Description

Technical Field

[0001] This utility model relates to the technical field of oil-gas separators, specifically to a spiral guide vane for an oil-gas separator. Background Technology

[0002] An oil-gas separator is a device used to separate lubricating oil from compressed air, typically found in air compressor systems. During air compression, lubricating oil is used to lubricate, cool, and seal internal compressor components, but ultimately it needs to be separated from the compressed air to ensure the output air quality meets application requirements. The main function of an oil-gas separator is to efficiently remove oil droplets carried in compressed air, thereby providing clean compressed air.

[0003] Based on the above, the inventors have discovered the following problems: the current spiral guide vanes have a spiral structure and a smooth surface. This structure is conducive to generating a centrifugal effect in the airflow to achieve oil-gas separation, but the separation effect of this structure is limited and it is not convenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spiral guide vane for an oil-gas separator, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a spiral guide vane for an oil-gas separator to solve the problems mentioned in the background art.

[0006] A spiral guide vane for an oil-gas separator includes a separator assembly. A top cover assembly is detachably connected to the top of the separator assembly. The separator assembly includes an outer barrel and an inner barrel inside the outer barrel. A spiral vane is provided between the outer barrel and the inner barrel. The spiral vane is fixedly connected to the outer barrel and the inner barrel. A plurality of guide vanes are fixedly installed at the bottom of the spiral vane. The guide vanes have a spiral structure. The top of the guide vane is close to the inner barrel, and the bottom of the guide vane is close to the outer barrel.

[0007] By adopting the above technical solution, a top cover assembly is detachably connected to the top of the separation tank assembly, which facilitates sealing the top of the separation tank assembly, providing sealing protection, and facilitating the disassembly and replacement of the fine filter element. The arrangement of the outer and inner tanks facilitates the formation of an oil-gas separation channel inside the outer tank. Gas undergoes centrifugal separation through the spiral blades between the outer and inner tanks. After separation, the gas enters the inner tank, while the separated oil flows downwards and collects at the bottom of the inner side of the outer tank. The spiral blades facilitate the guidance of the airflow spiral motion, causing the oil mist droplets in the airflow to be separated into oil and gas by centrifugal force. The guide vanes further guide the airflow, causing it to rotate further along the spiral path on the basis of spiral flow, thereby optimizing the airflow distribution and enhancing the separation effect.

[0008] Furthermore, the outer barrel is provided with an air inlet and an air outlet on its top outer side, and the air inlet is connected to the outer barrel.

[0009] By adopting the above technical solution and setting the air inlet, it is easy to connect to the external air supply pipeline, and convenient to introduce the gas to be separated into the outer tank.

[0010] Furthermore, the air outlet is connected to the inner barrel, and a fixing ring is fixedly installed on the inner side of the top of the inner barrel.

[0011] By adopting the above technical solution and setting the gas outlet interface, it is easy to connect to the external pipeline and convenient to discharge the gas after oil-gas separation.

[0012] Furthermore, a fine filter element is detachably connected inside the fixing ring, and the fine filter element is located at the bottom of the air outlet.

[0013] By adopting the above technical solution and setting the fine filter element, it is convenient to further filter the gas after centrifugal separation by the spiral blades, and prevent fine oil mist particles from being discharged from the gas outlet.

[0014] Furthermore, an oil outlet is provided on one side of the middle of the outer barrel, and a sewage outlet is provided at the middle of the bottom of the outer barrel.

[0015] By adopting the above technical solution and setting the sewage outlet, it is easy to connect to the external pipeline and conveniently discharge the impurities settled at the bottom of the inner side of the outer tank.

[0016] Furthermore, an oil outlet pipe is fixedly installed on one side of the oil outlet interface, and one end of the oil outlet pipe extends to the bottom of the inner side of the outer barrel.

[0017] By adopting the above technical solution, the oil outlet pipe is designed to facilitate connection of the oil outlet interface to the external oil return equipment, making it convenient for the oil outlet pipe to extract and recycle the oil collected at the bottom of the inner side of the outer barrel.

[0018] Furthermore, the top cover assembly includes a cover body, and a sealing groove is provided at the bottom of the cover body.

[0019] By adopting the above technical solution and setting the sealing groove, the sealing performance between the lid and the inner and outer barrels is enhanced, thus preventing leakage.

[0020] Furthermore, the surfaces of the spiral blades and guide vanes are provided with an oleophobic coating, the oleophobic coating being made of polytetrafluoroethylene.

[0021] By adopting the above technical solution and setting the oleophobic coating, polytetrafluoroethylene material has excellent hydrophobic and oleophobic properties, and is chemically stable, which makes it easy to reduce oil droplet adhesion and promote oil droplet sliding.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The top cover assembly is detachably connected to the top of the separation tank assembly, facilitating the sealing of the top of the separation tank assembly, providing sealing protection, and making it easy to disassemble and replace the fine filter element. The outer and inner tanks facilitate the formation of an oil-gas separation channel inside the outer tank. Gas undergoes centrifugal separation through the spiral blades between the outer and inner tanks. After separation, the gas enters the inner tank, while the separated oil flows downwards and collects at the bottom of the inner side of the outer tank. The spiral blades facilitate guiding the airflow in a spiral motion, causing the oil mist droplets in the airflow to be separated into oil and gas by centrifugal force. The guide vanes further guide the airflow, causing it to rotate further along the spiral path on the basis of spiral flow, thus optimizing the airflow distribution and enhancing the separation effect.

The top cover assembly 2 facilitates sealing the top of the separator assembly 1, providing a sealed protection and facilitating the removal and replacement of the fine filter element 3. The separator assembly 1 includes an outer barrel 11 and an inner barrel 12 inside the outer barrel 11. The arrangement of the outer barrel 11 and the inner barrel 12 facilitates the formation of an oil-gas separation channel inside the outer barrel 11. Gas undergoes centrifugal separation via spiral vanes 14 between the outer barrel 11 and the inner barrel 12. The separated gas enters the inner barrel 12, while the separated oil flows downwards and collects in the outer barrel 11. 1. A spiral blade 14 is provided between the outer barrel 11 and the inner barrel 12 on the inner bottom. The spiral blade 14 facilitates the spiral movement of the airflow, so that the oil mist droplets in the airflow are separated by centrifugal force. The spiral blade 14 is fixedly connected to the outer barrel 11 and the inner barrel 12. Several guide blades 110 are fixedly installed at the bottom of the spiral blade 14. The guide blades 110 have a spiral structure. The top of the guide blades 110 is close to the inner barrel 12 and the bottom of the guide blades 110 is close to the outer barrel 11. The guide blades 110 facilitate further guidance of the airflow, so that the airflow rotates further along the spiral path on the basis of spiral flow, thereby optimizing the airflow distribution and enhancing the separation effect.

[0031] The outer barrel 11 has an air inlet 16 and an air outlet 15 on its top outer side. The air inlet 16 is connected to the outer barrel 11. The air inlet 16 facilitates connection to the external gas pipeline, making it easy to introduce the gas to be separated into the outer barrel 11.

[0032] The air outlet 15 is connected to the inner barrel 12, and a fixing ring 13 is fixedly installed on the inner side of the top of the inner barrel 12. The air outlet 15 facilitates connection to external pipelines and allows the gas after oil-gas separation to be discharged.

[0033] The fixed ring 13 is detachably connected to a fine filter element 3. The fine filter element 3 is set at the bottom of the air outlet 15. The fine filter element 3 facilitates further filtration of the gas after centrifugal separation by the spiral blades 14, preventing fine oil mist particles from being discharged from the air outlet 15.

[0034] The outer barrel 11 has an oil outlet 17 on one side of the middle section, and a drain outlet 18 is provided at the middle of the bottom of the outer barrel 11. The drain outlet 18 facilitates connection to external pipelines and makes it easy to discharge impurities that have settled at the bottom of the inner side of the outer barrel 11.

[0035] An oil outlet pipe 19 is fixedly installed on one side of the oil outlet interface 17. One end of the oil outlet pipe 19 extends to the bottom of the inner side of the outer barrel 11. The oil outlet pipe 19 facilitates the connection of the oil outlet interface 17 to the external oil return equipment, and makes it convenient for the oil outlet pipe 19 to extract and recycle the oil collected at the bottom of the inner side of the outer barrel 11.

[0036] The top cover assembly 2 includes a cover body 21, and a sealing groove 22 is provided at the bottom of the cover body 21. The sealing groove 22 is provided to enhance the sealing between the cover body 21 and the inner barrel 12 and the outer barrel 11, and to prevent leakage.

[0037] Among them, the spiral blade 14 and the guide blade 110 are provided with an oleophobic coating. The oleophobic coating is made of polytetrafluoroethylene. Through the setting of the oleophobic coating, polytetrafluoroethylene has excellent hydrophobic and oleophobic properties and stable chemical properties, which makes it easy to reduce the adhesion of oil droplets and promote the sliding of oil droplets.

[0038] Specifically, the working principle of the spiral guide vanes in this type of oil-gas separator is as follows: During use, the sealing groove 22 enhances the sealing between the cover 21 and the inner and outer barrels 12, preventing leakage. The air inlet 16 facilitates connection to an external gas pipeline, allowing the gas to be separated to be introduced into the outer barrel 11. The outer barrel 11 and inner barrel 12 form an oil-gas separation channel within the outer barrel 11. The gas undergoes centrifugal separation via the spiral vanes 14 between the outer and inner barrels 11. After separation, the gas enters the inner barrel 12, while the separated oil collects downwards to the bottom of the inner side of the outer barrel 11. The spiral vanes 14 guide the airflow in a spiral motion, causing the oil mist droplets in the airflow to be separated by centrifugal force. The guide vanes 110 further guide the airflow, causing it to rotate further along the spiral path on top of the spiral flow, thus optimizing the gas flow. The flow distribution enhances the separation effect. Through the setting of the oleophobic coating, the polytetrafluoroethylene material has excellent hydrophobic and oleophobic properties and stable chemical properties, which can reduce the adhesion of oil droplets and promote the sliding of oil droplets. Through the setting of the fine filter element 3, it is easy to further filter the gas after centrifugation by the spiral blades 14, and prevent fine oil mist particles from being discharged from the gas outlet 15. Through the setting of the gas outlet 15, it is easy to connect to the external pipeline to facilitate the discharge of the gas after oil-gas separation. Through the setting of the drain port 18, it is easy to connect to the external pipeline to facilitate the discharge of impurities settled at the bottom of the inner side of the outer barrel 11. Through the setting of the oil outlet pipe 19, it is easy to connect the oil outlet port 17 to the external oil return equipment, so that the oil collected at the bottom of the inner side of the outer barrel 11 can be extracted and recycled. The top cover assembly 2 is detachably connected to the top of the separation barrel assembly 1, which facilitates the sealing of the top of the separation barrel assembly 1, provides sealing protection, and facilitates the disassembly and replacement of the fine filter element 3.
