[0018] This utility model provides, for example Figures 1 to 6 The multi-channel liquid separation and storage tank shown includes: a cylindrical body 1, a top cover plate 7 on the top of the cylindrical body 1, multiple sets of support legs 3 on the bottom of the cylindrical body 1, multiple sets of observation windows 2 evenly arranged in a circumferential array on the side wall of the cylindrical body 1, and a scale line on the cylindrical body 1 located on one side of the observation window 2, and a multi-channel liquid storage assembly inside the cylindrical body 1, the multi-channel liquid storage assembly being used to enable the cylindrical body 1 to separate and store multiple liquids; In terms of drug solution separation, storage, flow management, and monitoring, the innovative design of a cylindrical body 1 and a multi-channel liquid storage component installed inside it, along with multiple sets of installation slots 5 and liquid separators 8, effectively isolates various drug solutions, avoiding cross-contamination and ensuring the purity and stability of different drugs. Secondly, both the inlet pipe 4 and the outlet pipe 9 are equipped with check valves to ensure unidirectional flow of the drug solution during storage and transportation, eliminating the possibility of backflow and improving operational safety and ease of use. Furthermore, the observation window 2 and scale lines further enhance the intuitiveness of liquid level monitoring, allowing operators to clearly and promptly understand the liquid level in each storage chamber, ensuring more convenient and rapid use and replenishment of the drug solution. For cleaning and maintenance of the tank, at least one cleaning port is provided on the upper cover plate 7. A detachable CIP spray ball can be installed at the cleaning port. The CIP spray ball is connected to the cleaning port via a flange and can rotate to achieve full coverage cleaning of the inner walls of each liquid storage chamber. A dedicated drain pipe 9 is provided at the bottom for thorough cleaning without disassembling the equipment, improving the hygiene of the equipment. Meanwhile, the design of anti-corrosion sealing strips between the liquid separator 8 and the mounting groove 5, and between the liquid separator 8 and the fixed column 6, is also noteworthy. The cylindrical body 1 and the internal liquid separator 8 are preferably made of 316L stainless steel, while the anti-corrosion sealing strips in contact with the pharmaceutical liquid are preferably made of EPDM or PTFE material. The inner surface of the cylindrical body 1 is polished, with a surface roughness Ra≤0.8μm, further enhancing the airtightness of the equipment to meet pharmaceutical hygiene requirements, reducing the risk of reaction between the pharmaceutical liquid and equipment materials, and ensuring the safety and efficacy of the medicine.
[0019] Furthermore, in this example, such as Figure 2 , Figure 3 and Figure 4 As shown, the multi-channel liquid storage assembly includes multiple sets of mounting slots 5, which are evenly arranged in a circular array on the inner and bottom walls of the cylindrical body 1. Liquid-separating plates 8 are slidably inserted into the mounting slots 5, and a fixing post 6 is located at the central axis of the bottom of the cylindrical body 1. One end of the liquid-separating plate 8 is slidably engaged in the mounting slot 5, and the other end is slidably engaged in the outer wall of the fixing post 6. A fixing block 15 is provided at the top of the end of the liquid-separating plates 8 near the fixing post 6. Corresponding adjacent sets of liquid-separating plates 8 are mounted on the upper cover plate 7. A connecting channel 12 is provided between the two, and a liquid inlet pipe 4 is installed at the connecting channel 12 on the upper end face of the upper cover plate 7. A conical liquid inlet nozzle 11 is installed at the connecting channel 12 on the lower end face of the upper cover plate 7. The radius of the conical liquid inlet nozzle 11 gradually increases from top to bottom in the vertical direction. An anti-direct spray cone 13 is provided in the inner cavity of the conical liquid inlet nozzle 11, and the anti-direct spray cone 13 is connected to the inner wall of the conical liquid inlet nozzle 11 by a mounting rod 14. The cylindrical body 1 serves as the main body of the storage tank, internally equipped with a multi-channel liquid storage assembly. Multiple sets of mounting slots 5 are evenly distributed within the formed independent liquid storage areas. Inserted baffles 8 effectively isolate different liquids, preventing cross-contamination and ensuring the purity and stability of the drugs. Multiple connecting channels 12 on the upper cover 7, in conjunction with the inlet manifold 4 and the conical inlet nozzle 11, reduce the impact force of the liquid entering the storage chamber after it is introduced, minimizing its influence on the liquid. The anti-direct-spray cone 13 ensures even distribution of the liquid. Meanwhile, a transparent observation window 2 and scale lines allow operators to visually monitor the liquid level. The bottom outlet channel, in conjunction with the drain manifold 9, is equipped with a check valve to ensure unidirectional flow of the liquid during extraction, thereby improving safety and convenience. Furthermore, the use of anti-corrosion sealing strips enhances the equipment's sealing performance, reducing the risk of reaction between the liquid and equipment materials, comprehensively ensuring the safety and efficacy of the drugs.
[0020] Furthermore, in this example, such as Figure 3 , Figure 4 and Figure 5 As shown, the bottom of the cylindrical body 1 has outlet channels corresponding to the positions between two adjacent sets of liquid-blocking plates 8. The outer wall of the cylindrical body 1 also has drainage manifolds 9 corresponding to the outlet channels. The other ends of multiple drainage manifolds 9 are connected to an outlet pipe 10. The outlet pipe 10 is an integrated multi-channel manifold structure. The manifold structure has several independent channels corresponding to each set of drainage manifolds 9. A sanitary multi-way plug valve is integrated within the manifold structure. The valve core of the multi-way plug valve has a guide channel that rotates with the valve core to align with the target channel, enabling communication between the selected channel and the main outlet. Other misaligned channels remain isolated. An annular sealing ring is provided between the valve core and the valve body of the multi-way plug valve. Both the manifold structure and the plug valve body are made of 316L stainless steel. The inner wall is polished and has a rounded transition structure. Multiple sets of liquid inlet pipes 4 are equipped with check valves, and each set of liquid outlet pipes 9 is equipped with a controllable switch valve between the liquid outlet pipe 10 and the controllable switch valve is a ball valve. The liquid outlet pipe 10 is equipped with a ball valve with check function. Multiple sets of liquid baffles 8 are equipped with anti-corrosion sealing strips between multiple sets of mounting grooves 5. The outer wall of the fixed column 6 has a groove that fits with the liquid baffles 8, and multiple sets of liquid baffles 8 are equipped with anti-corrosion sealing strips between the grooves. Multiple sets of liquid inlet pipes 4 are connected to the upper cover plate 7 by flanges. The lower end face of the upper cover plate 7 is equipped with anti-corrosion sealing strips at the connection between it and the multiple sets of liquid baffles 8. Each set of observation windows 2 is located between two adjacent sets of liquid baffles 8, and each set of observation windows 2 has a set of scale lines on one side. Multiple sets of liquid outlet pipes 9 are connected to the bottom of the cylindrical body 1 by flanges. The bottom of the cylindrical body 1 is provided with a liquid outlet channel, which is located between two adjacent sets of liquid separators 8 to enable independent extraction of the drug solution in each storage chamber. A drain pipe 9 is provided outside the liquid outlet channel, guiding the drug solution to the liquid outlet pipe 10. The liquid outlet pipe 10 adopts an integrated multi-channel manifold structure, with several independent branch channels inside, each branch channel connected to the corresponding drain pipe 9. A sanitary multi-channel stopcock valve is integrated inside the liquid outlet pipe 10. The valve body of the stopcock valve is entirely embedded in the manifold body, and the valve core is a one-piece multi-channel stopcock with guide channels corresponding to the branch channels. When the operator rotates the handle on the stopcock valve, the guide channels on the valve core align with the target branch channel, thus connecting that branch to the main liquid outlet; other misaligned branches remain isolated, achieving selective control of independent liquid outlet from each storage chamber. To ensure reliable sealing, an annular sealing ring is provided between the outer surface of the plug valve core and the inner wall of the valve body. The sealing ring material is PTFE or EPDM, which can meet the requirements for sanitary use while being corrosion resistant. The plug valve core is equipped with a position indicator and a positioning locking mechanism to indicate the rotation angle of the valve core and the connected channel, and to prevent accidental operation. To meet cleaning needs, both the manifold body and the inner wall of the plug valve are made of 316L stainless steel with a polished surface and rounded transitions on the inner wall, without any right angles or dead corners. When fully open, the stopcock valve forms a continuous, smooth flow channel that connects to the main outlet, allowing the cleaning fluid to cover all channels inside the manifold body during CIP cleaning, preventing residue. Each inlet manifold 4 is equipped with a check valve to ensure that no backflow occurs during drug storage, enhancing the system's safety and reliability. Simultaneously, multiple drain manifolds 9 are also equipped with check valves to effectively prevent backflow of the drug into the storage chamber during extraction, further ensuring the unidirectional nature of drug extraction. When it is necessary to drain the drug from a specific storage chamber, the operator rotates the stopcock valve handle to the corresponding channel position. At this time, the guide channel within the stopcock valve core connects to the drain manifold 9 corresponding to that storage chamber, allowing the drug to flow into the manifold body through this channel and then be discharged from the main outlet of the outlet pipe 10. Other unselected branches remain closed due to the isolation effect of the valve core, thus preventing liquid cross-flow between the storage chambers. When performing CIP cleaning, the stopcock can be turned to the cleaning channel position or kept fully open. The cleaning fluid circulates through the manifold and the stopcock flow channel, ensuring no residue inside and meeting the requirements for pharmaceutical and food-grade use. Corrosion-resistant sealing strips are used between multiple sets of diaphragm plates 8 and multiple sets of mounting grooves 5, effectively preventing the mixing of medicine liquid between adjacent storage chambers. The corrosion-resistant sealing strips reduce the risk of material corrosion and extend the service life of the equipment. At the same time, the outer wall of the fixed column 6 is designed with a groove that fits with the diaphragm plate 8, enhancing the stability of the diaphragm plate 8 in the cylindrical body 1, thereby preventing leakage of medicine liquid during storage.Regarding the design of the observation window 2, it is positioned between two adjacent sets of liquid-separating plates 8, providing a direct, real-time observation of the condition in each liquid storage chamber, allowing operators to easily monitor the liquid level in each chamber. Each observation window 2 has corresponding graduation lines for accurate liquid level reading, ensuring timely replenishment and management of the liquid. Multiple inlet pipes 4 are connected to the upper cover plate 7 via flanges, ensuring a robust and airtight connection. Simultaneously, the anti-corrosion sealing strip at the connection point between the lower end of the upper cover plate 7 and the multiple sets of liquid-separating plates 8 further enhances the overall leak-proof performance, ensuring the safe storage of the liquid.
