[0002] The primary function of a lubricating oil filter is to filter impurities generated during the lubricating oil circulation process. A qualified filter's effectiveness is primarily considered from two perspectives: first, the cleanliness of the filtered lubricating oil, and second, the outlet pressure. Currently, there are many types of filters on the market, each with a vastly different function. Under certain operating conditions, a single-stage filter relying solely on filter element filtration may struggle to meet its filtration capacity. While a multi-stage filter can meet filtration capacity, it cannot meet outlet pressure requirements, adding unnecessary costs. Utility Model Content

[0027] like Figure 2 As shown, the filter cartridge barrel 10 is also provided with a partition 12 that seals the filter cartridge barrel 10 so that the lubricating oil must pass through the filter cartridge 13. The partition 12 is used to seal the filter cartridge barrel 10 so that the lubricating oil can only enter through the filter cartridge 13. The partition 12 is provided with a connecting port with the same size as the inlet size of the filter cartridge 13, which is used to connect with the filter cartridge 13 to achieve the filtering effect, and a retaining frame 14 is provided in the filter cartridge barrel 10 to fix the filter cartridge 13. The retaining frame 14 is used to connect and fix all the filter cartridges 13. A filter cartridge socket 11 is provided on the partition 12. The filter cartridge socket 11 is used to seal the filter cartridge 13 to the partition 12, which is used to connect the partition 12 and the filter cartridge 13.

The oil drain valve 8 is used to open and discharge the waste oil in the sedimentation barrel 9. The sedimentation barrel 9 is also provided with a bracket 6 for supporting the sedimentation type single-stage filter. The bracket 6 is used to support the entire sedimentation type single-stage filter.

[0029] As shown above, this embodiment is a sedimentation-type single-stage filter for filtering lubricating oil, comprising: an outer barrel 4, an input end of which is provided with an inlet 3, and an output end thereof is provided with a sedimentation barrel 9, the outer barrel 4 is used to introduce the lubricating oil into the sedimentation barrel 9, the filter element barrel 10 is also provided with a partition 12 that seals the filter element barrel 10 so that the lubricating oil must pass through the filter element 13, and a retaining frame 14 is provided in the filter element barrel 10 to fix the filter element 13, a filter element socket 11 is provided on the partition 12, which is used to connect the partition 12 and the filter element 13, the filter element barrel 10 is also provided with a partition 12 that seals the filter element barrel 10 so that the lubricating oil must pass through the filter element 13, and a retaining frame 14 is provided in the filter element barrel 10 to fix the filter element 13, a filter element socket 11 is provided on the partition 12, which is used to connect the partition 12 and the filter element 13, and an outlet 15 is provided on the output end of the filter element barrel 10 to discharge the filtered lubricating oil.

[0030] When the lubricating oil enters the filter, it first flows into the sedimentation barrel 9 through the outer barrel 4, then continues to rise and flows into the filter element 13 from the filter element socket 11 on the partition 12, and then flows out from the filter outlet 15 after being filtered by the filter element 13.

[0031] As shown above, this embodiment is a sedimentation-type single-stage filter for filtering lubricating oil, comprising: a magnet 7 is provided at the sedimentation end of a sedimentation barrel 9, and the sedimentation barrel 9 is used to precipitate the lubricating oil, and the impurities in the sedimented lubricating oil are adsorbed by the magnet 7.

[0032] In the process of the lubricating oil flowing into the sedimentation barrel 9 and continuously rising, physical precipitation is achieved. At the same time, the magnet 7 at the bottom adsorbs the iron impurities in the lubricating oil, so that larger particles of impurities are first physically precipitated and then enter the filter element 13 for filtration, further improving the filtering capacity of the filter and increasing the service life of the filter element 13.

[0033] As shown above, in this embodiment, an inlet pressure gauge 2 and an outlet pressure gauge 16 are respectively provided on the inlet 3 of the outer barrel 4 and the outlet 15 of the filter element barrel 10, which are used to detect the pressure of the lubricating oil entering and being discharged.

A flushing valve 5 for controlling the flushing of the sedimentation barrel 9 and an oil drain valve 8 for removing debris are provided on the sedimentation barrel 9.

[0034] Pressure gauges are installed at both the filter inlet 3 and outlet 15. When the difference between the inlet pressure gauge 2 and the outlet pressure gauge 16 reaches a preset value, it indicates that there are too many impurities in the filter screen of the filter element 13. At this time, the oil drain valve 8 is opened to drain the lubricating oil inside the filter. After the lubricating oil is completely drained, the filter element 13 is replaced. Then, clean lubricating oil is introduced into the filter through the flushing valve 5 to flush the impurities deposited at the bottom of the filter. Finally, the lubricating oil containing impurities is discharged from the oil drain valve 8.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
