In addition, the working cylinder 400 is the front end of the rear end fixed to the rotating shaft 430 is installed in the flow guide box 420 to be rotatable flow, for example, always inside the flow guide box 420 It has a structure in which the expansion spring 470 to try to suppress the operation cylinder 400 in the counterclockwise direction is built into the toothed gear 220 of the rotating member 200 at all times when the hook 450 is moved forward. It is desirable to zoom in as much as possible.

In particular, the stroke of the operation cylinder 400 is preferably adjusted to rotate the rotary member 200 by 120 ° from the initial point every one operation.

The operating relationship of the present invention made of such a configuration is as follows.

First, a plurality of coalescing balls (B) having excellent oil absorption power are injected into an upper portion of the oil wastewater storage tank 2.

Therefore, the waste oil floating on the upper surface of the oil waste water storage tank 2 due to the specific gravity difference is absorbed by the coalescing ball (B).

The driving motor 300 is driven at the time of the oil absorption action of the coalescing ball (B), and as a result of the rotation of the belt 340, the bucket 350 attached thereto is to raise a plurality of coalescing balls (B) do.

The coalescing ball (B) that is moved upward is dropped while the bucket 350 is inverted, and is introduced into the cylindrical chamber 210 along the guide guide 360 after the drop.

At this time, since the lower surface of the cylindrical chamber 210 is blocked by the base frame 100, the coalesced ball B dropped and introduced is accumulated in the cylindrical chamber 210.

When a certain time has elapsed (timer adjustment) or when the filling state of the coalescing ball B is confirmed by a detection sensor, the driving motor 300 is stopped and at the same time the operation cylinder 400 is advanced.

The snap grip rod 410 is advanced in accordance with the forward operation of the operation cylinder 400 to be positioned at the hook 450 at a point capable of rotating the rotating member 200 by 120 °.

In this process, the operation cylinder 400 is rotated in the clockwise direction by the expansion force of the expansion spring 470 that is compressed to maintain a stable contact state without the hook 450 is separated from the rotating member 200.

Subsequently, the operation cylinder 400 is retracted and the hook 450 is retracted while being caught by the toothed gear 220 of the rotating member 200.

Therefore, since the rotating member 200 is also rotated 120 ° in the counterclockwise direction, the cylindrical chamber 210 filled with the coalescing balls B has its lower end coinciding with the drain line 134 and the squeeze cylinder 150 at the upper side thereof. Will be placed.

At the same time, the operation cylinder 400 is rotated counterclockwise around its rotation axis 430 by the interference of the retracted hook 450 and the toothed gear 220 of the rotating member 200 expansion spring 470 Will be compressed and returned to its original position.

When the operation is completed, the squeeze cylinder 150 is lowered and the compression plate 154 presses the coalescing ball B to squeeze the oil absorbed in the coalescing ball B.

Since the squeezed oil is discharged through the drain line 134, the coalescing ball B is placed in a state capable of absorbing oil again.

When the oil squeeze operation is completed, the operation cylinder 400 is restarted and the above-described operation is repeated. Accordingly, the cylindrical chamber containing the oil squeezed coalescing ball B is matched with the coalescing ball outlet 120. .

When the return of the operation cylinder 400 is completed, the supply of pneumatic pressure through the purge line 124 at the same time as the discharge cylinder 140 is lowered, the coalescing ball (B) smoothly along the input line 122 oil waste water storage tank If it is re-injected into (2), the above-described process is repeated continuously.

As described in detail above, according to the present invention, by using the coalescing ball having a good oil absorption force, the oil floated to the upper part of the waste water can be easily adsorbed and removed to separate the oil and the waste water quickly. And perfect, thereby preventing water pollution and improving productivity.
