Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of silicone oil synthesis, especially to silicone oil synthesis device. BACKGROUND

[0002] Silicone oil is a linear polysiloxane product that remains liquid at room temperature. It is an organosilicon compound with a silicon-oxygen bond (Si-O) backbone and organic groups directly attached to the silicon atoms. Silicone oil synthesis device is a professional equipment system for producing silicone oil. It mainly synthesizes silicone oil products with different properties and uses by a series of chemical reactions and physical treatment processes under specific reaction conditions using siloxane monomers and other raw materials.

[0003] During the synthesis of silicone oil, ring-opening polymerization or condensation polymerization occurs in the presence of a catalyst in a reaction kettle. For example, in the case of octamethylcyclotetrasiloxane (D4) ring-opening polymerization, the silicon-oxygen bond of D4 breaks under the conditions of heating, stirring, and the presence of a catalyst, and ring-opening polymerization occurs, gradually forming polydimethylsiloxane chains with different degrees of polymerization. As the polymerization reaction progresses, the material in the stirring kettle is gradually taken out by the stirring paddle to form a silicone oil preliminary product with a certain molecular weight and viscosity.

[0004] In the prior art, most silicone oil synthesis devices cannot mix the reactants uniformly at the initial stage of the reaction because the stirring paddle cannot generate sufficient shear force and mixing flow, which affects the reaction rate and the quality of the initial polymerization of silicone oil. As the reaction progresses into the later stage, the product gradually forms. If high-intensity stirring is continued at this time, the fixed-angle stirring paddle can easily cause excessive shearing of the formed silicone oil molecular chain, leading to problems such as a wide molecular weight distribution of silicone oil, unstable performance, and reduced quality and consistency of the silicone oil product. Therefore, the stirring paddle cannot be adjusted according to the needs of different reaction periods, and the device adaptability is reduced. SUMMARY

[0005] To address the above problems, the utility model provides a silicone oil synthesis device to improve the adaptability of the device.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0018] As a further description of the above technical solution:

[0019] The opposite sides of the plurality of rotating plates are in contact with the adjacent sides of the plurality of circular plates, and the opposite sides of the plurality of circular plates are in contact with the left and right sides of the inner wall of the rotating shaft.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a silicone oil synthesis apparatus, including a reactor 1, a container for silicone oil synthesis reactions. A fixing frame 2 is fixedly connected to the outer wall of the reactor 1. The fixing frame 2 stabilizes the reactor 1 and is connected to the reactor 1 by welding or other reliable connection methods, ensuring that the reactor 1 will not shake or shift during operation, thus guaranteeing the stability of the entire apparatus. A feed pipe 3 is fixedly connected to the top left end of the reactor 1.

A protective column 4 is fixedly connected to the top side of the reactor 1 to protect the internal components.

[0034] A drive assembly for rotating subsequent components is fixedly connected inside the protective column 4. The drive assembly includes a motor 26, which is externally fixedly connected inside the protective column 4. The motor 26 is connected to the protective column 4 via welding, ensuring a stable drive source. A rotating shaft 5 is fixedly connected to the drive end of the motor 26, transmitting the rotational force to subsequent components. The rotating shaft 5 is externally rotatably connected to the inner wall of the bottom end of the protective column 4, allowing it to rotate stably through the restraint and guidance of the protective column 4. A connecting frame 6 is fixedly connected to the external side of the rotating shaft 5, transmitting the rotational force to the connecting frame 6. Scrapers 7 are fixedly connected to opposite sides of the connecting frame 6, causing the scrapers 7 to rotate around the rotating shaft 5 when subjected to force. The opposite sides of the two scrapers 7 are slidably connected to the inner wall of the reactor 1, cleaning the interior of the reactor 1 through the rotation of the connecting frame 6.

[0035] ReferenceFigures 2 to 4 A cylinder 8 is fixedly connected to the top inner wall of the drive assembly, and a rotating shaft 5 is fixedly connected to the top of the cylinder 8 via a welding process, allowing the cylinder 8 to stably provide a drive source. A push plate 9 is fixedly connected to the drive end of the cylinder 8, transmitting the force from the drive end of the cylinder 8 to subsequent components. Multiple fixed posts 10 are fixedly connected to opposite sides of the push plate 9, transmitting sliding force to the fixed posts 10, allowing them to slide up and down. A rotating plate 11 is rotatably connected to the outside of the fixed posts 10, allowing the rotating plate 11 to rotate around the fixed post 10 after being subjected to force. A connecting post 12 is rotatably connected to the end of the rotating plate 11 away from the fixed post 10, transmitting force to the connecting post 12. A circular plate 13 is fixedly connected to the opposite side of the multiple connecting posts 12, causing the circular plate 13 to rotate after being subjected to force.

[0036] The opposite sides of multiple rotating plates 11 contact the adjacent sides of multiple circular plates 13, ensuring tight contact between the rotating plates 11 and the circular plates 13 and preventing them from shifting or falling off. The opposite sides of the multiple circular plates 13 contact the left and right sides of the inner wall of the rotating shaft 5, ensuring stable rotation through tight contact between the rotating shaft 5 and the circular plates 13. Rotating columns 14 are fixedly connected to the opposite sides of each of the multiple circular plates 13, and are connected to the circular plates 13 and rotating columns 14 through welding, allowing the rotating columns 14 to transmit the rotational force of the circular plates 13 to subsequent components. The outer sides of the multiple rotating columns 14 are rotatably connected to the inner walls of the left and right ends of the rotating shaft 5, ensuring stable rotation through the constraint of the rotating shaft 5.

[0037] A limiting ring 15 is fixedly connected to the outside of the rotating column 14 to prevent it from shifting. Multiple limiting rings 15 are rotatably connected to the inner walls of the left and right ends of the rotating shaft 5, ensuring stable rotation. Stirring paddles 16 are fixedly connected to the far sides of the multiple rotating columns 14 to agitate the raw materials and accelerate the reaction rate. Two rubber plates 17 are fixedly connected to the bottom of the drive assembly, and the bottom of the rotating shaft 5 is fixedly connected to the near side of the two rubber plates 17, causing the two rubber plates 17 to rotate when the shaft 5 rotates. Two force-bearing plates 18 are fixedly connected to the inner wall of the reactor 1 away from the protective column 4, and are connected to the reactor 1 and the force-bearing plates 18 by welding. The outer surfaces of the rubber plates 17 are in contact with the outer surfaces of the force-bearing plates 18, and the rotation of the rubber plates 17 impacts the force-bearing plates 18.

[0038] Reference Figure 1 , Figure 2 and Figure 5A discharge pipe 19 is fixedly connected to the end of the reactor 1 furthest from the protective column 4 to allow the initially generated silicone oil to flow out. A valve 20 is installed on the outside of the discharge pipe 19 to control the flow rate of the silicone oil. A fixing ring 21 is fixedly connected to the bottom end of the discharge pipe 19, and the discharge pipe 19 and the fixing ring 21 are connected by welding, so that the fixing ring 21 can provide support for subsequent components. Multiple connecting plates 22 are fixedly connected to the outer wall of the fixing ring 21, and the fixing ring 21 is connected to the connecting plates 22 by welding, so that the fixing ring 21 can provide support for subsequent components. A support ring 23 is fixedly connected to the bottom end of the multiple connecting plates 22 on the adjacent side to guide the silicone oil out. A triangular filter column 24 is fixedly connected to the side of the support ring 23 near the protective column 4 to filter the silicone oil produced by the reaction, thereby improving the quality of the silicone oil. A right-angle tube 25 is fixedly connected to the end of the support ring 23 furthest from the protective column 4 to lead out the silicone oil for subsequent operations.

[0039] Working principle: Siloxane monomers, catalysts, solvents, etc., are prepared in proportion and transported to the reaction vessel 1 through the feed pipe 3. Then, the drive motor 26 drives the rotating shaft 5 to rotate, thereby driving the rotating column 14 to rotate, which in turn drives the stirring paddle 16 to rotate to provide the reaction rate. At the same time, according to the needs of different stages, the drive cylinder 8 drives the push plate 9 to slide up and down, which in turn drives the fixed column 10 to slide, thereby driving the rotating plate 11 to rotate around the fixed column 10 and drive the connecting column 12 to rotate. The connecting column 12 drives the circular plate 13 to rotate, which in turn drives the rotating column 14 to rotate, thereby driving the stirring paddle 16 to rotate. The angle of the stirring paddle 16 can be adjusted to adapt to different stages of the reaction, avoid uneven mixing and unstable performance, and thus improve the adaptability of the device.

[0040] After the reaction is complete, valve 20 on the discharge pipe 19 is opened, and the silicone oil flows out through the discharge pipe 19 under gravity. During the outflow process, the silicone oil first passes through the triangular filter column 24 for filtration to remove impurity particles and improve the quality of the silicone oil. Then, it flows out of the reactor 1 through the right-angle pipe 25 and enters the subsequent storage or further processing stage. During the rotation of the rotating shaft 5, the rubber plate 17 will also rotate, thereby striking the force plate 18. The force plate 18 transmits the vibration force to the reactor 1, then to the fixed ring 21, and then to the support ring 23 through the connecting plate 22. This allows the triangular filter column 24, which is fixed to the support ring 23, to vibrate, so that impurities in the silicone oil product will not get stuck, thereby improving the filtration effect.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
