Anti-blockage engine oil filter for automobile

Abstract

The invention provides an anti-blockage engine oil filter for an automobile. The anti-blockage engine oil filter comprises a shell, a bottom plate and a transverse partition plate. The transverse partition plate is arranged in the shell and divides the interior of the shell into a first filtering cavity and a second filtering cavity. The transverse partition plate is provided with a first oil conducting port communicating with the first filtering cavity and the second filtering cavity, and a plurality of first through holes communicating with the first filtering cavity and the second filtering cavity. A first filter element is arranged in the first filtering cavity, an annular containing cavity is formed in a second barrel of the first filter element, and the annular containing cavity is filled with metal impurity adsorption materials. The second filtering cavity is internally provided with a second filter element, a bypass valve is arranged on a second end cover of the second filter element, an inlet of the bypass valve communicates with the second filtering cavity, and an outlet of the bypass valve communicates with an inner cavity of a third barrel. According to the anti-blockage engine oil filter, the metal impurity adsorption materials are used for adsorbing and filtering out large-particle metal impurities in engine oil, the filtering pressure of filter paper is reduced, the using cycle of the second filter element is prolonged, and the filtering effect of the second filter element is improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an anti-clogging engine oil filter for automobiles. Background technique [0002] After the engine has been working for a long time, a large amount of iron filings and other abrasives will be produced, and these abrasives will enter the engine oil. Therefore, this part of the recycled engine oil must be filtered so that the recycled engine oil after removing impurities can be reused. At present, the engine oil used in automobile engines is generally filtered through a filter. Its function is to remove impurities such as dust, carbon deposits and soot particles in the engine oil, especially metal particles such as iron filings, so as to ensure that clean engine oil is supplied to the crankshaft, Connecting rods, camshafts, superchargers, piston rings and other moving pairs enable the oil to lubricate, cool, and clean, thereby prolonging the life of these parts. Therefore, the per...

Problems solved by technology

The filter element of the existing oil filter is generally a filter screen. When filtering the oil, the oil is passed into the filter screen, and the impurities are left on the bottom surface of the filter screen. During the filtering process, only the bottom surface of the filter screen Filter the engine oil, metal particles such as iron filings are easy to block the filter screen, making the filter filter efficiency low, affecting the performance and service life of the engine
