Multiple guide plates 14 are welded to the inner wall of the housing 2. One side of each guide plate 14 is welded to the outer circumferential wall of the filter cartridge 15. The filtered liquid flows between the guide plates 14 and then downwards through the gaps in the guide plates 14 into the oil outlet pipes 7, thereby increasing the usable area of ​​the filter cartridge 15 and improving the filtration effect. An oil inlet pipe 3 is welded to the bottom outer wall of the housing 2. A second connecting block 6 is welded to the outer circumferential wall of the oil inlet pipe 3. A sealing ring 11 is bonded to the bottom of the connecting block 6. A sealing groove 12 is formed on the top of the first connecting block 4, and the sealing groove 12 is inserted into the sealing ring 11. A connecting pipe 5 is welded to the bottom of the first connecting block 4.

A cross filter element 13 is slidably connected to the inner wall of the sliding groove 18. Rotating the nut 22 disengages it from the connecting rod 21. Then, rotating the L-shaped plate 19 to a certain angle disengages it from the fixing seat 16. Subsequently, the connecting plate 23 is disengaged from the outer circumference of the connecting rod 21. Then, the sealing cover 1 is opened, and the cross filter element 13 is removed from the sliding groove 18 and inserted. The sealing cover 1 is then closed, bringing the fixing seat 16 into contact with the U-shaped frame 17.The connecting plate 23 is fitted onto the connecting rod 21 and moved downwards until it contacts the upper surface of the U-shaped frame 17. Then, the nut 22 is fitted onto the connecting rod 21, and the nut 22 is rotated to the top of the connecting plate 23 to secure it.

Rotating the threaded rod 10 fixes the threaded rod 10 to the fixing block 8, which solves the problem of weak points at the pipe body, improves the safety and service life of the connection, and ensures the safety and reliability of the system operation.

[0024] Working principle: When it is necessary to filter the sucked-back oil, first turn the nut 22 to disengage it from the connecting rod 21. Then, turn the L-shaped plate 19 to a certain angle to disengage it from the fixed seat 16. Next, disengage the connecting plate 23 from the outer circumference of the connecting rod 21. Then, open the sealing cover 1, take out the cross filter element 13 from the slide groove 18, put the cross filter element 13 in, and cover the sealing cover 1. Make the fixed seat 16 contact the U-shaped frame 17. Put the connecting plate 23 on the connecting rod 21 and move it down until it contacts the upper surface of the U-shaped frame 17. Then, put the nut 22 on the connecting rod 21 and turn the nut 22 to the top of the connecting plate 23 to fix it. This completes the replacement of the cross filter element 13.
