It is an indispensable tool in modern pharmaceutical production.

[0003] Before being mixed in the solution tank, pharmaceutical raw materials are typically crushed. Crushing large pieces into smaller particles increases the dissolution rate in the solvent. To achieve rapid dissolution, raw materials are usually in powder form. However, powdered raw materials may form agglomerates or small spherical structures on the solvent surface during mixing, hindering mixing. Furthermore, in chemical manufacturing, crushing and mixing steps are usually performed using different equipment. Excessive equipment not only increases management and maintenance costs but also occupies a large area, reducing space utilization and burdening chemical manufacturers.

[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1-5 As shown in the figure, an online monitoring chemical dosing device according to one embodiment of the present invention includes a solution tank 1. The solution tank 1 is provided with a feed pipe. Various monitoring components, such as weight monitors and mass monitors, are installed at the end of the feed pipe away from the solution tank 1. Through these monitoring components, the raw materials of the medicine can be accurately delivered to the solution tank 1 through the feed pipe to realize online monitoring dosing. The monitoring components work with the feed pipe to achieve accurate dosing. This is a conventional setup and will not be described in detail here.

[0028] like Figures 1-5 As shown, the solution tank 1 includes a chopping zone and a mixing zone. A mixing mechanism 2 is installed inside the solution tank 1. The mixing mechanism 2 includes a motor 201, which is fixedly connected to the top of the solution tank 1. A support rod 202 is fixedly connected to the output end of the motor 201. A stirring rod 203 located in the mixing zone and a cutter 4 located in the chopping zone are fixedly connected to the outer wall of the support rod 202. A separating sieve mechanism 5 matching the cutter 4 is installed inside the solution tank 1. A discharge pipe and several feed pipes are connected to the solution tank 1. The online monitoring chemical dosing device sends a set amount of raw material into the solution tank 1 through the feed pipe. After entering the solution tank 1, the raw material falls onto the separating sieve mechanism 5. The motor 201 is started, and the motor 201 drives the stirring rod 203 and the cutter 4 to rotate via the support rod 202. During this process, the cutter 4, located above the separating sieve mechanism 5, pulverizes the raw material. The raw material crushed to the size of the sieve holes passes through the separating sieve mechanism 5 and is mixed with the solution by the stirring rod 203. The smaller particle size of the crushed pharmaceutical raw materials allows them to dissolve in solvents more quickly, which improves production efficiency to some extent.

[0029] like Figure 5 As shown, a crushing mechanism 3 is installed in the mixing zone. The crushing mechanism 3 breaks up the pharmaceutical raw material powder floating on the water surface during stirring, preventing incomplete mixing and ensuring the efficacy of the medicine. The crushing mechanism 3 includes a crushing plate 302 and crushing teeth 305 that match the crushing plate 302. The crushing teeth 305 are fixedly connected to the solution tank 1, and the crushing plate 302 is fixedly connected to the support rod 202. The crushing plate 302 has filter holes 304, and a connecting component that matches the support rod 202 is installed on the crushing plate 302. With the help of the filter holes 304, as the rolling plate 302 rotates with the support rod 202, the agglomerates or small spherical structures gradually adhere to one side of the rolling plate 302. When the rolling plate 302 and the rolling teeth 305 are misaligned, the agglomerates or small spherical structures can be broken up as much as possible, so that the agglomerates or small spherical structures can be dissolved in the solvent as much as possible and mixed evenly with the pharmaceutical raw materials.

[0030] Furthermore, the rolling plate 302 has multiple rolling grooves 303 on one side, which are matched with the rolling teeth 305. During the rotation of the rolling plate 302, the agglomerates or small spherical structures are more concentrated in the rolling grooves 303. When the rolling teeth 305 and the rolling plate 302 crush the agglomerates or small spherical structures, the agglomerates or small spherical structures are not easily swept away from the sides, thus the crushing efficiency of the agglomerates or small spherical structures is higher and the effect is better.

[0031] Specifically, the range of the solvent level is the upper-middle part of the rolling plate 302 when the rolling plate 302 is at its lowest point in the chute 306.

[0032] like Figures 2-3 As shown, a separating and screening mechanism 5 is installed inside the solution tank 1. The separating and screening mechanism 5 includes a first separating plate 501 and a second separating plate 502. Both the first separating plate 501 and the second separating plate 502 have sieve holes. The first separating plate 501 is fixedly connected inside the solution tank 1, and the second separating plate 502 is slidably connected inside the solution tank 1. When the sieve holes on the first separating plate 501 and the second separating plate 502 are completely staggered and there are no gaps, the first separating plate 501 and the second separating plate 502 are used to separate the chopping zone and the mixing zone, allowing the chopping of the raw materials to be added and the mixing of the materials already added to the mixing zone to proceed simultaneously, maximizing the utilization of the motor 201 and the building space. When the sieve holes on the first separating plate 501 and the second separating plate 502 are not completely staggered and there are gaps, the overlapping sieve holes can control the size of the raw materials entering the mixing zone, making the online monitoring chemical dosing device suitable for more application needs.

[0033] For example, when the properties of a pharmaceutical raw material make its dissolution process very rapid, workers can increase the porosity to allow the drug to enter the mixing zone in the form of large particles, reducing energy consumption caused by excessive crushing.

[0034] like Figures 2-4 As shown, a pushing component for pushing crushed pharmaceutical raw materials into the mixing zone is installed on the first partition plate 501. The pushing component includes a scraper 506, which is fixedly connected to the support rod 202. The scraper 506 can push away and pile up the pharmaceutical raw materials that fall onto the first partition plate 501 and block the sieve holes, repeating the crushing process until the pharmaceutical raw materials can smoothly pass through the sieve holes and enter the mixing zone. Multiple bristles 507 are fixedly connected to the bottom of the scraper 506. When the sieve holes are not completely misaligned, the bristles 507 push the powdered medicine in the groove formed by the sieve holes on the first partition plate 501 and the second partition plate 502 into the sieve holes, so that the powdered pharmaceutical raw materials can fall into the mixing zone for mixing, and avoid leaving finer pharmaceutical raw materials on the first partition plate 501, which cannot dissolve in the solvent and cause inaccurate drug ratios.

[0035] like Figure 3 As shown, a movable component for adjusting the position of the second partition plate 502 is installed on the second partition plate 502. The movable component includes a push plate 503 and a through hole 504 that matches the push plate 503. The through hole 504 is formed on the solution tank 1, and the push plate 503 is fixedly connected to the second partition plate 502. The operator pushes and pulls the push plate 503 to control the size of the overlapping area of ​​the sieve holes, that is, the size of the pores.

[0036] like Figure 3 As shown, a support assembly for supporting the second partition plate 502 is installed at the bottom of the second partition plate 502. The support assembly includes several support plates 505, which are matched with the second partition plate 502. The support plates 505 support the second partition plate 502, minimizing the risk of the second partition plate 502 tilting downwards due to insufficient support when the operator needs to control the particle size by misaligning the first partition plate 501 and the second partition plate 502, thus affecting the normal screening process.

[0037] like Figures 4-5As shown, the connecting assembly ensures that the rolling plate 302 can rotate and move up and down simultaneously. When the rolling plate 302 contacts the rolling teeth 305 and moves upward, it can break up agglomerates or small spherical structures. The connecting assembly includes a slider 301, which is fixedly connected to the rolling plate 302. The support rod 202 has a groove 306 that matches the slider 301. A spring 307 for resetting the slider 301 is installed between the groove 306 and the slider 301. One end of the spring 307 is fixedly connected to the slider 301, and the other end of the spring 307 is fixedly connected to one end of the groove 306. Spring 307 causes slider 301 to drive crushing plate 302 to return to the lowest point in groove 306 more quickly, so as to avoid crushing plate 302 not falling to the lowest point when it rotates to contact crushing tooth 305, and the crushing plate 302 and crushing tooth 305 are misaligned for a short distance, which makes the crushing effect of agglomerates or small spherical structures unsatisfactory.

[0038] During use, when the online monitoring chemical dosing device adds different doses of pharmaceutical raw materials into the solution tank for mixing, it pushes the push plate 503 to form appropriately sized pores on the sieve holes of the first partition plate 501 and the second partition plate 502, thus activating the mixing mechanism 2. The mixing mechanism 2 drives the cutter 4 to rotate and crush the pharmaceutical raw materials. Raw materials that meet the standards enter the mixing zone through the pores, while those that do not meet the standards continue to be crushed. At the same time, the mixing mechanism 2 drives the stirring rod 203 to stir and mix the raw materials, thus achieving the simultaneous crushing and uniform mixing of the raw materials. This improves production efficiency to a certain extent and is beneficial to the crushing efficiency of pharmaceutical raw materials and the smoothness of the overall production process.

[0039] When the powdered pharmaceutical raw materials form agglomerates or small spherical structures that float on the water surface during the mixing process, the crushing mechanism 3 crushes the agglomerates or small spherical structures to minimize the possibility of insufficient mixing of pharmaceutical raw materials, which could affect the efficacy of the drug.

[0040] During the process of mixing the raw materials evenly in the mixing zone, the pusher plate 503 is pushed until the pores are completely closed. Then, the online monitoring chemical dosing device puts the raw materials to be mixed into the solution tank. At this time, the cutter 4 breaks the raw materials to avoid the cutter 4 running idle as much as possible and causing waste of resources.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
