An oil filter device

Abstract

The invention belongs to the technical field of vehicle parts, and particularly relates to an engine oil filtering device. The engine oil filtering device comprises a shell, an end cover, a first clapboard, a second clapboard and a third clapboard, the end cover and the first clapboard constitute an oil inlet cavity, and a first filtering cavity, a second filtering cavity and a third filtering cavity are formed in the shell from top to bottom in sequence; two filtering plates are symmetrically arranged in the first filtering cavity, and a first air cylinder is arranged between the two filtering plates; stirring modules are arranged at the outer sides of the filtering plates, and used for stirring engine oil. According to the engine oil filtering device, by introducing the engine oil into the oil inlet cavity, and utilizing the first filtering cavity, the second filtering cavity and the third filtering cavity for conducting layer-by-layer filtering on the engine oil, the effect of filtering the engine oil is improved; meanwhile, the stirring modules are arranged and used for stirring the engine oil fallen into first through holes, the speed at which the engine oil penetrates throughfirst filtering nets is increased, and the efficiency of filtering the engine oil is improved; moreover, through the arrangement of a first one-way filtering net and a second one-way filtering net, the engine oil is prevented from flowing back.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an engine oil filter device. 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. The oil filter should have strong filtering ability, small flow resistance and long service life. At present, the existing oil filter includes a casing with an inner cavity, an oil inlet pipe and an oil outlet pipe connected to the inner cavity of the casing, and a filter element assembly is arranged in the inner cavity of the casing, and the filter element assembly includes a paper core, a paper core The upper cover, the base of the paper core, the paper core is set betwee...
