Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil production, and more particularly to a lubricating oil filter used in lubricating oil production. Background Art

[0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. When impurities such as particulate matter are mixed in the lubricating oil, not only will the lubricating ability of the lubricating oil be reduced, but the impurities such as particulate matter will also cause wear between the moving surfaces of the machinery lubricated by the lubricating oil, thereby reducing the mechanical performance of the lubricated equipment. Therefore, during the production process of lubricating oil, it is necessary to use a filter to filter the lubricating oil to make the lubricating oil purer.

[0003] A lubricating oil filter for lubricating oil production with announcement number CN219701335U includes a shaking assembly arranged inside the filter box. The shaking assembly includes a filter box arranged inside the filter box and a connecting piece symmetrically arranged on the surface of the filter box, which is conducive to making the filter box move back and forth in the left and right horizontal directions, thereby improving the filtration speed of the filter box, and then improving the filtration efficiency of the device, which is conducive to stirring impurities on the surface of the filter box and reducing the probability of impurities accumulating in the filter holes of the filter box.

[0004] In actual use, the lubricating oil filter proposed in the aforementioned patent document has a horizontally placed filter screen inside the filter box. This not only results in insufficient contact between the filter screen and the lubricating oil, thus affecting filtration efficiency, but also increases the likelihood of lubricating oil impurities accumulating on the filter screen surface, causing blockage. Furthermore, the filter cannot achieve automatic circulation filtration, reducing the lubricating oil filtration efficiency. Therefore, improvements are needed to address these existing issues.
