Description

Technical Field

[0001] This utility model relates to the field of cyclohexanol processing technology, specifically an energy-saving cyclohexanol hydration reactor. Background Technology

[0002] Cyclohexanol hydration refers to the chemical reaction between cyclohexane and water molecules, through which cyclohexanol can be prepared. The chemical process of hydration for the preparation of cyclohexanol has many advantages, such as short reaction time, wide selection of raw materials, and environmental friendliness and non-toxicity. With the continuous increase in market demand, this method has broad application prospects in industry and can be applied to multiple fields such as organic synthesis, dyes, and plastics.

[0003] A search revealed a thermally efficient cyclohexanol hydration reactor with publication number CN205965824U, comprising a first reactor and a second reactor. This reactor addresses the problem of low conversion rates in conventional reactors and the need to recover and reuse large quantities of unreacted cyclohexane. However, this practical application uses a single stirring mechanism to agitate the materials, resulting in poor stirring uniformity, which affects the reaction rate. Furthermore, the reaction products cannot be quickly removed after production. Therefore, we propose an energy-saving cyclohexanol hydration reactor. Utility Model Content

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.

[0022] This invention provides an improved energy-saving cyclohexanol hydration reactor. Please refer to [link / reference]. Figure 1-Figure 3 The system includes: a cylinder 1, with a circular heating plate 2 embedded inside the lower end of the cylinder 1; a sealing cover 3 hinged to one outer wall of the cylinder 1; a transparent observation window 4 located in the middle of the sealing cover 3; the observation window 4 being rotatably connected to the cylinder 1 via the sealing cover 3, allowing operators to observe the reaction process; a bolt 5 fixed to the other end of the sealing cover 3; a retainer 6 fixed at the connection between the cylinder 1 and the bolt 5; and a pin connection between the bolt 5 and the cylinder 1 via the retainer 6, which securely seal the sealing cover 3 to one side of the cylinder 1 to prevent material spillage during the reaction; a temperature and pressure sensor 7 bolted to the outer wall of the top of the cylinder 1, allowing operators to monitor the internal reaction temperature and pressure; a top cover 8 hinged to one outer wall of the top of the cylinder 1; and a motor 9 bolted to the lower surface of the top of the cylinder 1, with the motor 9 aligned with the central axis of the cylinder 1. The motor 9 drives the turntable 10 and the stirring screw 12 to stir the materials through the output shaft. The turntable 10 is mounted on the outer wall of the motor 9 through bearings. The turntable 10 is rotatably connected to the cylinder 1 through the gear set 11 and the output shaft of the motor 9. The output shaft of the motor 9 is connected to the gear set 11, and the gear set 11 is embedded in the lower end of the turntable 10 through the rotating shaft. The stirring screw 12 is fixed on the lower surface of the other end of the gear set 11. The stirring screw 12 is rotatably connected to the turntable 10 through the gear set 11 and the output shaft of the motor 9. The stirring screw 12 and the turntable 10 are used to stir and mix the materials of the cyclohexanol hydration reaction inside the cylinder 1 under the drive of the output shaft of the motor 9, which accelerates the reaction process. Moreover, the multi-stage stirring mechanism mixes more evenly and has a higher reaction rate than the single stirring method. The reaction products can be quickly taken out through the opened sealed side cover 3, which improves production efficiency.

[0023] Please see Figure 1-Figure 2An energy-saving cyclohexanol hydration reactor includes: a retaining ring 13 fixed on the inner surface of the upper end of a cylindrical body 1; a top cover 8 connected to the cylindrical body 1 by the retaining ring 13; an arc-shaped sealing gasket 14 laid on the upper surface of the retaining ring 13; and a sealing structure formed between the top cover 8 and the cylindrical body 1 by the sealing gasket 14 and the retaining ring 13. The top cover 8 is closed at the upper end of the cylindrical body 1 by the retaining ring 13 and the sealing gasket 14, preventing material overflow during the reaction inside the cylindrical body 1. The easily openable top cover 8 also allows operators to add reactants or catalysts as needed during the reaction process, making it convenient to use.

[0024] Please see Figure 1-Figure 2 and Figure 4 An energy-saving cyclohexanol hydration reactor includes: a universal wheel 15 bolted to the lower outer wall of a cylindrical body 1 for easy movement of the cylindrical body 1; a support column 16 fixed to the lower outer wall of the cylindrical body 1; the universal wheel 15 and the support column 16 being symmetrically positioned about the central axis of the cylindrical body 1; a lifting foot 17 threadedly fitted to the lower outer wall of the support column 16; a rubber pad 18 adhered to the lower outer wall of the lifting foot 17; and the pad 18 forming a telescopic connection with the support column 16 via the lifting foot 17; the lifting foot 17 is threaded to the lower end of the support column 16 for raising and lowering; when the cylindrical body 1 is placed in the working environment, the operator can rotate the lifting foot 17 to adjust it, so that the lifting foot 17 makes stable contact with the supporting surface through the lower pad 18, so that the lifting foot 17 can provide stable and stable support for the cylindrical body 1 even on uneven working surfaces, ensuring the stability of the cylindrical body 1 during operation.

[0025] Working Principle: For this type of energy-saving cyclohexanol hydration reactor, the operator first pushes the reactor cylinder 1 onto a stable, level working surface using casters 15. If the working surface is uneven, the support height can be adjusted by rotating the lifting feet 17 at the bottom of the support column 16. The lifting feet 17, through the pad 18, increase the static friction between themselves and the support surface, improving the stability of the cylinder 1 after placement and preventing the cylinder 1 from shaking during operation, which would affect the reaction stability. Then, the operator seals the sealing side cover 3 on one side of the cylinder 1 using bolts 5 and seat 6 to prevent the reactants in the cylinder 1 from overflowing from the gap between the sealing side cover 3 and the cylinder 1 during the reaction. Finally, the operator removes the materials required for the reaction from... Pour the contents into the cylinder 1 through the opened top cover 8, and close the top cover 8 using the retaining ring 13 and sealing gasket 14. The operator starts the motor 9, which drives the gear set 11 to rotate through the output shaft. The gear set 11 drives the turntable 10 and the stirring screw 12 to rotate inside the cylinder 1. The material is stirred by the multi-stage stirring mechanism, and the material is heated by the heating plate 2, thereby increasing the internal pressure of the cylinder 1. This accelerates the cyclohexanol hydration reaction process and increases the reaction rate. Finally, the operator can monitor the reaction process through the observation window 4 and monitor the temperature and pressure of the reaction through the temperature and pressure sensor 7, which allows the operator to adjust the reaction environment. The product after the reaction is completed can be quickly discharged through the opened sealed side cover 3, improving the production rate.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
