Description

Technical Field

[0001] The invention relates to a high-speed centrifugal oil purification device. Background Art

[0002] The centrifugal oil purifier adopts the centrifugal separation principle to remove solid impurities, water, air and other pollutants in the oil. The centrifugal oil purifier rotates at high speed, causing the oil to generate a centrifugal force hundreds of times its own weight. By utilizing the principle that the specific gravity of substances is different, harmful substances such as solids, liquids, and gases in the oil are quickly separated from the oil under the action of centrifugal force. The solid impurity layer formed will form a layer of oil sludge, which accumulates on the inner surface of the rotating container. Although the existing centrifugal oil purifier can separate the oil and solid impurities by centrifugation, it is difficult to operate when collecting the oil and solid impurities separately, and secondary pollution often occurs. Summary of the invention
