[0002] In the pharmaceutical industry, solution preparation is a crucial step, involving the mixing of various drugs in specific proportions to form the desired final solution. Traditional solution preparation equipment typically consists of simple containers and stirring devices, which to some extent meet basic requirements. However, as the pharmaceutical industry's demands for precision and efficiency increase, traditional equipment has gradually revealed numerous problems. In recent years, the industry has been continuously exploring more intelligent and precise solution preparation systems. These efforts have significantly improved the quality control level of drug production. However, overall, the market still lacks ideal solution preparation tools that fully meet the high standards of modern pharmaceutical manufacturing.

[0003] Currently, commonly used liquid preparation tanks mainly include two types: open structure and closed structure. The advantages of open structure are simple design, low cost, and easy cleaning and maintenance; however, it also has the problems of high risk of contamination and difficulty in ensuring a sterile environment. While closed structure can effectively avoid external interference and thus better maintain cleanliness, it is expensive and complex to maintain. In addition, some manufacturers use products with automatic control systems to improve the ease of operation. These products achieve automatic adjustment by integrating sensors to monitor parameters such as temperature and pressure.

[0004] Existing liquid preparation tanks suffer from poor hardware compatibility, leading to difficulties in debugging, and their unfriendly software interfaces result in a steep learning curve for ordinary employees. Regardless of the type of solution, there are certain limitations that need to be improved and optimized. They either cannot ensure good hygiene conditions or rely too much on high cost investment to achieve full functionality. At the same time, they also face the problem of insufficient flexibility in use. Therefore, a liquid preparation tank is proposed to solve the above problems. Utility Model Content

[0012] As a further description of the above technical solution:

[0013] The bottom end of the motor is fixedly connected to the top end of the tank, and the scraper is in contact with the inside of the tank.

[0014] Furthermore, the tank provides support for the motor, while the scraper scrapes away any adhering substances inside the tank, making cleaning easier.

[0015] As a further description of the above technical solution:

A limiting block is fixedly connected to the outside of the sliding cylinder. A sealing gasket is fixedly connected inside the fixing port. A limiting groove is opened inside the fixing port. The outside of the limiting block is slidably connected to the inside of the limiting groove.

[0017] Furthermore, the mounting plate is used to connect the regulating valve and the fixed port. The sliding cylinder slides inside the fixed cylinder through the limiting component, thereby restricting the limiting block inside the limiting groove, thus ensuring the stability of the entire docking and facilitating disassembly.

[0018] As a further description of the above technical solution:

[0019] The top end of the fixed cylinder contacts the bottom end of the sealing gasket, and a connecting pipe is fixedly connected to the bottom end of the sliding cylinder;

[0020] Furthermore, the contact between the fixed cylinder and the sealing gasket ensures the sealing of the connection between the connecting pipe and the regulating valve.

The use of scrapers makes it easy to clean the inner wall of the tank.

[0032] 2. In this invention, during docking, the fixed cylinder is slid into the fixed opening, and the limiting block slides within the limiting groove. When the limiting block touches the inner wall of the limiting groove, the connecting pipe is rotated to move the limiting block laterally. After the rotation ends and the control is released, the elastic potential energy of the telescopic spring pushes the sliding cylinder, causing the limiting block to lock into the limiting groove. The top of the fixed cylinder tightly adheres to the sealing gasket, completing the sealed docking.

[0039] 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.

[0040] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a liquid mixing tank, comprising a tank body 1, an internal stirring mechanism 2, a feed inlet 4 at the top of the tank body 1, a touch screen 6 fixedly connected to the outside of the tank body 1, a regulating valve 5 fixedly connected to the bottom of the tank body 1, and an insulation layer 3 fixedly connected to the inside of the tank body 1. A docking mechanism 7 is provided at the bottom of the regulating valve 5. The tank body 1, as the main structure of the liquid mixing tank, provides space for the mixing and storage of materials. The insulation layer 3 inside the tank body 1 can effectively reduce heat loss or transfer, maintain the relative stability of the temperature inside the tank, ensure that the liquid mixing process is carried out under suitable temperature conditions, and avoid adverse effects on the properties of materials and the liquid mixing effect due to temperature fluctuations.

[0041] Specifically, for use in the pharmaceutical field, this liquid preparation tank consists of five main parts: tank body 1, inlet, feed port 4, stirring mechanism 2, and control system. These components work closely together to form a complete working system. When preparation begins, the feed port is first opened to add a predetermined amount of base solvent. Subsequently, various excipients are added according to the formula. During this process, the stirring mechanism 2 is activated to quickly mix the two and reduce the occurrence of excessively high local concentrations. At the same time, the built-in sensor network continuously collects the current environmental conditions, including but not limited to key indicators such as temperature, humidity, pH value, and dissolved oxygen content. The obtained values ​​are fed back to the central processor for further processing and calculation to determine whether the deviation from the preset threshold is detected. Once an abnormality is detected, an alarm is immediately issued to prompt corrective measures to be taken until the situation returns to normal. The entire process is strictly implemented in accordance with GMP standards to prevent any violations from endangering product quality.

[0042] The stirring mechanism 2 includes a rotating column 202, which is rotatably connected to the inside of the tank 1. A motor 201 is fixedly connected to the top of the rotating column 202. A stirring blade 203 is fixedly connected to the outside of the rotating column 202. A scraping assembly 204 is provided on the outside of the rotating column 202. The scraping assembly 204 includes two connecting columns 2041, which are fixedly connected to the outside of the rotating column 202. A scraper 2042 is fixedly connected to the side of the two connecting columns 2041 away from the rotating column 202. The motor 201... The bottom end of 1 is fixedly connected to the top of the tank body 1. The scraper 2042 is in contact with the inside of the tank body 1. When the preparation begins, the feed port 4 is opened first and a predetermined amount of basic solvent is added. Then, various auxiliary materials are added one after another according to the formula. At this time, the stirring mechanism 2 is started. The motor 201 drives the rotating column 202 to rotate. The rotating column 202 then drives the stirring blade 203 to rotate. The stirring blade 203 can effectively stir the materials in the tank, so that the basic solvent and auxiliary materials can be quickly mixed, reducing the occurrence of local high concentration, and improving the uniformity and mixing effect of the solution.

[0043] Meanwhile, the scraper 2042 of the scraping component 204 moves with the rotation of the rotating column 202, which can promptly scrape off the material adhering to the inner wall of the tank 1, preventing the material from accumulating on the tank wall, ensuring the quality of the solution preparation, and avoiding the impact of material residue on the tank wall on the subsequent solution preparation process. The touch screen 6 is fixedly connected to the outside of the tank 1. The operator can conveniently input various solution preparation parameters through the touch screen 6, such as the amount of basic solvent and auxiliary materials added, stirring time, temperature setting, etc. At the same time, the touch screen 6 can also display the current environmental conditions collected by the built-in sensor network of the tank 1 in real time, including but not limited to key indicators such as temperature, humidity, pH value, and dissolved oxygen content. The operator can intuitively understand the various parameters in the solution preparation process. Once an abnormality is found, corrective measures can be taken in time to ensure that the entire solution preparation process is strictly implemented in accordance with GMP standards and to prevent any violations from endangering product quality.

[0044] During solution preparation, the inlet 4 is opened to add the base solvent and auxiliary materials. The stirring mechanism 2 is then activated, and the motor 201 drives the rotating column 202 to rotate the stirring blades 203, enabling the materials to quickly blend. This significantly reduces the phenomenon of excessively high local concentrations and greatly improves the uniformity and mixing effect of the solution. At the same time, the scraper 2042 moves with the rotating column 202 to promptly scrape off the material on the tank wall, effectively preventing accumulation and ensuring the quality of the solution preparation. This avoids residues affecting subsequent solution preparation. The touch screen 6 outside the tank 1 allows operators to conveniently input solution preparation parameters and displays key indicators of the tank environment in real time, facilitating a direct understanding of the solution preparation status, timely correction of abnormalities, and ensuring that the solution preparation process strictly adheres to GMP standards, guaranteeing stable and reliable product quality.

[0045] Reference Figure 1 , Figure 3 and Figure 4The docking mechanism 7 includes a mounting plate 701. The top of the mounting plate 701 is firmly fixed to the bottom of the regulating valve 5, providing stable support for the other components of the docking mechanism 7. The bottom of the mounting plate 701 is fixedly connected to a cleverly designed and appropriately sized fixing port 702, providing a precise foundation for the connection of subsequent components. A smoothly movable fixing cylinder 703 is slidably connected inside the fixing port 702. The fixing cylinder 703 is in close cooperation with the internally slidably connected sliding cylinder 704. The two can move flexibly relative to each other and withstand a certain amount of external force, ensuring the reliability of the connection. The limiting component 709 set at the top of the sliding cylinder 704 is crucial, ensuring that it can... After connection, it effectively prevents the sliding cylinder 704 from moving accidentally and ensures a stable connection. The limiting block 705, which is fixedly connected to the outside of the sliding cylinder 704, is carefully designed in shape and size. The limiting block 705 slides smoothly and stably in the limiting groove 706. It can accurately guide the installation and positioning of the connecting pipe 708 during docking. When the top of the fixed cylinder 703 contacts the bottom of the sealing gasket 707, it will press the sealing gasket 707 tightly. The high-quality sealing material used in the sealing gasket 707 further enhances the sealing effect with its good elasticity, preventing liquid leakage. The connecting pipe 708, which is fixedly connected to the bottom of the sliding cylinder 704, is used to connect to external pipes or equipment to realize the discharge of liquid in the liquid tank.

[0046] Specifically, the mounting plate 701 is securely connected to the bottom of the regulating valve 5, providing support for the docking mechanism 7. The sliding connection between the fixed port 702 and the fixed cylinder 703, and between the fixed cylinder 703 and the sliding cylinder 704, is flexible and reliable. The limiting block 705 and the limiting groove 706 are precisely matched.

[0047] The telescopic column 7091 in the limiting assembly 709 has its top end fixed inside the fixed cylinder 703. It not only provides support for the telescopic spring 7092 sleeved on the outside, but also plays a guiding role. The top end of the telescopic spring 7092 is fixed inside the fixed cylinder 703, and its bottom end is connected to the top end of the sliding cylinder 704. Working together with the telescopic column 7091, it plays the role of accumulating and releasing elastic potential energy during the docking process, which helps to realize the quick installation and disassembly of the connecting pipe 708. The bottom end of the telescopic column 7091 is fixedly connected to the top end of the sliding cylinder 704, which ensures the structural stability of the entire limiting assembly 709 and enables the docking mechanism 7 to operate reliably. The bottom end of the tank 1 has a discharge port, which cooperates with the docking mechanism 7 to realize the smooth discharge of liquid.

[0048] Specifically, the mounting plate 701 is securely connected to the bottom of the regulating valve 5, providing support for the docking mechanism 7. The sliding connection between the fixed port 702 and the fixed cylinder 703, and between the fixed cylinder 703 and the sliding cylinder 704, is flexible and reliable. The limiting block 705 and the limiting groove 706 are precisely matched. Combined with the limiting assembly 709 consisting of the telescopic column 7091 and the telescopic spring 7092, during docking, the limiting block 705 slides along the limiting groove 706, and the telescopic spring 7092 accumulates elastic potential energy. After rotating to the correct position, the elastic potential energy is released to push the sliding cylinder 704, thus stabilizing the limiting block 705. The limiting and fixing cylinder 703 presses the sealing gasket 707 to achieve a quick and tight connection, effectively preventing liquid leakage. During disassembly, pushing and rotating the connecting pipe 708 will disengage the limiting block 705 from the limiting groove 706, completing the quick disassembly. The sealing gasket 707 is made of high-quality material, enhancing the sealing effect. The connecting pipe 708 is used to connect to external equipment to achieve liquid discharge. The entire docking mechanism 7 cooperates with the bottom outlet of the tank 1, ensuring reliable operation and providing significant advantages such as quick docking, strong sealing, and easy disassembly and maintenance, effectively ensuring the normal operation of the liquid preparation tank.

[0049] Working principle: When preparation begins, the feed inlet is first opened and the predetermined amount of base solvent is added. Then, various auxiliary materials are added successively according to the formula. During this process, the stirring mechanism 2 is activated to quickly mix the two and reduce the occurrence of excessively high local concentrations. At the same time, the built-in sensor network of the tank 1 continuously collects the current environmental conditions, including but not limited to key indicators such as temperature, humidity, pH value, and dissolved oxygen content. The obtained values ​​are fed back to the central processor for further processing and calculation to determine whether they deviate from the preset threshold. Once an abnormality is detected, an alarm is immediately issued to prompt corrective measures to be taken until the situation returns to normal. The entire process is strictly implemented in accordance with GMP standards to prevent any violations that may endanger product quality.

[0050] When the operator needs to connect the connecting pipe 708 and the regulating valve 5, the outer part of the fixed cylinder 703 is slid into the interior of the fixed port 702. Simultaneously, the limiting block 705 on the outside of the sliding cylinder 704 slides inside the limiting groove 706. When the limiting block 705 contacts the inner wall of the limiting groove 706, the connecting pipe 708 is rotated, causing the limiting block 705 to move laterally within the limiting groove 706. After rotation, the operator releases control of the connecting pipe 708, at which point the telescopic spring 7092 accumulates. The elastic potential energy will push the sliding cylinder 704 to slide outwards from the fixed cylinder 703, thereby restricting the limiting block 705 inside the limiting groove 706. The top of the fixed cylinder 703 will be tightly attached to the outside of the sealing gasket 707, thereby sealing the connecting pipe 708 with the mounting plate 701. By pushing the connecting pipe 708 and then rotating the connecting pipe 708, the limiting groove 706 can be released from the restriction of the limiting block 705. At this time, the connecting pipe 708 can be disassembled, completing the quick-release assembly and disassembly of the connecting pipe 708.

[0051] 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.
