After opening, water flows through the first telescopic hose 22 into the drain pipe 23. When the second dissolving barrel 1 shakes, the first telescopic hose 22 and the second telescopic hose 24 extend and bend along with the second dissolving barrel 1, and water flows through the drain pipe 23 and is discharged from the end of the second telescopic hose 24.

Appropriate temperature control can keep the drug stable during the dissolution process, thereby increasing the effect of drug dissolution and effectively reducing the problem of drug precipitation or crystallization, thereby improving the quality and stability of drug dissolution.

[0025] like Figure 2 、 Figure 3 、 Figure 5As shown, the side wall of the second dissolving barrel 1 is provided with two chutes 3; a slider 31 is slidably connected to the middle of the chutes 3; the ends of the two sliders 31 are fixedly connected to a connecting rod 32; a scraper 33 is fixedly connected to the middle of the connecting rod 32; the end of the scraper 33 is in contact with the side wall of the second dissolving barrel 1; a third magnet 34 is fixedly connected to the middle of the connecting rod 32; the third magnet 34 is fixedly connected to the side away from the connecting rod 32; the third magnet 34 is attracted to the first magnet 13 when they are close to each other; during operation, when the first magnet 13 rotates through the first fixed rod 12, one of the first magnets 13 and the third magnet 34 is close to generate suction, so that the third magnet 34 is connected to the first magnet 13, and when the first magnet 13 rotates, it drives the connecting magnet 34 to rotate. The rod 32 rotates at the same time, causing the slider 31 to slide inside the chute 3, and the side wall is cleaned by the end of the scraper 33 fitting against the surface of the second dissolving barrel 1.

[0026] like Figures 2 to 5 As shown, a quantitative plate 4 is fixedly connected to the middle of the first rotating rod 84; the quantitative plate 4 is fixedly connected to the second dissolving barrel 1 near the top; a through hole 41 is opened in the middle of the quantitative plate 4; the through hole 41 is consistent with the diameter of the feed pipe 81; the top of the quantitative plate 4 is in contact with the bottom of the feed pipe 81; during operation, when the first rotating rod 84 rotates, it drives the quantitative plate 4 to rotate. When the through hole 41 coincides with the bottom of the feed pipe 81, the drug raw material enters the second dissolving barrel 1 through the middle of the through hole 41, so that the drug raw material is added in sections. The segmented addition of the drug raw material through the quantitative plate 4 can better control the dissolution rate, maintain a stable concentration of the drug during the dissolution process, effectively carry out subsequent crystal formation and control, effectively reduce the uneven dissolution caused by adding a large amount of drug raw materials at one time, reduce the problem of some raw materials failing to dissolve in time to form lumps or deposits, effectively dissolve the drug raw materials gradually, and effectively improve the uniformity of drug dissolution.

[0027] like Figures 2 to 5As shown, a mesh plate 5 is fixed to the bottom of the quantitative plate 4; the mesh plate 5 is fixed to the position corresponding to the through hole 41; a second fixing rod 51 is fixed to the side wall of the second dissolving barrel 1; a plurality of groups of bristles 52 are fixed to the middle of the second fixing rod 51; during operation, when the drug raw material passes through the through hole 41 and enters the second dissolving barrel 1, it is first filtered through the mesh plate 5. When the quantitative plate 4 rotates, when the bottom of the mesh plate 5 passes through the bristles 52, the bottom of the mesh plate 5 is cleaned by the contact between the end of the bristles 52 and the bottom of the mesh plate 5. The mesh plate 5 can effectively reduce the mixing of various dust and impurities into the drug raw materials, effectively reduce the presence of impurities in the drug raw materials to reduce the solubility and purity of the drugs, increase the purity of the drug raw materials, and effectively reduce the large solid particles or impurities in the drug raw materials directly entering the second dissolving barrel 1, reduce the problem of wear on the second dissolving barrel 1, increase the purity of the drug raw materials, and increase the contact area with the solvent, effectively increase the rapid dissolution of the drug.

During the rotation of the second support rod 6, the blade 62 contacts the bottom of the second dissolving barrel 1 and rotates in the middle of the second support rod 6 through the roller 61. The blade 62 can effectively break the agglomeration state of the drug raw materials, effectively increase the contact area between the drug raw materials and the solvent, and can continuously redisperse the precipitate into the solution during the dissolution of the drug raw materials, effectively reducing the deposition of the drug raw materials at the bottom of the second dissolving barrel 1 or the formation of lumps.

[0029] During operation, the raw materials are put into the second dissolving barrel 1 from the end of the feeding tube 81, and the raw materials are allowed to enter the second dissolving barrel 1. The motor 83 is turned on to rotate the output end, and the first rotating rod 84 is rotated by the motor 83, and the raw materials are stirred by the first stirring blade 85. The dissolved drug raw materials are mixed by the first stirring blade 85, and then the electric push rod 11 is controlled to stretch to make the second dissolving barrel 1 shake, and the spring 10 is used to support it as the second dissolving barrel 1 shakes. In the process of stirring the drug raw materials, the first magnet 13 and the second magnet 18 are close to each other and repel each other, so that the second stirring blade 17 is away from the first magnet 13. The second magnet 18 on the next second stirring blade 17 is moved and brought close to the first magnet 13. The above operation is repeated to rotate the second stirring blade 17 through the rotating shaft 15 to fully stir and mix the dissolved medicinal raw materials.

When the first magnet 13 rotates, the connecting rod 32 is driven to rotate at the same time, so that the slider 31 slides inside the chute 3. The end of the scraper 33 is in contact with the surface of the second dissolving barrel 1 to clean the side wall. When the first rotating rod 84 rotates, it drives the quantitative plate 4 to rotate. When the through hole 41 coincides with the bottom of the feeding pipe 81, the drug raw material passes through the through hole 41. The middle part enters the second dissolving barrel 1, so that the drug raw materials are added in sections. When the drug raw materials enter the second dissolving barrel 1 through the through hole 41, they are first filtered through the mesh plate 5. When the quantitative plate 4 rotates, the bottom of the mesh plate 5 passes through the brush 52, and the bottom of the mesh plate 5 is cleaned by the contact between the end of the brush 52 and the bottom of the mesh plate 5. When the first rotating rod 84 rotates, the second support rod 6 rotates simultaneously with the first rotating rod 84. During the rotation of the second support rod 6, the blade 62 contacts the bottom of the second dissolving barrel 1 and rotates in the middle of the second support rod 6 through the roller 61.
