Description

A double-layer sealed leak-proof oil filter

Technical Field

The utility model relates to the technical field of oil filters, in particular to a double-layer sealed and leak-proof oil filter.

Background Art

Before oil media such as fuel and lubricating oil enter automobile-related equipment, impurities in the oil products must be filtered. Therefore, oil filters that play a filtering role are generally set at appropriate locations. The filter screen of the oil filter is the main component that plays a filtering role. The oil filter belongs to the pipeline coarse filter series and can also be used for filtering large particles in gas or other media. When installed on the pipeline, it can remove larger solid impurities in the fluid to prevent it from affecting the normal use of the equipment, so that the machinery and equipment (including compressors, pumps, etc.) and instruments can work and operate normally, achieve a stable process, and ensure safe production. The efficient oil filter can make the impurities in the oil more fully removed to avoid affecting the normal use of the equipment due to oil quality problems;

A Chinese patent publication (publication number: CN211912940U) discloses a detachable and washable oil filter, which includes a circular bottom plate, a bottom groove is provided on the inner side of the circular edge of the circular bottom plate; three closely attached cylinders are embedded in the bottom groove, the three cylinders are respectively a steel wire mesh near the inside, a filter mesh in the middle, and an outer cylinder body, and water outlets are distributed on the outer cylinder body; two upper pressing long plates are arranged above the three cylinders, intersecting vertically to form a cross shape; arc-shaped grooves are provided at both ends of each upper pressing long plate, and the arc-shaped grooves are embedded downwardly in the top edges of the three cylinders; an upper bolt opening is provided at the intersection of the two upper pressing long plates The circular bottom plate is provided with a lower bolt opening at a vertically corresponding position of the upper bolt opening, and the two ends of a bolt pass through the upper bolt opening and the lower bolt opening respectively and are locked by a nut; although the utility model can facilitate the removal, cleaning and replacement of the filter screen while realizing effective filtration of oil media such as fuel and lubricating oil, in actual use, the single-layer oil filter housing has a relatively simple filtering component, and impurities generated by filtration are easy to accumulate, which needs to be cleaned frequently to avoid affecting the operation of the equipment, bringing inconvenience to users and increasing the labor intensity of users. Therefore, a double-layer sealed and leak-proof oil filter is proposed.
