Lubricating oil impurity removal device for synthetic gasoline engine

The utility model discloses an impurity removal device for lubricating oil of a synthetic gasoline engine, relates to the technical field of lubricating oil processing, and solves the problems that the existing filter element is positioned inside the impurity removal device, is inconvenient to disassemble and assemble when being used for cleaning impurities, is difficult to clean at a deeper impurity filtering part, and is inconvenient to clean. And accumulation of a large amount of impurities can reduce the impurity removal efficiency of the lubricating oil. Comprising an impurity removing box, two liquid discharging pipes are fixedly connected into the impurity removing box in a sleeved mode, the two liquid discharging pipes are symmetrically distributed with the axis of the impurity removing box as the center, two sleeving frames are fixedly connected into the impurity removing box in a sleeved mode, and rotating shaft round rods are fixedly connected into the two sleeving frames in a sleeved mode; accordi
