Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a vertical storage tank for preventing drug precipitation. Background Art

[0002] Drug precipitation is one of the common problems in the pharmaceutical manufacturing process, especially in liquid drug preparations. Drug precipitation not only affects the appearance and uniformity of the drug, but more importantly, it may lead to uneven distribution of the drug's active ingredients, thereby affecting the drug's efficacy and safety.

[0003] In existing pharmaceutical equipment, stirring is mostly used to prevent drug precipitation. Traditional stirring devices may not be able to achieve completely uniform stirring of drugs in the storage tank. That is, when some large-particle drugs fall into the pharmaceutical equipment, they may directly settle at the bottom of the tank due to their slow dissolution rate and large volume. At this time, the accelerating mixing effect of stirring is minimal, resulting in precipitation in local areas. In particular, those drugs that are prone to agglomeration or precipitation are more likely to experience uneven stirring. Utility Model Content

[0022] During specific implementation: solid medicine is put into the shell 1 from the feed port 3, and then the two crushing rollers 6 will preliminarily crush the solid medicine into small pieces. The crushed medicine will fall onto the filter plate 8, and then the electric telescopic rod 14 is started to push the rolling roller 11 to roll on the filter plate 8 for repeated rolling. At the same time, the brush 10 fixed on the fixed frame 9 will clean the medicine powder that may be adsorbed on the rolling roller 11, and the crushed medicine will pass through the filter plate 8 and fall into the interior of the mixing barrel 2. Then the rotating blades 15 inside the mixing barrel 2 will break up the crushed medicine, so that the medicine falls more evenly into the mixing barrel 2 for full dissolution.

[0023] It should be noted that a discharge valve is fixedly provided on the mixing barrel 2 , and the position of the discharge valve is slightly above the partition 17 .

[0024] The two crushing rollers 6 are provided to crush the medicine so that the medicine particles reach a certain fineness, which helps to increase the surface area of ​​the medicine and promote the dissolution of the medicine; the second servo motor 19 is provided to drive the rotating shaft 7 and the crushing roller 6 to operate, and the use time can be manually controlled, opened when in use and closed when not in use, which can save resources and is easy to operate; the discharge valve is provided to facilitate subsequent material collection.

[0025] See Figure 2The rolling assembly is movably arranged in the shell 1, and the rolling assembly includes a fixed frame 9 arranged in the shell 1. A rolling roller 11 is rotatably connected in the fixed frame 9. A brush 10 is fixedly connected to the upper bottom surface of the fixed frame 9. The lower end of the brush 10 is close to the rolling roller 11. A slider 12 is fixedly connected to the outer wall of the fixed frame 9. A slide groove 13 is opened on the inner wall of the shell 1. The slider 12 is slidably inserted in the slide groove 13. An electric telescopic rod 14 is fixedly inserted on the shell 1, and the telescopic end of the electric telescopic rod 14 is fixedly connected to the fixed frame 9.

[0026] The brush 10 is arranged to be in close contact with the crushing roller 11, and can clean the drug powder that may be adsorbed on the surface of the crushing roller 11 when the crushing roller 11 rotates, so that the drug powder can fully fall into the next stage, reducing the waste of drugs; the crushing assembly is slidably connected to the slide groove 13 on the inner wall of the shell 1 through the slider 12, so that the crushing assembly can move flexibly in the shell 1, is not prone to jamming and other phenomena, and maintains operational stability; the electric telescopic rod 14 is arranged to push the crushing roller 11 to achieve all-round crushing of the drugs on the filter plate 8.

[0027] See Figure 3 A first servo motor 18 is fixedly connected to the mixing barrel 2, a partition 17 is fixedly arranged above the first servo motor 18, a driving shaft of the first servo motor 18 is connected to a stirring paddle 16, and a rotating blade 15 is fixedly connected to the upper end of the stirring paddle 16, and the rotating blade 15 is arranged below the filter plate 8.

[0028] The stirring paddle 16 and the rotating blade 15 are driven to rotate by the first servo motor 18 to achieve sufficient stirring and mixing of the medicine in the stirring barrel 2, thereby ensuring the uniformity and efficiency of the stirring process; the rotating blade 15 can be used to disperse the fallen medicine to the surrounding areas through the rotating blade 15, so that it can fall more evenly into the interior of the stirring barrel 2 for full dissolution.

[0029] See Figure 1 The shape of the shell 1 is "L"-shaped, and the rolling assembly is arranged in a protruding cavity in the shell 1.

[0030] The "L"-shaped housing 1 design can more effectively utilize space, and by arranging the rolling assembly in the protruding cavity, further space can be saved, making the overall equipment more compact and convenient for installation and transportation.

[0031] See Figure 2 A top cover 4 is hinged on the feed port 3, and a handle 5 is fixedly connected to one side of the top cover 4. The handle 5 is provided with anti-slip lines.

[0032] The top cover 4 provided can protect the components inside the feed port 3 from pollution and damage from the external environment. When no feeding is required, the top cover 4 can be closed to keep the inside of the equipment clean and hygienic. The anti-slip texture provided on the handle 5 can increase the friction between the user's hand and the handle 5 to prevent slipping or falling out of the hand during operation, which not only improves the safety of operation, but also enables the user to control the opening and closing of the top cover 4 more stably.

[0033] See Figure 1 There are two sliders 12 , and the two sliders 12 are respectively arranged on the two side walls inside the fixing frame 9 .

[0034] The two sliders 12 can form a stable support structure, which helps to balance the load and reduce vibration and shaking caused by eccentricity or asymmetry, thereby improving the stability of the overall structure.

[0035] See Figure 4 A protective shell 20 is provided on the outside of the second servo motor 19. The protective shell 20 is fixedly connected to the outer wall of the housing 1. Heat dissipation holes are evenly arranged in an array on the protective shell 20.

[0036] The protective shell 20 can protect the second servo motor 19 from damage caused by external factors, thereby increasing the service life of the second servo motor 19; the heat dissipation holes evenly arranged in an array on the protective shell 20 can maintain the stable operation of the second servo motor 19 inside the protective shell 20.

[0037] Working principle: When the device is in use, first open the top cover 4, then start the second servo motor 19, and then put the solid medicine into the shell 1 from the feed port 3, and then the two crushing rollers 6 will initially crush the solid medicine into small pieces, and the crushed medicine will fall onto the filter plate 8, and then start the electric telescopic rod 14 to push the rolling roller 11 to slide in the slide 13 through the slider 12 in the shell 1, and then roll on the filter plate 8 for repeated rolling. The brush 10 fixed on the fixed frame 9 will sweep away the medicine powder that may be adsorbed on the rolling roller 11, and the crushed medicine will fall into the interior of the mixing barrel 2 through the filter plate 8, and the stirring paddle 16 in the mixing barrel 2 is in a state of continuous rotation. The rotating blades 15 fixedly connected to the stirring paddle 16 will also rotate together, so that the medicine falling from the filter plate 8 is scattered around by the blades on the rotating blades 15, and can fall into the stirring barrel 2 more evenly for full dissolution. After the medicine is added, the top cover 4 can be manually closed to prevent external impurities from falling into the storage tank. By crushing the medicine and then dissolving it, the contact area between the medicine and the solvent can be increased, making the medicine dissolve more thoroughly, avoiding the chance of the medicine being precipitated at the bottom of the medicine storage tank due to volume or weight, and by breaking up the crushed medicine, the medicine can be more evenly dropped into the solution without accumulation, further reducing the risk of drug precipitation.
