Example one

As shown in fig. 1 to 4, the compressor includes a shell 10, a discharge end cover 20 and a discharge oil distributing pipe 60, wherein the shell 10 has a receiving cavity, the discharge end cover 20 is located at one side of the shell 10, one side of the discharge end cover 20 facing the receiving cavity has an inner discharge area 30 and an outer ring oil storing area 40 which are nested, the inner discharge area 30 and the outer ring oil storing area 40 are separated by a partition rib 50, a communication structure 51 is provided on the partition rib 50, so that the inner discharge area 30 and the outer ring oil storing area 40 are communicated by the communication structure 51, the discharge oil distributing pipe 60 is arranged in the outer ring oil storing area 40, and at least one end of the discharge oil distributing pipe 60 has an opening structure.

Because the inner exhaust area 30 and the outer ring oil storage area 40 are arranged on one side of the exhaust end cover in an embedded mode, the inner exhaust area 30 and the outer ring oil storage area 40 are separated, exhaust and oil return are enabled to run through different loops, oil liquid after oil-gas separation is reduced during exhaust, abrasion of the compressor caused by oil liquid shortage in the running process is reduced, and the service life of the compressor is prolonged. The inner exhaust area 30 and the outer oil storage area 40 are both of annular structures, which is more beneficial to the oil-gas mixture to do high-speed centrifugal motion, so that oil-gas separation is realized. The communicating structure 51 on the partition rib 50 enables the oil-gas mixture in the inner exhaust area 30 to enter the outer ring oil storage area 40 for centrifugal movement, the separated gas flows out of the compressor through the exhaust oil distributing pipe 60, and the separated oil drops into the outer ring oil storage area 40. Compared with the traditional vertebral canal oil distribution, the air compressor saves space, reduces exhaust pressure drop without orifice throttling, and improves the efficiency of the compressor.

As shown in fig. 2, the exhaust gas manifold 60 is of an arc-shaped configuration to fit the outer ring oil storage area 40. The exhaust gas manifold 60 is configured in an arc-shaped configuration to facilitate the flow of the separated gas through the exhaust gas manifold 60.

As shown in fig. 2, the spacer ribs 50 are of an arc-shaped structure, and both ends of the arc-shaped structure are spaced apart from each other to form a communicating structure 51. The communicating structure 51 allows the air-fuel mixture in the inner exhaust region 30 to enter the outer ring oil reserving region 40 for centrifugal movement.

It should be noted that, in the embodiment shown in fig. 2, the exhaust gas manifold 60 is disposed corresponding to the communicating structure 51. Thus, the oil-gas mixture discharged through the communicating structure 51 is in contact with the exhaust gas branch pipe 60 at the first time to perform oil-gas separation.

Of course, in an alternative embodiment not shown in the drawings, the communicating structure 51 may also be a communicating groove or a communicating hole provided on the partition rib 50.

As shown in fig. 2, the compressor further includes a baffle plate 70, and the baffle plate 70 is disposed in the outer ring oil storage region 40 and connected to the inner ring side 41 and the outer ring side 42 of the outer ring oil storage region 40. The guide baffle 70 enables the oil-gas mixture to move along a certain fixed direction, so as to prevent the oil-gas mixture from flowing in the opposite direction, and the separated gas is rapidly discharged from the compressor.

As shown in fig. 1, the inner exhaust region 30 and the outer ring oil sump region 40 are each formed by a recess provided in the exhaust end cover 20, and a spacer 50 is formed therebetween. An exhaust valve plate assembly 31 is arranged outside the inner exhaust area 30, and after the oil-gas mixture exhausted at high temperature and high pressure passes through the exhaust valve plate assembly 31, the oil-gas mixture is converged in the inner exhaust area 30 and then is exhausted at high speed through a communication structure 51 above the inner exhaust area 30. After the oil-gas mixture enters the space above the outer ring oil storage area 40, the oil-gas mixture performs high-speed centrifugal motion around the exhaust oil distribution pipe 60, and heavy oil drops are gathered on the outer wall of the passage and flow to the lower part of the outer ring oil storage area 40 under the action of centrifugal force. At the same time, the high velocity gas exits the compressor through an open structure in the discharge manifold 60.

As shown in fig. 1, the depth of the recess corresponding to the inner exhaust region 30 is greater than the depth of the recess corresponding to the outer oil reserving region 40. Since the volume of the air-fuel mixture is much larger than that of the separated oil, the volume of the inner exhaust region 30 needs to be designed to be larger than that of the outer oil storage region 40 to accommodate a large amount of air-fuel mixture.

As shown in fig. 1, 3 and 4, the compressor further includes a movable and stationary disc assembly and a bracket 100, wherein the movable and stationary disc assembly is located in the accommodating cavity, the exhaust hole on the stationary disc 90 of the movable and stationary disc assembly is communicated with the inner side exhaust area 30, the stationary disc 90 has a stationary disc oil return hole 91 communicated with the outer ring oil storage area 40, the bracket 100 is located on one side of the movable and stationary disc assembly away from the exhaust end cover 20, the bracket 100 has a bracket oil return hole 101, one side of the stationary disc 90 facing the bracket 100 has a stationary disc pressure drop groove 92, and the stationary disc oil return hole 91 is communicated with the bracket oil return hole 101 through the stationary disc pressure drop groove 92. Separated oil liquid is gathered below the outer ring oil storage area 40 and then enters a static disc pressure drop groove 92 between the static disc 90 and a support 100 through a static disc oil return hole 91 formed in the static disc 90, and the oil liquid is fully mixed with low-pressure gas through a support oil return hole 101 formed in the upper portion of the support 100 and communicated with the static disc pressure drop groove 92 after pressure reduction, so that lubrication is provided for the static disc component.

Specifically, the stationary disc oil return hole 91 extends in the axial direction of the stationary disc 90, and the stationary disc pressure drop groove 92 extends around the circumferential direction of the stationary disc 90.

As shown in fig. 1, the stationary disk 90 has a stopper rib 93 projecting toward the exhaust end cover 20, and the stopper rib 93 corresponds to the spacer rib 50 to separate the inner exhaust region 30 from the outer ring oil sump region 40.

Specifically, the bracket oil return hole 101 is located in the suction flow passage of the compressor. Thereby make fluid and low-pressure gas intensive mixing, promote lubricated effect.

Example two

Difference from the first embodiment is as shown in fig. 5 and 6, the compressor further includes an exhaust pipe mounting block 80, and the exhaust pipe mounting block 80 is provided at one end of the exhaust gas manifold 60. The exhaust pipe mounting block 80 functions in accordance with the flow guide baffle 70 of the first embodiment to prevent the reverse flow of the gas-oil mixture, so that the separated gas is rapidly discharged from the compressor.

EXAMPLE III

The difference with embodiment one is as shown in fig. 7, both ends of exhaust oil distribution pipe 60 all set up open structure, and both ends all do not have the structure of keeping off a current, and bilateral exhaust oil distribution pipe 60's setting has increased gaseous flow area, has reduced the gas pressure drop, has prolonged the oil distribution region simultaneously for oil gas can more abundant separation, has promoted the oil distribution effect.
