Abstract
Description
A device for measuring the cloud point of an organosilicon surfactant Technical Field
[0001] This invention relates to the field of chemical sample analysis technology, specifically to a device for measuring the cloud point of organosilicon surfactants. Background Technology
[0002] Organosilicon surfactants have become a research hotspot in recent years. Their molecular structure differs from that of traditional hydrocarbon surfactants. The hydrophobic backbone of organosilicon surfactants is composed of alkylsiloxanes, which have stronger hydrophobic properties than traditional carbon chain hydrocarbon surfactants. They exhibit lower surface activity in solutions of the same concentration, and the higher bond energy of the hydrophobic group Si-O (105 kcal / mol) makes them more stable. Due to the unique advantages of organosilicon surfactants, such as low surface tension, strong emulsifying effect, good compatibility, and foaming, foam stabilizing, and inhibiting effects, as well as their non-toxicity, they have been widely used in textiles, cosmetics, plastics, machining, coatings, pharmaceuticals, and other fields. The cloud point is an important quality control indicator for surfactants, influenced by the surfactant's molecular structure and coexisting substances. Aqueous solutions of organosilicon surfactants are initially clear. As temperature increases, the hydrogen bonds of the hydrophilic groups in the sample detach from the hydrogen bonds of water, causing the two phases to become immiscible, resulting in turbidity and phase separation. With increasing temperature, the surfactant changes from complete dissolution to partial dissolution, and the solution begins to turn from clear to turbid. The temperature at which this transition occurs is the cloud point. Measuring the cloud point is crucial for determining the optimal operating temperature of the sample.
[0003] The existing cloud point measurement devices are all cumbersome in design. Most of them require the separate preparation of various cloud point test solutions, and then the samples are weighed and heated according to the proportion. The mass ratio of different cloud point test solutions is different, which makes the design cumbersome and inconvenient in process production and research.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a device for measuring the cloud point of organosilicon surfactants. Summary of the Invention
[0005] The purpose of this invention is to provide a device for measuring the cloud point of organosilicon surfactants to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for measuring the cloud point of an organosilicon surfactant, comprising a wastewater discharge component, a heating and stirring component, and a detection component. The heating and stirring component is disposed on the outer top of the wastewater discharge component, and the detection component is disposed on the outer top of the heating and stirring component. The detection component comprises a detection bottle, an air inlet pipe, an exhaust pipe, a drainage trough, a water-proof valve layer, a water inlet pipe, and a connector. The air inlet pipe is connected to the top left end of the detection bottle, and the exhaust pipe is disposed on the top right end of the detection bottle. A drainage trough is provided at the bottom of the detection bottle, and a water-proof valve layer is disposed inside the drainage trough. The water inlet pipe is connected to the outer end of the detection bottle, and a connector is disposed at the top end of the detection bottle. A magnetic rotor is disposed at the bottom inside the detection bottle.
[0007] Furthermore, the sewage discharge assembly includes a fixed base, an electrically controlled push rod, a sewage discharge seat, a connecting pipe, a sewage discharge hose, and a sewage discharge port. The electrically controlled push rod is provided in the middle of the interior of the fixed base, and the sewage discharge seat is provided at the output end of the electrically controlled push rod. The connecting pipe is connected to the top outer end of the sewage discharge seat, and the sewage discharge hose is connected to the outer end of the sewage discharge seat. The sewage discharge port is provided at the outer end of the fixed base.
[0008] Furthermore, the connecting pipe is connected to the drain hose via a drain seat, and the drain hose is connected to the drain outlet.
[0009] Furthermore, the heating and stirring assembly includes a docking base, a heating layer, a magnetic stirrer, and a through groove. The heating layer is disposed inside the docking base, and the magnetic stirrer is disposed in the middle of the docking base. The through groove is formed inside the docking base.
[0010] Furthermore, the outer contour of the test bottle matches the inner contour of the docking base, and the bottom surface of the test bottle is in contact with the top surface of the magnetic stirrer.
[0011] Furthermore, the magnetic stirrer drives the magnetic rotor to rotate, and the position and size of the through groove correspond one-to-one with the position and size of the connecting pipe.
[0012] Furthermore, the air inlet pipe, exhaust pipe, and water inlet pipe are connected to the inside of the test bottle, and the test bottle and the connector are integrated.
[0013] Furthermore, a first fixing plug is disposed inside the connector, and a transparent test tube is disposed inside the first fixing plug. A second fixing plug is disposed inside the top inner side of the transparent test tube, and a thermometer is disposed inside the second fixing plug. A piston block is disposed inside the test bottle, and a light guide layer is disposed in the middle of the piston block.
[0014] Furthermore, the electrically controlled push rod drives the connecting pipe to move upward, opening the water-proof valve layer and passing through the drainage groove, and the connecting pipe communicates with the inside of the test bottle after passing through the drainage groove.
[0015] Furthermore, the outer contour of the piston block fits against the inner wall of the test bottle, and the inner contour of the piston block fits against the outer wall of the transparent test tube.
[0016] This invention provides a device for measuring the cloud point of organosilicon surfactants, which has the following advantages:
[0017] 1. This invention utilizes a heating layer to heat the solution inside the test bottle, while a magnetic stirrer rotates the magnetic rotor, mixing the solution to ensure uniform mixing of the silicone surfactant and deionized water. When the temperature reaches the cloud point of the silicone surfactant, the solution becomes cloudy and discolored. Because the water inside the transparent test tube does not come into contact with the solution in the test bottle, the water remains clear. The inner and outer contours of the piston block fit into the transparent test tube and the test bottle, respectively, and a light guide layer is placed in the middle of the piston block. This allows the light guide layer to transmit the color of the water in the transparent test tube to the surface of the test bottle. Through this design, when the solution in the test bottle reaches the cloud point and changes color, the testing personnel or visual inspection equipment can confirm that the silicone surfactant has reached the cloud point through the obvious color difference between the light guide layer and the solution side. The thermometer inside the transparent test tube can directly record the current water temperature. This design enables the measurement of the cloud point of silicone surfactants to be highly accurate while being efficient and simple.
[0018] 2. This invention utilizes an electrically controlled push rod to move the drain seat upwards. This allows the connecting pipe to slide within the channel and enter the drainage trough. As the connecting pipe moves upwards into the drainage trough, it pushes open the water-resistant valve layer and allows it to enter the test bottle. This allows the solution from the test bottle, after testing, to be guided into the drain seat through the connecting pipe. Because the inlet pipe has a larger diameter than the connecting pipe, the inlet speed is faster than the outlet speed. During the outlet process, the tester injects clean water into the inlet pipe, filling the space inside the test bottle up to the bottom of the piston block. This clean water effectively washes away any solution that splashes during stirring. This design effectively prevents the residue of silicone surfactants in the test bottle, thus avoiding interference with subsequent tests. The wastewater entering the drain seat is discharged through the drain hose from the outlet. Through these operations, the equipment can be cleaned quickly, facilitating subsequent group-specific silicone surfactant cloud point testing. This makes the testing process highly efficient.
[0019] 3. The air inlet and exhaust pipes of this invention can be connected to an air supply pump and a suction pump, respectively. During the drainage process, the air supply pump injects high-pressure gas into the test bottle through the air inlet pipe. Under the high pressure of the gas, the piston block moves inside the test bottle. As the piston block moves and contacts the water surface, it increases the water flow rate. This improves the drainage speed after cleaning the test bottle, thus enhancing the equipment's efficiency. Furthermore, the piston block scrapes away water adhering to the inner wall of the test bottle during its movement. This design also effectively prevents the residue of silicone surfactants inside the equipment. Additionally, with the assistance of the piston block… The push mechanism effectively prevents water residue at the bottom of the test bottle, thus avoiding the problem of water not being completely drained. After drainage, the air pump operates to extract the gas inside the test bottle through the exhaust pipe. As the gas is extracted, the piston block moves upward and resets inside the test bottle due to the decrease in air pressure. During the upward and reset process, the piston block cleans the inner wall of the test bottle again. This design allows for flexible adjustment of the piston block's position. By adjusting the piston block to the same height as the volume of the test bottle and the volume of the solution to be tested, the testing personnel can quickly determine whether the solution ratio is correct after pouring in the solution, which effectively reduces the equipment's error rate.

[0027] Please refer to Figures 1 to 6. The present invention provides a technical solution: a device for measuring the cloud point of an organosilicon surfactant, comprising a drain assembly 1, a heating and stirring assembly 2, and a detection assembly 3. The heating and stirring assembly 2 is disposed on the outer top of the drain assembly 1, and the detection assembly 3 is disposed on the outer top of the heating and stirring assembly 2. The detection assembly 3 comprises a detection bottle 301, an air inlet pipe 302, an exhaust pipe 303, a drainage trough 304, a water-proof valve layer 305, a water inlet pipe 306, and a connector 307. The air inlet pipe 302 is connected to the top left end of the detection bottle 301, and the exhaust pipe 303 is disposed on the top right end of the detection bottle 301. The drainage trough 304 is opened at the bottom of the detection bottle 301, and the water-proof valve layer 305 is disposed inside the drainage trough 304. The water inlet pipe 306 is connected to the outer end of the detection bottle 301, and the connector 307 is disposed at the top end of the detection bottle 301. A magnetic rotor 4 is disposed at the bottom inside the detection bottle 301.
[0028] Please refer to Figures 1 to 6. The sewage discharge assembly 1 includes a fixed base 101, an electrically controlled push rod 102, a sewage discharge seat 103, a connecting pipe 104, a sewage discharge hose 105, and a sewage discharge port 106. The electrically controlled push rod 102 is located at the middle of the interior of the fixed base 101, and the sewage discharge seat 103 is located at the output end of the electrically controlled push rod 102. The connecting pipe 104 is connected to the top outer end of the sewage discharge seat 103, and the sewage discharge hose 105 is connected to the outer end of the sewage discharge seat 103. The sewage discharge port 106 is located at the outer end of the fixed base 101. The connecting pipe 104... 4. The drain seat 103 is connected to the drain hose 105, and the drain hose 105 is connected to the drain port 106. The heating and stirring assembly 2 includes a docking base 201, a heating layer 202, a magnetic stirrer 203, and a through groove 204. The heating layer 202 is provided inside the docking base 201, and the magnetic stirrer 203 is provided in the middle of the docking base 201. The through groove 204 is opened inside the docking base 201. The outer contour of the test bottle 301 matches the inner contour of the docking base 201, and... The bottom surface of the test bottle 301 is in contact with the top surface of the magnetic stirrer 203. The magnetic stirrer 203 drives the magnetic rotor 4 to rotate. The position and dimensions of the through groove 204 correspond one-to-one with the position and dimensions of the connecting pipe 104. The air inlet pipe 302, the exhaust pipe 303, and the water inlet pipe 306 are connected to the inside of the test bottle 301. The test bottle 301 and the connecting pipe 307 are integrated. The connecting pipe 307 has a first fixing plug 5 inside, and a transparent test tube 6 is placed inside the first fixing plug 5. The top inner side of the transparent test tube 6 is fitted with... A second fixing plug 7 is provided, and a thermometer 8 is installed inside the second fixing plug 7. A piston block 9 is provided inside the test bottle 301, and a light guide layer 10 is provided in the middle of the piston block 9. An electric control push rod 102 drives the connecting tube 104 to move upward, push open the water-proof valve layer 305 and pass through the drainage groove 304. After the connecting tube 104 passes through the drainage groove 304, it communicates with the inside of the test bottle 301. The outer contour of the piston block 9 is in contact with the inner wall of the test bottle 301, and the inner contour of the piston block 9 is in contact with the outer wall of the transparent test tube 6.
[0029] The specific operation is as follows: The tester inserts the magnetic rotor 4 into the test bottle 301, allowing it to reach the top of the bottle. Then, the operator engages the first fixing plug 5 with the connector 307, and inserts the transparent test tube 6 into the first fixing plug 5, securing it to the connector 307. The tester adjusts the height of the transparent test tube 6 within the test bottle 301 to ensure it is submerged in the solution to be tested. The test bottle 301 is made of transparent quartz, making the adjustment of the transparent test tube 6's height readily apparent. After adjustment, the tester pours water into the transparent test tube 6 and places a thermometer 8 inside. The thermometer 8 is fixed to the transparent test tube 6 using a second fixing plug 7, which ensures the stability of the fixation between the thermometer 8 and the transparent test tube 6. After the thermometer 8 is fixed and installed, the tester places the test bottle 301 on top of the docking base 201, so that the outer wall of the test bottle 301 can contact the heating layer 202 and the bottom surface can contact the magnetic stirrer 203. After the test bottle 301 is placed on top of the docking base 201, the tester mixes the organosilicon surfactant to be tested with deionized water at a ratio of 1:99, and then injects the mixed liquid into the test bottle 301 through the water inlet pipe 306. The water-proof valve layer 305 at the bottom of the test bottle 301 can prevent the solution from leaking out of the drain trough 304. At this point, the preparation work before the test is completed. During testing, the heating layer 202 heats the solution inside the test bottle 301, while the magnetic stirrer 203 rotates the magnetic rotor 4, mixing the solution to ensure uniform mixing of the silicone surfactant and deionized water. When the temperature reaches the cloud point of the silicone surfactant, the solution becomes cloudy and discolored. Because the water in the transparent test tube 6 does not come into contact with the solution in the test bottle 301, the water remains clear. The inner and outer contours of the piston block 9 fit snugly against the transparent test tube 6 and the test bottle 301, respectively. A light guide layer 10 is installed in the middle of the piston block 9, allowing the light guide layer 10 to guide the color of the water in the transparent test tube 6. The solution in the test bottle 301, when it reaches its cloud point and changes color, can be confirmed by the obvious color difference between the light guide layer 10 and the solution side, allowing the testing personnel or visual inspection equipment to verify that the silicone surfactant has reached its cloud point. Meanwhile, the thermometer 8 inside the transparent test tube 6 can directly record the current water temperature. This design ensures high accuracy while simplifying and simplifying the measurement of the silicone surfactant's cloud point. After the cloud point detection is complete, the electrically controlled push rod 102 moves the drain seat 103 upwards, allowing the connecting pipe 104 to slide inside the through groove 204 and enter the drain trough 304. As the connecting pipe 104 enters the drain trough 304 and continues to move upwards...The water-resistant valve layer 305 can be pushed open to enter the test bottle 301. This allows the solution that has been tested inside the test bottle 301 to enter the drain seat 103 through the connecting pipe 104. Because the diameter of the inlet pipe 306 is designed to be larger than that of the connecting pipe 104, the water inflow speed is faster than the drainage speed. During the drainage process, the tester can inject clean water into the inlet pipe 306 to fill the space inside the test bottle 301 up to the bottom of the piston block 9. This allows the clean water to clean up the solution that splashes higher during stirring. Through this design, the presence of silicone surfactants can be effectively avoided. Residue inside the test bottle 301 can affect subsequent tests. Wastewater entering the drain seat 103 can be discharged from the drain port 106 through the drain hose 105. Through these operations, the equipment can be cleaned quickly, facilitating subsequent group-specific cloud point testing of silicone surfactants. This makes the equipment's testing process more efficient. The air inlet pipe 302 and the exhaust pipe 303 can be connected to an air supply pump and a suction pump, respectively. During the drainage process, the air supply pump operates, injecting high-pressure gas into the test bottle 301 through the air inlet pipe 302. Under the high pressure of the gas, the piston block 9 is driven. The piston block 9 moves inside the test bottle 301, and during this movement, it comes into contact with the water surface, increasing the water flow rate. This improves the drainage speed after cleaning the test bottle 301, thereby enhancing the equipment's efficiency. Furthermore, the piston block 9 scrapes away water adhering to the inner wall of the test bottle 301 during its movement. This design effectively prevents the residue of silicone surfactants within the equipment. Additionally, the downward push of the piston block 9 effectively prevents water residue at the bottom of the test bottle 301, thus avoiding the problem of incomplete drainage. After the water is poured, the air pump operates, drawing the gas out of the test bottle 301 through the exhaust pipe 303. As the gas is removed, the piston block 9 moves upward and resets inside the test bottle 301 due to the reduced air pressure. During this resetting process, the piston block 9 cleans the inner wall of the test bottle 301 again. This design allows for flexible adjustment of the piston block 9's position. By adjusting the piston block 9 to the same height as the volume of the test bottle 301 and the solution to be tested, the testing personnel can quickly determine whether the solution ratio is correct after pouring in the solution, effectively reducing the equipment's error rate.
[0030] In summary, when using this organosilicon surfactant cloud point measuring device, the operator first places the magnetic rotor 4 inside the test bottle 301, allowing the magnetic rotor 4 to reach the top of the test bottle 301. Then, the operator engages the first fixing plug 5 with the connector 307 and inserts the transparent test tube 6 into the first fixing plug 5, securing the transparent test tube 6 to the connector 307. The operator then adjusts the height of the transparent test tube 6 inside the test bottle 301 to ensure that the transparent test tube 6 is submerged in the solution to be tested. The test bottle 301 is made of transparent quartz material, which makes the adjustment of the height of the transparent test tube 6 inside the test bottle 301 quite intuitive.
[0031] After the transparent test tube 6 is adjusted to the correct height, the tester fills the transparent test tube 6 with clean water and places the thermometer 8 inside the transparent test tube 6. The thermometer 8 is fixed to the transparent test tube 6 using the second fixing plug 7, which ensures the stability of the fixation between the thermometer 8 and the transparent test tube 6. After the thermometer 8 is fixed and installed, the tester places the test bottle 301 on the top of the docking base 201, so that the outer wall of the test bottle 301 can contact the heating layer 202 and the bottom surface can contact the magnetic stirrer 203. After the test bottle 301 is placed on the top of the docking base 201, the tester mixes the organosilicon surfactant to be tested with deionized water at a ratio of 1:99, and then injects the mixed liquid into the test bottle 301 through the water inlet pipe 306. The water-proof valve layer 305 at the bottom of the test bottle 301 can prevent the solution from leaking out of the drain trough 304. At this point, the preparation work before the test is completed.
[0032] Next, the heating layer 202 heats the solution inside the test bottle 301, while the magnetic stirrer 203 rotates the magnetic rotor 4. During rotation, the magnetic rotor 4 mixes the solution, ensuring a uniform mixture of the silicone surfactant and deionized water. When the temperature rises to the cloud point of the silicone surfactant, the solution becomes cloudy and discolored. Because the water inside the transparent test tube 6 does not come into contact with the solution in the test bottle 301, the water remains clear. The inner and outer contours of the piston block 9 are respectively aligned with the transparent test tube 6 and... The test bottle 301 is fitted together, and a light guide layer 10 is placed in the middle of the piston block 9. This allows the light guide layer 10 to guide the color of the clear water in the transparent test tube 6 to the surface of the test bottle 301. With the above design, when the solution in the test bottle 301 reaches the turbidity point and changes color, the tester or visual inspection equipment can confirm that the organosilicon surfactant has reached the turbidity point through the obvious color difference between the end of the light guide layer 10 and the solution side. The thermometer 8 in the transparent test tube 6 can intuitively record the current water temperature. Through this design, the measurement of the turbidity point of organosilicon surfactant can be made efficient and simple while ensuring high accuracy.
[0033] Subsequently, after the cloud point detection of the silicone surfactant is completed, the electrically controlled push rod 102 operates, causing the drain seat 103 to move upward. This allows the connecting pipe 104 to slide inside the through groove 204 and enter the drain trough 304. As the connecting pipe 104 enters the drain trough 304 and continues to move upward, it pushes open the water-proof valve layer 305 and allows it to enter the test bottle 301. This allows the solution that has been tested inside the test bottle 301 to enter the drain seat 103 through the guide of the connecting pipe 104. Because the diameter of the inlet pipe 306 is designed to be larger than that of the connecting pipe 104, the inlet speed is faster than the outlet speed. During the drainage process, the tester injects clean water into the inlet pipe 306, filling the space inside the test bottle 301 up to the bottom of the piston block 9. This allows the clean water to clean up the solution that splashes during stirring. This design effectively avoids the residue of silicone surfactants in the test bottle 301, which could affect subsequent tests. Wastewater entering the drain seat 103 can be discharged from the drain port 106 through the drain hose 105. Through the above operations, the equipment can be cleaned quickly, which facilitates the subsequent group of silicone surfactant cloud point detection, making the equipment's testing process more efficient.
[0034] Finally, during the drainage process, the air pump injects high-pressure gas into the test bottle 301 through the air inlet pipe 302. Under the pressure of the gas, the piston block 9 moves inside the test bottle 301. As the piston block 9 contacts the water surface during this movement, it increases the water flow rate. This improves the drainage speed after cleaning the test bottle 301, further enhancing the equipment's efficiency. Furthermore, the piston block 9 scrapes away water adhering to the inner wall of the test bottle 301 during its movement. This design effectively prevents the residue of silicone surfactants within the equipment. Additionally, the downward push of the piston block 9 effectively prevents water from splashing into the test bottle 301. The residue at the bottom effectively prevents water from remaining in the test bottle 301. After drainage, the air pump operates to extract the gas inside the test bottle 301 through the exhaust pipe 303. When the gas inside the test bottle 301 is extracted, the piston block 9 moves upward and resets inside the test bottle 301 due to the decrease in air pressure. During the upward and reset process, the piston block 9 can clean the inner wall of the test bottle 301 again. This design allows for flexible adjustment of the position and height of the piston block 9. By adjusting the piston block 9 to the same height as the volume of the test bottle 301 and the volume of the solution to be tested, the testing personnel can quickly determine whether the solution ratio is correct after pouring in the solution to be tested, which can effectively reduce the error rate of the equipment.
