Description

Technical Field

[0001] The utility model relates to a waste oil recovery device, in particular to a waste oil filtering device. Background Art

[0002] During the use of lubricating oil, due to the oxidation effect of high temperature and air, it will gradually age and deteriorate. Metal powders ground off by friction parts, moisture and impurities entering the oil from the outside will also catalyze the oxidation of the oil. Therefore, the color of the lubricating oil gradually darkens, the acid value rises during use, and precipitates, sludge, and paint films will be produced. These substances deposited on the surfaces of friction parts, the channels through which the lubricating oil flows, and the filters will cause various faults of the machine. Therefore, after a certain period of use, new oil needs to be replaced or the lubricating oil needs to be filtered. Most traditional filtering devices are for primary filtration and cannot completely filter out fine impurities in the lubricating oil. Content of the Utility Model

[0003] The purpose of the utility model is to provide a waste oil filtering device that can clean fine impurities in waste oil.

[0004] To achieve the above purpose, the technical solution of the utility model is:

The motor drives the filtering steel pot sleeved on the rotating column to rotate at a high speed through the pulley group, the rotating shaft, and the rotating column. The filtering steel pot rotating at a high speed uses centrifugal force to throw the fine impurities in the waste oil placed therein onto the wall of the filtering steel pot, filtering out clean lubricating oil. At the same time, the clean lubricating oil is transmitted back to the equipment through the oil outlet pipe, achieving the purpose of cleaning the fine impurities in the waste oil.
