Description

Technical Field

[0001] The present invention relates to the technical field of active agent monitoring, in particular to a monitoring device for the production process of an organosilicon surfactant. Background Art

[0002] With the rise of new organosilicon materials, organosilicon surfactants have become a research hotspot in recent years. Because their structure contains both organic groups and silicon-oxygen bonds (Si-O-Si), organosilicon surfactants not only possess the high surface activity of general hydrocarbon surfactants, but also possess the excellent properties of inorganic silica, such as high and low temperature resistance, weathering resistance, non-toxicity, non-corrosiveness, and physiological inertness. They are suitable for use in textiles, pesticides, daily chemical products, and more.

[0003] During the production of organosilicon surfactants, hydrogen content directly impacts their performance. Effectively controlling and accurately measuring hydrogen content during the production process is of significant theoretical and practical significance for efficient product preparation. Current methods for determining hydrogen content include infrared, chemical, and gas flow methods. Chemical methods are more mature, but they are cumbersome and inefficient. Gas flow methods require simple equipment, but hydrogen's volume fluctuates significantly with temperature, and manual manipulation can significantly influence the test results, leading to significant errors.

During the regulation, the integration of hydrogen can be accelerated and the material can be prevented from adhering to the inner wall of the device.

[0017] 1. Before use, the present invention first draws a standard curve (linear relationship) in the laboratory. After the linear relationship is established, the material can be put into the tank from the feed port for stirring and processing. During the production process, the control valve is opened regularly, and the sampling pump can draw the reaction product in the tank through the sampling tube into the FTIR detection device for detection, thereby utilizing the established linear relationship to determine the hydrogen content of the sample in the production process.

[0018] When the air in the tank is exhausted, the exhaust gas will be sucked out of the tank, and the exhaust gas in the tank will be sucked out of the tank, so that the exhaust gas in the tank can be sucked out of the tank, and the exhaust gas in the tank can be sucked out of the tank, so that the exhaust gas in the tank can be sucked out of the tank, and the exhaust gas in the tank can be sucked out of the tank, so that the exhaust gas in the tank can be sucked out of the tank, and the exhaust gas in the tank can be sucked out of the tank, and the exhaust gas in the tank can be sucked out of the tank, so that the exhaust gas in the tank can be sucked out of the tank, and the exhaust gas in the tank can be sucked out of the tank,

[0019] 3. In the present invention, after the material enters the tank body, the driving motor is started, and the driving wheel can be driven to rotate by the driving wheel, thereby driving the stirring rod to rotate in the tank body through the stirring shaft to mix and stir the material. The one-way valve at the end of the stirring rod can prevent the material from entering the stirring rod, and when the stirring shaft rotates, it can drive the center wheel to rotate synchronously, and drive the ring plate to rotate through the planetary gear. The support plate and the tank body can limit the ring plate through the ring groove and the rotating ring to prevent the ring plate from deflecting during rotation. The support plate can shield the gap between the ring plate, the planetary gear and the center wheel through the ring groove and the rotating ring to prevent the material from splashing into the ring plate, the planetary gear and the center wheel during stirring. The ring plate can drive the scraper to move synchronously in the tank body when it rotates, and the movement direction of the scraper is opposite to that of the stirring rod, thereby improving the mixing efficiency of the material and cleaning the inner wall of the tank body to avoid the material from adhering to the inner wall of the tank body and being difficult to clean. When the air supply pipe supplies air to the tank body, the gas enters the ventilation cavity from the air supply pipe and can enter the tank body through the stirring rod. As the stirring rod moves, it is directly mixed with the material to accelerate the integration and reaction of the gas. In summary, when in use, the mixing efficiency of the material can be improved, the integration and reaction of hydrogen can be accelerated, and the material can be prevented from adhering to the inner wall of the device.
