To provide an apparatus for recycling a waste oil by removing fine impurities, metallic powder, etc. contained in machining liquids used in machining sites, engine oils used in vehicles, etc., and, optionally, circulating recycled machining oil to the machine tool side, and to provide a waste oil recycling method using the apparatus.
The waste oil recycling apparatus comprises a waste oil container, a high-electric field-side electrode 1 and a contaminant-accumulating-side electrode 2, and a power source 3 for generating high electric field between both of the above electrodes. This apparatus works as follows: High electric field is generated between the above electrodes to accumulate contaminants in the waste oil on the contaminant-accumulating-side electrode. Using this apparatus, contaminants in waste oil are accumulated on the surface of the electrode 2 by generating high electric field in the waste oil, enabling the waste oil to be nearly completely recycled to its original state. The waste oil recycling method is applicable to all kinds of industrial oil including edible oil, engine oil and machine tool machining oil.
