[0001] This utility model relates to the field of pharmaceutical extraction technology, specifically to an extraction device for pharmaceutical applications. Background Technology

[0002] In the pharmaceutical manufacturing process, extraction equipment is needed to extract useful components from the pharmaceutical solution. Pharmaceutical extraction equipment is an industrial device used to separate and extract effective components from raw materials. It is mainly used in the pre-processing stage of drug production, such as extracting effective active ingredients from raw materials such as Chinese medicinal herbs and plants.

[0003] For example, CN207203526U discloses a pharmaceutical extraction device, the structure of which includes a decoction tank, a drug delivery pipe, a drug storage tank, support feet, a drug addition port, a sealing cover, a slag discharge port, an exhaust port, a control console, switch buttons, a temperature adjustment button, a coupling, a rotating shaft, a motor, an external power cord, a stirring blade, a heating device, a water pump, a rotating shaft, a second motor, a drug discharge port, and a switch valve. By setting up a camera, the device can record the drug extraction process and status in the decoction tank during use, and can play it on a data display screen, solving the problem of not being able to view the changes in the decoction process of the medicinal materials. By setting up a component detector, the device can detect the components of the extracted drug during use, thereby obtaining data such as drug concentration, which can be displayed on the data display screen, solving the problem of not being able to view the concentration of the extracted drug.

[0004] However, the existing technology has the problem that the mixing effect of the drug solution is not sufficient, and the drug solution lacks a filtration mechanism to filter the drug solution when it is extracted and discharged. As a result, the extracted drug solution contains some residues, which affects the quality of the pharmaceutical product. For example, the comparative patents listed above have this problem.

[0005] To address these issues, we propose a pharmaceutical extraction device. Utility Model Content

[0028] 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.

[0029] Please see Figures 1-6 The present invention provides the following technical solution:

[0030] To address the problems in existing technologies, such as insufficient mixing of the medicinal solution and the lack of filtration during extraction, resulting in residues in the extracted solution and affecting pharmaceutical quality, this solution provides a pharmaceutical extraction device comprising an extraction tank 1, a feed hopper 4, a motor 5, and a stirring rod 6. A heating cylinder 3 is fixed to the outside of the extraction tank 1, and a heating component is installed inside the heating cylinder 3 to heat the medicinal solution in the extraction tank 1. A valve 8 is installed at the lower end of the extraction tank 1. The lower end of valve 8 is provided with a liquid filtration assembly. The liquid filtration assembly consists of a filter cylinder 9 fixed to the lower end of valve 8, a filter bucket 10 sleeved on the outer side of the lower end of filter cylinder 9, and a filter screen 11 snapped into the middle of filter bucket 10. At the same time, the left and right sides of the upper end of filter bucket 10 are provided with fixing components for limiting the position. The fixing components drive the filter bucket 10 and filter screen 11 to form a disassembly structure at the lower end of filter cylinder 9. The fixing components include a movable plate 14, a fixing rod 15, a connecting plate 16, a connecting column 17, and a connecting cap 18 provided on the outer side of the upper end of filter cylinder 9.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the extraction tank 1 is placed on the ground by the fixing frame 2. The medicinal raw materials and an appropriate amount of water are added to the extraction tank 1 through the feeding hopper 4 in a specific ratio. After addition, the outer cover is secured to the upper end of the feeding hopper 4. Then, the medicinal liquid in the extraction tank 1 is heated by the heating component inside the heating cylinder 3. A temperature sensor installed inside the extraction tank 1 monitors the internal temperature to maintain the medicinal liquid at a suitable extraction temperature. The motor 5 installed on the top of the extraction tank 1 is started by an external controller. A stirring rod 6 is fixedly connected to the output end of the motor 5. 5 drives the stirring rod 6 to rotate in the extraction tank 1, thereby fully stirring and mixing the medicine liquid in the extraction tank 1. Through the setting of the exhaust reflux assembly 7, the exhaust reflux assembly 7 includes an exhaust pipe inserted into the upper left end of the extraction tank 1, a condenser connected to the exhaust pipe, an exhaust pipe set on the left side of the condenser and a reflux pipe installed at the lower end of the exhaust pipe. At the same time, the other end of the reflux pipe is connected to the extraction tank 1. The gas generated during the stirring process is discharged through the exhaust pipe, condensed in the condenser and then discharged to the outside through the exhaust pipe, and part of the liquid is returned to the extraction tank 1 through the reflux pipe.

[0032] In addition, when the extract is complete and the liquid is drained, such as Figure 4 , Figure 5 and Figure 6 As shown, opening valve 8 at the lower end of extraction tank 1 allows the liquid medicine to enter filter cylinder 9 and filter hopper 10 through valve 8. After being filtered by filter screen 11, it is discharged and collected. Sealing ring 12 is fitted between filter hopper 10 and filter screen 11, and between filter screen 11 and filter cylinder 9, improving the sealing effect of the filtered liquid. After discharge, rotating the connecting cap 18 threaded onto the outer surface of connecting column 17 moves the connecting cap 18 downwards, releasing the limit on fixing rod 15. Then, fixing rod 15 is pulled down. The fixed rod 15 slides between itself and the connecting column 17. The fixed rod 15, together with the connecting plate 16, drives the connecting column 17 to move downward. The movable plate 14 loosens its engagement with the T-block 13 and then pulls the movable plate 14 outward. The upper end of the movable plate 14 slides between itself and the connecting plate 16, while the lower end of the movable plate 14 disengages from the T-block 13, thereby loosening the limit between the filter cylinder 9 and the filter hopper 10, allowing the filter hopper 10 to be disassembled. This facilitates the disassembly, cleaning, and replacement of the filter screen 11, preventing residue and clogging.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
