Abstract

Disclosed is a method to recover viscous fluid (such as an encapsulant) at the bottom of used syringes or fluid dispensers and simultaneously fill new syringes with that recovered fluid. A deaeration process during the filling operation removes air bubbles trapped in the viscous fluid. Compressed air is used to force the fluid from one syringe to the other. The syringe to be filled is under vacuum. The system could also be used for any filling operation where the fluid has to be void of air bubbles.

Vacuum Transfer System for Chemicals Recovery and Filling

      Disclosed is a method to recover viscous fluid (such as an
encapsulant) at the bottom of used syringes or fluid dispensers and
simultaneously fill new syringes with that recovered fluid.  A
deaeration process during the filling operation removes air bubbles
trapped in the  viscous fluid.  Compressed air is used to force the
fluid from one syringe to the other.  The syringe to be filled is
under vacuum.  The system could also be used for any filling
operation where the fluid has  to be void of air bubbles.

      The system consists of a vacuum chamber which is a hermetically
sealed cylinder for receiving the two syringes.  On the top cover,
there is an adapter to receive the used syringe.  On the bottom side,
there is  another adapter for the new syringe.  A vacuum line is
connected to the  chamber so the new syringe and the chamber is under
vacuum.  A compressed  air line is connected to the top of the used
syringe.  When compressed  air is applied, the fluid is forced to the
new syringe, with the vacuum  removing any air bubbles trapped in it.
