Description

Technical Field

[0001] The utility model relates to the technical field of filter devices, in particular to a lubricating oil filter device. Background Art

[0002] When a mechanical structure or device is working, lubricating oil is usually filled between parts to reduce friction, reduce wear between parts, and extend the service life of parts. When impurities such as particles are mixed in the lubricating oil, not only will the lubricating ability of the lubricating oil decrease, but the particles and impurities in the lubricating oil will cause wear on the surface of the parts, thereby reducing the mechanical properties of the lubricated parts.

[0003] When the existing lubricating oil filtering device is used for a long time for filtering lubricating oil, certain foreign particles will accumulate and clog the surface of the filter assembly, causing the filter assembly to affect the lubricating oil filtering efficiency when used for a long time. For this reason, we propose a lubricating oil filtering device. Utility Model Content

[0010] Preferably, when the driving screw shaft is driven to rotate, the pressure plate on the outer periphery of the movable collar cooperates with the limiting rod to limit the lubricating oil inside the inner filter cartridge in an up and down sliding and squeezing state.

[0011] The utility model provides a lubricating oil filtering device, which has the following beneficial effects:

[0012] (1) A lubricating oil filtering device, in this article, after the lubricating oil is injected into the inner filter cartridge, the motor will drive the sleeve part of the driving screw shaft to rotate when it is started, and a cleaning brush is arranged on the outer side of the sleeve part through the support frame. At this time, the support frame can drive the cleaning brush to rotate and rub the inner side of the inner filter cartridge to clean the foreign particles attached to and blocked by the filter screen inside the inner filter cartridge, thereby ensuring the normal filtration and use of the lubricating oil, thereby achieving the effect of improving the filtration efficiency of the lubricating oil.
