Description

Technical Field

[0002] With the overall improvement of industrial level, the amount of industrial wastewater generated has gradually increased. In recent years, environmental awareness has continued to increase, and the discharge standards for industrial wastewater have become increasingly higher. Wastewater discharged by industries such as textiles, chemicals, petroleum and electroplating needs to go through multiple wastewater treatment processes before the separated water can meet the discharge standards.

[0003] At present, in the evaporation treatment process of industrial wastewater, a scraper is usually used to scrape off the attachments in the treatment tank to avoid affecting the next use and ensure the service life of the tank. Sometimes, some agents need to be added during the treatment process for auxiliary treatment. The stirring rod is used for stirring, and then the scraper at the end of the stirring rod can scrape the inner wall of the tank. However, it is easy to wear if it rotates against the inner wall for a long time, and it is easy to lose the scraping effect if it does so for a long time. Utility Model Content
