Abstract:
1. A grinding water treating apparatus for separating processing refuse of an eyeglass lens from grinding water used for processing a periphery of the eyeglass lens, the grinding water containing the processing refuse being introduced from an eyeglass lens processing apparatus, the grinding water treating apparatus comprising: a lens grinding chamber having a drain pipe for the grinding water containing the processing refuse; a centrifugal separator that includes a dewatering tank having a bottom surface and a side surface and a drive source for rotating the dewatering tank, and springs out the grinding water through an upper portion of the dewatering tank by rotating the dewatering tank; and wherein the drain pipe introduces the grinding water containing the processing refuse from the grinding chamber into the dewatering tank, the centrifugal separator includes a ring-like shaped filter covering the upper portion of the dewatering tank and having an opening inserted with the drain pipe, for filtering the grinding water separated from the processing refuse by collecting the processing refuse at a lower portion of the filter and springing out the grinding water to an upper portion of the filter by rotating the dewatering tank.
