A threaded ring 13 is fixedly installed on the left side of the filter plate 12 at the bottom end of the shell 1, and a sewage storage tank 4 is threadedly sleeved on the outer side of the threaded ring 13. A scraper 10 is provided on the left side of the filter plate 12 in the shell 1, and a sleeve rod 9 is fixedly installed on the top of the scraper 10. A limit frame 7 is fixedly installed on the top of the shell 1, and a threaded rod 8 is rotatably connected to the limit frame 7. The sleeve rod 9 is sleeved on the outer side of the threaded rod 8.

[0023] The top of the limit frame 7 is fixedly installed with a first motor 11, and the output end of the first motor 11 is fixedly installed on the threaded rod 8. The rotation of the threaded rod 8 by the first motor 11 is conducive to the use of this equipment. The top of the sleeve rod 9 is fixedly installed with a limit plate 6, which is sleeved on the outside of the threaded rod 8. The sleeve rod 9 can be limited by the limit plate 6. The left side of the shell 1 is fixedly installed with a liquid inlet pipe 2, and the bottom end of the shell 1 is located on the right side of the sewage storage tank 4. The liquid outlet pipe 3 is fixedly installed on the right side of the liquid inlet pipe 2 and the liquid outlet pipe 3 to facilitate the entry and exit of the lubricating oil. The top of the shell 1 is located on the right side of the limit frame 7 and is fixedly installed with a PLC The controller 5 is convenient for controlling the operation of the device through the PLC controller 5. The top ends of the two gear rods 22 are fixedly installed with L-shaped parts 14, and the front and rear ends of the shell 1 are fixedly installed with mounting brackets 19. The two L-shaped parts 14 are respectively slidably connected in the corresponding mounting brackets 19. The gear rods 22 can be limited by the L-shaped parts 14. The rear end of the shell 1 is located on the outside of the gear 21 and is sleeved with a bracket 24. The rear end of the bracket 24 is fixedly installed with a second motor 23. The output end of the second motor 23 is fixedly installed on the gear 21. The rotation of the gear 21 by the second motor 23 is beneficial to the use of the device.

[0024] Working principle: When in use, the lubricating oil enters the housing 1 through the liquid inlet pipe 2, filters the impurities through the filter plate 12, and then flows out through the liquid outlet pipe 3 to filter the impurities in the lubricating oil. The PLC controller 5 will regularly start the second motor 23 to work. The second motor 23 drives the gear 21 to rotate, so that the two gear rods 22 slide to the left. The two gear rods 22 drive the connecting plate 16 and the push rod 15 to retract into the housing 1, so that the push plate 17 slides to the left, and multiple ejectors 18 are inserted into the mesh on the filter plate 12 to squeeze out the impurities. Then the first motor 11 works to drive the threaded rod 8 to rotate. Since the sleeve rod 9 is provided with a thread corresponding to the threaded rod 8, the scraper 10 slides from top to bottom on the left side of the filter plate 12, which can scrape the extruded impurities and push them into the sewage storage tank 4, so that a single filter plate 12 is blocked. Then the first motor 11 and the second motor 23 reverses and drives the scraper 10 and the push plate 17 to reset. When it is necessary to clean the impurities in the sewage storage tank 4, the above principle can be used to make the scraper 10 drop to the bottom end of the shell 1. At this time, a seal can be formed on the top of the threaded ring 13. The staff rotates the sewage storage tank 4 to separate the sewage storage tank 4 from the threaded ring 13. Then the spare sewage storage tank 4 can be quickly threaded onto the threaded ring 13. Then the first motor 11 is used to drive the scraper 10 to reset, and the impurities in the sewage storage tank 4 can be cleaned without affecting the filtering work. This filter with anti-blocking function is easy to use. Through the above components, impurities on the filter plate 12 can be automatically cleaned regularly to avoid impurities clogging the mesh and affecting the normal filtering use of the lubricating oil. At the same time, impurities in the sewage storage tank 4 can be cleaned without stopping the lubricating oil filtration work, so as to avoid affecting the working efficiency of the lubricating oil filtration.
