Description

Technical Field

[0001] This utility model relates to the field of drug concentration technology, and more specifically, to a concentration sampling device. Background Technology

[0002] The active ingredients in traditional Chinese medicine (TCM) are usually in the form of plants, requiring extraction and concentration to achieve the desired medicinal effect. Traditional TCM decoction requires a lot of time and materials, and often results in waste. Concentrating TCM can efficiently extract drug components, reduce waste of materials and resources, and improve the stability and purity of the drug. For example, patent application number CN202222335849.7 describes a novel drug concentration device. The lower end of the concentration tank is equipped with a steam hood, and the lower end of the steam hood is equipped with a steam input pipe. A riser pipe connected to the steam hood is installed in the middle of the concentration tank. Expansion pipes are installed at equal intervals on the outer side of the riser pipe, and annular protrusions are installed on the inner side of the riser pipe above the expansion pipes. An overflow gap is formed on the inner side of the annular protrusions. This invention achieves diversion of the dilute liquid during its downward flow by setting up a separation hood and a liquid storage chamber, thereby gradually concentrating the dilute liquid. Steam rises inside the equipment via an ascending pipe, and the steam residence time inside the expansion pipe is extended by the expansion pipe and annular protrusion, thus improving the heating effect of the expansion pipe and accelerating the concentration cycle of the dilute liquid, thereby increasing the production efficiency of the equipment. However, in the above technical solution, the drug cannot fully contact the liquid, and the drug cannot be heated evenly, resulting in insufficient combination of the drug's properties and drug residue adhering to the inside of the steam tank, making it difficult to clean.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. 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 of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 , 2 As shown, a concentration sampling device includes a workbench 1, a heater 2 mounted on the upper surface of the workbench 1, a steam box 3 mounted on the upper surface of the heater 2, a condenser 4 mounted on the upper surface of the workbench 1, the steam box 3 connected to the condenser 4 via a pipe 6, a liquid outlet 5 provided around the periphery of the steam box 3, a drive assembly 9 provided on the upper surface of the workbench 1, a box cover 10 mounted on the upper surface of the workbench 1 via the drive assembly 9, the box cover 10 being located on the upper surface of the steam box 3, and a stirring and cleaning assembly 7 provided on the box cover 10.

[0022] like Figure 1 As shown, the steam box 3 is provided with observation windows 8 on its periphery, which facilitates the staff to observe the situation inside the steam box 3.

[0023] like Figure 1 , 2As shown, the driving assembly 9 includes a mounting rod 901, which is fixedly mounted on the upper surface of the workbench 1. A top plate 903 is fixedly mounted on the upper end of the mounting rod 901, and a hydraulic cylinder 902 is fixedly mounted on the lower surface of the top plate 903. A limit plate 904 is fixedly mounted on the output end of the hydraulic cylinder 902, and support rods 905 are fixedly mounted at equal intervals on the lower surface of the limit plate 904. The cover 10 is fixedly mounted on the lower surface of the support rods 905. Driven by the output end of the hydraulic cylinder 902, the limit plate 904 is moved downward, placing the cover 10 on the upper surface of the steam chamber 3. At this time, the filter cartridge 709 can be placed inside the steam chamber 3. The medicine is soaked in the liquid. At this time, the heater 2 works to heat the medicine and liquid inside the steam chamber 3, increasing the kinetic energy of the solvent molecules, thereby evaporating them into a gaseous state.

[0024] like Figure 2 , 3 As shown in Figures 4 and 5, the stirring and cleaning assembly 7 includes a servo motor 701 and positioning holes 702. The servo motor 701 is fixedly installed on the upper surface of the cover 10. Several positioning holes 702 are equidistantly opened on the lower surface of the cover 10. A rotating shaft 703 is fixedly installed at the output end of the servo motor 701. A filter cylinder 709 is installed in the middle of the rotating shaft 703. Several stirring rods 704 are equidistantly installed on the circumference of the rotating shaft 703. A connecting plate 706 is installed at the lower end of the rotating shaft 703. Scrapers 705 are fixedly installed on the upper surfaces of both sides of the connecting plate 706. The scrapers 705 are attached to the inner wall of the steam box 3. A positioning rod 711 is fixedly installed on the upper surface of the filter cylinder 709. The positioning rod 711 is located inside the positioning hole 702. A through hole 710 is opened through the inner surface of the filter cylinder 709. The rotating shaft 703 passes through the through hole 710. The upper surface of the connecting plate 706... The filter cylinder 709 has a threaded hole 708. A threaded sleeve 707 is fixedly installed at the lower end of the rotating shaft 703. The threaded sleeve 707 is located inside the threaded hole 708. When the medicine is placed inside the filter cylinder 709, it can prevent the medicine from coming into contact with the liquid. This prevents the residue in the medicine from coming into contact with the liquid, making it difficult to remove the residue from the liquid and affecting the concentration of the original solution. When the medicine is heated, the rotating shaft 703 is driven to rotate by the servo motor 701, which in turn drives several stirring rods 704 to rotate, stirring the medicine inside the filter cylinder 709. This ensures that the medicine and the liquid come into full contact, guaranteeing the full combination of the liquid and the medicine and ensuring the quality of the liquid. The rotation of the rotating shaft 703 also drives the scraper 705 to revolve, so that the scraper 705 rotates against the inner wall of the steam box 3, facilitating the cleaning of the inside of the steam box 3 by the operator and improving the convenience of this device.

[0025] The working principle of this concentrated sampling device:

[0026] In use, the stock solution is first stored inside the steam chamber 3. The medicine is placed in the middle of the filter cartridge 709, which is then inserted into the middle of the rotating shaft 703. The positioning rod 711 is positioned inside the positioning hole 702. The connecting plate 706 is then positioned at the lower end of the rotating shaft 703. By rotating the connecting plate 706, the threaded sleeve 707 is positioned inside the threaded hole 708, thus fixing the connecting plate 706 to the lower end of the rotating shaft 703 and positioning it directly below the filter cartridge 709. The filter cartridge 709 is then installed in the middle of the rotating shaft 704. The hydraulic cylinder 902 is then driven to move the limiting plate 904 downwards, positioning the cover 10 on the upper surface of the steam chamber 3. The filter cartridge 709 is now positioned inside the steam chamber 3. The drug is immersed in the liquid. Heater 2 heats the drug and liquid inside the steam tank 3, increasing the kinetic energy of the solvent molecules and causing them to evaporate into a gaseous state. The steam flows through pipe 6 into condenser 4, where it is cooled into water and then expelled. The remaining concentrate inside filter cartridge 709 is the concentrated concentrate. This device places the drug inside filter cartridge 709 to prevent direct contact between the drug and the liquid, thus preventing residues from coming into contact with the liquid and affecting the concentration. When the original solution is heated, the servo motor 701 drives the rotating shaft 703 to rotate, which in turn drives several stirring rods 704 to rotate, stirring the medicine inside the filter cylinder 709. This ensures that the medicine and liquid are in full contact, guaranteeing the full combination of the liquid and the medicine and ensuring the quality of the liquid. The rotation of the rotating shaft 703 also drives the scraper 705 to revolve, causing the scraper 705 to rotate against the inner wall of the steam box 3, facilitating the cleaning of the inside of the steam box 3 by the operator and improving the convenience of the device.

[0027] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
