Filter element and filter comprising filter element

Abstract

A filter element comprises a core. The core comprises an inner pipe and an outer pipe which are coaxially arranged. Evenly-distributed filter holes are formed in the pipe walls of the inner pipe and the outer pipe. A circle of inner filter net is attached to the outer wall of the inner pipe. A circle of outer filter net is attached to the inner wall of the outer pipe. The part between the outer filter net and the inner filter net is filled with filter materials, wherein the filter materials are manufactured through plant fiber containing a low-zinc-value additive. A plurality of annular isolation pads for isolating the filter materials are arranged between the outer filter net and the inner filter net. The filter materials are manufactured through the plant fiber, so that cost is low; after the low-zinc-value additive is added, the physicochemical indexes of online lubricating oil can be stabilized for a long time through the filter materials, and the service life of the online lubricating oil is effectively prolonged. In addition, through the isolation pads, stacking of the filter materials due to gravity can be prevented, the filter element is not prone to blockage, accordingly,the service life of the filter element is prolonged, and frequent filter element replacement is not needed. In addition, the invention further provides a filter comprising the filter element.

Description

technical field [0001] The invention relates to the technical field of automobile filters, in particular to a filter element and a filter containing the filter element. Background technique [0002] The oil filter plays a very important role in the lubrication system of the car. It can filter out impurities such as metal wear debris, carbon particles and colloids gradually produced by the engine oil during the combustion process of the engine and mixed into the oil, thereby Ensure the normal operation of the engine and improve the service life of the engine. [0003] At present, the commonly used oil filter includes compression spring, filter paper, anti-drain valve, pressure ring, sealing ring, oil inlet, oil outlet, cover plate, filter element central tube support structure, metal shell, and its core components are A filter core made of filter paper with a folded structure. Its working principle is: when the engine oil pumped out from the oil pan by the oil pump enters t...

AI Technical Summary

Problems solved by technology

The filter element of the existing filter is generally a paper structure, which is prone to clogging with the increase of impurities. Generally, the filter needs to be replaced after every 5000-10000 kilometers of the car, which makes the replacement of the filter more frequent
