Abstract

본 발명은 폐수의 원심력을 이용하여 필터 입자물의 역세척을 위한 별도의 장치의 필요성을 제거하고, 또한 슬러지를 나사봉을 이용하여 효과적으로 배출할 수 있는 원심 모래 여과기에 관한 것이다. 여과 탱크에 유입된 폐수는 원심력에 의하여 여과 탱크 내의 필터층을 교반하여, 필터층 내의 슬러지는 여과 탱크 중앙에 위치된 필터 분출관에 형성된 나선을 따라서 상승되고, 폐수중의 일부는 필터층을 통하여 여과된다. 필터층의 표면 및 하부의 필터는 필터 분출관에 연결된 공기 공급부의 공기 공급으로 필터 분출관을 따라서 분출되는 과정에서 역세척된다.The present invention relates to a centrifugal sand filter capable of eliminating the need for a separate device for backwashing filter particle water using the centrifugal force of wastewater and effectively discharging the sludge by using a screw bar. The wastewater flowing into the filtration tank agitates the filter layer in the filtration tank by centrifugal force so that the sludge in the filter layer rises along the spiral formed in the filter discharge pipe located at the center of the filtration tank and a part of the wastewater is filtered through the filter layer. The filter on the surface and the bottom of the filter layer is backwashed in the process of being blown out along the filter discharge pipe by the air supply of the air supply unit connected to the filter discharge pipe.
