Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment technology, specifically to a controllable pressure-stabilized reactor for pharmaceutical production. Background Technology

[0002] In the pharmaceutical manufacturing process, the reaction vessel is one of the key pieces of equipment, playing an important role in providing a chemical reaction site, controlling reaction conditions, and ensuring product quality. The reaction vessel can provide suitable temperature, pressure, and stirring conditions for the chemical reactions in pharmaceutical manufacturing to ensure that the chemical reactions can proceed according to the predetermined path, thereby obtaining the desired drugs or intermediates.

[0003] However, when feeding materials into the reactor, the raw materials are usually put in through the feed inlet at the top of the reactor. Since the reactor is generally quite tall, putting the raw materials in from a height will cause a large impact force on the inside of the reactor. Furthermore, using sharp or heavy raw materials will increase the impact on the reactor. Over time, this will cause the inner wall to become thinner or develop dents, affecting the structural integrity and service life of the reactor. In addition, when the inner wall of the reactor is damaged, the metal or other materials on the inner wall will come into direct contact with the raw materials, causing changes in the chemical properties of the raw materials.

[0004] Therefore, this invention proposes a controllable pressure-stabilized reactor for pharmaceutical production to compensate for and improve the shortcomings of the prior art. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. This invention, by causing multiple electric push rods to output downwards when the raw material is placed into the feeding component, can smoothly transport the raw material in the feeding component into the reaction chamber. This can reduce the damage caused by the falling raw material to the reaction chamber, protect the integrity of the inner wall of the reaction chamber, and prevent impurities from the damaged inner wall from contaminating the raw material, thus helping the raw material to react under optimal conditions.

[0018] 2. The present invention enables the first telescopic component to move downward when the gear rotates, thereby increasing the internal volume of the first telescopic component. This allows the first telescopic component to load more raw materials into the reaction chamber at once, reducing the frequency and time of feeding. It also helps to reduce the time difference in batch feeding of raw materials, making the quality of raw materials after reaction more stable. Furthermore, by observing the measuring component when the indicator moves downward, the telescopic length of the first telescopic component can be directly observed, allowing the staff to more accurately judge the amount of raw materials to be fed, thus avoiding the situation of excessive or insufficient raw materials.

[0019] 3. This invention enables the buffer to absorb part of the impact force of the falling material when it falls onto the buffer, further slowing down the falling speed of the material. It also reduces the impact and vibration on the equipment when the material falls, extending the service life of the equipment and reducing maintenance costs.

[0020] 4. The present invention uses the shrink rope to cause the storage spring to move the buffer outward when it shrinks, so that the light raw material is not blocked by the buffer when it is poured into the first telescopic member, and the raw material can fall accurately into the bottom of the first telescopic member and then enter the reaction chamber, reducing the time wasted in the delivery process.

[0040] Embodiments of the present invention

[0041] refer to Figures 1 to 8As shown, a controllable pressure-stabilized reactor for pharmaceutical production includes a support frame 1. A reaction chamber 11 is fixedly connected to the inner side of the top of the support frame 1, which supports and fixes the reaction chamber 11. A support plate 12 is fixedly connected to the outer surface of the top of the reaction chamber 11. A rotating component 13 is rotatably connected to the inner left side of the support plate 12, which restricts the rotation of the rotating component 13 within the support plate 12. A first screw 14 is rotatably connected to the upper surface of the rotating component 13, which drives the rotating component 13 to rotate simultaneously. A sealing component 15 is threadedly connected to the outer surface of the first screw 14, which drives the sealing component 15 to move up and down. The upper surface of the sealing component 15 slides through the outer surface of the top of the rotating component 13. A stirring device 16 is fixedly connected to the bottom of the reaction chamber 11. The stirring device 16 is composed of a motor and a stirring rod. The stirring device 16 is used to stir the raw materials inside the reaction chamber 11. An L-shaped rod 161 is fixedly connected to the outer surface of the rotating component 13. The rotating component 13 is used to drive the L-shaped rod 161 to rotate simultaneously. Multiple electric push rods 17 are fixedly connected to the inner side of the top of the L-shaped rod 161. The L-shaped rod 161 is used to support the multiple electric push rods 17 and can drive the multiple electric push rods 17 to rotate. A support ring 18 is fixedly connected to the output end of the multiple electric push rods 17. The multiple electric push rods 17 are used to drive the support ring 18 to move up and down. A first telescopic component 19 is rotatably connected to the bottom of the support ring 18. The support ring 18 is used to drive the first telescopic component 19. Simultaneously moving, a protective ring 191 is fixedly connected to the bottom of the first telescopic member 19, which is used to protect the first telescopic member 19. Another first telescopic member 19 is fixedly connected to the bottom of the protective ring 191, and another protective ring 191 is fixedly connected to the bottom of the other first telescopic member 19. Multiple arc-shaped grooves are formed through the outer surface of the first telescopic member 19. A feeding member 110 is fixedly connected to the bottom of the other protective ring 191. A baffle plate 111 is rotatably connected to the inner side of the bottom of the feeding member 110. The baffle plate 111 is used to transport the raw materials inside the first telescopic member 19 to the inside of the reaction chamber 11. A baffle member 112 is symmetrically slidably connected to the center of the bottom of the baffle plate 111. The inner side of the lower surface of the baffle member 112 is inclined outward. The upper surface of the outer end of the blocking member 112 is inclined inward. The outer side of the blocking member 112 is engaged with the inner side of the bottom of the unloading member 110. The blocking member 112 is used to block the blocking plate 111 and prevent the blocking plate 111 from flipping open. The lower surface of the blocking plate 111 is pressed and fitted with the outer surface of the top of the reaction chamber 11. A compression spring 113 is fixedly connected between the inner sides of the two blocking members 112. The compression spring 113 is used to drive the blocking member 112 to move back to its original position. A piston rod 116 is fixedly connected to the front side of the blocking member 112. The blocking member 112 is used to drive the piston rod 116 to move simultaneously. A gas storage tank 115 is slidably connected to the outer surface of the piston rod 116. The outer surface of the gas storage tank 115 is fixedly connected to the lower surface of the blocking plate 111.The gas storage tank 115 is used to slow down the movement speed of the piston rod 116. An air outlet is provided through the inner side of the gas storage tank 115. A compression ring 114 is fixedly connected to the center of the upper surface of the stirring rod of the support member 16. The blocking member 112 is used to press against the upper surface of the compression ring 114, causing the blocking member 112 to contract inward. When the raw material is placed into the feeding member 110, the multi-section electric push rod 17 extends downward, smoothly conveying the raw material in the feeding member 110 into the reaction chamber 11. Then, the bottom of the blocking member 112 adheres to the compression ring 114, causing the blocking member 112 to contract inward. At this time, the blocking plate 111 flips downward, allowing the raw material to fall into the inner side of the reaction chamber 11, reducing damage to the reaction chamber 11 caused by the falling raw material and protecting the integrity of the inner wall of the blocking plate 111.

[0042] refer to Figure 9 and Figure 10 As shown, a controllable pressure-stabilized reactor for pharmaceutical production has a connecting frame 2 fixedly connected to the right side of the top of an L-shaped rod 161. A rack 21 is fixedly connected to the bottom right side of the connecting frame 2. A gear 22 meshes with the left side of the rack 21. The gear 22 is used to rotate itself when moving up and down by meshing with the rack 21. A rotating rod 221 is fixedly connected to the front side of the gear 22. The outer surface of the rotating rod 221 is rotatably connected to the upper surface of a support ring 18. The gear 22 is used to drive the rotating rod 221 to rotate simultaneously. A pull rope 25 is fixedly wound around the outer surface of the front side of the rotating rod 221. When the rotating rod 221 rotates, it is used to drive the pull rope 25 to disengage from the outer surface of the rotating rod 221. The outer surface of the pull rope 25 is slidably connected to the inner side of the upper surface of the support ring 18. The inner side of the upper surface of the support ring 18 is used to limit the sliding of the outer surface of the pull rope 25 on the inner side of the upper surface of the support ring 18. The bottom end of the pull rope 25 is fixed. The first telescopic component 19 is fixedly connected to the outer surface of the bottom of another protective ring 191. When the pull rope 25 is released from the outer surface of the rotating rod 221, it drives the first telescopic component 19 to unfold downwards, so that the first telescopic component 19 can load more raw materials into the reaction chamber 11 at one time, reducing the number of times and time of frequent feeding, improving production efficiency, and also helping to reduce the time difference of batch feeding of raw materials, making the quality of raw materials after reaction more stable. A measuring component 23 is fixedly connected to the front side of the rack 21. The measuring component 23 is provided with multiple scale lines on the front side. The measuring component 23 is used to observe the degree of unfolding of the first telescopic component 19. An indicator 24 is fixedly connected to the front side of the upper surface of the support ring 18. The support ring 18 is used to drive the indicator 24 to descend at the same time. The indicator 24 is used to point to the scale lines on the front side of the measuring component 23, so that the extension length of the first telescopic component 19 can be intuitively known, thereby controlling the amount of raw materials fed.

[0043] refer to Figures 11 to 13As shown, a controllable pressure-stabilized reactor for pharmaceutical production has a protective ring 191 with two ends of an arc-shaped groove fixedly connected to both ends. The protective ring 191 is used to drive the second telescopic components 3 to move simultaneously. A push rod 301 is fixedly connected to the inner side of the output end of each second telescopic component 3. The output end of the second telescopic component 3 is used to drive the push rod 301 to slide simultaneously. A fixing member 31 is fixedly connected between the inner sides of the push rod 301. The two ends of the fixing member 31 are slidably connected within the arc-shaped groove of the protective ring 191. The push rod 301 is used to drive the fixing member 301 to move simultaneously. The components 31 move simultaneously, and the inner side of each fixed component 31 is rotatably connected to a buffer component 33. The buffer component 33 is used to buffer the falling raw materials. Both ends of the buffer component 33 near the fixed component 31 are fixedly sleeved with torsion springs 32. The outer end of the torsion spring 32 is fixedly connected to the inner side of the fixed component 31. The torsion spring 32 is used to drive the buffer component 33 to swing back. When the raw materials are put into the reaction chamber 11, the raw materials will fall on the buffer component 33, which can further slow down the falling speed of the raw materials and reduce the mutual collision between the raw materials and the inside of the feeding component 110.

[0044] refer to Figures 14 to 16 As shown, a controllable pressure-stabilized reactor for pharmaceutical production has two winding devices 4 fixedly connected to the outer surface of the first telescopic member 19. Each winding device 4 has a slidably connected retraction rope 41 on its outer surface. The winding devices 4 are used to tighten or loosen the retraction rope 41. The outer surface of the retraction rope 41 is slidably connected to the inside of the output end of the second telescopic member 3. The retraction rope 41 is used to retract the output end of the second telescopic member 3 inward. A storage spring 42 is fixedly connected to the outer end of the push rod 301 near the protective ring 191. The outer end of the storage spring 42 is fixedly connected to the outer surface of the protective ring 191. When the retraction rope 41 retracts, the storage spring 42 causes the buffer 33 to move outward, so that very light raw materials poured into the first telescopic member 19 are not blocked by the buffer 33, allowing the raw materials to accurately fall to the bottom of the first telescopic member 19 and then enter the reaction chamber 11, reducing the time wasted during the feeding process.

[0045] The complete working principle and steps of the above embodiments are as follows:

[0046] refer to Figures 1 to 8 As shown, when the reactor is in its initial state, the sealing member 15 is not yet attached to the top of the reaction chamber 11, the support member 16 is in the closed state, the multi-section electric push rod 17 is in the retracted state, the outer end of the blocking member 112 is engaged with the bottom of the unloading member 110, and the compression spring 113 is in the naturally relaxed state.

[0047] When the operator uses the reactor for pharmaceutical production, the raw materials are first fed into the support ring 18. The raw materials pass through the protective ring 191 and fall into the discharge unit 110. At this time, the multi-section electric push rod 17 is activated. The output end of the multi-section electric push rod 17 drives the support ring 18 to move inwards towards the reaction chamber 11. As the support ring 18 slides downwards, it drives the protective ring 191 to move simultaneously via the first telescopic member 19. As the protective ring 191 moves downwards, it drives another protective ring 191 to move simultaneously via another first telescopic member 19. And as the other protective ring 191 moves downwards, it drives the discharge unit 110 to move simultaneously. The feeding component 110 moves the raw material to the bottom of the reaction chamber 11. As the feeding component 110 slides downwards, it also moves the blocking component 112. At this time, the inclined surface at the bottom of the blocking component 112 adheres to the lower surface of the extrusion ring 114. Due to the compression fit between the inclined surface at the bottom of the blocking component 112 and the outer surface of the extrusion ring 114, the blocking component 112 slides inwards at the bottom of the blocking plate 111, causing the outer end of the blocking component 112 to disengage from the bottom of the feeding component 110. As the blocking component 112 moves inwards, it also moves the piston rod 116. At this time, the piston rod 116 moves inwards inside the gas storage tank 115. The blocking component 112 moves inwards simultaneously... At this time, the compression spring 113 will also be moved to the squeezed state. At this time, the multi-section electric push rod 17 will be activated again, causing the output end of the multi-section electric push rod 17 to drive the support ring 18 to move upward. When the support ring 18 moves upward, it will drive the unloading part 110 to move simultaneously through the first telescopic part 19. As the unloading part 110 moves upward, it will drive the blocking part 112 to disengage from the compression ring 114. At this time, the compression spring 113 in the compressed state will drive the blocking parts 112 on both sides to slide outward. When the blocking parts 112 slide outward, it will drive the piston rod 116 to move simultaneously. Since the piston rod 116 is inside the air tank 115, the piston rod 116 and the piston rod 116 move simultaneously. As the barrier 112 moves outward, it will cause the barrier 112 to move outward slowly. When the outer side of the barrier 112 engages with the bottom of the feeder 110, the barrier plate 111 will flip downward inside the feeder 110. At this time, the raw material inside the feeder 110 can be smoothly transported into the barrier plate 111 and then enter the reaction chamber 11 along the barrier plate 111. This can reduce the damage caused by the falling raw material to the reaction chamber 11, protect the integrity of the inner wall of the reaction chamber 11, and protect the integrity of the inner wall of the barrier plate 111. This can prevent impurities generated by the damage to the inner wall of the reaction chamber 11 from contaminating the raw material and help the raw material to react under the best conditions.

[0048] As the multi-section electric push rod 17 moves the support ring 18 upward, the support ring 18, through the first telescopic member 19, moves the protective ring 191 upward. The upward movement of the protective ring 191 simultaneously moves the unloading part 110, causing its bottom to move out of the reaction chamber 11. At this point, when the operator rotates the sealing member 15 clockwise, the sealing member 15, through the first screw 14, drives the rotating member 13 to rotate simultaneously. The rotating member 13, rotating clockwise inside the support plate 12, drives the L-shaped rod 161 to rotate simultaneously. The rotation of the L-shaped rod 161, through the multi-section electric push rod 17, drives the support ring 18 to rotate simultaneously, and the support ring 18, through the first telescopic member 19, drives the unloading part 110 to rotate simultaneously. When the feeder 110 rotates, it will cause the baffle plate 111 to move simultaneously. At this time, the bottom of the baffle plate 111 will adhere to the outer surface of the top of the reaction chamber 11, causing the baffle plate 111 to flip upward. When the baffle plate 111 flips upward, it will cause the baffle 112 to flip simultaneously. Since the outer ends of the baffle 112 are all inclined inward, when the baffle 112 flips upward, it will re-clamp back to the bottom of the feeder 110. As the rear end of the sealing member 15 rotates to the upper surface of the reaction chamber 11, the top of the first screw 14 is rotated, causing the sealing member 15 to move downward, so that the bottom of the rear side of the sealing member 15 is sealed and adhered to the bottom of the reaction chamber 11. At this time, the support member 16 is activated, so that the support member 16 stirs the raw materials inside the reaction chamber 11.

[0049] refer to Figure 9 and Figure 10 As shown, when the reactor is in its initial state, the first telescopic member 19 is in a retracted state, and the outer surface of the gear 22 meshes with the top of the rack 21;

[0050] Before the staff puts the material into the protective ring 191, the support ring 18 can be moved downward by the multi-section electric push rod 17. When the support ring 18 moves downward, it will drive the gear 22 to move simultaneously through the rotating rod 221. At this time, the gear 22 meshes with the rack 21 and moves downward, causing the gear 22 to rotate counterclockwise. When the gear 22 rotates, it will drive the rotating rod 221 to rotate simultaneously. As the rotating rod 221 rotates counterclockwise, it will cause the pull rope 25 to gradually disengage from the outer surface of the rotating rod 221. At this time, the first telescopic member 19 will drive the bottom end of the pull rope 25 to move downward through the protective ring 191, thereby increasing the internal volume of the protective ring 191. When the support ring 18 moves downward, it will drive the indicator 24 to move simultaneously. When the indicator 24 moves downward, it can point to the scale on the front side of the measuring member 23. Knowing the accurate volume inside the protective ring 191 allows workers to add raw materials into it according to the scale on the measuring piece 23. This enables workers to more accurately judge the amount of raw materials to be added, thus avoiding over- or under-addition. After the raw materials are added, the output end of the multi-section electric push rod 17 drives the support ring 18 to move downwards. The support ring 18 then drives the protective ring 191 downwards via the first telescopic piece 19. The protective ring 191 can then move the raw materials to the bottom of the reaction chamber 11 via the feeding piece 110. This allows the protective ring 191 to load more raw materials into the reaction chamber 11 at once, reducing the frequency and time of feeding, improving production efficiency, and helping to reduce the time difference in batch feeding, resulting in more stable quality of the raw materials after reaction.

[0051] refer to Figures 11 to 13 As shown, when the protective ring 191 moves downward, it can drive the push rod 301 to move simultaneously through the second telescopic member 3. When the push rod 301 moves downward, it will drive the buffer member 33 to move simultaneously through the fixing member 31. When the raw material is put into the interior of the protective ring 191, the raw material will move downward along the upper surface of the buffer member 33. When the raw material falls into the upper surface of the buffer member 33, it can buffer the raw material and cause the buffer member 33 to flip downward. When the buffer member 33 flips downward, it will cause the torsion spring 32 to rotate into a stored state. When the raw material slides down from the upper surface of the buffer member 33, the torsion spring 32 in the stored state will drive the buffer member 33 to reset and flip. At this time, the raw material can also slowly fall into the bottom of the feeder 110, reducing the intensity of the collision between the raw material and the interior of the feeder 110.

[0052] refer to Figures 14 to 16As shown, before the raw material is put into the support ring 18, the winding device 4 is started. The winding device 4 will cause the retracting rope 41 to be in a relaxed state. At this time, the compressed storage spring 42 will drive the push rod 301 to move outward. When the push rod 301 moves, it will drive the output end of the second telescopic member 3 to move at the same time. When the output end of the second telescopic member 3 moves outward, it can cause the push rod 301 to move outward smoothly. When the push rod 301 moves outward, it will drive the buffer member 33 to move outward through the fixing member 31, causing the inner side of the buffer member 33 to completely separate from the inner side of the protective ring 191. Thus, when the raw material is put into the inner side of the protective ring 191, it will not be blocked by the buffer member 33, so that the raw material can fall accurately into the bottom of the first telescopic member 19 and enter the reaction chamber 11, reducing the time consumed in the delivery process.

[0053] When the raw materials are fed in, the winding device 4 causes the retractor rope 41 to retract inward and return to a taut state. When the winding device 4 retracts inward, it causes the output end of the second telescopic member 3 to retract inward. When the second telescopic member 3 retracts inward, it causes the push rod 301 to move simultaneously. When the push rod 301 moves inward, it causes the storage spring 42 to move, which causes the storage spring 42 to return to a compressed state. When the push rod 301 slides inward, it causes the buffer member 33 to slide simultaneously through the fixing member 31, causing the buffer member 33 to return to the inside of the first telescopic member 19.
