Therefore, the stock solution discharged through the stock solution tube 24 is rotated in the rotating bowl 7 to form a layer for each water phase having different specific gravity as shown in FIG. 2 by centrifugal force.

Next, the disk 8 and the upper disk hood 9 will be described.

The disk 8 is a known configuration in which the plurality is stacked at regular intervals and is disposed on the outer circumference of the vertical axis of rotation 4. Of course it is housed in the rotating bowl 7. Since the structure is similar to the conventional structure, detailed description thereof will be omitted.

The upper disk hood 9 is coupled to the upper portion of the disk 8 while covering the disk 8, and the upper disk hood 9 may also have a substantially conical disc shape. Therefore, the lower inclined surface of the upper disk hood 9 has a structure capable of inducing oil upward and the upper inclined surface to induce water upward.

Next, the water chamber 10 is coupled while the stock solution feeding tube 16 penetrates in the center thereof, forms a disc shape, and is coupled to an upper portion of the rotating bowl 7 to seal the rotating bowl 7 and at the same time, Holes are formed to communicate with the upper and lower surfaces of the upper disk hood 9.

It is formed, the adjustment bolt (25A) is to be inserted into the control hole (25B) is fastened.

Therefore, when the control bolt 25A is completely fastened to completely block the heavy liquid discharge pipe 14A, oil is discharged only to the hard fluid discharge pipe 23A to perform three phase separation.

On the contrary, when the control bolt 25A is dismantled to open the heavy liquid discharge pipe 14A, four phase separation is performed.

Therefore, the three or four phases can be selectively operated by manipulating the adjusting bolt 25A according to the type of water phase to be separated by one machine.

The following briefly describes the process of operating the present invention in each of the three phase and four phase.

First, in the case of three phase separation, the vertical rotation shaft 4 rotates when the control bolt 25A is completely fastened (clockwise) and then driven by the motor 1 to supply power.

When the stock solution is introduced into the stock solution inlet 15, the stock solution feed tube 16, the stock solution flow passage 4A, and the stock solution opening 24 are supplied into the rotary bowl 7.

The supplied stock solution is separated by oil, water, and sludge from the inside according to specific gravity in the rotary bowl 7 by centrifugal force.

At this time, the oil is led to the lower inclined surface of the upper disk hood 9 along the disk 8 to the oil blocking ring plate 21B and then lowered through the oil guide groove 17 and then the oil separating plate 18. 2) is introduced into the hard fluid discharge pipe 23A, and is discharged to the hard fluid discharge pipe 23A by centrifugal force by a high speed rotation and is recovered to the hard fluid discharge port 23B.

By the water discharge pipe 12 is discharged to the water discharge port 13 by.

Sludge is deposited on the inner outer wall of the rotary bowl 7 so that it can be finally removed after the work is completed.

Second, in the case of four-phase separation, the control bolt (25A) is dismantled (counterclockwise operation) to open the heavy liquid discharge pipe (14A) and then rotate the rotating bowl (7) at high speed.

Similarly, when the stock solution is supplied into the rotary bowl 7, a separation layer of hard liquid, heavy liquid (ideal oil), water, and sludge is formed from the inside.

Hard liquid, water, and sludge are separated and collected in the same manner as in the three phases described above, and the heavy liquid is recovered to the heavy liquid discharge port 14B through the heavy liquid discharge pipe 14A.
