Description

Technical Field

[0001] This utility model relates to the field of oscillation device technology, and in particular to a water bath oscillation device for evaluating oilfield demulsifiers. Background Technology

[0002] Currently, to ensure thorough mixing of demulsifiers and crude oil, a handheld manual shaking box is typically used. However, prolonged operation can lead to fatigue among personnel, resulting in reduced shaking force and frequency. Simultaneously, the crude oil temperature gradually decreases during shaking, increasing its viscosity and hindering complete and uniform mixing with the agent, thus affecting the agent's evaluation results. Therefore, production plants typically install water bath shaking devices specifically for oilfield demulsifiers.

[0003] In the water bath oscillation device for oilfield demulsifiers, temperature fluctuations can affect the accuracy of experimental results because the performance of demulsifiers is closely related to temperature. The demulsification effect of demulsifiers may vary at different temperatures. When used in water with a high mineral content, calcium and magnesium ions in the water may form a scale layer on the probe surface of the temperature sensor, increasing the thermal resistance of heat transfer, slowing down the response speed, and reducing the accuracy of the evaluation. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the background technology that, when used in water containing a high amount of minerals, calcium and magnesium ions in the water may form a scale layer on the probe surface of the temperature sensor, increasing the thermal resistance of heat transfer, slowing down the response speed, and reducing the accuracy of evaluation. The invention proposes a water bath oscillation device for evaluating oilfield demulsifiers.

[0031] Example

[0032] like Figure 1 and Figure 2 As shown, the present invention proposes a water bath oscillation device for evaluating oilfield demulsifiers, comprising a housing 1, a vibration chamber 2, a water bath chamber 4, and a temperature sensor 6, and also includes an oscillation groove 3 disposed on the vibration chamber 2. The water bath chamber 4 is formed inside the oscillation groove 3, and the vibration chamber 2 is formed on the housing 1. The temperature sensor 6 is disposed on the outside of the oscillation groove 3. A fixing frame 5 is fixedly installed on one side of the top of the housing 1. The housing 1 contains a heating module and a control module (not shown in the figure), and the oscillation groove 3 is connected to the control module. As this is prior art, it will not be described in detail here.

[0033] like Figure 1 - Figure 3 As shown, the device also includes a fixing component, which is installed inside the water bath chamber 4 for sample fixing. The fixing component includes a fixing platform 22 installed on the bottom wall of the water bath chamber 4. A connecting block 23 is fixedly connected to one side of the inner wall of the fixing platform 22. A placement groove 24 is opened on the connecting block 23. Two movable rods 25 slide through one side of the fixing platform 22. A fixing sleeve 26 is fixedly connected to one end of the movable rod 25. The placement groove 24 is semi-arc-shaped to facilitate the placement of round reagent bottles. The reagent bottle is placed in the placement groove 24, and the movable rod 25 is pressed in so that the fixing sleeve 26 fixes the upper and lower ends of the reagent bottle, thus completing the fixing of the reagent bottle.

[0034] It is worth noting that the two ends of the fixing sleeve 26 are fixedly connected to the limiting plates, and the limiting plates are fixedly connected to the locking blocks 27. The connecting blocks 23 are located on both sides of the placement groove 24 and have locking slots that match the locking blocks 27. While the fixing sleeve 26 fixes the reagent bottle, the locking blocks 27 are also locked into the locking slots, further enhancing the fixing effect on the reagent bottle.

[0035] like Figure 2 - Figure 5 As shown, the device also includes a cleaning device, which is mounted on the fixed frame 5 for automatic cleaning of the surface of the temperature sensor 6. The cleaning device includes a slide groove 8 on the fixed frame 5, a slider 9 is slidably installed in the slide groove 8, an L-shaped support plate 10 is fixedly connected to the slider 9, an electric telescopic rod 11 is fixedly installed on the L-shaped support plate 10, and a cleaning tank 13 is fixedly connected to the output end of the electric telescopic rod 11. By sliding the slider 9 in conjunction with extending the electric telescopic rod 11, the position of the cleaning tank 13 can be adjusted so that the cleaning tank 13 moves to the front of the temperature sensor 6.

[0036] Furthermore, a rotating shaft 15 is rotatably installed between the inner walls of the cleaning tank 13. Several soft brushes 16 are provided on the curved surface of the rotating shaft 15. A motor cover 14 is installed on one side of the cleaning tank 13. A motor is installed inside the motor cover 14. The output shaft of the motor is fixedly connected to the rotating shaft 15. The rotation of the rotating shaft 15 drives the soft brushes 16 to rotate, so that the soft brushes 16 can rotate and rub to clean the dirt layer attached to the surface of the temperature sensor 6. The soft brushes 16 have a certain degree of softness to avoid damaging the temperature sensor 6 during the rotation cleaning process.

[0037] Furthermore, a lead screw 12, which is threadedly connected to the slider 9, is rotatably installed inside the chute 8. A drive motor 7 is fixedly installed on one side of the fixed frame 5. The output shaft of the drive motor 7 is fixedly connected to the lead screw 12. When the drive motor 7 is started, the lead screw 12 rotates, and the slider 9 drives the cleaning tank 13 to move back and forth along the direction of the chute 8.

[0038] It is worth noting that a liquid storage box 17 is provided on one side of the top of the cleaning tank 13, a pressure pump 18 is installed on one side of the liquid storage box 17, and an output pipe 19 connected to the output end of the pressure pump 18 is fixedly installed on one side of the liquid storage box 17. A rectangular groove is opened on one side of the cleaning tank 13, and a mounting base 20 is fixedly installed on the bottom edge of the rectangular groove on one side of the cleaning tank 13. A guide plate 21 is rotatably installed on the mounting base 20. The size of the guide plate 21 matches the rectangular groove. A rotating rod for driving the guide plate 21 to rotate is provided inside the mounting base 20. The rotation of the guide plate 21 can seal the back side of the cleaning tank 13, and the pressure pump 18 can also make the cleaning agent sprayed from the output pipe 19 and move along the guide plate 21 into the cleaning tank 13. With the rotation of the soft brush 16, the soft brush 16 can be self-cleaned.

[0039] The working principle of this embodiment is as follows: After each evaluation experiment, the drive motor 7 is started, causing the lead screw 12 to rotate. The slider 9 can drive the L-shaped support plate 10 to move along the direction of the slide groove 8 towards the temperature sensor 6. At this time, the electric telescopic rod 11 extends and drives the cleaning tank 13 to move down and move, so that the cleaning tank 13 moves to the opposite side of the temperature sensor 6. At this time, the rotation of the rotating shaft 15 drives the soft brush 16 to rotate and rub to clean the scale layer attached to the surface of the temperature sensor 6. This avoids the scale layer increasing the thermal resistance of heat transfer, which slows down the response speed and improves the detection accuracy. The rotation of the guide plate 21 can open one side of the cleaning tank 13. The pressure pump 18 makes the cleaning agent sprayed from the output pipe 19 and flow into the cleaning tank 13 along the guide plate 21. With the rotation of the soft brush 16, the soft brush 16 is self-cleaned, which improves the subsequent cleaning effect of the soft brush 16.

[0040] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
