Description

Technical Field

[0001] This utility model relates to the field of monitoring instrument technology, and in particular to a perfluorobetaine low-temperature antifreeze stability monitoring instrument. Background Technology

[0002] Perfluorobetaine is a fluorinated amphoteric surfactant whose molecular structure contains both perfluoroalkyl chains and betaine-type hydrophilic groups. It exhibits excellent surface activity, chemical stability, and environmental compatibility, and is widely used in fire-fighting foams, industrial coatings, and oil extraction. In low-temperature applications, its freeze-thaw stability directly affects product performance. Especially during storage and transportation in cold regions or in cold chain logistics, precise monitoring of its phase changes and physical property stability under dynamic low-temperature environments is essential.

[0003] In existing technologies, the detection of low-temperature stability of perfluorobetaine generally lacks simulation of mechanical vibration interference in real low-temperature transportation environments, which makes it difficult for existing detection methods to accurately reflect the actual antifreeze performance of perfluorobetaine under complex working conditions, and has certain shortcomings. To address this, we propose a low-temperature antifreeze stability monitoring instrument for perfluorobetaine. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention, through the synergistic effect of a vibration mechanism and a semiconductor cooling array, realistically simulates the dual operating conditions of dynamic mechanical vibration and temperature changes in a cryogenic transportation environment, enabling multi-dimensional real-time monitoring of the freeze-thaw stability of perfluorobetaine samples. By incorporating an adjustable monitoring probe mechanism, it achieves non-contact detection coverage of different sample positions and angles, ensuring accurate and complete data acquisition across the entire spatial domain.

The vibration mechanism 5 includes a first housing 51 fixed to the inner bottom of the housing 2, a first motor 52 mounted on the inner bottom of the first housing 51, an eccentric wheel 53 mounted on the output shaft of the first motor 52, and movable rods 54 mounted on both sides of the first housing 51, the movable rods 54 being inserted into the inner... The unit is connected to a movable plate 55, and wheel grooves 56 are installed on the side of the movable plate 55. Movable frames 57 are fixed to the top of the two movable rods 54. Support springs 58 are installed between the movable frames 57 and the first housing 51. The eccentric wheel 53 is rotatably connected to the wheel grooves 56 on both sides. The support springs 58 are sleeved on the movable rods 54. The placement frame 6 is fixed on the movable frame 57. An adjustment mechanism 7 is installed on the inner wall of the housing 2. A monitoring probe 8 is installed inside the adjustment mechanism 7. The adjustment mechanism 7 includes a fixed frame 71 fixed to the side wall of the housing 2. A threaded column 72 is fixed inside the fixed frame 71. A screw thread is connected to the threaded column 72. A threaded sleeve 73 is connected to the second housing 75. A first bevel gear 74 is fixedly sleeved on the threaded sleeve 73. A second housing 75 is rotatably connected to the threaded sleeve 73. A second motor 76 is mounted on the side of the second housing 75. The output shaft of the second motor 76 is inserted into the interior of the second housing 75 and connected to a second bevel gear 77. A mounting bracket 78 is mounted on the side of the second housing 75. A third motor 79 is mounted on the side of the mounting bracket 78. The output shaft of the third motor 79 is inserted into the interior of the mounting bracket 78 and fixed to the monitoring probe 8. The second housing 75 and the mounting bracket 71 are slidably connected. The first bevel gear 74 and the second bevel gear 77 are meshed. This invention, through the synergistic effect of a vibration mechanism and a semiconductor cooling array, realistically simulates the dual operating conditions of dynamic mechanical vibration and temperature changes in a cryogenic transportation environment, enabling multi-dimensional real-time monitoring of the freeze-thaw stability of perfluorobetaine samples. The adjustable monitoring probe mechanism achieves non-contact detection coverage at different positions and angles of the sample, ensuring accurate and complete data acquisition across the entire spatial domain. Furthermore, the zoned temperature control structure of the semiconductor cooling array achieves uniform temperature distribution and gradient regulation within the chamber, enabling precise reproduction and stable maintenance of complex cryogenic environments. This invention effectively solves the shortcomings of traditional detection methods in simulating actual transportation vibration interference, significantly improving the accuracy and reliability of freeze-thaw stability assessment.

[0020] When the equipment is started, the semiconductor cooling array 4 begins to work, cooling the interior of the chamber 2 to the set low temperature value through the PID temperature control system. In the vibration mechanism 5 located at the bottom of the chamber 2, the first motor 52 drives the eccentric wheel 53 to rotate, which, through contact with the wheel groove 56, pushes the movable plates 55 on both sides to reciprocate, causing the movable rod 54 and the movable frame 57 to generate periodic vertical vibration. The sample container on the placement rack 6 then generates low-frequency vibration simulating transportation vibration. The support spring 58 provides buffering and maintains amplitude stability during vibration. When the adjustment mechanism 7 is running, the second motor 76 drives the second bevel gear 77 to mesh with the first bevel gear 74, driving the threaded sleeve 73 to rise and fall along the threaded post 72, realizing the vertical displacement adjustment of the second housing 75 and the monitoring probe 8. The third motor 79 drives the monitoring probe 8 to adjust the pitch angle. The monitoring probe 8 can scan the sample state from multiple angles and automatically record the phase change characteristic parameters of the sample under the vibration-low temperature coupling effect.

[0021] In summary, compared to existing technologies, this invention, through the synergistic effect of a vibration mechanism and a semiconductor cooling array, achieves a realistic simulation of the dual working conditions of dynamic mechanical vibration and temperature changes in a low-temperature transportation environment, enabling multi-dimensional real-time monitoring of the freeze-thaw stability of perfluorobetaine samples. By setting up an adjustable monitoring probe adjustment mechanism, it achieves non-contact detection coverage of different positions and angles of the sample, realizing the accuracy and completeness of data acquisition across the entire spatial domain. Furthermore, by setting up a zoned temperature control structure for the semiconductor cooling array, it achieves uniform distribution and gradient control of the temperature field within the chamber, enabling accurate reproduction and stable maintenance of complex low-temperature environments. This invention effectively solves the shortcomings of traditional detection methods in simulating actual transportation vibration interference, significantly improving the accuracy and reliability of freeze-thaw stability assessment.
