Description

Technical Field

[0001] The utility model belongs to the technical field of lubrication accessories and relates to a lubricating oil filter component. Background Art

[0002] Lubrication system contamination refers to the presence of a considerable amount of impurities in the lubricating oil. These impurities are generally metal chips generated by wear and aging of machine parts and chemical reactions, which affect the lubrication and heat dissipation effects, accelerate the wear of running parts, shorten the life of equipment, damage seals, increase leakage, etc. After working for a long time, the existing lubricating oil filter is prone to blockage as the impurities continue to increase. In this case, the normal operation of the machine is affected by insufficient oil supply, and a filter is needed that can clean or replace the filter without stopping the machine. This requirement can also be achieved by connecting a set of filters in parallel in the piping system, but it will increase manufacturing costs, and the assembly space is limited, so it will inevitably take up a lot of space, which does not meet the use requirements.

[0005] In the above-mentioned lubricating oil filter assembly, the filter unit is a hollow filter cover with filter holes, and the two ends of the filter cover are in contact with the upper shell and the lower shell respectively.

[0006] In the above-mentioned lubricating oil filter assembly, a through hole is provided on the lower end surface of the lower shell, which is axially recessed inward and communicated with the cavity. The lower shell is provided with an assembly block connected to the through hole and for installing the cleaning unit.

[0007] In the above-mentioned lubricating oil filter assembly, the cleaning unit is composed of a cleaning rod and a rotating handle. The cleaning rod is arranged on the rotating handle and connected thereto, and the cleaning rod is provided with a cleaning brush portion connected thereto and convenient for cleaning. The assembly block is provided with a threaded hole that cooperates with the rotating handle. The cleaning rod and the cleaning brush portion are rotated through the threaded hole, thereby achieving cleaning inside the filter cover.

[0008] Compared with the prior art, the lubricating oil filter assembly can clean adhered impurities during operation, thereby ensuring its operating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0012] like Figure 1 As shown, the lubricating oil filter assembly includes a filter housing 1 with an oil inlet channel and an oil outlet channel. The filter housing 1 is composed of an upper housing 2 and a lower housing 3 with a cavity. The above-mentioned oil inlet channel and oil outlet channel are both arranged on the upper housing 2, and the oil inlet channel and the oil outlet channel are connected by splicing the upper housing 2 and the lower housing 3. A filter unit connected to it and used for filtering impurities is provided in the lower housing 3. A cleaning unit that cooperates with the filter unit and is used to prevent impurities from adhering to the filter unit is also provided in the lower housing 3. The filter unit is a filter cover 4 with a filter hole and a hollow setting, and the two ends of the filter cover 4 are respectively in conflict with the upper housing 2 and the lower housing 3. The above-mentioned oil inlet channel is connected to the inside of the filter cover 4. The filter cover 4 consists of an upper shell part and a lower shell part. The above-mentioned filter hole is provided on the lower shell part. The lower housing 3 has a filter hole. A through hole is provided on the lower end face, which is axially recessed inward and communicated with the cavity. The lower shell 3 is provided with an assembly block 5 connected to it and for installing the cleaning unit at the through hole, and the cleaning unit is extended into the filter cover tube 4 through the assembly block 5. The above-mentioned filter cover tube 4 and the assembly block 5 are coaxially arranged. The cleaning unit consists of a cleaning rod 6 and a rotating handle 7.
