Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a rational construction of an oil / water separator for waste oil installed in a machine tool.

[0002]

[Prior art and problems]

 BACKGROUND ART Conventionally, an oil / water separation device for waste oil installed in a machine tool or the like is known as a tank device that separates and collects lubricating oil and a coolant. Most of the conventional oil-water separation devices are floor-standing systems and require a large installation floor area. Moreover, since the height dimension is smaller than the width of the oil-water separator, the separation effect between the lubricating oil and the coolant is not good even if multiple separators are installed. Furthermore, the oil / water separation device must be separated from the machine body when the machine tools are relocated and moved due to the layout change of the factory, which makes the movement work troublesome.

[0003]

[Problems to be solved by the device]

 In view of the problems of the conventional oil / water separator for waste oil, an object of the present invention is to provide a thin oil / water separator which is reasonably configured so that it can be attached to a machine body.

[0004]

[Means for Solving the Problems]

 The present invention provides a thin, elongated, and deep-sized separation container, which is equipped with a fitting for attaching one side of the separation container to the machine body, and further a plurality of oil-water separation plates in the separation container. The waste oil oil-water separation device is constructed by arranging a waste oil discharge port and a coolant discharge port, which are slightly lower than the waste oil discharge port, on opposite side walls in the longitudinal direction of the separation container.

Since the oil-water separator for waste oil of the present invention is thin, it can be directly attached to the side wall surface of the machine body and integrated with the machine. In addition, since the separation container is a long, narrow and deep shape, and the discharge port for waste oil and the discharge port for coolant, which is slightly lower than this, are placed opposite to each other on both side walls in the longitudinal direction of this separation container, the oil-water separation action of waste oil is also efficient. Done.

【Example】

 Hereinafter, an example shown in the drawings will be described. FIG. 1 is a side sectional view of an oil / water separator for waste oil according to the present invention, and FIG. 2 is a plan view of the present invention viewed from different directions.

In FIGS. 1 and 2, reference numeral 1 is a side wall surface or a bracket of a machine tool, to which an oil / water separating device 100 of waste oil of the present invention is attached by bolts 2 and 2. The oil / water separator is a thin, elongated, deep-separated separation container 10, and the separation container is provided with fittings 3, 4 for attaching the one side surface 10a to the machine body 1 so as to attach it. Further, a plurality of oil / water separation plates 5 ..., 6 are planted in the separation container 10, and waste oil discharge ports 7 are provided on both side walls 10b, 10c in the longitudinal direction of the separation container 10. This is an oil / water separation device for waste oil in which a coolant discharge port 8 is arranged slightly lower and a drain port 9 for cleaning is provided on a bottom surface 10d of a separation container 10. The three oil-water separating plates 5 are arranged in the separating container 10 and are alternately attached to the front and rear side wall surfaces 10a and 10a ', and the free edge thereof forms a proper gap X with the side wall surface 10a or 10a' on the other side. It is provided. Further, the oil / water separating plate 6 is laid between the front and rear side wall surfaces 10a and 10a 'so as to close the left and right sides, and an appropriate gap Y is provided between the oil and water separating plate 6 and the bottom surface 10d as shown in FIG.

However, the waste oil OW, which is a mixture of the lubricating oil and the coolant, is discharged from the pipe 11 to an appropriate position on the left side (in the figure) of the separation container 10, and the coolant CW having a high specific gravity is accumulated on the lower side and the waste oil OW is accumulated on the upper side. Lubricating oil O with a low specific gravity accumulates. At this time, since one side of the oil / water separation plate 5 is open and connected regardless of the height position, the coolant C W having a large specific gravity is accumulated on the lower side and the lubricating oil O having a small specific gravity is accumulated on the upper side to form a double layer. To do. Then, the lubricating oil O in the upper layer is naturally discharged from the discharge port 8 to the outside. On the other hand, since the oil / water separation plate 6 has an open bottom, only the coolant CW having a high specific gravity is collected and naturally discharged from the discharge port 8 to the outside.

In the above operation, it should be noted that the separation container 10 which is thin, long and slender and has a deep shape is formed, and therefore the oil-water separation operation in the deep separation container is completely performed up and down. In the elongated separation container, the lubricating oil O having a low specific gravity moves slowly in the maze partitioned by the oil / water separating plate 5, and the coolant CW having a large specific gravity is precipitated, so that the oil / water separating action is completely performed up and down. In addition, the oil-water separation action can be performed by the oil-water separation device 100 having the compact and thin separation container 10.

It is needless to say that the present invention is not limited to the above-mentioned one embodiment, and design changes can be made within the scope of the invention.

[0011]

【effect】

 Since the oil-water separator of waste oil of the present invention is thin, it can be directly mounted on the side wall surface of the machine body, takes up almost no installation area, and can be integrated with the machine even when the layout is changed, improving work efficiency. In addition, since the separation container has a long, narrow and deep shape, and the waste oil discharge port and the coolant discharge port, which are slightly lower than this, are placed opposite to each other on both longitudinal walls of the separation container, the oil-water separation action of the waste oil is also efficient. Well done.
