[0024] The asphalt enters the space on one side surrounded by the shell 10, the upper sealing ring 27, the lower sealing ring 28, the two sealing vertical strips 29 and the filter cartridge 13 through the feed pipe 11, and enters the filter cartridge 13 through the feed port 21. After being filtered through the filter hole 22, it enters the space on the other side surrounded by the shell 10, the upper sealing ring 27, the lower sealing ring 28, the two sealing vertical strips 29 and the filter cartridge 13, and is finally discharged from the discharge pipe 12, thereby filtering the impurities in the asphalt.

[0025] The upper sealing ring 27, lower sealing ring 28, and two sealing strips 29 enclose the circumference of the filter cartridge 13 to form two zones. The feed port 21 is located in one zone, which contains unfiltered asphalt, while the filter holes 22 are located in the other zone, which contains filtered asphalt. The inner sides of the upper sealing ring 27, lower sealing ring 28, and two sealing strips 29 are fixed to the outer wall of the filter cartridge 13, while the outer sides are sealed and engaged with the inner wall of the housing 10.

[0026] Preferably, a threaded hole 30 is provided on the bottom box 25 , and an external thread 31 is correspondingly provided on the bottom of the rotating shaft 23 .

[0027] Preferably, a plurality of vertical holes 32 are provided at intervals along the circumference of the bottom of the filter cartridge 13 , and vertical rods 33 are provided in the bottom box 25 to slide in correspondence with the vertical holes 32 .

[0028] The vertical rod 33 can slide over a distance greater than the height of the side wall of the bottom box 25 , so that the bottom box 25 can slide downward along the filter cartridge 13 to facilitate the discharge of debris collected in the bottom box 25 .

[0029] Preferably, the side wall of the bottom box 25 can be sealed and slidably connected to the outer surface of the filter cartridge 13.

[0032] Observation panel 34 is a heat-resistant glass window, allowing easy viewing and determining whether filter cartridge 13 requires cleaning. Motor 35 is also equipped with a corresponding power supply and control module to facilitate start and stop control. Of course, a knob or other drive method could be used in place of motor 35 to rotate shaft 23.

[0033] The working principle of this utility model is as follows:

[0034] The asphalt enters the space on one side surrounded by the shell 10, the upper sealing ring 27, the lower sealing ring 28, the two sealing vertical bars 29 and the filter cartridge 13 through the feed pipe 11, and enters the filter cartridge 13 through the feed port 21. After being filtered through the filter hole 22, it enters the space on the other side surrounded by the shell 10, the upper sealing ring 27, the lower sealing ring 28, the two sealing vertical bars 29 and the filter cartridge 13, and is finally discharged from the discharge pipe 12, thereby filtering the impurities in the asphalt; when the filter cartridge 13 needs to be cleaned, the output shaft of the motor 35 drives the rotating shaft 23 to rotate, and drives the spiral scraper 24 to rotate to scrape the impurities attached to the inner wall of the filter cartridge 13 downward into the bottom box 25 for collection. At the same time, under the action of the external thread 31 and the threaded hole 30, the rotating shaft 23 rotates to make the bottom box 25 slide downward and extend along the filter cartridge 13, so as to facilitate the discharge of the impurities collected in the bottom box 25, thereby improving the cleaning effect of the filter cartridge 13 and being easy to use.
