Description

Technical Field

[0001] The invention relates to the technical field of pharmaceutical intermediate preparation, in particular to a standby automatic feeding device for pharmaceutical intermediate preparation. Background Art

[0002] Pharmaceutical intermediates refer to a kind of fine chemical products used to produce APIs or drugs in the process of pharmaceutical synthesis. These compounds play a bridging role in pharmaceutical manufacturing, connecting basic chemical raw materials and final drugs. They are not used directly as drugs themselves, but as key starting materials or products of intermediate steps in the synthesis of drugs. Pharmaceutical intermediates usually have specific chemical structures and properties, which can meet specific needs in drug synthesis. In the process of pharmaceutical production, intermediates undergo a series of chemical reactions, such as addition, substitution, oxidation, reduction, etc., and are gradually converted into target drugs. In the precise preparation process of pharmaceutical intermediates, continuously adding materials to the reactor is a crucial link. However, if solid or liquid materials are accidentally introduced into the reactor at too fast a speed, a series of adverse consequences will be caused. When solid or liquid materials are accidentally added to the reactor at too fast a speed, they will quickly occupy the space in the reaction system and break the original liquid equilibrium state. This sudden impact force will cause violent stirring of the liquid, the so-called "agitation". The agitated liquid will not only make the reaction system unstable, but also accelerate the rate of certain chemical reactions, causing the reaction process to get out of control. For this reason, we propose a backup automatic feeding device for pharmaceutical intermediates. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a standby automatic feeding device for a pharmaceutical intermediate system, comprising a reaction kettle 1, a stirring rod 2 and a feeding pipe 3, wherein the feeding pipe 3 is externally connected to a material supply device, and further comprising a feeding pipe 4, wherein the feeding pipe 4 is arranged on the reaction kettle 1, and the feeding pipe 4 is provided with a plurality of feeding pipes, and a quantitative material is fed into the reaction kettle 1 by using the feeding pipe 4;

[0031] The feeding assembly 5 is arranged on the reactor 1 , and is used to control the rotation of the feeding pipe 4 to feed a certain amount of material in the feeding pipe 4 into the reactor 1 .

[0032] The advantage of the feeding component 5 is that it can automatically feed quantitatively according to the number of stirring times. Automatic quantitative feeding can reduce the frequency and time of manual operation, thereby speeding up production. Accurate feeding control helps to maintain the continuity and stability of the stirring process and improve overall production efficiency. Quantitative feeding can ensure that the material ratio is consistent during each stirring process, thereby stabilizing product quality. The automated feeding system reduces errors caused by human factors and improves product reliability and consistency.

[0033] The buffer deceleration component 9 is arranged on the reactor 1. When the feeding pipe 4 feeds materials into the reactor 1, the buffer deceleration component 9 sprays gas to form a recoil airflow in the reactor 1, thereby slowing down the falling speed of the materials.

[0034] The benefit of the buffer deceleration component 9 is that it can decelerate the material falling into the reactor 1 by airflow recoil, thereby avoiding the material from falling into the liquid and causing agitation. When solid or liquid materials are added to the reactor 1 too quickly, it is easy to cause liquid agitation, resulting in instability of the reaction system. The recoil airflow design can effectively slow down the falling speed of the material, thereby avoiding or reducing this agitation phenomenon, so that the reaction system remains in a relatively stable state. At the same time, too fast addition of materials may cause uneven distribution of reactants in the reactor 1, forming areas with local concentrations that are too high or too low. By slowing down the falling speed of the material by recoil airflow, it is possible to ensure that the reactants are evenly distributed in the reactor 1, improve the uniformity and efficiency of the reaction, and the stability of the reaction system and the uniform distribution of the reactants are crucial to the quality of pharmaceutical intermediates. By slowing down the falling speed of the material, the reaction conditions can be optimized, the generation of side reactions and impurities can be reduced, and the purity and yield of the product can be improved.

[0035] The feeding assembly 5 includes a conveying member 6 arranged on the reactor 1, and the conveying member 6 is used to control the feeding pipe 4 to feed materials into the reactor 1. The reactor 1 is provided with a feeding member 7, and the feeding member 7 is used to control the operation of the conveying member 6. The reactor 1 is provided with a driving member 8, and the driving member 8 is used to provide power for the operation of the feeding member 7.

[0036] The conveying member 6 includes a storage bin 61 arranged on the reactor 1, the storage bin 61 is connected to the feed pipe 3, a distribution bin 62 is arranged in the storage bin 61, a rotating plate 63 is rotatably arranged in the distribution bin 62, the rotating plate 63 is connected to the feeding pipe 4, and the feeding pipe 4 is slidably connected to the distribution bin 62.

[0037] The delivery member 7 includes a rotating groove 71 opened on the material distribution bin 62, a rotating plate 63 is provided with a rotating tooth 72, and the rotating tooth 72 is slidably connected with the rotating groove 71. A positioning shaft 73 is rotatably provided on the reactor 1, and a rotating gear 74 is provided on the positioning shaft 73.

[0038] The advantage of the arrangement of the conveying member 6 and the dispensing member 7 is that a quantitative amount of material can be automatically dispensed into the reactor 1 when preparing pharmaceutical intermediates. The quantitative automatic dispensing system can accurately control the amount of material dispensed to ensure that the amount of material required for each reaction is consistent, thereby reducing the frequency and time of manual operations and improving production efficiency. At the same time, the automated dispensing process reduces the errors caused by human factors, making the production process smoother and helping to improve the efficiency of the overall production line.

[0039] The driving member 8 includes a fixed plate 81 arranged on the reactor 1, a sliding rod 82 is slidably arranged on the fixed plate 81, a limiting plate 83 is arranged on the sliding rod 82, a return spring 84 is sleeved on the sliding rod 82 between the fixed plate 81 and the limiting plate 83, a pushing rod 85 is arranged on the end of the sliding rod 82 away from the limiting plate 83, a driving shaft 86 is arranged on the rotating gear 74, the driving shaft 86 is connected to the rotating gear 74 through a one-way bearing, a pushing groove 87 is opened on the driving shaft 86, and the pushing groove 87 is slidably connected to the pushing rod 85.

[0040] When the sliding rod 82 rises and drives the pushing rod 85 to rise, the pushing rod 85 slides synchronously in the pushing groove 87, thereby driving the driving shaft 86 to rotate. The rotation of the driving shaft 86 drives the rotating gear 74 connected thereto to rotate. At the same time, because the driving shaft 86 is connected to the rotating gear 74 through a one-way bearing, when the pushing rod 85 is reset and drives the driving shaft 86 to rotate in the opposite direction, it will not drive the rotating gear 74 to rotate synchronously. When the rotating gear 74 rotates, it drives the rotating tooth 72 engaged therewith to rotate synchronously. The rotation of the rotating tooth 72 drives the rotating plate 63 to rotate. The rotation of the rotating plate 63 drives the feeding pipe 4 to rotate, so as to feed a certain amount of material into the reactor 1.

[0041] The buffer deceleration component 9 includes a jet component 10 arranged on the reactor 1, through which gas is sprayed into the reactor 1. The reactor 1 is provided with a circulation component 11, through which the circulation component 11 controls the circulation of the jet component 10. The reactor 1 is provided with a power component 12, which is used to provide power for the circulation component 11.

[0042] The jet component 10 includes a plurality of connecting tubes 101 arranged on the reactor 1, one end of the sliding rod 82 extends into the connecting tube 101 and is slidably connected to the connecting tube 101, the connecting tube 101 is connected to the inside of the reactor 1, a pneumatic tube 102 is arranged on the connecting tube 101, a piston plate 103 is slidably arranged in the pneumatic tube 102, a power spring 104 is arranged on the piston plate 103, one end of the power spring 104 is connected to the pneumatic tube 102, a diffuser plate 105 is arranged at one end opening of the connecting tube 101 located in the reactor 1, a one-way air outlet valve 106 is arranged on one side of the diffuser plate 105 in the connecting tube 101, and a one-way air inlet valve 107 is arranged on the connecting tube 101.

[0043] The benefit of the jet part 10 is that it can decelerate the material falling into the reactor 1 by the airflow recoil, thereby avoiding the material from falling into the liquid and causing agitation. When solid or liquid materials are added to the reactor 1 too quickly, it is easy to cause liquid agitation, resulting in instability of the reaction system. The recoil airflow design can effectively slow down the falling speed of the material, thereby avoiding or reducing this agitation phenomenon, so that the reaction system remains in a relatively stable state. At the same time, adding materials too quickly may cause uneven distribution of reactants in the reactor 1, forming areas with excessively high or low local concentrations. Slowing down the falling speed of the material by the recoil airflow can ensure that the reactants are evenly distributed in the reactor 1, improving the uniformity and efficiency of the reaction.

[0044] The circulation member 11 comprises an annular plate 111 rotatably arranged on the reactor 1, a plurality of circulation plates 112 are arranged on the annular plate 111, and a circulation tooth groove 113 is opened on the circulation plate 112. A circulation shaft 114 is rotatably arranged on the reactor 1, and a circulation gear 115 engaged with the circulation tooth groove 113 is arranged on the circulation shaft 114. A support plate 116 is arranged on the reactor 1, and the support plate 116 is L-shaped and rotatably connected to the circulation shaft 114. 16 is provided with a clockwork box 117, the circulating shaft 114 penetrates the clockwork box 117 and is rotatably connected to the clockwork box 117, a clockwork spring 118 is provided in the clockwork box 117, one end of the clockwork spring 118 is connected to the circulating shaft 114, a winding wheel 119 is provided on the circulating shaft 114, a traction rope 1110 is provided on the winding wheel 119, the traction rope 1110 penetrates the pneumatic tube 102 and is connected to the piston plate 103, and the traction rope 1110 is movably connected to the pneumatic tube 102.

[0045] The advantage of the circulation part 11 is that the rotation of the stirring rod 2 can be used to drive the jet part 10. This design can save an additional power source, thereby simplifying the equipment structure, reducing equipment complexity and manufacturing costs. At the same time, the rotation speed of the stirring rod 2 is used to regulate the jet volume, so that more precise jet control can be achieved. This is particularly important for the preparation process of pharmaceutical intermediates that requires precise control of reaction conditions and avoids excessive or insufficient jetting. Secondly, the synergistic effect of stirring and jetting helps to speed up the reaction rate and improve the reaction efficiency. At the same time, uniform material mixing and precise jet control help to obtain higher quality and more stable pharmaceutical intermediate products.

[0046] The power member 12 includes a power plate 121 arranged on the reactor 1, a power shaft 122 is rotatably arranged on the power plate 121, a power pulley 123 is arranged on the power shaft 122 and the stirring rod 2, a power belt 124 is arranged on the power pulley 123, a power gear 125 is arranged on the end of the power shaft 122 away from the power pulley 123, and a power latch 126 engaged with the power gear 125 is arranged on the annular plate 111.

[0047] When the stirring rod 2 rotates, the power shaft 122 is driven to rotate through the power pulley 123 and the power belt 124. The rotation of the power shaft 122 drives the power gear 125 arranged thereon to rotate. The rotation of the power gear 125 drives the power latch 126 engaged with it to rotate. The rotation of the power latch 126 drives the annular plate 111 connected thereto to rotate. The rotation of the annular plate 111 drives the circulation plate 112 arranged thereon and the circulation tooth groove 113 opened on the circulation plate 112 to rotate. The circulation tooth groove 113 engages with the circulation gear 115 during the rotation process, thereby driving the circulation gear 115 to rotate. The rotation of the circulation gear 115 drives the circulation shaft 114 to rotate. At this time, the clockwork spring 118 accumulates force, and when the circulation shaft 114 rotates, it will synchronously drive the winding wheel 119 to rotate, thereby driving the traction rope 1110 to be wound up, further driving the piston plate 103 to move in the pneumatic tube 102.

[0048] At this time, the circulation plate 112 continues to rotate until the circulation tooth groove 113 is disengaged from the circulation gear 115. At this time, the circulation gear 115 and the circulation shaft 114 are driven by the clockwork spring 118 to rotate in the opposite direction, and drive the winding wheel 119 to rotate in the opposite direction, so that the traction rope 1110 is released. When the traction rope 1110 is released, the limit on the piston plate 103 is released. At this time, the piston plate 103 moves in the pneumatic tube 102 under the push of the power spring 104 and synchronously compresses the gas in the pneumatic tube 102, and sends the gas in the pneumatic tube 102 into the reactor 1 through the one-way air outlet valve 106 and the diffuser plate 105. When the gas contacts the liquid surface in the reactor 1, a recoil is formed to cushion the falling material. When the piston plate 103 rises to the highest point, it contacts the sliding rod 82 extending into the connecting pipe 101 and pushes the sliding rod 82 to rise.

[0049] When in use, first start the stirring rod 2 in the reactor 1. When the stirring rod 2 rotates, the power shaft 122 is driven to rotate through the power pulley 123 and the power belt 124. The power shaft 122 rotates to drive the power gear 125 arranged thereon to rotate. The power gear 125 rotates to drive the power latch 126 engaged with it to rotate. The power latch 126 rotates to drive the annular plate 111 connected thereto to rotate. The annular plate 111 rotates to drive the circulation plate 112 arranged thereon and the circulation tooth groove 113 opened on the circulation plate 112 to rotate. The circulation tooth groove 113 engages with the circulation gear 115 during the rotation process, thereby driving the circulation gear 115 to rotate. The circulation gear 115 rotates to drive the circulation shaft 114 to rotate. At this time, the clockwork spring 118 accumulates force, and when the circulation shaft 114 rotates, it will synchronously drive the winding wheel 119 to rotate, thereby driving the traction rope 1110 to be wound up and further driving the piston plate 103 to move in the pneumatic tube 102.

[0050] At this time, the circulation plate 112 continues to rotate until the circulation tooth groove 113 is disengaged from the circulation gear 115. At this time, the circulation gear 115 and the circulation shaft 114 are driven by the clockwork spring 118 to rotate in the opposite direction, and drive the winding wheel 119 to rotate in the opposite direction, so that the traction rope 1110 is released. When the traction rope 1110 is released, the limit on the piston plate 103 is released. At this time, the piston plate 103 moves in the pneumatic tube 102 under the push of the power spring 104 and synchronously compresses the gas in the pneumatic tube 102, and sends the gas in the pneumatic tube 102 into the reactor 1 through the one-way air outlet valve 106 and the diffuser plate 105. When the gas contacts the liquid surface in the reactor 1, a recoil is formed to cushion the falling material. When the piston plate 103 rises to the highest point, it contacts the sliding rod 82 extending into the connecting pipe 101 and pushes the sliding rod 82 to rise.

[0051] When the sliding rod 82 rises and drives the pushing rod 85 to rise, the pushing rod 85 slides synchronously in the pushing groove 87, thereby driving the driving shaft 86 to rotate. The rotation of the driving shaft 86 drives the rotating gear 74 connected thereto to rotate. At the same time, because the driving shaft 86 is connected to the rotating gear 74 through a one-way bearing, when the pushing rod 85 is reset and drives the driving shaft 86 to rotate in the opposite direction, it will not drive the rotating gear 74 to rotate synchronously. When the rotating gear 74 rotates, it drives the rotating tooth 72 engaged therewith to rotate synchronously. The rotation of the rotating tooth 72 drives the rotating plate 63 to rotate. The rotation of the rotating plate 63 drives the feeding pipe 4 to rotate, so as to feed a certain amount of material into the reactor 1.

[0052] Example 2: Please refer to Fig. 9 The present invention provides a technical solution: the traction rope 1110 is made of polyester fiber. The traction rope 1110 made of polyester fiber has the characteristics of high strength, light weight, corrosion resistance, and not easy to break, which can greatly extend the service life.
