Description

Technical Field

[0001] This utility model relates to the field of petroleum extraction technology, specifically to a petroleum extraction oil separator. Background Technology

[0002] In oil extraction, the produced fluids from oil wells often contain crude oil, water, and impurities, requiring efficient separation to improve oil quality. Traditional oil separators mostly rely on gravity settling or simple mechanical separation, which suffers from low separation efficiency and unstable oil-water interfaces. They are particularly unsuitable for high-viscosity, sand-containing, or heavily emulsified crude oils, easily leading to equipment blockage, corrosion, and increased subsequent processing costs. Existing technologies sometimes use heating or chemical demulsification to assist separation, but this is energy-intensive and may contaminate the crude oil. Therefore, there is an urgent need for an oil separator that can adapt to complex reservoir conditions, efficiently and stably separate oil and water, and also possess corrosion and anti-clogging functions to reduce extraction costs and improve resource utilization.

[0003] Chinese patent document CN220434721U discloses an oil separator for petroleum extraction. It includes a stirring chamber, with sedimentation chambers fixedly connected to the top and corresponding sides of the stirring chamber. A first pipe is fixedly connected between the two sedimentation chambers and above the stirring chamber. An oil inlet is fixedly connected to the top of the first pipe. Two first grooves are formed on one side of the oil inlet. Two fixing strips are fixedly connected inside the oil inlet and near the first grooves. A filter box is slidably connected between the two fixing strips. The beneficial effects of this invention are: by employing a stirring mechanism, the oil can be stirred during use using the cooperation of a lead screw, rack, slider, fixing block, second rotating shaft, first rotating shaft, first bevel gear, gear, and motor. This prevents the oil from becoming more viscous due to cooling during separation, thus preventing it from being unable to exit the oil valve and greatly increasing the oil flow rate.

[0004] Although the equipment described in the aforementioned literature can separate oil, its structure is relatively simple, the flow rate at the inlet cannot be adjusted, it is not flexible in use, and the impact force at high flow rates can easily damage the equipment support and reduce its service life. Furthermore, the equipment is inconvenient to clean, which increases the workload for users and reduces the practical value of the equipment. Utility Model Content

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides an oil separator for oil extraction. The device is equipped with an opening and closing mechanism that allows for precise flow management, balancing production efficiency, equipment safety, resource utilization, and environmental protection requirements. Based on the separator's processing capacity and crude oil characteristics, the inlet flow rate is adjusted in real time to prevent overloading or incomplete separation due to excessive flow, or resource waste due to insufficient flow. Maintaining a constant flow input ensures optimal residence time and separation conditions for oil, water, impurities, and other multiphase substances within the separator, improving separation efficiency and crude oil recovery rate. By limiting the flow rate, it prevents sudden pressure spikes caused by instantaneous flow increases, which could lead to equipment damage or explosion. Stable flow reduces erosion and wear on seals, bearings, blades, and other critical components, extending equipment lifespan. A first motor drives a rotating plate, which in turn rotates a baffle, creating channels of varying sizes with the annular frame to facilitate oil flow adjustment.

[0020] This utility model provides an oil separator for oil extraction. The device is equipped with a stirring device, which solves the core pain points of traditional oil separators, such as easy clogging and difficult maintenance, through a synergistic mechanism of "active anti-clogging + high-efficiency cleaning". It has the triple advantages of improved efficiency, cost saving and safety and reliability. The stirring component continuously stirs the fluid in the filter box, preventing oil, silt and other impurities from settling and reducing the risk of filter media clogging. The brush on the stirring rod directly scrapes the filter surface or the inner wall of the box when rotating, physically removing the attached dirt layer, preventing scale hardening and ensuring that the filter channel is always unobstructed. The brush and stirring work together to quickly process high-viscosity crude oil or sandy wastewater, reducing the risk of sudden pipeline blockage or equipment downtime. The drive wheel is driven by a second motor to rotate, so that the driven wheel connected by the synchronous pulley drives the rotating rod to rotate together, thereby making the stirring rod on the rotating rod rotate to stir the dirt and prevent accumulation and blockage. In addition, the brush can wipe the equipment when the stirring rod rotates, improving the cleaning effect.

[0021] This utility model provides an oil separator for oil extraction. The equipment is equipped with a spray device, which can be used for active cleaning and real-time maintenance, balancing equipment efficiency, safety, and environmental protection requirements. The spray system continuously flushes the inner wall and key components of the oil separator with high-pressure water or cleaning fluid, preventing the adhesion and accumulation of impurities such as crude oil, silt, and wax, avoiding blockage or increased flow resistance, keeping the inside of the oil separator clean, ensuring the multiphase separation efficiency of oil, water, and gas, and reducing separation failure or emulsification problems caused by dirt interference. Automated spray cleaning can replace high-frequency manual disassembly and cleaning, reducing labor intensity and safety risks. A pump can draw water from the water tank, separate the water through the first distributor, and deliver it to the first nozzle through the second water pipe, thereby spraying and cleaning the second filter box. Similarly, the second distributor disperses clean water to the second nozzle, thereby spraying and cleaning the first filter box. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 and Figure 5As shown, an oil separator for petroleum extraction includes an inlet 1, with a first filter box 2 fixedly connected to both ends of the inlet 1. An opening / closing device 3 is fixedly connected to one side of the first filter box 2. This device allows for precise flow management, balancing production efficiency, equipment safety, resource utilization, and environmental requirements. Based on the processing capacity of the oil separator and the characteristics of the crude oil, the inlet flow rate is adjusted in real time to avoid overloading the equipment or incomplete separation due to excessive flow, or wasting resources due to insufficient flow. Maintaining a constant flow input ensures that the residence time and separation conditions of oil, water, impurities, and other multiphase substances within the oil separator are optimized. In optimal condition, it improves separation efficiency and crude oil recovery rate. By limiting the flow rate, it avoids the risk of equipment damage or explosion caused by sudden pressure surges due to instantaneous flow spikes in the oil separator. Stabilizing the flow rate reduces the erosion and wear of key components such as seals, bearings, and blades by the fluid inside the oil separator, extending the service life of the equipment. A second filter box 4 is fixedly connected to the middle of the first filter box 2. A stirring device 5 is fixedly connected inside the second filter box 4. Using this device, through the synergistic mechanism of "active anti-clogging + high-efficiency cleaning", it solves the core pain points of traditional oil separators that are prone to clogging and difficult to maintain, while also improving efficiency, saving costs, and ensuring safety. The system boasts three key advantages: a continuously agitating component continuously stirs the fluid within the filter chamber, preventing oil, silt, and other impurities from settling and reducing the risk of filter media clogging; the brush on the agitator directly scrapes the filter surface or inner wall of the chamber during rotation, physically removing existing dirt layers and preventing hardening, ensuring unobstructed filtration channels. The combined action of the brush and agitator allows for rapid processing of high-viscosity crude oil or sand-containing wastewater, minimizing the risk of sudden pipe blockages or equipment downtime. A spray device 6 is fixedly connected to the rear end of the first filter chamber 2, enabling proactive cleaning and real-time maintenance, balancing equipment efficiency, safety, and environmental impact. To ensure compliance, the spray system continuously flushes the inner wall and key components of the oil separator with high-pressure water or cleaning fluid to prevent the adhesion and accumulation of impurities such as crude oil, mud, and wax, avoiding blockage or increased flow resistance, keeping the inside of the oil separator clean, ensuring the multiphase separation efficiency of oil, water, and gas, and reducing separation failure or emulsification problems caused by dirt interference. Automated spray cleaning can replace high-frequency manual disassembly and cleaning, reducing labor intensity and safety risks.

The rotating plate 34 is driven to rotate by the first motor 35, which can drive the baffle 33 to rotate together, thereby forming channels of different sizes with the annular frame 31, which facilitates the adjustment of the oil flow rate.

[0035] like Figure 3 As shown, the output end of the second motor 51 is fixedly connected to the drive wheel 52, and the two sides of the drive wheel 52 are connected to the driven wheels 53. A synchronous belt 54 is provided between the drive wheel 52 and the driven wheels 53. A rotating rod 55 is fixedly connected to the front end of the driven wheel 53. A stirring rod 56 is fixedly connected to one side of the rotating rod 55. A brush plate 57 is fixedly connected to one end of the stirring rod 56. The second motor 51 drives the drive wheel 52 to rotate, so that the driven wheel 53 connected through the synchronous belt 54 drives the rotating rod 55 to rotate together. This causes the stirring rod 56 on the rotating rod 55 to rotate and stir the dirt, preventing accumulation and blockage. In addition, the brush plate 57 can wipe the equipment when the stirring rod 56 rotates, improving the cleaning effect.

[0036] like Figure 4 As shown, the output end of the pump 61 is fixedly connected to a first water pipe 62. A first diverter 63 is fixedly connected to one side of the first water pipe 62.

A third water pipe 68 is fixedly connected to the output end of the second diverter 67. A second nozzle 69 is fixedly connected to one end of the third water pipe 68. The pump 61 can draw water from the water tank, which is then separated by the first diverter 63 and transported to the first nozzle 65 via the second water pipe 64 for spraying, thereby cleaning the second filter box 4. Similarly, the second diverter 67 disperses clean water to the second nozzle 69 for spraying, thereby cleaning the first filter box 2.

[0037] The working principle of this utility model is as follows: Through the opening and closing device 3, the first motor 35 drives the rotating plate 34 to rotate, which can drive the baffle 33 to rotate together, thereby forming channels of different sizes with the ring frame 31, which facilitates the adjustment of oil flow. Using the stirring device 5, the second motor 51 drives the driving wheel 52 to rotate, so that the driven wheel 53 connected by the synchronous pulley belt 54 drives the rotating rod 55 to rotate together, thereby causing the stirring rod 56 on the rotating rod 55 to rotate and stir the dirt, preventing accumulation and blockage. In addition, a brush plate 57 is set to wipe the equipment when the stirring rod 56 rotates, improving the cleaning effect. Through the spraying device 6, the pump 61 can draw water from the water tank, and the water is separated by the first diverter 63 and transported to the first nozzle 65 through the second water pipe 64 for spraying, thereby spraying and cleaning the second filter box 4. Similarly, the second diverter 67 disperses and transports clean water to the second nozzle 69 for spraying, thereby spraying and cleaning the first filter box 2.
