Abstract

Improvements in the construction of continuous automatic unclogging rotary filters for loaded liquids, consisting of a filter drum, permanently driven in rotation, one of whose two closing plates, joined together by separators, comprises a central inlet hole for said liquids. loaded, and whose cylindrical surface is constituted by a filtering screen, crossed from the inside to the outside by these liquids to be filtered and on whose internal face the impurities are deposited, said cylindrical surface being sprayed from the outside by a pressure liquid ramp, provided with appropriate jets, and located in a projection with respect to the upper ascending sector of the filter screen, substantially at the level of the bisector plane of a fixed hopper placed inside the filter drum, and destined for the recovery of the unclogging residues, dropping said residues inside the hopper by gravity and b The effect of the liquid pressure of the unclogging ramp is added, where they are collected by a coaxial Archimedean screw dragged in rotation and lodged in the lower part of the hopper, the bottom of which is shaped for this purpose, a filter characterized by the fact that the The axis of the Archimedean screw is joined to one of the drum plates by means of at least one radial arm that passes through said central entrance hole for the loaded liquid.
