Description

  The present invention relates to an oil-in-oil / foreign substance removing apparatus and a method for removing oil-in-oil / foreign substance in a lubricating oil.

  Conventionally, lubricating oil has been used in hydraulic control devices, pumps, engines, pistons, bearings, valves and the like. The lubricating oil contained in these products is circulated and reused, but by circulating the lubricating oil over a long period of time, solids such as metal powder mixed in the lubricating oil when used, Water used for cooling is mixed and accumulated. Prevent the progress of equipment wear, lubricating oil circulation failure, deterioration of lubricating oil performance, lubricating oil deterioration, corrosion of equipment, etc., and maintain the quality and purity of the lubricating oil contained in these products. Is important in maintaining the durability of the equipment.

  In order to maintain the quality and purity of the lubricating oil, conventional methods for removing the solid matter mixed in the lubricating oil include, for example, a stationary method and a filtration method. In addition, as a method of removing moisture mixed in the lubricating oil, for example, a stationary method using a specific gravity difference between oil and moisture, a centrifugal separation method, a superheating method, a voltage application method, a method of absorbing in a water absorbing material, and an adsorbing material There are filtration methods.

  Further, as a method of removing solids in the lubricating oil and removing moisture in the oil, for example, the lubricating oil containing solids and moisture is separated into oil and water using a centrifugal separation process, an oil / water separation tank or a gravity settling tank. There is a method of removing a part of solids and moisture by performing treatment with a hydrophobic hollow fiber membrane element after removing a part of solids and moisture by performing the treatment. Large solids such as metal scrap are separated by centrifugal separation, oil / water separation tank or oil / water separation process using gravity sedimentation tank, and small solids such as metal powder are hydrophobic hollow fiber membranes. While separating by the element, the emulsified water is separated by the hydrophobic hollow fiber membrane element to remove the water (see, for example, Patent Document 1).

  FIG. 15 shows an example of a separation device that uses a specific gravity difference between conventional oil and water. As shown in FIG. 15, the conventional water separation apparatus 100 supplies oil 103 containing water 102 into the apparatus main body 101, and the water 102 is supplied to the apparatus main body by utilizing the specific gravity difference between the oil 103 and the water 102. The oil settles at the bottom in 101 and is separated from oil 103. The oil 103 staying on the upper side of the apparatus main body 101 is extracted from the apparatus main body 101 and reused. Further, the oil 103 and water 102 staying on the bottom side of the apparatus main body 101 are extracted from the bottom side of the apparatus main body 101, supplied to the centrifuge 104, and separated into the oil 103 and water 102. 103 is reused and water 102 is discharged. Thus, the water 102 in the oil 103 is removed and the oil 103 is reused.

  However, in the conventional water separator 100, since it isolate | separates for every oil 103 stored by the apparatus main body 101, there exists a problem that separation of the oil 103 and the water 102 takes time. Moreover, since it is necessary to install the apparatus main body 101, there exists a problem that cost and expense start. In addition, when water 102 is mixed and emulsified in oil 103, it is necessary to separate all oil 103 into water 102 and oil 103 with a centrifuge 104, and to the oil 103 attached to the device. There is a problem that it is necessary to flush the resulting oil.

  Therefore, a method for continuously separating the water 102 in the oil 103 has been studied. FIG. 16 shows another example of a conventional water separator for separating oil and water. As shown in FIG. 16, the conventional water separation device 110 has a branch pipe 112 branched from a pipe 111 to which oil 103 is supplied, and filters 113 and 114 are provided in the pipe 111 and the branch pipe 112, respectively. . In the conventional water separator 110, when the filter 113 provided in the pipe 111 is replaced, the oil 103 flowing in the pipe 111 is supplied to the branch pipe 112, and the oil 103 is supplied by the filter 114 provided in the branch pipe 112. The water 102 inside is removed.

Since it can be adjusted, the adsorbent 13 can be supplied into the pipe 12 by an appropriate amount according to the measured moisture and foreign matter content in the lubricating oil 11. Further, the lubricating oil 11 may not contain moisture or foreign matter. Even in such a case, the adsorbent 13 is lubricated only when necessary by measuring the amount of moisture and foreign matter in the lubricating oil 11 in advance. The oil 11 can be supplied.

  Further, the flow rate of the lubricating oil 11 at this time depends on the viscosity and properties of the lubricating oil 11, but the flow rate of the lubricating oil 11 is, for example, 0.5 m / sec in order to accurately measure the moisture and foreign matter of the lubricating oil 11.
