A self-locking spring 15 is fixedly connected to the center of the other side of the sliding block 13. A pull rod 16 is fixedly connected to the side of the other side of the sliding block 13. In order to ensure the installation stability of the filter basket 10 and facilitate its removal and replacement, the self-locking mechanism 6 is provided.

[0025] Refer to Figure 2 , the side of the cleaning rod 8 is arc-shaped, and one side of the cleaning rod 8 is attached to the inner surface of the filter basket 10. The driving motor 5 is started, so that the rotating shaft 7 drives the cleaning rod 8 to rotate, and the impurities adhered to the inner surface of the filter basket 10 are cleaned.

[0026] Refer to Figure 2 , the bottom end of the rotating shaft 7 is movably connected to the clamping ring 9. The clamping ring 9 is clamped with the center of the bottom of the filter basket 10, so that the clamping ring 9 is clamped with the bottom of the filter basket 10 to limit and support the bottom end of the rotating shaft 7 and ensure the rotation stability of the rotating shaft 7.

[0027] Refer to Figure 3 , one side of the filter basket 10 is inclined, and both sides of the filter basket 10 are respectively adapted to the inner ends of the connection pipes 2. The medium flows into the interior of the cylinder 1 through one end of the connection pipe 2, enters the interior of the filter basket 10 through the lower side of the filter basket 10 for impurity filtration, and then exits from the other end of the connection pipe 2 through the upper side of the filter basket 10 to complete the medium filtration work.

[0028] Refer to Figure 3 , the top of the clamping block 11 is inclined, and the clamping block 11 is clamped to one side of the top surface of the flange cover 3.

Then, it is discharged from the other end of the connecting pipe 2 through the upper side of the filter basket 10 to complete the medium filtration work. During the filtration process, the driving motor 5 is started, so that the rotating shaft 7 drives the cleaning rod 8 to rotate, and the impurities adhered to the inner surface of the filter basket 10 are cleaned. The bottom end of the rotating shaft 7 is limited and supported by the clamping ring 9 to ensure the rotational stability of the rotating shaft 7. When the filter element needs to be replaced, first remove the flange cover 3, and remove the filter basket 10 from the interior of the cylinder body 1. Then, pull the pull rod 16 outward to separate the self-locking block 14 from the self-locking groove 12, and then pull the filter basket 10 downward to separate the clamping block 11 from the flange cover 3, and the removal work of the filter basket 10 can be completed. Then, the new filter basket 10 is clamped to the inner side of the cylinder body 1, and then the flange cover 3 is reinstalled to clamp the clamping ring 9 to the filter basket 10. At the same time, the clamping block 11 enters the interior of the flange cover 3, squeezing the self-locking block 14 to slide to one side. The movement of the self-locking block 14 drives the sliding block 13 to compress the self-locking spring 15 until the self-locking groove 12 on one side of the clamping block 11 and the self-locking block 14 move to the same horizontal height. Under the action of the self-locking spring 15, the self-locking block 14 resets and is clamped with the self-locking groove 12 to complete the self-locking fixation work of the filter basket 10 and complete the replacement work of the filter element.
