Description

Technical Field

[0001] The invention relates to the technical field of sewage detection, and in particular to an automatic cleaning probe device. Background Art

[0002] In modern sewage treatment, monitoring and controlling water quality is an important part of ensuring treatment effects and environmental protection requirements. pH probes, MLSS (mixed liquor suspended solids) probes and other equipment are usually used for real-time monitoring. However, the sewage treatment environment is complex and highly corrosive. After being immersed in sewage for a long time, these probes are prone to scaling and contamination, affecting the accuracy and reliability of measurement data.

[0003] At present, the cleaning of probes mostly relies on manual operation, and the staff needs to regularly remove the probes from the sewage for cleaning. This method not only increases labor costs, but also has certain safety hazards in the cleaning process in some dangerous environments such as Fenton reaction towers. In addition, due to untimely or incomplete manual cleaning, it may also cause probe data deviation, thus affecting the operation effect of the entire sewage treatment system.

[0004] The common automatic cleaning devices on the market are all underwater. This method has some disadvantages and limitations: (1) The cleaning effect is not thorough enough; (2) The water consumption is large; (3) It causes secondary pollution; (4) The energy consumption is large; (5) The equipment is severely corroded and difficult to maintain.

[0005] The current manual cleaning method has the following defects: (1) High cost of manual cleaning: In the prior art, the cleaning of the probe mainly relies on manual operation, which requires a lot of human resources and increases operating costs; (2) Safety hazards: In some dangerous sewage treatment environments, such as high temperature and highly corrosive Fenton reaction towers, manual cleaning of the probe poses a great safety hazard and increases operational risks; (3) Untimely cleaning: The frequency and timing of manual cleaning are difficult to accurately control, which may lead to untimely cleaning, resulting in serious scaling of the probe, affecting the accuracy of the data and the effect of sewage treatment; (4) Unstable cleaning effect: Due to the influence of human factors, the effect of manual cleaning is uncertain, and incomplete cleaning may occur, resulting in residual pollutants in the probe during use, affecting the measurement results.
