When mixing emulsions in existing drilling fluid mixing equipment, the emulsions tend to stick to the inner wall of the material tank, resulting in uneven mixing and difficulty in cleaning.
An adjustable drilling fluid mixing device was designed, which adopts a shaft and scraper structure. The shaft is equipped with a mixing rod, and the scraper is connected to the shaft through an electric actuator. When the scraper rotates, it adheres to the inner wall to scrape off the adhering drilling fluid, ensuring uniform mixing and cleaning of the inner wall.
This achieves thorough mixing of the drilling fluid and cleaning of the inner wall, ensuring the quality of the drilling fluid and reducing the rotational resistance during the stirring process.
