【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明は例えばディーゼルエンジン用の潤滑油の清浄
化に用いることができる油清浄装置に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an oil cleaning device that can be used for cleaning a lubricating oil for a diesel engine, for example.
＜従来の技術＞ 遠心分離器を一部利用した従来の油清浄装置を第２図

である。<Prior Art> FIG. 2 shows a conventional oil cleaning apparatus partially using a centrifugal separator. This equipment first pumps the oil to be purified
Is sent to the centrifuge 2 to separate crude contaminants in the oil. Next, the oil from which the crude contaminants have been separated is filtered by the second pump 3 through the filter 4
The residual contaminants in the oil are separated by a filter medium.

ネルギーを必要とする。<Problems to be Solved by the Invention> However, in the above-mentioned conventional oil cleaning apparatus, since the centrifugal separator and the filter are separately installed, a large space is required and piping work between them is required. . It also requires another pump and its drive energy to deliver oil to the filter.

他、濾過器の濾材の目詰まり度の判定を濾過器の入口側

不正確であった。Further, in the conventional device, since the oil introduction pressure to the filter medium of the filter and the pressure from the filter inlet side by the pump 3 are used, when the filter medium becomes clogged from the filter inlet side, the pressure inside the filter medium rapidly increases. As a result, the amount of oil passing through the filter medium was reduced, and the service life of the filter medium was remarkably shortened. In addition, the degree of clogging of the filter material of the filter was determined by the pressure difference between the inlet side and the outlet side of the filter, but the variation was large and inaccurate.
＜目的＞ そこで本発明は上記従来技術の欠点を解消し、省スペ

清浄装置の提供を目的とする。<Purpose> Therefore, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, and to provide an oil cleaning device that saves space and energy, and has a long filter medium life.

する。<Means for Solving Problems> An oil cleaning apparatus according to the present invention is a centrifugal separator for centrifuging a crude contaminant in the sent oil, and residual contamination in the oil sent from the centrifugal separator. A filter that filters through the filter material of the object is integrally connected so as to rotate integrally around the same rotating shaft, and under centrifugal load conditions, oil continuously flows from the centrifugal separator through the filter. The basic characteristic is to be purified.

Since the filter is integrally connected to the centrifuge, the centrifugally separated oil is naturally transferred to the filter without using a pump or the like. Further, since the filter rotates together with the centrifugal separator, the filtration pressure is applied to the oil without applying the pump pressure or the like. Since the filtration pressure is due to the centrifugal force, the pressure on the outside (outlet side) of the filter medium increases, so that it is less likely to be destroyed and the filter medium life is extended.

て急激に濾過圧が低下することがない。The operation will be described. When the operation switch is turned on, the drive motor 11 rotates, the oil transfer pump 12 starts oil transfer, and the centrifugal separator 13 starts rotating integrally with the filter 20. The oil introduced from the vicinity of the bottom of the centrifuge 13 through the oil introduction pipe 18 is subjected to centrifugal separation of crude contaminants. The oil filled in the centrifuge 13 moves from the transfer port 17 to the filtration chamber 22, passes through the filter medium 23 under a centrifugal force, and the residual contaminants are filtered. The oil that has passed through the filter medium 23 is sent out to the oil transfer pipe 33 through the space 31 and the oil reservoir 32. During this period, the process from the introduction of the oil to the centrifugal separator 13 by the oil transfer pump 12 to the delivery of the filtered oil to the oil transfer pipe 33 is continuously performed. Since centrifugal force is applied during the filtration, the filtration capacity is large, and the filtration pressure does not drop sharply from the oil-filled side of the filter medium 23 to the extraction side.
