Abstract

A kind of moving filter bed type filtering apparatus which comprises the filter bed at the bottom with granular filter whose density greater than one ; the overspill dam on the top of filter fluid chamber above the filter bed; the water supply portion connected to the water source so the water supplied by the supply portion flow through the filter bed and filtered out and drain from the overspill dam to the filter tank; and, there is an opening below the filter bed and connected to the supply source of compressed air on the underneath and center portion; exhaust the filter from the bottom of filter bed by compressed air and transmit to the air upflow; and infused in the filter fluid of filter fluid chamber; there is a separation room on top of the upper opening of the air upflow; and a dam plate in the separation room handling the overspill level; and the exhaust portion exhaust the cleaned water overspilled from the dam plate; connection portion below the filter chamber connected the separation room and filter fluid chamber; dredged portion allocated homocentrically with connection portion and connected to the separation room; the filter and contaminant separated from the filter from the top of the air upflow is exhausted from the overspill dam and transmit the cleaned filter to the cleansing tower upon the filter bed; and dredged tube round supply the filter to the water supply source.
