Description

Technical Field

[0001] This utility model relates to an oil-gas separator. Background Technology

[0002] Screw air compressors are efficient and reliable pneumatic power source devices for compressing gases, widely used in manufacturing, industrial production, and many other industries. During the gas compression process, a large amount of lubricating oil is injected into the compression chamber for cooling, sealing, and lubrication, generating a high-temperature, high-pressure oil-gas mixture. Air compressors need to perform coarse and fine separation of this oil-gas mixture to achieve efficient separation of lubricating oil and compressed air, ensuring clean compressed air. Therefore, an oil-gas separator is required for oil-gas separation. The compressed oil-gas mixture is discharged to the oil separator tank. First, within the tank, a cyclone separator separates most of the lubricating oil. This lubricating oil settles to the bottom of the tank and, through the oil spray nozzle, is cooled and circulated back into the main unit. Simultaneously, a portion of the gas undergoes fine separation through an oil-gas separator core installed above the tank, filtering out any residual lubricating oil. The gas then travels through pipelines, undergoes further cooling, and is delivered to the user.

[0003] Currently used oil-gas separators integrate oil return and gas delivery all within the lid. The oil return pipe is inserted through the lid, making it impossible to observe the interior of the separator. Furthermore, installation errors in the piping result in insufficient oil return, leading to excessive lubricating oil in the compressed air. In addition, the oil-gas separator core requires periodic replacement, necessitating the removal of the minimum pressure valve, oil return pipe, and vent pipe from the lid. This cumbersome and time-consuming process for after-sales personnel during maintenance is inefficient and inconvenient, impacting customer production. Utility Model Content

[0004] The main technical problem to be solved by this utility model is to provide an oil-gas separator that can reduce oil tank vibration; facilitate the replacement of the oil-gas separator core; prevent lubricating oil from accumulating at the bottom of the oil separator core, allowing for sufficient oil return, thereby reducing the oil content in the compressed air; and also prevent the safety valve from spraying oil droplets that may accidentally injure the user.

[0005] To solve the above-mentioned technical problems, this utility model provides a flat-cover oil-gas separator, including: an oil-gas separator body, a flat-cover barrel cover disposed on the top of the oil-gas separator body, a detachable safety valve cover disposed on the side of the oil-gas separator body, a coarse separation component disposed inside the oil-gas separator body, barrel feet disposed at the bottom of the oil-gas separator body, and an oil separator gas outlet assembly disposed below the flat-cover barrel cover.

[0006] The oil separator outlet assembly is equipped with an oil-gas separator core support, and an oil-gas separator core is installed above the oil-gas separator core support to filter out the residual lubricating oil in the oil-gas mixture entering the oil-gas separator core; the side of the oil separator outlet assembly is connected to an oil return pipe below the oil-gas separator core for oil return inside the oil-gas separator core.

[0007] The coarse separation component is used for the initial coarse separation of oil and gas mixtures.

[0008] In a preferred embodiment: the oil-gas separator core support includes a fully threaded screw, a fixing ring, and an oil separator core support plate; one end of the fully threaded screw passes through the fixing ring and is fixed to the oil separator core support plate.

[0009] In a preferred embodiment: a rubber shock-absorbing pad is provided below the barrel feet for shock absorption of the oil-gas separator.

[0010] In a preferred embodiment: a pressure plate is provided above the oil-gas separator core for fixing the oil-gas separator core, and the pressure plate is connected to the side of the full-thread screw away from the oil separator core support plate.

[0011] In a preferred embodiment: an outlet flange is provided on the side of the oil separator gas outlet assembly, and the outlet flange is connected to a minimum pressure valve to separate clean gas and transport it from the outlet pipeline.

[0012] In a preferred embodiment: the oil separator vent assembly is provided with an oil receiving flange outside the vent pipe, one end of the oil return pipe is connected to the oil return connector of the vent flange, and the other end is connected to the oil return port of the oil receiving flange for oil return inside the oil-gas separator core.

[0013] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0014] This utility model provides a new type of flat-cover oil-gas separator, on which the oil-gas separator core is installed with its opening facing downwards. The gas delivery pipe and oil return pipe are connected from the side of the oil separator. When replacing the oil separator core, the oil tank cover is opened and the pressure plate is removed to replace the oil separator core. The replacement of the oil separator core is convenient.

[0015] This utility model provides a new type of flat-cover oil-gas separator. The bottom of the oil-gas separator is equipped with shock-absorbing feet, which effectively reduces the vibration of the oil tank. A safety valve cover is installed on the side of the oil-gas separator to prevent the safety valve from spraying oil droplets and accidentally injuring the user.

[0016] This utility model provides a new type of flat-cover oil-gas separator with oil return at the bottom of the oil separator core. Oil will not accumulate at the bottom of the oil separator core, and oil can be fully returned, thereby reducing the oil content in the compressed air.

[0017] Therefore, this utility model solves the problems of after-sales maintenance of oil-gas separators, barrel vibration, inconvenient installation of return oil pipelines, and low return oil efficiency in the existing technology, and has the advantages of simple after-sales maintenance, low vibration, and high return oil efficiency.

Rubber shock-absorbing pads are provided under the barrel feet 1 at the bottom of the oil tank 2 for shock absorption of the oil-gas separation tank 2.

[0025] In use, an oil-gas separator core (oil separator core) is installed above the oil-gas separator core support 7, with its opening facing downwards. This is used to filter the residual lubricating oil entering the oil-gas separator core, preventing oil from accumulating at the bottom of the oil separator core and allowing for sufficient oil return, thus reducing the oil content in the compressed air. A pressure plate 5 is installed above the oil-gas separator core for fixing it. An oil receiving flange 802 and an oil return pipe 805 are connected to the oil outlet assembly 8 of the oil separator tank. The oil return pipe 805 is connected to the oil return connector 804 installed on the outlet flange 803 for the oil return function inside the oil-gas separator core.

[0026] The oil separator vent assembly 8 has a side vent flange 803 connected to a minimum pressure valve, which separates clean gas and delivers it through the vent pipe 801. Additionally, the vent flange 803 is equipped with a return oil check valve for delivering lubricating oil from the oil-gas separator core. The vent flange 803 and return oil pipe 805 are located on the side of the oil-gas separator 2, making it very convenient to replace the oil-gas separator core.
