Abstract

Cet appareil de récupération de liquides comprend un premier et un second récipient de retenue (110, 112), une pompe à vide (156) conçue pour faire le vide de façon sélective dans l'un ou l'autre des récipients, ainsi que des moyens de commande (140) conçus pour déplacer le vide d'un récipient à l'autre lorsque le niveau de liquide dans l'un des récipients atteint un niveau maximum, le liquide contenu dans ce récipient en étant évacué tandis que le liquide continue d'être collecté dans l'autre récipient. Cet appareil fonctionne d'une manière cyclique afin de récupérer en continu du liquide en alternance dans les récipients. Le niveau de liquide est contrôlé par des soupapes à flotteur (134, 136) situées dans la partie la plus haute des récipients. L'évacuation du liquide est facilitée par la mise sous pression du récipient après que le liquide ait atteint le niveau le plus élevé, cette pression étant enlevée lorsque le liquide tombe au niveau le plus bas, lequel est détecté par des détecteurs de niveau (176, 178) situés dans la partie la plus basse des récipients. On fait fonctionner et on commande cet appareil avec de l'air comprimé, et on utilise une pompe à vide du type venturi.
