Description

Technical Field

[0001] The invention relates to the technical field of chemical sample analysis, in particular to a cloud point measuring device for an organosilicon surfactant. Background Art

[0002] Silicone surfactants have been a research hotspot in recent years. Their molecular structure is different from traditional general hydrocarbon surfactants. The hydrophobic main chain of silicone surfactants is composed of alkyl siloxanes. Their hydrophobic properties are stronger than those of traditional carbon chain hydrocarbon surfactants. They show lower surface activity in solutions of the same concentration, and the higher hydrophobic group Si-O bond energy (105kcal / mol) makes them more stable. Due to the unique advantages of silicone surfactants, such as low surface tension, strong emulsification effect, good compatibility, foaming, foam stabilization and inhibition effects, and non-toxicity, they have been widely used in textiles, cosmetics, plastics, mechanical processing, coatings, medicine and other fields. The turbidity point is an important quality control indicator of surfactants. It is affected by the molecular structure of the surfactant and coexisting substances. The aqueous solution of silicone surfactants is clear. As the temperature rises, the hydrogen bonds of the hydrophilic groups in the sample are separated from the hydrogen bonds of water, causing the two phases to be immiscible, and the solution becomes turbid and phase separation occurs. As the temperature rises, the surfactant changes from completely dissolved to partially dissolved, and the solution changes from clear to turbid. The temperature at the time of the transition is the turbidity point. Measuring the turbidity point is crucial to determining the optimal operating temperature of the sample to be tested.

[0003] The designs of the turbidity point measuring devices disclosed in the prior art are relatively complicated. Most of them require the separate preparation of various turbidity point test solutions, and then the samples are weighed in proportion for heating. Different turbidity point test solutions have different mass ratios, and the designs are relatively complicated, which is inconvenient in process production research.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a turbidity point measuring device for silicone surfactant is proposed. Summary of the invention

[0007] Furthermore, the sewage discharge assembly includes a fixed seat, an electric control push rod, a sewage discharge seat, a docking tube, a sewage discharge hose and a sewage discharge port. The inner middle end of the fixed seat is provided with an electric control push rod, and the output end of the electric control push rod is provided with a sewage discharge seat. The top outer end of the sewage discharge seat is connected with a docking tube, and the outer end of the sewage discharge seat is connected with a sewage discharge hose, and the outer end of the fixed seat is provided with a sewage discharge port.

[0008] Furthermore, the butt joint is connected to a sewage hose through a sewage seat, and the sewage hose is connected to a sewage outlet.

[0009] Furthermore, the heating and stirring assembly includes a docking base, a heating layer, a magnetic stirrer and a through groove. The docking base is provided with a heating layer inside, and a magnetic stirrer is provided at the middle end inside the docking base. The docking base is provided with a through groove inside.

[0010] Furthermore, the outer contour of the detection bottle matches the inner contour of the docking base, and the bottom surface of the detection bottle fits the top surface of the magnetic stirrer.

[0011] Furthermore, the magnetic stirrer drives the magnetic rotor to rotate, and the position size of the through groove corresponds to the position size of the butt joint pipe.

[0012] Furthermore, the air inlet pipe, the exhaust pipe, the water inlet pipe are connected to the interior of the detection bottle, and the detection bottle and the docking joint are integrated.

[0013] Furthermore, a first fixed plug is disposed inside the docking joint, and a transparent test tube is disposed inside the first fixed plug, a second fixed plug is disposed on the inner side of the top of the transparent test tube, and a thermometer is disposed inside the second fixed plug, a piston block is disposed inside the detection bottle, and a light guiding layer is disposed at the inner middle end of the piston block.

[0014] Furthermore, the electrically controlled push rod drives the butt joint pipe to move upward to push open the water-isolating valve layer and pass through the drainage groove, and the butt joint pipe is connected with the interior of the detection bottle after passing through the drainage groove.

[0015] Furthermore, the outer contour of the piston block fits with the inner wall of the detection bottle, and the inner contour of the piston block fits with the outer wall of the transparent test tube.

[0016] The present invention provides a device for measuring the cloud point of an organosilicon surfactant, which has the following beneficial effects: 1. The present invention can heat the solution inside the detection bottle by working through the heating layer, and can rotate the magnetic rotor by working through the magnetic stirrer. The magnetic rotor can mix the solution during the rotation process to ensure that the organic silicon surfactant and the deionized water are evenly mixed. When the temperature rises to the cloud point of the organic silicon surfactant, the solution will become turbid and discolored. Since the clean water loaded inside the transparent test tube does not contact the solution in the detection bottle, the clean water can always remain clear. The inner and outer contours of the piston block are respectively fitted with the transparent test tube and the detection bottle, and a light guide layer is arranged at the middle end of the piston block, so that the light guide layer can guide the color of the clean water in the transparent test tube to the surface of the detection bottle. Through the above design, when the solution in the detection bottle reaches the cloud point and changes color, the inspection personnel or visual inspection equipment can confirm that the organic silicon surfactant has reached the cloud point through the obvious color difference between the light guide layer end and the solution side, and the thermometer in the transparent test tube can intuitively record the current water temperature. Through this design, the cloud point measurement of the organic silicon surfactant can be made efficient and concise while ensuring high accuracy.

[0017] 2. The present invention works through an electrically controlled push rod, which can drive the drain seat to move upward, so that the docking tube can slide inside the through groove and enter into the drainage trough. When the docking tube enters the drainage trough and continues to move upward, the water-isolating valve layer can be pushed open to enter the detection bottle. This allows the solution tested inside the detection bottle to enter the drain seat through the guidance of the docking tube. Because the diameter of the water inlet pipe is designed to be larger than the diameter of the docking tube, the water inlet speed is faster than the drainage speed. During the drainage process, the tester can fill the space inside the detection bottle up to the bottom of the piston block with clean water by injecting clean water into the water inlet pipe. This allows the clean water to clean the higher solution splashed during the stirring process. Through this design, the residue of silicone surfactant in the detection bottle can be effectively avoided, thereby affecting subsequent detection. The sewage that enters the drain seat can be discharged from the drain port through the drain hose. Through the above operation, the equipment can be quickly cleaned, thereby facilitating the subsequent group of silicone surfactant turbidity point detection, which makes the equipment detection process efficient.

[0018] 3. The air inlet pipe and the exhaust pipe of the present invention can be connected to the air delivery pump and the air extraction pump respectively. When the equipment is draining water, the air delivery pump can work to inject high-pressure gas into the detection bottle through the air inlet pipe. Under the high-pressure push of the high-pressure gas, the piston block can be driven to move inside the detection bottle. After the piston block contacts the water surface during the displacement process, the flow rate of the water flow can be increased, which increases the drainage speed of the equipment after the cleaning in the detection bottle is completed, thereby further improving the working efficiency of the equipment. During the displacement process, the piston block can scrape off the water adhering to the inner wall of the detection bottle. Through this design, the residue of organic silicon surfactant in the equipment can also be effectively avoided. In addition, with the assistance of the piston block, Pushing can effectively avoid water residue at the bottom of the test bottle, which can effectively avoid the problem of water not being able to be completely drained from the test bottle. After the drainage is completed, the vacuum pump can be used to extract the gas inside the test bottle through the exhaust pipe. When the gas in the test bottle is extracted, the piston block will move up and reset inside the test bottle due to the decrease in air pressure. During the upward and resetting process, the piston block can clean the inner wall of the test bottle again. Through this design, the position height of the piston block can be flexibly changed. 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 tester can quickly determine whether the ratio of the solution is correct after pouring the solution to be tested, which can effectively reduce the detection error rate of the equipment.

The bottom surface of the detection bottle 301 is in contact with the top surface of the magnetic stirrer 203, and the magnetic stirrer 203 drives the magnetic rotor 4 to rotate. The position and size of the through groove 204 correspond to the position and size of the docking pipe 104. The air inlet pipe 302, the exhaust pipe 303, and the water inlet pipe 306 are connected to the inside of the detection bottle 301, and the detection bottle 301 and the docking head 307 are integrated. The first fixing plug 5 is arranged inside the docking head 307, and the transparent test tube 6 is arranged inside the first fixing plug 5. The top inner side of the transparent test tube 6 is arranged A second fixed plug 7 is provided, and a thermometer 8 is arranged inside the second fixed plug 7. A piston block 9 is provided inside the detection bottle 301, and a light guide layer 10 is provided at the middle end of the piston block 9. The electric push rod 102 drives the butt joint pipe 104 to move upward to push open the water-isolating valve layer 305 and pass through the drainage groove 304. The butt joint pipe 104 is connected with the inside of the detection bottle 301 after passing through the drainage groove 304. The outer contour of the piston block 9 fits with the inner wall of the detection bottle 301, and the inner contour of the piston block 9 fits with the outer wall of the transparent test tube 6. The specific operation is as follows. The tester places the magnetic rotor 4 into the test bottle 301, and the magnetic rotor 4 can enter to the top of the test bottle 301. Then the staff engages the first fixing plug 5 with the docking joint 307, and then inserts the transparent test tube 6 into the first fixing plug 5, so that the transparent test tube 6 can be fixed through the first fixing plug 5 and the docking joint 307. The tester adjusts the height of the transparent test tube 6 inside the test bottle 301 to ensure that the transparent test tube 6 can be immersed in the solution of subsequent testing. The test bottle 301 is made of transparent quartz material, which makes it more intuitive to adjust the height of the transparent test tube 6 in the test bottle 301. After the transparent test tube 6 is adjusted, the tester injects clean water into the transparent test tube 6 and places the thermometer 8 into the transparent test tube 6. The thermometer 8 is fixed to the transparent test tube 6 by a second fixing plug 7, which can ensure the fixing stability between the thermometer 8 and the transparent test tube 6. After the thermometer 8 is fixedly 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 organic silicon surfactant to be tested with deionized water in 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 from the drainage groove 304. At this point, the preparation work before the test is completed. When the device is testing, the heating layer 202 works to heat the solution inside the test bottle 301, and the magnetic stirrer 203 works to rotate the magnetic rotor 4. The magnetic rotor 4 can mix the solution during the rotation to ensure that the organic silicon surfactant and the deionized water are evenly mixed. When the temperature rises to the cloud point of the organic silicon surfactant, the solution will become turbid and discolored. Since the clean water loaded in the transparent test tube 6 does not contact the solution in the test bottle 301, the clean water can always remain clear. The inner and outer contours of the piston block 9 are respectively fitted with the transparent test tube 6 and the test bottle 301, and the light guide layer 10 is arranged at the middle end of the piston block 9, so that the light guide layer 10 can guide the color of the clean water in the transparent test tube 6 Out to the surface of the detection bottle 301. Through the above design, when the solution in the detection bottle 301 reaches the turbidity point and changes color, the detection personnel or visual detection equipment can confirm that the organic silicon surfactant has reached the turbidity point through the obvious color difference between the end of the light guide layer 10 and the solution side, and the thermometer 8 in the transparent test tube 6 can intuitively record the current water temperature. Through this design, the turbidity point measurement of the organic silicon surfactant can be made efficient and simple while ensuring high accuracy. After the turbidity point detection of the organic silicon surfactant is completed, the electric control push rod 102 works to drive the sewage seat 103 to move up, which allows the butt joint pipe 104 to slide inside the through groove 204 and enter into the drainage groove 304. During the process of the butt joint pipe 104 entering the drainage groove 304 and continuing to move up,The water-isolating valve layer 305 can be pushed open to enter the interior of the test bottle 301, so that the solution tested in the test bottle 301 can be guided by the docking pipe 104 to enter the drain seat 103. Because the diameter of the water inlet pipe 306 is designed to be larger than the diameter of the docking pipe 104, the water inlet speed is faster than the water discharge speed. During the drainage process, the tester can fill the space inside the test bottle 301 up to the bottom of the piston block 9 with clean water by injecting clean water into the water inlet pipe 306. This allows the clean water to clean the higher solution splashed during the stirring process. Through this design, the silicone surfactant can be effectively avoided in The residue in the detection bottle 301 will affect the subsequent detection, and the sewage entering the drain seat 103 can be discharged from the drain port 106 through the drain hose 105. Through the above operation, the equipment can be quickly cleaned, so as to facilitate the subsequent group of organic silicon surfactant turbidity point detection, which makes the detection process of the equipment efficient. The air inlet pipe 302 and the exhaust pipe 303 can be connected to the air pump and the air pump respectively. During the drainage process of the equipment, the air pump can work to inject high-pressure gas into the detection bottle 301 through the air inlet pipe 302. Under the high pressure of the high-pressure gas, the piston block 9 can be driven The piston block 9 is displaced inside the detection bottle 301, and after contacting the water surface during the displacement process, the flow rate of the water flow can be increased, which increases the drainage speed of the device after the cleaning in the detection bottle 301 is completed, thereby further improving the working efficiency of the device. During the displacement process, the piston block 9 can scrape off the water adhering to the inner wall of the detection bottle 301. Through this design, the residue of organic silicon surfactant in the device can also be effectively avoided. In addition, the auxiliary downward push of the piston block 9 can effectively avoid the residue of water at the bottom of the detection bottle 301, which can effectively avoid the problem that the water in the detection bottle 301 cannot be completely drained, and the drainage After the water is finished, the air pump can be operated 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 will move up and reset inside the test bottle 301 due to the decrease in air pressure. During the upward reset process, the piston block 9 can clean the inner wall of the test bottle 301 again. Through this design, the position height of the piston block 9 can be flexibly changed. By adjusting the piston block 9 to the height where the volume of the test bottle 301 is the same as the volume of the solution to be tested, the tester can quickly determine whether the ratio of the solution is correct after pouring the solution to be tested, which can effectively reduce the detection error rate of the equipment.

[0023] In summary, when using the organic silicon surfactant turbidity point measuring device, the tester first places the magnetic rotor 4 into the detection bottle 301, and the magnetic rotor 4 can enter the top of the detection bottle 301. Then the staff engages the first fixing plug 5 with the docking head 307, and then inserts the transparent test tube 6 into the first fixing plug 5, so that the transparent test tube 6 can be fixed by the first fixing plug 5 and the docking head 307. The tester adjusts the height of the transparent test tube 6 inside the detection bottle 301 to ensure that the transparent test tube 6 can be immersed in the solution of the subsequent test. The detection bottle 301 is made of transparent quartz material, which makes it more intuitive to adjust the height of the transparent test tube 6 in the detection bottle 301. Then, after the transparent test tube 6 is raised, the tester injects clean water into the transparent test tube 6 and places the thermometer 8 into the transparent test tube 6. The thermometer 8 and the transparent test tube 6 are fixed by the second fixing plug 7, which can ensure the fixing stability between the thermometer 8 and the transparent test tube 6. After the thermometer 8 is fixed and inserted, 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 organic silicon surfactant to be tested with deionized water in 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 from the drainage groove 304. At this point, the preparation work before the test is completed; Then, the heating layer 202 is operated to heat the solution in the detection bottle 301, and the magnetic stirrer 203 is operated to rotate the magnetic rotor 4. The magnetic rotor 4 can mix the solution during the rotation process to ensure that the organic silicon surfactant and the deionized water are evenly mixed. When the temperature rises to the cloud point of the organic silicon surfactant, the solution will become turbid and discolored. Since the clean water in the transparent test tube 6 does not contact the solution in the detection bottle 301, the clean water can always remain clear. The inner and outer contours of the piston block 9 are respectively aligned with the transparent test tube 6 and the outer contours of the piston block 9. The detection bottle 301 is fitted, and a light-guiding layer 10 is arranged at the middle end of the piston block 9, so that the light-guiding layer 10 can guide the color of the clear water in the transparent test tube 6 to the surface of the detection bottle 301. Through the above design, when the solution in the detection bottle 301 reaches the turbidity point and changes color, the inspection personnel or visual inspection equipment can confirm that the organic silicon surfactant has reached the turbidity point through the obvious color difference between the end of the light-guiding layer 10 and the solution side, and the thermometer 8 in the transparent test tube 6 can intuitively record the current water temperature. Through this design, the turbidity point measurement of the organic silicon surfactant can be made efficient and simple while ensuring high accuracy; After the turbidity point test of the organic silicon surfactant is completed, the electric control push rod 102 can drive the drain seat 103 to move upward, so that the docking tube 104 can slide inside the through groove 204 and enter the drainage groove 304. When the docking tube 104 enters the drainage groove 304 and continues to move upward, the water-isolating valve layer 305 can be pushed open to enter the detection bottle 301. This allows the solution in the detection bottle 301 that has been tested to enter the drain seat 103 through the guidance of the docking tube 104. Because the diameter of the water inlet pipe 306 is larger than that of the docking tube 104, the water inlet speed is faster than the drainage speed. During the drainage process, the tester can fill the space inside the test bottle 301 up to the bottom of the piston block 9 with clean water by injecting clean water into the water inlet pipe 306, so that the clean water can clean the higher solution splashed during the stirring process. Through this design, it can effectively avoid the residue of organic silicon surfactant in the test bottle 301, thereby affecting the subsequent detection; and the sewage entering the sewage seat 103 can be discharged from the sewage outlet 106 through the sewage hose 105. Through the above operation, the equipment can be quickly cleaned, so as to facilitate the subsequent group of organic silicon surfactant turbidity point detection, which makes the detection process of the equipment efficient; Finally, during the drainage process, the device can inject high-pressure gas into the detection bottle 301 through the air inlet pipe 302 through the air pump. Under the high pressure of the high-pressure gas, the piston block 9 can be driven to move inside the detection bottle 301. After the piston block 9 contacts the water surface during the displacement process, the flow rate of the water flow can be increased, which increases the drainage speed of the device after the cleaning in the detection bottle 301 is completed, thereby further improving the working efficiency of the device. During the displacement process, the piston block 9 can scrape off the water adhering to the inner wall of the detection bottle 301. Through this design, the residue of organic silicon surfactant in the device can also be effectively avoided. In addition, the auxiliary downward push of the piston block 9 can effectively avoid the water in the detection bottle 301. The residue at the bottom can effectively avoid the problem that the water in the test bottle 301 cannot be completely drained. After the drainage is completed, the air pump can be used to extract the gas inside the test bottle 301 through the exhaust pipe 303. When the gas in the test bottle 301 is extracted, the piston block 9 will move up and reset inside the test bottle 301 due to the decrease in air pressure. During the upward and resetting process, the piston block 9 can clean the inner wall of the test bottle 301 again. Through this design, the position height of the piston block 9 can be flexibly changed. By adjusting the piston block 9 to the height where the volume of the test bottle 301 is the same as the volume of the solution to be tested, the tester can quickly determine whether the ratio of the solution is correct after pouring the solution to be tested, which can effectively reduce the detection error rate of the equipment.
