Abstract
The invention discloses a novel suspension filter and a filtering system comprising the same. By arranging a movable partition and a filter screen, a housing is divided in order into an upper clear water region, a middle filtering region and a lower dirt-collecting region. Under the action of the inlet water pressure at the lower end of the housing and the action of buoyancy of suspending filtering media, the movable partition suspends at the top end of the housing, and the filtration effect is achieved by the multi-layer suspending filtering media. The filtered water enters the upper clear water region through the filter screen which is arranged in the center of the movable partition. During back-flushing, the pressure of the upper clear water region is higher than that of the middle filtering region, and the movable partition gradually moves down, so that the upper clear water region is enlarged and the middle filtering region is compressed to the minimum extent, the clear water enters the middle filtering region through a water distributor, undergoes vortex agitation and flushes the suspending filtering media, thus achieving the back-flushing effect. The system of a conventional settlement-type filter is simplified, a back-flushing water pump or air pump required for a back-flushing system is omitted, and the consumption of back-flushing water is greatly reduced. The novel suspension filter is simple, practical and free of extra energy consumption.
