Description

Technical Field

[0001] This utility model relates to the chemical field, particularly to chemical equipment, and especially to a reaction vessel for producing organosilicon, specifically a reaction vessel for producing organosilicon surfactants with a dispersing effect. Background Technology

[0002] Organosilicon surfactants are surfactants containing organosilicon bonds. Due to the presence of hydrophilic and hydrophobic groups in their molecules, they exhibit excellent dispersing, wetting, and emulsifying properties, and are widely used in industry, agriculture, daily chemicals, and medicine. The direct synthesis method of organosilicon surfactants is a process that prepares them by directly reacting silane monomers or polysiloxanes with active components. For example, silicone oil (such as linear polysiloxanes) can be used as a raw material, reacting directly with active hydrogen compounds to generate surfactants. Specifically, monomers such as chloromethylsilane and chlorophenylsilane can undergo condensation polymerization with silicon trichloride at a certain temperature to form silicone oil, which then reacts with other active components.

[0003] Reactors used for producing organosilicon surfactants employ various types of agitators, with frame agitators being a common type. However, current reactors using frame agitators for organosilicon surfactant production struggle to disperse the raw materials during stirring, resulting in poor reaction outcomes. While some designs incorporate through-holes in plate-type impellers, which can disperse the raw materials, they suffer from poor structural stability. Therefore, an improved technology is urgently needed to address the aforementioned problems in existing technologies. Utility Model Content

The upper surface of the vessel cover 2 is also provided with a thermometer port 16, a pressure gauge port 17 and a manhole 18. The thermometer port 16 and the pressure gauge port 17 are used to install thermometers and pressure gauges respectively. The manhole 18 is used for personnel to enter the vessel body 1 for maintenance, repair, etc.

[0027] The frame-type stirring paddle includes a main shaft 6, U-shaped blades 7, and dispersing blades 8. The top end of the main shaft 6 is connected to the output shaft of the drive motor 5 via a coupling. The main shaft 6 is located inside the vessel body 1 and is connected to the U-shaped blades 7. Several dispersing blades 8 are symmetrically arranged between the two sides of the main shaft 6 and the U-shaped blades 7. Each dispersing blade 8 has a reinforcing rod 9 on both sides. One end of the reinforcing rod 9 is connected to the U-shaped blade 7. An arc-shaped groove is opened in the middle of the reinforcing rod 9. The arc-shaped groove of the reinforcing rod 9 cooperates with the main shaft 6 to achieve the connection between the middle part of the reinforcing rod 9 and the main shaft 6.

[0028] The U-shaped blade 7 has several first dispersing holes 10 through it along its thickness direction. The outer surface of the U-shaped blade 7 is adjacent to the inner wall of the vessel body 1. The residual organosilicon on the inner wall of the vessel body 1 can be scraped off through the U-shaped blade 7.

[0029] The dispersing blade 8 has two rows of intersecting second dispersing holes 11. The upper surface of the dispersing blade 8 has several upper dispersing grooves 12, and the lower surface of the dispersing blade 8 has several lower dispersing grooves 13. The upper dispersing grooves 12 correspond one-to-one with the positions of the second dispersing holes 11 in the next row, and the lower dispersing grooves 13 correspond one-to-one with the positions of the second dispersing holes 11 in the previous row.

[0030] Installation method and operating principle: First, process the U-shaped impeller 7 and the dispersing impeller 8. The U-shaped impeller 7 has several first dispersing holes 10 through it along its thickness direction. The dispersing impeller 8 has two rows of second dispersing holes 11. The upper surface of the dispersing impeller 8 has several upper dispersing grooves 12, and the lower surface of the dispersing impeller 8 has several lower dispersing grooves 13. Next, assemble the frame-type agitator. Weld the middle position of the U-shaped impeller 7 to the bottom end of the main shaft 6. Then, weld the multiple dispersing impellers 8 to both sides of the main shaft 6 in pairs. Weld the outer ends of the dispersing impellers 8 to the inner wall of the U-shaped impeller 7. Finally, weld the reinforcing rod 9 to both sides of the dispersing impeller 8. Weld the two ends of the reinforcing rod 9 to the side surfaces of the U-shaped impeller 7 to complete the assembly of the frame-type agitator. The drive motor 5 is installed on the upper surface of the motor base 4 on the vessel cover 2. The top end of the main shaft 6 is connected to the output shaft of the drive motor 5 via a coupling. After lifting the vessel cover 2, the U-shaped blade 7 is placed inside the vessel body 1. The cover is then fastened to the upper surface of the vessel body 1 with bolts to complete the installation. During operation, silane monomers or polysiloxanes are directly added to the vessel body 1 along with the active components through the raw material port 15. High-temperature hot gas is sent into the jacket 3 from the heat exchange medium inlet 20, where they are mixed and stirred at 80°C to condense and generate silicone oil. When the drive motor 5 drives the frame-type stirring paddle to rotate, the raw materials are dispersed and bubbles are generated through the first dispersing hole 10 of the U-shaped blade 7, the second dispersing hole 11 of the dispersing blade 8, and the upper and lower dispersing grooves 12 and 13. This allows the silane monomer or polysiloxane to fully contact the active component, greatly improving the reaction effect and thus increasing production efficiency. Furthermore, both sides of the dispersing blade 8 are equipped with reinforcing rods 9, with both ends of the reinforcing rods 9 extending to the U-shaped blade 7 and connecting to the side surface of the U-shaped blade 7. The reinforcement of the reinforcing rods 9 ensures the structural strength of the dispersing blade 8, thereby ensuring the structural strength and stability of the dispersing blade 8 (the second dispersing hole 11, upper dispersing groove 12, and lower dispersing groove 13 on the dispersing blade 8 lead to a decrease in strength and stability), thus ensuring the dispersing effect of the material.
