The waste water with heavier specific gravity will converge towards the cylinder wall 321 of the cylinder member 32, and the grease and waste water that have been phase-separated will be pushed by the continuously replenished grease-containing waste water respectively, and the waste water at the periphery will move along the wall 321. The gap between the first conical disc member 41 and the top of the cylinder member 32 extends upward and is discharged to the outside of the cylinder member 32, so as to achieve the purpose of oil-water separation.

And as shown in FIG. 2 , the oil-water separator of the present invention is in the state of oil-water separation. At this time, the pressure fluid is continuously introduced from the channel 21 of the drive shaft 20 (as shown by the arrow), and the pressure fluid passes through the lead channels 311. When the flow is drained to the air chamber 511 , the piston 52 will be displaced toward the top cover 513 under the action of the pressure fluid (at this time, the elastic members 54 are compressed and contain a return elastic force), and link the connecting rods 53 , the valve unit 60, and keep the valve unit 60 in the first position, the valve unit 60 closes the slag discharge holes 322, the valve unit 60 rib 62 protrudes into the inside of the insert groove 36, and the air It is tightly pressed on the leakage blocking ring 34 .

As shown in FIG. 4 , when cleaning and slag removal are to be carried out, the pressure fluid is stopped from being introduced from the channel 21 of the drive shaft 20 . Once there is no pressing of the pressure gas, and the resilient force of the elastic members 54 is used, the The piston 52 will move toward the bottom case 512, and link the connecting rods 53 and the valve unit 60, and move the valve unit 60 to the second position, and make the slag discharge holes 322 open. When the cleaning liquid is introduced into the cylinder unit 30, the centrifugal action of the oil-water separation unit 40 is also used to throw the cleaning liquid out of the slag discharge holes 322, so as to achieve the purpose of cleaning and slag discharge.

After the cleaning is completed, the pressure fluid is introduced from the channel 21 of the drive shaft 20 again, and the piston 52 is pushed upward by the pressure gas and the connecting rods 53 are linked together, so that the valve unit 60 can be moved to the first position again. , and the slag discharge holes 322 are closed again, so that the oil-water separation operation can be continued.

Therefore, when the driving unit 50 is activated and the valve unit 60 is driven to make the slag discharge holes 322 open, in conjunction with the centrifugal action generated by the rotation of the drum unit 30 and the oil-water separation unit 40, automatic cleaning and automatic cleaning can be performed. Slag discharge, and no disassembly and assembly are required for slag discharge and cleaning, and the operation of slag discharge and cleaning is quite easy.

It is worth mentioning that the accommodating space 35 in the above-mentioned embodiment of the present invention is jointly defined by the mounting seat 31 , the cylindrical member 32 and the driving unit 50 . The surrounding wall (not shown) that extends upward and is butted with the bottom of the cylinder member 32, and only the accommodating space 35 is jointly defined by the mounting seat 31 and the cylinder member 32, and the cylinder of the driving unit 50 The 51 ring is arranged outside the mounting seat 31 .
