Description

Technical Field

[0001] The invention relates to the technical field of high temperature resistant reaction equipment, in particular to a high temperature resistant reaction device. Background Art

[0002] In the fields of chemistry, materials science, and industrial processing, reactors in high-temperature and high-pressure environments are core equipment, and their performance stability and safety are crucial to the entire production process. With the rapid development of science and technology, especially in the study of chemical reactions under extreme conditions, the application of high-temperature reaction devices is becoming more and more widespread. However, the pressure control mechanism of traditional high-temperature reaction devices is particularly insufficient when dealing with a sharp increase in internal pressure.

[0003] Traditional equipment mostly relies on simple pressure relief valves or bursting discs as passive pressure relief means. This type of method has significant limitations: on the one hand, its reaction is delayed, and it is difficult to respond quickly when the pressure reaches the dangerous threshold; on the other hand, the pressure relief process lacks precise control, which may lead to waste of resources due to too fast pressure relief, and may also cause safety hazards due to untimely pressure relief. In addition, frequent pressure relief operations may also increase the wear of the sealing structure of the reactor and reduce the service life of the equipment. What is more complicated is that under high temperature and high pressure environments, a large amount of gas, steam and incompletely reacted solid substances are often generated inside the reactor. If these by-products are not handled in a timely and effective manner, the instability of the pressure in the reactor will be further aggravated, increasing the risk of serious accidents such as explosions. To this end, the present invention proposes a high temperature resistant reaction device. Summary of the invention

[0004] The object of the present invention is to provide a high temperature resistant reaction device to solve the problem in the above background technology that the existing high temperature resistant reaction device cannot release pressure quickly.

[0005] To achieve the above object, the present invention provides the following technical solution: a high temperature resistant reaction device, comprising:

[0006] A stirring reaction mechanism, which includes a reaction kettle, a heat-insulating layer, an inlet, a stirring component and a driving component;

[0007] The insulation layer is sleeved on the outside of the reactor and is used to prevent the temperature in the reactor from being lost. The inlet is installed on the reactor and is used to add objects that need to be reacted into the reactor. The stirring component is used to stir the solvent in the reactor evenly. The driving component is used to drive the stirring component.

[0015] An air duct is provided on one side of the pressure relief chamber. When high-pressure gas is ejected from the pressure relief chamber, the gas is blown toward the fan blades through the air duct to rotate the fan blades. The sleeve and the cleaning rod rotate synchronously driven by the fan blades, thereby cleaning the crystals on the inner wall of the reactor.

[0016] Furthermore, a supporting foot is provided at the bottom of the thermal insulation layer, and a drain valve and a water inlet valve which penetrate the thermal insulation layer and are connected to the reactor are also provided on the thermal insulation layer.

The comparison strategy is used to obtain pressure information, compare it with a first pressure threshold or a second pressure threshold and generate control information, and transmit the control information to the control module to control the motor and the hydraulic pump.

[0020] Furthermore, the specific steps of controlling the motor based on the comparison strategy include:

[0021] If the comparison strategy detects that the pressure in the reactor is higher than the first pressure threshold, a shutdown command is generated to control the motor to stop rotating to prevent the solvent from fully reacting due to stirring and causing the pressure in the reactor to increase;

[0022] If the comparison strategy detects that the air pressure in the reactor is lower than the second pressure threshold, a power-on command is generated to control the motor to start rotating and re-stir the solvent inside the reactor to accelerate the reaction.

[0023] Furthermore, the specific steps of controlling the hydraulic pump based on the comparison strategy include:

[0025] If the comparison strategy detects that the air pressure in the reactor is lower than the second pressure threshold, a pressure increase instruction is generated to control the hydraulic pump to increase the pressure on the cover through the abutment rod to reduce the outflow of gas from the reactor.

[0026] Compared with the prior art, the present invention has the following significant effects:

[0027] 1. This high temperature resistant reaction device realizes efficient stirring of the solvent in the reactor through the stirring reaction mechanism. The stirring assembly adopts the first connecting shaft, the second connecting shaft and the array-distributed stirring paddles, combined with the planetary gear transmission system, so that the stirring paddles perform multi-dimensional stirring movements in the reactor, thereby ensuring the full mixing and uniform reaction of the solvent. This not only improves the reaction efficiency, but also ensures the quality stability of the reaction product.

[0028] 2. This high temperature resistant reaction device is equipped with a pressure relief cleaning mechanism and combined with an intelligent control system to achieve real-time monitoring and intelligent regulation of the air pressure in the reactor. When the air pressure exceeds the preset safety threshold, the valve assembly automatically opens and quickly releases excess gas through the pressure relief chamber, effectively preventing equipment damage or safety accidents caused by overpressure. At the same time, the design of the resistance assembly ensures that the valve is opened only when the specified air pressure value is reached, increasing the reliability of the system. In addition, the hydraulic pump can adjust the pressure on the cover according to the air pressure conditions, further enhancing the accuracy and flexibility of the pressure relief control.

[0029] 3. This high temperature resistant reaction device integrates a cleaning component and mechanically links it with a pressure relief component. It uses high pressure gas to blow the fan blades to rotate, which in turn drives the cleaning rod and cleaning brush to scrape and clean the inner wall of the reactor. This design greatly simplifies the post-reaction cleaning work, reduces manual intervention, and improves maintenance efficiency. At the same time, the cleaning component is cleverly combined with the structural design of the stirring reaction mechanism, so that the internal cleaning can be achieved without disassembling the reactor, reducing maintenance costs and extending the service life of the equipment.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] Embodiment 1:

[0041] See also Figure 1-Figure 8 This embodiment provides a high temperature resistant reaction device, comprising:

[0042] The stirring reaction mechanism 100 comprises a reaction vessel 101, a heat-insulating layer 102, an inlet 104, a stirring component and a driving component;

[0043] The heat-insulating layer 102 is sleeved on the outside of the reactor 101 and is used to prevent the temperature in the reactor 101 from being lost. The inlet 104 is installed on the reactor 101 and is used to add objects to be reacted into the reactor 101. The stirring component is used to stir the solvent in the reactor 101 evenly. The driving component is used to drive the stirring component.

[0044] The pressure relief cleaning mechanism 200 includes a pressure relief chamber 202, an air inlet pipe 2023, a valve assembly, a resistance assembly and a cleaning assembly;

[0045] The air inlet pipe 2023 is installed on the pressure relief chamber 202 and is used to connect the reactor 101 and the pressure relief chamber 202. The valve assembly is used to relieve pressure when the gas pressure in the reactor 101 is too high. The resistance assembly is used to apply resistance to the valve assembly so that it opens when the gas pressure in the reactor 101 reaches a specified value. The cleaning assembly is used to scrape and clean the crystals on the inner wall of the reactor 101.

[0046] The stirring reaction mechanism 100 accommodates the solvent or object to be reacted through the reactor 101, and the insulation layer 102 effectively prevents the temperature loss in the reactor 101, ensuring that the reaction is carried out under constant temperature conditions. The inlet 104 is used to add the object to be reacted into the reactor 101, and the stirring component, driven by the driving component, fully stirs the solvent or object in the reactor 101 to ensure that the reaction can be fully carried out. At the same time, the pressure relief cleaning mechanism 200 connects the reactor 101 with the pressure relief chamber 202 through the air inlet pipe 2023. The valve component remains closed under normal circumstances, but when the gas pressure in the reactor 101 is too large, it will overcome the resistance of the resistance component and open to release the overpressure gas to protect the reactor 101 from damage. In addition, the cleaning component can scrape and clean the inner wall of the reactor 101 when necessary, remove crystals or other impurities that may be attached to the inner wall, and ensure the cleaning of the reactor 101 and the normal progress of subsequent reactions.

[0047] The stirring assembly includes a first connecting shaft 1052 rotatably disposed in the reaction kettle 101 , a stirring plate 1051 is sleeved on the first connecting shaft 1052 , a second connecting shaft 1053 is rotatably disposed on the stirring plate 1051 , and stirring paddles 1054 are arrayed on the first connecting shaft 1052 and the second connecting shaft 1053 .

[0048] The stirring assembly drives the first connecting shaft 1052 to rotate through the motor 105, thereby driving the stirring plate 1051 to rotate. The second connecting shaft 1053 on the stirring plate 1051 is meshed with the planetary gear 1062 and the sun gear 1061 to achieve planetary motion around the axis of the first connecting shaft 1052. The stirring paddles 1054 arranged in an array on the first connecting shaft 1052 and the second connecting shaft 1053 continuously stir the solvent or object in the reactor 101 during the rotation process to ensure that the reactants are evenly mixed.

[0049] The driving assembly includes a motor 105, the output end of which is transmission-connected to a first connecting shaft 1052. An inner gear ring 106 and a planetary gear 1062 are provided in the reactor 101. The other end of the first connecting shaft 1052 extends to the outside of the stirring plate 1051 and the end is connected to a sun gear 1061 at the axis of the inner gear ring 106. A planetary gear 1062 is further provided between the inner gear ring 106 and the sun gear 1061. The planetary gear 1062 is connected to a second connecting shaft 1053, and the planetary gear 1062 moves in a planetary motion along the axis of the sun gear 1061.

[0050] The core of the driving assembly is the motor 105, whose output end is connected to the first connecting shaft 1052 to provide rotational power. The planetary gear 1062, the sun gear 1061 and the inner gear ring 106 in the reactor 101 constitute a planetary transmission mechanism, which transmits the rotational motion of the motor 105 to the second connecting shaft 1053, so that it performs planetary motion around the axis of the first connecting shaft 1052, thereby enhancing the stirring effect.

[0051] The valve assembly includes an exhaust joint 2021 arranged in a pressure relief chamber 202, the exhaust joint 2021 is sealed and connected to an intake pipe 2023 via a sealing ring, a pressure relief member 203 is arranged in the exhaust joint 2021, the pressure relief member 203 includes a rotating shaft rotatably arranged in the exhaust joint 2021, a valve plate 2031 is hinged on the rotating shaft, a spring 2032 for resetting the valve plate 2031 is arranged on the valve plate 2031, an X-shaped hinged rod 2033 is hinged on the valve plate 2031, and the other end of the X-shaped hinged rod 2033 is provided with a slide groove plate 2034 for limiting the sliding of the X-shaped hinged rod 2033.

[0052] The exhaust joint 2021 of the valve assembly is sealed and connected to the air inlet pipe 2023, and a pressure relief member 203 is provided inside. The valve plate 2031 of the pressure relief member 203 is kept in a closed state under the action of the spring 2032. When the gas pressure in the reactor 101 is too high, the gas pressure pushes the valve plate 2031 to overcome the elastic force of the spring 2032 to open and achieve pressure relief. The X-shaped hinge rod 2033 and the slide plate 2034 are used to limit the movement trajectory of the valve plate 2031 to ensure its stable opening and closing.

[0053] The resistance assembly includes an abutment rod 2042 arranged in the pressure relief chamber 202, and a mounting plate 2041 is sleeved on the outer wall of the abutment rod 2042, and the mounting plate 2041 is connected to the pressure relief chamber 202. The two ends of the abutment rod 2042 are respectively provided with a hydraulic pump 204 and a cover body 2022, and the inner wall of the cover body 2022 is connected to the slide plate 2034. Under normal conditions, the cover body 2022 is tightly fitted with the exhaust joint 2021 to form a sealed space for the exhaust joint 2021.

[0054] The two ends of the abutment rod 2042 of the resistance assembly are respectively connected to the hydraulic pump 204 and the cover 2022. Under normal conditions, the cover 2022 and the exhaust joint 2021 are tightly fitted to form a sealed space. When the gas pressure in the reactor 101 reaches the set value, the hydraulic pump 204 provides sufficient resistance, so that the cover 2022 moves under the action of the gas pressure and opens the exhaust joint 2021 to achieve pressure relief. This design ensures that the pressure relief operation is performed only when the gas pressure is too high.

[0055] The cleaning assembly comprises a sleeve 201 rotatably sleeved on the outer wall of the first connecting shaft 1052, a fan blade 2011 is provided in an annular array on the outer wall of the sleeve 201, a cleaning rod 2012 is also provided on the outer wall of the sleeve 201, and a cleaning brush is also provided on the cleaning rod 2012;

[0056] The sleeve 201 of the cleaning assembly is rotatably sleeved on the outer wall of the first connecting shaft 1052, and a fan blade 2011 and a cleaning rod 2012 are provided in a circular array on the outer wall. When the high-pressure gas is ejected from the pressure relief chamber 202, it is blown toward the fan blade 2011 through the air guide pipe and causes it to rotate. The sleeve 201 and the cleaning rod 2012 rotate synchronously under the drive of the fan blade 2011, and the cleaning brush on the cleaning rod 2012 scrapes and cleans the inner wall of the reactor 101 to remove attached crystals or other impurities.

[0057] An air duct is provided on one side of the pressure relief chamber 202. When high-pressure gas is ejected from the pressure relief chamber 202, the gas is blown toward the fan blades 2011 through the air duct, causing the fan blades 2011 to rotate. The sleeve 201 and the cleaning rod 2012 rotate synchronously under the drive of the fan blades 2011, thereby cleaning the crystals on the inner wall of the reactor 101.

[0058] A supporting foot 103 is disposed at the bottom of the thermal insulation layer 102 . A drain valve and a water inlet valve that penetrate the thermal insulation layer 102 and are connected to the reactor 101 are also disposed on the thermal insulation layer 102 .

[0059] The bottom of the insulation layer 102 is provided with a support foot 103 for supporting the entire device. The insulation layer 102 is also provided with a drain valve and a water inlet valve that penetrate and connect the reactor 101. The drain valve is used to discharge the liquid or cleaning water in the reactor 101, and the water inlet valve is used to add new solvent or cleaning water to the reactor 101. This design facilitates the cleaning and material replacement operations of the reactor 101. At the same time, the insulation layer 102 effectively prevents the loss of temperature in the reactor 101, ensuring that the reaction is carried out at a constant temperature.

[0060] As can be seen from the above, first, the stirring reaction mechanism 100 is started, and the motor 105 drives the first connecting shaft 1052 to rotate through the transmission connection, thereby driving the stirring plate 1051 and the second connecting shaft 1053 thereon to rotate. Due to the meshing action of the planetary gear 1062, the sun gear 1061 and the inner gear ring 106, the second connecting shaft 1053 not only rotates with the first connecting shaft 1052, but also performs planetary motion around its axis. This composite motion enables the stirring paddle 1054 to stir the solvent or object in the reactor 101 comprehensively and evenly, and the stirring paddle 1054 set on the first connecting shaft 1052 and the two second connecting shafts 1053 is used to realize the approximate control of the direction of the water flow inside the reactor 101. Due to the setting of the first connecting shaft 1052 and its own stirring paddle 1054, the water flow at the center of the reactor 101 is spirally clockwise as a whole, but the two second connecting shafts 1053 are rotating while revolving clockwise around the first connecting shaft 1052, which destroys the clockwise large circulation of the water flow at the center of the reactor 101 and generates turbulence at the stirring point of the two, effectively eliminating the generation of laminar flow to ensure that the reaction is fully carried out. At the same time, the insulation layer 102 effectively isolates the influence of the external temperature and maintains the constant temperature condition in the reactor 101. During the reaction process, if the gas pressure in the reactor 101 gradually increases and reaches the set value, the valve assembly starts to work. The high-pressure gas pushes the valve plate 2031 to overcome the elastic force of the spring 2032 and open, while the X-shaped hinged rod 2033 and the slide plate 2034 ensure that the valve plate 2031 is stably opened to achieve pressure relief. At this time, the hydraulic pump 204 in the resistance assembly provides appropriate resistance to ensure that the pressure relief operation is performed only when the pressure is indeed too high, thereby protecting the safety of the reactor 101. After the reaction is completed or when cleaning is required, the cleaning assembly comes into play. The high-pressure gas is ejected from the pressure relief chamber 202 and blows the fan blade 2011 to rotate through the air duct. The rotation of the fan blade 2011 drives the sleeve 201 and the cleaning rod 2012 thereon to rotate synchronously, and the cleaning brush on the cleaning rod 2012 scrapes and cleans the inner wall of the reactor 101 to remove attached crystals or other impurities. In addition, the drain valve and the water inlet valve on the insulation layer 102 are used to control the cleaning and refueling process of the reactor 101. The old liquid is discharged by opening the drain valve, and new solvent or cleaning water is added through the water inlet valve, and the cleaning components work in coordination to ensure the cleaning of the reactor 101 and the normal progress of subsequent reactions.

[0061] Embodiment 2:

[0062] Based on Example 1, please refer to Figure 1-Figure 8 :

[0063] The core drive motor is activated, and the main shaft (original first connecting shaft 1052) starts to rotate through the transmission chain. The main shaft drives the stirring plate (original stirring plate 1051) to rotate. At the same time, the planetary gear set (original planetary gear 1062 and sun gear 1061) interacts with each other, so that the secondary shaft (original second connecting shaft 1053) moves along the planetary trajectory to achieve a multi-dimensional stirring effect. The stirring paddle 1054 follows the movement trajectory of the main shaft and the secondary shaft to fully and evenly mix the reactants in the reactor 101 and promote the full reaction. The insulation layer 102 tightly wraps the reactor 101 to form a heat insulation barrier to ensure that the reaction is carried out at a constant temperature. The built-in pressure sensor monitors the pressure changes in the reactor 101 in real time. The safety valve (original valve plate 2031 and exhaust joint 2021 combination) remains closed under the action of the spring 2032 to form a sealed cavity. When the pressure exceeds the preset safety threshold, the safety valve automatically opens under the pressure to release excess gas to prevent damage to the equipment. The hydraulic damper (formerly the hydraulic pump 204) provides adjustable resistance, slows down the opening speed of the safety valve, and ensures a smooth pressure release. After the reaction is completed, the self-cleaning program is started through the control panel. High-pressure gas is introduced through the air guide device, blowing the turbine blades (formerly the blades 2011) to rotate at high speed. The rotation of the turbine blades drives the cleaning arm (formerly the cleaning rod 2012) to rotate around the main axis through the transmission mechanism, and the bristles on the cleaning arm scrape and clean the inner wall of the reactor 101. After cleaning, clean water can be introduced through the water inlet valve to rinse the reactor 101, and then the sewage can be discharged through the drain valve. Finally, the inside of the reactor 101 is dried with hot air, ready for the next use.

[0064] After the device is started, the core drive motor of the mixing and stirring module is activated, and the main shaft is driven to rotate through the transmission chain, thereby driving the stirring disk to rotate. At the same time, the planetary gear set interacts with each other to make the secondary shaft move along the planetary trajectory, achieving a multi-dimensional stirring effect, ensuring that the reactants in the reactor 101 are fully and evenly mixed, and promoting the full reaction. In this process, the insulation layer 102 tightly wraps the reactor 101 to maintain the constant temperature required for the reaction. As the reaction proceeds, the pressure sensor built into the pressure control module monitors the pressure changes in the reactor 101 in real time. When the pressure exceeds the preset safety threshold, the safety valve automatically opens under the pressure to release excess gas to the preset pressure relief chamber 202. The hydraulic damper provides adjustable resistance to ensure that the pressure release is smooth and protect the equipment from overpressure damage. After the reaction is completed, the self-cleaning maintenance module is started through the control panel. High-pressure gas is introduced through the air guide device, blowing the turbine blades to rotate at high speed. The rotation of the turbine blades drives the cleaning arm to rotate around the main shaft through the transmission mechanism, and the bristles on the cleaning arm scrape and clean the inner wall of the reactor 101 to remove attached residues. After cleaning, clean water can be introduced through the water inlet valve to rinse the reactor 101, and then the sewage can be discharged through the drain valve. Finally, the hot air system can be used to dry the inside of the reactor 101 to prepare for the next use.

[0065] Embodiment three:

[0066] Based on the first and second embodiments, please refer to Figure 1-Figure 8 , further comprising a processor, the processor being equipped with a control system for controlling pressure relief according to the air pressure in the reactor 101, the control system being equipped with a sensor module, a data processing module and a control module;

[0067] The sensor module includes a pressure unit, which is used to obtain the magnitude of the air pressure in the reactor 101 and generate pressure information;

[0068] The data processing module includes a pressure unit, which is equipped with a comparison strategy and a pressure strategy. The comparison strategy is used to obtain pressure information, compare it with the first pressure threshold or the second pressure threshold and generate control information, which is transmitted to the control module to control the motor 105 and the hydraulic pump 204 based on the control information.

[0069] The specific steps of controlling the motor 105 based on the comparison strategy include:

[0070] If the comparison strategy detects that the pressure in the reactor 101 is higher than the first pressure threshold, a shutdown command is generated to control the motor 105 to stop rotating, so as to prevent the solvent from fully reacting due to stirring and causing the pressure in the reactor 101 to increase;

[0071] If the comparison strategy detects that the air pressure in the reactor 101 is lower than the second pressure threshold, a start-up instruction is generated to control the motor 105 to start rotating, so as to re-stir the solvent in the reactor 101 to accelerate the reaction.

[0072] The specific steps of controlling the hydraulic pump 204 based on the comparison strategy include:

[0073] If the comparison strategy detects that the air pressure in the reactor 101 is higher than the first pressure threshold, a decompression instruction is generated to control the hydraulic pump 204 to reduce the pressure on the cover 2022 through the abutment rod 2042 to accelerate the outflow of the gas inside the reactor 101;

[0074] If the comparison strategy detects that the air pressure in the reactor 101 is lower than the second pressure threshold, a pressure increase instruction is generated to control the hydraulic pump 204 to increase the pressure on the cover 2022 through the abutment rod 2042 to reduce the outflow of gas from the reactor 101.

[0075] From the above, we can see that:

[0076] After the system is started, each module enters the standby state, and the sensor module begins to obtain the air pressure information in the reactor 101 in real time and transmits it to the data processing module. Subsequently, according to the preset conditions or user instructions, the control module generates a power-on instruction through the data processing module, and starts the motor 105 for stirring reaction. During the stirring process, the sensor module continuously monitors the air pressure changes, and the data processing module compares the real-time pressure with the first and second pressure thresholds according to the comparison strategy. If the air pressure is higher than the first pressure threshold, a shutdown instruction is generated to stop the motor 105 from rotating to prevent the pressure from increasing; if the air pressure is lower than the second pressure threshold, a power-on instruction is generated to restart the motor 105 for stirring. If the air pressure continues to be higher than the first pressure threshold and reaches a dangerous level, the data processing module will generate a decompression instruction, and the control module will adjust the hydraulic pump 204 to reduce the pressure of the cover 2022, accelerate the gas outflow and achieve safe pressure relief. If a specific pressure needs to be maintained and the air pressure is too low, although it is not common, the pressure of the hydraulic pump 204 can be adjusted through the boost instruction. After the reaction is finished, the automatic cleaning program is started, and the fan blade 2011 is blown by high-pressure gas to drive the cleaning rod 2012 to clean the inner wall of the reactor 101, followed by rinsing and drying. Regularly check and replace wearing parts to ensure stable operation of the device. Finally, after completing all operations, turn off the system power supply, and each module enters a dormant state and waits for the next startup.
