Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a reaction vessel. Background Technology

[0002] A reaction vessel is a device used to mix materials, allowing different materials to combine and undergo physical and chemical changes, thereby obtaining a desired mixture or reactant.

[0003] Currently, reaction vessels require heating during operation. Heating accelerates the movement of molecules, atoms, and other microscopic particles in the reaction system, increasing the frequency and energy of collisions. This allows more molecules to overcome activation energy barriers, effectively increasing the rate of chemical reactions and shortening the time required to reach equilibrium or complete the reaction. Existing reaction vessels typically employ resistance wire heating, designing a double-layered structure with a jacket between the inner and outer layers. Resistance wires are placed within the jacket; when current passes through the resistance wires, electrical energy is converted into heat energy, thereby heating the materials inside the reaction vessel. This method offers advantages such as rapid heating, high temperature control precision, and ease of operation. However, during resistance wire heating, heat is concentrated primarily around the resistance wire, easily leading to localized overheating while areas further away remain cooler, creating a significant temperature gradient and uneven heating. Furthermore, the resistance wires, operating under prolonged high temperatures, are prone to aging and breakage, requiring maintenance. Since the resistance wires are installed inside the jacket, disassembly is difficult, further complicating maintenance. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Please see Figure 1-3 As shown, a reaction vessel includes an outer vessel body 1 and an inner vessel body 2 disposed inside the outer vessel body 1. Both the outer vessel body 1 and the inner vessel body 2 have conical bottoms for easy discharge. A drive motor 14 is installed at the top of the inner vessel body 2. A stirring shaft 15 extending into the inner vessel body 2 is connected to the output end of the drive motor 14, and a stirring paddle 16 is connected to the stirring shaft 15. After material is added into the inner vessel body 2, the drive motor 14 can be started to drive the stirring shaft 15 to rotate, thereby causing the stirring paddle 16 to rotate accordingly, thus enabling… The reactor is capable of efficiently stirring materials. A feeding port 3 is located at the top of the inner vessel 2, allowing materials to be added into the inner vessel 2. A discharge pipe 4 is located at the bottom of the inner vessel 2. A jacket 5 is formed between the outer vessel 1 and the inner vessel 2. An input pipe 6, communicating with the inside of the jacket 5, is located on the side wall of the outer vessel 1. The input pipe 6 is used to input the heating medium into the jacket 5. The heating medium can be hot water or hot oil. Before using the reactor, the heating medium can be input into the jacket 5 through the input pipe 6. The jacket 5 provides space for the circulation of the heating medium, increases the heating area, and allows heat to be transferred more evenly to the reactants, thereby improving heating efficiency. Furthermore, the heater allows the heating element 8 to be powered on during use, heating the heating medium to the required temperature. The heating medium conducts heat, ensuring even heating of the materials within the inner vessel 2 and preventing temperature differences, thus guaranteeing heating uniformity. An output pipe 12 for discharging the heating medium is installed on the bottom wall of the outer vessel 1, allowing the heating medium to be discharged when the reactor is not in use, preventing prolonged storage within the jacket 5 and thus preventing corrosion of the inner vessel 2 and outer vessel 1 sidewalls. A temperature sensor 13, extending into the jacket 5, is installed on the side wall of the outer vessel 1. This sensor monitors the temperature of the heating medium within the jacket 5 in real time and transmits the temperature signal to the controller, preventing the heating medium temperature from becoming too high or too low, thereby achieving precise temperature maintenance and control and ensuring that the chemical reaction of the materials proceeds in a suitable temperature environment.

[0020] Please see Figure 1 , Figure 4As shown, several heaters are evenly arranged circumferentially on the side wall of the outer vessel 1. Each heater includes a connector 7 connected to a power source, and a heating element 8 is installed on the connector 7. Several connecting pipes 9 are evenly arranged circumferentially on the side wall of the outer vessel 1. The connecting pipes 9 are inclinedly arranged on the side wall of the outer vessel 1 and communicate with the inside of the jacket 5. The heating element 8 passes through the connecting pipe 9 and extends into the inside of the jacket 5. A threaded pipe 10 is installed on the connector 7. An external thread structure is formed on the outer side wall of the threaded pipe 10, and an internal thread structure matching the external thread structure is formed on the inner side wall of the connecting pipe 9. Therefore, when maintenance of the heater is required, simply disconnect the power source, then screw on the connector 7 to unscrew the threaded pipe 10 from the connection. The heating element 8 is pulled out from the jacket 5, thus disassembling the heater and facilitating its maintenance without disassembling the reactor. After the operation is completed, the heating element 8 can be inserted through the connecting pipe 9 and into the jacket 5. Then, the threaded pipe 10 is screwed into the connecting pipe 9. The heater is securely installed through the threaded connection between the threaded pipe 10 and the connecting pipe 9. The operation is relatively simple, making the maintenance of the heater more convenient. Each connector 7 is equipped with a grip knob 11. By gripping and turning the grip knob 11, the threaded pipe 10 can be screwed into or out of the connecting pipe 9, thus assembling and disassembling the heater. The grip knob 11 can also serve as a force point for operation, making the operation easier and less strenuous.
