Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical liquid processing technology, specifically a pharmaceutical liquid extraction device. Background Technology

[0002] In the production and processing of medicinal liquids, it is necessary to carry out the extraction process, which requires the use of medicinal liquid extraction equipment. The medicinal liquid extraction equipment is used to extract the effective components from Chinese medicinal materials or other raw materials to make medicinal liquids. This includes maceration extraction equipment, which soaks Chinese medicinal materials in a solvent (such as water or ethanol) to allow the effective components to slowly dissolve into the solvent. After a certain period of time, the extract is separated.

[0003] Existing drug extraction devices still have the following problems when in use: For large impregnation tanks, it is difficult to achieve uniform mixing of medicinal materials and solvents. The medicinal materials at the bottom may have more contact with the solvent, while the medicinal materials at the top may not be impregnated sufficiently, resulting in inconsistent extraction effects. In addition, it is impossible to ensure that the solvent is always in a dynamic circulation state during the impregnation process, which affects the dissolution and diffusion of active ingredients.

The whole is equipped with a high-efficiency stirring mechanism inside the impregnation tank 11. That is, the stirring paddle 17 is set inside the impregnation tank 11, and multiple layers of stirring blades are set on its outer side. The stirring blades are driven by the motor to stir the medicinal materials and solvents at different heights to ensure uniform mixing. The shape and speed of the stirring blades can be optimized according to the size of the impregnation tank 11 and the characteristics of the medicinal materials.

[0024] A pretreatment mechanism 2 is provided at one end of the upper part of the impregnation tank 11. The pretreatment mechanism 2 includes a guide hopper 22 located on one side of the opening at the upper part of the impregnation tank 11.

At this time, the crushed medicine can have more sufficient contact with the solvent in the impregnation tank 11. With the help of its stirring mechanism, the effective components of the medicine can be dissolved and diffused more quickly.

[0025] The bottom of the guide bucket 22 is fixedly connected to the outer wall of one end of the impregnation tank 11 via the support frame 21. The top center of the crushing box 23 has a feed inlet 24, and the bottom of the crushing box 23 has a discharge outlet matching the guide bucket 22. Three crushing rollers 25 are rotatably installed in an inverted triangle shape inside the crushing box 23. The two upper crushing rollers 25 are meshed with the middle crushing roller 25. The front end of the crushing box 23 is fixedly installed with a second drive motor 26 and a reduction gearbox 27. The front drive end of the second drive motor 26 is fixedly connected to the rear power input end of the reduction gearbox 27, and the rear power output end of the reduction gearbox 27 is fixedly connected to the middle crushing roller 25. The middle crushing roller 25 can be driven to rotate by the second drive motor 26 and the reduction gearbox 27, thereby driving the two crushing rollers 25 meshing with it to rotate, which can crush the medicinal materials entering through the upper feed inlet 24.

[0026] Four supports 12 are fixedly connected at equal angles on the upper part of the annular outer wall of the impregnation tank 11, which can support the entire device.

The whole is equipped with a pretreatment mechanism 2 for medicinal materials, that is, a crushing box 23 is set at the opening at the upper end of the immersion tank 11. The crushing box 23 is equipped with three crushing rollers 25 in an inverted triangular shape. The medicine to be processed can be put into the feed port 24 at the top of the crushing box 23. After being crushed by the three crushing rollers 25, the medicine can fall into the immersion tank 11 through the guide bucket 22 below. At this time, the crushed medicine can have more full contact with the solvent in the immersion tank 11. With the help of the stirring mechanism, the effective components of the medicine can be dissolved and diffused more quickly. The Chinese medicine is soaked in the solvent (such as water or ethanol), which allows the effective components to slowly dissolve into the solvent. After a certain period of time, the extract can be separated by the filter separator 18. Since a control valve 19 is fixedly installed at the outlet at the bottom of the filter separator 18, the discharge of the extract can be controlled by the control valve 19.
