Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

Referring to the attached drawings 1 to 3, in the present embodiment, a high efficiency oil-gas separator with multiple oil-gas separation functions includes a cylinder 1, an air inlet pipe 11 connected to an upper portion of a side wall of the cylinder 1, an air outlet pipe 12 connected to a top portion of the cylinder 1, and an oil drain pipe 13 connected to a lower portion of the side wall of the cylinder 1, wherein the air outlet pipe 12 is vertically extended and a port thereof extends through an inner cavity of the cylinder 1; the air inlet pipe 11 penetrates and extends to the inner cavity of the cylinder 1 along the tangential direction of the cylinder 1; the oil drain pipe 13 port extends to the bottom of the inner cavity of the isolation sleeve 2.

Further, the port of the air inlet pipe 11 is an upper inclined plane port facing upwards to the top of the inner cavity of the cylinder 1.

In this embodiment, the top of the inner cavity of the cylinder 1 is provided with a separation sleeve 2 which extends downwards to form a lower opening, wherein the separation sleeve 2 is in a cylindrical shape, and the top of the separation sleeve 2 and the top of the inner cavity of the cylinder 1 are fixed together in a spot welding manner. In addition, the port of the air inlet pipe 11 is located between cavity regions defined by the outer wall of the isolation sleeve 2 and the inner wall of the barrel body 1, and therefore high-pressure oil-gas mixture enters the cavity regions defined by the outer wall of the isolation sleeve 2 and the inner wall of the barrel body 1 through the air inlet pipe 11 to flow centrifugally, so that under the action of gravity and centrifugal force, the high-pressure oil-gas mixture is subjected to primary oil-gas separation, and separated lubricating oil is attached to the wall surface and gradually flows to the bottom of the barrel body 1 to be collected.

In this embodiment, the port of the exhaust pipe 12 extends to the inner cavity of the isolation sleeve 2. The inner cavity of the isolation sleeve 2 is provided with a separation partition plate 3 positioned below the port of the exhaust pipe 12, and the separation partition plate 3 is formed with a plurality of filter holes 31. The high-pressure oil-gas mixture after primary oil-gas separation enters the inner cavity of the isolation sleeve 2 through the lower outlet of the isolation sleeve 2, and secondary oil-gas separation is carried out in the inner cavity of the isolation sleeve 2 from bottom to top through the filtering holes 31 of the separation partition plate 3. Secondly, the diameter width of the separating partition plate 3 is matched with the inner diameter of the isolating sleeve 2 so as to be convenient for fixedly installing the inner cavity of the isolating sleeve 2, the separating partition plate 3 has a certain inclination degree to be obliquely arranged in the inner cavity of the isolating sleeve 2, and the inclination angle range is 3-10 degrees, so that the separating partition plate 3 adopts an oblique arrangement mode so that the separated lubricating oil can smoothly flow to the bottom of the barrel body 1.

Further, the separating partition 3 is positioned at the middle upper part of the inner cavity of the isolating sleeve 2.

Further, the diameter of the filtering hole 31 is 3-10 mm.

In this embodiment, the space in the inner cavity of the isolation sleeve 2 above the separation partition 3 is filled with a filter net group 4, wherein the filter net group 4 is densely distributed by a plurality of stainless steel wires into a net group shape, and the width of the stainless steel wires is 2-4 mm. The high-pressure mixture after the secondary oil-gas separation passes through the filter screen group 4 from bottom to top to carry out the tertiary oil-gas separation.

The lubricating oil separated by the separation baffle 3 and the filter screen group 4 flows to the bottom of the cylinder 1 to be collected

In this embodiment, the high-pressure oil-gas mixture firstly undergoes centrifugation and frontal collision between the cavity region defined by the outer wall of the isolation sleeve 2 and the inner wall of the cylinder 1 to realize primary oil-gas separation, then the high-pressure oil-gas mixture enters the isolation passage from bottom to top and passes through the filtering holes 31 of the separation partition plate 3 to realize secondary oil-gas separation, finally the high-pressure oil-gas mixture passes through the filtering net group 4 to realize tertiary oil-gas separation, and finally high-pressure refrigerant steam after the tertiary oil-gas separation is output to the refrigerant circulation system through the exhaust pipe 12. The oil-gas separation efficiency of the refrigerant can be greatly improved after three times of oil-gas separation, and meanwhile, the excessive refrigerant flowing resistance cannot be increased.

Further, the lubricating oil collected at the bottom of the cylinder 1 returns to the compressor through the oil drain pipe 13, and the corresponding lubricating oil level is maintained.

Referring to fig. 2, in the present embodiment, the isolation sleeve 2 may be formed with an avoiding groove 21 in a concave manner at a position opposite to the port of the intake pipe 11, so as to reduce the flow resistance of the high-pressure oil-gas mixture fed into the intake pipe 11.
