[0002] Lubricating oil is a technology-intensive product, which is a mixture of complex hydrocarbons, and its true service performance is the comprehensive effect of complex physical or chemical change processes. When lubricating oil is used, it is usually an oily liquid applied to the surface of moving parts such as machine bearings or certain parts of mechanical equipment, which has the effects of reducing friction, avoiding heat generation, and preventing machine wear. During the production process of lubricating oil, in order to reduce the impurities inside the lubricating oil and ensure the quality of the lubricating oil, a filtering device is usually required to filter the lubricating oil.

[0003] For the filtering devices used in the production process of existing lubricating oil, since the impurities in the lubricating oil are usually very small in particles, in order to ensure the quality of the lubricating oil, a filter screen with an extremely small pore size needs to be used, which results in frequent blockage of the filter screen of the filtering device and reduces the filtering efficiency. In the prior art, because the filter screen cannot be automatically cleaned and manual cleaning is troublesome, it is usually necessary to wait until the blockage is serious and the normal operation cannot be carried out before manual cleaning, resulting in low filtering efficiency. Content of the Utility Model
