Description

Technical Field

[0001] This invention relates to the field of chemical product testing equipment, specifically a device for testing the water miscibility of liquid organic chemical products. The device aims to provide an accurate and efficient means of testing the solubility of liquid organic chemical products when mixed with water, providing reliable technical support for the research, development, production, and quality control of chemical products. Background Technology

[0002] With the rapid development of the chemical industry, liquid organic chemical products are increasingly widely used in various fields. When these products are mixed with water, their water miscibility becomes a crucial factor affecting product performance. Therefore, water miscibility testing of liquid organic chemical products is of great significance for ensuring product quality and optimizing product formulations. However, traditional testing methods often rely on manual observation and judgment, which are highly subjective and make it difficult to guarantee the accuracy and consistency of test results. To address these issues, this invention provides a water miscibility testing device for liquid organic chemical products. This device automates, refines, and optimizes the testing process, adapting to the testing needs of liquid organic chemical products with different properties, and providing strong technical support for the development of the chemical industry. Summary of the Invention

[0003] The present invention addresses the aforementioned deficiencies in the prior art by providing a water miscibility testing device for liquid organic chemical products, comprising a cross slide, a support, an electromagnet, a colorimetric camera, an industrial control computer, and a constant temperature light chamber. The constant temperature light chamber includes: an insulation box, a colorimetric tube support, a colorimetric tube iron cover, a semiconductor cooling chip, an LED light source, a temperature controller, and a colorimetric tube.

[0004] The inner wall of the insulated box is coated with a black layer to effectively absorb ambient light, minimizing light reflection and interference, and ensuring the accuracy and stability of the colorimetric process. A colorimetric tube holder is installed at the bottom of the insulated box to hold two colorimetric tubes of the same specifications and material, serving as the sample detection colorimetric tube and the pure water control colorimetric tube, respectively. Furthermore, an LED light source is installed inside the insulated box. The light emitted by this LED light source passes radially through the colorimetric tubes, ensuring that the light uniformly and stably illuminates the liquid in the colorimetric tubes, providing clear and accurate image information to the colorimetric camera.

[0005] Furthermore, the temperature controller display screen is installed outside the insulation box, while the temperature control probe is inserted inside the insulation box, ensuring that the test personnel can monitor the temperature inside the insulation box in real time.

[0006] Furthermore, each side of the insulated box is equipped with a thermoelectric cooler. The power supply of the thermoelectric cooler is connected to a temperature controller. When the temperature inside the box is higher than 20 degrees Celsius, the temperature controller turns on the power supply of the thermoelectric cooler, and the thermoelectric cooler begins to cool. When the temperature inside the box is lower than 20 degrees Celsius, the temperature controller disconnects the power supply of the thermoelectric cooler, and the thermoelectric cooler stops cooling. The temperature inside the insulated box is regulated by the cooperation of the temperature controller and the thermoelectric cooler to ensure that the temperature inside the box is maintained at a constant 20±1 degrees Celsius, providing an ideal temperature environment for water miscibility testing.

[0007] Furthermore, the main body of the colorimetric tube cap is made of nylon, and a 3-millimeter-thick iron disc is embedded at the top. When the electromagnet is energized, the colorimetric tube cap can be tightly attracted to the electromagnet, and when the electromagnet is de-energized, the attracted cap can be released.

[0008] Furthermore, the electromagnet and colorimeter camera are both mounted on a bracket, which is mounted on a cross slide. The cross slide can be used to move linearly along the X-axis or Y-axis to bring the electromagnet and colorimeter camera to a designated position.

[0009] Furthermore, the industrial control computer is integrated with the constant temperature light chamber, cross slide, electromagnet, and colorimetric camera, enabling it to not only flexibly control one or more devices and components, but also to accurately analyze the images of the sample solution and pure water captured by the colorimetric camera, calculate the absorbance value and compare it, thereby inferring the water solubility of the sample solution.

[0010] Compared with existing technologies, this invention automates, refines, and improves the efficiency of the testing process, adapting to the testing needs of liquid organic chemical products with different properties, and providing reliable technical support for the research, development, production, and quality control of chemical products.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. The present invention is not limited to the specific embodiments disclosed below.

[0016] Please see Figure 1 The present invention provides a water miscibility testing device for liquid organic chemical products, comprising: 1. a cross slide, 2. a support, 3. an electromagnet, 4. a colorimetric camera, 5. a constant temperature light chamber, 6. a colorimetric tube cap, and 7. an industrial control computer.

[0017] Please see Figure 2In this process, when it is necessary to test the water miscibility of the sample, the experimenter first removes the sample detection colorimetric tube 55 and the pure water control colorimetric tube 56 from the constant temperature light chamber 5. Then, the temperature controller 53 and the semiconductor cooling chip 52 are activated. Through the cooling effect of the temperature controller 53 and the semiconductor cooling chip 52, as well as the heat preservation effect of the heat preservation chamber 50, the temperature inside the constant temperature light chamber 5 is maintained at 20±1 degrees Celsius. Subsequently, the experimenter measures a certain volume of sample according to a predetermined ratio and injects it into a clean, dry container. Slowly add water to the 100ml mark in the sample detection colorimetric tube 55, tighten the metal cap 6, shake thoroughly and let stand until all air bubbles disappear. Then, measure 100ml of purified water and inject it into a clean, dry pure water control colorimetric tube 56. Next, the experimenter places the pure water control colorimetric tube 56 and the sample detection colorimetric tube 55 (with the metal cap 6) together into the constant temperature light chamber 5, fixes them with the colorimetric tube holder 51, and lets them stand for 30 minutes. After 30 minutes, open L... The light emitted by the LED light source 54 passes radially through the pure water control colorimetric tube 56 and the sample detection colorimetric tube 55, ensuring that the light shines evenly and stably on the liquid in the tube, providing clear and accurate image information to the colorimetric camera 4. Subsequently, the cross slide 1 is used to move the support 2 along the X-axis to the designated position, so that the electromagnet 3 and the colorimetric camera 4 mounted on the support 2 are respectively aligned with the colorimetric tube cap 6 covering the sample detection colorimetric tube 55 and the opening of the unsealed pure water control colorimetric tube 56. Then, the cross slide 1 is used to lower the electromagnet 3 and the colorimetric camera 4 along the Y-axis to the designated position. While the electromagnet 3 is energized and attracts the colorimetric tube cap 6, the colorimetric camera 4 takes a picture of the pure water in the pure water control colorimetric tube 56, obtains the color image of the pure water in the pure water control colorimetric tube 56, and transmits the obtained image to the industrial control computer 7. The industrial control computer 7 extracts the values ​​of the red, green, and blue color models from the image and calculates the absorbance of the pure water in the pure water control colorimetric tube 56. Subsequently, the colorimetric camera 4 is moved along the X and Y axes at specified directions and distances using the cross slide 1, bringing it to the opening of the sample detection colorimetric tube 55. The camera then captures an image of the sample solution in the tube, acquiring a color image of the solution. This image is transmitted to the industrial control computer 7, which extracts the values ​​of the red, green, and blue color models from the image and calculates the absorbance of the sample solution in the tube based on the Lambert-Bipolar distribution. According to Engel's Law, the absorbance of a solution is directly proportional to its concentration. By measuring the absorbance of the sample solution in the sample detection colorimetric tube 55 and the pure water in the pure water control colorimetric tube 56, the transparency of the sample solution and the pure water can be inferred respectively. Finally, by comparing the absorbance of the sample solution and the pure water, the water miscibility of the sample can be determined. If the absorbance of the sample solution is close to that of the pure water, it indicates that its water miscibility is good. Conversely, if the absorbance of the sample solution differs greatly from that of the pure water, it indicates that its water miscibility is poor.
