Description

Oil Separation Device {THE OIL SKIMMER}

The present invention relates to an oil separation device, and more particularly, to an oil separation device having improved performance of removing waste oil and the like from cutting oil and recovering purified cutting oil.

When machining metal, etc., heat due to friction is generated between the cutting tool and the workpiece, and the cutting tool and the workpiece are thermally deformed, thereby reducing the lifespan. In addition, the surface between the cutting tool and the workpiece is roughened, resulting in poor machining quality. For this reason, cutting oil is used when processing metal, etc. Coolant is used as a coolant during machining, and it increases the life of the cutting tool by softening the surface of the cutting tool.

These cutting oils contain components harmful to the human body, such as arsenic, cadmium, lead, and hexavalent chromium. In addition, it contains chemical components such as chlorine, chemical paraffin, naphthalene soap, polyoxyethylene derivative, rust inhibitor, and phosphate. Therefore, workers engaged in metal processing are exposed to diseases such as asthma, hypersensitivity pneumonia, and dermatitis due to contact with cutting oil or inhaling oil mist. Therefore, the management of cutting oil is important.

In addition, since the cutting oil is manufactured by mixing an industrial emulsifier and water in a certain ratio, the oil component decomposes and becomes waste oil. Such waste oil has a problem of reducing the life of the cutting oil by separating the cutting oil or accelerating the decay of the cutting oil. Therefore, it is important to remove the spoiled waste oil and the like.

1 is a view schematically showing an oil separation device 1 according to an embodiment of the present invention.

Referring to FIG. 1 , the oil separation device 1 according to the present invention recovers the purified cutting oil by removing waste oil and foreign substances from cutting oil used for material processing. The oil separation device 1 according to the present invention includes a receiver 10 , a separation plate 20 , a discharge unit 30 , and a recovery unit 40 .

The receptor 10 includes a bottom portion 100 and a side wall portion 110 to define an interior space. The bottom part 100 may be disposed parallel to the ground. The side wall part 110 is disposed at the edge of the bottom part 100 . The side wall part 110 may be disposed perpendicular to the bottom part 100 . The separation plate 20 extends from the first side to the second side of the side wall part 110 to separate the inner space. The discharge part 30 is connected to the receiver 10, and discharges the waste oil among the cutting oil. The recovery unit 40 is spaced apart from the discharge unit 30 and connected to the receiver 10 . The recovery unit 40 recovers the purified cutting oil. The recovered cutting oil is reused for metal (material) processing.

The separator 20 is spaced upward from the bottom 100 to define a slit S between the separator 20 and the bottom 100 . The separation plate 20 may be spaced apart from the bottom part 100 by a first height. Decayed waste oil floats on the cutting oil. That is, the decayed waste oil is floated, and the purified cutting oil is located under the waste oil. Therefore, the purified cutting oil is moved through the slit (S) of the separator (20). Corrupted waste oil and foreign substances are gradually moved from the lower part of the receiver 10 to the upper part as the cutting oil is continuously supplied. Thereafter, the decayed waste oil and foreign substances are discharged through the discharge unit 30 . The purified cutting oil that has moved through the slit S of the separator 20 also gradually rises and is recovered through the recovery unit 40 .

The receiver 10 receives the cutting oil used to process the material. The cutting oil used to process the material is gradually transformed into waste oil due to decay, etc. in the process of continuous use. Such waste oil further accelerates the decay of the cutting oil and reduces the quality of the cutting oil and shortens the lifespan. The receiver 10 may remove the waste oil and foreign substances suspended on the cutting oil, thereby recovering the purified cutting oil.

The coolant may be a water-soluble coolant. Water-soluble cutting oil is mixed with water in a certain ratio by adding an industrial emulsifier. Water-soluble coolant is used as a coolant in the process of cutting metal with metal cutting tools. Water-soluble cutting oil improves machinability by smoothing the cutting tool surface and increasing the tool lifespan when cutting metal with a metal cutting tool.

2 to 5 , the side wall part 110 may include a first side wall part 111 , a second side wall part 112 , a third side wall part 113 , and a fourth side wall part 114 . . The first side wall part 111 is disposed to face the fourth side wall part 114 . The second side wall part 112 is disposed to face the third side wall part 113 . That is, the first side wall part 111 , the second side wall part 112 , the third side wall part 113 , and the fourth side wall part 114 are disposed in a rectangular shape in plan view.

The oil separation device 1 according to an embodiment of the present invention further includes a guide plate 50 . The guide plate 50 is disposed to protrude from the third side of the side wall part 110 toward the inner space. On the other hand, the discharge unit 30 has an inlet 320 and an outlet 330 of the waste oil. In addition, the discharge part 30 extends in one direction (X) from the inlet 320 toward the outlet 330 . The guide plate 50 extends from the outlet 330 of the outlet 30 in the other direction Y toward the inlet 320 .

The guide plate 50 blocks the flow flowing along the longitudinal direction of the fourth side wall portion 114 in plan view. At the inlet 320 of the discharge unit 30, the flow rate is increased. Accordingly, the cutting oil in addition to the waste oil may be rapidly discharged together by the flow rate at the inlet 320 of the discharge unit 30 . In one embodiment, one end of the planar guide plate 50 is coupled to the fourth side wall part 114 , and the other end of the guide plate 50 is spaced apart from the other side wall part 110 . Thereby, the guide plate 50 causes the cutting oil to flow slowly from the receiver 10 to the inlet 320 of the discharge part 30 along the guide plate 50 . Accordingly, the waste oil may be discharged from the discharge part 30 of the guide plate 50 to the center.

The inlet 320 of the discharge part 30 is located lower than the uppermost surface of the guide plate 50 . In addition, the inlet 320 of the discharge part 30 is located lower than the top surface of the side wall part 110 . That is, the inlet 320 of the discharge part 30 is formed to be recessed toward the bottom part 100 from the uppermost surface of the guide plate 50 and the side wall part 110 . Accordingly, waste oil, foreign substances, etc. are naturally discharged at the height of the inlet 320 of the discharge unit 30 .

The guide plate 50 is spaced apart from the bottom part 100 by a predetermined height to form a slit. The guide plate 50 blocks the flow of cutting oil directly to the inlet 320 of the discharge unit 30 , and introduces purified cutting oil through the slit of the guide plate 50 . Accordingly, the level of the cutting oil is gradually increased, and waste oil and foreign substances suspended in the upper layer of the cutting oil may be discharged. In addition, the guide plate 50 may be spaced apart from the bottom part 100 by a second height. The second height is greater (higher) than the first height. Accordingly, the cutting oil supplied to the receiver 10 may be moved to the slit S of the separation plate 20 rather than the slit of the guide plate 50 in a predetermined water level range.

The inlet 420 of the recovery unit 40 is located lower than the uppermost surface of the separating plate 20 . In addition, the inlet 420 of the recovery unit 40 is located lower than the top surface of the side wall unit 110 . That is, the inlet 420 of the recovery unit 40 is formed to be recessed from the uppermost surface of the separation plate 20 and the sidewall 110 toward the bottom 100 . Thereby, the purified cutting oil is naturally recovered at the height of the inlet 420 of the recovery unit 40 .

In an embodiment, the discharge unit 30 includes a discharge plate 300 and discharge sidewalls 310 disposed at both edges of the discharge plate 300 . The discharge plate 300 is disposed to be inclined downward as it goes away from the receiver 10 . The recovery unit 40 includes a recovery plate 400 and a recovery side wall 410 . The recovery side wall 410 is disposed on both edges of the recovery plate 400 . The recovery plate 400 is disposed to be inclined downward as it goes away from the receiver 10 .
