[0033] In this embodiment, by providing the guide plate 18, the filtered impurities and dirt can be guided and moved.

[0034] Working principle: The staff connects the liquid inlet pipe 11 and the liquid outlet pipe 12 with the pipeline of the external centralized lubrication system through the use of the flange 13 and the external screws. Then, when the centralized lubrication system is running, the oil enters the inner cavity of the positioning pipe 3 of the inner cavity of the filter cylinder 1 through the liquid inlet pipe 11. At the same time, the filter screen 4 filters the oil in the inner cavity of the positioning pipe 3, so that the impurities and dirt contained in the oil are filtered on the inner surface of the filter screen 4. At the same time, the filtered oil continues to flow back to the centralized lubrication system through the use of the filter cylinder 1 and the liquid outlet pipe 12, so that it circulates and lubricates. At the same time, when the oil enters the inner cavity of the filter cylinder 1, the oil conducts heat to the filter cylinder 1 and the heat dissipation fins 10, thereby increasing the heat dissipation area of ​​the oil and improving the heat dissipation effect of the oil.

[0035] When it is necessary to clean the impurities and dirt in the inner cavity of the filter cartridge 1, the staff energizes the electric cylinder 5 plug and starts the external controller of the electric cylinder 5, so that the telescopic end of the electric cylinder 5 drives the scraper 6 to move up and down, so that the scraper 6 scrapes and cleans the impurities and dirt attached to the inner surface of the filter screen 4. At the same time, the impurities and dirt after scraping and cleaning are settled into the inner cavity of the dirt storage barrel 8 through the sewage pipe 7, thereby realizing the scraping and collection of impurities and dirt. Then, the staff closes the sewage pipe 7 valve and closes the sewage pipe 7. Then, the staff rotates the movable barrel cover 9 to make the barrel cover 9 away from the dirt storage barrel 8, thereby opening the dirt storage barrel 8, making it convenient for the staff to clean the impurities and dirt without stopping the machine. The device is simple to operate and is convenient for non-stop filtering and cleaning, thereby meeting the customer's usage needs.
