Abstract

Sistema perfezionato di filtrazione di liquidi con particelle in sospensione, fra quelli che presentano un gruppo di valvole di distribuzione di liquido, un filtro ed un serbatoio di decantazione, nel quale le particelle in sospensione nel liquido possono sedimentare in differenti fasi con velocità decrescenti di sedimentazione, caratterizzato dal fatto che si prevedono dei mezzi per scaricare il serbatolo di decantazione attraverso la sua parte superiore, che controllano la riduzione del livello del liquido nel detto serbatoio, prima di iniziare il funzionamento dei detti mezzi attendendo che trascorra almeno una parte del tempo corrispondente alla fase di maggior velocità di sedimentazione. L'invenzione è applicabile nel campo della filtrazione dei liquidi contaminati da macchine utensili. (Figura 1).
