The present invention relates to a filtering apparatus using a reverse cleaning method. The purpose of the present invention is to increase filtering and cleaning efficiency as a filter function and a cleaning function of a filter are performed at the same time by forming a suction unit to impose suction pressure alternately on an upper end portion and a lower end portion of the filter. The filtering apparatus includes: a housing having an insertion pipe, formed on one side thereof, and a discharge pipe, formed on the other side; multiple filters arranged in the housing; a separation wall which supports the filter; the suction unit which includes a first suction pipe channel, located in the center of the housing, and a second suction pipe channel, which is extended from the first suction pipe channel to be located on one end portion of the filter and performs a reverse cleaning procedure with respect to the filter by suction pressure imposed on the first suction pipe channel; and a rotation unit which provides rotational force to the suction unit. The separation wall comprises a first separation wall (30) and a second separation wall (40) which support the upper end portion and the lower end portion of the filter (20). The second suction pipe channel (54) of the suction unit (50) is formed to alternately arrange the upper end portion and the lower end portion of the filter (20) so that filtration of fluid and cleaning of the filter (20) can be performed at the same time in one filter (20). |
