Description

Technical Field

[0001] This utility model relates to the field of microemulsion emulsification technology, and in particular to a microemulsion emulsification stability testing device. Background Technology

[0002] As a transparent and stable dispersion system formed by oil phase, aqueous phase, surfactant and co-surfactant, the emulsification stability of microemulsions is a core indicator of product quality. When researching and developing new microemulsions, stability measurement equipment is crucial, as it can help monitor the physical and chemical stability of microemulsions under different conditions.

[0003] Existing microemulsion stability testing methods only allow sampling after emulsification, making it difficult to test microemulsions with different stirring times. The test results lack a control, and both sample preparation and data recording rely on manual operation, making it difficult to achieve batch testing and real-time monitoring. Therefore, we propose a microemulsion emulsification stability testing device. Utility Model Content

[0030] The microemulsion stability sampling and testing assembly 1 includes a rotating shaft 11, a first motor 12, a first drive shaft 13, a transmission gear 14, and a mounting plate 15. The rotating shaft 11 is rotatably mounted on the top of the mounting box 3. The first motor 12 is fixedly mounted on the top inner wall of the mounting frame 6.

[0031] In this embodiment, a water storage tank 7 is fixedly installed on the rear side of the fixing frame 4, and a detection device flushing assembly 2 is provided on the water storage tank 7, the centrifugal emulsifying tank 5 and the mounting box 3.

[0032] In this embodiment, the microemulsion stability sampling and testing component 1 further includes a placement tank 16, a sampling dish 17, a sampling and feeding pipe 18, and a solenoid valve 19. Multiple placement tanks 16 are located on the top of the mounting plate 15, the sampling dish 17 is located inside the placement tank 16, multiple sampling and feeding pipes 18 are fixedly installed at the bottom of the centrifugal emulsification tank 5, and the solenoid valve 19 is fixedly installed outside the sampling and feeding pipes 18. The microemulsion is adjusted into the centrifugal emulsification tank 5 for stirring and emulsification, and multiple sampling dishes 17 are placed above the placement tank 16. The solenoid valve 19 above the multiple sampling and feeding pipes 18 is controlled to open at different times, so that the microemulsion stirred inside the centrifugal emulsification tank 5 for different times can fall into the sampling dish 17 for sampling.

[0033] In this embodiment, the microemulsion stability sampling and detection component 1 further includes a fixing plate 20, a laser particle size analyzer 21, a high-speed camera 22, and a photometer 23. The fixing plate 20 is fixedly installed on the top of the rotating shaft 11, and the laser particle size analyzer 21, the high-speed camera 22, and the photometer 23 are all fixedly installed on one side of the fixing plate 20. After sampling is completed, the first motor 12 can be controlled to drive the first drive shaft 13 to rotate. The first drive shaft 13 can drive the rotating shaft 11 and the fixing plate 20 to rotate through the transmission gear 14. The fixing plate 20 can drive multiple laser particle size analyzers to rotate. The rotating angles of instrument 21, high-speed camera 22, and photometer 23 allow for the detection of microemulsions inside sampling dishes 17 at different locations. The laser particle size analyzer 21, employing the Malvern laser scattering principle, can monitor the microemulsion particle size distribution in real time. The high-speed camera 22 captures droplet morphology and observes the oil-water interfacial tension with high accuracy. The photometer 23 monitors changes in emulsion transmittance to detect flocculation trends. The laser particle size analyzer 21, high-speed camera 22, and photometer 23 are all existing technologies that can detect the stability of microemulsions, so they are not described in detail in this paper.

[0034] In this embodiment, the flushing assembly 2 of the detection device includes a second motor 24, a second drive shaft 25 and a filter screen 26. The second motor 24 is fixedly installed on the front side of the mounting box 3, the second drive shaft 25 is fixedly installed on the output end of the second motor 24, and the filter screen 26 is fixedly installed on the inner side of the second drive shaft 25.

[0035] In this embodiment, the flushing assembly 2 of the detection device also includes a water pump 27 and a flushing pipe 28. The water pump 27 is fixedly installed on the top of the water storage tank 7, and the suction end of the water pump 27 is connected to the water storage tank 7. One end of the flushing pipe 28 is fixedly installed on the output end of the water pump 27, and the other end of the flushing pipe 28 is fixedly installed on the top of the centrifugal emulsifying tank 5. By controlling the water pump 27 to draw water from the inside of the water storage tank 7 and flushing the centrifugal emulsifying tank 5 and the filter screen 26 through the flushing pipe 28, the device can be cleaned manually during batch testing, thereby greatly improving work efficiency.

[0036] In this embodiment, the top of the mounting box 3 is provided with a through hole, and the rotating shaft 11 is rotatably installed inside the through hole; the through hole facilitates the discharge of microemulsion and allows the water after rinsing to drain out. The rotating shaft 11 rotates inside the through hole, allowing the laser particle size analyzer 21, high-speed camera 22 and photometer 23 above the rotating shaft 11 to rotate and detect the microemulsion inside multiple sampling dishes 17.

[0037] In this embodiment, a drain trough is provided at the bottom of the installation box 3, and a drain pipe is provided on the inner side of the drain trough; the drain trough allows the discharged microemulsion and cleaning water to be discharged from the drain pipe, which facilitates better cleaning and drainage of the detection device.

[0038] The specific operation involves adjusting the microemulsion into the centrifugal emulsification tank 5 for stirring and emulsification, placing multiple sampling dishes 17 above the placement tank 16, and controlling the solenoid valves 19 above the multiple sampling and feeding pipes 18 to open at different times, allowing the microemulsion stirred for different times inside the centrifugal emulsification tank 5 to fall into the sampling dishes 17 for sampling. After sampling, the first motor 12 can be controlled to drive the first drive shaft 13 to rotate. The first drive shaft 13 can drive the rotating shaft 11 and the fixed plate 20 to rotate through the transmission gear 14. The fixed plate 20 can drive multiple laser particle size analyzers 21, high-speed cameras 22, and photometers 23 to rotate at different angles, allowing for the detection of microemulsion inside the sampling dishes 17 at different positions. The laser particle size analyzer 21 uses the Malvern laser scattering principle to monitor the microemulsion particle size distribution in real time. The high-speed camera 22 captures droplet morphology and observes the oil-water interfacial tension with high accuracy. The photometer 23 monitors changes in emulsion transmittance to monitor flocculation trends. Instrument 21, high-speed camera 22, and photometer 23 are all existing technologies that can detect the stability of microemulsions, so they are not described in detail here. After the test is completed, the sampling dish 17 can be collected for sample storage. At this time, the microemulsion inside the centrifugal emulsification tank 5 can be discharged through the sampling and feeding pipe 18 in the middle of the bottom, and the filter screen 26 can filter the microemulsion. The high-speed camera 22 can capture the impurities above the filter screen 26, enabling the device to detect the finished effect of the microemulsion. This makes the device have a wide detection range and does not require manual operation by personnel. It can also achieve batch detection and real-time detection. At this time, the second motor 24 is controlled to drive the second drive shaft 25 and the filter screen 26 to rotate, and the water pump 27 is controlled to draw water from the water tank 7 and flush the centrifugal emulsification tank 5 and the filter screen 26 through the flushing pipe 28. This allows the device to be cleaned manually during batch testing, thereby greatly improving work efficiency.
