Description

Technical Field

[0001] The utility model relates to the technical field of oil-gas separators, in particular to a built-in oil-gas separator. Background Art

[0002] An oil-gas separator is a device used to effectively separate oil mist and gas in compressed air. It is widely used in various compressed air systems, particularly in oil-lubricated air compressors. Its primary function is to ensure that the air discharged from the compressor contains as little lubricating oil as possible, thereby improving air quality and minimizing the impact on downstream equipment. It also allows the lubricating oil to be recovered for reuse.

[0003] Based on the above, the inventors found the following problems: the existing oil-gas separator is usually arranged on the outside of the compressor, which requires additional installation space, and the separated lubricating oil cannot be directly returned to the compressor for continued use, which is inconvenient to use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a built-in oil-gas separator is provided to achieve a purpose with greater practical value. Utility Model Content

[0005] The purpose of the present utility model is to provide a built-in oil-gas separator to solve the problems raised in the above-mentioned background technology. A built-in oil-gas separator includes a compressor assembly, the compressor assembly includes a compression chamber, an end cover is fixedly installed at one end of the compression chamber, an exhaust pipe is provided in the middle of the top of the end cover, an oil-gas separation assembly is provided inside the exhaust pipe, the oil-gas separation assembly includes a fixed pipe, the outer side of the fixed pipe is fixedly connected to the inner side of the exhaust pipe, an oil storage chamber is fixedly installed at the bottom end of the inner side of the fixed pipe, an air inlet is provided at the bottom of the oil storage chamber, a return pipe is connected to one side of the oil storage chamber, a return interface is provided on one side of the top of the end cover, the bottom end of the return pipe is connected to the return interface, and a liquid level control valve is provided inside the other end of the return pipe.

[0006] By adopting the above technical solution, an exhaust pipe is provided through the middle part of the top of the end cover, so that the gas compressed by the compressor assembly can be discharged from the exhaust pipe. The setting of the fixed pipe facilitates the fixed installation of the oil-gas separation assembly inside the exhaust pipe. An oil storage chamber is fixedly installed through the bottom end of the inner side of the fixed pipe, and an air inlet is provided at the bottom of the oil storage chamber, so that the compressed gas can enter the oil-gas separation assembly from the air inlet for oil-gas separation. The separated lubricating oil enters the oil storage chamber for storage, and is connected to the reflux interface through the bottom end of the reflux pipe. A liquid level control valve is provided inside the other end of the reflux pipe, so that when the lubricating oil stored in the oil storage chamber reaches a certain amount, the liquid level control valve is opened to return the oil to the compressor assembly, so as to facilitate the recycling of the separated lubricating oil.

[0007] Furthermore, an outer separation tube and an inner separation tube are fixedly installed on the top of the oil storage chamber, and the air inlet is opened between the outer separation tube and the inner separation tube.

[0019] Furthermore, an electromagnetic clutch is fixedly mounted on one end of the compression chamber away from the end cover, and one side of the electromagnetic clutch is rotatably connected to a pulley.

[0020] By adopting the above technical solution, a pulley is connected by rotating on one side of the electromagnetic clutch, so that external equipment can use the transmission belt to drive the compressor assembly to work.
