Description

Oil Separator

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-oil separator, and more particularly, to a water-oil separator capable of more reliably separating mixed oil mixed with a cutting oil and a sliding oil even if the separating tank is made small.

In general, almost all cutting machines, such as machining center (MCT) and CNC (computerized numerical control) lathes, require cutting oil to cool workpieces and slideway oil for lubrication during machine operation Is used.

Meanwhile, after the cutting oil and the hydraulic oil are used, they are mixed and stored in a recovery tank separately installed on one side of the cutting machine. If the cutting oil and the wetting oil are left mixed, the cutting oil is corrupted due to the sliding channel .

In order to solve the above problems, conventionally, a water separator for separating and separating the cutting oil and the sliding oil from each other using a difference in specific gravity between the cutting oil and the wet oil having different specific gravity is used.

FIG. 1 schematically shows a conventional oil water separator, which is generally mounted on a coolant tank 110 in which a cutting oil and a sliding oil are mixed and stored. And drives the drive pulley 210 and the differential pulley (not shown) to rotate the oil water separating belt 300.

The other end of the oil separating belt 300 is fixed to the inside of the coolant tank 110. When the oil is separated from the oil separating belt 300 by the rotation of the oil separating belt 300, And the mixed oil on the oil water separating belt 300 flows into the primary oil separating tank 120 by the blade of the oil guide plate 400 provided on the opposite side of the rotation.

The mixed oil flowing into the primary oil separation tank 120 sinks to the lower part due to the difference in specific gravity inside the primary oil separation tank 120, the sliding oil floats upwards and separates into layers, The cutting oil that has settled downward is discharged through a discharge pipe (not shown) installed inside the primary oil separation tank 120, The oil is separated and discharged to the secondary oil separation tank 130 through the means 121.

However, in the conventional oil water separating apparatus, when the capacity of the primary oil separating tank 120 is large, sufficient time is ensured for separating the mixed oil on the cutting oil and the sliding oil passage layer, When the capacity of the primary oil separation tank 120 is small, a sufficient time is not secured for separating the mixed oil on the cutting oil and the sliding passage layer, so that the unseparated mixture oil is discharged through the discharge pipe (not shown) The oil is discharged to the oil separation tank 130.

As described above, according to the present invention, the mixed oil introduced into the inlet tank 11 moves along the oil passage T formed by the oil passage extension forming member 40, and flows into the separating tank 12 while being separated from the cutting oil and the sliding oil passage. The mixed oil flowing into the separating tank 12 can be easily separated from the cutting oil and the sliding oil passage and even if the oil tank 11 is made compact by the oil passage forming member 40, It is possible to provide a sufficient time for the operation.

As a result, the separation tank 10 can be manufactured in a small size, thereby reducing manufacturing costs and space utilization.
