Grease alkali refining device

The utility model relates to a grease alkali refining device is used for grease alkali refining field. Technical scheme below adopting: a grease alkali refining device comprises lye tank, water tank, alkali refining pot, centrifugal separator, oil tank and soap pan, and wherein lye tank and water tank insert the transfer line and communicate with the alkali refining pot after connecting in parallel through the water pipe high position of intaking, the alkali refining pot is linked together through the feed liquor end of nigre liquid conveyer pipe and centrifugal separator, inputs the centrifugal separator with nigre liquid, the centrifugal separator goes out the liquid end and divide into two way pipelines, and of the same kind and oil tank is linked together, and another way is linked together with the soap pan. The present grease alkali refining device of a grease alkali refining device have following advantage: have simple structure, easy operation can improve the alkali refining yield, has solved the handling problem of the nigre that produces behind the present grease alkali refining simultaneously.
