Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical equipment, and particularly to a reaction tank for the intelligent production of sodium amoxicillin. Background Art

[0002] The reaction tank for the intelligent production of sodium amoxicillin is a device that integrates advanced control technology and intelligent manufacturing concepts. Through high-precision sensors and intelligent control systems, it realizes real-time monitoring and precise control of key parameters such as temperature, pressure, flow rate, and pH value during the production process of sodium amoxicillin. Through intelligent algorithms, the reaction tank can automatically adjust various parameters to ensure the stability of the production process and the consistency of product quality. The intelligent system realizes early warning and emergency handling of potential risks, reducing the probability of production accidents.

[0003] Traditional reaction tanks are widely used in the production field. However, due to the limitations of their structures and working principles, there are often some problems that cannot be ignored. For example, traditional reaction tanks mostly use the method of heating or cooling on the outer wall of the tank for temperature control. This method is prone to uneven temperature distribution inside the tank. Due to the difference in the thermal conductivity of the tank body material and the loss of heat during the heat transfer process, the temperature difference between the tank wall and the central area is relatively large, forming a temperature gradient. This uneven temperature control not only affects the uniformity and efficiency of chemical reactions but also may lead to unstable product quality. Especially when producing temperature-sensitive drugs such as sodium amoxicillin, inaccurate temperature control will directly affect the purity and yield of the product. In addition, sodium amoxicillin is prone to form crystals on the stirring components during the production process. These crystals will adhere to the stirring paddles and baffles. This not only reduces the stirring efficiency and increases the difficulty of cleaning and maintenance, but the problem of crystal adhesion also poses higher requirements for the design of the stirring system of the reaction tank. Effective measures need to be taken, such as improving the design of the stirrer, reducing the cleaning difficulty, and ensuring the continuity of production and product quality. Summary of the Invention

[0019] To make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings of the specification.

[0020] Example 1, referring to Figures 1-14, which is the first embodiment of the present invention, provides a reaction tank for the intelligent production of sodium amoxicillin, including a housing 1, further including a stirring mechanism 2 installed on the top of the housing 1, and a switching mechanism 3 installed on the top of the stirring mechanism 2; the stirring mechanism 2 is used for mixing raw materials, and the switching mechanism 3 is used for cleaning the crystals adhering to the stirring mechanism 2; the stirring mechanism 2 includes a driving unit assembled on the top of the housing 1 to provide power, a rotating shaft 21 rotatably connected to the bottom of the driving unit, a rotating arm 22 fixedly connected to the middle of the rotating shaft 21, several vertical rods 23 fixedly connected in a linear array to the bottom of the rotating arm 22, the rotating arm 22 and the cross bar 29 can rotate synchronously with the rotating shaft 21, a lifting block 24 slidably connected to the outside of the rotating shaft 21, a convex block 25 fixedly connected to the side of the lifting block 24 close to the rotating arm 22, the convex block 25 can lift together with the lifting block 24, two guiding rods 26 symmetrically fixedly connected to both sides of the lifting block 24, a slider 27 slidably connected to the side of the guiding rod 26 close to the convex block 25, the front part of the slider 27 is symmetrically provided with sliding holes 28, the inner wall of the sliding holes 28 is slidably connected to the guiding rod 26, the slider 27 can move horizontally along the guiding rod 26, a cross bar 29 fixedly connected to the side of the slider 27 away from the moving block, several magnets 210 fixedly connected in a linear array inside the cross bar 29, several semi-circular grooves 211 penetratingly opened on the top of the cross bar 29, and a heat exchange unit assembled on the top of the rotating shaft 21 for temperature adjustment.

[0021] Specifically, the rotating shaft 21 can transmit power and provide a fixed point for the rotating arm 22. The rotating arm 22 can be linked with the vertical rod 23 to stir the raw materials in the tank and make them evenly mixed. The lifting block 24 can move up and down along the reciprocating lead screw 216, so as to transmit the force from the reciprocating lead screw 216. The convex block 25 can fix the guiding rod 26, and the guiding rod 26 can restrict the movement track and direction of the slider 27. The cross bar 29 can clean the crystals adhering to the vertical rod 23 through the semi-circular grooves 211. Through the action of the same-sex attraction of the magnets 210, the two cross bars 29 can fit together. The stirring mechanism 2 integrates the temperature control component and the stirring component, realizing synchronous temperature control during the stirring process. This integrated design enables the heat to be evenly distributed when the raw materials are stirred, thereby improving the uniformity and stability of temperature control. The stirring effect not only promotes the flow of materials but also helps the heat transfer to all corners of the tank, avoiding local temperature differences. The integrated function of temperature control and stirring simplifies the operation process, improves the reaction efficiency. At the same time, the uniform temperature control environment helps to ensure the product quality, especially in chemical reactions sensitive to temperature. This design is particularly important. Therefore, the synchronous progress of stirring and temperature control provides more stable production conditions for the raw materials.

[0022] Refer to Figure 5 , the cross section of the cross bar 29 is in the shape of an inverted right triangle, and the cross bars 29 corresponding to the two sliders 27 are symmetrical to each other.

[0023] Specifically, the inverted triangular shape of the cross bar 29 enables the liquid raw materials adhering to its surface to drip downward. After the two symmetrical cross bars 29 are fitted under the action of the magnet 210, any two adjacent semi-circular grooves 211 can form a complete circle, so as to surround the outer wall of the vertical bar 23 and clean the crystals adhering to the vertical bar 23 during the up-and-down movement.

[0024] Refer to Figures 6-10 , the driving unit includes a housing 212 fixedly connected to the top of the outer shell 1, a motor 213 fixedly connected to the top of the housing 212, the output shaft at the bottom of the motor 213 is rotatably connected to the rotating shaft 21, a special-shaped hole 214 opened at the bottom of the rotating shaft 21, a limiting ring 215 fixedly connected to the bottom of the rotating shaft 21, a reciprocating lead screw 216 rotatably connected to the inner side of the special-shaped hole 214, a circular hole 217 opened at the top of the lifting block 24, the inner wall of the circular hole 217 is slidably connected to the outer side of the reciprocating lead screw 216, a support shaft 218 fixedly connected to the inner wall of the circular hole 217, and a short pin 219 rotatably connected to the outer side of the support shaft 218, and the outer side of the short pin 219 is threadedly slidably connected to the reciprocating lead screw 216.

[0025] Specifically, the housing 212 can provide support for the motor 213 and other components. The motor 213 can rotate the rotating shaft 21. The rotating shaft 21 accommodates the reciprocating lead screw 216 through the special-shaped hole 214. The limiting ring 215 can restrain the bottom end of the reciprocating lead screw 216 to prevent it from swinging. During the rotation of the reciprocating lead screw 216, it can drive the lifting block 24 to move up and down through the short pin 219 and the support shaft 218. The short pin 219 and the support shaft 218 can transmit the power of the reciprocating lead screw 216. The driving unit can provide power for stirring and cleaning the reaction tank to ensure the normal operation of the equipment. The function of the driving unit is that when stirring is required, it can drive the stirring mechanism 2 to work, so that the raw materials in the tank are fully mixed and the reaction is kept uniform. At the same time, when cleaning the crystals, the driving unit also provides the necessary power to ensure that the crystals are effectively removed. In this way, the reaction tank can obtain power support in both key links of stirring and cleaning, maintaining the continuity of the production process. The configuration of the driving unit makes the operation of the reaction tank more convenient, improves the automation degree of the equipment, and creates conditions for stable production.

[0026] Refer to Figure 7 , a through hole is opened at the top of the limiting ring 215, and the inner wall of the through hole is rotatably connected to the bottom of the reciprocating lead screw 216.

[0027] Specifically, the limiting ring 215 cooperates with the reciprocating lead screw 216 through the through hole at the top to increase the movement stability of the reciprocating lead screw 216.

[0028] Refer to Figures 4-10, the heat exchange unit includes an annular groove 220 fixedly connected to the top of the rotating shaft 21, a slip ring 221 slidably connected to the inside of the chute, two water pipes 222 fixedly connected to the bottom of the housing 212 in parallel, and a flow channel 223 opened on the rotating shaft 21 near the rotating arm 22. The flow channel 223 sequentially penetrates the rotating arm 22 and the vertical rod 23.

[0029] Specifically, the annular groove 220 can cooperate with the slip ring 221 to form a cavity inside to accommodate the heat exchange medium. The two water pipes 222 can accommodate the heat exchange medium to enter and exit. The flow channel 223 can guide the flow trajectory of the heat exchange medium so that it flows through each vertical rod 23.

[0030] Refer to Figure 10 Both ends of the flow channel 223 are respectively connected to the top and bottom of the annular groove 220, and the two water pipes 222 are respectively connected to the two slip rings 221.

[0031] Specifically, after both ends of the flow channel 223 are connected to the top and bottom of the slip ring 221, the heat exchange medium can form a circulation loop.

[0032] Embodiment 2, refer to Figures 1-14 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the switching mechanism 3 includes a collar 31 meshingly connected to the top of the housing 212, handles 32 symmetrically fixedly connected to both sides of the collar 31, a connecting ring 33 rotatably connected to the bottom of the collar 31, a toothed ring 34 fixedly connected to the inside of the connecting ring 33, an intermediate wheel 35 meshingly connected to the inside of the toothed ring 34, the top and bottom of the intermediate wheel 35 are rotatably connected to the top of the special-shaped hole 214, and a driven wheel 36 fixedly connected to the top of the reciprocating lead screw 216.

[0033] Specifically, the rotation direction of the collar 31 can be controlled by the handle 32. The collar 31 can drive the connecting ring 33 at the bottom to move together. The connecting ring 33 can control the height of the toothed ring 34. After the toothed ring 34 generates relative movement with the intermediate wheel 35, the intermediate wheel 35 can be rotated. The intermediate wheel 35 can drive the reciprocating lead screw 216 to rotate. After the switching mechanism 3 is set, the reaction tank can turn on or off the function of cleaning crystals as needed, enhancing the flexibility of equipment use. When cleaning is not required, the normal production process can be maintained, avoiding unnecessary operation interruptions. When crystals accumulate to a certain extent, it can be quickly switched to the cleaning mode to ensure the continuity and efficiency of production. This design enables the reaction tank to adapt to the needs of different production stages, reduces the downtime caused by crystal adhesion problems. At the same time, the flexible switching function also simplifies the operation process, improves the comprehensive utilization rate of the equipment, and provides convenience for production management.

[0034] Refer to Figures 11-14 , the collar 31 is threadedly connected to the housing 212.

[0035] Specifically, after the collar 31 rotates, it can move up and down under the action of the thread, and the rest of the structure is the same as that of Embodiment 1.

[0036] Combined with Embodiments 1-2, the working principle of the present invention is as follows: After putting the raw materials into the reaction tank, start the motor 213. The motor 213 drives the rotating shaft 21 to rotate. While the rotating shaft 21 rotates, it drives the rotating arm 22 and the reciprocating lead screw 216 to rotate synchronously. While the rotating arm 22 rotates, it drives the vertical rod 23 to rotate together. The vertical rod 23 stirs the raw materials in the tank through its own rotation to make them evenly mixed. When it is necessary to control the temperature of the raw materials in the tank, connect the water pipe 222 at the highest position to the water flow with a suitable temperature. The water flow enters the interior of the upper slip ring 221 through the water pipe 222, and enters the rotating shaft 21 through the top of the flow channel 223. The water flow passes through the flow channel 223 and successively passes through the rotating shaft 21, the rotating arm 22 and the vertical pipe, then flows back to the rotating shaft 21, and enters the interior of the lower slip ring 221, and finally flows out through the water pipe 222 at a lower position. During the process that the water flow passes through the vertical rod 23, heat is exchanged between the vertical rod 23 and the raw materials, so as to realize the temperature control of the raw materials. And because the vertical rod 23 stirs while the heat exchange unit controls the temperature of the sodium amoxicillin raw materials, the sodium amoxicillin raw materials are usually in a liquid state. After being heat-exchanged, the raw materials will immediately be mixed with the raw materials at other positions, so as to avoid the temperature difference of the raw materials at different positions affecting the production efficiency and quality. During the production of sodium amoxicillin, if its crystals adhere to the outer surface of the vertical rod 23, which affects the crystallization quality during the production process, the sleeve ring 31 can be rotated by the handle 32. While the sleeve ring 31 rotates, it can move up and down under the action of the thread, and while the sleeve ring 31 moves, it can drive the connecting ring 33 to move together. The connecting ring 33 can only move up and down, and while moving, it drives the gear ring 34 to move synchronously. After moving the gear ring 34 downward to the maximum stroke, the gear ring 34 will be at the same height as the intermediate wheel 35 and mesh with the intermediate wheel 35. While the rotating shaft 21 rotates, it will drive the intermediate wheel 35 to revolve around its own axis. When the intermediate wheel 35 revolves, it moves relative to the gear ring 34. Therefore, the intermediate wheel 35 rotates under the action of the gear ring 34 and drives the driven wheel 36 to rotate while rotating. The driven wheel 36 drives the reciprocating lead screw 216 to rotate. While the reciprocating lead screw 216 rotates, it pushes the short pin 219 to move through the extrusion of its own thread. The short pin 219 drives the lifting block 24 to move synchronously through the support shaft 218. After the lifting block 24 is stressed, it will move up and down reciprocally under the action of the reciprocating lead screw 216. While the lifting block 24 moves, it drives the convex block 25 and the guide rod 26 to displace synchronously. The guide rod 26 drives the corresponding slider 27 and the cross bar 29 to move. Under the action of the magnet 210, the two cross bars 29 will remain in a fitting state. When the cross bar 29 moves downward, its bottom will be extruded by the rotating arm 22 and move in a direction away from the cross arm, so that the two cross bars 29 are separated. When the cross bar 29 moves downward until it does not contact the rotating arm 22, the two cross bars 29 will fit again, and after fitting, the corresponding semi-circular grooves 211 will wrap the corresponding vertical rod 23 again. As the cross bar 29 continues to move downward,The crystallization adhering to the vertical rod 23 will be scraped off. After rotating the collar 31 to move the toothed ring 34 upward and disengage it from the intermediate wheel 35, the reciprocating lead screw 216 will stop rotating, thereby closing the function of cleaning the crystallization.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
