Description

Technical Field

[0001] The present invention relates to the technical field of crude oil water content measurement, and specifically to a high-precision rapid crude oil water content detector. Background Art

[0002] During the crude oil processing, excessive water content will cause unstable operation of the distillation column. In severe cases, materials are likely to rush out of the distillation column. At the same time, excessive water content will increase the energy consumption of the atmospheric and vacuum distillation unit and increase the consumption of cooling water. In addition, when conducting crude oil trade, the level of water content affects the interests of both trading parties. Therefore, accurate measurement of water content is required before crude oil enters the factory and the processing unit to provide reference data for crude oil trade, processing, etc. The detection methods for measuring the water content of crude oil include: centrifugation method, distillation method, and electromagnetic wave penetration method. The centrifugation method is based on the density difference between crude oil and water, and oil and water are separated in a centrifuge to detect the water content of crude oil. The distillation method uses the different boiling points of crude oil, water, and solvent to analyze the water content of crude oil. The electromagnetic wave penetration method uses the different dielectric constants of oil, water, and air to detect the total dielectric constant of the oil-water mixture through electromagnetic wave dielectric constant detection technology.

[0003] When detecting the water content of crude oil in the prior art, the centrifugation method and the distillation method are usually used to detect the water content of crude oil. When high accuracy and rapid detection are required, the electromagnetic wave penetration method is usually used to detect the water content of crude oil. When using the electromagnetic wave penetration method to detect the water content of crude oil, the sampled crude oil needs to be placed in the detector for detection. When detecting different amounts of sampled crude oil, the liquid level height of the crude oil is different, and the range where the electromagnetic wave is emitted in the detector is usually in the middle position of the detector. Different liquid level heights of the crude oil cannot ensure that the sample is in the middle position of the electromagnetic wave, thus affecting the detection accuracy. Summary of the Invention

[0032] The pushing mechanism includes a second pushing rod 16, which is elastically slidably connected to the surface of the support frame 7, and the second pushing rod 16 penetrates the support frame 7 and extends to the bottom of the support frame 7. The upper end of the second pushing rod 16 is fixedly connected to a pushing plate 17, and the bottom of the inner wall of the mounting shell 1 is fixedly connected to a support rod 18, and the upper end of the support rod 18 is hinged with a swing rod 19, and both ends of the swing rod 19 are telescopic rods.

[0033] The fixing mechanism includes a rotating ring 22, which is elastically rotatably connected to the surface of the mounting shell 1, the placement tube 6 is located inside the rotating ring 22, a plurality of toggle blocks 23 are fixedly connected to the surface of the rotating ring 22, a plurality of arc-shaped guide grooves 24 are opened on the surface of the rotating ring 22, a plurality of through grooves 25 are opened on the surface of the placement tube 6, a clamping plate 26 is slidably connected in the through groove 25, and the bottom of the clamping plate 26 slides in the guide groove 24;

[0034] In the process of testing the water content of crude oil, it is necessary to place the sampling bottle containing the crude oil sample into the placing tube 6, and the rotating ring 22 is rotated by a certain angle by the toggle block 23. The clamping plate 26 will move to the outside of the placing tube 6 under the action of the guide groove 24, and then the sampling bottle containing the crude oil sample is placed inside the placing tube 6. The bottom of the sampling bottle will first contact the lifting plate 8, and the lifting plate 8 will move downward under the gravity of the sampling bottle and the crude oil. The lifting spring 10 is compressed, and the lifting plate 8 can move the crude oil part in the sampling bottle to the middle of the electromagnetic transmitting end 2 and the electromagnetic receiving end 3 according to the gravity of the sampling bottle and the crude oil. The electromagnetic wave is placed in a position where the electromagnetic wave is concentrated, so that the position where the electromagnetic wave is concentrated can pass through the middle of the crude oil, thereby improving the accuracy of electromagnetic wave detection of the water content of the crude oil, and avoiding that when the sampling bottle contains different amounts of crude oil, the liquid level of the crude oil is different, and the position where the electromagnetic wave is most concentrated cannot pass through the middle position of the crude oil, thereby affecting the accuracy of the detection of the water content in the crude oil. After the sampling bottle is placed in the placement barrel, the toggle block 23 is released, the rotating ring 22 will return to its original position, and the clamping plate 26 will move back to the inside of the placement barrel under the action of the guide groove 24. The clamping plate 26 will clamp the sampling bottle, so that the sampling bottle can be kept during the detection process. Stable. When there is a lot of crude oil in the sampling bottle, when the sampling bottle is placed in the placement barrel, the weight of the sampling bottle and the crude oil is large. When the sampling bottle moves to the bottom of the placement barrel, when the sampling bottle moves to the position of the squeezing block 15, the sampling bottle will act on the squeezing block 15 to move to the outside of the placement barrel. The movement of the squeezing block 15 will act on the first pushing rod 14 to move upward. The first pushing rod 14 will act on the clamping block 13 to move into the placement barrel. The clamping block 13 will clamp the sampling bottle, so that the clamping block 13 can clamp and decelerate the sampling bottle when it moves to the bottom of the placement barrel, so as to avoid collision between the sampling bottle and the bottom of the placement barrel. After the test is completed, the toggle block 23 is moved to act on the rotating ring 22 to release the clamping plate 26 from clamping the sampling bottle. Then, by pressing the pressing rod 21 downward, the pressing rod 21 will act on the swing rod 19 to rotate around the support rod 18. The rotation of the swing rod 19 will act on the second pushing rod 16 and the pushing plate 17 to move upward. The pushing plate 17 will act on the sampling bottle placed at the bottom of the placement barrel to move upward together with the lifting plate 8. The upper end of the sampling bottle will move out of the placement barrel, making it easy to take out the sampling bottle containing more crude oil from the inside of the placement barrel, reducing the time of additional operating steps in the process of detecting the water content of crude oil and improving the detection efficiency.

[0035] After the water content of the crude oil is detected and the sampling bottle is taken out, the operating block 23 and the pressing rod 21 need to be operated simultaneously, and the operation is rather cumbersome. As a further solution of the present invention, a triangular pushing block 27 is fixedly connected to the side of the rotating ring 22 close to the pressing rod 21. An extrusion rod 28 is elastically slidably connected to the surface of the mounting shell 1. The side of the extrusion rod 28 close to the pushing block 27 is an inclined surface. The extrusion rod 28 extends to the position of the pushing block 27. The end of the extrusion rod 28 close to the pressing rod 21 fits against the surface of the pressing rod 21. A triangular acting block 29 is fixedly connected to the side of the pressing rod 21 close to the extrusion rod 28;

[0036] After the detection of the crude oil is completed and the sampling bottle containing more crude oil needs to be taken out, when pressing down the pressing rod 21, the pressing rod 21 will drive the acting block 29 to move downward together. The acting block 29 will act on the extrusion rod 28 to move toward the side close to the pushing block 27. The extrusion rod 28 will act on the pushing block 27 and the rotating ring 22 to rotate to one side. The rotation of the rotating ring 22 will act on the clamping plate 26 to move away from the placement barrel. During the process of pressing the pressing rod 21, the rotating ring 22 can be driven to rotate together to release the clamping of the sampling bottle, reducing the operation steps, and there is no need to operate the pressing rod 21 and the operating block 23 simultaneously, avoiding operation errors.

[0037] During the process of detecting the water content of the crude oil, the placement barrel will affect the detection of the crude oil by electromagnetic waves. As a further solution of the present invention, detection ports 30 are opened on the surfaces of the placement cylinder 6 close to the electromagnetic transmitting end 2 and the electromagnetic receiving end 3, and the detection ports 30 penetrate through the placement cylinder 6;

[0038] During the process of detecting the water content of the crude oil, when the sampling bottle is placed inside the placement barrel for detection, the electromagnetic waves will pass through the detection ports 30 on both sides of the placement barrel, reducing the influence of the placement barrel on the propagation process of the electromagnetic waves and improving the accuracy of the crude oil detection.

[0039] During the process of moving the sampling bottle into the placement barrel, the direct falling speed of the sampling bottle in the placement barrel will be relatively fast, and it will shake up and down after contacting the lifting plate 8, affecting the detection of the crude oil. As a further solution of the present invention, a plurality of equally-angled arranged sliding grooves 31 are opened on the inner wall surface of the placement cylinder 6. The depth of the upper side of the sliding groove 31 is greater than that of the lower side, and rubber rods 32 are rollingly arranged in the sliding grooves 31;

[0040] In the process of moving the sampling bottle into the placement barrel, the sampling bottle will move downward together with the rubber rod 32, and the rubber rod 32 will move back in the slide groove 31. When the rubber rod 32 moves to a shallow position at the bottom of the slide groove 31, the rubber rod 32 will partially move out of the slide groove 31 and contact the surface of the sampling bottle. The sampling bottle will slow down its downward movement speed under the action of the friction force of the rubber rod 32, avoiding a large shaking of the sampling bottle when it moves downward and contacts the lifting plate 8, thereby affecting the subsequent crude oil detection.

[0041] In the process of the clamping block 13 clamping the sampling bottle, the friction between the clamping block 13 and the sampling bottle is small, and the sampling bottle cannot be clamped well. As a further solution of the present invention, a plurality of arc-shaped friction strips 33 are fixedly connected to the surface of the clamping block 13;

[0042] When the clamping block 13 clamps the sampling bottle, the arc-shaped friction strip 33 will contact the sampling bottle, increasing the friction between the clamping block 13 and the sampling bottle, ensuring the clamping effect of the clamping block 13 on the sampling bottle, and being able to quickly slow down the speed of the sampling bottle.

[0043] In the process of taking out the sampling bottle after the detection of the water content of crude oil is completed, when the pressing rod 21 moves downward, it will drive the action block 29 to move downward together. The through hole of the pressing rod 21 and the mounting shell 1 needs to be able to allow the pressing rod 21 and the action block 29 to pass through together. The pressing rod 21 is unstable when moving downward. As a further solution of the present invention, a fixing cylinder 34 is fixedly connected to the inner wall surface of the mounting shell 1. The pressing rod 21 slides inside the fixing cylinder 34. A clearance notch 35 is opened on the surface of the fixing cylinder 34 corresponding to the position of the action block 29;

[0044] When the sampling bottle needs to be taken out after the detection of the water content of the crude oil is completed, the pressing rod 21 is pressed downward, and the pressing rod 21 moves in the fixing tube 34 , so that the pressing rod 21 can move stably, and the action block 29 moves back to the clearance gap 35 .
