Description

Technical Field

[0001] This invention relates to the field of chemical technology, and more specifically, to an apparatus for synthesizing a cyclohexane intermediate. Background Technology

[0002] Cyazofamid is a novel, low-toxicity fungicide, mainly used to control oomycete diseases such as downy mildew, downy mildew, and late blight. It is suitable for crops such as potatoes, tomatoes, peppers, and cucumbers, and as an important fungicide, it has a wide range of applications in the agricultural field.

[0003] A search revealed that Chinese patent CN214106883U discloses a synthesis device for a cyclohexane intermediate, including a main processor. The main processor has a sealing cover on its top, a first connecting hole inside the sealing cover, a handle on the outer wall of the first connecting hole, a mounting base on the side of the support column away from the support block, and a first mounting block on the side of the mounting base close to the support column. The first mounting block has an movable hole inside.

[0004] The aforementioned patents still have shortcomings in practical use. The cyclization synthesis equipment requires a high-temperature and high-pressure environment, and since pressure is related to temperature, the equipment needs to heat the reactor during use. At the same time, the reactor needs to react for a period of time to meet the pressure requirements, which greatly affects the reaction efficiency. Secondly, during the gradual reaction process in the reactor, chloride gas is generated, which increases the pressure. Therefore, it is necessary to release some gas to reduce the pressure. However, the internal reaction temperature also needs to be controlled. Existing equipment often reduces pressure and temperature by releasing gas, which leads to waste of raw materials and low concentration of cyclization compounds.

[0005] Based on this, the present invention discloses a device for synthesizing cyclohexane intermediates of cypermethrin. Summary of the Invention

[0006] To solve the problems raised in the background art, the object of the present invention is to provide a synthesis device for cyazofamid intermediate cyclic compound, which, through the cooperation of a hydraulic lifting device and a piston disk, after raw materials are added into the reaction kettle, the hydraulic lifting device drives the piston disk to descend, rapidly increasing the pressure in the reaction kettle to a predetermined value; secondly, combined with the linkage design of a heat engine component and a first control component, as the piston disk descends, the first control component automatically activates the heat engine component, delivering the heated heat-conducting liquid into the sleeve, enabling the temperature of the reaction kettle to quickly reach the set value; then, with the intelligent switching mechanism of a cold machine component and a second control component, when the gas generated during the reaction causes the pressure to exceed the preset value, the piston disk rises to reduce the pressure, and triggers the intervention of the cold machine component, regulating the temperature in the reaction kettle by circulating the cooling liquid; finally, in cooperation with an electromagnetic strip and a rack, the linkage operation between control components is achieved by combining the electromagnetic strip and the mechanical rack, ensuring the automation degree throughout the entire process from pressurization to temperature reduction and pressure reduction.

A first guide rail is fixedly connected to the inner wall of the first mounting box on the side opposite to the first electromagnetic bar. A second of the first electromagnetic bars is slidably connected to the first guide rail.

[0015] Preferably, a first electromagnetic switch is disposed in the first groove directly below the bottom end of the first rack; and the first rack will not trigger the first electromagnetic switch under its own weight.

[0016] In the initial state, the first rack is located at the top of the first mounting box, and the second of the first electromagnetic bars is in a repulsive state with the first of the first electromagnetic bars.

[0017] As a further improvement to this technical solution, the first control switch includes a mounting ring, which is fixedly connected to the first mounting box.

A second transmission rod is rotatably connected inside the second mounting box. A second transmission gear is fixedly connected to the second transmission rod. A second rack and a second reduction gear are symmetrically meshed on both sides of the second transmission gear. The second reduction gear is fixedly connected to a second connecting rod.

[0025] As a further improvement to this technical solution, the pressure value of the pressure valve is adapted to the pressure threshold of the reaction of the cyclic compound in the reactor; and the absorption device is equipped with a substance for absorbing the chemical gas discharged from the pressure valve.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. In this equipment for synthesizing a cyclohexane intermediate, a hydraulic lifting device works in conjunction with a piston disc. The hydraulic lifting device moves the piston disc up and down, rapidly adjusting the pressure inside the reactor. This real-time pressure adjustment avoids the inefficient process of traditional reactors where raw materials react for extended periods to reach the predetermined pressure, thus improving reaction efficiency. Secondly, the piston disc's descent triggers the heating of the thermal engine component. When the piston disc descends, the first control component activates the thermal engine component, rapidly heating the sleeve with the heated heat transfer fluid to increase the reactor temperature. This quickly brings the reactor temperature to the predetermined value, accelerating the reaction process. Furthermore, the piston disc's ascent automatically activates the cooling component. When the pressure inside the reactor exceeds the predetermined value, the piston disc rises, and the second control component activates the cooling component, delivering the cooled heat transfer fluid to the sleeve to cool the reactor. This process ensures that the temperature and pressure remain within the ideal range during the reaction, preventing overheating and equipment damage, effectively guaranteeing equipment safety and improving reaction stability.

[0028] 2. In this equipment for synthesizing a cyclohexane intermediate, the first and second control components are linked by an electromagnetic strip, a rack and pinion, and a control switch. Simultaneously, the lifting and lowering of the piston disc is used to adjust the switching of the heating and cooling components, thereby improving the accuracy of temperature and pressure control. This ensures that the reaction temperature and pressure are always at their optimal levels, avoiding reaction failure or raw material waste due to improper temperature and pressure control. Furthermore, by setting the heating and cooling components to work alternately, the equipment can adjust heating or cooling according to the real-time temperature and pressure inside the reactor. This control method makes the reaction process more efficient and energy-saving, and avoids the excessive energy and raw material waste often found in traditional methods.

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This invention provides an apparatus for synthesizing cyclohexane intermediates of cypermethrin, see [link to apparatus]. Figures 1-2 As shown, it includes a protective shell 1, a reaction vessel 2 is disposed inside the protective shell 1, and a pressure gauge 13 is disposed on the protective shell 1, with the probe end of the pressure gauge 13 located inside the reaction vessel 2.

[0050] Specifically, a piston disc 7 is slidably mounted on the top of the reactor 2, and a hydraulic lifting device 6 is mounted on the top of the protective shell 1. The bottom end of the hydraulic lifting device 6 is fixedly connected to the piston disc 7. A sleeve 3 for heating or cooling the reactor 2 is fitted around its periphery. A cooling assembly 4 and a heating assembly 5 are respectively mounted on both sides of the protective shell 1. The cooling assembly 4 and the heating assembly 5 are respectively connected to the sleeve 3. A first control assembly 8 and a second control assembly 9 are symmetrically mounted inside the top of the protective shell 1. The first control assembly 8 and the second control assembly 9 respectively control the opening and closing of the heating assembly 5 and the cooling assembly 4. The lifting and lowering of the piston disc 7 is related to the pressure value of the pressure gauge 13. When the piston disc 7 descends, the first control assembly 8 controls the opening of the heating assembly 5. When the piston disc 7 rises, the second control assembly 9 controls the opening of the cooling assembly 4. A pressure valve 10 is mounted on the piston disc 7. An exhaust pipe 11 is connected to the top of the protective shell 1. The end of the exhaust pipe 11 away from the protective shell 1 is connected to an absorption device 12.

[0051] Therefore, when the reactants are added to the reactor 2, the hydraulic lifting device 6 lowers the piston plate 7 according to the predetermined pressure and temperature, so that the pressure inside the reactor 2 reaches the predetermined pressure value first. In contrast, the traditional reactor 2 requires the reactants to react for a period of time before reaching the predetermined pressure value, thus saving a lot of time and improving reaction efficiency. Secondly, during the descent of the hydraulic lifting device 6, the first control component 8 controls the opening of the heat engine component 5, which then delivers the heated heat transfer fluid to the sleeve 3. Since the sleeve 3 is fitted outside the reactor 2, it can continuously heat the reactor 2, allowing the temperature inside the reactor 2 to reach the predetermined temperature value. Through the above steps, the predetermined reaction temperature and pressure can be achieved in the reactor 2 efficiently, greatly improving reaction efficiency. Then, after the reaction begins, once the pressure exceeds the predetermined value, the excess gas inside the reactor 2 will be discharged through the pressure valve 10 and then enter the suction pipe 11. The absorption and utilization are carried out in the receiving device 12; at this time, it is equivalent to the start of a large-scale reaction in the reactor 2, that is, the temperature and pressure in the reactor 2 will continue to rise. At this time, in order to ensure the safety of the equipment and the stability of the reaction, it is necessary to control the pressure and temperature. The traditional method of simply releasing gas is slow and will cause a lot of waste of raw materials. Therefore, when gas is discharged through the pressure valve 10, in order to ensure the stability of the pressure, the piston plate 7 will slowly rise to reduce the pressure in the reactor 2 and reduce the gas discharge from the pressure valve 10. High pressure also means high temperature. When the piston plate 7 rises, it will drive the shutdown of the heat engine component 5, and then drive the start of the cooling component 4. Then, it will continuously transport the cooled heat transfer fluid in the sleeve 3 into the sleeve 3 to replace the original high-temperature heat transfer fluid. In this way, the temperature in the reactor 2 can be quickly controlled, so that the temperature and pressure of the reaction in the reactor 2 can be controlled efficiently, while reducing the waste of raw materials.

[0052] The specific structure of the present invention will be disclosed below. First, see [link to previous section]. Figure 2As shown, the heat engine assembly 5 includes a second water pump 51 and a heating assembly 52. ​​One end of the second water pump 51 is connected to a second connecting pipe 54, which connects the second water pump 51 to one end of the heating assembly 52. ​​The other end of the second water pump 51 is connected to a second water suction pipe 53, with the end of the second water suction pipe 53 away from the second water pump 51 connected to the top of one side of the sleeve 3. The other end of the heating assembly 52 is connected to a second water inlet pipe 55, with the end of the second water inlet pipe 55 away from the heating assembly 52 connected to the bottom of the sleeve 3 on the side away from the second water suction pipe 53. In other words, the first thing to be turned on is the heat engine component 5, which contains pre-stored heated heat transfer fluid. Then, the second water pump 51 starts, driving the circulation of the heat transfer fluid in the heating component 52 through the second connecting pipe 54. The fluid is then drawn into the sleeve 3 through the second inlet pipe 55, and finally drawn back into the second water pump 51 through the second outlet pipe 53, forming a circulation. The cooling component 4 described below follows the same process. Secondly, the cooling component 4 includes a first water pump 41 and a refrigeration unit 42. One end of the second water pump 51 is connected to the first connecting pipe 44, and the first water pump 41... One end of the first water pump 41 is connected to the first water pump 42, and the other end of the first water pump 41 is connected to the first water pump 43. The end of the first water pump 43 away from the first water pump 41 is connected to the top of one side of the sleeve 3. The other end of the first water pump 42 is connected to the first water inlet pipe 45. The end of the first water inlet pipe 45 away from the first water pump 42 is connected to the bottom of the sleeve 3 away from the first water pump 43. It is worth mentioning that both the first water pump 43 and the second water pump 53 are equipped with a one-way valve that only allows water to flow out of the sleeve 3, unlike the sleeve 3 which only allows water to flow in. The first water inlet pipe 45 and the first water pump 42 are connected to the first water pump 43, and the second water pump 53 are connected to the sleeve 3. The second water inlet pipe 55 is equipped with a one-way valve at the end connected to the sleeve 3, which allows only inflow and outflow compared to the sleeve 3. Simultaneously, corresponding circuit switching devices are installed in both the second water pump 51 and the first water pump 41. This means that the corresponding circuit is only connected when either the second water pump 51 or the first water pump 41 is turned on. This prevents the heat transfer fluid in the heating component 52 from being drawn into the sleeve 3 when the cooling component 4 starts, or the heat transfer fluid in the cooling device 42 from being drawn into the sleeve 3 when the heating component 5 starts. The first water inlet pipe 43 and the first water outlet pipe 45 are... Figure 2 The positions shown are designed so that they are on opposite sides and one is higher than the other, which facilitates the rapid filling of the entire sleeve 3 with heat transfer fluid and improves the circulation efficiency. The same applies to the second pumping pipe 53 and the second inlet pipe 55.

[0053] Further, see Figure 3As shown, the first control component 8 includes a first mounting box 81 fixed inside the top of the protective shell 1 and located on one side of the hydraulic lifting device 6. A first transmission rod 82 is rotatably connected inside the first mounting box 81. A first transmission gear 83 is fixedly connected to the first transmission rod 82. A first rack 88 and a first reduction gear 84 are symmetrically meshed on both sides of the first transmission gear 83. The first reduction gear 84 is fixedly connected to a first connecting rod 85. The first connecting rod 85 is rotatably connected inside the first mounting box 81. A first sliding groove 90 is provided on the piston disc 7. A first slot 89 adapted to the first sliding groove 90 is provided at the bottom of the first mounting box 81. The bottom end of the first rack 88 passes through the first slot 89 and is slidably connected inside the first sliding groove 90. A first torsion spring 87 is provided at one end of the first connecting rod 85. One end of the first torsion spring 87 is connected to the first mounting box 81. The inner wall of the packaging box 81 is fixedly connected, and the other end is fixedly connected to the first connecting rod 85. The end of the first connecting rod 85 away from the first torsion spring 87 is provided with a first control switch 86, which is used to control the switching of the heat engine assembly 5. In this way, when the piston disc 7 descends, it will drive the first rack 88 to descend, and then drive the first reduction gear 84 to rotate through the first transmission gear 83 meshing with the first rack 88. In turn, it will drive the first connecting rod 85 to rotate, thus controlling the switching of the first control switch 86. The specific control method is described below. That is to say, as long as the first connecting rod 85 rotates, the first control switch 86 will be opened, and then the heat engine assembly 5 will be started. This linkage can ensure that as long as the piston disc 7 is started, the sleeve 3 will be heated at the same time, ensuring that the pressure and temperature in the reactor 2 rise simultaneously.

[0054] See Figure 3 and Figure 5 As shown, a first electromagnetic bar 901 is fixedly provided on the side of the first rack 88 away from the first transmission gear 83, and a first guide rail 903 is fixedly connected on the inner wall of the first mounting box 81 opposite to the first electromagnetic bar 901. A second first electromagnetic bar 902 is slidably connected on the first guide rail 903.

[0055] Additionally, it should be noted that a first electromagnetic switch (not shown in the figure) is located directly below the bottom end of the first rack 88 within the first slide groove 90; and the first rack 88 will not trigger the first electromagnetic switch under its own weight; moreover, in the initial state, the first rack 88 is located at the top of the first mounting box 81, and the second electromagnetic bar 902 and the first electromagnetic bar 901 are in a repulsive state; thus, it can be seen that in the initial state, the second electromagnetic bar 902 is in the open state, and the magnetic repulsion between it and the first electromagnetic bar 901 ensures that the first rack 88 is always engaged with the first transmission gear 83. Therefore, when the piston disc 7 descends, the first transmission gear 83 can be rotated through the first rack 88. The reason for setting the first reduction gear 84 is to reduce the rotation angle of the first connecting rod 85. When the first rack 88 descends to the predetermined height, that is, when the pressure inside the reactor 2 reaches the predetermined value, the first rack 88 also stops descending. At this time, due to the meshing action of the first transmission gear 83 on the first rack 88, and the fact that the weight of the first rack 88 itself is insufficient to start the first electromagnetic switch, the second electromagnetic bar 902 and the first electromagnetic bar 901 are always in a repulsive state, ensuring the meshing of the first rack 88 with the first transmission gear 83. This ensures the stability of the first connecting rod 85, thereby ensuring that the first control switch 86 is always in the open state. Then, the heat engine assembly 5 will continuously supply heat to the sleeve 3.

[0056] For the first control switch 86, see [link / reference] Figure 4 As shown, the first control switch 86 includes a mounting ring 861, which is fixedly connected inside the first mounting box 81. An electrical ring 862 is fixed inside the mounting ring 861, and a notch is provided at the top of the electrical ring 862. In the initial state, an electrical rod 863 is provided directly below the notch, and the electrical rod 863 is fixedly connected to a fixing ring 864. The fixing ring 864 is fixedly connected to the first connecting rod 85.

[0057] from Figure 4It can also be seen that when the electric rod 863 rotates away from the notch, the top of the electric rod 863 is in contact with the inner wall of the electric ring 862, and the electric ring 862 is electrically connected to the electric rod 863. The second water pump 51 and the heating assembly 52 start when the electric ring 862 is in contact with the electric rod 863. It is also worth noting that the first torsion spring 87 always tends to keep the electric rod 863 directly below the notch. Thus, it can be concluded that initially, the electric rod 863 is below the notch, and at this time, the electric rod 863 is not in contact with the electric ring 862. Therefore, the electric rod 863 and the electric ring 862 are not electrically connected, and the heat engine assembly 5 will not be started. When the piston disc 7 descends according to the above steps, causing the first connecting rod 85 to rotate, the electric rod 863 will also rotate, causing the electric rod 863 to leave the notch and then form a circuit with the electric ring 862, resulting in the heat engine assembly 5 being opened. Combined with the above... It is known that as long as the first rack 88 meshes with the first transmission gear 83, the electrical ring 862 and the electrical rod 863 will be in the connected state. When the piston disc 7 is about to rise, that is, as mentioned above, it is necessary to depressurize the reactor 2. At this time, it is also necessary to cool the reactor 2 (because pressure and temperature are related). Therefore, the rise of the piston disc 7 causes the first electromagnetic switch in the first slide groove 90 to squeeze the first rack 88. At this time, the first electromagnetic switch will be triggered, and the second electromagnetic bar 902 will become magnetically attracted to the first electromagnetic bar 901, causing the first rack 88 to slide in the first slide groove 90 until it disengages from the first transmission gear 83. Then the first connecting rod 85 will be reset under the torque of the first torsion spring 87, thereby driving the electrical rod 863 to reset to the notch position and then disconnect from the electrical ring 862, thus shutting down the thermomechanical assembly 5.

[0058] Furthermore, see Figure 3 , Figure 4 and Figure 9 As shown, the second control component 9 includes a second mounting box 91 located on the other side of the hydraulic lifting device 6. A second transmission rod 92 is rotatably connected inside the second mounting box 91. A second transmission gear 93 is fixedly connected to the second transmission rod 92. A second rack 98 and a second reduction gear 94 are symmetrically meshed on both sides of the second transmission gear 93. The second reduction gear 94 is fixedly connected to the second connecting rod 95. The second connecting rod 95 is rotatably connected inside the second mounting box 91. A second slide groove 990 is also provided on the piston disc 7. A second slot 99 that matches the second slide groove 990 is provided at the bottom of the second mounting box 91. The bottom end of the second rack 98 passes through the second slot 99 and is slidably connected inside the second slide groove 990. A second torsion spring 97 is provided at one end of the second connecting rod 95. One end of the second torsion spring 97 is fixedly connected to the inner wall of the second mounting box 91, and the other end is fixedly connected to the second connecting rod 95. A second control switch 96 is provided at the end of the second connecting rod 95 away from the second torsion spring 97, which is used to control the switching of the refrigeration unit 4.

[0059] A second electromagnetic bar 991 is fixedly provided on the side of the second rack 98 away from the second transmission gear 93. A second guide rail 993 is fixedly connected on the inner wall of the second mounting box 91 on the side opposite to the second electromagnetic bar 991. A second electromagnetic bar 992 is slidably connected on the second guide rail 993.

[0060] A second electromagnetic switch 994 is fixed on the inner wall of the top of the second mounting box 91, directly above the second rack 98. Both the first electromagnetic switch and the second electromagnetic switch 994 are used to control the magnetic conversion of the second electromagnetic bar 902 and the second electromagnetic bar 992. In the initial state, the top of the second rack 98 is in contact with the second electromagnetic switch 994, but the second electromagnetic switch 994 is not triggered.

[0061] The second control switch 96 has the same structure as the first control switch 86. Initially, the first electromagnetic bar 991 and the second electromagnetic bar 992 are in an attractive state. As mentioned above, when the piston disc 7 begins to rise, the first electromagnetic switch is triggered. (See [link]). Figure 9 As shown, the initial attraction between the second electromagnetic bar 992 and the first electromagnetic bar 991 changes to a repulsive state. This causes the second rack 98 to slide within the second groove 990 until it meshes with the second transmission gear 93. If the piston disc 7 rises further, it will rotate the second connecting rod 95 according to the working principle of the first control component 8, causing the second control switch 96 to open, thereby activating the cooling component 4 to cool the sleeve 3. As the piston disc 7 gradually rises to reduce the pressure inside the reactor 2, after the reaction is complete, the piston disc 7 rises to the top, but needs to be slightly higher than the initial state, triggering the second electromagnetic switch 994. At this point, the first electromagnetic bar 901 and the first electromagnetic bar 992... The second electromagnetic bar 902 then repels the first gear 88, which meshes with the first transmission gear 83 to return to its initial state. Meanwhile, the second electromagnetic bar 991 and the second electromagnetic bar 992 attract each other, and the second electromagnetic bar 98 disengages from the second transmission gear 93 to return to its initial state. In this way, the height of the piston disc 7 can be adjusted efficiently according to the reaction in the reactor 2, so that the pressure in the reactor 2 can quickly reach the predetermined pressure. At the same time, with the intervention of the cooling component 4 and the heating component 5, the temperature in the reactor 2 can be adjusted in a timely manner, reducing the waste of raw materials caused by the traditional method of reducing pressure and temperature by venting reaction gases. Moreover, it avoids the inefficient operation that requires a long reaction time to reach the predetermined pressure in the early stage. This is both efficient and saves raw materials.

[0062] In addition, see Figure 3As shown, the second reduction gear 94 and the first reduction gear 84 have the same structure, and the second transmission gear 93 and the first transmission gear 83 have the same structure. The number of teeth on the first reduction gear 84 is greater than the number of teeth on the first transmission gear 83. Furthermore, when the piston disc 7 descends to its lowest point, the first reduction gear 84 rotates less than 360°, and when the piston disc 7 rises to its highest point, the second reduction gear 94 rotates less than 360°. This combination... Figure 4 It can be concluded that the electrical connection between the electric rod 863 and the electric ring 862 can be ensured before the piston disc 7 descends to the bottom. That is to say, the heat engine assembly 5 can be kept open during the descent of the piston disc 7. However, once it rises, the electric rod 863 will be reset to its initial state by the first torsion spring 87 (by controlling the disengagement of the first rack 88 and the first transmission gear 83 through the first electromagnetic switch, the first connecting rod 85 is reset under the torque of the first torsion spring 87, see the working principle below for details), so that the electric rod 863 and the electric ring 862 are in an open circuit state. The same principle applies to the second control switch 96 in the second control assembly 9. As long as the piston disc 7 starts to rise, the second control switch 96 is in the on state. When it gradually returns to the top, that is, the initial position of the piston disc 7, the second control switch 96 will be reset to its initial state.

[0063] In addition, the pressure value of pressure valve 10 is compatible with the pressure threshold of the reaction of the cyclic compound in reactor 2; and the absorption device 12 is equipped with substances that absorb the chemical gases discharged from pressure valve 10.

[0064] The specific working principle is as follows:

[0065] See Figures 5-8 As shown, first Figure 5 This represents the initial state of the first control component 8. At this time, the second electromagnetic bar 902 and the first electromagnetic bar 901 repel each other, the first rack 88 meshes with the first transmission gear 83, and the piston disc 7 has not yet begun to descend. Then, in the initial stage of the reaction, the piston disc 7 begins to descend to increase the pressure inside the reaction vessel 2, thereby achieving... Figure 6 As shown in the status, the piston disk 7 has reached the predetermined position, meaning the pressure inside the reactor 2 meets the requirements. However, once the reaction begins, as the pressure inside the reactor 2 rises, the piston disk 7 needs to rise to reduce the pressure. When the piston disk 7 rises, the first electromagnetic switch at the bottom of the first slide groove 90 is triggered by the piston disk 7 pressing against the first rack 88. This causes the second electromagnetic bar 902 and the first electromagnetic bar 901 to become magnetically attracted. At this point, as... Figure 7As shown, the first rack 88 will be attracted and slide within the first groove 90. Then, the first rack 88 will disengage from the first transmission gear 83. During the subsequent rise of the piston disc 7, the first rack 88, the first electromagnetic bar 901, and the second electromagnetic bar 902 will slide and rise along the first guide rail 903 until they reach the initial position. Then, triggered by the second electromagnetic switch 994 mentioned above, the second electromagnetic bar 902 and the first electromagnetic bar 901 will return to their repulsive state, and then return to the initial position. Figure 5 It is worth noting that the second electromagnetic bar 902, the first electromagnetic bar 901, the second electromagnetic bar 992, and the first electromagnetic bar 991 are all long strips, which can ensure that the magnetic force is applied over a wide area.

[0066] See next Figures 9-12 As shown, this illustrates the process of the second control component 9 moving from its initial state to its restored initial state. First, refer to... Figure 9 As shown, in the initial state, the second electromagnetic bar 992 and the second electromagnetic bar 991 are attracted to each other, and the second rack 98 and the second transmission gear 93 are not engaged. Then, under the drive of the piston disc 7, it moves downward to... Figure 10 In this state, the second control switch 96 will not be triggered. Then, when the piston disc 7 rises and the first electromagnetic switch is triggered, the magnetism of the second electromagnetic bar 992 and the second guide rail 993 is changed, becoming repulsive. At this time, the second rack 98 is pushed in the second slide groove 990 until it meshes with the second transmission gear 93, reaching the desired state. Figure 11 If the piston disc 7 continues to rise, it will cause the second connecting rod 95 to rotate, thereby triggering the second control switch 96. The cooling assembly 4 will then begin operation. Before the piston disc 7 reaches its initial state, the second rack 98 remains engaged with the second transmission gear 93, ensuring the cooling assembly 4 is always operational. Because the temperature and pressure continuously rise after the reaction, this process involves continuous pressure and temperature reduction. Therefore, the piston disc 7 needs to rise slowly and continuously, and the cooling assembly 4 will continue to operate until the reaction is complete and the piston disc 7 reaches a position slightly above its peak. Figure 12 As shown, this will trigger the second electromagnetic switch 994, and then the second electromagnetic bar 992 and the first electromagnetic bar 991 will become magnetically attracted again. The second rack 98 will be attracted back and disengaged from the second transmission gear 93. Then the second control switch 96 will return to its initial state, and the cooling unit 4 will shut down.
