Technical Field
[0001] This invention relates to the field of cooling device technology, specifically to a cooling device and method for chemical pharmaceuticals. Background Technology
[0002] Cooling devices are key equipment for temperature control in chemical and pharmaceutical production. They can effectively prevent materials from deteriorating or reactions from going out of control due to high temperatures. In the production of chemical drugs, precise cooling is of paramount importance. Jacketed cooling reactors have emerged to meet this need. They achieve efficient and uniform heat exchange by utilizing the flow of cooling medium between the reactor body and the jacket. They can precisely control the cooling rate, ensuring the safety of drug synthesis and the purity of the product, and have become the core equipment for cooling chemical drugs.
[0003] However, existing jacketed cooling reactors are prone to agitator shaft breakage due to aging and other issues. The breakage is not immediately apparent until the shaft is completely severed, inevitably causing serious damage to the reactor's inner wall. Furthermore, the lower half of the shaft lacks adequate support in the early stages of breakage, making it impossible to salvage the shaft and increasing the likelihood of complete failure. Moreover, the shaft cannot be quickly disassembled and replaced, often requiring considerable time and significantly extending the period of equipment downtime, drastically reducing processing efficiency.
[0004] In light of the above issues, it becomes clear that existing chemical drug cooling devices on the market cannot simultaneously avoid the problems mentioned above during use. Even if they can be solved, they require the assistance of external tools, thus failing to achieve the desired effect. Therefore, we propose a chemical drug cooling device and method.

[0014] Preferably, the inner wall of the rectangular plate and the inner wall of the jacketed cooling reactor body are connected by two sets of fixing bolts, each set of fixing bolts consists of two bolts, and the teeth of each fixing bolt mesh with the teeth of the sliding toothed plate. Two second stepper motors are fixedly connected to the upper surface of the jacketed cooling reactor body, and the output end of each second stepper motor is fixedly connected to one end of a third threaded shaft. Each second stepper motor is electrically connected to a delay button via a wire.
[0015] A method of using a cooling device for chemical pharmaceuticals includes the following steps: S1: When the equipment is in normal use, the stirring shaft body will rotate under the action of the first step motor, stirring the drugs inside the jacketed cooling reactor. As the stirring shaft body rotates, it will synchronously drive the lifting plate to rotate. It's important to understand that although the lifting plate is threadedly connected to the first threaded shaft, it is not subject to any structural restraints. Therefore, the lifting plate will rotate along with the first threaded shaft and the stirring shaft body. Additionally, the steel wire fixed to the inner wall of the stirring shaft body will also rotate synchronously. To prevent the steel wire from tightening itself, the rotating plate fixed to the top of the steel wire will rotate under the combined action of the first drive shaft and the first threaded shaft. Therefore, the steel wire can rotate along with the stirring shaft body, and the rotating plate is rotatably connected to the inner wall of the circular plate. Thus, the rotation of the rotating plate does not affect the state of the circular plate. When the stirring shaft body shows signs of breakage during use, it will slightly deform in the initial stage of the breakage. This slight deformation will pull the steel wire, causing it to move the rotating plate downwards. This, in turn, will cause the spring to stretch. As the rotating plate moves downwards, it will also cause the third transmission shaft to move downwards. It's important to understand that the third transmission shaft can slide on the surface of the second transmission shaft, and it will not move to the outside of the second transmission shaft. Therefore, it is clear that... Figure 8 Under the influence of gravity, the third drive shaft eventually ends up above the drive ring. When the steel wire pulls the circular plate, the second drive shaft, and the third drive shaft downwards, the third drive shaft moves to the same height as the circular ring. When the circular ring rotates to the position where it contacts the third drive shaft, the third drive shaft limits the circular ring and the lifting plate, preventing the lifting plate from rotating. At this point, the threaded connection between the lifting plate and the first threaded shaft drives the lifting plate upwards until it contacts the extension shaft, pushing the extension shaft and the circular plate upwards until the circular plate compresses the force spring. Thus, it can be understood that if the stirring shaft body rotates continuously, it will convert the rotational power into an upward force through the threaded connection between the lifting plate and the first threaded shaft, continuously applying upward force to the lifting plate. The lifting plate can continuously provide tension to the stirring shaft body through the steel wire, providing a continuous tension to resist centripetal force. At this time, the resistance to the rotation of the stirring shaft body will increase until the anti-burn-out function in the first step motor is activated, stopping the application of power to the stirring shaft body. This achieves the purpose of monitoring the deformation of the stirring shaft body. S2: When the lifting plate moves upward, it drives the circular ring and the spiral shaft to move upward synchronously. It's important to understand that when the lifting plate is not limited by the third transmission shaft, the circular ring, lifting plate, and spiral shaft will rotate synchronously. When the lifting plate is limited by the third transmission shaft, it will still move upward, but the spiral shaft will continue to rotate smoothly under the action of the lifting plate. Furthermore, the power from the upward movement of the lifting plate can still be transmitted to the spiral shaft through the circular ring, causing the spiral shaft to move upward. When the spiral shaft moves upward, the spiral stripes on the surface of the spiral shaft and the spiral grooves on the inner wall of the spiral cylinder drive the spiral cylinder to rotate, which in turn drives the second threaded shaft to rotate. The second threaded shaft is threadedly connected to the transmission gear plate. Therefore, the transmission gear plate can move upward, and the teeth on the surface of the transmission gear plate can drive the transmission gear to rotate 90 degrees, which will rotate the support plate 90 degrees. At this time, the bullseye bearing fixed on one side of the support plate will contact the inner wall of the jacketed cooling reactor, which can provide support for the lower half of the stirring shaft. It can be understood that the bullseye bearing is made of Hastelloy, which can avoid pharmaceutical corrosion and will not affect the synthesis of drugs. The power received by the support plate when rotating is indirectly from the power of the lifting plate rising, and the power of the lifting plate rising comes from the power received by the stirring shaft body when rotating. Therefore, the support plate has enough power to push the lower half of the stirring shaft body to maintain balance, thus providing sufficient support for the stirring shaft body. S3: When the circular plate pushes the positioning shaft upward, the positioning shaft will contact the delay button, thus triggering the delay button. After the delay button is triggered, as the positioning shaft continues to move upward, the contraction spring will smoothly contract. After a period of time, the delay button will transmit an electrical signal to the second stepper motor via a wire. The second stepper motor drives the third threaded shaft to rotate. When the third threaded shaft rotates, it will use its threaded connection with the moving block to drive the moving block and the sliding toothed plate to move laterally. In conjunction with the meshing relationship between the sliding toothed plate and the fixing bolt, it can drive the fixing bolt to rotate. This allows the fixing bolt to be removed from the rectangular plate and the jacketed cooling reactor body. It is important to understand that after the delay button is pressed, it will only transmit an electrical signal to the second stepper motor via a wire after a period of time. During this period, the resistance to the rotation of the stirring shaft body will be monitored by the monitoring unit. The effect greatly increases, and the first stepper motor will stop applying power to the stirring shaft body. This ensures that the stirring shaft body has stopped running when the fixing bolts are removed. Then, the operator applies rotational power to the rotating frame, causing it to rotate around the second short axis. Once the delay button is no longer above the stirring shaft body, the stirring shaft body and rectangular plate can be disassembled as a whole. Before disassembly, since the stabilizing unit still provides support to the stirring shaft, it is necessary to control the first stepper motor to run in reverse. During this process, the first stepper motor runs at a relatively slow speed. It is only necessary to reset the lifting plate and further drive the support plate to reset. In addition, when the stirring shaft body moves upward, the stirring plate will contact the inner top wall of the jacketed cooling reactor body. Therefore, the stirring plate will retract into the interior of the stirring shaft body to avoid the stirring plate affecting the disassembly of the stirring shaft body.
[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention sets up a monitoring unit, which can monitor whether the stirring shaft body is deformed. When the stirring shaft body is in the initial stage of deformation, the steel wire can provide tension to the stirring shaft body, thereby providing a tension against the centripetal force to the stirring shaft body at all times, reducing the influence of the centripetal force on the deformation of the stirring shaft body.
[0017] 2. By setting up a stabilizing unit, the present invention can provide support for the lower half of the stirring shaft body, so that the lower half of the stirring shaft body indirectly contacts the inner wall of the cooling reactor body, thereby reducing the speed at which the stirring shaft body is completely damaged.
[0018] 3. The present invention uses a disassembly mechanism to disassemble the damaged stirring shaft body. By setting up a monitoring unit, a stabilizing unit and a disassembly mechanism, it can effectively avoid the problem of the stirring shaft body breaking due to aging during long-term use of the equipment and colliding with the inner wall of the jacketed cooling reactor, which would cause damage to the jacketed cooling reactor.

[0021] 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.
[0022] Example 1: Please refer to Figures 1-11 The present invention provides a technical solution: a cooling device for chemical drugs. The present invention makes corresponding improvements to the technical problems mentioned in the background art, including a jacketed cooling reactor body 1, a protective mechanism 2 provided above the jacketed cooling reactor body 1, and a disassembly mechanism 3 provided inside the jacketed cooling reactor body 1. The protective mechanism 2 includes a monitoring unit 21, which is located above the jacketed cooling reactor body 1. The monitoring unit 21 can monitor the fracture state of the stirring shaft. The protective mechanism 2 also includes a stabilizing unit 22, which is located inside the jacketed cooling reactor body 1. The stabilizing unit 22 can increase the stability of the lower half of the stirring shaft. The disassembly mechanism 3 can speed up the disassembly of abnormal stirring shafts.
[0023] As a further definition of the protective mechanism 2 of the present invention, the monitoring unit 21 includes a rectangular plate 2111. The outer surface of the rectangular plate 2111 is in contact with the outer surface of the jacketed cooling reactor body 1. A force-bearing plate 2105 is fixedly connected to the upper surface of the rectangular plate 2111. A force-bearing spring 2109 is fixedly connected to the bottom surface of the force-bearing plate 2105. A circular plate 2107 is fixedly connected to the bottom end of the force-bearing spring 2109. A rotating plate 2114 is rotatably connected to the inner wall of the circular plate 2107. Two sets of extension shafts 2121 are fixedly connected to the bottom surface of the circular plate 2107. A first transmission shaft 2115 is fixedly connected to the bottom surface of the rotating plate 2114. A second transmission shaft 2117 is fixedly connected to the bottom surface of the circular plate 2107. A third transmission shaft 2118 is slidably connected to the outer surface of the second transmission shaft 2117. A stirring shaft body 2108 is rotatably connected to the inner wall of the rectangular plate 2111. A first threaded shaft 2119 is fixedly connected to the inner wall of 108. The outer surface of the first transmission shaft 2115 is slidably connected to the inside of the first threaded shaft 2119. A lifting plate 2116 is threadedly connected to the outer surface of the first threaded shaft 2119. A transmission ring 2123 is fixedly connected to the upper surface of the lifting plate 2116. A steel wire 2120 is fixedly connected to the inner bottom wall of the stirring shaft body 2108 and the bottom surface of the rotating plate 2114. The steel wire 2120 is set in the inner cavity of the first threaded shaft 2119. By setting a monitoring unit 21, the monitoring unit 21 can monitor whether the stirring shaft body 2108 has deformed. When the stirring shaft body 2108 is in the initial stage of deformation, the steel wire 2120 can provide tension to the stirring shaft body 2108. Thus, it can always provide a tension against the centripetal force to the stirring shaft body 2108, reducing the influence of the centripetal force on the deformation of the stirring shaft body 2108.
[0024] Please see Figure 4 Two positioning shafts 2106 are fixedly connected to the upper surface of the circular plate 2107. The outer surface of each positioning shaft 2106 is slidably connected to the inside of the force-bearing plate 2105. By providing the positioning shafts 2106, the presence of the positioning shafts 2106 can provide positional limitation for the circular plate 2107.
[0025] Please see Figure 1A mounting bracket 2101 is fixedly connected to the upper surface of the jacketed cooling reactor body 1. A first stepper motor 2102 is fixedly connected to the inner wall of the mounting bracket 2101. A first gear 2103 is fixedly connected to the output end of the first stepper motor 2102. A second gear 2110 is fixedly connected to the outer surface of the stirring shaft body 2108. The teeth of the second gear 2110 mesh with the teeth of the first gear 2103. By setting the mounting bracket 2101, the mounting bracket 2101 can provide a fixing force to the first stepper motor 2102. The operation of the first stepper motor 2102 can drive the first gear 2103 to rotate. In conjunction with the meshing relationship with the second gear 2110, it can drive the stirring shaft body 2108 to rotate.
[0026] Please see Figure 1 The bottom surface of the jacketed cooling reactor body 1 is fixedly connected with three support legs 2122, and the upper surface of the jacketed cooling reactor body 1 is fixedly connected with a feed pipe 2104. The inner wall of the stirring shaft body 2108 is rotatably connected with several identical spring return shafts 2113. The outer surface of each spring return shaft 2113 is fixedly connected with a stirring plate 2112. By providing support legs 2122, the support legs 2122 can provide support force for the equipment, and the spring return shafts 2113 can ensure that the stirring plate 2112 will be in the unfolded state when it is not subjected to other forces.
[0027] The specific implementation of this embodiment is as follows: When the equipment is in normal use, the stirring shaft body 2108 will rotate under the action of the first step motor 2102, stirring the medicine inside the jacketed cooling reactor body 1. When the stirring shaft body 2108 rotates, it will synchronously drive the lifting plate 2116 to rotate. It should be understood that although the lifting plate 2116 is threadedly connected to the first threaded shaft 2119, the lifting plate 2116 is not subject to any structural limitations at this time. Therefore, the lifting plate 2116 will rotate together with the first threaded shaft 2119 and the stirring shaft body 2108. In addition, the steel wire 2120 fixed to the inner wall of the stirring shaft body 2108 will also rotate synchronously. To prevent the steel wire 2120 from tightening itself, the rotating plate 2114 fixed to the top of the steel wire 2120 will rotate under the combined action of the first transmission shaft 2115 and the first threaded shaft 2119. Therefore, the steel wire 2120 can rotate along with the rotation of the stirring shaft body 2108, and the rotating plate 2114 is rotatably connected to the inner wall of the circular plate 2107. Thus, the rotation of the rotating plate 2114 does not affect the state of the circular plate 2107. When the stirring shaft body 2108 shows signs of breakage during use, it will slightly deform in the initial stage of the breakage. This slight deformation will pull the steel wire 2120, causing the rotating plate 2114 to move downwards. Consequently, the rotating plate 2114 will stretch the force spring 2109. When the rotating plate 2114 moves downwards, it will cause the third transmission shaft 2118 to move downwards. It is important to understand that the third transmission shaft 2118 can slide on the surface of the second transmission shaft 2117, and it will not move to the outside of the second transmission shaft 2117. Therefore, it is clear that... Figure 8Under the influence of gravity, the third drive shaft 2118 eventually reaches a position above the drive ring 2123. When the steel wire 2120 pulls the circular plate 2107, the second drive shaft 2117, and the third drive shaft 2118 downwards, the third drive shaft 2118 will move to the same height as the circular ring 2204. When the circular ring 2204 rotates to the position where it contacts the third drive shaft 2118, the third drive shaft 2118 will limit the circular ring 2204 and the lifting plate 2116, preventing the lifting plate 2116 from rotating. At this time, the threaded connection between the lifting plate 2116 and the first threaded shaft 2119 will drive the lifting plate 2116 upwards until it contacts the extension shaft 2121, pushing the extension shaft 2121 and the circular plate... 2107 moves upward until the circular plate 2107 compresses the force spring 2109. It can be understood that if the stirring shaft body 2108 keeps rotating, it will convert the rotational power into an upward moving force through the threaded connection between the lifting plate 2116 and the first threaded shaft 2119, continuously applying upward power to the lifting plate 2116. The lifting plate 2116 can continuously provide tension to the stirring shaft body 2108 through the steel wire 2120, continuously providing tension to the stirring shaft body 2108 to resist the centripetal force. At this time, the resistance to the rotation of the stirring shaft body 2108 will become greater and greater until the anti-burn-out function in the first step motor 2102 is activated, stopping the application of power to the stirring shaft body 2108. This achieves the purpose of monitoring the deformation of the stirring shaft body 2108.
[0028] Example 2: Please refer to Figure 6 , Figure 8 , Figures 10-12 The present invention provides a technical solution: a cooling device for chemical drugs, and the present invention makes corresponding improvements to address the technical problems mentioned in the background art.
[0029] As a further definition of the protective mechanism 2 of the present invention, the stabilizing unit 22 includes two sets of first short shafts 2208, with two in each set. The outer surface of each first short shaft 2208 is rotatably connected to the inner wall of the stirring shaft body 2108. A support plate 2201 is fixedly connected to the outer surface of each first short shaft 2208. A bullseye bearing 2205 is fixedly connected to the upper surface of each support plate 2201. A transmission gear 2206 is fixedly connected to the outer surface of each first short shaft 2208. The teeth of each transmission gear 2206 mesh with a transmission gear plate 2209. The outer surface of each transmission gear plate 2209 is in contact with the outer surface of the stirring shaft body 2108. The inner wall of each transmission gear plate 2209 is threaded. The stirring shaft 2108 is connected to a second threaded shaft 2207. Each second threaded shaft 2207 is fixedly connected to a spiral cylinder 2203 at its top end. The outer surface of each spiral cylinder 2203 is rotatably connected to the inner wall of the stirring shaft body 2108. A spiral shaft 2202 is slidably connected inside each spiral cylinder 2203. The top ends of the two sets of spiral shafts 2202 are fixedly connected to a circular ring 2204. The outer surface of the circular ring 2204 is rotatably connected to the inner wall of the lifting plate 2116. By setting a stabilizing unit 22, the stabilizing unit 22 can provide support for the lower half of the stirring shaft body 2108, so that the lower half of the stirring shaft body 2108 indirectly contacts the inner wall of the cooling reactor body, reducing the speed at which the stirring shaft body 2108 is completely damaged.
[0030] The specific implementation of this embodiment is as follows: When the lifting plate 2116 moves upward, it will drive the circular ring 2204 and the spiral shaft 2202 to move upward synchronously. It should be understood that when the lifting plate 2116 is not limited by the third transmission shaft 2118, the circular ring 2204, the lifting plate 2116, and the spiral shaft 2202 will rotate synchronously. However, when the lifting plate 2116 is limited by the third transmission shaft 2118, the lifting plate 2116... It will move upwards, but the spiral shaft 2202 can still rotate smoothly under the action of the lifting plate 2116. Furthermore, the power of the lifting plate 2116 moving upwards can still be transmitted to the spiral shaft 2202 through the circular ring 2204, causing the spiral shaft 2202 to move upwards. When the spiral shaft 2202 moves upwards, the spiral stripes on the surface of the spiral shaft 2202 and the spiral grooves on the inner wall of the spiral cylinder 2203 can drive the spiral cylinder 2203 to rotate, thus driving the second thread. When shaft 2207 rotates, and the second threaded shaft 2207 is threadedly connected to the transmission gear plate 2209, the transmission gear plate 2209 can move upward. The teeth on the surface of the transmission gear plate 2209 can drive the transmission gear 2206 to rotate 90 degrees, which will rotate the support plate 2201 90 degrees. At this time, the bullseye bearing 2205 fixed on one side of the support plate 2201 will contact the inner wall of the jacketed cooling reactor, which can provide support for the lower half of the stirring shaft. It can be understood that the bullseye bearing 2205 is made of Hastelloy, which can avoid pharmaceutical corrosion and will not affect the synthesis of drugs. The power received by the support plate 2201 when rotating is indirectly from the upward power of the lifting plate 2116, and the upward power of the lifting plate 2116 comes from the power received by the stirring shaft body 2108 when rotating. Therefore, the support plate 2201 has enough power to push the lower half of the stirring shaft body 2108 to maintain balance, thus providing sufficient support for the stirring shaft body 2108.
[0031] Example 3: Please refer to Figures 1-5 The present invention provides a technical solution: a cooling device for chemical drugs, and the present invention makes corresponding improvements to address the technical problems mentioned in the background art.
[0032] As a further definition of the disassembly mechanism 3 of the present invention, the disassembly mechanism 3 includes two support blocks 303. The bottom surface of each support block 303 is fixedly connected to the upper surface of the jacketed cooling reactor body 1. The interiors of the two support blocks 303 and the interior of the fixing frame 2101 are slidably connected to two sliding toothed plates 306. The two sides of the fixing frame 2101 and the sides of the two support blocks 303 that are far apart from each other are fixedly connected to mounting blocks 310. The inner walls of each pair of mounting blocks 310 are rotatably connected to a third threaded shaft 307. The outer surface of each third threaded shaft 307 is threadedly connected to a moving block 311. One side of each moving block 311 is fixedly connected to one side of the sliding toothed plate 306. One of the support blocks 303 is a sliding toothed plate 306. The inner wall of block 303 is rotatably connected to a second short shaft 302. The outer surface of the second short shaft 302 is fixedly connected to a rotating frame 301. The bottom surface of the rotating frame 301 is fixedly connected to a contraction spring 308. The bottom end of the contraction spring 308 is fixedly connected to a delay button 309. The delay button 309 is located above one of the positioning shafts 2106. The damaged stirring shaft body 2108 can be disassembled using the disassembly mechanism 3. By setting up a monitoring unit 21, a stabilizing unit 22 and a disassembly mechanism 3, the problem of the stirring shaft body 2108 breaking due to aging during long-term use of the equipment and colliding with the inner wall of the jacketed cooling reactor, causing damage to the jacketed cooling reactor, can be effectively avoided.
[0033] Please see Figure 4 A circular shaft 304 is fixedly connected to the upper surface of the delay button 309. The outer surface of the circular shaft 304 is slidably connected to the inside of the rotating frame 301. The circular shaft 304 is located in the inner cavity of the retraction spring 308. By providing the circular shaft 304, the circular shaft 304 can apply a pushing force to the delay button 309.
[0034] Please see Figure 2 and Figure 4 The inner wall of the rectangular plate 2111 and the inner wall of the jacketed cooling reactor body 1 are connected by two sets of fixing bolts 305. Each set of fixing bolts 305 consists of two bolts, and the teeth of each fixing bolt 305 are engaged with the teeth of the sliding toothed plate 306. Two second stepper motors 312 are fixedly connected to the upper surface of the jacketed cooling reactor body 1. The output end of each second stepper motor 312 is fixedly connected to one end of the third threaded shaft 307. Each second stepper motor 312 is electrically connected to the delay button 309 through a wire. With the fixing bolts 305, the rectangular plate 2111 can be installed on the jacketed cooling reactor body 1, and the second stepper motors 312 can provide power for the rotation of the third threaded shaft 307.
[0035] The specific implementation of this embodiment is as follows: When the circular plate 2107 pushes the positioning shaft 2106 upward, the positioning shaft 2106 will contact the delay button 309, thus triggering the delay button 309. After the delay button 309 is triggered, as the positioning shaft 2106 continues to move upward, the contraction spring 308 will smoothly contract. After a period of time, the delay button 309 will transmit an electrical signal to the second stepper motor 312 through a wire. The second stepper motor 312 drives the third threaded shaft 307 to rotate. When the third threaded shaft 307 rotates, it will utilize the movement block... The threaded connection of 311 causes the moving block 311 and the sliding toothed plate 306 to move laterally. Combined with the meshing relationship between the sliding toothed plate 306 and the fixing bolt 305, the fixing bolt 305 can be rotated. This allows the fixing bolt 305 to be removed from the rectangular plate 2111 and the jacketed cooling reactor body 1. It's important to understand that after being pressed, the delay button 309 will only transmit an electrical signal to the second stepper motor 312 via a wire after a certain period. During this time, the resistance to the rotation of the stirring shaft body 2108 will... The monitoring unit 21 greatly increases the power output, and the first stepper motor 2102 will stop applying power to the stirring shaft body 2108. This ensures that the stirring shaft body 2108 has stopped operating when the fixing bolt 305 is disassembled. Subsequently, the operator applies rotational power to the rotating frame 301, causing it to rotate around the second short axis 302. Once the delay button 309 is no longer above the stirring shaft body 2108, the stirring shaft body 2108 and the rectangular plate 2111 can be disassembled as a whole. Before disassembly, since the stabilizing unit 22 is still... To provide support for the stirring shaft, it is necessary to control the first stepper motor 2102 to run in reverse. During this process, the first stepper motor 2102 runs at a relatively slow speed. It is only necessary to reset the lifting plate 2116, which in turn drives the support plate 2201 to reset. In addition, when the stirring shaft body 2108 moves upward, the stirring plate 2112 will contact the inner top wall of the jacketed cooling reactor body 1. Therefore, the stirring plate 2112 will retract into the interior of the stirring shaft body 2108 to avoid the stirring plate 2112 affecting the disassembly of the stirring shaft body 2108.
[0036] A method of using a cooling device for chemical pharmaceuticals includes the following steps: S1: When the equipment is in normal use, the stirring shaft body 2108 will rotate under the action of the first step motor 2102, stirring the medicine inside the jacketed cooling reactor body 1. When the stirring shaft body 2108 rotates, it will synchronously drive the lifting plate 2116 to rotate. It should be understood that although the lifting plate 2116 is threadedly connected to the first threaded shaft 2119, the lifting plate 2116 is not subject to any structural limit at this time. Therefore, the lifting plate 2116 will rotate together with the first threaded shaft 2119 and the stirring shaft body 2108. In addition, the steel wire 2120 fixed to the inner wall of the stirring shaft body 2108 will also rotate synchronously. To prevent the steel wire 2120 from tightening itself, the rotating plate 2114 fixed to the top of the steel wire 2120 will rotate under the combined action of the first drive shaft 2115 and the first threaded shaft 2119. Therefore, the steel wire 2120... 120 can rotate along with the stirring shaft body 2108, and the rotating plate 2114 is rotatably connected to the inner wall of the circular plate 2107. Therefore, the rotation of the rotating plate 2114 will not affect the state of the circular plate 2107. When the stirring shaft body 2108 shows signs of breakage during use, it will slightly deform in the initial stage of the breakage. This slight deformation will pull the steel wire 2120, which will then drive the rotating plate 2114 to move downwards. Consequently, the rotating plate 2114 will stretch the force spring 2109. As the rotating plate 2114 moves downwards, it will drive the third drive shaft 2118 to move downwards. It is important to understand that the third drive shaft 2118 can slide on the surface of the second drive shaft 2117, and it will not move to the outside of the second drive shaft 2117. Therefore, it is clear that... Figure 8Under the influence of gravity, the third drive shaft 2118 eventually reaches a position above the drive ring 2123. When the steel wire 2120 pulls the circular plate 2107, the second drive shaft 2117, and the third drive shaft 2118 downwards, the third drive shaft 2118 will move to the same height as the circular ring 2204. When the circular ring 2204 rotates to the position where it contacts the third drive shaft 2118, the third drive shaft 2118 will limit the circular ring 2204 and the lifting plate 2116, preventing the lifting plate 2116 from rotating. At this time, the threaded connection between the lifting plate 2116 and the first threaded shaft 2119 will drive the lifting plate 2116 upwards until it contacts the extension shaft 2121, pushing the extension shaft 2121 and the circular plate... 2107 moves upward until the circular plate 2107 compresses the force spring 2109. It can be understood that if the stirring shaft body 2108 keeps rotating, it will convert the rotational power into an upward moving force through the threaded connection between the lifting plate 2116 and the first threaded shaft 2119, continuously applying upward power to the lifting plate 2116. The lifting plate 2116 can continuously provide tension to the stirring shaft body 2108 through the steel wire 2120, continuously providing tension to the stirring shaft body 2108 to resist the centripetal force. At this time, the resistance to the rotation of the stirring shaft body 2108 will become greater and greater until the anti-burn-out function in the first step motor 2102 is activated, stopping the application of power to the stirring shaft body 2108. This achieves the purpose of monitoring the deformation of the stirring shaft body 2108. S2: When the lifting plate 2116 moves upward, it will drive the circular ring 2204 and the spiral shaft 2202 to move upward synchronously. It's important to understand that when the lifting plate 2116 is not limited by the third transmission shaft 2118, the circular ring 2204, lifting plate 2116, and spiral shaft 2202 will rotate synchronously. When the lifting plate 2116 is limited by the third transmission shaft 2118, it will move upward, but the spiral shaft 2202 will still rotate smoothly under the action of the lifting plate 2116. Furthermore, the power from the upward movement of the lifting plate 2116 can still be transmitted to the spiral shaft 2202 through the circular ring 2204, causing the spiral shaft 2202 to move upward. When the spiral shaft 2202 moves upward, the spiral stripes on its surface and the spiral grooves on the inner wall of the spiral cylinder 2203 will drive the spiral cylinder 2203 to rotate, causing the spiral cylinder 2203 to drive the second threaded shaft 2207 to rotate. The threaded connection between the threaded shaft 2207 and the transmission gear plate 2209 allows the transmission gear plate 2209 to move upwards. The teeth on the surface of the transmission gear plate 2209 can drive the transmission gear 2206 to rotate 90 degrees, which will rotate the support plate 2201 90 degrees. At this time, the bullseye bearing 2205 fixed on one side of the support plate 2201 will contact the inner wall of the jacketed cooling reactor, providing support for the lower half of the stirring shaft. It is understood that the bullseye bearing 2205 is made of Hastelloy, which can avoid pharmaceutical corrosion and will not affect the synthesis of drugs. The power received by the support plate 2201 when rotating is indirectly from the upward power of the lifting plate 2116, and the upward power of the lifting plate 2116 comes from the power received by the stirring shaft body 2108 when rotating. Therefore, the support plate 2201 has enough power to keep the lower half of the stirring shaft body 2108 in balance, thus providing sufficient support for the stirring shaft body 2108. S3: When the circular plate 2107 pushes the positioning shaft 2106 upward, the positioning shaft 2106 will contact the delay button 309, thus triggering the delay button 309. After the delay button 309 is triggered, as the positioning shaft 2106 continues to move upward, the contraction spring 308 will contract smoothly. After a period of time, the delay button 309 will transmit an electrical signal to the second stepper motor 312 through a wire. The second stepper motor 312 drives the third threaded shaft 307 to rotate. When the third threaded shaft 307 rotates, it will utilize the threaded connection with the moving block 311. The connection causes the moving block 311 and the sliding toothed plate 306 to move laterally. Combined with the meshing relationship between the sliding toothed plate 306 and the fixing bolt 305, the fixing bolt 305 can be rotated. This allows the fixing bolt 305 to be removed from the rectangular plate 2111 and the jacketed cooling reactor body 1. It's important to understand that after being pressed, the delay button 309 will only transmit an electrical signal to the second stepper motor 312 via a wire after a certain period. During this time, the resistance to the rotation of the stirring shaft body 2108 will be felt in the monitoring unit 2. The effect of step 1 is greatly increased, and the first stepper motor 2102 will stop applying power to the stirring shaft body 2108. This ensures that the stirring shaft body 2108 has stopped running when the fixing bolt 305 is disassembled. Subsequently, the operator applies rotational power to the rotating frame 301, causing it to rotate around the second short shaft 302. Once the delay button 309 is no longer above the stirring shaft body 2108, the stirring shaft body 2108 and the rectangular plate 2111 can be disassembled as a whole. Before disassembly, since the stabilizing unit 22 is still applying power to the stirring shaft body 2108, the stirring shaft body 2108 and the rectangular plate 2111 can be disassembled as a whole. The shaft provides support, therefore, it is necessary to control the first stepper motor 2102 to run in reverse. During this process, the first stepper motor 2102 runs at a relatively slow speed. It is only necessary to reset the lifting plate 2116, which in turn drives the support plate 2201 to reset. In addition, when the stirring shaft body 2108 moves upward, the stirring plate 2112 will contact the inner top wall of the jacketed cooling reactor body 1. Therefore, the stirring plate 2112 will retract into the interior of the stirring shaft body 2108 to avoid the stirring plate 2112 affecting the disassembly of the stirring shaft body 2108.

The output end of each second stepper motor (312) is fixedly connected to one end of the third threaded shaft (307).

6. The method of using the cooling device for chemical pharmaceuticals according to claim 5, characterized in that: Specifically, the following steps are included: S1: When the equipment is in normal use, the stirring shaft body (2108) will rotate under the action of the first step motor (2102), which will stir the medicine inside the jacketed cooling reactor body (1). When the stirring shaft body (2108) rotates, it will synchronously drive the lifting plate (2116) to rotate. It should be understood that although the lifting plate (2116) is threadedly connected to the first threaded shaft (2119), the lifting plate (2116) is not limited by any structure at this time. Therefore, the lifting plate (2116) will rotate together with the first threaded shaft (2119) and the stirring shaft body (2108). In addition, the steel wire (2120) fixed on the inner wall of the stirring shaft body (2108) will also rotate synchronously. In order to avoid The steel wire (2120) is tightened by itself. The rotating plate (2114) fixed at the top of the steel wire (2120) will rotate under the combined action of the first drive shaft (2115) and the first threaded shaft (2119). Therefore, the steel wire (2120) can rotate with the rotation of the stirring shaft body (2108). The rotating plate (2114) is rotatably connected to the inner wall of the circular plate (2107). Therefore, the rotation of the rotating plate (2114) will not affect the state of the circular plate (2107). When the stirring shaft body (2108) shows signs of breakage during use, the stirring shaft body (2108) will slightly deform in the early stage of the breakage. The slight deformation of the stirring shaft body (2108) will pull the steel wire (2120), and the steel wire (2120) will... The rotating plate (2114) moves downward, causing the spring (2109) to stretch. As the rotating plate (2114) moves downward, it also causes the third drive shaft (2118) to move downward. It's important to understand that the third drive shaft (2118) can slide on the surface of the second drive shaft (2117), and it will not move to the outside of the second drive shaft (2117). Therefore, it's clear that under the influence of gravity, the third drive shaft (2118) in Figure 8 will eventually be positioned above the drive ring (2123). When the steel wire (2120) pulls the circular plate (2107), the second drive shaft (2117), and the third drive shaft (2118) downward, The third drive shaft (2118) will move to the same height as the circular ring (2204). When the circular ring (2204) rotates to the position where it contacts the third drive shaft (2118), the third drive shaft (2118) will limit the circular ring (2204) and the lifting plate (2116), preventing the lifting plate (2116) from rotating. At this time, the threaded connection between the lifting plate (2116) and the first threaded shaft (2119) will drive the lifting plate (2116) to move upward until the lifting plate (2116) contacts the extension shaft (2121), pushing the extension shaft (2121) and the circular plate (2107) to move upward until the circular plate (2107) squeezes the force spring (2109). Thus, it can be understood that...If the stirring shaft body (2108) rotates continuously, the rotational power will be converted into an upward moving force through the threaded connection between the lifting plate (2116) and the first threaded shaft (2119), continuously applying upward force to the lifting plate (2116). The lifting plate (2116) can continuously provide tension to the stirring shaft body (2108) through the steel wire (2120), continuously providing the stirring shaft body (2108) with tension to resist centripetal force. At this time, the resistance to rotation of the stirring shaft body (2108) will become greater and greater until the anti-burn-out function in the first stepper motor (2102) is activated, stopping the application of power to the stirring shaft body (2108). This achieves the purpose of monitoring the deformation of the stirring shaft body (2108). S2: When the lifting plate (2116) moves upward, it will drive the circular ring (2204) and the spiral shaft (2202) to move upward synchronously. It's important to understand that when the lifting plate (2116) is not limited by the third drive shaft (2118), the circular ring (2204), the lifting plate (2116), and the spiral shaft (2202) will rotate synchronously. However, when the lifting plate (2116) is limited by the third drive shaft (2118), it will move upward, but the spiral shaft (2204) will not move upward. 2) It can still rotate smoothly under the action of the lifting plate (2116), and the power of the lifting plate (2116) moving upward can still be transmitted to the spiral shaft (2202) through the circular ring (2204), driving the spiral shaft (2202) to move upward. When the spiral shaft (2202) moves upward, the spiral stripes on the surface of the spiral shaft (2202) and the spiral grooves opened on the inner wall of the spiral cylinder (2203) can drive the spiral cylinder (2203) to rotate, so that the spiral cylinder (2203) drives the second threaded shaft (2207). The second threaded shaft (2207) rotates, and the second threaded shaft (2207) is threadedly connected to the transmission gear plate (2209). Therefore, the transmission gear plate (2209) can move upward, and the teeth on the surface of the transmission gear plate (2209) can drive the transmission gear (2206) to rotate ninety degrees, which will rotate the support plate (2201) ninety degrees. At this time, the bullseye bearing (2205) fixed on one side of the support plate (2201) will contact the inner wall of the jacketed cooling reactor, which can provide support for the lower half of the stirring shaft. Here it can be understood that the bullseye bearing (2205) 205) is made of Hastelloy, which can avoid pharmaceutical corrosion and will not affect the synthesis of drugs. The power received by the support plate (2201) when it rotates is indirectly from the power of the lifting plate (2116) rising. The power of the lifting plate (2116) rising comes from the power received by the stirring shaft body (2108) when it rotates. Therefore, the support plate (2201) has enough power to push the lower half of the stirring shaft body (2108) to maintain balance, thus providing sufficient support for the stirring shaft body (2108). S3: When the circular plate (2107) pushes the positioning shaft (2106) upward, the positioning shaft (2106) will contact the delay button (309), thus triggering the delay button (309). The delay button (309) will move upward under the action of the circular shaft (304). After the delay button (309) is triggered, as the positioning shaft (2106) continues to move upward, the contraction spring (308) will contract smoothly. After a period of time, the delay button (309) will transmit an electrical signal to the second stepper motor (312) through the wire. The second stepper motor (312) drives the third threaded shaft (307) to rotate, and the third threaded shaft... When the shaft (307) rotates, it will use the threaded connection with the moving block (311) to drive the moving block (311) and the sliding toothed plate (306) to move laterally. In conjunction with the meshing relationship between the sliding toothed plate (306) and the fixing bolt (305), the fixing bolt (305) can be driven to rotate. Thus, the fixing bolt (305) can be removed from the rectangular plate (2111) and the jacketed cooling reactor body (1). It should be understood that after the delay button (309) is pressed, it will only transmit an electrical signal to the second stepper motor (312) through the wire after a period of time. During this period, the stirring shaft body (2111) will rotate. 108) The resistance to rotation will increase significantly under the action of the monitoring unit (21), and the first stepper motor (2102) will stop applying power to the stirring shaft body (2108). This ensures that the stirring shaft body (2108) has stopped running when the fixing bolt (305) is disassembled. Subsequently, the operator applies rotational power to the rotating frame (301) to make it rotate around the second short axis (302), so that the delay button (309) is no longer above the stirring shaft body (2108). The stirring shaft body (2108) and the rectangular plate (2111) can then be disassembled as a whole. Before disassembly, due to the stabilizing unit (22) It still provides support for the stirring shaft. Therefore, it is necessary to control the first stepper motor (2102) to run in reverse. During this process, the first stepper motor (2102) runs at a slower speed. It is only necessary to reset the lifting plate (2116) and further drive the support plate (2201) to reset. In addition, when the stirring shaft body (2108) moves upward, the stirring plate (2112) will contact the inner top wall of the jacketed cooling reactor body (1). Therefore, the stirring plate (2112) will retract into the interior of the stirring shaft body (2108) to avoid the stirring plate (2112) from affecting the disassembly of the stirring shaft body (2108).
