摘要

An improvement in the devices for extracting sediments from the bottom of liquids, essentially characterized by the fact that it consists in establishing, in relation to the extractor tube of the apparatus, an auxiliary or several conduit, which conducts liquid to one or several zones adjacent to the mouth of said extractor tube in order to proceed to a slight removal of the particles of the sedimented material to be extracted maintaining at all times between them the pore space necessary for the passage of the liquid that has to drag them into the extractor tube, even when the mouth of this one is covered by the mass of sediment.
