Improved engine oil filter

Abstract

The invention provides an improved engine oil filter. The improved engine oil filter comprises a shell and a controller. A partition plate is arranged in the shell, and the inside of the shell is divided by the partition plate into a first chamber and a second chamber. Two through holes are symmetrically formed in the partition plate, and filter nets are arranged at the through holes respectively. First detection devices for detecting the thickness of filter residues on the filter nets are arranged on the filter nets respectively and connected with the controller. A base is arranged on one side, close to the first chamber, of the partition plate, and first cleaning devices are arranged at the portions, close to the through holes, of the base respectively. The first chamber is internally provided with a first filter element, and the inside of the first chamber is divided by the first filter element into a first filter cavity and a second filter cavity. The second chamber is internally provided with a second filter element, and the inside of the second chamber is divided by the second filter element into a third filter cavity and a fourth filter cavity. A second detection device for detecting the thickness of filter residues on the second filter element is arranged on the second filter element and connected with the controller. The fourth filter cavity is internally provided with a second cleaning device. By means of the improved engine oil filter, impurities in engine oil can be filtered out, the using standard of the engine oil can be met, and the filter residues on the filter elements can be easily removed.

Description

technical field [0001] The invention relates to the technical field of engine oil filters, in particular to an improved engine oil filter. Background technique [0002] The main function of the engine oil is to minimize the impurities generated by friction of various components during operation, reduce energy loss and wear of parts. 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, sup...

AI Technical Summary

Problems solved by technology

[0003] 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 To filter the engine oil, the filter area is small, and the bottom of the filter screen acts for a long time, the filter residue is not easy to remove, and it is easy to block, which affects its normal use
