, there are many water quality pollutants, which are easy to contaminate electrodes, and the frequency of electrode cleaning is very high.
At the same time, it is difficult to ensure that the electrode is always immersed in the measured solution due to the uncertainty of the change of the liquid level of the measurement medium. In actual use, many managers need to continuously track and check the use of the instrument, and the amount of daily maintenance is relatively large.

Embodiment 1

[0033] 1. Data collection: Determine the electrode insertion level according to the level switch on the electrode mount.

[0034] 2. Parameter setting: Set the cleaning cycle, rinse time, cleaning time, and stability time parameters of the electrode automatic cleaning unit through the man-machine dialogue operation keyboard connected with the micro-processing. The cleaning mode can be selected between automatic and manual modes. In manual mode, press the start button to enter the cleaning program; in automatic mode, set the cleaning cycle, and the cycle time is up, and the cleaning program will automatically enter.

[0035] 3. Analysis and calculation: Analysis of the lifting action of the electrode automatic lifting device: operating condition 1, insert the liquid level alarm value through the electrode, when the liquid level is low, it is concluded that the electrode is exposed to the air, and the electrode automatic lifting device needs to be lowered Instruction, when the liquid...

Embodiment 2

[0039] On the basis of method embodiment 1, set the electrode cleaning judgment program after the step analysis and calculation. In the electrode cleaning program, set the electrode running cleaning cycle value, water rinse value time value, cleaning time value, and stable time value in advance, according to the water quality In case of cleaning effect, the operator corrects the set parameter value.

[0040] The microprocessor of the present invention adopts the 32-bit ARM main control chip LPC1752. The LPC1752 chip has fast operation speed, high cost performance, and provides abundant common peripheral interfaces, which can provide good system device functions. The storage unit of the microprocessor includes an EEPROM data memory, which is mainly composed of a piece of CAT24C256, which is used to store historical data of the control system, store status data and process alarm information. Liquid level switch, used to measure the high and low switching signal of the medium liquid...

Abstract

The invention provides an input type automatic PH glass electrode adjusting device and method. An automatic electrode cleaning device and an automatic electrode lifting device are adopted, an electrode measuring device can be automatically controlled to be maintained and cleaned, measurement accuracy is ensured, the depth of the portion, immersed into a measuring medium, of the electrode measuring device can be automatically controlled, measuring points can be automatically adjusted according to liquid level changes, the measurement continuity is ensured, and the phenomenon that an electrode is exposed in air due to liquid level changes of the measuring medium is avoided.

Description

Technical field [0001] The invention belongs to the technical field of environmental protection, and specifically relates to an input type PH glass electrode automatic adjustment device and method. Background technique [0002] Industrial PH meters are widely used in waste water treatment systems. The use of industrial PH meters largely depends on the maintenance of electrodes. First of all, the electrode should be cleaned frequently to ensure that it is not contaminated. Secondly, no matter in the reaction process or after discharging, ensure that the electrode is immersed in the test solution to ensure that the electrode is in a wet state; at the same time, the cable connector must be kept clean. Moisture or water ingress. In systems such as the inlet and outlet activated sludge tanks of sewage treatment plants, the neutralization tanks of wastewater treatment plants, and municipal reclaimed water variable pore filter tanks, there are many water quality pollutants, which easil...
