[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid collecting apparatus for collecting a liquid such as oil from a container supported at a predetermined position.

[0002]

2. Description of the Related Art Oil tanks and the like of scrapped automobiles are subjected to recycling or shredder disposal after collecting the oil remaining inside. The reason for collecting oil in the tank in this way is that if there is residual oil, it will not be collected by a recycler, while if it is disposed of, the chips after shredder will be covered with oil, Because it is obligatory to bury chips containing oil in the soil, it takes a great deal of time to process them.

[0003] Conventionally, in order to recover the oil in the tank, a piercing tool disposed below the tank supported at a predetermined position is moved upward to pierce the bottom of the tank, and then pierced. The oil in the tank was allowed to flow downward through the hole to recover the oil.

[0004] However, only by draining the oil in the tank from the hole pierced by the piercing tool,
Since the outflow is caused only by the fall of the oil under its own weight, it takes a long time to recover the liquid in the oil, and there is a disadvantage that the liquid recovery efficiency is poor.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve such inconvenience, and a liquid capable of recovering a liquid in a container in a short time and improving the liquid collection efficiency. An object is to provide a recovery device.

By operating the air supply device 34a to supply the compressed air to the air supply holes 10b through the supply pipes 34, the compressed air passes through the air circulation holes 10 and is supplied to each air discharge hole 1b.
0a is discharged.

The XY table 14, as shown in FIG.
A lower table 35 and an upper table 36 slidably provided in the lower table 35 in the front-rear direction are provided. Two guide rails 37 extending in the front-rear direction are formed on the upper surface of the lower table 35 so as to be separated from each other in the left-right direction.
A guide portion 38 provided on the lower surface of 6 is slidably fitted.

Two guide rails 39 extending in the left-right direction are formed on the upper surface of the upper table 36 so as to be separated from each other in the front-rear direction. The guide rails 39 are provided on the lower surface of the base table 13. The part 40 is slidably fitted. Cylinders 41 and 42 are provided between the lower table 35 and the upper table 36 and between the upper table 36 and the base table 13, respectively. By operating these cylinders 41 and 42, the base table 13 moves in the front-rear and left-right directions so that the positioning of the first and second perforators 6 and 9 with respect to the oil tank T can be adjusted.

Next, a method of recovering oil in the oil tank T using the above-described oil recovery device 1 will be described. First, the base table 13 is moved by the XY table 14, and the first and second perforators 6, 9 are arranged below the oil tank T. At this time, the blade 24 of the upper blade portion 20 of the first punch 6 is
a, 24b (indicated by a two-dot chain line in FIG. 1) are arranged in the left-right direction and face the oil tank T.

Next, the first and second lifting cylinders 4, 7 are driven to extend the respective piston rods 5, 8. Then, as shown in FIG. 4, the bottom of the oil tank T is pierced by the upper blade 20 of the first drill 6 and the blade 31 of the second drill 9.

Next, the first punch 6 is rotated by the rotating device 12.
Is rotated 90 degrees in the direction of arrow a in FIG. 4 (see FIG. 5), and then the piston rod 5 of the first lifting cylinder 4 is contracted downward. Then, the peripheral edges of the obtuse portions facing each other of the oblique hole 43 pierced by the upper blade portion 20 are pierced from the inside of the oil tank T to the outside by the lower blade portion 21 as shown in FIG. A hole 45 having a burr 44 formed from the inside of the oil tank T toward the outside is formed on the inner periphery thereof.

At this time, the air supply hole 10 of the second piercing tool 9
b is supplied with compressed air from an air supply device 34a via a supply pipe 34.
And is discharged into the oil tank T from each air discharge hole 10b. As a result, the oil in the oil tank T flows out of the hole 45 along the burr 44 that is bent inward from the outside of the oil tank T together with the compressed air, is housed in the space A, and is sucked through the oil recovery hole 16. It is collected in a collection tank via a pipe 17 or the like.

After the oil in the oil tank T flows out, the oil remaining inside the oil tank T is vaporized by the compressed air and becomes a vapor. The gas flows out, is stored in the space B, and is collected from the vapor collection hole 18 into the collection tank via the suction pipe 19 and the like. Thereby, the oil in the oil tank T is completely recovered.

In the oil recovery device 1 having the above configuration,
From each air discharge hole 10b of the second piercing tool 9, the oil tank T
, And the oil in the oil tank T flows out from the hole 45 to the oil recovery box 2 together with the compressed air. Accordingly, the outflow speed of the oil flowing out of the hole 45 can be made faster than that of the conventional outflow caused only by its own weight , and the outflowing oil can be collected in the liquid collection box.
2 ensures the recovery . For this reason, the oil collection time can be shortened, and the oil collection efficiency is improved.

After the oil has flowed out of the oil tank T, the remaining oil adhering to the inside of the oil tank T is vaporized by compressed air to flow out of the hole 45. It is possible to prevent oil remaining inside and from dripping from the hole 45.

Further, the vapor flowing out of the hole 45 is
The suction pipe 1 is accommodated in the space B and
Since the harmful substance is contained in the collection tank through the tank 9 or the like, even if the harmful substance is contained in the oil, the substance can be prevented from being released to the atmosphere.

Further, the piston rod 8 of the second lifting cylinder 7 is lifted to break through the bottom of the oil tank T with the second piercing tool 9 and is compressed into the oil tank T from the air discharge hole 10a of the second piercing tool 9. Since the air is discharged, the air supply means 11 can be easily connected to any position of the oil tank T via the second piercing tool 9.

Further, since the oil and the vapor are caused to flow out from the inside of the oil tank T along the burr 44 which is bent outward, the oil and the vapor can flow out smoothly from the hole 45.

The present invention is not limited to the above embodiment, but can be changed as appropriate without departing from the scope of the present invention. For example, in the above embodiment, compressed air is used as the pressurized fluid, but instead, a pressurized cleaning liquid,
Pressurized hot water or pressurized steam or other pressurized fluid is discharged into the oil tank T and the oil tank T is discharged together with the pressurized fluid.
It is also possible for the oil inside to flow out of the hole 45 to the outside.

[0035]

As is apparent from the above description, according to the present invention, the pressurized fluid is discharged into the container by the pressurized fluid discharging means, and the liquid in the container is discharged together with the pressurized fluid into the first fluid. The liquid is discharged from the hole pierced by the punch into the liquid recovery box . Therefore, co the exit velocity of the liquid flowing out of the hole is a that faster than the outflow only with conventional free-fall
The liquid flowing out is reliably collected by the liquid collection box
Can be done . For this reason, the liquid recovery time is shortened, and the liquid recovery efficiency is improved.

Further, the second piercer is moved towards the container by the second moving means pierce the container by, were so as to discharge the pressurized fluid in the container from the front end portion of the second punch member
Thus , for example, even if the container does not have a portion for connecting the pressurized fluid discharge means such as an inlet, the pressurized fluid discharge means can be easily connected to the bottom of the container.
