The monitoring component 67 is arranged inside the filter cartridge 1. The threaded rod 61 is driven by the rotating wheel 62 to make the threaded block 63 drive the inclined column 64 to rotate, so that the curved column 65 drives the insertion rod 66 to leave the filter element 5, and the filter element 5 is quickly disassembled and cleaned. The monitoring component 67 reminds the staff that the filter element 5 is blocked.

[0024] During the specific implementation process, it is worth noting that the hydraulic oil inside the hydraulic pipeline enters the interior of the filter cartridge 1 through the liquid inlet pipe 3. After being filtered by the filter element 5, the hydraulic oil is discharged from the filter cartridge 1 through the liquid outlet pipe 4 and re-enters the hydraulic pipeline to filter the hydraulic cylinder. When it is necessary to filter the filter element 5, the staff rotates the cylinder cover 2 and rotates the cylinder cover 2 down. The staff rotates the rotating wheels 62 on both sides in turn.

The staff rotates the rotating wheel 62 in the opposite direction in turn, so that the insertion rod 66 is reinserted into the filter element 5 and fixed. This allows the filter element 5 to be quickly disassembled and cleaned.

[0025] Furthermore, the monitoring component 67 includes: a liquid pressure sensor 671 model is selected according to actual needs and can meet the work requirements. The liquid pressure sensor 671 is fixedly connected to the inner wall of the filter cartridge 1 by bolts and extends to the inside of the filter cartridge 1. After completion, the staff rotates the bolts to fix the liquid pressure sensor 671 to the filter cartridge 1. The liquid pressure sensor 671 detects the liquid pressure inside the filter cartridge 1. When the liquid pressure inside the filter cartridge 1 exceeds a predetermined value, the liquid pressure sensor 671 transmits a signal to the external controller, and then transmits it to the external alarm through the sensor, so as to remind the staff that the filter element 5 is blocked and clean the filter element 5 in time. The positioning block 672 is fixedly connected to the outer wall of the liquid pressure sensor 671 and plugged into the filter The inner wall of the cylinder 1, at this time the liquid pressure sensor 671 drives the positioning block 672 to move, the positioning block 672 is inserted into the filter cylinder 1, the liquid pressure sensor 671 is positioned, the sealing ring 673 is installed on the inner wall of the filter cylinder 1, and fits the outer wall of the liquid pressure sensor 671.

The staff inserts the probe part of the liquid pressure sensor 671 into the filter cartridge 1 so that the outer wall of the probe of the liquid pressure sensor 671 fits together with the sealing ring 673 to seal it. At this time, the liquid pressure sensor 671 drives the positioning block 672 to move, and the positioning block 672 is inserted into the filter cartridge 1 to position the liquid pressure sensor 671. After completion, the staff rotates the bolt to fix the liquid pressure sensor 671 to the filter cartridge 1. The liquid pressure sensor 671 detects the liquid pressure inside the filter cartridge 1. When the liquid pressure inside the filter cartridge 1 exceeds a predetermined value, the liquid pressure sensor 671 transmits a signal to the external controller, and then transmits it to the external alarm through the sensor, so as to remind the staff that the filter element 5 is blocked and to clean the filter element 5 in time.

When the filter element 5 needs to be filtered, the staff rotates the cylinder cover 2 and rotates the cylinder cover 2 down. Then, the staff rotates the rotating wheels 62 on both sides in turn, and the rotating wheels 62 drive the threaded rod 61 to rotate, and the threaded rod 61 drives the threaded block 63 to move. The threaded block 63 moves on the sliding rod 631, and the threaded block 63 drives the inclined column 64 to rotate, and the inclined column 64 drives the curved column 65 to move, and the curved column 65 drives the plug rod 66 to move. The plug rod 66 moves in the empty box 7, and the plug rod 66 leaves the filter element 5.
