Description

Technical Field

[0001] This utility model relates to the field of chemical preparation equipment technology, and in particular to a hydrogen-containing silicone oil synthesis reactor with in-situ separation function. Background Technology

[0002] Hydrogen-containing silicone oils are typically synthesized via chlorosilane hydrolysis or hydrosilylation. Using chlorosilanes as raw materials, hydrolysis generates siloxane intermediates, which are then subjected to acid-base equilibrium adjustment and cracking condensation to obtain linear or cyclic hydrogen-containing siloxanes. Subsequently, under the action of a catalyst, the hydrogen-containing siloxanes are further polymerized through hydrosilylation reactions, controlling their molecular weight and hydrogen content to ultimately obtain the target product.

[0003] The synthesis of hydrogen-containing silicone oil involves key steps such as hydrolysis, condensation polymerization, and hydrosilylation. During hydrolysis, uniform stirring promotes sufficient contact between chlorosilanes and water, reducing the formation of byproducts caused by localized, vigorous reactions. During condensation polymerization and hydrosilylation reactions, stirring helps to achieve uniform catalyst distribution, improving reaction rate and selectivity. Existing equipment lacks in-situ separation capabilities, leading to the accumulation of byproducts, increased system viscosity, and compromised stirring uniformity, resulting in incomplete reactions. Utility Model Content

[0004] The technical problem to be solved by this invention is that existing devices are prone to the accumulation of by-products, which increases the viscosity of the system, affects the uniformity of the mixing reaction, and reduces the reaction efficiency.

It should also be understood that the term “and / or” as used herein refers to and includes one or more of the associated listed items, any or all possible combinations thereof.

[0020] To make the technical problems to be solved, the technical solutions, and the beneficial effects of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This utility model provides a hydrogen-containing silicone oil synthesis reactor with in-situ separation function, including a working mechanism and a reactor body 1;

[0022] As attached Figure 1 , 2 As shown, the working mechanism and the vessel body 1 are fastened together. The vessel body 1 is a traditional cylindrical container. The working mechanism includes a working plate 2 and a base frame 3. A drive motor is fixedly installed on the top of the working plate 2. An injection port is opened on one side of the drive motor. The output end of the drive motor passes through the working plate 2, and a filter plate 5 is fixedly installed at the bottom. The filter plate 5 is made of activated carbon impregnated with alkali solution, which filters and adsorbs impurities in the vessel and can also adsorb acidic gases in the vessel. A circular groove is opened on the center side of the filter plate 5 for the adsorption filter cartridge 6 to pass through.

[0023] As attached Figure 1-3 As shown, the base frame 3 is configured as an inverted bucket-shaped connecting base plate, with a filter screen plate fixed at the bottom. Multiple snap-fit ​​grooves 7 are provided on the center side of the base frame 3, which are securely snapped into the bottom end of the adsorption filter cartridge 6. This ensures a tight connection between the base frame 3 and the adsorption filter cartridge 6. Simultaneously, since the filter plate 5 has a circular groove on its center side for the adsorption filter cartridge 6 to pass through, space is created for the adsorption filter cartridge 6 to pass through when the filter plate 5 moves up and down. The diameter of the connecting base plate is smaller than the diameter of the reactor mouth, facilitating its placement inside the reactor. Multiple filter holes are provided around the connecting base plate. Assembly frames 4 are fixedly installed on both sides of the base frame 3, and the base frame 3 is slidably connected to the filter plate 5 through the assembly frames 4. Multiple adsorption filter cartridges 6 are securely snapped into the top of the base frame 3. The outer wall of the adsorption filter cartridge 6 has a filter screen groove, and the interior of the adsorption filter cartridge 6 is filled with non-polar macroporous resin for effective adsorption of unreacted hydrides and catalyst degradation products.

[0024] As attached Figure 1-4 As shown, a connecting arm 10 is fixedly installed on the top of the assembly frame 4. The connecting arm 10 is an L-shaped plate structure, and its top is fastened to the vessel body 1 by mounting bolts. The working mechanism and the vessel body 1 are fastened together by the connecting arm 10 and the mounting bolts. A vertical slot 8 is opened through the assembly frame 4, extending to the top of the assembly frame 4. Guide blocks are fixedly installed on both sides of the filter plate 5, which provide the filter plate 5 with the ability to move up and down during the vertical reciprocating motion through the guide blocks and the vertical slot 8. Threaded plates 9 are fixedly installed on both sides of the top of the assembly frame 4, and the threaded plates 9 are fastened to the bottom side of the working plate 2 by assembly bolts; this is used to ensure the tight assembly connection between the working plate 2 and the base frame 3.

[0025] Working Principle: In practical implementation, the working mechanism is first placed inside the reactor body 1. The connecting arm 10 and mounting bolts at the top of the working plate 2 are securely connected to the top of the reactor body 1. The injection pipe is connected to the injection port at the top of the working plate 2, continuously injecting the reaction liquid and catalyst into the reactor. The degradation products are effectively adsorbed through the filter screen of the base frame 3, the multiple filter holes around it, and the adsorption filter cartridge 6, which is filled with non-polar macroporous resin. Then, after the reactant has submerged the top of the adsorption filter cartridge 6, the drive motor is activated, causing its output end to drive the filter plate 5 in a reciprocating motion. Because the filter plate 5 is made of alkaline-impregnated activated carbon and undergoes reciprocating filtration within the reactor, it effectively adsorbs impurities and acidic gases within the reactor.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
