[0025] This invention provides a reaction vessel with a heat-insulating cavity formed between the inner and outer walls of the vessel body, surrounding the cavity. The heat-insulating liquid is introduced and removed via an inlet pipe and an outlet valve, reducing heat loss from the material within the cavity and providing initial heat preservation.

[0038] Please refer to Figures 1 to 4 An embodiment of this utility model provides a reaction vessel, comprising:

[0039] The vessel body 1 has an inner cavity 11, and a discharge valve 2 connected to the inner cavity 11 is provided at the bottom of the vessel body 1; the inner cavity 11 is a cavity used to load materials and provide a reaction chamber for the materials, and the product obtained after the reaction can be discharged from the discharge valve 2.

[0040] In an optional embodiment, the vessel body 1 is a container with double walls, and an insulating cavity 12 for storing insulating liquid is formed between the inner wall and the outer wall of the vessel body 1. The insulating cavity 12 surrounds the periphery of the inner cavity 11. That is, the inner cavity 11 is surrounded by the inner wall of the vessel body 1, while the insulating cavity 12 is located in the annular region between the inner wall and the outer wall of the vessel body 1.

[0041] The outer wall of the vessel body 1 is provided with an inlet pipe 3 that communicates with the heat preservation cavity 12, and the bottom of the vessel body 1 is provided with an outlet valve 4 that communicates with the heat preservation cavity 12.

[0042] A stirring device 5 is provided on the vessel body 1. The stirring device 5 is used to stir the material in the inner cavity 11 so that the material can be fully contacted and mixed evenly, thereby improving the reaction efficiency of the material.

[0043] The first electric heating device 6 is installed in the inner cavity 11 of the vessel body 1, and is used to heat the material in the inner cavity 11 to a first preset temperature, so that the material is maintained within the temperature range required for the reaction. The first preset temperature is adaptively set according to the type of material, and this embodiment does not specifically limit it.

[0044] The second electric heating device 7 is installed in the insulation cavity 12 and is used to heat the insulation liquid to the second preset temperature.

[0045] The second preset temperature is higher than the first preset temperature.

[0046] In this embodiment, by forming a heat-insulating cavity 12 between the inner and outer walls of the vessel body 1 and surrounding the periphery of the inner cavity 11, and by using the inlet pipe 3 and outlet valve 4 to allow the heat-insulating liquid to enter and exit, the heat loss of the material in the inner cavity 11 can be reduced, thus achieving a preliminary heat-insulating effect. The stirring device 5 can uniformly mix the material in the inner cavity 11, avoiding excessively high or low local temperatures, and helping the material to approach the optimal temperature required for the reaction as a whole, improving the uniformity and stability of the reaction, thereby improving the reaction efficiency and product quality to a certain extent. The first electric heating device 6 heats the material in the inner cavity 11 to a first preset temperature, and the second electric heating device 7 heats the heat-insulating liquid to a second preset temperature higher than the first preset temperature. The dual electric heating devices can create a temperature difference between the material and the heat-insulating liquid, allowing heat to be transferred from the heat-insulating liquid to the material, compensating for the heat loss of the material due to heat dissipation, maintaining the material within the temperature range required for the reaction, improving the reaction efficiency of the material, and thus improving the quality and yield of the product.

[0047] In an optional embodiment, the temperature difference between the material and the insulating liquid is set in the range of 5°C to 10°C, that is, the second preset temperature is 5°C to 10°C higher than the first preset temperature. This temperature difference range can effectively reduce heat loss, ensure stable temperature inside the cavity, and achieve good insulation effect; it also avoids excessive thermal stress on the vessel wall due to sudden temperature changes, thus effectively extending the service life of the vessel 1. In addition, a smaller temperature difference can prevent heat transfer from being too rapid, avoid local overheating of the material in the inner cavity 11, ensure the stability and controllability of the reaction process, and improve product quality.

[0048] In actual use, the insulating liquid is introduced into the insulating cavity 12 through the inlet pipe 3. Under the heating action of the second electric heating device 7, the insulating liquid continuously heats up and eventually reaches the second preset temperature, thereby achieving the insulating effect on the inner cavity 11. In some cases, the insulating liquid can also be heated externally first, and then introduced into the insulating cavity 12. In this case, the second electric heating device 7 may not play a heating role, but only a heat preservation role, thereby reducing the energy consumption of the reactor system.

[0049] After the reaction is complete, the outlet valve 4 can be opened to quickly discharge the high-temperature insulating liquid from the insulation chamber 12, thereby achieving rapid heat dissipation and cooling of the vessel body 1. In some cases, after the high-temperature insulating liquid is discharged, low-temperature cooling liquid can be introduced into the insulation chamber 12 through the inlet pipe 3. The low-temperature cooling liquid exchanges heat with the vessel body 1, further increasing the cooling rate of the vessel body 1, thereby improving the equipment's turnover efficiency, enabling faster production of the next batch, and also reducing the risk of injury to operators due to contact with high-temperature equipment.

[0050] Optionally, the aforementioned insulating liquid includes, but is not limited to, water, oil, and water-oil mixtures.

[0051] In one specific embodiment, please refer to Figure 1 and Figure 2 The outer walls and bottom walls of the vessel body 1 extend outwards away from the inner cavity 11 to form a heat-insulating cavity 12, which semi-encloses the outer perimeter of the inner cavity 11. Understandably, the semi-enclosed nature of the heat-insulating cavity 12 allows the heat-insulating liquid in the cavity 12 to provide heat to the inner cavity 11 from multiple directions, ensuring uniform heating of the inner cavity 11 walls and preventing localized overheating or underheating, thus guaranteeing temperature uniformity in different areas of the material within the inner cavity 11. Furthermore, the semi-enclosed nature of the heat-insulating cavity 12 increases the contact area between the heat-insulating liquid and the outer wall of the inner cavity 11, facilitating more efficient heat transfer to the inner cavity 11 and improving heat exchange efficiency.

[0052] For example, such as Figure 1 and Figure 2 As shown, the vessel body 1 can be cylindrical, with an internal hollow cavity 11. In this case, the heat preservation cavity 12 has a U-shaped cross-section in the vertical direction AA and an annular cross-section in the horizontal direction. In other cases, the vessel body 1 can also be a regular column such as a cuboid, or other irregular irregular column.

[0053] In one specific embodiment, an insulation layer 8 is also provided on the cavity wall of the insulation cavity 12 away from the inner cavity 11. The insulation layer 8 may include one or more layers of inorganic fiber insulation layer, ceramic insulation layer, and foam plastic insulation layer.

[0054] In this embodiment, by providing an insulation layer 8 on the side wall of the insulation cavity 12 away from the inner cavity 11, the insulation layer 8 will not affect the heat exchange efficiency between the insulation liquid and the material, and can also effectively reduce the heat loss of the insulation liquid, so that the insulation liquid can be more stably maintained at the second preset temperature, thereby further improving the insulation effect of the insulation liquid on the material, while reducing the energy consumption of the second electric heating device 7.

[0055] Alternatively, the inorganic fiber insulation layer may include a glass wool layer, a rock wool layer, etc.

[0056] For example, the foam insulation layer may be a polyurethane foam layer.

[0057] See Figure 3 As shown, in one specific embodiment, a first temperature sensor 9 is also provided in the inner cavity 11 for detecting the temperature of the material. A second temperature sensor 10 is also provided in the insulation cavity 12 for detecting the temperature of the insulation liquid.

[0058] In one specific embodiment, the reactor may further include: a control panel 14 and a power module (not shown in the figure), wherein the power module is electrically connected to the first electric heating device 6 and the second electric heating device 7; the control panel 14 is connected to the first temperature sensor 9, the second temperature sensor 10 and the power module respectively, and is used to disconnect or connect the circuit between the power module and the first electric heating device 6 and the second electric heating device 7.

[0059] In this embodiment, the control panel 14 is connected to the first temperature sensor 9, the second temperature sensor 10, and the power module. The control panel 14 can obtain the temperature of the material in the inner cavity 11 through the first temperature sensor 9, and the control panel 14 can obtain the temperature of the insulating liquid in the insulation cavity 12 through the second temperature sensor 10. When the temperature of the material is lower than the first preset temperature, the circuit between the power module and the first electric heating device 6 is connected, and the first electric heating device 6 continues to heat the material. When the temperature of the material is detected to reach the first preset temperature, the control panel 14 sends a control signal to the power module, causing the power module to disconnect from the first electric heating device 6, thereby stopping the first electric heating device 6 from heating the material and maintaining the material at the first preset temperature. Similarly, when the temperature of the insulation liquid is lower than the second preset temperature, the circuit between the power module and the second electric heating device 7 is connected, and the second electric heating device 7 continues to heat the insulation liquid; when the temperature of the insulation liquid is detected to reach the second preset temperature, the control panel 14 sends a control signal to the power module, causing the power module to disconnect from the electrical connection with the second electric heating device 7, thereby causing the second electric heating device 7 to stop heating the insulation liquid, so that the insulation liquid is maintained at the second preset temperature.

[0060] Therefore, this embodiment achieves automated control of material temperature and insulation liquid temperature, reducing the workload of operators and providing a better user experience. During use, the first and second preset temperatures can be set via the control panel 14.

[0061] For example, control panel 14 can be Figure 3 The button-type control panel shown may have buttons 141, such as a "heating on" button, a "heating off" button, and a "temperature adjustment" button. The control panel 14 integrates a controller, which is connected to the aforementioned buttons 141, the first temperature sensor 9, the second temperature sensor 10, and the power module. The controller may be, for example, a microcontroller chip (MCU), an application-specific integrated circuit chip (ASIC), or a field-programmable gate array chip (FPGA).

[0062] In practical applications, the power module can be integrated into the control panel 14. The controller and the power module can be connected to other components via cables 15 for signal or electrical connections. Additionally, the power module can be electrically connected to the first temperature sensor 9 and the second temperature sensor 10 to provide the necessary power for their normal operation.

[0063] In one specific embodiment, both the first electric heating device 6 and the second electric heating device 7 include an electric heating wire or an electric heating tube electrically connected to the power supply module.

[0064] For example, please refer to Figure 2 and Figure 3 The first electric heating device 6 includes an electric heating tube disposed on the wall of the inner cavity 11, and the second electric heating device 7 includes an electric heating wire disposed on the wall of the heat preservation cavity 12.

[0065] Preferably, the electric heating tube surrounds and covers the cavity wall of the inner cavity 11 around the circumference of the vessel body 1, and the electric heating wire surrounds and covers the cavity wall of the insulation cavity 12 around the circumference of the vessel body 1, thereby enabling the electric heating tube and the electric heating wire to heat the material and the insulation liquid at a higher rate, effectively improving production efficiency.

[0066] In one specific embodiment, the top of the vessel body 1 also has an openable cover plate 16, and a sealing ring 161 is provided on the bottom edge of the cover plate 16.

[0067] For example, please refer to Figure 2 and Figure 4 In this embodiment, the top of the vessel body 1 has a feed inlet 13 that communicates with the inner cavity 11. When the cover plate 16 is in the closed state, the cover plate 16 blocks the feed inlet 13, and the cover plate 16 is sealed to the edge of the feed inlet 13 through the sealing ring 161 at the bottom edge. When the reaction operation is to be carried out, the cover plate 16 can be switched to the open state, at which time the feed inlet 13 is exposed, and the operator can add materials to the inner cavity 11 of the vessel body 1 through the feed inlet 13. After the material is added, the cover plate 16 is closed again, so that the feed inlet 13 is blocked and sealed again, thereby providing a closed environment for the material reaction. The closed environment is also conducive to further improving the heat preservation effect of the material.

[0068] Optionally, the cover plate 16 can be opened by means of rotational connection, snap-fit ​​connection, magnetic connection, etc. with the vessel body 1.

[0069] In one specific embodiment, please refer to Figure 3 The stirring device 5 may include a rotary motor 51, a stirring shaft 52, and multiple stirring blades 53.

[0070] A rotary motor 51 is located on the top of the cover plate 16, and a stirring shaft 52 is located on the bottom of the cover plate 16. One end of the stirring shaft 52 passes through the cover plate 16 and is connected to the rotary motor 51. The other end of the stirring shaft 52 is connected to multiple stirring blades 53. The multiple stirring blades 53 are arranged at intervals along the circumference of the stirring shaft 52.

[0071] In this embodiment, the stirring shaft 52 can be driven to rotate by the rotary motor 51, and the stirring shaft 52 in turn drives the stirring blades 53 on it to rotate, thereby achieving stirring of the material through the stirring blades 53. During use, since the rotary motor 51 is located on the top of the cover plate 16, the rotary motor 51 will not enter the inner cavity 11, will not cause contamination to the material, and can also effectively protect the rotary motor 51.

[0072] In one specific embodiment, a funnel 31 with its opening facing upwards is provided at the end of the liquid inlet pipe 3 away from the vessel body 1. The funnel 31 can increase the cross-sectional area of ​​the liquid inlet, thereby facilitating the manual addition of the insulation liquid by the operator and effectively reducing the risk of the insulation liquid spilling out. This is especially important when the insulation liquid is oil, as spilling oil will be detrimental to maintaining a clean and tidy production environment.

[0073] In some cases, the end of the inlet pipe 3 away from the vessel body 1 can also be connected to an external insulation liquid conveying device. The insulation liquid conveying device can pump the insulation liquid into the insulation chamber 12 through the inlet pipe 3 to realize the automated input of the insulation liquid and further improve the automation level of the device.

[0074] In one specific embodiment, a support rod 17 is also provided at the bottom of the vessel body 1. A support plate 18 is connected to the end of the support rod 17 away from the vessel body 1. A screw hole 181 is provided on the support plate 18. In practical applications, a bolt passing through the screw hole 181 on the support plate 18 from top to bottom is provided. The bolt can be fixedly connected to an external mounting base (not shown in the figure) to achieve the fixation of the vessel body 1.

[0075] In this embodiment, by elevating the vessel body 1 with the support rod 17, direct contact between the vessel body 1 and the ground can be avoided, thereby limiting the rapid heat loss of the vessel body 1 through the contact points and improving the heat preservation performance. In addition, elevating the vessel body 1 with the support rod 17 also makes it easier for operators to operate the discharge valve 2 and liquid discharge valve 4 at the bottom of the vessel body 1, making the structure more user-friendly and easier to use.

[0076] Preferably, the support rod 17 can be configured as a telescopic support rod, thereby enabling flexible adjustment of the height of the vessel body 1 above the ground based on the telescopic movement of the support rod 17. The structure of the telescopic support rod 17 can refer to the prior art, and this embodiment does not specifically limit it.

[0077] Further, please refer to Figure 4The reactor provided in this embodiment may further include a stepped support 19, which is disposed on the side of the reactor body 1 for operators to stand on, thereby facilitating the addition of materials to the elevated reactor body 1. Furthermore, the top of the stepped support 19 is fixedly connected to the reactor body 1, thus ensuring good stability of the stepped support 19 and preventing relative sliding between the stepped support 19 and the reactor body 1, which could lead to slips and injuries to the operators. A specific structure of the stepped support 19 can be found in [reference needed]. Figure 4 .

[0078] In summary, the reaction vessel provided by this utility model, by forming a heat-insulating cavity 12 between the inner and outer walls of the vessel body 1 and surrounding the outer perimeter of the inner cavity 11, and by realizing the entry and exit of the heat-insulating liquid through the liquid inlet pipe 3 and the liquid outlet valve 4, can reduce the heat loss of the material in the inner cavity 11 and play a preliminary heat-insulating role. The stirring device 5 can make the material in the inner cavity 11 uniformly mixed, avoiding local excessively high or low temperatures, and helping the material to be closer to the optimal temperature required for the reaction as a whole, improving the uniformity and stability of the reaction, thereby improving the reaction efficiency and product quality to a certain extent. The first electric heating device 6 heats the material in the inner cavity 11 to a first preset temperature, and the second electric heating device 7 heats the heat-insulating liquid to a second preset temperature higher than the first preset temperature. The setting of the dual electric heating devices can create a temperature difference between the material and the heat-insulating liquid, so that heat is transferred from the heat-insulating liquid to the material, compensating for the heat loss of the material due to heat dissipation, maintaining the material within the temperature range required for the reaction, improving the reaction efficiency of the material, and thus improving the quality and yield of the product.
