[0002] In the process of oil-containing sewage treatment, slag scraping on the sewage treatment device is an important link, mainly used to remove floating slag, grease and other impurities on the water surface to ensure the smooth progress of subsequent treatment processes. Traditional slag scraping methods mostly use rotary chain plate slag scraping devices. In the actual operation process, the following disadvantages exist:

[0003] 1. Complex structure: The structure of the traditional rotary chain plate slag scraper is usually relatively complex, including multiple components and assemblies, such as a driving device, a transmission chain, a sprocket, a scraper plate, etc. This complexity may lead to an increase in maintenance and repair costs, and at the same time, it also increases the probability of failures.

[0004] 2. Complicated operation: Due to its complex structure, the operation of the traditional rotary chain plate slag scraper may also be relatively complicated, which may require more operators and maintenance personnel, increasing the labor cost and having a low working efficiency at the same time.

[0005] 3. Limited slag scraping efficiency: Factors such as the moving speed of the scraper plate supporting the traditional rotary chain plate slag scraper and the disturbance of the sewage may affect the slag scraping effect.

[0006] 4. High energy consumption: Due to its operation mode and working principle, the traditional rotary chain plate slag scraper needs to consume a large amount of energy, which increases the operation cost.

[0007] Therefore, it is necessary to develop a slag scraping device with a simple structure, convenient operation, high slag scraping efficiency and easy maintenance. Summary of the Invention
