Abstract

The filter element comprises a filter element body, a sealing cover, a non-return device, a bypass valve, a shell cover, an oil inlet hole, an oil outlet and a shell, the lower end of a baffle is rotationally connected with a sliding groove, the upper end of the baffle is hinged to a supporting rod, the right end of the supporting rod is hinged to the upper end of a sliding block, and the right end of the sliding block is fixedly connected with a first spring; according to the engine oil filter, engine oil enters from the oil inlet hole, when the engine oil enters, the engine oil pushes the baffle to move rightwards, the engine oil is preliminarily filtered through the filter screen and enters the filter element, when the filter element is blocked, the engine oil enters the oil outlet from the bypass valve, the engine oil compression partition plate moves, and the engine oil is compressed through the filter screen. The engine oil flows into the oil outlet from the upper end of the fixed shell, so that the filter element is effectively prevented from being blocked to influence the working process, and the check device can effectively prevent the engine oil from flowing back.

Description

technical field [0001] The invention relates to the technical field of filter elements, in particular to a filter element for a waste diesel and engine oil filtering device. Background technique [0002] At present, after the lubricating oil of the engine has been working for a period of time, there will be metal shavings and other impurities generated by the friction of engine parts; in addition, foreign impurities, such as dust in the air, enter the crankcase through the breathing pipe, oil filler, etc.; As well as the colloids produced by the engine oil itself, the products of the oxidation process of the engine oil itself, such as various organic acids, coke pitch and carbides, will enter the lubricating oil passage with the engine oil. These impurities will promote the wear of parts, corrode parts or seize moving parts. Therefore, an oil filter must be added in the lubrication system of the engine to filter out the above-mentioned harmful impurities present in the oil,...
