Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an oil-gas separation barrel for a compressor with a new structure. Background Art

[0002] The oil-gas separator is a crucial component in a compressor, primarily responsible for separating oil and gas and storing lubricating oil. When the compressed oil-gas mixture enters the separator, a rotation or filtration process within the separator allows the majority of the lubricating oil to be effectively separated, ensuring proper compressor operation and lubricating oil recycling. The separator also stores ample lubricating oil, preventing hot, freshly separated oil from immediately recirculating, helping to lower exhaust temperatures and improve equipment efficiency.

[0003] The oil-gas separator barrels currently used in compressors require regular maintenance of the oil separator core. During maintenance, the pipe of the minimum pressure valve, the oil return pipe next to it, and the vent pipe must all be removed before the lid can be removed to access the oil separator core, which is a rather cumbersome operation.

[0004] An existing publicly available technical solution, with publication number CN213144749U, discloses an air compressor oil-gas separation barrel. It comprises a barrel body and a lid. An oil separator core and a separation barrel are fixedly mounted within the barrel body, sequentially arranged from top to bottom. An oil inlet pipe is welded to the barrel body's outer wall and connected thereto. The oil inlet pipe is tangent to the barrel body's inner wall, and its terminal end is positioned opposite the lower end of the separation barrel. A minimum pressure valve is fixedly mounted on the barrel body's outer wall and located at the upper end of the oil separator core. A fixing seat is welded to the barrel body's outer wall, secured with screw A. This facilitates cleaning or replacement of the oil separator core, reduces labor intensity, lowers the oil molecule content in the output gas, and is simple to operate.

[0005] When the above technical solution is actually implemented, the minimum pressure valve is set at the upper end of the oil separator core. The oil separator core can be taken out by directly opening the barrel cover. However, in order to allow the gas to be discharged by the minimum pressure valve, the minimum pressure valve needs to be placed higher than the oil separator core. The minimum pressure valve is installed on the barrel body, which results in the top of the oil separator core needing to be much lower than the barrel body. When taking the oil separator core, the hand needs to reach into the barrel body to take out the oil separator core, which is inconvenient to operate. Summary of the Invention

[0006] The purpose of this utility model is to provide a new structure oil and gas separation barrel for a compressor, which can push the oil separation core bracket upward through a telescopic spring when the upper end cover is opened, thereby facilitating the user to remove the oil separation core body, thereby solving the problems raised in the above-mentioned background technology.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4A novel structure of an oil-gas separation barrel for a compressor includes an oil-gas separation barrel body 1, a lower end cover 13 fixedly provided on the top of the oil-gas separation barrel body 1, an upper end cover 2 rotatably installed on the top of the lower end cover 13 via a hinge, and an air circulation groove 3 is provided inside the upper end cover 2, a minimum pressure valve 15 is installed on one side of the oil-gas separation barrel body 1, and an oil separation core mechanism 4 is installed inside the oil-gas separation barrel body 1;

[0028] The oil separator core mechanism 4 includes an oil separator core body 401 installed inside the oil-gas separation barrel body 1, and an oil return pipe 5 is passed through the interior of the oil separator core body 401, and the end of the oil return pipe 5 is connected to a ferrule right-angle terminal 6, and an oil separator core bracket 402 is fixedly installed around the oil separator core body 401, and a telescopic component is installed below the oil separator core bracket 402, and a support plate 403 is fixedly installed below the telescopic component.

[0029] The oil separation core body 401 passes through the interior of the support plate 403, and the support plate 403 is fixed inside the oil and gas separation barrel 1. The telescopic assembly includes two groups of parallel baffles 404, and a telescopic spring 406 is installed between the two groups of baffles 404. A telescopic sleeve 405 is passed through the interior of the telescopic spring 406, and a telescopic rod 407 is passed through the interior of the telescopic sleeve 405. A sealing cover plate 11 is provided between the oil separation core bracket 402 and the lower end cover 13, and a sealing ring 12 is provided between the sealing cover plate 11 and the lower end cover 13. An air return port 14 is also provided inside the sealing cover plate 11.

[0030] By adopting the above technical solution, during installation, the oil separator core bracket 402 is installed inside the sealing cover plate 11 and is set above the support plate 403. At this time, under the elastic support of the telescopic spring 406, the oil separator core bracket 402 is higher than the lower end cover 13, and then the upper end cover 2 is covered to close the upper end cover 2 and the lower end cover 13. Under the pressure of the upper end cover 2, the oil separator core bracket 402 moves downward and presses the telescopic spring 406. After the telescopic spring 406 is compressed, the oil separator core bracket 402 can be flush with the lower end cover 13 and enter the oil well. After the oil and gas mixture in the gas separation barrel 1 is filtered, the gas moves upward from the center position of the oil separator core body 401 to the air circulation groove 3, and reaches the air inlet end of the minimum pressure valve 15 along the air circulation groove 3, and is discharged outward through the minimum pressure valve 15. The upper end cover 2 is fixed to the lower end cover 13 by bolts. After unscrewing the bolts on the upper end cover 2, the upper end cover 2 is rotated open. Since the telescopic spring 406 loses external force, it can push the oil separator core bracket 402 to move upward, making it convenient for the user to remove the oil separator core body 401.

[0031] Specifically, such as Figure 1 and Figure 2As shown, an air inlet 8 is installed at a tangential position of the oil-gas separation barrel body 1, and a refueling port 9 is provided below the air inlet 8, the rear end of the oil-gas separation barrel body 1 is connected to an oil outlet 16, and a pressure gauge interface 17 for installing a pressure gauge is provided above the oil outlet 16, the bottom of the oil-gas separation barrel body 1 is connected to a sewage outlet 18 for discharging sewage, one side of the oil-gas separation barrel body 1 is connected to a safety valve connector 7 for installing a safety valve, and an oil sight port 10 is provided on the surface of the oil-gas separation barrel body 1.

[0032] By adopting the above technical solution, the safety valve and the pressure gauge are respectively installed on the safety valve connector 7 and the pressure gauge interface 17, and the air inlet 8 is connected to the compression chamber or the exhaust pipe of the air compressor. The introduced oil-gas mixture enters the oil-gas separation barrel 1 through the air inlet 8, is filtered by the oil separation core body 401, and is discharged outward through the minimum pressure valve 15, while the filtered oil is discharged outward through the oil outlet 16. As the oil-gas separation barrel 1 is used, the lubricating oil in the oil-gas separation barrel 1 is gradually consumed, which can be observed through the position of the transparent oil viewing port 10. When the lubricating oil is less, the lubricating oil is replenished through the refueling port 9.

[0033] Working principle: install the safety valve and pressure gauge on the safety valve joint 7 and the pressure gauge interface 17 respectively, and the air inlet 8 is connected to the compression chamber or exhaust pipe of the air compressor. The introduced oil-gas mixture enters the oil-gas separation barrel 1 through the air inlet 8, is filtered by the oil separator core body 401, and is discharged outward through the minimum pressure valve 15, while the filtered oil is discharged outward through the oil outlet 16. As the oil-gas separation barrel 1 is used, the lubricating oil in the oil-gas separation barrel 1 is gradually consumed, which can be observed through the position of the transparent oil viewing port 10. When the lubricating oil is less, the lubricating oil is replenished through the refueling port 9. During installation, the oil separator core bracket 402 is installed inside the sealing cover plate 11 and is erected above the support plate 403. At this time, under the elastic support of the telescopic spring 406, the oil separator core bracket 402 is higher than the lower end cover 13, and then the cover The upper end cover 2 is put on to close the upper end cover 2 and the lower end cover 13 to each other. Under the pressure of the upper end cover 2, the oil separator core bracket 402 moves downward and compresses the telescopic spring 406. After the telescopic spring 406 is compressed, the oil separator core bracket 402 can be flush with the lower end cover 13. After the oil and gas mixture entering the oil and gas separation barrel 1 is filtered, the gas moves upward from the center position of the oil separator core body 401 to the air circulation groove 3, and reaches the air inlet end of the minimum pressure valve 15 along the air circulation groove 3, and is discharged outward through the minimum pressure valve 15. The upper end cover 2 is fixed to the lower end cover 13 by bolts. After unscrewing the bolts on the upper end cover 2, the upper end cover 2 is rotated to open. Since the telescopic spring 406 loses external force, it can push the oil separator core bracket 402 to move upward, making it convenient for the user to remove the oil separator core body 401.
