AI Technical Summary
In existing lubricating oil production and blending equipment, raw materials tend to adhere to the inner wall of the tank during the mixing process, making them difficult to scrape off, resulting in uneven mixing. Furthermore, the existing vertical scraper strips are not very effective at removing the raw materials.
A spiral scraper is installed on the outside of the mixing assembly, closely adhering to the inner wall of the tank and rotating synchronously to scrape off the adhering lubricating oil mixture and convey it to the bottom of the tank through a hopper-shaped bottom, thereby cleaning the inner wall of the tank.
This allows for more precise blending of lubricating oil, ensuring a clean inner wall of the tank and improving the uniformity and accuracy of mixing.
