Abstract

Perfeccionamientos en aparatos de evacuación para la limpieza de depósitos de filtración caracterizándose porque tienen un canal que se extiende por toda la longitud del depósito y cuyo fondo está por debajo de la parte superior de la capa filtrante teniendo este canal una por lo menos de sus paredes laterales al nivel de la capa filtrante perforada con unos orificios que se cierran normalmente con unas válvulas móviles de compuerta que se mantienen apoyadas sobre sus asientos por el agua contenida en el citado canal estando abiertos estos orificios simultáneamente al final de la operación de lavado para permitir la evacuación de la capa de agua sucia por el descenso del nivel del agua contenida en el canal.Improvements in evacuation devices for cleaning filtration tanks, characterized in that they have a channel that extends over the entire length of the tank and whose bottom is below the upper part of the filter layer, this channel having at least one of its walls lateral at the level of the perforated filter layer with holes that are normally closed with mobile gate valves that are supported on their seats by the water contained in said channel, these holes being open simultaneously at the end of the washing operation to allow the evacuation of the dirty water layer due to the decrease in the level of the water contained in the channel.
