Description

Technical Field

[0001] This utility model relates to the field of vacuum oil filtration technology, and more specifically, to a fully automatic vacuum oil filtration machine. Background Technology

[0002] An oil filter is a mechanical device used to remove impurities, moisture, gases, and harmful chemical components from liquids. For example, the lubricating oil filter disclosed in publication number "CN211357872U" includes a coarse filtration device, a fine filtration device, and an oil outlet pipe. The coarse filtration device includes a coarse filter tank body, with a first filter screen that can rotate around its axis and is cylindrical at the upper end of the coarse filter tank body. Multiple cleaning brushes with bristles in contact with the outer wall of the first filter screen are circumferentially installed on the inner wall of the coarse filter tank body. The fine filtration device includes a fine filter tank body, with a third filter screen located in the middle of the fine filter tank body. The third filter screen has two layers, consisting of an inner cylindrical filter screen and an outer cup-shaped filter screen. A cleaning component that can rotate around its axis is located within the inner cylindrical filter screen of the third filter screen. The cleaning component includes multiple circumferentially arranged brushes with bristles in contact with the inner wall of the inner cylindrical filter screen.

[0003] However, the above-mentioned lubricating oil filter lacks an intelligent control structure, which makes it impossible to automatically monitor and provide feedback on key process parameters during operation. Therefore, the entire workflow of the equipment, including the judgment of start-up, shutdown, heating, and dehydration cycles, is highly dependent on the experience and manual intervention of the operators. This not only results in low work efficiency and difficulty in ensuring the stability and consistency of oil purification, but also makes it impossible to achieve truly efficient, unattended, and automatic operation.
