Description

Technical Field

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

[0002] Oil-gas separators are an essential component of air compressors. When an air compressor is working, the air compressed by the compressor is under high temperature and pressure, which inevitably causes some of the lubricating oil inside the machine to vaporize into oil vapor and small oil droplets. These oil droplets enter the exhaust pipe along with the compressed air. If the oil droplets enter the cooler that cools the gas, the cooling effect of the cooler will be reduced. Therefore, an oil separator must be installed between the compressor and the cooler to separate the lubricating oil from the refrigeration vapor.

[0003] In the prior art, patent document with publication number (CN218740911U) mentions a compressor oil-gas separation device, including a housing, an oil separator core body disposed inside the upper end of the housing, and two rotating rods disposed on the inner wall of the upper end of the housing. An oil scraping ring is fitted onto the bottom surface of the oil separator core body, and connecting blocks are disposed on both sides of the oil scraping ring. The bottom end of each rotating rod is threadedly connected to the upper part of the corresponding connecting block, and a gear set is disposed between the two rotating rods. This prior art, with its housing, connecting pipe, flow sensor, oil separator core body, rotating rods, oil separator ring, gear set, motor, and rotating shaft, can detect the oil adhesion on the surface of the oil separator core body based on the gas discharge during oil-gas separation. Based on the detection structure, it can determine whether to scrape the oil from the oil separator core body using the oil scraping ring, ensuring efficient oil-gas separation while avoiding damage to the surface of the oil separator core body.

[0004] However, in the aforementioned existing technology, the oil separator core is fixed inside the outer casing, resulting in slower oil-gas separation and lower working efficiency. Utility Model Content

[0020] This utility model provides an oil-gas separation structure for a compressor, including a housing 1, a separation mechanism, a connecting pipe 2, an oil outlet pipe 3, and an air inlet pipe 4. The separation mechanism includes a separator 5, a mounting ring 6, a retaining ring 7, a fixing ring 8, four connecting rods 9, several ball bearings 10, and four scraping components. The scraping components include several pushing modules and scrapers 11. The pushing modules include a round rod 12, a sleeve 13, a locking block 14, and a spring 15. The aforementioned solution solves the problem in the prior art where the oil separator core is fixed inside the outer casing, resulting in slow oil-gas separation and low working efficiency.

[0021] In this specific embodiment, the separator 5 is disposed inside the housing 1.

The retaining ring 7 is fixedly connected to the separator 5 and located below the separator 5. The fixing ring 8 is rotatably connected to the retaining ring 7 and covers the outside of the retaining ring 7. One end of each of the four connecting rods 9 is fixedly connected to the fixing ring 8, and the other end of each of the four connecting rods 9 is fixedly connected to the housing 1 and is respectively disposed within the housing 1. Outside the fixed ring 8, the four scraping components are respectively positioned above the corresponding connecting rods 9. A motor 16 is located below the housing 1. The output end of the motor 16 is fixedly connected to the separator 5. The mounting ring 6 fixes the separator 5 inside the housing 1. The fixed ring 8 supports the retaining ring 7. Oil and gas are injected into the housing 1. The separator 5 filters the oil. The motor 16 drives the separator 5 to rotate. The scraping components scrape the oil. When the gas flow rate meets the requirements, the motor 16 stops working.

[0022] Among them, a number of the ball bearings 10 are rotatably connected to the fixed ring 8 and are evenly arranged between the retaining ring 7 and the fixed ring 8. When the separator 5 rotates, the ball bearings 10 rotate accordingly, reducing the friction between the fixed ring 8 and the retaining ring 7.

[0023] Secondly, the scraper 11 is disposed on one side of the separator 5 and contacts the separator 5, and a plurality of the pushing modules are disposed on one side of the scraper 11.

The locking block 14 is fixedly connected to the round rod 12 and located on one side of the round rod 12. One end of the sleeve 13 is slidably connected to the round rod 12, and the other end of the sleeve 13 is fixedly connected to the housing 1 and covers the surface of the round rod 12. The spring 15 is disposed inside the sleeve 13 and located on one side of the locking block 14. The locking block 14 secures the round rod 12 inside the sleeve 13. The spring 15 pushes the round rod 12, causing the scraper 11 to adhere tightly to the separator 5.

[0025] In addition, the connecting pipe 2 is fixedly connected to the housing 1 and located above the housing 1, the oil outlet pipe 3 is fixedly connected to the housing 1 and located below the housing 1, and the air inlet pipe 4 is fixedly connected to the housing 1 and located on one side of the housing 1.

The gas is removed through the connecting pipe 2, and the oil is discharged through the oil outlet pipe 3.

[0026] When using this utility model, oil and gas are added into the interior of the housing 1 through the air inlet pipe 4 and filtered. The gas is then removed through the connecting pipe 2, and the oil is discharged through the oil outlet pipe 3. The separator 5 filters the oil. The motor 16 drives the separator 5 to rotate. The spring 15 pushes the round rod 12, causing the scraper 11 to stick tightly to the separator 5. When the gas flow rate meets the requirements, the motor 16 stops working.

[0027] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application.
