The invention discloses a multistage filtering oil filter. A first filtering element is arranged in a casing to divide an accommodating cavity into a filtering cavity at the upper portion and a liquid outlet cavity at the lower portion, a filtering barrel is vertically arranged in the filtering cavity, a filtering screen structure is arranged on a lateral wall of the filtering barrel, a driving mechanism is connected with the filtering barrel and used for driving the filtering barrel to rotate around a rotating shaft of the driving mechanism, a second filtering element is fixed with the filtering barrel and spirally extends along the filtering barrel, the second filtering element is prepared from a foldable filtering material, and a folding line of the second filtering element is distributed in the radial direction of the filtering barrel. The optimally-designed multistage filtering oil filter has optimal and reasonable structure design; during work, the driving mechanism can drive the filtering screen to drive the second filtering element to rotate, the filtering screen can coarsely filtering machine oil and distribute materials at the same time, and the second filtering element can rotate to filter-press the coarsely-filtered machine oil to an oil inlet; the second filtering element is prepared from the foldable filtering material, so that a filtering area is guaranteed, and solid impurities in the machine oil are effectively removed at the same time; thus, filtering efficiency and a filtering effect are greatly improved.
Description
technical field [0001] The invention relates to the technical field of engine oil filters, in particular to a multistage filter engine oil filter. Background technique [0002] During the working process of the engine, metal wear debris, dust, carbon deposits and colloidal deposits oxidized at high temperatures, water, etc. are continuously mixed into the lubricating oil. The function of the oil filter is to filter out these mechanical impurities and colloids to keep the lubricating oil clean and extend its service life. After the oil filter works for a period of time, it is easy to cause clogging. In order to prevent the engine from being damaged due to lack of oil lubrication, the oil filter in the prior art is provided with a bypass valve to ensure that the oil is blocked when the filter element is blocked. Open the bypass valve to supply unfiltered oil to the engine, thereby reducing engine damage. However, unfiltered engine oil contains impurities such as metal shavin...
