[0001] This utility model relates to the field of chemical engineering and technology, and in particular to a reaction vessel with rapid cooling and heating functions. Background Technology

[0002] In many industrial sectors such as chemical, pharmaceutical, and food processing, reaction vessels are core reaction equipment, and the accuracy and efficiency of their temperature control directly affect product quality and production efficiency. Many chemical reactions require specific temperature conditions, and often necessitate rapid heating or cooling operations during the reaction process to meet the different needs of each reaction stage.

[0003] Existing technologies for reactors have significant limitations in temperature control. Some reactors only have a single heating or cooling function; reversing temperature control requires external equipment, which is cumbersome and time-consuming. Even reactors with both heating and cooling functions suffer from inadequate heat exchange structure design, poor fit between heating and cooling elements and the reactor body, and low heat transfer efficiency, resulting in slow heating or cooling rates that cannot meet the requirements of rapid temperature switching in production. Furthermore, the heating or cooling components of some reactors are not securely installed and are prone to displacement during long-term use, further affecting the stability of heat exchange efficiency and causing inconvenience to industrial production. Therefore, a reactor with rapid heating and cooling capabilities is proposed. Utility Model Content

Detailed Implementation

[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] See Figure 1-4 As shown in the figure, this embodiment of a reactor with rapid cooling and heating functions includes a reactor body 1. A limiting ring 2 is welded to the lower end of the outer side of the reactor body 1. A heating sleeve 3 is fitted on the outer side of the reactor body 1. A control box 4 is welded to the outer side of the heating sleeve 3. A refrigerator 5 is connected to the heating sleeve 3 through a pipe. A reactor cover 6 is bolted to the upper end of the reactor body 1. A stirring motor 7 is welded to the center of the reactor cover 6. An inspection manhole 8 is welded into a through hole near the edge of the surface of the reactor cover 6. A feeding port 9 is welded into another through hole near the edge of the surface of the reactor cover 6. A first discharge port 10 is welded into a through hole near the edge of the lower surface of the reactor body 1. A second discharge port 11 is welded into another through hole near the edge of the lower surface of the reactor body 1. Multiple support legs 12 are evenly distributed and welded to the lower surface of the reactor body 1 near the edge.

[0020] Specifically, the vessel body 1, as the core container of the reaction, is used to contain the materials to be reacted and to provide reaction space for chemical reaction or physical mixing. Its material must meet the requirements of temperature resistance, pressure resistance and corrosion resistance required by the reaction.

[0021] The lid 6 is bolted to the upper end of the vessel body 1, which seals the vessel body 1 and prevents material leakage during the reaction process. It also provides a mounting base for the stirring motor 7, inspection manhole 8, and feed port 9.

[0022] The limiting ring 2 is welded to the lower outer side of the vessel body 1 to limit the heating sleeve 3, prevent the heating sleeve 3 from sliding down the outer side of the vessel body 1, and ensure that the heating sleeve 3 is in the preset working position.

[0023] Heating jacket 3 is fitted on the outside of the vessel body 1 and is a key component for realizing heating and cooling functions. It exchanges heat with the vessel body 1 through its internal structure to quickly regulate the temperature of the vessel body.

[0024] The control box 4 is welded to the outside of the heating jacket 3 and connected to the front end of the spiral electric heating tube 303 inside. It is used to control the working state of the spiral electric heating tube 303 and realize precise control of the heating process.

[0025] The stirring motor 7 is welded to the center of the vessel lid 6. When working, it drives the stirring components inside the vessel (not individually labeled). It is usually driven by the motor to extend into the vessel and rotate, so that the materials inside the vessel are fully mixed and the reaction is carried out uniformly.

[0026] The inspection manhole 8 is welded into the through hole near the edge of the surface of the vessel cover 6, which facilitates the operator to inspect, repair or clean the inside of the vessel body 1;

[0027] The feed port 9 is welded into another through hole near the edge of the surface of the vessel cover 6, and is used to add the materials required for the reaction into the vessel body 1;

[0028] The No. 1 discharge port 10 and the No. 2 discharge port 11 are both welded into the through hole near the edge on the lower surface of the vessel body 1. They are used to discharge the material after the reaction is completed from the vessel body 1. The two discharge ports can be flexibly selected for use as needed, or used to discharge materials in different states separately.

[0029] Support legs 12 are evenly welded to the lower surface of the vessel body 1 near the edge to support the entire reactor, keep the vessel body 1 in a stable position, and prevent the vessel body 1 from shaking during the reaction.

[0030] See appendix Figure 1-4 As shown, the heating sleeve 3 includes an outer sleeve 301 that is sleeved on the outside of the vessel body 1. The outer sleeve 301 is located above the limiting ring 2. An inner copper sleeve 302 is welded to the inner side of the outer sleeve 301. The inner wall of the inner copper sleeve 302 is in contact with the outside of the vessel body 1.

[0031] The outer side of the embedded copper sleeve 302 is provided with a double helical groove.

[0032] The heating sleeve 3 also includes a spiral electric heating tube 303 that is fitted into one of the spiral grooves on the outside of the inner copper sleeve 302, a spiral cooling tube 304 that is fitted into another spiral groove on the outside of the inner copper sleeve 302, and two handles 305 that are welded to the outside of the outer sleeve 301 near the upper end.

[0033] The front end of the spiral electric heating tube 303 is fixedly connected to the inside of the control box 4, and the spiral cooling tube 304 is fixedly connected to the inlet and outlet water pipes of the refrigeration unit 5.

[0034] The outer side of the outer sleeve 301 is welded to the front end of the control box 4.

[0035] Specifically, the outer sleeve 301, as the outer layer structure of the heating sleeve 3, plays a role in protecting and fixing the internal embedded copper sleeve 302, spiral electric heating tube 303 and spiral cooling tube 304.

[0036] The inner wall of the embedded copper sleeve 302 is attached to the outer side of the vessel body 1. It utilizes the high thermal conductivity of copper to efficiently transfer heat or cold. The double spiral groove on its outer side is used to fix the spiral electric heating tube 303 and the spiral cooling tube 304.

[0037] The spiral electric heating tube 303 is inserted into a spiral groove of the embedded copper sleeve 302. It generates heat by energizing the material inside the vessel, and then transfers the heat to the vessel body 1 through the embedded copper sleeve 302.

[0038] The spiral cooling pipe 304 is inserted into another spiral groove of the embedded copper sleeve 302 and connected to the refrigerator 5. The low-temperature cold water provided by the refrigerator 5 enters the spiral cooling pipe 304 and absorbs the heat of the material in the vessel 1 to achieve cooling. Then the cold water flows back to the refrigerator 5 for circulation.

[0039] The handle 305 is welded to the outside of the outer sleeve 301 near the upper end, making it convenient for operators to carry or move the heating sleeve 3.

[0040] See appendix Figure 1-3 As shown, the refrigeration unit 5 is equipped with a control panel and a handle at the top, and casters are welded to the four corners of its bottom surface.

[0041] Specifically, the refrigeration unit 5 is connected to the spiral cooling pipe 304 through pipes, providing cooling capacity to the spiral cooling pipe 304. It is the core equipment of the refrigeration system. The control panel at the top is used to adjust the refrigeration parameters, the handle is easy to move, and the casters on the bottom facilitate the adjustment of the refrigeration unit's position.

[0042] The operation process of this utility model is as follows: When adding materials, open the sealing cover of the feeding port 9 and slowly add the materials to be reacted into the reactor body 1 through the feeding port 9. Take care to avoid spilling the materials. After the materials are added, close the sealing cover of the feeding port 9 to ensure that the reactor body 1 is sealed.

[0043] When starting the agitator, turn on the agitator motor 7. The motor will drive the agitator inside the vessel to rotate. Observe the agitation status to ensure that the materials are mixed evenly. If abnormal noise or jamming occurs, stop the machine immediately for inspection.

[0044] In the heating operation, when the temperature needs to be increased, the target temperature is set through the control box 4, the spiral electric heating tube 303 is activated, and the heat is transferred to the vessel 1 through the embedded copper sleeve 302 to heat the material in the vessel 1. The control box 4 monitors the temperature in real time and automatically maintains a constant temperature after the set value is reached.

[0045] In the refrigeration operation, when cooling is required, the heating function is turned off, the refrigeration unit 5 is started, and the refrigeration temperature is set through the control panel. The low-temperature cold water generated by the refrigeration unit 5 enters the spiral cooling pipe 304, absorbs the heat of the vessel body 1, and is quickly cooled through the embedded copper sleeve 302. The cold water is circulated back to the refrigeration unit 5 for continuous cooling until the target temperature is reached.

[0046] When switching between cooling and heating, the heating or cooling mode can be quickly switched through the control box 4 and the control panel of the refrigerator 5 according to the needs of the reaction process, and the high thermal conductivity of the embedded copper sleeve 302 is used to achieve rapid temperature adjustment.

[0047] During process monitoring, the reaction status of the material inside the vessel 1 can be observed periodically through the inspection manhole 8. However, attention should be paid to the safety regulations when opening the manhole under high temperature and high pressure conditions, and the parameter displays of the control box and the refrigeration unit should be continuously monitored.

[0048] When the material is discharged, the No. 1 discharge port 10 and the No. 2 discharge port 11 are connected to the conveying pipe with valves. Depending on the material state, the No. 1 discharge port 10 or the No. 2 discharge port 11 is selected, the corresponding valve is opened, and the reacted material is discharged to the designated container. If there is residual material, it can be discharged through the other discharge port.

[0049] 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.
