Abstract
Description
Technical Field
[0001] This utility model relates to the field of chemical technology, and in particular to an intelligent temperature control device for a reaction vessel. Background Technology
[0002] Reactors are core equipment in chemical, pharmaceutical and materials synthesis, used to realize chemical reactions of materials under specific conditions. The main body is a closed container, which promotes the mixing of materials by stirring paddles, and is equipped with heating and cooling jackets or coils to precisely control the temperature. The materials include stainless steel, glass enamel or special alloys to adapt to harsh working conditions such as strong acid and high pressure.
[0003] Reactors require intelligent temperature control devices because they can precisely control the reaction temperature, avoiding side reactions or product quality degradation caused by temperature fluctuations. Intelligent systems can monitor and automatically adjust heating / cooling rates in real time to ensure the reaction proceeds under optimal conditions, improving efficiency and safety, reducing human intervention errors, and ensuring process stability. Existing reactor devices lack intelligent temperature control functions and rely heavily on manual adjustment of heating or cooling equipment, making it difficult to accurately match the reaction temperature requirements in real time. This can easily lead to temperature overshoot and large fluctuations, affecting product purity and yield, and even causing safety hazards. Upgrading to intelligent control can significantly improve process reliability and production efficiency. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0029] Example 1:
[0030] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides an intelligent temperature control device for a reaction vessel, including a base plate 1 and a support member 2. The support member 2 is provided on the top of the base plate 1. An oil storage member 3 is provided inside the support member 2. A vessel cavity 4 is provided inside the oil storage member 3. A sealing ring 5 is fixed on the top of the vessel cavity 4. A sealing member 6 is provided on the outside of the sealing ring 5. A vessel cover 7 is provided on one side of the sealing member 6. A stirring member 8 is provided on the top of the vessel cover 7. A stirring blade 9 is provided on the bottom of the stirring member 8. A control mechanism 10 is provided on the top of the vessel cover 7. An oil inlet pipe 11 is provided inside the oil storage member 3. A heating member 12 is provided at one end of the oil inlet pipe 11. A heat exchange member 13 is provided on one side of the heating member 12. A circulation mechanism 14 is provided on one side of the heat exchange member 13.
[0031] Two sets of sealing rings 5 are provided. One set is fixed to the bottom of the vessel cover 7, and the other set is fixed to the top of the vessel cavity 4. Fixing blocks 61 are fixed to the outer sides of both sets of sealing rings 5. Both sets of sealing rings 5 are existing technologies. The materials commonly used for sealing rings 5 are polytetrafluoroethylene, graphite, or metal-coated flexible fillers, which combine temperature resistance, corrosion resistance, and low friction characteristics. Their sealing principle is to use elastic deformation or pre-tightening force to ensure a tight seal between the sealing surface and the vessel cavity 4 and vessel cover 7, preventing heat transfer oil leakage and maintaining stable system pressure. An oil inlet is provided on the inner wall of the vessel cover 7. The design of the support component 2 ensures the stability of the reactor when processing chemical materials. The design of the oil storage component 3 allows for the storage of heat transfer oil, facilitating subsequent reactor maintenance. The internal chemical material processing chamber 4 is circulated and temperature controlled. The design of the sealing element 6 can prevent water leakage during the processing of chemical materials inside the chamber 4. The regulating mechanism 10 monitors the internal temperature of the chamber 4 in real time. When the temperature deviates from the set value, the regulating mechanism 10 can automatically adjust the power of the heating element 12 or start the heat exchange element 13 for heat exchange. The circulation mechanism 14 drives the heat transfer oil to flow in the heating element 12, the heat exchange element 13 and the oil storage element 3, and quickly transfer heat. This achieves the effect of intelligent temperature control when processing chemical materials in the reactor, avoiding the problem of difficulty in matching the reaction temperature requirements in real time, which can easily lead to temperature overshoot and large fluctuations, affecting the purity and yield of the product.
[0032] The control mechanism 10 includes a temperature monitor 101 and an actuator 102, which are respectively fixed to the top of the lid 7.
[0033] Temperature monitor 101 is embedded in the inner wall of the vessel lid 7, and the detection probe of temperature monitor 101 extends into the interior of vessel cavity 4. Temperature monitor 101 monitors the temperature inside vessel cavity 4 in real time and transmits the data to actuator 102. When the temperature deviates from the set value, actuator 102 automatically adjusts the heating power. Temperature monitor 101 and actuator 102 are existing technologies and are consistent with the temperature sensor and controller in the authorized application entitled "A Reactor Capable of Regulating Internal Temperature" with application number CN202421384529.3. They will not be described in detail here.
[0034] The circulation mechanism 14 includes a connecting pipe 141 disposed on one side of the heat exchanger 13, and one end of the connecting pipe 141 is connected to a circulation pump 142.
[0035] The oil outlet pipe 15 is connected to the water inlet of the circulating pump 142. When the circulating pump 142 is turned on, the circulating pump 142 guides the heat transfer oil to the connecting pipe 141 through the oil outlet pipe 15, which facilitates the subsequent guidance of the heat transfer oil to the heat exchanger 132 through the connecting pipe 141, so as to achieve the effect of temperature control for subsequent circulation of the heat transfer oil. The circulating pump 142 is a prior art technology. The circulating pump 142 is mostly made of high temperature and corrosion resistant alloy or cast steel, which is suitable for the high temperature environment of heat transfer oil. When working, the pump impeller rotates to generate centrifugal force, which pushes the heat transfer oil from the oil storage layer 32 to be drawn in through the oil outlet pipe 15. After being pressurized, it is transported to the heat exchanger 132 and the heater 122 through the connecting pipe 141 for heating or cooling. Then it circulates in the oil storage layer 32 through the oil inlet pipe 11 to form a closed loop of heat medium and achieve efficient heat exchange.
[0036] Example 2:
[0037] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0038] Specifically, the support member 2 includes a support base 21 fixed to the top of the base plate 1, and a support rod 22 is fixed to the top of the support base 21.
[0039] The base plate 1 can fix the support rod 22 through the support seat 21, which facilitates the subsequent support of the reactor to ensure the stability of the reactor when processing chemical materials.
[0040] Specifically, the support member 2 also includes a support plate 23 fixed to one end of the support rod 22, and a support sleeve 24 is fixed to one side of the support plate 23.
[0041] The support rod 22 can be fixed to the support sleeve 24 through the support plate 23, which facilitates subsequent support of the reactor to ensure the stability of the reactor when processing chemical materials.
[0042] Specifically, the oil storage component 3 includes a vessel body 31 fixed to the inner wall of the support sleeve 24, an oil storage layer 32 fixed to the inner wall of the vessel body 31, and the inner wall of the oil storage layer 32 fixed to the outer side of the vessel cavity 4.
[0043] The vessel body 31 can fix the oil storage layer 32. The heat transfer oil in the oil storage layer 32 circulates, which facilitates the subsequent temperature control of the chemical materials in the vessel cavity 4, so as to ensure the stability of the chemical materials during processing.
[0044] Specifically, the sealing element 6 includes two sets of fixing blocks 61 respectively fixed to the outside of the sealing ring 5, and the inner wall of the fixing block 61 is threaded with bolts 62.
[0045] The bolts 62 rotate along the threads on the inner walls of the two sets of fixing blocks 61. The two sets of fixing blocks 61 drive the two sets of sealing rings 5 to fit tightly together, facilitating sealing during subsequent chemical material processing and preventing chemical material leakage.
[0046] Specifically, the seal 6 also includes a turntable 63 fixed to one end of the bolt 62, and a nut 64 is threaded onto the outer side of the bolt 62.
[0047] By rotating the turntable 63, the bolt 62 is driven to rotate along the threads of the two sets of fixing blocks 61, so that the turntable 63 is in contact with the bottom of the fixing block 61. By rotating the nut 64 along the outside of the bolt 62, the nut 64 is in contact with the bottom of the fixing block 61, so as to achieve a tight fit between the two sets of sealing rings 5, which facilitates sealing during subsequent chemical material processing and prevents chemical material leakage.
[0048] Example 3:
[0049] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0050] Specifically, the stirring component 8 includes a motor 81 fixed to the top of the lid 7, and a stirring rod 82 is fixed to the output end of the motor 81, with the outer side of the stirring rod 82 fixed to the inner wall of the stirring blade 9.
[0051] The lid 7 can fix the motor 81. When the motor 81 is turned on, the motor 81 drives the stirring rod 82 to rotate. The stirring rod 82 and the stirring blade 9 stir the chemical materials in the vessel cavity 4, so as to achieve the effect of processing the chemical materials, avoid local overheating or side reactions in the vessel cavity 4, promote solid-liquid suspension and gas-liquid dispersion, improve mass transfer efficiency, and enhance heat exchange.
[0052] Specifically, the heating element 12 includes a connecting pipe 121 connected to one end of the oil inlet pipe 11, and one end of the connecting pipe 121 is connected to a heater 122.
[0053] The heat transfer oil is transported to the heat exchanger 132 and the guide pipe 131 through the connecting pipe 141. The heat transfer oil is heated in the heater 122 through the guide pipe 131, and then the heat transfer oil is guided to the oil inlet pipe 11 through the connecting pipe 121 for subsequent heating of the heat transfer oil. The heater 122 is a prior art technology. The material of the heater 122 is usually carbon steel, stainless steel or high temperature resistant alloy, which is suitable for the high temperature and corrosive environment of the heat transfer oil. Its principle is that the electric heating tube and the steam coil convert electrical energy or steam heat energy into heat energy, and heat the heat transfer oil through direct contact or thermal radiation. The circulating pump 142 drives the hot oil to transfer heat to the reaction vessel.
[0054] Specifically, the heat exchanger 13 includes a guide pipe 131 that is connected to the water inlet of the heater 122. One end of the guide pipe 131 is fixed with a heat exchanger 132, and the water inlet of the heat exchanger 132 is connected to one end of the connecting pipe 141.
[0055] The heat transfer oil is transported to the heat exchanger 132 through the connecting pipe 141, so that the heat exchanger 132 can exchange heat with the heat transfer oil. The heat transfer oil is heated in the heater 122 through the guide pipe 131 to facilitate subsequent heat exchange of the heat transfer oil. The heater 122 is a prior art technology. The main body of the heater 122 is mostly made of carbon steel, stainless steel or high temperature resistant alloy to resist high temperature oxidation and corrosion of the heat transfer oil. It conducts heat through the pipe wall. When the heat transfer oil flows through the heating pipe, it absorbs heat energy and heats up. The heat is transferred to the reaction vessel by convection circulation to achieve efficient heat exchange.
[0056] Specifically, the water inlet of the circulating pump 142 is connected to the oil outlet pipe 15, and the outer side of the oil outlet pipe 15 is fixed to the inner wall of the vessel body 31.
[0057] The design of the oil outlet pipe 15 allows the heat transfer oil to be easily connected to the circulation pump 142, facilitating subsequent circulation and temperature control of the heat transfer oil within the oil storage layer 32, thereby improving the stability of the device during the processing of chemical materials.
[0058] In operation, the operator first disconnects the connecting pipe 121 and injects the heat transfer oil into the oil storage layer 32 through the oil inlet pipe 11. After completion, the connecting pipe 121 is reconnected to the oil inlet pipe 11. When chemical materials need to be added, they are injected into the vessel cavity 4 through the feed port at the top of the vessel lid 7. The motor 81 is then turned on, driving the stirring rod 82 to rotate. The stirring rod 82 and the stirring blade 9 stir the chemical materials in the vessel cavity 4 evenly. The circulation pump 142 is then turned on, and the temperature inside the vessel cavity 4 is monitored in real time by the temperature monitor 101. The data is transmitted to the actuator 102. When the temperature deviates from the set value, the actuator will automatically activate the temperature control mechanism. When the temperature is too low, the actuator 102 automatically adjusts the power of the heater 122. When the temperature is too high, the heat exchanger 132 is started for heat exchange. The centrifugal force generated by the rotation of the impeller of the circulating pump 142 pushes the heat transfer oil from the oil storage layer 32 through the oil outlet pipe 15. After being pressurized, it is transported to the heat exchanger 132 and the heater 122 through the connecting pipe 141 for heating or cooling. Then it circulates in the oil storage layer 32 through the oil inlet pipe 11, forming a closed loop of heat medium and realizing efficient heat exchange. This achieves the effect of intelligent temperature control when processing chemical materials in the reactor, avoiding the problem that large temperature fluctuations can easily lead to uncontrolled reaction, such as side reactions or product decomposition, reducing product purity and yield.
