Description
Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine testing technology, and in particular to a liquid filtration device for testing traditional Chinese medicine. Background Technology
[0002] The liquid filtration device for traditional Chinese medicine testing is used for filtering and separating traditional Chinese medicine liquids. It can realize solid-liquid separation, microbial detection and impurity removal. It has the advantages of high filtration efficiency, good quality, simple operation, wide range of applications and low risk of contamination, and can effectively ensure the accuracy and reliability of traditional Chinese medicine testing.
[0003] The traditional Chinese medicine (TCM) testing liquid filtration device consists of a filtration flask, a Buchner funnel, a vacuum pump or air pump, and connecting pipes. In the preparation stage, the filter media is laid and the equipment is connected and sealed. During the filtration stage, a negative pressure is created by the vacuum pump or air pump, and the pressure difference is used to force the liquid to pass through the filter paper or filter membrane to achieve solid-liquid separation. After the pressure is balanced in the final stage, the filtrate is collected and the filter media is processed to complete the entire filtration testing process.
[0004] Existing traditional Chinese medicine (TCM) testing liquid filtration devices cannot achieve rapid sealing and connection between the conical flask and the liquid tank. This not only reduces work efficiency and prolongs the testing cycle by extending the operation time, but also easily leads to loose connections, causing liquid leakage, contaminating the experimental environment, affecting the accuracy of results, and increasing the risk of external contamination of the liquid, interfering with the reliability of test results. Poor sealing can also disrupt negative pressure stability, reduce filtration effect and liquid quality, and affect subsequent component analysis and other tests. Therefore, a TCM testing liquid filtration device is proposed to solve the above problems. Utility Model Content

[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a traditional Chinese medicine testing liquid filtration device, including a base plate 1. The base plate 1 serves as the basic load-bearing structure of the entire device. Its flat and stable surface provides a reliable mounting platform for the parts and can effectively disperse the pressure generated during the operation of the device, ensuring the overall stability of the device. A vacuum pump 2 is fixedly connected to the top of the base plate 1. The vacuum pump 2 serves as the power source for filtration. It generates negative pressure through high-speed operation, providing the necessary suction for the filtration process of the traditional Chinese medicine liquid, thereby accelerating the filtration speed of the liquid and significantly improving work efficiency.
[0033] The top of the vacuum pump 2 is fixedly connected to the suction pipe 17, which is responsible for transmitting the negative pressure generated by the vacuum pump 2 to the liquid inlet pipe 4, ensuring the formation of a pressure difference in the filtration device, so that the liquid can pass smoothly through the filter material to achieve solid-liquid separation. The design of its sliding connection inside the liquid inlet pipe 4 makes it easy to disassemble and maintain. The top of the base plate 1 is slidably connected to the conical flask 3, which is used to receive the filtered liquid. Its unique conical structure not only increases the internal volume and facilitates the storage of the liquid, but also allows the liquid to be better concentrated at the bottom of the flask during the filtration process, reducing residue. At the same time, the sliding connection makes it easy to quickly replace or remove the liquid for collection after filtration.
[0034] The top of the conical flask 3 is slidably connected to an inlet pipe 4, which is a channel connecting the liquid tank 5 and the conical flask 3. It is responsible for guiding the Chinese medicine liquid to be filtered to flow smoothly into the conical flask 3. The sliding connection design between the inlet pipe 4 and the conical flask 3 ensures airtightness while facilitating quick adjustment or replacement of the inlet pipe 4 under different experimental needs. The top of the inlet pipe 4 is fixedly connected to a fixing post 12, which provides a stable base for the installation of the liquid tank 5. The internal slot design of the fixing post 12 cooperates with the fixing block 16 on the outside of the liquid tank 5, realizing the quick installation and disassembly of the liquid tank 5, effectively improving the convenience of experimental operation.
[0035] The material tank 5 is slidably connected inside the fixed column 12. The material tank 5 is used to hold the Chinese medicine liquid to be filtered. Its sliding connection with the fixed column 12, along with the slot and fixing block 16 structure, allows for precise positioning during installation and easy separation during disassembly, greatly improving work efficiency. Multiple fixing blocks 16 are fixedly connected to the outside of the material tank 5. The fixing blocks 16 engage with the slots inside the fixed column 12. When the material tank 5 rotates, the fixing blocks 16 slide in the slots and eventually engage at the corners of the slots, achieving a stable installation of the material tank 5 and preventing the material tank 5 from loosening or falling off during the filtration process.
[0036] The fixed column 12 has a slot inside, which precisely matches the fixed block 16. Through a specific shape design, it provides accurate positioning and a firm connection for the installation of the liquid tank 5, ensuring that the liquid tank 5 and the fixed column 12 are tightly connected under the negative pressure environment of filtration. The fixed column 12 has a sealing shell 13 fixedly connected inside. The sealing shell 13 provides installation space and protection for the sealing ring 15. Its smooth internal structure helps the sealing ring 15 to slide smoothly, and at the same time, it limits the sealing ring 15 to ensure that it maintains the correct position during the sealing process.
[0037] The sealing shell 13 has a sliding connection of a sealing ring 15 inside. The sealing ring 15 is a key component to ensure the sealing of the connection between the liquid tank 5 and the fixed column 12. When the liquid tank 5 is installed, it is squeezed and deformed to fit tightly against the bottom of the liquid tank 5, effectively preventing leakage of the liquid and avoiding contamination of the experimental environment and affecting the test results. The top of the sealing ring 15 is slidably connected to the bottom of the liquid tank 5. This connection method allows the sealing ring 15 to move accordingly with the installation and disassembly of the liquid tank 5. While achieving a seal, it does not hinder the installation and disassembly of the liquid tank 5.
[0038] Multiple springs 14 are fixedly connected to the bottom of the sealing ring 15. The springs 14 provide upward elastic force to the sealing ring 15. When the liquid tank 5 is installed with the compression sealing ring 15, the springs 14 compress and store force. After the fixing block 16 is inserted into the corner of the slot, the springs 14 release the elastic force, pushing the sealing ring 15 tightly against the liquid tank 5, further enhancing the sealing effect. The other end of the springs 14 is fixedly connected to the inside of the sealing shell 13. This fixing method ensures that the springs 14 remain stable during the extension and retraction process, and can continuously provide reliable elastic support for the sealing ring 15. A limiting component is fixedly connected to the top of the base plate 1. The limiting component serves to fix the liquid inlet pipe 4, ensuring that the position of the liquid inlet pipe 4 is stable during the filtration process, and avoiding the impact of shaking on the filtration effect and normal operation of the device.
[0039] Reference Figures 1 to 3 The limiting component includes multiple limiting rods 6, which are vertically fixed to the top of the base plate 1 to form a stable frame structure. This provides external support and limitation for the liquid inlet pipe 4, ensuring that the liquid inlet pipe 4 will not undergo significant displacement during the filtration process. Each of the multiple limiting rods 6 is fixedly connected to a fixing plate 7. The fixing plate 7 increases the connection area between the limiting rods 6 and the clamping plate 9, making the clamping plate 9 more evenly stressed when fixing the liquid inlet pipe 4, thus improving the stability and reliability of the fixation. Two limiting rods 11 are fixedly connected to one side of the fixing plate 7. The limiting rods 11 guide and limit the movement of the clamping plate 9, preventing the clamping plate 9 from shifting or tilting during opening and closing, and ensuring that the clamping plate 9 can accurately clamp or release the limiting rods 6.
[0040] A spring 8 is fixedly connected to the outer side of the fixed plate 7. The spring 8 provides a reset force for the clamping plate 9. When the clamping plate 9 is pulled open to place the limiting rod 6, the spring 8 releases its force to push the clamping plate 9 back to its original position, tightly clamping the limiting rod 6 and achieving a firm fixation of the limiting rod 6. The other end of the spring 8 is fixedly connected to the clamping plate 9. The clamping plate 9, through its close fit with the limiting rod 6, stably fixes the liquid inlet pipe 4 between the limiting rods 6, ensuring that the liquid inlet pipe 4 will not loosen or shift during the filtration process. Connecting plates 10 are fixedly connected to both sides of the clamping plate 9. The connecting plates 10 cooperate with the limiting rod 11 to further enhance the stability of the clamping plate 9 when it moves, ensuring that the clamping plate 9 can slide smoothly along the direction of the limiting rod 11 and accurately complete the fixation and release of the limiting rod 6. The connecting plate 10 has a hole inside, and the outer side of the limiting rod 11 is slidably connected to the inside of the hole. This sliding connection method allows the connecting plate 10 to move smoothly on the limiting rod 11, providing a flexible and stable movement track for the opening and closing of the clamping plate 9.
[0041] Working principle: When the staff needs to filter the medicine, they can separate the two clamps 9 in different directions. Then, the limiting rod 6 is placed inside the two clamps 9. The clamps 9 can then be released. The spring 8 connected to the back of the clamps 9 will be squeezed, causing the clamps 9 to be pushed to the outside of the limiting rod 6 after they are released. This restricts the limiting rod 6 to the inside of the two clamps 9.
[0042] Then, the inlet pipe 4 is placed outside the limiting rod 6, connecting the inlet pipe 4 to the limiting rod 6. Next, the bottom of the liquid tank 5 is slid into the fixed post 12 connected to the top of the inlet pipe 4. The fixed post 12 has multiple slots inside, which correspond to multiple fixed blocks 16 connected to the outside of the liquid tank 5. After the fixed blocks 16 slide into the slots, the liquid tank 5 can be rotated, causing the liquid tank 5 to slide along the fixed blocks 16 inside the slots. Once the liquid tank 5 slides into the fixed post 12, it will seal the tank. When ring 15 is pressed downwards, it causes the sealing ring 15 to press against the multiple springs 14 connected to its bottom. When the fixing block 16 is rotated to the corner of the slot, the liquid tank 5 can be released. At this time, the multiple springs 14 will push the sealing ring 15 upwards, causing the sealing ring 15 to push against the liquid tank 5. This will make the fixing block 16 and the slot more tightly connected. When it is necessary to remove the liquid tank 5, the liquid tank 5 can be rotated so that the fixing block 16 rotates to the corner of the slot, and the liquid tank 5 can be taken out from the inside of the fixing column 12.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
