이때, 도 1에 도시된 것처럼, 감속 모터(40)의 동력이 여과드럼(10)과 브러시 수단(30)으로 전달되어, 여과드럼(10)과 브러시 수단(30)의 육각통(31)이 각각 회전하게 된다. At this time, as shown in Figure 1, the power of the reduction motor 40 is transmitted to the filter drum 10 and the brush means 30, the filter drum 10 and the hexagonal cylinder 31 of the brush means 30 is Each rotates.

이것에 의해, 도 4에 도시된 것처럼, 여과드럼(10)이 화살표(15) 방향으로 회전할 때, 브러시 수단(30)의 육각통(31)이 화살표(39) 방향으로 회전하게 됨으로써, 육각통(31)에서 방사상으로 돌출된 브러시 솔(36)이 여과드럼(10)의 외주면을 탁탁치면서 닦아내게 됨으로써, 여과드럼(10)에 천공된 여과공(11)이 막히는 것을 방지할 수 있게 된다. 더 나아가, 브러시 솔(36)이 마모될 경우, 평철(34)을 분리한 후, 브러시 솔(36)을 간편하게 교체할 수 있는 장점이 있다.As a result, as shown in FIG. 4, when the filter drum 10 rotates in the direction of the arrow 15, the hexagonal cylinder 31 of the brush means 30 rotates in the direction of the arrow 39, thereby making the hexagonal The brush brush 36 that protrudes radially from the barrel 31 is wiped off while tapping the outer circumferential surface of the filter drum 10, thereby preventing the filter hole 11 perforated in the filter drum 10 from being blocked. . Further, when the brush brush 36 is worn, after removing the flat iron 34, there is an advantage that the brush brush 36 can be easily replaced.
