Description

Technical Field

[0001] This invention belongs to the field of mixed oil interface detection technology, and specifically relates to a mixed oil interface detector. Background Technology

[0002] In the petrochemical and oil and gas storage and transportation sectors, pipelines often need to transport different types or batches of oil products (such as crude oil, refined oil, and fuel oil). During the transportation of different oil products (such as 92# gasoline, 95# gasoline, aviation kerosene, crude oil, and methanol) in long-distance pipelines, a mixing interface inevitably forms between the different oil products. Accurately monitoring the location and degree of mixing of this interface is a key step in reducing the amount of mixed oil, lowering secondary refining costs, and ensuring the purity of the distributed oil.

[0003] Existing oil identification methods mainly rely on equipment such as online densitometers, viscometers, or near-infrared spectrometers. However, traditional detection instruments are mostly fixed structures, and the orientation and spacing of their inlets and outlets are difficult to adjust flexibly according to the actual pipeline route, increasing construction difficulty and leakage risk. At the same time, during the start-up, switching, or maintenance and restoration of oil pipelines, air or other gases are often mixed into the pipeline. These gases enter the detector in the form of bubbles or slug flows, causing the detection sensor to fail to contact the actual oil, resulting in signal jumps or failures. Furthermore, the oil in the pipeline is in a continuous flow state, and the oil is often accompanied by eddies, pulsations, and small amounts of gas or moisture. Conventional detection methods are easily affected by changes in flow velocity, bubble interference, or oil temperature fluctuations under dynamic flow conditions, resulting in a decrease in the ability to distinguish different types of oil, and the repeatability and linearity are difficult to meet the requirements of refined production control. Therefore, those skilled in the art have provided an oil mixing interface detector to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed oil mixing interface detector in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions: An oil mixing interface detector includes a fixed tube, a protective sleeve fixedly connected to the side wall of the fixed tube, a control module provided at the top of the fixed tube, a detection component provided at the bottom of the fixed tube, an exhaust component provided at the bottom of the detection component, and connecting components provided on the side wall of the exhaust component and the side wall of the protective sleeve, respectively.

[0007] As a further optimization of the present invention, a collar is sleeved on the side wall of the second connecting pipe, and a connecting rod is rotatably connected to both sides of the collar. One end of one connecting rod is rotatably connected to the side wall of the rotating ring, and the other end of the other connecting rod is rotatably connected to the side wall of the fixed sleeve.

[0008] As a further optimization of the present invention, the detection assembly includes a detection shell that is fixedly connected to the fixed tube, a first blade that is rotatably connected to the inner wall of the detection shell, a detection sensor module that is disposed on one side of the inner wall of the detection shell, a signal transmission module that is electrically connected to the detection sensor module that is fixedly connected to the side wall of the detection shell, and a sealing connection mechanism that is disposed at the bottom end of the detection shell.

[0009] As a further optimization of the present invention, the sealing connection mechanism includes a detection tube that is fixedly connected to the inside of the detection shell, a first flange is fixedly sleeved at the bottom end of the detection tube, a sealing tube is fixedly connected to the bottom end of the inner wall of the detection tube, and a detection module is provided inside the detection tube.

[0010] As a further optimization of the present invention, the detection module includes a flow tube fixedly connected to the inner wall of the detection tube, a guide vane fixedly connected to the bottom end of the inner wall of the flow tube, and a second vane rotatably connected to the top end of the inner wall of the guide vane.

[0011] As a further optimization of the present invention, the exhaust assembly includes an inlet pipe that is fixedly connected to one end of a first connecting pipe, another first connecting pipe that is fixedly connected to a fixed pipe through a protective sleeve, the top end of the inlet pipe being fixedly fitted with a second flange that mates with a first flange, the top end of the inner wall of the inlet pipe being provided with a filter mechanism, and the top end of the inlet pipe being provided with a plurality of exhaust mechanisms.

[0012] As a further optimization of the present invention, the filtration mechanism includes a drain pipe that is sealed and sleeved with the side wall of the sealing tube. The drain pipe is fixedly connected to the top of the inner wall of the inlet pipe. A limit ring is fixedly connected to the inner wall of the drain pipe, and a filtration module is provided at the top of the limit ring.

[0013] As a further optimization of the present invention, the exhaust mechanism includes an exhaust pipe that is fixedly connected to the top end of the liquid inlet pipe, a first fixing frame is fixedly connected to the top end of the inner wall of the exhaust pipe, a first sliding rod is slidably connected through the middle of the first fixing frame, a first sealing plug is fixedly connected to the bottom end of the first sliding rod, and a spring is sleeved on the side wall of the first sliding rod and fixedly connected to the bottom end of the first fixing frame.

[0014] As a further optimization of the present invention, a second fixing frame is fixedly connected to the bottom end of the inner wall of the exhaust pipe, a second sliding rod is slidably passed through the middle of the second fixing frame, a float that cooperates with the bottom end of the exhaust pipe is fixedly connected to the bottom end of the second sliding rod, and a second sealing plug is fixedly connected to the top end of the second fixing frame.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, by setting a connecting component, the entire device is placed between the input and output pipes of the oil circuit. The connecting component connected to the exhaust component is connected to the input pipe of the oil circuit. Before the connection process, the second connecting pipe is rotated by rotating the rotating ring to adjust the orientation of the flexible pipe, ensuring that the flexible pipe can be better connected to the input pipe. At the same time, the threaded sleeve is rotated to adjust the combined length between the screw and the threaded sleeve, so that the connecting rod and the flexible pipe can be bent at the position of the collar. By fine-tuning the port of the flexible pipe, the two connecting components are connected to the input and output pipes respectively.

[0016] 2. In this invention, by setting up a detection component, after the oil enters the sealed pipe through the exhaust component, it first enters the flow pipe. After passing through the guide vanes in the flow pipe, the oil is guided and flows into the second vane in a spiral shape, causing the second vane to rotate and stir the mixed oil. At the same time, after the oil enters the detection shell, it impacts the first vane, causing the first vane to rotate. The rotation of the first vane can be used to calculate the arrival time of the mixed liquid, effectively assisting in the measurement data. Meanwhile, using the detection sensor module on one side of the inner wall of the detection shell, multiple parameters of the oil passing through the detection shell can be comprehensively measured, effectively improving the detection range of multiple oil types, improving the reliability of the detection, and making the measurement results more realistic, accurate, and stable.

[0017] 3. In this invention, by setting up an exhaust assembly, during the process of oil entering the input pipe, the oil first enters the inlet pipe through the connecting assembly. In the gap between the inlet pipe and the outlet pipe, the air, due to its lower density, floats to the top of the inner wall of the inlet pipe. The oil gradually fills the inlet pipe under the action of gravity and enters the detection assembly through the outlet pipe. As the oil gradually fills the inside of the inlet pipe, it compresses the air into the exhaust pipe, thereby ejecting the air through the exhaust pipe. When the inlet pipe is filled with oil, the float will be buoyed by the oil, causing the float to move the second sliding rod, thereby pushing the second sealing plug to seal the inside of the exhaust pipe, effectively preventing oil from overflowing, thus realizing the discharge of gas in the oil and avoiding affecting the detection of oil waste heat.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 As shown, an oil mixing interface detector includes a fixed tube 5, a protective sleeve 4 fixedly connected to the side wall of the fixed tube 5, a control module 6 at the top of the fixed tube 5 (the control module 6 is prior art), a detection component 2 at the bottom of the fixed tube 5, an exhaust component 3 at the bottom of the detection component 2, and connecting components 1 respectively provided on the side wall of the exhaust component 3 and the side wall of the protective sleeve 4.

[0022] like Figure 1 , Figure 2As shown, the connecting assembly 1 includes a first connecting pipe 101, one of which is fixedly connected to a fixed pipe 5 through a protective sleeve 4. A valve 102 is provided in the middle of the first connecting pipe 101, and a fixed bracket 103 is fixedly sleeved on the side wall of the other end of the first connecting pipe 101. A pressure gauge 104 is provided on the side wall of the first connecting pipe 101. A rotating ring 112 is rotatably connected to one side of the fixed bracket 103. The rotating ring 112 is rotatably provided on the side wall of the fixed bracket 103, and a second valve 104 is fixedly connected to the first connecting pipe 101 through the middle of the rotating ring 112. The connecting pipe 106 has a flexible pipe 108 fixedly connected to its other end. The flexible pipe 108 is a prior art technology and is a pipe that can be bent and has a certain degree of flexibility. The entire device is placed between the input pipe and the output pipe of the oil circuit. The connecting component 1, which is connected to the exhaust component 3, is connected to the input pipe of the oil circuit. Before the connection process, the second connecting pipe 106 is rotated by rotating the rotating ring 112 to adjust the orientation of the flexible pipe 108 and ensure that the flexible pipe 108 can be better connected to the input pipe.

[0023] like Figure 1 , Figure 2 As shown, a threaded sleeve 111 is movably connected to the bottom end of the rotating ring 112, and a fixed sleeve 109 is fixedly sleeved on the side wall of the flexible tube 108. The fixed sleeve 109 is sleeved in the middle area of ​​the flexible tube 108. After the angle between the flexible tube 108 and the second connecting tube 106 is adjusted, one end of the flexible tube 108 can be finely adjusted, which effectively improves the installation effect. A screw 110 that is threaded to the threaded sleeve 111 is rotatably connected to the bottom end of the fixed sleeve 109. By rotating the threaded sleeve 111, the combined length between the screw 110 and the threaded sleeve 111 can be adjusted, so that the connecting rod 105 and the flexible tube 108 can be bent at the position of the collar 107. By finely adjusting the port of the flexible tube 108, the two connecting components 1 can be connected to the input pipe and the output pipe respectively.

[0024] like Figure 1 , Figure 2 As shown, a collar 107 is fitted on the side wall of the second connecting pipe 106. Connecting rods 105 are rotatably connected to both sides of the collar 107. One end of one connecting rod 105 is rotatably connected to the side wall of the rotating ring 112, and the other end of the other connecting rod 105 is rotatably connected to the side wall of the fixed sleeve 109. The collar 107 is fitted on the side wall of the second connecting pipe 106, and two connecting rods 105 are respectively provided on both sides of the collar 107. A stable triangular structure is formed between the collar 107, the threaded sleeve 111, and the screw 110 to form a pipe. This can improve the stability of the pipe after the angle between the second connecting pipe 106 and the flexible pipe 108 is adjusted.

[0025] like Figure 1 , Figure 3- Figure 8 As shown, the detection assembly 2 includes a detection shell 201 fixedly connected to the fixed tube 5. A first blade 204 with a counting function is rotatably connected to the inner wall of the detection shell 201. The first blade 204 with a counting function is a conventional component in a flow meter and belongs to the prior art. A detection sensor module 202 is disposed on one side of the inner wall of the detection shell 201. A signal transmission module 203 electrically connected to the detection sensor module 202 is fixedly connected to the side wall of the detection shell 201. The signal transmission module 203 is the prior art and is used to transmit signals to the control module 6. The control module 6 centrally processes the received signals and utilizes the detection sensor module 202 on one side of the inner wall of the detection shell 201. Block 202 can perform comprehensive multi-parameter measurements on the oil passing through the detection shell 201, effectively improving the detection range of multiple oil types, enhancing detection reliability, and making the measurement results more realistic, accurate, and stable. The detection sensor module 202 is a prior art technology, including sensor modules such as a temperature measurement unit, a pressure measurement unit, a sound absorption energy measurement unit, an infrared spectrum measurement unit, and a permittivity measurement unit. By analyzing and measuring the medium through multiple sensors, more realistic, accurate, and stable measurement results are obtained. The multi-parameter measurement is suitable for various oil types, with a wider measurement range, adapting to the oil characteristics of various sites, and providing users with an accurate means of monitoring the oil mixing interface.

[0026] like Figure 1 , Figure 3 - Figure 8 As shown, a detection tube 205 is fixedly connected inside the detection housing 201. A first flange 206 is fixedly sleeved at the bottom end of the detection tube 205. A sealing tube 207 is fixedly connected to the bottom end of the inner wall of the detection tube 205. The detection component 2 and the exhaust component 3 can be installed using the first flange 206, which facilitates the maintenance and repair of the entire device.

[0027] like Figure 1 , Figure 3 - Figure 8 As shown, a flow tube 208 is fixedly connected to the inner wall of the detection tube 205. A guide vane 209 is fixedly connected to the bottom of the inner wall of the flow tube 208. A second vane 210 is rotatably connected to the top of the inner wall of the guide vane 209. After the oil enters the sealing tube 207 through the exhaust assembly 3, it first enters the flow tube 208. After passing through the guide vane 209 in the flow tube 208, the oil flows into the second vane 210 in a spiral shape, causing the second vane 210 to rotate. The rotation of the second vane 210 stirs the mixed oil, making it fully mixed before entering the detection shell 201, thus improving the accuracy of the detection. At the same time, after the oil enters the detection shell 201, it impacts the first vane 204, causing the first vane 204 to rotate. The rotation of the first vane 204 can be used to calculate the arrival time of the mixed liquid, effectively assisting in the measurement data.

[0028] like Figure 1 , Figure 6 - Figure 10 As shown, the exhaust assembly 3 includes an inlet pipe 301 that is fixedly connected to one end of another first connecting pipe 101. The top end of the inlet pipe 301 is fixedly fitted with a second flange 305 that mates with the first flange 206. The side wall of the sealing pipe 207 is fitted with a drain pipe 304. The drain pipe 304 is fixedly connected to the top end of the inner wall of the inlet pipe 301. During the process of the oil entering the pipeline, the oil first enters the inlet pipe 301 through the connecting assembly 1. In the gap between the inlet pipe 301 and the drain pipe 304, due to the low density of air, it floats to the top of the inner wall of the inlet pipe 301. The oil gradually fills the inlet pipe 301 under the action of gravity and enters the detection assembly 2 through the drain pipe 304.

[0029] like Figure 1 , Figure 6 - Figure 10 As shown, a limiting ring 306 is fixedly connected to the inner wall of the drain pipe 304. A filter module 303 is provided at the top of the limiting ring 306. The filter module 303 is installed in the drain pipe 304. The filter module 303 is a prior art technology and is composed of multiple layers of filter screens. It can filter and clean the oil before it enters the detection component 2, thereby improving the accuracy of the detection. At the same time, by using the sealing pipe 207 and the limiting ring 306, the sealing performance of the drain pipe 304 can be improved, while limiting the filter module 303, effectively improving the stability.

[0030] like Figure 1 , Figure 6 - Figure 10 As shown, an exhaust pipe 302 is fixedly inserted through the top of the inlet pipe 301. A first fixing bracket 308 is fixedly connected to the top of the inner wall of the exhaust pipe 302. A first sliding rod 307 slides through the middle of the first fixing bracket 308. A first sealing plug 310 is fixedly connected to the bottom of the first sliding rod 307. A spring 309 is sleeved on the side wall of the first sliding rod 307. The two ends of the spring 309 are fixedly connected to the bottom of the first fixing bracket 308 and the first sealing plug 310. By setting the first sealing plug 310 in the exhaust pipe 302 and using the spring 309 to apply elastic force, a one-way sealing effect is achieved, preventing external impurities from entering and causing oil contamination.

[0031] like Figure 1 , Figure 6 - Figure 10As shown, a second fixing bracket 312 is fixedly connected to the bottom of the inner wall of the exhaust pipe 302. A second sliding rod 313 slides through the middle of the second fixing bracket 312. A float 314 that mates with the bottom of the exhaust pipe 302 is fixedly connected to the bottom of the second sliding rod 313. The float 314 has an ellipsoidal structure. When the second sealing plug 311 moves upward to seal the exhaust pipe 302, the float 314 fits against the bottom of the exhaust pipe 302, further improving the sealing effect and preventing oil leakage. A second fixing bracket 312 is fixedly connected to the top of the second fixing bracket 312. As the oil gradually fills the inlet pipe 301, the second sealing plug 311 compresses air into the exhaust pipe 302, thereby ejecting the air through the exhaust pipe 302. When the inlet pipe 301 is filled with oil, the float 314 will be buoyed by the oil, causing the float 314 to move the second sliding rod 313, which in turn pushes the second sealing plug 311 to seal the inside of the exhaust pipe 302, effectively preventing oil from overflowing and thus venting the gas in the oil, avoiding any impact on the detection of oil waste heat.

[0032] It should be noted that, in use, this oil mixing interface detector is placed between the input and output pipes of the oil circuit. The connecting component 1, which is connected to the exhaust component 3, is connected to the input pipe of the oil circuit. Before the connection process, the second connecting pipe 106 is rotated by rotating the rotating ring 112 to adjust the orientation of the flexible pipe 108, ensuring that the flexible pipe 108 can be better connected to the input pipe. At the same time, the threaded sleeve 111 is rotated to adjust the combined length between the screw 110 and the threaded sleeve 111, so that the connecting rod 105 and the flexible pipe 108 can be bent at the position of the collar 107. By fine-tuning the port of the flexible pipe 108, the two connecting components 1 are connected to the input pipe and the output pipe respectively. During the oil transportation process, the oil first enters the inlet pipe 301 through the connecting component 1. In the gap between the inlet pipe 301 and the outlet pipe 304, the air, due to its lower density, rises to the top of the inner wall of the inlet pipe 301. The oil gradually fills the inlet pipe 301 under the action of gravity and enters the detection component 2 through the outlet pipe 304. As the oil gradually fills the inside of the inlet pipe 301, it compresses the air into the exhaust pipe 302, thereby spraying the air out through the exhaust pipe 302. When the inlet pipe 301 is filled with oil, the float 314 is buoyed by the oil, causing the float 314 to drive the second sliding rod 313 to move, thereby pushing the second sealing plug 311 to seal the inside of the exhaust pipe 302, effectively preventing the oil from overflowing, thus realizing the discharge of gas in the oil and avoiding affecting the detection results. After the oil enters the sealing pipe 207 through the exhaust assembly 3, it first enters the flow pipe 208. After passing through the guide vane 209 in the flow pipe 208, it flows into the second vane 210 in a spiral shape, causing the second vane 210 to rotate and stir the oil mixture. Simultaneously, after the oil enters the detection shell 201, it impacts the first vane 204, causing the first vane 204 to rotate. The rotation of the first vane 204 can be used to calculate the arrival time of the mixed liquid, effectively assisting in the measurement data. At the same time, the detection sensor module 202 on one side of the inner wall of the detection shell 201 can perform comprehensive multi-parameter measurements on the oil passing through the detection shell 201. The detection sensor module includes a temperature measurement unit, a pressure measurement unit, a sound absorption energy measurement unit, an infrared spectrum measurement unit, a permittivity measurement unit, and other sensor modules. Among them, the sound absorption energy measurement is based on the fact that, under a certain density of the medium, ultrasonic waves can move along the same wave direction. The ultrasonic wave propagates along a straight line, and the change in ultrasonic energy received by the receiver is used to determine the change in the type of oil in the pipeline. When the liquid is irradiated with infrared light, the chemical bonds or functional groups in the molecules can vibrate and absorb. Different chemical bonds or functional groups have different absorption frequencies and will be located at different positions on the infrared spectrum, thus obtaining information about what kind of chemical bonds or functional groups are contained in the molecules, thereby determining the characteristics and changes of the oil. The permittivity measurement unit distinguishes and measures different oils based on their different dielectric constants, while also addressing the influence of temperature on capacitance changes, thus improving the resolution and sensitivity of the measurement. The temperature measurement unit and pressure measurement unit, as compensation signals, together with the acoustic absorption energy measurement unit, infrared spectrum measurement unit, and infrared spectrum measurement unit, transmit the signals to the control module 6 through the signal transmission module 203. The control module 6 then processes the signals and finally outputs the signals, plotting the oil circuit change curve, thereby realizing the detection of the mixed oil interface.

[0033] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
