Environment-friendly engine oil filter

Abstract

The invention discloses an environment-friendly engine oil filter. The environment-friendly engine oil filter comprises a shell body, a filter element is installed in the shell body, an engine oil channel is formed between the filter element and the shell body, an upper cover is installed at the upper end of the shell body, an oil inlet and an oil outlet are formed on the upper cover, the oil inlet communicates with the engine oil channel, the oil outlet communicates with the interior of the filter element, and the lower end of the shell body is provided with a lower cover; the shell body is of a double-layer structure and comprises an inner shell body and an outer shell body, and the inner shell body protrudes outwards to form a reinforcing structure capable of storing impurities; a stirring and decontamination device is installed in the engine oil channel, and an impurity storage chamber is arranged at the lower end of the shell body; and the filter element comprises a piece of filter paper and a filter bag, wherein the filter paper is installed on the upper part of the filter bag, and the filter bag is filled with filter sand. According to the engine oil filter, the shell body is high in strength and not prone to deformation, the filter is provided with a plurality of chambers for storing the impurities, so that the interior of the filter is not prone to blockage, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of automobile filters, in particular to an environment-friendly 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. The oil filter should have strong filtering ability, small flow resistance and long service life. The existing oil filter has the following disadvantages: ①The shell is variable, and the shell is subject to collision variability during use or production and handling; ②As the use time increases, the sundries in the oil filter The more they gather, the more they will easily cause the internal blockage of the filter, which will affect the normal fuel supp...
