Description

Technical Field

[0001] The present invention relates to a continuous production process and device for the conversion of organosilicon monomers, belonging to the technical field of organosilicon monomer production. Background Art

[0002] Organosilicon is an important class of organic-inorganic composite materials, mainly composed of silicon atoms (Si) chemically bonded to organic groups. The conversion of organosilicon monomers is an important link in the industrial production of organosilicon, which refers to changing the structure or functional groups of organosilicon monomers through chemical reactions to synthesize organosilicon compounds with specific properties.

[0003] However, the existing process for the conversion of organosilicon monomers has poor continuity, which leads to frequent interruptions in the production process, resulting in low equipment utilization rate, extended production cycle, difficulty in meeting the large market demand for organosilicon monomers, and further affecting the stability of product quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is that the existing process for the conversion of organosilicon monomers has poor continuity, which leads to frequent interruptions in the production process, resulting in low equipment utilization rate, extended production cycle, difficulty in meeting the large market demand for organosilicon monomers, and further affecting the stability of product quality.

[0005] To solve the above problems, the present invention provides a continuous production device for the conversion of organosilicon monomers, including a reaction kettle, a mixing mechanism, a partition layer, and a discharging mechanism. The upper and lower ends of the reaction kettle are respectively connected with a feed pipe and a discharge pipe. The mixing mechanism is arranged at the central position inside the reaction kettle. The mixing mechanism includes stirring blades. Two partition layers are arranged inside the reaction kettle and correspond to the positions of the stirring blades. Two discharging mechanisms are respectively arranged at the upper and lower ends of the reaction kettle. The partition layer is provided with slot holes, and one end of the discharging mechanism is provided with a sealing plate corresponding to the slot holes.

[0006] Further: The mixing mechanism further includes a motor and a stirring shaft. The motor is arranged at the upper end of the reaction kettle. The output shaft of the motor penetrates through the reaction kettle and is fixedly connected with the stirring shaft. A plurality of stirring blades are evenly distributed on the side surface of the stirring rod.

[0007] Further: The stirring shaft penetrates through the partition layer, and the gap between the stirring shaft and the partition layer is sealed by a sealing block to prevent liquid from flowing out through the gap between the two.

[0008] Further: An arc-shaped plate is arranged at the lower end of the stirring blade above the partition layer.

[0009] Further: The discharging mechanism further includes air cylinders, telescopic shafts, and connecting columns. The two air cylinders are respectively arranged at both ends of the reaction kettle. The output end of the air cylinder is fixedly connected to the telescopic shaft. The connecting column is fixedly connected to the end of the telescopic shaft, and the connecting column is fixedly connected to the sealing plate.

[0010] Further: The upper end of the reaction kettle is communicated with a catalyst injection pipe.

[0011] Further: The lower end of the discharge pipe is rotatably connected with an electric cover plate.

[0012] Further: The lower end of the reaction kettle is provided with uniformly distributed legs.

[0013] The present invention also provides a production process of a silicon micropowder modification device.

[0014] Equipment connection and by-product introduction: When performing monomer conversion, the feed pipe of the reaction kettle and the exhaust pipe of the by-product are connected through an external connection pipeline, and by-products such as high-boiling substances and low-boiling substances are introduced onto the separation layer of the reaction kettle.

[0015] Reaction start: The motor drives the stirring blades on the stirring shaft to rotate, making the reaction faster and more complete.

[0016] Catalytic reaction progress: Under the action of the catalyst, the by-products react with reactants such as hydrogen chloride to generate the target monomer.

[0017] New by-product treatment preparation: When there are new by-products during the reaction process that need to react, the air cylinder can be driven to extend and retract its telescopic shaft. The sealing plate at the end of the connecting column is moved out from the separation layer, and the reaction liquid flows into the lower separation layer for reaction.

[0018] Sealing and continuous reaction: Then the sealing plate is reset to seal the separation layer. The reactants can be continuously injected through the feed pipe above the reaction kettle for reaction.

[0019] Reaction end and discharge: After the reaction ends, the reaction liquid is discharged from the liquid outlet pipe.

[0020] Further: During the reaction process, the catalyst required for the reaction is injected through the catalyst injection pipe.

[0021] The advantages of the present invention compared with the prior art are as follows:

[0022] In this patent, by setting the discharging mechanism in cooperation with the partition plate, the reactants on multiple partition plates can react simultaneously. When new reactants are injected, the reactants on the upper partition plate can be transported to the lower layer for continuous reaction, thus avoiding the problems of frequent interruption in the production process, low equipment utilization rate, and extended production cycle.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Combined with the attached Figure 1 、 2, 4. The present invention provides a continuous production device for the conversion of organosilicon monomers, which includes a reaction kettle 1, a mixing mechanism 2, a partition layer 3, and a discharging mechanism 4. The upper and lower ends of the reaction kettle 1 are respectively connected with a feed pipe and a discharge pipe. The lower end of the reaction kettle 1 is provided with uniformly distributed legs. The lower end of the discharge pipe is rotatably connected with an electric cover plate. The mixing mechanism 2 is arranged at the central position inside the reaction kettle 1. The mixing mechanism 2 includes stirring blades 21. Two partition layers 3 are arranged inside the reaction kettle 1 and correspond to the position of the stirring blades 21. An arc-shaped plate 24 is provided at the lower end of the stirring blade 21 above the partition layer 3 to prevent the reactants from settling on the partition layer 3. The mixing mechanism 2 further includes a motor 22 and a stirring shaft 23. The motor 22 is arranged at the upper end of the reaction kettle 1. The output shaft of the motor 22 penetrates the reaction kettle 1 and is fixedly connected with the stirring shaft 23. The stirring shaft 23 penetrates the partition layer 3, and the gap between the stirring shaft 23 and the partition layer 3 is sealed by a sealing block to prevent the liquid from flowing out through the gap between the two. A plurality of stirring blades 21 are uniformly distributed on the side of the stirring rod. The upper end of the reaction kettle 1 is connected with a catalyst injection pipe 11. When carrying out the monomer conversion, the feed pipe of the reaction kettle 1 is connected with the exhaust pipe of the by-products through an external connecting pipe. By-products such as high-boiling substances and low-boiling substances enter the partition layer 3 of the reaction kettle 1. The motor 22 drives the arc-shaped plate 24 on the stirring shaft 23 to rotate, making the reaction faster and more complete. Under the action of the catalyst, the by-products react with reactants such as hydrogen chloride to generate the target monomer;

[0032] Combined with the attached Figures 1-4 , two discharging mechanisms 4 are respectively arranged at the upper and lower ends of the reaction kettle 1. The partition layer 3 is provided with slot holes 31. One end of the discharging mechanism 4 is provided with a sealing plate 41 corresponding to the slot holes 31. The discharging mechanism 4 further includes a cylinder 42, a telescopic shaft 43, and a connecting column 44. Two cylinders 42 are respectively arranged at both ends of the reaction kettle 1. The output end of the cylinder 42 is fixedly connected with the telescopic shaft 43. The connecting column 44 is fixedly connected to the end of the telescopic shaft 43. The connecting column 44 is fixedly connected with the sealing plate 41. When there are new by-products during the reaction process that need to react, the cylinder 42 can be driven to make its telescopic shaft 43 extend and retract, so that the sealing plate 41 at the end of the connecting column 44 is moved out from the partition layer 3, enabling the reaction liquid to flow into the lower partition layer 3 for reaction, and then the sealing plate 41 is reset to seal the partition layer 3. Then, the reactants can be continuously injected through the feed pipe above the reaction kettle 1 for reaction without interrupting the production process, effectively ensuring the production efficiency and equipment utilization rate. After the reaction is completed, the reaction liquid can be discharged from the liquid discharge pipe.

[0033] The working principle of this application is as follows:

[0034] When performing monomer conversion, the feed pipe of the reaction kettle 1 and the exhaust pipe of by-products are connected through an external connecting pipe. By-products such as high-boiling substances and low-boiling substances enter the separation layer 3 of the reaction kettle 1. The motor 22 drives the arc-shaped plate 24 on the stirring shaft 23 to rotate, making the reaction faster and more complete. Under the action of the catalyst, the by-products react with reactants such as hydrogen chloride to generate the target monomer. When there are new by-products during the reaction process that need to react, the cylinder 42 can drive its telescopic shaft 43 to stretch and retract, so that the sealing plate 41 at the end of the connecting column 44 is removed from the separation layer 3, allowing the reaction liquid to flow into the lower separation layer 3 for reaction. Then, the sealing plate 41 is reset to seal the separation layer 3, and reactants can be continuously injected through the feed pipe above the reaction kettle 1 for reaction without interrupting the production process, effectively ensuring the production efficiency and equipment utilization rate. After the reaction is completed, the reaction liquid can be discharged from the liquid outlet pipe.

[0035] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they should all fall within the protection scope of the present invention.
