During the filtering process, the vibrator 18 drives the filter element 16 and even the entire slurry tank 10 to vibrate, increasing the slurry fluidity and improving the slurry filtration efficiency. Here, since the inclined dividing ring 8 divides the filter element mounting seat (the lower filter element mounting seat 7 and the upper filter element mounting seat 9) into two parts at an inclined surface, the slurry tank 10 and the filter element 16 are actually installed in On the inclined dividing ring 8, when the vibrator 18 vibrates, due to the effect of gravity, the bottom slurry actually flows in one direction, and the filtering effect is better. At the same time, the filter element lower cover 17 and the filter element upper cover 19 are both designed with stop rings to prevent loosening during vibration. The buffer mechanism on the top of the filter element upper cover 19 effectively increases the vibration space of the filter element 16. In addition, the timing control cylinder 3 drives the Teflon scraper mechanism 25 to move up and down to clean the sludge-like waste adhering to the filter element 16, and the filtered waste is discharged through the waste port 4.
