Abstract (en)

[origin: EP1043121A1] A deodorization system for a lens-grinding machine (1) for grinding a lens (4) has a suction hose (12, 14) and a deodorization device (36). Bad-smelling air in sucked from the grinding chamber (2) and a waste water tank (7) for storing waste water used in the chamber (2) through the tank (7). The bad-smelling air sucked through the suction hose (12, 14) is filtered by a dehydration filter (13), a centrifugal separator (23) and a fine filter (37) to separate and remove the waste water, bubbles and cut chips from the bad-smelling air, and is deodorized by the deodorization device (36). A water storage tank (24) arranged in the separator (23) stores the waste water, the bubbles and the cut chips removed from the bad-smelling air. A volume detection sensor (35) provides a signal upon the increase of the volume of the waste water stored in the tank (24) to a value substantially equal to the capacity of the tank (24) to prevent the overflow of the waste water from the tank (24). <IMAGE>
