Lens grinding apparatus and apparatus for treating grinding water for use therein |
(57) A grinding water treating apparatus for use in a lens grinding apparatus is provided
which permits both grinding water treating means and deodorizing means to be accommodated
in a limited receptacle space, thereby permitting reduction of the receptacle space.
In a grinding water treating apparatus (27) for use in a lens grinding apparatus,
comprising a grinding water treating means (27a) which filters grinding water after
use in a glasses lens grinding work to separate grinding wastes and produce purified
water and a deodorizing means (51) for removing an offensive smell developed within
the grinding water treating means (27a) and also within a grinding water storage vessel
(3), both grinding water treating means (27a) and deodorizing means (51) are disposed
within the same housing (40).
Moreover, a lens grinding apparatus is provided having a grinding water storage vessel
(3) for the storage of grinding water which has been used in grinding a glasses lens
and a grinding water supply hose (19) which permits said grinding water to flow into
said grinding water storage vessel,
wherein, an injection means (N) is attached to a tip (19a) of said grinding water
supply hose, and said grinding water is injected radially by said injection means
to cover the surface of grinding water already stored in said grinding water storage
vessel, thereby extinguishing foams produced on the surface of said grinding water.
