Abstract
A grinding water treatment device for eyeglasses lens processing includes a centrifugal separator, a scraping unit, an opening, and a filter. The centrifugal separator includes a dehydration tank into which grinding water used in a processing device of an eyeglasses lens is introduced, and separates the grinding water into water and processing chips by rotation of the dehydration tank. The scraping unit scrapes out the processing chips accumulated on a side wall inside the dehydration tank. The opening is provided in the dehydration tank and through which the processing chips scraped out by the scraping unit are ejected to an outside of the dehydration tank. The filter is provided in an outer region of the opening, and through which the water separated from the grinding water by rotation of the dehydration tank passes to allow the processing chips to be present inside the dehydration tank.
