[0002] The oil-liquid separator for centrifugal compressor speed-increasing gearbox is mainly used to separate lubricating oil and gas to ensure the normal operation of the compressor and speed-increasing gearbox. Because the lubricating oil mixed in the gas can easily affect the performance and stability of the compressor, the compressor and speed-increasing gearbox need to use the oil-liquid separator for centrifugal compressor speed-increasing gearbox to discharge the air during operation. When the lubricating oil needs to be recycled and reused, the equipment can also be used to separate the lubricating oil, thereby reducing the consumption of lubricating oil and extending the service life of the equipment.

[0003] In the prior art, when the oil-liquid separator for the centrifugal compressor speed increasing gearbox separates the lubricating oil and the air, the centrifugal separation equipment is mostly used to generate centrifugal force, so that the lubricating oil with a higher density will move in the direction of the centrifugal force, that is, it will be deposited on the inner wall of the separator, while the air with a lower density will move toward the center and eventually be discharged from the separator. When the lubricating oil is dispersed on the inner wall of the separator under the action of the centrifugal force, the lubricating oil flows down along the inner wall of the separator and accumulates at the bottom of the separator, the lubricating oil is dispersed under the action of the centrifugal force, so that its volume is smaller, the accumulation speed is slower, and the efficiency is lower, thereby making the processing efficiency of the centrifugal separation equipment lower, and because most of the equipment does not have a cleaning mechanism, the lubricating oil is easy to adhere to the inner wall of the separator, resulting in a waste of resources. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when an oil-liquid separator for a centrifugal compressor speed-increasing gearbox separates lubricating oil and air, centrifugal force is mostly generated through a centrifugal separation device, so that the lubricating oil with a larger density moves in the direction of the centrifugal force, that is, it is deposited on the inner wall of the separator, while the air with a smaller density moves toward the center and is finally discharged from the separator. When the lubricating oil is dispersed on the inner wall of the separator under the action of centrifugal force, the lubricating oil flows down along the inner wall of the separator and accumulates at the bottom of the separator, the lubricating oil is dispersed under the action of centrifugal force, so that its volume is smaller, the accumulation speed is slower, and the efficiency is lower, thereby making the processing efficiency of the centrifugal separation device lower.

[0042] When the present invention is in use, a special pipeline is connected to the connecting pipe 2. When the centrifugal compressor speed increasing gearbox generates a gas mixture containing lubricating oil during operation, the gas mixture will enter the shell 1 through the connecting pipe 2. When entering the shell 1, it will first pass through the coarse filter layer 4 in the circular shell 3. At this time, the coarse filter layer 4 will remove large particle impurities and part of the lubricating oil in the gas mixture. After passing through the coarse filter layer 4, it will pass through the fine filter layer 5 to further remove tiny oil droplets and impurities in the gas.

[0043] After passing through the circular shell 3, it will fall into the centrifugal shell 8. At this time, the motor 6 drives the rotating shaft 7 and the centrifugal shell 8 to rotate, so that the rotation of the centrifugal shell 8 generates centrifugal force. At this time, the lubricating oil with higher density will move in the direction of the centrifugal force, thereby being deposited on the inner wall of the centrifugal shell 8, and the air with lower density will move toward the center until it is discharged from the centrifugal shell 8 and the housing 1. When the centrifugal shell 8 rotates, a group of scrapers 10 are fixed to the bottom end of the outer wall of the cover plate 9, so that the centrifugal shell 8 rotates, and the scraper 10 remains stationary, so that the lubricating oil deposited on the inner wall of the centrifugal shell 8 will encounter the scraper 10 as the centrifugal shell 8 rotates, thereby being deposited on the scraper 10, so that more and more lubricating oil is deposited together, so that the deposited lubricating oil is easier to slide down under the influence of gravity, thereby increasing the accumulation speed of the lubricating oil, and improving the efficiency of sliding separation, and the scraper 10 also cleans the lubricating oil deposited on the inner wall of the centrifugal shell 8, so that the lubricating oil is not easily wasted.

[0044] When the centrifugal shell 8 rotates, the rotation of the centrifugal shell 8 will drive the first annular rack 12 to rotate. Since a group of first gears 13 are meshed with the first annular rack 12, the rotation of the first annular rack 12 will drive the first gear 13 to rotate, and the first gear 13 drives the first reciprocating rod 15 to rotate. When the first reciprocating rod 15 rotates, the cleaning plate 14 will reciprocate up and down under the rotation of the first reciprocating rod 15, thereby cleaning the lubricating oil deposited on the scraper 10, or accelerating the lubricating oil to slide down during the up and down movement of the cleaning plate 14, thereby further improving the separation efficiency and effect of the lubricating oil, and the up and down movement of the cleaning plate 14 will make it difficult for the lubricating oil to adhere to the scraper 10, thereby reducing the waste of lubricating oil. And when the cleaning plate 14 moves up and down, a group of inclined holes 16 are opened at the top of the outer wall of the cleaning plate 14; the opening of one end of the outer wall of the inclined hole 16 is located at the top of the outer wall of the cleaning plate 14, and the opening of the other end of the outer wall of the inclined hole 16 is located at the outer side wall of the cleaning plate 14, so that when the cleaning plate 14 moves down, the lubricating oil will be pushed downward by the cleaning plate 14, thereby accelerating the separation efficiency of the lubricating oil, and when the cleaning plate 14 moves up, the lubricating oil will gradually move to the collecting groove 17 during the upward movement of the cleaning plate 14, and then slide from the collecting groove 17 through the inclined holes 16 to the outside of the cleaning plate 14, and then slide to the bottom of the cleaning plate 14 until the cleaning plate 14 moves down and accelerates its separation efficiency, so that the cleaning plate 14 is moved up and down through its internal structure, which not only does not affect the separation efficiency of the lubricating oil, but also accelerates its separation efficiency. A group of arc plates 18 are provided between a group of cleaning plates 14, so that when the cleaning plates 14 move up and down, the arc plates 18 will be driven to move up and down, so that the cleaning plates 14 cooperate with the arc plates 18 to drive the lubricating oil to move up and down, so that the lubricating oil accumulates, and then through the rotation of the centrifugal shell 8, the scraper 10 accumulates the lubricating oil again, thereby further accelerating the accumulation efficiency of the lubricating oil, so that the device can more efficiently accelerate the accumulation and separation efficiency of the lubricating oil, and when the lubricating oil slides out of the inclined hole 16, it will also be driven by the arc plate 18, so that the separation efficiency of the lubricating oil is better.

[0045] When the arc plate 18 moves downward and encounters the lubricating oil, the lubricating oil will flow into the connecting groove 21 through the oblique groove 20 on the arc plate 18, and then flow into the filter shell 19 from the connecting groove 21. When the qualified lubricating oil flows into the filter shell 19, it will flow out through the filter hole 22 on the filter shell 19, while the unqualified lubricating oil or impurities will be left in the filter shell 19, so that the device can further reduce the impurities contained in the separated lubricating oil, thereby making the quality of the separated lubricating oil higher, thereby reducing the steps of reprocessing the separated lubricating oil, and making the separation operation of the lubricating oil more efficient.

[0046] When the cleaning plate 14 drives the arc plate 18 and the filter shell 19 to move downward, the filter shell 19 drives the second reciprocating rod 24 and the second gear 25 to move downward. Since the second gear 25 is meshed with the second rack 23 and the second gear 25 can only move up and down, and the second gear 25 remains fixed, the second gear 25 will rotate when moving up and down, thereby driving the second reciprocating rod 24 to rotate, and the rotation of the second reciprocating rod 24 drives the anti-blocking plate 26 to reciprocate, thereby cleaning the filter hole 22 and preventing the filter hole 22 from being blocked.

[0047] The back and forth movement of the anti-blocking plate 26 also accelerates the sliding separation efficiency of the lubricating oil, and the filter hole 22 is not blocked, which makes the lubricating oil not easily wasted, thereby reducing costs. When the centrifugal shell 8 rotates, the centrifugal shell 8 drives the discharge pipe 27, the rotating rod 29 and the third gear 30 to rotate around the center of the centrifugal shell 8. Because the third arc-shaped rack 31 is meshed with the third gear 30 and the third arc-shaped rack 31 remains in a fixed state, the third gear 30 will rotate when the inner side wall of the third arc-shaped rack 31 moves, so that the third gear 30 drives the rotating rod 29 to rotate, and the rotating rod 29 drives the threaded blades 32 to rotate. When the centrifugal shell 8 rotates and the lubricating oil slides to the discharge pipe 27, the lubricating oil will move into the discharge pipe 27 through the first through groove 28, and then through the rotation of the threaded blades 32, the lubricating oil slides quickly, so that the device accelerates the separation efficiency of the lubricating oil through the threaded blades 32, so that the separation efficiency and effect of the device are better.

[0048] The outer wall of the centrifugal shell 8 is fixedly connected with the separation shell 33 and the outer wall of the centrifugal shell 8 is provided with a group of circular holes 34, so that when the lubricating oil slides into the centrifugal shell 8, the lubricating oil will move to the inner wall of the centrifugal shell 8 by centrifugal force, and then move to the separation shell 33 through the circular holes 34, so that the separation shell 33 and the centrifugal shell 8 can separate the lubricating oil at the same time, so that the device can separate more lubricating oil at the same time, and through the filtering of the circular holes 34, the device can also separate and screen lubricating oil of different qualities. When the lubricating oil flows out through the circular pipe 35 and the discharge pipe 27, it will move to the annular storage shell 37, and then move from the delivery pipe 38 to other connecting devices, completing the separation and reuse of the lubricating oil.

[0049] When the centrifugal shell 8 rotates, the rotation of the centrifugal shell 8 drives the circular rod 39 to rotate, and the rotation of the circular rod 39 drives a group of guide blades 40 to rotate. The rotation of the guide blades 40 guides the airflow, so that the air is more easily gathered toward the center, so that the air and the lubricating oil can be separated more efficiently, and the separation quality of the lubricating oil is better. In addition, an arc block 41 is fixedly connected to the bottom end of the inner wall of the separation shell 33, so that when the separation shell 33 separates the lubricating oil, the lubricating oil slides to the arc block 41 and is blocked, so that the lubricating oil slides along the surface of the arc block 41 to the circular tube 35, and then moves from the circular tube 35 to the annular storage shell 37, thereby further improving the separation efficiency of the lubricating oil in the separation shell 33.
