Description

Technical Field

[0001] This utility model relates to the field of oil-gas separator technology, and in particular to an oil-gas separator for an air compressor. Background Technology

[0002] In industrial production, air compressors, as core equipment for providing compressed air, are widely used in various fields such as machinery manufacturing, chemical industry, and food processing. The compressed air produced by an air compressor typically contains impurities such as lubricating oil. As a key component of the air compressor, the oil-gas separator separates the oil from the gas in the compressed air, ensuring that the output compressed air meets the cleanliness requirements of different production processes, while also recovering lubricating oil and improving resource utilization.

[0003] Currently, most commercially available air compressor oil-gas separators combine filter cartridge filtration with centrifugal separation. Filter cartridge filtration uses filter materials with specific pore sizes to intercept oil mist particles, while centrifugal separation utilizes the centrifugal force generated by the high-speed rotation of the gas to separate oil droplets from the gas. When oil-containing gas enters the separator, larger oil droplets are first thrown against the inner wall of the separator and converge and flow down under the action of centrifugal force; subsequently, the gas that has undergone preliminary separation passes through the filter cartridge for fine filtration, further removing tiny oil mist particles.

[0004] However, existing air compressor oil-gas separators have a significant problem during long-term operation. Due to the lack of an effective internal wall cleaning mechanism, as oily gas continuously flows through the separator, oil and impurities accumulate on the inner wall. This not only affects the gas flow path and increases airflow resistance, leading to a gradual decrease in separation efficiency, but the accumulated oil also breeds bacteria, corrodes the equipment, and shortens the service life of the oil-gas separator. If not cleaned in time, it can also cause secondary pollution, causing the separated clean gas to be mixed with impurities again, making it difficult to meet the increasingly stringent requirements for compressed air quality in industrial production. Therefore, an oil-gas separator for air compressors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an oil-gas separator for air compressors, aiming to improve the problem that if the inner wall of the oil-gas separator cannot be cleaned, oil stains and impurities will continuously accumulate on the inner wall.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An oil-gas separator for an air compressor includes a fixed ring, a support column fixedly connected to the bottom of the fixed ring, a conversion vessel fixedly connected to the inner wall of the fixed ring, a gas discharge pipe fixedly connected to the top of the conversion vessel, a cyclone separator fixedly connected inside the conversion vessel, an inlet pipe fixedly connected to the outer wall of the conversion vessel, and a cleaning component installed inside the conversion vessel.

[0008] The cleaning assembly includes a nozzle, the outer wall of which is fixedly connected to the inside of the conversion vessel. A liquid return pipe is fixedly connected to the top of the conversion vessel. A first valve and a second valve are fixedly connected inside the liquid return pipe. A first connecting pipe is fixedly connected to the bottom of the conversion vessel. An oil storage tank is fixedly connected to one end of the first connecting pipe. A third valve is fixedly connected to the bottom of the oil storage tank.

[0009] As a further description of the above technical solution:

[0010] The inner wall of the conversion vessel is provided with a filter column, and a connecting block is fixedly connected to the outer wall of the filter column.

[0011] As a further description of the above technical solution:

[0012] The bottom of the conversion vessel is fixedly connected to a hollow groove ring, and the connecting block is slidably connected inside the hollow groove ring.

[0013] As a further description of the above technical solution:

[0014] A hollow column is fixedly connected to the bottom of the hollow groove ring, and a limit ring is fixedly connected to the inner wall of the hollow column.

[0015] As a further description of the above technical solution:

[0016] The inner wall of the limiting ring is slidably connected to a sliding column, and the inner wall of the sliding column is rotatably connected to a hanging ring.

[0017] As a further description of the above technical solution:

[0018] The outer wall of the sliding column is slidably connected to the inside of the slotted ring, and the outer wall of the sliding column is slidably connected to the inside of the connecting block.

[0019] As a further description of the above technical solution:

[0020] A spring is provided on the outer wall of the sliding column. One end of the spring is fixedly connected to the outer wall of the sliding column, and the other end of the spring is fixedly connected to the top of the limiting ring.

[0021] As a further description of the above technical solution:

[0022] The sliding column sidewall is slidably connected to the outer wall of the filter column, and the hanging ring sidewall is slidably connected to the outer wall of the filter column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the second valve is first closed, then the water source is connected to the nozzle, and then the nozzle is used to rotate the water inside the conversion vessel. The cleaning solution flows through the first connecting pipe to the inside of the oil storage tank, and then the dirty water is discharged through the third valve, thus achieving the effect of cleaning the inner wall of the conversion vessel. This solves the problem that if the inner wall of the oil-gas separator cannot be cleaned, oil stains and impurities will accumulate on the inner wall, improving the practicality of the oil-gas separator.

[0025] 2. In this utility model, pulling the hanging ring drives the sliding column to move, and then the outer wall of the sliding column disengages from the inside of the connecting block and the empty groove ring. Then the filter column can be rotated to drive the connecting block to disengage from the inside of the empty groove ring, achieving the effect of quick disassembly of the filter column. This solves the problem that the filter cover does not have a quick disassembly function and requires a lot of time and effort to replace or clean, thus improving the convenience of the oil-gas separator used in air compressors.

[0035] The cleaning assembly includes a nozzle 21, the outer wall of which is fixedly connected to the inside of the conversion vessel 3. A liquid return pipe 6 is fixedly connected to the top of the conversion vessel 3. A first valve 7 and a second valve 8 are fixedly connected inside the liquid return pipe 6.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The inner wall of the converter 3 is provided with a filter column 13, and a connecting block 20 is fixedly connected to the outer wall of the filter column 13. A slotted ring 14 is fixedly connected to the bottom of the converter 3. The connecting block 20 is slidably connected inside the slotted ring 14. A hollow column 15 is fixedly connected to the bottom of the slotted ring 14. A limit ring 16 is fixedly connected to the inner wall of the hollow column 15. A sliding column 18 is slidably connected to the inner wall of the limit ring 16. A hanging ring 17 is rotatably connected to the inner wall of the sliding column 18. The outer wall of the sliding column 18 is slidably connected to the inside of the slotted ring 14. The outer wall of the sliding column 18 is slidably connected to the inside of the connecting block 20. A spring 19 is provided on the outer wall of the sliding column 18. One end of the spring 19 is fixedly connected to the outer wall of the sliding column 18. The other end of the spring 19 is fixedly connected to the top of the limit ring 16. The side wall of the sliding column 18 is slidably connected to the outer wall of the filter column 13. The side wall of the hanging ring 17 is slidably connected to the outer wall of the filter column 13.

[0037] Working principle: The compressed oil-gas mixture enters the conversion vessel 3 through the inlet pipe 4. The mixture is first guided to the internal cyclone separator 9. Under the centrifugal force of the cyclone separator 9, most of the oil droplets and larger particulate impurities are thrown to the vessel wall and flow downward along the wall. The separated liquid oil gathers at the bottom of the conversion vessel 3 and flows into the oil storage tank 10 below through the first connecting pipe 12. During normal operation, the third valve 11 can be opened periodically to discharge the collected lubricating oil back to the system or replace it. The gas after cyclone separation still contains fine oil mist that flows upward. Through the filter column 13 set on the inner wall of the conversion vessel 3, most of the remaining tiny oil mist particles can be adsorbed and intercepted. The purified compressed air is discharged from the gas discharge pipe 5 for subsequent use.

[0038] Close the second valve 8 on the liquid return pipe 6, connect the cleaning water source (such as solvent or cleaning fluid) to the nozzle 21, and the cleaning fluid is sprayed out from the nozzle 21 to flush the inner wall of the conversion vessel 3 and the surface of the cyclone separator 9. The nozzle 21 is designed to have a rotating or wide-angle spray function to cover a larger area. The dirty water / waste liquid generated during flushing flows down the vessel wall to the bottom and flows into the oil storage tank 10 through the first connecting pipe 12. Open the third valve 11 to discharge the dirty water / waste liquid in the oil storage tank 10 from the system. This function effectively solves the problem of oil accumulation on the inner wall and improves the stability and practicality of the equipment in long-term operation.

[0039] Pulling the hanging ring 17 causes the sliding column 18 to move downward against the elastic force of the spring 19. The sliding column 18 slides downward, causing its outer wall to disengage from the mating groove of the connecting block 20 and the empty groove ring 14. At this time, the filter column 13 and its connected connecting block 20 are no longer locked in the empty groove ring 14 by the sliding column 18. The filter column 13 can be rotated directly and taken out upward to complete the disassembly.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
