[0030] Embodiment 1

[0031] Please refer to Figs. 1-3 The application provides a compressor facilitating oil gas separation, which comprises a shell 10, a compression pump 3, an oil storage cavity 5 and an oil gas separation assembly arranged in the shell 10, the oil gas separation assembly is located above the outlet of the compression pump 3, the oil storage cavity 5 is located below the compression pump 3, the inside of the oil storage cavity 5 is provided with a liquid channel, the lubricating oil is transmitted to each shaft part for lubrication along the liquid channel, and then returned to the inside of the oil storage cavity 5 after lubrication.

[0032] The oil gas separation assembly in the application comprises a circular separation net 1, the center of the circular separation net 1 is convex to the side of the oil gas movement direction, and the circular separation net 1 is provided with separation holes 7; the center of the circular separation net 1 is provided with a crankshaft 2, and the crankshaft 2 can drive the circular separation net 1 to rotate. In the application, the circular separation net 1 is located above the compression pump 3, that is, the high-pressure gas output by the compression pump 3 moves upward, therefore, the center of the circular separation net 1 is convex upward, that is, the whole circular separation net 1 is buckled above the compression pump 3 like an umbrella.

[0033] The circular separation net 1 is provided with M separation bands extending along the radial direction, and each separation band comprises N separation holes 7; M and N are both integers greater than 0. The separation hole 7 is a through hole penetrating the circular separation net 1, and the gas mixed with the lubricating oil output by the compression pump, that is, the oil gas mixture needs to pass through the circular separation net 1 to continue to move upward to the exhaust port 8, as shown in the attached drawings. Fig. 1As shown by the middle arrow, when the oil-gas mixture passes through the circular separation net 1, the gas directly passes through the separation holes 7 due to the rotation of the circular separation net 1; the lubricating oil is divided into two cases: the first case, the lubricating oil touching the lower surface of the circular separation net 1 is thrown out under the centrifugal force, wherein the thrown-out lubricating oil can flow back and drop to the oil storage cavity 5 along the lower surface of the circular separation net 1; it can also pass through the separation holes 7 during the throwing process, and then flow back and drop to the oil storage cavity 5 along the upper surface of the circular separation net 1 under the action of gravity and centrifugal force. The second case, the lubricating oil directly passes through the separation holes 7, and is affected by gravity and centrifugal force during the process of passing through the separation holes 7, and flows back and drops to the oil storage cavity 5 along the upper surface of the circular separation net 1.

[0034] The diameters of the separation holes 7 in the separation zone gradually increase in the first direction, wherein the first direction refers to the direction from the center to the edge of the circular separation net 1. The reason for setting different diameters is that the outlet of the compression pump 3 is close to the middle position of the circular separation net 1, so when the gas discharged by the compression pump 3 is discharged upward, the gas pressure at the center of the circular separation net 1 is large and the flow rate is fast, and the diameter of the separation hole 7 at the middle position is small, which can reduce the gas flow and prevent a large amount of lubricating oil from being discharged with the high-pressure gas; the small-diameter separation hole 7 ensures that the oil-gas mixture with high pressure and fast flow rate can be fully separated, and at the same time, the large-diameter separation hole 7 at the edge enables the oil-gas mixture with small pressure and slow flow rate to pass through the separation hole 7 quickly and timely to the exhaust port 8 for discharge; the diameter division setting of the present application can not only ensure the full separation of oil and gas, but also ensure that the gas output by the compression pump 3 does not stay in the compressor for too long, and is discharged in time, without affecting the normal use performance of the compressor.

[0035] Due to the large pressure and fast flow rate of the oil-gas mixture at the center of the circular separation net 1, in order to ensure that it can be fully output, while setting the small-diameter separation hole 7, a separation hole 7 with a larger density can also be set, that is, the density of the separation hole 7 at the edge of the circular separation net 1 in the separation zone is smaller than that of the separation hole 7 at the center of the circular separation net 1. The small diameter is to prevent the gas under high pressure from carrying lubricating oil to pass through the separation hole 7 and be discharged to the outside of the compressor; the more separation holes 7 are to ensure that the gas under high pressure can pass through the circular separation net 1 quickly and timely, without affecting the normal use performance of the compressor.

[0036] Specifically, the density of the separation hole 7 in the separation zone gradually decreases in the first direction, wherein the first direction refers to the direction from the center to the edge of the circular separation net 1.

[0037] In the present application, the center of the circular separation net 1 is provided with a cylindrical notch, and the crankshaft 2 is in interference fit with the cylindrical notch; specifically, screws can be used to fix the crankshaft 2 and the circular separation net 1 together to ensure that the circular separation net 1 can rotate synchronously with the crankshaft 2.

[0038] Example 2

[0039] Referring to Figs. 1-3 The application provides a compressor facilitating oil-gas separation, which comprises a shell 10, a compression pump 3, an oil storage cavity 5 and an oil-gas separation assembly arranged in the shell 10, the oil-gas separation assembly is located above the outlet of the compression pump 3, the oil-gas separation assembly comprises a circular separation net 1, the center of the circular separation net 1 is convex to the side of the oil-gas movement direction, and the circular separation net 1 is provided with separation holes 7; and the center of the circular separation net 1 is provided with a crankshaft 2, the crankshaft 2 can drive the circular separation net 1 to rotate.

[0040] When the lubricating oil discharged along with the gas contacts the circular separation net 1, the centrifugal force generated by the rotation of the circular separation net 1 can make the lubricating oil be thrown out, in order to facilitate the smooth return flow of the lubricating oil to the oil storage cavity 5 in the process of being thrown out, the lower surface of the circular separation net 1 is provided with a first oil guide groove, the first oil guide groove extends along the diameter direction of the circular separation net 1, and the first oil guide groove is located between adjacent separation bands, thereby facilitating the return flow of the lubricating oil. Since the lower surface of the circular separation net 1 is an arc-shaped structure extending downward by itself, the lubricating oil will return flow downward along the arc-shaped structure under the action of gravity and centrifugal force, therefore, the first flow guide groove in the application can be located at the edge of the lower surface of the circular separation net 1, or extend from the center to the edge.

[0041] The upper surface of the circular separation net 1 is provided with a second oil guide groove, the second oil guide groove extends along the diameter direction of the circular separation net 1 and is located between adjacent separation bands. Since the upper surface of the circular separation net 1 is an arc-shaped structure extending downward by itself, the lubricating oil will return flow downward along the arc-shaped structure under the action of gravity and centrifugal force, therefore, the second flow guide groove in the application can be located at the edge of the upper surface of the circular separation net 1, or extend from the center to the edge.

[0042] The motor 4 in the application is located above the compression pump 3, the separation chamber 6 is located between the motor 4 and the compression pump 3, the motor 4 and the compression pump 3 are connected through the crankshaft 2, the side wall of the separation chamber 6 is provided with a third oil guide groove, and the third oil guide groove extends vertically. The lubricating oil thrown out from the upper surface and the lower surface of the circular separation net 1 may not directly fall back to the oil storage cavity 5 from the circular separation net 1 under the action of centrifugal force, but is directly thrown on the side wall of the separation chamber 6, at this time, the lubricating oil returns to the oil storage cavity 5 at the bottom of the compressor under the action of gravity, in order to facilitate the return flow of the lubricating oil on the side wall of the separation chamber 6, the third oil guide groove is arranged on the side wall of the separation chamber 6 in the application, and the third oil guide groove extends vertically.

[0043] When the lubricating oil contacts the lower surface of the circular separation net 1, two cases are divided: first, the lubricating oil contacting the lower surface of the circular separation net 1 is thrown out under the centrifugal force, wherein the thrown-out lubricating oil can be thrown to the side wall of the separation chamber 6 along the first oil guide groove in the lower surface of the circular separation net 1, and then returned to the oil storage cavity 5 along the third flow guide groove in the side wall; or the lubricating oil can pass through the separation hole 7 during the falling process, and then be thrown to the side wall of the separation chamber 6 along the second oil guide groove on the upper surface of the circular separation net 1 under the action of gravity and centrifugal force, and then returned to the oil storage cavity 5 along the third flow guide groove in the side wall. The second, the lubricating oil directly passes through the separation hole 7, and is affected by gravity and centrifugal force during the process of passing through the separation hole 7, and is thrown to the side wall of the separation chamber 6 along the second oil guide groove on the upper surface of the circular separation net 1, and then returned to the oil storage cavity 5 along the third flow guide groove in the side wall.

[0044] Embodiment 3

[0045] Please refer to Figs. 1-3 The application provides a compressor facilitating oil-gas separation, which comprises a shell 10, a compression pump 3, a motor 4, an oil storage cavity 5, a separation chamber 6 and an oil-gas separation assembly arranged in the shell 10, wherein the oil storage cavity 5 is located at the bottom of the compression pump 3, the compression pump 3 is located above the oil storage cavity 5, the inlet of the compression pump 3 is connected with a liquid inlet 9, and the other end of the liquid inlet 9 is connected with a liquid distributor 11; the compression pump 3 is connected with the motor 4 through a crankshaft 2, and the separation chamber 6 is arranged between the compression pump 3 and the motor 4; the circular separation net 1 is arranged in the separation chamber 6; a liquid channel is arranged in the oil storage cavity 5, lubricating oil is transmitted to each shaft part through the liquid channel for lubrication, and then returned to the oil storage cavity 5.

[0046] The oil-gas separation assembly comprises the circular separation net 1, the center of the circular separation net 1 is protruded towards the side of the oil-gas movement direction, and the separation hole 7 is arranged in the circular separation net 1; the center of the circular separation net 1 is provided with the crankshaft 2, and the center of the circular separation net 1 is provided with a cylindrical gap in the application, the crankshaft 2 is in interference or clearance fit with the cylindrical gap, and the crankshaft 2 and the circular separation net 1 can be fixed together by screws, so that the circular separation net 1 can rotate synchronously with the crankshaft 2.

[0047] The circular separation net 1 is provided with M separation belts extending along the radial direction, and each separation belt comprises N separation holes 7; M and N are both integers greater than 0.

[0048] The diameters of the separation holes 7 in the separation zone gradually increase in the first direction, wherein the first direction refers to the direction from the center of the circular separation net 1 to the edge. The diameters are set to be different because the outlet of the compression pump 3 is close to the middle position of the circular separation net 1, so when the gas discharged by the compression pump 3 is discharged upward, the gas pressure at the center of the circular separation net 1 is high and the flow rate is fast, and the diameters of the separation holes 7 at the middle position are small, which can reduce the gas flow and prevent a large amount of lubricating oil from being discharged with the high-pressure gas. The small-diameter separation holes 7 ensure that the oil-gas mixture with high pressure and fast flow rate can be fully separated, and at the same time, the large-diameter separation holes 7 at the edge enable the oil-gas mixture with low pressure and slow flow rate to quickly and timely pass through the separation holes 7 to the exhaust port 8 and be discharged. The diameters of the separation holes 7 in the present application are set to be different to ensure that the oil-gas mixture is fully separated and that the gas output by the compression pump 3 does not stay in the compressor for too long, so that the compressor can be timely discharged and the normal use performance of the compressor is not affected.

[0049] The density of the separation holes 7 in the separation zone gradually decreases in the first direction, wherein the first direction refers to the direction from the center of the circular separation net 1 to the edge. The small diameters are to prevent the lubricating oil from being carried by the gas under high pressure to pass through the separation holes 7 and be discharged outside the compressor, and the large number of separation holes 7 is to ensure that the gas under high pressure can quickly and timely pass through the circular separation net 1, so that the normal use performance of the compressor is not affected.

[0050] The lower surface of the circular separation net 1 is provided with a first oil guide groove, which extends along the diameter direction of the circular separation net 1 and is located between adjacent separation zones, facilitating the backflow of lubricating oil. Since the lower surface of the circular separation net 1 is itself an arc-shaped structure extending downward, the lubricating oil will naturally flow downward along the arc-shaped structure under the action of gravity and centrifugal force, so the first flow guide groove in the present application can be located at the edge of the lower surface of the circular separation net 1 or extend from the center to the edge.

[0051] The upper surface of the circular separation net 1 is provided with a second oil guide groove, which extends along the diameter direction of the circular separation net 1 and is located between adjacent separation zones. Since the upper surface of the circular separation net 1 is itself an arc-shaped structure extending downward, the lubricating oil will naturally flow downward along the arc-shaped structure under the action of gravity and centrifugal force, so the second flow guide groove in the present application can be located at the edge of the upper surface of the circular separation net 1 or extend from the center to the edge.

[0052] The side wall of the separation chamber 6 is provided with a third oil guide groove, which extends vertically.

[0053] When the oil-gas mixture passes through the circular separation screen 1, the gas directly passes through the separation holes 7 due to the rotation of the circular separation screen 1. When the lubricating oil contacts the lower surface of the circular separation screen 1, two cases occur. In the first case, the lubricating oil contacting the lower surface of the circular separation screen 1 is thrown out under the centrifugal force, and the thrown-out lubricating oil can be thrown to the side wall of the separation chamber 6 along the first oil guide groove in the lower surface of the circular separation screen 1, and then flows back to the oil storage chamber 5 along the third oil guide groove in the side wall. The thrown-out lubricating oil can also pass through the separation holes 7 during the falling process, and then is thrown to the side wall of the separation chamber 6 along the second oil guide groove in the upper surface of the circular separation screen 1 under the action of the gravity and the centrifugal force, and then flows back to the oil storage chamber 5 along the third oil guide groove in the side wall. In the second case, the lubricating oil directly passes through the separation holes 7, and is thrown to the side wall of the separation chamber 6 along the second oil guide groove in the upper surface of the circular separation screen 1 under the action of the gravity and the centrifugal force during the passing process, and then flows back to the oil storage chamber 5 along the third oil guide groove in the side wall.
