Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention proposes an improvement of an oil purifier installed in the circulation path of a lubricating oil pipe in automobiles and various equipment.

[Conventional technology]

As an oil purifier, the one shown in FIG. 3 has been widely known. That is, in the figure, numeral 1 is a sealed envelope-shaped case, 2 is an oil supply pipe extending from the outside to the inner chamber A of the case 1, 3 is an oil supply pipe extending from the inner chamber A to the outside, and the oil supply pipe 3 has an outlet port. A filter element 5 is installed so as to surround the periphery of the filter element 4. A pump (not shown) causes oil flowing through the oil supply pipe 2 to flow in the interior chamber A in the direction of the arrow in the figure through a conical opening 6 formed at the end of the oil supply pipe 2, and into the filter element 5. Moisture, impurities, etc. are separated during the passage through the oil, and the purified oil is sent from the outlet 4 through the oil feed pipe 3 to external equipment. On the other hand, the water and impurities filtered and separated by the filter element 5 settle into the drain reservoir 7 at the bottom of the inner chamber A,
It is periodically discharged by the drain discharge device 8.

[Problem that the invention attempts to solve]

However, according to the above-mentioned conventional configuration, the flow of oil and the precipitation of filtered and separated moisture and impurities are carried out in the interior chamber A of the case 1, and when the equipment is operated, the above-mentioned precipitation occurs. Since the flow of oil in the inner chamber A acts to prevent precipitation, there are problems such as poor filtration efficiency of the filter element 5 and easy clogging. Complete precipitation in the drain reservoir 7 had to wait until after the equipment was stopped.

[Means for solving problems]

The oil purifier according to the present invention solves the above problems and aims to improve the filtration efficiency and extend the life of the filter element. A cylindrical body surrounding a space is provided, a flange portion of the cylindrical body is attached to the inner circumferential surface of the case, and the oil supply pipe is introduced into a portion near the flange portion in the outer circumferential space of the cylindrical body. This is what I did.

[Function] According to the oil purifier configured as described above, oil flowing through the oil supply pipe first flows from the outer circumferential space formed by partitioning the inner chamber of the case by the cylindrical body, and then flows into the cylindrical body. The oil enters the cylindrical space between the periphery of the oil pipe and the outer periphery of the filter element, passes through the filter element surrounding the vicinity of the outlet of the oil pipe, and is filtered and cleaned. Sent to external equipment. That is, the flow path of oil from the oil supply pipe toward the filter element and the outlet of the oil supply pipe in the case interior is limited to the outer peripheral space of the cylindrical body and the periphery of the filter element. It does not act to interfere with the precipitation of moisture, impurities, etc. filtered and separated by the filter element.

〔Example〕

Next, one embodiment of the oil purifier of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal cross-sectional view of this embodiment, and FIG. 2 is a cross-sectional view taken along the - line in FIG. 3 is an oil pipe that communicates from the inside of the case 1 to external equipment (not shown); 5 is a filter element installed to surround the outlet 4 of the oil pipe 3; 9 is a filter element; A cylindrical partition plate that surrounds the element with a cylindrical space in between and partitions the interior of the case 1 into an oil tank B on the outer circumferential side and a sedimentation tank C on the inner circumferential side. A flange 10 that expands in the outer diameter direction is formed at the side end of the flange 1 .
0 is attached to the inner peripheral surface of the case 1. Further, an end portion 2'a of the oil supply pipe 2' is introduced into the oil tank B.

The present embodiment is constructed as described above, and therefore oil flowing into the case 1 through the oil supply pipe 2' is pumped by an external pump (not shown) from the end 2'a of the oil supply pipe 2'. As shown by the arrow in the figure, the oil flows from the oil tank B on the outer peripheral side of the partition plate 9 to the space between the partition plate 9 and the filter element 5,
The oil is filtered by a filter element 5 installed so as to cover the outlet 4 of the oil pipe 3. Moisture, impurities, etc. separated by the filter element 5 sink in the sedimentation tank C in the inner peripheral space of the partition plate 9, settle in the drain reservoir 7 at the lower end of the interior of the case 1, and are discharged from the drain discharge device. 8, it is discharged regularly. That is, the partition plate 9 has the function of limiting the flow path of oil from the oil supply pipe 2' to the oil passage tank B on the outer peripheral side thereof and the vicinity of the filter element 5, and prevents the impurities etc. in the settling tank C. No flow occurs that would interfere with settling.

[Effect of idea]

As explained above, the oil purifier of the present invention has a cylindrical body inside the case so as to partition the interior of the case into an oil tank and a sedimentation tank, and an oil supply pipe is introduced into the oil tank. Since the flow path of oil from the oil supply pipe to the filter element and the outlet of the oil delivery pipe is limited to the inside of the oil passage tank and the vicinity of the filter element, there are There is no flow of oil that would prevent the precipitation of water and impurities filtered and separated by the filter element, and even when the equipment is in continuous operation, precipitation occurs in the same way as when it is stopped, thus reducing the filtration efficiency of the filter element. has improved significantly,
In addition, since clogging is suppressed, the service life is extended.
