Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a centrifugal impurity removal device for concentrating traditional Chinese medicine. Background Technology

[0002] In the processing of traditional Chinese medicine (TCM), medicinal materials are decocted or soaked to form an extract containing active ingredients. However, these extracts often contain a large amount of filter residue, soil, and other impurities. Direct concentration of these extracts not only affects the purity and quality of the final product but also increases the frequency of cleaning and maintenance costs of the concentration equipment. Therefore, in TCM concentration processes, impurity removal is usually necessary to improve the quality of the extract. While existing centrifugal impurity removal equipment can effectively separate solid impurities from the extract, the filter screen in the discharge pipe is prone to clogging after prolonged operation, often requiring disassembly and cleaning, which is inconvenient and inefficient. To address this, we propose a centrifugal impurity removal device for TCM concentration. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a centrifugal impurity removal device for concentrating traditional Chinese medicine. A rotatable filter screen is set inside the medicine liquid discharge pipe. When the filter screen needs to be cleaned, simply rotate the filter screen to clean the light suspended matter and impurities on the filter screen. No disassembly and cleaning are required. The operation is simple and the cleaning is convenient, which greatly improves the work efficiency and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal purification device for concentrating traditional Chinese medicine, comprising a horizontal centrifuge, wherein a feed inlet is provided on one side of the horizontal centrifuge, and a liquid discharge pipe and a separated material discharge pipe are respectively provided on the lower surface of the horizontal centrifuge, wherein a rotatable filter screen is provided inside the liquid discharge pipe, and a drive motor is installed on a support frame on the side of the horizontal centrifuge away from the feed inlet, wherein the output shaft of the drive motor passes through the side surface of the support frame and is connected to a pulley assembly, and the pulley assembly is connected to a screw pusher inside the horizontal centrifuge.

[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] Please see Figures 1-4 This utility model provides a technical solution: a centrifugal purification device for concentrating traditional Chinese medicine, including a horizontal centrifuge 1. A feed inlet 2 is provided on one side of the horizontal centrifuge 1. A liquid discharge pipe 3 and a separated material discharge pipe 4 are respectively provided on the lower surface of the horizontal centrifuge 1 for discharging the traditional Chinese medicine liquid and the separated sediment, etc. A rotatable filter screen 9 is provided inside the liquid discharge pipe 3. When centrifuging to remove impurities from the liquid, the filtering plane of the filter screen 9 is perpendicular to the axis of the liquid discharge pipe 3, filtering out light suspended solids and impurities in the liquid discharged from the liquid discharge pipe 3. When the filter screen 9 needs to be cleaned, simply rotate the filter screen 9 to tilt it, make it vertical, or flip it 180°, and then inject clean water or cleaning solution into the horizontal centrifuge 1 to clean the light suspended matter and impurities on the filter screen 9. No disassembly is required for cleaning, the operation is simple and the cleaning is convenient, which greatly improves the work efficiency. The drive motor 5 is installed on the support frame on the side away from the feed port 2 of the horizontal centrifuge 1. The output shaft of the drive motor 5 passes through the side surface of the support frame and is connected to the pulley group 6. The pulley group 6 is connected to the screw pusher inside the horizontal centrifuge 1.

[0018] The horizontal centrifuge 1 is also equipped with a differential, cleaning pipe, drum, bearing seat, cover, material distribution device, shock absorber and other devices. Its structure is roughly the same as that of the horizontal centrifuges commonly used in the prior art, and will not be described in detail here.

[0019] A ring-shaped filter frame is fixedly installed on the outer peripheral surface of the filter screen 9. A rotating shaft 8 is fixedly installed on the outer surface of the filter frame. The axis of the rotating shaft 8 is perpendicular to the axis of the medicine discharge pipe 3. The end of the rotating shaft 8 passes through the outer surface of the medicine discharge pipe 3 and is fixedly connected to the rotating handle 7. A rotary seal is provided between the rotating shaft 8 and the corresponding through hole on the medicine discharge pipe 3. The rotating shaft 8 can be operated by rotating the handle 7 to drive the filter screen 9 to rotate, so that the filter screen 9 can be cleaned without disassembling the filter screen 9 or backwashing. This makes it easy to clean the filter screen and also makes it easy to discharge the cleaned impurities to the outside.

[0020] In a preferred embodiment, the rotating handle 7 is rod-shaped, and two fixing seats 10 are provided on the outer surface of the liquid discharge pipe 3. The two fixing seats 10 are respectively located on both sides of the rotating shaft 8. The side surface of the fixing seats 10 is provided with a groove that matches the rotating handle 7. The axis of the rotating handle 7 is perpendicular to the filter surface of the filter screen 9. When the rotating handle 7 is in a vertical state, its two ends are respectively locked in the grooves of the two fixing seats 10. At this time, the axis of the filter screen 9 coincides with the axis of the liquid discharge pipe 3, and the liquid can be filtered. Since the rotating handle 7 is locked and fixed, the rotating shaft 8 and the filter screen 9 are also fixed, and will not deflect under the impact of the liquid, thus affecting the filtration of the liquid.

[0021] The two fixed brackets 10 are symmetrically arranged with the center of the rotating shaft 8 as the center of symmetry, so that the rotating handle 7 can drive the rotating shaft 8 and the filter screen 9 to rotate while being fixed by the slot.

[0022] The two fixed brackets 10 are not limited to being on the same vertical line, and their slots limit the rotation range of the rotating handle 7 to 0-180°.

[0023] In a further preferred embodiment, a rotating plate 11 is rotatably provided on the side surface where the slot is located on the fixed card seat 10. After the rotating handle 7 enters the slot of the fixed card seat 10, the rotating plate 11 can rotate to fix it, which further improves the stability and firmness of the filter screen 9 when filtering the medicine liquid and ensures the subsequent concentration and purification effect of the medicine liquid.

[0024] Furthermore, a limiting block 12 corresponding to the rotating plate 11 is fixedly provided on the side surface of the fixed card slot on the fixed card seat 10. The two fixed card seats 10 are symmetrically arranged on the upper and lower sides of the rotating shaft 8. The limiting block 12 is fixedly provided on the lower part of the side surface of the fixed card seat 10. The limiting block 12 is used to fix the rotating plate 11 and prevent it from rotating automatically under the action of gravity, thus failing to fix the rotating handle 7.

[0025] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
