Automotive adsorptive type oil filter

Abstract

The invention belongs to the technical field of automobile fittings, and particularly relates to an automobile adsorptive type oil filter. The oil filter includes a shell, a guide pipe, a filter element, a base, a motor, a stand column, a gear and a gear ring. The upper surface of the guide pipe is vertically provided with an oil in channel in the axial direction, the outer surface of the portion,in the shell, of the guide pipe is provided with an oil through hole, and the guide pipe is vertically provided with a spiral sheet in the oil in channel. The filter element is of an annular structure and used for filtering oil flowing out from the oil through hole. The base is located in the shell, and the lower end of the guide pipe is rotatably installed on the base through a bearing. The lower end of the stand column is fixed on the base, and the upper end of the stand column is located in a T-shaped annular groove of the shell through a T-shaped block to achieve connection of the stand column and the shell. The gear is horizontally and fixedly installed on the guide pipe and located above the filter element. The gear ring is fixedly installed on the stand column, and the gear is located in the gear ring and fully meshed with the gear ring circumferentially. The oil fiter can remove scrap iron impurities in oil and the filtering effect is better.

Description

technical field [0001] The invention belongs to the technical field of auto parts, in particular to an adsorption type oil filter for automobiles. Background technique [0002] In order to remove the impurities in the engine oil, to ensure the stable and reliable operation of the engine, and to increase the service life of the moving parts of the engine, most automobile engines install an oil filter on the engine to filter the oil, but many filters are The performance is not very stable when used, and it is easy to block when filtering, resulting in poor use of the filter, and the filter can only filter out impurities with large particle sizes, and it is difficult to filter out abrasive impurities with small particle sizes. At the same time, it is also difficult to remove some impurities such as iron filings, it is difficult to improve the filtering effect of the filter, and the service life of the filter element is shortened.

Problems solved by technology

[0004] In the above-mentioned patent documents, the removal of iron filings impurities in the engine oil is achieved by setting a magnetic body. At the same time, the filter element can be easily replaced by tightening the nut. However, the filtering capacity of the filter element in this solution cannot be improved. The magnetic body is fixed in the housing, so the effective adsorption range is limited, and the adsorption effect of iron filings in the oil is not good
