DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4A self-cleaning pipeline filter comprises a shell 1, a liquid inlet pipe 101 is plugged into one side of the top of the shell 1, a liquid outlet pipe 102 is plugged into one side of the bottom of the shell 1, an upper inclined mask 2 is integrally formed on the circumferential inner wall of the shell 1, a support cylinder 3 is plugged into the top of the upper inclined mask 2, two inner through ports 4 are arranged on the circumferential outer wall of the support cylinder 3, an upper filter screen 5 is clamped in the inner through ports 4, a pointed cone 6 is integrally formed on the top of the support cylinder 3, a lower inclined mask 7 is integrally formed on the circumferential inner wall of the shell 1, a lower filter screen 8 is clamped in the top of the lower inclined mask 7, liquid enters the support cylinder 3 through the filtration of the upper filter screen 5, and then the liquid falls on the lower filter screen 8, thereby filtering the liquid through the lower filter screen 8 The liquid is filtered again and finally discharged from the liquid outlet pipe 102. The top outer wall of the shell 1 is fixed with a motor 9 by bolts. The output end of the motor 9 is keyed to a connecting shaft 10. The outer wall of the connecting shaft 10 is fixed with two upper scrapers 11 and two lower scrapers 12 by bolts. The upper scraper 11 contacts the inner wall of the shell 1 and the upper filter screen 5, and the lower scraper 12 contacts the inner wall of the shell 1 and the lower filter screen 8. Driven by the motor 9, the connecting shaft 10 rotates, thereby driving the upper scraper 11 and the lower scraper 12 to rotate, and then scraping on the inner wall of the shell 1, the upper filter screen 5 and the lower filter screen 8, so as to remove impurities on the inner wall of the shell 1, the upper filter screen 5 and the lower filter screen 8.

[0022] The outer wall of the shell 1 is provided with two external openings 14, and the inner wall of one side of the external opening 14 is rotatably connected with a curved door 13, and the outer wall of one side of the curved door 13 is integrally formed with a clamping block 15. The outer wall of one side of the shell 1 is rotatably connected with two threaded rods 16, and the threaded rods 16 are clamped with the clamping block 15. A butterfly nut 17 is threadedly sleeved on one end of the threaded rod 16. Unscrew the butterfly nut 17 and pull the threaded rod 16 to separate from the clamping block 15, so as to facilitate opening the curved door 13. A sealing gasket 18 is bonded to the inner side of the curved door 13 to improve the sealing between the curved door 13 and the external opening 14.

[0023] The working principle of this embodiment is as follows: when in use, first, liquid is injected into the shell body 1 from the liquid inlet pipe 101, then, the liquid enters the support tube 3 through the filtration of the upper filter screen 5, then, the liquid falls on the lower filter screen 8, thereby filtering the liquid again through the lower filter screen 8, and finally, discharged from the liquid outlet pipe 102. When cleaning, the connecting shaft 10 is rotated under the drive of the motor 9, thereby driving the upper scraper 11 and the lower scraper 12 to rotate, and then scraping on the inner wall of the shell body 1, the upper filter screen 5 and the lower filter screen 8, thereby removing impurities on the inner wall of the shell body 1, the upper filter screen 5 and the lower filter screen 8, and then, unscrewing the butterfly nut 17, pulling the threaded rod 16 to separate from the block 15, so as to facilitate opening the curved door 13, and then facilitate the discharge of impurities.
