Abstract

Il procedimento per incrementare il rendimento degli aspiratori a filtro liquido, consiste nel provvedere almeno due barriere addizionali di filtrazione mediante le quali l'ambiente liquido (10-11) e l'ambiente (01) aeriforme vengono materialmente separati da almeno un'interfaccia (5), avente una superficie sospesa sopra il liquido e coprente una parte preponderante della superficie superiore di esso. Essa esercita una leggera pressione sul pelo (11') libero del liquido (11), tale da limitare l'ebollizione da tale superficie coperta e obbliga le bolle di aria a seguire un percorso molto più lungo e quindi a frazionarsi. Detta interfaccia (5) rappresenta la base di un recipiente (5'), che si eleva ad incontrare un coperchio (6) a comignolo rovescio. La corrente d'aria di ebollizione ascende all'esterno della colonna (50), e giunta all'apice, viene costretta, dopo un percorso centripeto tortuoso, a passare, attraverso un filtro (8) fatto di materiale imputrescibile.The procedure for increasing the efficiency of the liquid filter vacuum cleaners consists in providing at least two additional filtration barriers by means of which the liquid environment (10-11) and the aeriform environment (01) are physically separated by at least one interface ( 5), having a surface suspended above the liquid and covering a preponderant part of the upper surface thereof. It exerts a slight pressure on the hair (11 ') free of the liquid (11), such as to limit the boiling from this covered surface and forces the air bubbles to follow a much longer path and therefore to split. Said interface (5) represents the base of a container (5 '), which rises to meet an inverted chimney cap (6). The boiling air stream ascends outside the column (50), and having reached the apex, is forced, after a tortuous centripetal path, to pass through a filter (8) made of rot-proof material.
