である。 Conventionally, this type of oil suction device consists of a tank connected to a vacuum pump, a workpiece connector connected to the tank via a connecting pipe, and an oil drain installed at the bottom of the tank with an on-off valve interposed in the middle. It is known that it is composed of a tube. In this oil suction device, after the pressure inside the tank is sufficiently reduced by a vacuum pump, the workpiece connector is connected to the oil outlet of the hydraulic equipment, and the residual oil inside the equipment is sucked into the tank by the negative pressure inside the tank. In addition, when more oil accumulates in the tank than the required amount, the inside of the tank is opened to the atmosphere, and a valve installed in the middle of the oil discharge pipe is opened, and the oil is discharged to the outside of the tank by its own weight. .
ところが、上記従来の油吸引装置にあつては、
真空ポンプが配管等を介してタンクに直結されて

あつた。 However, in the conventional oil suction device mentioned above,
Because the vacuum pump was directly connected to the tank via piping, there was a risk that oil sucked into the tank could flow into the vacuum pump and damage it. Further, when discharging the oil stored in the tank to the outside, only the weight of the oil is used to discharge the oil, which has the disadvantage of taking a long time.

リーナである。 An embodiment of the present invention will be described below with reference to the drawings. The drawing shows the schematic configuration of the entire oil suction device.
In the figure, reference numeral 1 is a frame divided into upper and lower parts. A vacuum pump 2 and a vacuum tank 4 connected to the vacuum pump 2 via piping 3 are arranged at the upper stage of the frame 1, respectively. The vacuum tank 4 has a built-in controller 5 that detects the pressure inside the vacuum tank 4 and turns the vacuum pump 2 ON and OFF according to the pressure value. The pressure inside the tank 7 is kept below the required pressure. In addition, 6
is a cleaner attached to the end of the exhaust pipe of the vacuum pump 2.

One side of the upper part of the oil tank 7 is connected to a switching valve 9 via a pipe 8, and this switching valve 9 is connected to the vacuum tank 4 via a pipe 10, and air is supplied via a pipe 11 and a regulator 12. It is connected to the source 13. and,
When the switching valve 9 is operated to move upward in the figure, the piping 8
and 10 are in communication and the pipe 11 is closed, and when the switching valve 9 is moved downward, the pipes 8 and 1 are connected.
1 and the pipe 10 is closed. The other side of the upper part of the oil tank 7 is connected to a workpiece connector 16 via a pipe 14 and a flexible tube 15. Work connector 16
is connected to the oil drain port of the object to be sucked, such as a disc brake, and is normally closed by an internal valve.The valve is operated only when connected to a workpiece, and the valve is automatically closed. It becomes open state.
Further, an oil discharge pipe 17 is connected to the lower part of the oil tank 7. Note that 18 and 19 are stop valves, and 20 is an oil level gauge.

圧力以下に保つている。 Next, a case will be described in which residual oil in a workpiece is sucked using the oil suction device configured as described above. First, close the stop valves 18 and 19 and move the switching valve 9 upward in the figure to close the pipes 8 and 19.
In this state, the vacuum pump 2 is started to reduce the pressure in the vacuum tank 4 and oil tank 7 to the required pressure. Next, open the stop valve 18 and connect the workpiece connector 16 to the workpiece.
Residues in the workpiece are sucked into the oil tank 7 by the negative pressure inside the oil tank 7. At this time, for some reason, such as when more than a predetermined amount of oil accumulates in the oil tank 7, the oil in the tank 7 may flow into the vacuum pump 2 side, which is the negative pressure source, but in this case, the oil in the tank 7 may flow into the vacuum pump 2 side, which is a source of negative pressure. A vacuum tank 4 is provided at , where:
Since the oil flowing in is collected, the same oil is transferred to the vacuum pump 2.
It will never reach that point. Further, since the vacuum pump 2 and the vacuum tank 4 are arranged above the oil tank 7, it is difficult for oil to flow from the oil tank 7 to the vacuum tank 4 side. Further, during oil suction, the vacuum pump 2 is turned ON and OFF by the controller 5 to keep the insides of the vacuum tank 4 and the oil tank 7 at a required pressure or lower at all times.

に油排出管１７を介して外部に払い出される。 When the oil suction work is completed or more oil than required has accumulated in the oil tank 7, the connecting tool 16 is removed from the workpiece, the stop valve 18 is closed, the stop valve 19 is opened, and the switching valve 9 is closed. Move downward in the diagram. Accordingly, the oil tank 7 is cut off from the vacuum tank 4, and air is supplied from the air supply source 13 through the pipe 11 into the oil tank 7. Therefore, the oil stored in the oil tank 7 is pushed out by the pressurized air in addition to its own weight, and is discharged to the outside via the oil discharge pipe 17 within a very short time.

る。 As explained above, according to the present invention, since the vacuum tank is interposed between the vacuum pump and the oil tank, the oil sucked into the oil tank does not reach the pump, and the oil does not flow in. Damage to the vacuum pump caused by this can be avoided. Further, by providing a vacuum tank, the capacity of the vacuum system can be increased, and even when a certain amount of oil is stored in the oil tank, the pressure of the vacuum system can be kept relatively low. Furthermore, since the vacuum tank is connectably connected to the oil tank, and the air supply source is connectably connected to the oil tank,
The oil in the oil tank can be discharged using pressurized air, and has excellent effects such as being able to significantly shorten the time required for discharging.
