Abstract

The invention relates to the technical field of oil filtering devices, and discloses an external oil filter, which includes an outer cylinder, a central cylinder, a filter sleeve, a first guide disc, a second guide disc and a magnetic strip ring. There is a central cylinder, a filter sleeve is provided outside the central cylinder, a dislocation baffle is provided on the inner wall of the outer cylinder, a second guide disc is provided on the upper part of the filter sleeve, a first guide disc is provided on the outer wall of the second guide disc, and a second guide disc is provided on the outer wall of the second guide disc. There is a magnetic ring on the outer wall of the bottom of the disk; the present invention establishes the initial path of the oil through the drainage of the upper ring, the first guide disk and the second guide disk. The ferromagnetic impurities are adsorbed for the first time, and then the ferromagnetic impurities are adsorbed by the magnetic ring for the second time. The impurity precipitation is completed during the overflow process of the oil in the circuitous tank, and then the oil is evenly distributed step by step under the action of the misplaced baffle, and the multi-stage ferromagnetic impurities are filtered. Yes, the overall filter element is evenly filtered, the filtration efficiency is good, and the oil discharge is smooth.

Description

technical field [0001] The invention relates to the technical field of oil filter devices, in particular to an external oil filter. Background technique [0002] The oil filter, also known as the oil grid, is used to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil to protect the engine. The oil filter is divided into full flow and split flow. The full-flow filter is connected in series between the oil pump and the main oil passage, so it can filter all the lubricating oil entering the main oil passage. The diverter filter is connected in parallel with the main oil passage to filter only part of the lubricating oil sent by the oil pump. [0003] The current oil filter relies on the filter element holes to intercept and filter out harmful impurities in the oil. The smaller the pores of the filter paper, the better the filtering effect, but the worse the oil passing ability. In order to solve the contradiction that the smallest p...
