[0045] Preferably, the oil-gas separation device consists of two parts: an oil discharge chamber 9 and a separation device. The oil discharge chamber 9 is located inside the barrel body 8, specifically above the base 11, below the partition 4, and outside the circle 7.

[0046] Preferably, the separation device includes a cylinder 7 located inside the barrel 8 and welded to the lower surface of the partition 4 at its top. The cylinder 7 is a welded steel pipe. An oil-gas separation filter element 5 is disposed inside the cylinder 7.

The coarse separation chamber 17 is specifically the part inside the cylinder 7, below the partition 4 and outside the oil-gas separation filter element 5. A fine separation chamber 6 is also disposed inside the oil-gas separation filter element 5.

[0047] Preferably, the flange of the oil-gas separator filter element 5 is placed on the partition plate 4, and a pressure plate 3 is provided on the partition plate 4. The pressure plate 3 is placed on the flange of the oil-gas separator filter element 5, and the pressure plate 3 and the oil-gas separator filter element 5 are fixed on the partition plate 4 by bolts.

[0048] Preferably, the partition 4 has a circular hole in the center, and the upper surface of the partition 4 has a ring of evenly distributed threaded holes, wherein the threaded holes are not through; the pressure plate 3 has a ring of evenly distributed through holes, and the pressure plate 3 has a pressure plate through hole 13 in the center.

[0049] Preferably, the sealed barrel includes a cap 1, a cap flange 2, a barrel body 8, and a base 11. The cap 1 has a ring of evenly distributed through holes.

[0054] The bottom of the oil discharge chamber 9 is the sedimentation chamber for lubricating oil, where the separated lubricating oil will accumulate; the oil outlet connector 10 is connected to the bottom of the sedimentation chamber, and the lubricating oil is discharged from the oil-gas separator through the oil outlet connector 10.

[0055] After coarse separation, the oil-gas mixture enters the coarse separation chamber 17 and passes through the oil-gas separation filter element 5. Fine separation is performed when passing through the oil-gas separation filter element 5, and a relatively clean gas is obtained in the fine separation chamber 6. The clean gas passes through the pressure plate through hole 13, the exhaust chamber 12 and the exhaust pipe 14 in sequence and is finally discharged from the oil-gas separator.

[0056] The oil-gas separator of this oil screw vacuum machine separates the oil and gas in the oil-gas mixture. The separated lubricating oil is cooled and filtered before being recycled back into the main unit. The separated gas is discharged from the vacuum machine, which greatly improves the utilization rate of lubricating oil, saves costs, and helps ensure the stable and reliable operation of the oil screw vacuum machine.
