Abstract
Description
Technical Field
[0001] This utility model relates to the field of dimethyl silicone oil production and processing technology, and in particular to a dimethyl silicone oil mixing reactor with heat exchange function. Background Technology
[0002] Dimethyl silicone oil is colorless, transparent, odorless, and non-toxic. It is readily soluble in benzene, toluene, xylene, diethyl ether, and chlorinated alkanes. It possesses excellent chemical stability and lubrication properties, and is widely used in cosmetics, pharmaceuticals, food, rubber and plastics, textiles, electronics, electrical appliances, and machinery lubrication. It can be used as a mold release agent, lubricant, and defoamer. The production of dimethyl silicone oil mainly includes processes such as synthesis, cracking, refining, and blending.
[0003] First, linear siloxanes are obtained by hydrolysis and condensation of raw materials such as silicon powder and methylchlorosilane. Then, viscosity is controlled by cracking, followed by distillation to remove oligomers and impurities. Finally, viscosity and properties are adjusted as needed. Strict control of temperature, catalyst dosage, and purity is required during production to ensure stable product quality. However, in the dimethyl silicone oil production process, insufficient raw material purity or temperature deviations can easily limit reaction efficiency, disrupt reaction equilibrium, and affect product quality. Utility Model Content
[0004] The technical problem this invention aims to solve is that the heat exchange efficiency is limited in the production process of dimethyl silicone oil, which affects product quality.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a dimethyl silicone oil mixing reactor with heat exchange function, including a reactor body and a first sealing plate. A push rod motor is fixedly installed on the top of the first sealing plate. The output end of the push rod motor passes through the first sealing plate, and an electric heating chamber is fixedly connected to the bottom of the output end. A second sealing plate is fixedly installed at the bottom of the electric heating chamber. A thermocouple passing through the second sealing plate is built into the electric heating chamber, and multiple heat-conducting chambers are fixedly connected to the bottom side of the thermocouple. The heat-conducting chambers contain heating fluid.
[0006] As a further improvement of this utility model, a through groove is provided on one side of the first sealing plate and the second sealing plate, and a liquid injection pipe is installed inside the through groove. A sealing ring is fixedly fitted at the connection between the liquid injection pipe and the through groove.
[0007] As a further improvement of this utility model, connecting guide plates are fixedly provided on both sides of the first sealing plate, and the connecting guide plates are fastened to the reactor body by bolts.
[0008] As a further improvement of this utility model, the heat-conducting chamber is configured as a C-shaped chamber, and the internal heating fluid is heat carrier oil.
[0009] As a further improvement of this utility model, the heat-conducting chamber is fastened with multiple heat-conducting fins.
[0010] As a further improvement of this utility model, a through hole is provided on one side of the top of the first sealing plate, and the thermocouple is electrically connected to a temperature controller through an electrical connection wire passing through the through hole.
[0011] The beneficial effects of this utility model are as follows: A push rod motor is installed at the top of the first sealing plate. The output end of the first push rod is fixedly connected to the outer shell of the electric heating chamber. The top of the second sealing plate is also fixedly connected to the electric heating chamber. A thermocouple penetrating the second sealing plate is built into the electric heating chamber, and the thermocouple is controlled by a programmable logic controller. By pushing the motor to insert the heating component into the reaction liquid, heat is supplied to the heat-conducting chamber containing the heating fluid. Several heat-conducting fins fitted onto the outside of the heat-conducting chamber expand the heat-conducting area, preventing other factors from interfering with the reaction balance, increasing heat conduction efficiency, and reducing reaction temperature deviation.

It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0020] This utility model provides a dimethyl silicone oil mixing reactor with heat exchange function, including a reactor body 1 and a first sealing plate 2;
[0021] As attached Figure 1-4 As shown, a push rod motor 3 is fixedly installed on the top of the first sealing plate 2. The output end of the push rod motor 3 passes through the first sealing plate 2, and an electric heating chamber 4 is fixedly connected to the bottom of the output end. A second sealing plate 5 is fixedly installed at the bottom of the electric heating chamber 4. A through groove 7 is opened on one side of the first sealing plate 2 and the second sealing plate 5. A liquid injection pipe 8 is placed inside the through groove 7, and a sealing ring 9 is fixedly fitted at the connection between the liquid injection pipe 8 and the through groove 7. The liquid injection pipe 8 is a telescopic pipe with an inwardly recessable outer wall between the two sealing rings 9. The through groove 7 allows the liquid injection pipe 8 to pass through into the reactor body 1 for material conveying. Connecting guide plates 10 are fixedly installed on both sides of the first sealing plate 2. The connecting guide plates 10 are fastened to the reactor body 1 by bolts. The connecting guide plates 10 and bolts are used to enhance the stability of the structural connection. The first sealing plate 2 has a through hole 12 on one side of its top. The thermocouple is electrically connected to the temperature controller through an electrical connection wire passing through the through hole 12. The temperature controller is controlled by a PLC Smart 200 (programmable logic controller).
[0022] As attached Figure 1-3 As shown, the electric heating chamber 4 contains a thermocouple that penetrates the second sealing plate 5, and the bottom of the thermocouple is fixedly connected to the outer wall of multiple heat-conducting chambers 6. Each heat-conducting chamber 6 contains a heating fluid. The thermocouple heats the fluid within the cylindrical heat-conducting chamber 6 to achieve heat exchange. The heat-conducting chamber 6 is C-shaped, and the internal heating fluid is heat carrier oil; it has good thermal stability and low oxidation tendency. Multiple heat-conducting fins 11 are fastened to the heat-conducting chamber 6 to increase the heat conduction area within the vessel.
[0023] Working Principle: In practical implementation, the first sealing plate 2 is first fastened to the top of the reactor body 1 using connecting guide plates 10 and bolts located on both sides of the first sealing plate 2. Then, reaction liquid is injected into the reactor body 1 through the injection pipe 8. The push rod motor 3 is activated, causing its output end to move the electric heating chamber 4 and the second sealing plate 5 downwards until the reaction liquid submerges the heat-conducting chamber 6 and its outer wall heat-conducting fins 11. Since the central side of the injection pipe 8 is designed as a telescopic pipe with an inwardly recessable outer wall, the injection pipe 8 extends as the output end of the push rod motor 3 moves. By driving the PLC Smart 200, the thermocouple is activated to heat the heat carrier oil in the heat-conducting chamber 6, raising the temperature to 220°C. The heat is then evenly conducted to the reaction liquid through the heat-conducting chamber 6 and the heat-conducting fins 11.

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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
