Description

Technical Field

[0001] This utility model relates to the field of filtration and impurity removal technology, and in particular to a filtration and impurity removal device for processing oral liquids of traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine oral liquids are single-dose packaged liquid preparations made from Chinese medicinal herbs through modern extraction, purification, and concentration processes, with the addition of appropriate excipients. They retain the rapid absorption and onset of action characteristic of traditional decoctions, while also achieving precise dosage and controllable quality through standardized production processes. They offer advantages such as convenient administration, improved taste, and portability, making them an important dosage form in the modernization of traditional Chinese medicine, and are widely used in the treatment of colds, coughs, and digestive system diseases.

[0003] Currently, filtration and impurity removal is one of the key steps in the extraction stage of traditional Chinese medicine oral liquid processing, mainly used to remove suspended particles, dregs and other insoluble impurities from the liquid.

[0004] The prior art disclosure number CN222131112U describes a filtration device for processing oral liquids of traditional Chinese medicine, which includes a filter box, a filter plate fixedly installed on the inner wall of the filter box, a scraping mechanism above the filter plate, and a collection mechanism on the right side of the filter box. The scraping mechanism includes a moving part and a scraping part, which is used to scrape off impurities above the filter plate. The collection mechanism includes a connecting part and a collecting part, which is used to collect impurities.

[0005] This equipment can clean the filter plates, but it has a cleaning defect: the scraper and rubber pad are always in contact with the filter plates, causing the recently filtered impurities to be pushed away from the collection mechanism with each return stroke. Over time, this impurity accumulates. Secondly, the filter frame of the collection mechanism needs to be manually removed to clean the filter residue. However, during removal, the filter box is connected to the outside. If the flow rate of the chemical solution is high or the equipment is running continuously, unfiltered chemical solution may leak from the discharge trough, resulting in material waste.

[0006] Therefore, a filtration and impurity removal device for processing oral liquids of traditional Chinese medicine is proposed. Utility Model Content

[0007] This invention is a filtration and impurity removal device for processing oral liquids of traditional Chinese medicine, proposed to overcome the shortcomings of existing technologies.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a filtration and impurity removal device for processing oral liquid of traditional Chinese medicine, comprising an upper shell, wherein a circular filter plate is fixedly connected to the inner surface of the upper shell, and a lower shell is fixedly connected to the bottom of the circular filter plate;

[0009] A triangular shell is fixedly connected to the inner surface of the upper shell. A drive assembly is installed between the triangular shell and the upper shell. A mounting shaft is fixedly connected to the movable end of the drive assembly. Multiple arc-shaped scrapers are fixedly connected to the outer surface of the mounting shaft.

[0010] A collection pipe is fixedly connected to one side of the bottom of the circular filter plate, and a housing is fixedly connected to the bottom of the collection pipe. A manual valve is installed inside the housing, and an abutment plate slides up and down on the movable end of the manual valve.

[0011] A collection filter frame is sealed and inserted into one side of the outer surface of the housing, and a baffle is fixedly connected to one end of the collection filter frame, with the abutment plate matching the baffle.

[0012] A recycling pipe is fixedly connected between the bottom of the outer shell and the lower shell.

[0013] Furthermore, the drive assembly includes a motor, which is fixedly mounted on the outer surface of the upper shell via a mounting bracket. The drive end of the motor is fixedly connected to a long shaft, which extends through the outer wall of the upper shell into the interior of the triangular shell and is rotatably connected to the triangular shell. The end of the long shaft is fixedly connected to a driving bevel gear, and a driven bevel gear is meshed with one side of the outer surface of the driving bevel gear. The mounting shaft is fixedly mounted on the bottom of the driven bevel gear and can drive the mounting shaft to rotate.

[0014] Furthermore, the mounting shaft and the triangular shell are connected in a sealed rotational manner, and the triangular shell provides support for the mounting shaft, which facilitates the installation of the mounting shaft.

[0015] Furthermore, the mounting shaft and the arc-shaped scraper are both attached to the top of the circular filter plate, which facilitates the cleaning of the circular filter plate by the arc-shaped scraper.

[0016] Furthermore, the manual valve includes a valve plate, which is sealed and fitted to the inner top of the housing. One end of the valve plate is fixedly connected to a movable frame, which is installed through the housing and is slidably connected to the housing in a sealed manner. The movable frame is slidably connected to the abutment plate, and the movable frame has a limiting effect on the abutment plate, which can ensure the stability of the abutment plate's up and down movement.

[0017] Furthermore, a handwheel is provided on one side of the movable frame, and a screw is fixedly connected to one side of the outer surface of the handwheel. The movable frame is threaded onto the outer surface of the screw, and the screw is rotatably connected to the housing. The handwheel facilitates manual driving of the screw rotation.

[0018] Furthermore, the bottom of the circular filter plate is fixedly connected to four support legs, which provide support and raise the overall height.

[0019] The beneficial effects of this utility model are:

[0020] This utility model relates to a filtration and impurity removal device for processing oral liquids of traditional Chinese medicine. It comprises a circular filter plate, a triangular shell, a drive assembly, an arc-shaped scraper, a collection pipe, a manual valve, a housing, a contact plate, a collection filter frame, a baffle, and a recovery pipe. Each time the device is cleaned, impurities on the filter plate are pushed into the collection pipe, completely preventing backflow and accumulation. Furthermore, when the collection filter frame is removed, the collection pipe can be temporarily sealed to prevent leakage and material waste. Simultaneously, the valve's linkage control fixes the contact plate to the collection filter frame, achieving "one valve, two controls"—opening the valve fixes the filter frame and facilitates discharge; closing the valve releases the filter frame and seals the pipeline, significantly simplifying the operation process and reducing the number of steps.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 5 As shown, a filtration and impurity removal device for processing oral liquid of traditional Chinese medicine is disclosed, including an upper shell 1, a circular filter plate 6 fixedly connected to the inner surface of the upper shell 1, and a lower shell 4 fixedly passing through the bottom of the circular filter plate 6. The circular filter plate 6 is composed of a filter plate body and an annular plate. The filter plate body is set inside the annular plate. The upper shell 1 is fixedly sleeved on the outer surface of the annular plate, and the lower shell 4 is fixedly installed at the bottom of the annular plate.

[0031] A triangular shell 9 is fixedly connected to the inner surface of the upper shell 1. A drive assembly is installed between the triangular shell 9 and the upper shell 1. A mounting shaft 10 is fixedly connected to the movable end of the drive assembly. The drive assembly includes a motor 2, which is fixedly mounted on the outer surface of the upper shell 1 by a mounting bracket. A long shaft 14 is fixedly connected to the drive end of the motor 2. The long shaft 14 extends through the outer wall of the upper shell 1 into the interior of the triangular shell 9 and is rotatably connected to the triangular shell 9. A drive bevel gear 13 is fixedly connected to the end of the long shaft 14. A driven bevel gear 12 is meshed on one side of the outer surface of the drive bevel gear 13. The mounting shaft 10 is fixedly mounted on the bottom of the driven bevel gear 12. The mounting shaft 10 and the long shaft 14 are rotatably connected to the triangular shell 9 through bearing seats. The bearing seats are fixedly connected to the triangular shell 9. The inner ring of the bearing inside the bearing seat is fixedly connected to the mounting shaft 10 and the long shaft 14 respectively. A sealing ring is fixedly installed on the outer surface of the mounting shaft 10. The sealing ring is placed below the bearing seat and seals against the triangular shell 9.

[0032] The mounting shaft 10 is sealed and rotatably connected to the triangular shell 9. Multiple arc-shaped scrapers 8 are fixedly connected to the outer surface of the mounting shaft 10. The mounting shaft 10 and the arc-shaped scrapers 8 are both attached to the top of the circular filter plate 6. The mounting shaft 10 is treated with nitriding or hard chrome plating to improve the wear resistance of the shaft and extend its service life. The arc-shaped scrapers 8 are made of wear-resistant polymer materials (such as polyurethane and ultra-high molecular weight polyethylene) to ensure that the scrapers will not wear out too quickly during long-term scraping.

[0033] A collection pipe 11 is fixedly connected to one side of the bottom of the circular filter plate 6. A housing 3 is fixedly connected to the bottom of the collection pipe 11. A manual valve is installed inside the housing 3. The movable end of the manual valve has an abutment plate 21 that slides up and down. The manual valve includes a valve plate 15, which is sealed and fitted to the inner top of the housing 3. A movable frame 16 is fixedly connected to one end of the valve plate 15. The movable frame 16 passes through the housing 3 and is slidably connected to the housing 3. The movable frame 16 and the abutment plate 21 are slidably connected up and down. A handwheel 18 is provided on one side of the movable frame 16. A screw 17 is fixedly connected to one side of the outer surface of the handwheel 18. The movable frame 16 is threaded onto the outer surface of the screw 17. The screw 17 is rotatably connected to the housing 3. A sealing gasket is fixedly connected to the bottom of the valve plate 15. The sealing gasket fits against the inner top of the housing 3 to ensure the sealing between the valve plate 15 and the housing 3.

[0034] A collection filter frame 19 is sealed and inserted into one side of the outer surface of the housing 3. A baffle 20 is fixedly connected to one end of the collection filter frame 19, and the abutment plate 21 matches the baffle 20. The collection filter frame 19 can drain impurities.

[0035] A recycling pipe 7 is fixedly connected between the bottom of the outer shell 3 and the lower shell 4.

[0036] The bottom of the circular filter plate 6 is fixedly connected to four support legs 5, which raise the overall height and facilitate use.

[0037] Drug filtration stage:

[0038] The liquid medicine enters from the upper shell 1, flows through the circular filter plate 6 for filtration, the residue is trapped on the surface of the filter plate, and the filtrate enters the lower shell 4 through the circular filter plate 6 and is finally discharged from the bottom.

[0039] Filter residue cleaning stage:

[0040] When filter cake buildup affects filtration efficiency, motor 2 is started, driving the long shaft 14 to rotate. The active bevel gear 13 at the end of the long shaft 14 drives the driven bevel gear 12, causing the mounting shaft 10 to drive multiple arc-shaped scrapers 8 to rotate along the surface of the circular filter plate 6.

[0041] During rotation, the arc-shaped scraper 8 scrapes the filter residue unidirectionally toward the collection pipe 11, preventing the filter residue from flowing back and accumulating during the return stroke.

[0042] Filter cake collection and leak prevention control:

[0043] The filter residue enters the collection filter frame 19 inside the shell 3 along the collection pipe 11. After secondary filtration through the collection filter frame 19, the filtrate flows back to the lower shell 4 through the recovery pipe 7 to avoid waste.

[0044] When the collection filter frame 19 needs to be cleaned, turn the handwheel 18 to move the screw 17, which in turn moves the movable frame 16 and valve plate 15 horizontally. The valve plate 15 then closes the collection pipe 11 to prevent leakage of the medicine. At the same time, the abutment plate 21 moves with the movable frame 16, releasing the restriction on the baffle 20. Then, lift the abutment plate 21, and the collection filter frame 19 can be pulled out for cleaning.

[0045] After cleaning, all components were reset.

[0046] It should be noted that, in actual use, an existing microcontroller can be added. The microcontroller is used to control the operation of motor 2. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
