Reference numeral 25 denotes a handlebar provided on the side edge of the carriage 4, and reference numeral 26 denotes an operation panel attached to the handlebar 25.

Reference numeral 27 denotes a scattering prevention net, which is laid in the tray 19.

Reference numeral 28 denotes an external container, that is, an oil reservoir of a vehicle engine, and 29, a waste liquid storage tank, that is, a waste oil storage tank.

Next, functions and operations of the waste liquid treatment apparatus 1 according to the embodiment will be described.

The waste liquid treatment apparatus 1 has a function of efficiently extracting engine oil or other waste liquid from a maintenance vehicle using a suction or receiving tray, and efficiently transferring the extracted waste liquid to another waste liquid tank provided. have.

That is, when draining the engine oil by suction, the waste liquid treatment apparatus 1 is moved and installed near the engine of the maintenance vehicle.

Then, the distal end of the introduction pipe 7 connected to the first closed container 2 is inserted into an insertion hole 28 a (oil level gauge hole or the like) provided in the oil reservoir 28 of the engine.

Next, when the three-way switching valve 13 is operated to send the compressed air from the main air pipe 11 to the ejector 14, the negative pressure generated in the ejector 14 is transmitted through the suction pipe 18 to the first closed container 2. To reduce the pressure inside the first closed vessel 2 to the atmospheric pressure or less. At this time, the first on-off valve 5 is closed.

Thus, the oil in the oil reservoir 28 is drawn into the first closed container 2 through the introduction pipe 7.

However, since the amount of waste oil in the first closed container 2 can be determined by the level gauge 23 provided in the first closed container 2, when the first closed container 2 is full, the first closed container 2 is filled. The waste oil in the closed container 2 is transferred to the adjacent second closed container 3.

Incidentally, the second closed container 3 has a capacity several times larger than that of the first closed container 2.

That is, when transferring waste oil from the first closed container 2 to the second closed container 3, the operation of the ejector 14 is stopped, the first on-off valve 5 is opened, and the first The closed container 2 and the second closed container 3 communicate with each other.

Next, the three-way switching valve 13 is operated to supply the compressed air from the main air pipe 11 to the first closed vessel 2 through the second branch pipe 17, thus pressurizing the inside of the first closed vessel 2. Thereby, the waste oil in the first closed container 2 is transferred to the second closed container 3 through the connecting pipe 6.

When the second closed container 3 is full, the waste liquid treatment device 1 is moved to and installed near the waste oil storage tank 29.

Then, the first opening / closing valve 5 is closed and the third opening / closing valve 10 is opened so that the second closed container 3 and the oil drainage storage tank 29 are communicated by the discharge pipe 8.

Next, the second air on-off valve 16 is opened to supply the compressed air from the main air pipe 11 to the second closed vessel 3 through the first branch pipe 15. By pressurizing, the waste oil in the second closed container 3 is discharged to the waste oil storage tank 29 through the discharge pipe 8.

Next, when draining the engine oil using the tray 19, the maintenance vehicle is lifted up and the waste liquid treatment apparatus 1 is moved under an oil sump (oil pan) attached to the engine of the vehicle. To place.

Then, waste oil is allowed to flow down into the tray 19 through a drain hole at the bottom of the oil pan.

A scattering prevention net 27 is provided in the tray 19 to prevent the falling waste oil from scattering.

The waste oil stored in the receiving pan 19 descends into the second closed container 3 via the inflow pipe 20, and the check valve 21 interposed in the inflow pipe 20 causes the gas from the second closed vessel 3 to flow. In addition, the liquid is prevented from flowing back, and the waste oil is formed such that there is almost no resistance to flowing down into the second closed container.

It is to be noted that the waste liquid is extracted using the receiving tray 19 when the diameter of the insertion hole 28a provided in the oil reservoir 28 of the engine is too small and the introduction pipe 7 cannot be inserted into the insertion hole 28a. This is an effective method.
