Filtering cyclone separation device for removing impurities in waste lubricating oil

The utility model relates to a filtering cyclone separation device for removing impurities in waste lubricating oil. The filtering cyclone separation device comprises a filtering part and a cyclone separation part, the filter part comprises a magnetic filter cone, a filter screen, a longitudinal pipe, a bent pipe and a tangential pipe; the magnetic filter cone is located above the cyclone separation part, and the filter screen is detachably connected to the interior of the magnetic filter cone; the longitudinal pipe is fixedly connected to the bottom end of the magnetic filter cone and is communicated with the magnetic filter cone; the bent pipe is in an arc shape and is communicated with the longitudinal pipe, and the bent pipe is tangent to the longitudinal pipe. The waste lubricating oil can be subjected to primary filtration and impurity removal before being subjected to cyclone separation, so that scrap iron and large-volume solid impurities mixed in the waste lubricating oil are removed, and damage caus
