The No. 1 synchronous wheel 44 rotates through the No. 1 synchronous belt 441 to drive the No. 2 synchronous wheel 442 to rotate. The rotation of the No. 2 synchronous wheel 442 drives the No. 3 reciprocating threaded rod 52 to rotate.The third reciprocating threaded rod 52 rotates to drive the scraper 521 to move back and forth. The scraper 521 moves back and forth to drop the impurities attached to the filter plate 511 into the waste box 531. Finally, the filtered water can also be reused.
