Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid drug dissolution, and in particular to a solid drug dissolution and dosing device. Background Technology
[0002] The dissolution of solid drugs refers to the process of adding solid drugs to a suitable solvent and then dispersing their molecules or ions uniformly in the solvent to form a homogeneous solution through stirring or ultrasound. The dissolution rate is affected by factors such as drug particle size, solvent properties, and stirring intensity.
[0003] In the process of dissolving solid drugs, due to the different particle sizes of the raw materials, pre-crushing is usually required to improve the dissolution efficiency. However, the crushed drug powder is prone to weighing errors when added, making it difficult to accurately control the amount of material added, which in turn affects the uniformity of the final solution. In addition, if only conventional stirring at room temperature is used, the lack of temperature assistance and insufficient shear force will cause the drug particles to agglomerate or settle, making it difficult for the system to form a uniform and stable solution, which significantly reduces the dissolution effect and mixing quality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a solid drug dissolving and dosing device that divides powder into fixed volumes and adds it evenly, significantly improving the dosing accuracy and effectively breaking the tendency of drug agglomeration and sedimentation.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A solid drug dissolving and dosing device, comprising: The dissolving tank is used for support. A mounting frame is fixedly connected to the top of the dissolving tank. A dispensing tank is fixedly connected to the inner side of the mounting frame. A crushing rod is rotatably connected inside the dispensing tank. Multiple crushing blades are fixedly connected to the outer circumference of the crushing rod. A baffle filter plate is fixedly connected to the lower inner side of the dispensing tank. A feeding frame is fixedly connected to the bottom of the dispensing tank. A uniform feeding component is installed inside the feeding frame to achieve uniform dispensing of solid reagents. A rotating rod is used for internal rotational support of the dissolving tank. Multiple stirring plates are fixedly connected to the outer circumference of the rotating rod. A second motor is fixedly connected to the bottom of the dissolving tank. The drive end of the second motor is fixedly connected to the bottom of the rotating rod. An annular heating assembly is installed inside the dissolving tank to achieve the effect of mixing the medicine.
[0006] Furthermore, the annular heating assembly includes an arc frame fixed at the lower inner side of the dissolving tank, a heating ring tube fixedly connected inside the arc frame, and a cooling ring groove opened on the lower outer side of the dissolving tank.
[0007] Furthermore, the uniform feeding assembly includes a rotating rod that rotates inside the feeding frame, a rotating roller that is fixedly connected to the outside of the rotating rod, a plurality of partition plates that are fixedly connected to the outside of the rotating roller, a first bevel gear that is fixedly connected to the rear side of the outside of the rotating rod, and a second bevel gear that is fixedly connected to the bottom end of the crushing rod, with the second bevel gear meshing with the first bevel gear.
[0008] Furthermore, a first motor is fixedly connected to the top center of the dispensing tank, and the drive end of the first motor is fixedly connected to the top of the crushing rod.
[0009] Furthermore, a downward inclined block is fixedly connected to the lower interior side of the dispensing tank.
[0010] Furthermore, an annular traction block is fixedly connected to the inner side of the dispensing tank, above the blocking filter plate.
[0011] Furthermore, multiple support columns are fixedly connected around the inside of the cooling ring groove.
[0012] This utility model has the following beneficial effects: In this invention, the raw materials are directly crushed in the tank through the mechanical crushing design of the top crushing rod and crushing blades, eliminating the pre-crushing process. The crushed medicine is screened by the blocking filter plate to ensure the uniformity of the particles. The rotating rod and the partition plate in the feeding frame are linked by the first bevel gear and the second bevel gear to crush the powder in a fixed volume and then add it evenly, which significantly improves the feeding accuracy.
[0013] In this invention, the heating ring 15 inside the dissolving tank uniformly heats the drug solution, accelerating molecular diffusion. At the same time, the second motor drives the rotating rod to rotate the stirring plate at high speed, providing strong shear force and effectively breaking the tendency of drug agglomeration and sedimentation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Reference Figure 1-3 This utility model provides an embodiment of a solid drug dissolving and dosing device, comprising a dissolving tank 1 for support, a mounting frame 2 fixedly connected to the top of the dissolving tank 1, a dispensing tank 3 fixedly connected to the inner side of the mounting frame 2, a crushing rod 10 rotatably connected inside the dispensing tank 3, a plurality of crushing blades 11 fixedly connected around the outer circumference of the crushing rod 10, a baffle filter plate 9 fixedly connected to the lower inner side of the dispensing tank 3, and a feeding frame 5 fixedly connected to the bottom of the dispensing tank 3. A uniform dispensing component is installed inside the feeding frame 5 to achieve uniform dispensing of the solid drug. The uniform dispensing component includes a rotating rod 20 located inside the feeding frame 5. (Refer to...) Figure 4 A rotating roller 18 is fixedly connected to the outside of the rotating rod 20. Multiple partition plates 19 are fixedly connected around the outside of the rotating roller 18. A first bevel gear 21 is fixedly connected to the rear side of the rotating rod 20. (Refer to...) Figure 5 The bottom end of the crushing rod 10 is fixedly connected to a second bevel gear 22, which meshes with the first bevel gear 21. The top middle of the feeding tank 3 is fixedly connected to a first motor 4, and the drive end of the first motor 4 is fixedly connected to the top of the crushing rod 10. The lower side of the inside of the feeding tank 3 is fixedly connected to a lower inclined block 8, and the inner side of the feeding tank 3 is fixedly connected to an annular traction inclined block 12 above the blocking filter plate 9. After the solid medicine is put into the feeding tank 3, the first motor 4 at the top drives the crushing rod 10 to rotate, which drives the circumferentially arranged crushing blades 11 to mechanically crush the medicine. After the crushed medicine powder is screened by the blocking filter plate 9, it enters the feeding frame 5 under the guiding action of the annular traction inclined block 12. During this process, the second bevel gear 22 at the bottom of the crushing rod 10 meshes with the first bevel gear 21 on the rotating rod 20, which drives the rotating rod 20 to rotate synchronously. The partition plates 19 evenly distributed on the outer circumference of the rotating rod precisely divide the powder into fixed volumes as it rotates, and finally realizes the uniform quantitative addition of medicine powder to the dissolving tank 1.
[0018] Reference Figure 1 and Figure 2 A rotating rod 13 is used for internal rotational support of the dissolving tank 1. Multiple stirring plates 16 are fixedly connected to the outer circumference of the rotating rod 13. A second motor 17 is fixedly connected to the bottom end of the dissolving tank 1. The drive end of the second motor 17 is fixedly connected to the bottom end of the rotating rod 13. An annular heating assembly is installed on the inner side of the dissolving tank 1 to achieve the effect of mixing the medicine. The annular heating assembly includes an arc frame 14 fixedly located in the lower part of the inner side of the dissolving tank 1. A heating ring tube 15 is fixedly connected inside the arc frame 14. A cooling ring groove 7 is opened on the lower outer side of the dissolving tank 1. Multiple support columns 6 are fixedly connected to the inner circumference of the cooling ring groove 7. During the operation of the dissolving tank, the second motor 17 drives the rotating rod 13 to drive the stirring plate 16 to perform high-speed shearing and mixing of the solution. At the same time, the heating ring pipe 15 uniformly heats the tank to promote the dissolution of the agent. To ensure the accuracy of temperature control, the system adopts an intelligent temperature control design: when the heating ring pipe 15 is working, the cooling ring groove 7 is activated simultaneously, and external cooling air is introduced into the system through forced convection to promptly discharge the high-temperature gas generated by heating. This dynamic temperature control mechanism not only ensures the optimal dissolution temperature, but also effectively prevents overheating, significantly improving the mixing efficiency and operational safety of the device.
[0019] Working principle: After the solid agent is put into the feeding tank 3, the first motor 4 at the top drives the crushing rod 10 to rotate, which drives the circumferential crushing blades 11 to mechanically crush the agent. After being screened by the blocking filter plate 9, the crushed powder is guided to the feeding frame 5 by the annular traction inclined block 12. At this time, the second bevel gear 22 at the bottom of the crushing rod 10 meshes with the first bevel gear 21 on the rotating rod 20, which drives the rotating rod to rotate. This causes the outer partition plate 19 to divide the powder into fixed volumes and add it evenly to the dissolving tank 1. In the dissolving tank, the second motor 17 drives the rotating rod 13 to drive the stirring plate 16 to shear the solution at high speed. At the same time, the heating ring pipe 15 heats the tank body evenly to accelerate dissolution. During the heating process of the heating ring pipe 15, the cooling ring groove 7 allows the external air to enter inward, thereby venting the high temperature generated by the heating ring pipe 15 to a certain extent, avoiding excessive internal temperature and improving the mixing efficiency of the device.
[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
