Abstract
Description

[0002] In pharmaceutical production, alcohol precipitation is a crucial step, aiming to separate and purify the active ingredients through specific processes. However, for certain substances, cooling water is typically added to the precipitation tank to maintain a low temperature for optimal results. In practice, the temperature fluctuates drastically at the cooling water inlet, causing crystallization of some components in the pharmaceutical solution. These crystals adhere to the inner wall of the precipitation tank. Over time, the accumulation of crystals gradually reduces the effective volume of the tank, affecting the efficiency and effectiveness of the precipitation process. Furthermore, the crystals can impede flow within the tank, potentially impacting the quality of the pharmaceutical solution and subsequent processing steps. In addition, cleaning these crystals requires significant manpower and time, increasing production costs and extending the production cycle. Utility Model Content

[0041] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0042] like Figures 1-3As shown, an alcohol precipitation tank for pharmaceutical solutions is provided in one embodiment of this disclosure. The tank includes an inner tank 1 with a processing chamber 100. The processing chamber 100 has a pharmaceutical solution inlet 101, a dispensing port 102, a drain port 103, and a cold source inlet 104. A stirring shaft 2 is rotatably disposed within the processing chamber 100. A first stirring member 3 is disposed on the stirring shaft 2, located above the cold source inlet 104. One end of the first stirring member 3 has a scraper 301, which is configured to slide against the inner wall of the processing chamber 100 after being rotated by the first stirring member 3.
[0043] In this embodiment, the processing chamber 100 of the inner tank 1 is used for alcohol precipitation of the medicinal liquid. The medicinal liquid enters from the medicinal liquid inlet 101. After processing, the finished medicinal liquid can be taken out from the medicine outlet 102, and the residual liquid is discharged from the drain outlet 103. The cold source enters from the cold source inlet 104. The stirring shaft 2 rotates in the processing chamber 100 under the drive of an external drive device. The first stirring element 3 is installed on the stirring shaft 2 and is located above the cold source inlet 104. During operation, when the stirring shaft 2 rotates, it drives the first stirring element 3 to rotate. Due to the scraper 301 at one end of the first stirring element 3 sliding and abutting against the inner wall of the processing chamber 100 during rotation, this structural action brings significant beneficial effects: First, the stirring action of the first stirring element 3 can make the medicinal liquid more uniformly mixed in the processing chamber 100, improving the effect and efficiency of alcohol precipitation. Secondly, the scraper 301 can promptly remove crystals formed near the cold source inlet 104 due to temperature changes, preventing crystals from adhering to and accumulating on the inner wall, thereby maintaining the effective volume of the processing chamber 100, ensuring smooth flow of the liquid medicine, and reducing the impact on the quality of the liquid medicine. At the same time, the timely removal of crystals reduces the difficulty and cost of subsequent cleaning, saves manpower and time, and improves production efficiency.
[0044] In some examples, a second stirring element 4 is also included, which is disposed on the stirring shaft 2 and located above the first stirring element 3; the two ends of the first guide vane 5 are respectively disposed on the first stirring element 3 and the second stirring element 4, and the first guide vane 5 is configured to provide an upward or downward force on the liquid flow in the processing chamber 100 after being driven to rotate by the first stirring element 3 and the second stirring element 4.
[0045] In this embodiment, when the stirring shaft 2 rotates in one direction, the first stirring element 3 and the second stirring element 4 drive the first guide vane 5 to rotate. Under this operating condition, the first guide vane 5 can immediately gather the cold source entering the processing chamber 100 from the cold source inlet 104 to the center of the processing chamber 100 and transport it upwards, moving it away from the cold source inlet 104. This structural action brings significant beneficial effects: First, it avoids excessive accumulation of the cold source near the cold source inlet 104, making the temperature distribution within the processing chamber 100 more uniform, which is beneficial for improving the effect and consistency of alcohol precipitation. Second, it reduces the rapid formation of crystals near the cold source inlet 104 due to cold source accumulation, reducing the risk of crystal adhesion. Furthermore, rapidly dispersing the cold source to the center of the processing chamber 100 and transporting it upwards helps promote the overall mixing and reaction of the drug solution, improving the efficiency and quality of alcohol precipitation.
[0046] In some examples, the liquid inlet 101 and the dispensing port 102 are located at the top of the processing chamber 100, the drain port 103 is located at the bottom of the processing chamber 100, the cold source inlet 104 is located on the side wall of the processing chamber 100, and the processing chamber 100 also has a heat source inlet 105, which is located on the side wall of the processing chamber 100 and is located on the side of the cold source inlet 104 away from the drain port 103.
[0047] In this embodiment, the two ends of the first guide vane 5 are respectively connected to the first stirring member 3 and the second stirring member 4. When the stirring shaft 2 rotates in one direction, the first guide vane 5 can immediately gather the cold source entering the processing chamber 100 from the cold source inlet 104 to the center of the processing chamber 100 and transport it upward, moving it away from the cold source inlet 104. When the stirring shaft 2 rotates in the other direction, the first guide vane 5 can quickly disperse the heat source entering from the heat source inlet 105 into the processing chamber 100, promoting uniform heat distribution. The cold source inlet 104 is located near the bottom, and the heat source inlet 105 is located above, based on the following considerations: When adjusting the temperature, the density of the low-temperature cold source is usually higher. After entering the processing chamber 100 from the lower cold source inlet 104, it will naturally flow towards the bottom of the processing chamber 100. At this time, the first guide vane 5 transports the cold source upward, avoiding excessive accumulation of the cold source at the bottom and making the temperature distribution more uniform. The heat source has a relatively low density. After being input from the upper heat source inlet 105, it is dispersed by the first guide vane 5, preferentially heating the liquid medicine in the upper part of the treatment chamber 100, promoting uniform heat diffusion. This layout makes the temperature distribution within the treatment chamber 100 more reasonable and uniform, avoiding localized excessively high or low temperatures, and improving the effect and quality of alcohol precipitation. For example, in some alcohol precipitation processes that require initial low-temperature treatment followed by heating, this input position of the cold and heat sources, along with the function of the first guide vane 5, can precisely meet the process requirements, ensuring that the liquid medicine receives suitable temperature conditions at different stages, thereby optimizing the alcohol precipitation effect and guaranteeing the stability and consistency of product quality.
[0048] In some examples, the first stirring element 3 and the second stirring element 4 have the same structure and are parallel to each other. The first stirring element 3 has a first strip-shaped guide groove 302 along the length direction, and the second stirring element 4 has a second strip-shaped guide groove 401 along the length direction. The first strip-shaped guide groove 302 and the second strip-shaped guide groove 401 are staggered in the length direction. The first stirring element 3 also includes a first slider 6, which is slidably disposed in the first strip-shaped guide groove 302. The second slider 7 is slidably disposed in the second strip-shaped guide groove 401. After sliding, the first slider 6 and the second slider 7 move closer to each other or further away in the horizontal direction. One end of the first swing rod 8 is hinged to the first slider 6. One end of the second swing rod 9 is hinged to the second slider 7. The other ends of the first swing rod 8 and the second swing rod 9 are slidably disposed at the upper and lower ends of the second guide blade 10, respectively. The width direction of the second guide blade 10 is set at an angle to the length direction of the first swing rod 8.
[0049] In this embodiment, when the first stirring member 3 and the second stirring member 4 begin to rotate, the upper or lower end of the second guide vane 10 will slide accordingly depending on the direction of rotation. For example, when rotating in one direction, the second guide vane 10 forms a spirally ascending vane; when rotating in another direction, the second guide vane 10 forms a spirally descending vane. Furthermore, the guiding direction of the second guide vane 10 is opposite to that of the first guide vane 5. First, because the guiding directions of the second guide vane 10 and the first guide vane 5 are opposite, a smooth circulation path can be formed inside the processing chamber 100, promoting thorough mixing and flow of the liquid, and avoiding local accumulation and uneven distribution of the liquid. Second, as the rotation speed of the stirring member increases, the circulation efficiency also increases, further enhancing the alcohol precipitation effect and processing efficiency of the liquid. Whether in low-temperature cooling or high-temperature heating processes, it can ensure that the liquid quickly reaches the required temperature and processing state, improving the stability and reliability of the entire alcohol precipitation process. With rapid stirring, the liquid can complete the alcohol precipitation process more quickly, shortening the production cycle, improving production efficiency, and ensuring the quality and consistency of the liquid treatment.
[0050] In some examples, a first elastic element 11 is also included, one end of which acts on the first slider 6 and the other end of which acts on the side wall of the first strip guide groove 302, providing a force away from the side wall of the first strip guide groove 302; a second elastic element 12 is applied at one end to the second slider 7 and at the other end to the side wall of the second strip guide groove 401, providing a force away from the side wall of the second strip guide groove 401, and the first elastic element 11 and the second elastic element 12 act in opposite directions.
[0051] In this embodiment, when the first stirring member 3 and the second stirring member 4 rotate, the first slider 6 and the second slider 7 slide within the first strip guide groove 302 and the second strip guide groove 401, respectively. Due to the action of the first elastic member 11 and the second elastic member 12, the sliding of the first slider 6 and the second slider 7 has a certain elastic buffering and restoring force. First, the first elastic member 11 and the second elastic member 12 can increase the stability of the sliding of the first slider 6 and the second slider 7, reduce component damage caused by severe vibration or impact, and extend the service life of the equipment. Second, the elastic members enable the oscillation and position change of the second guide vane 10 to be more flexible and adaptive, allowing for fine-tuning according to the flow and stirring conditions of the liquid, further improving the stirring and guiding effect. Furthermore, the restoring force provided by the elastic members helps the second guide vane 10 to quickly return to its initial state or adjust to a suitable working position when stirring stops or the speed changes, preparing for the next stirring operation and improving the working efficiency and reliability of the equipment.
[0052] In some examples, a liquid extraction tube 13 is also included, which extends into the processing chamber 100 and has a liquid extraction channel 1301 that connects the processing chamber 100 and the drug extraction port 102.
[0053] In this embodiment, the liquid extraction tube 13 makes the drug extraction process more centralized and orderly, enabling accurate extraction of the drug solution from a specific location within the processing chamber 100, ensuring the quality and representativeness of the extracted solution. Secondly, extraction via the liquid extraction tube 13 reduces fluctuations and disturbances in the drug solution during extraction, avoiding unnecessary impact on the alcohol precipitation state of the drug solution within the processing chamber 100, and ensuring the stability of the overall processing effect. Furthermore, the existence of the liquid extraction channel 1301 effectively prevents external impurities from contaminating the drug solution during extraction, ensuring the purity and safety of the solution.
[0054] In some examples, a third agitator 14 is also included, which is located above the second agitator 4 and below the lowest point of the liquid intake channel 1301.
[0055] In this embodiment, when the stirring shaft 2 rotates, the third stirring element 14 rotates accordingly. Firstly, this further enhances the stirring effect of the liquid in the upper part of the processing chamber 100, allowing the components in the liquid to mix more evenly near the inlet of the liquid collection channel 1301, thus improving the consistency of the quality of the collected liquid. Secondly, by stirring the upper liquid, any possible precipitation or stratification in the liquid is reduced, ensuring that the liquid taken from the liquid collection channel 1301 has stable quality. Furthermore, the presence of the third stirring element 14 promotes the overall circulation of the liquid within the processing chamber 100, making the alcohol precipitation treatment of the liquid more thorough and efficient.
[0056] In some examples, an outer tank 15 is also included, with an inner tank 1 disposed inside the outer tank 15, and an insulation interlayer 1501 is formed between the inner tank 1 and the outer tank 15.
[0057] In this embodiment, the insulation jacket 1501 effectively reduces heat exchange between the inner tank 1 and the external environment. When the processing chamber needs to maintain a low or high temperature, the insulation jacket 1501 can prevent the ingress of external heat or the loss of internal heat, thereby maintaining a stable temperature within the processing chamber. This helps reduce energy consumption, improve the accuracy and efficiency of temperature control, and ensure the stability and consistency of the alcohol precipitation process. Simultaneously, the good insulation effect can also reduce the potential impact of temperature fluctuations on the quality of the drug solution, improving product quality and reliability.
[0058] In some examples, there are several first stirring elements 3, second stirring elements 4 and third stirring elements 14 arranged circumferentially on the stirring shaft 2.
[0059] In this embodiment, the structure of multiple circumferentially arranged agitators brings significant benefits. First, it greatly enhances the coverage and intensity of agitation, ensuring that the liquid is fully stirred and mixed throughout the treatment chamber 100, avoiding uneven treatment in certain areas. Second, the coordinated operation of multiple agitators allows for flexible agitation based on different liquid levels and treatment requirements, improving the adaptability of the alcohol precipitation tank to various treatment conditions. Third, the more uniform and efficient agitation shortens the alcohol precipitation time, increases production efficiency, and ensures the quality and consistency of the treated liquid.
[0060] In some examples, the first guide vane 5 is arranged in several circles.
[0061] In this embodiment, multiple circumferentially arranged first guide vanes 5 can more comprehensively and uniformly guide the liquid, resulting in a more stable and orderly flow state within the treatment chamber 100. Whether a cold or hot source is introduced, it can quickly and uniformly disperse or collect the liquid, ensuring a more uniform temperature throughout the treatment chamber 100 and improving the effectiveness and quality of the alcohol precipitation process. Simultaneously, this uniform flow guidance helps reduce localized eddies and turbulence in the liquid, lowering energy loss and improving equipment operating efficiency. Furthermore, the coordinated operation of multiple first guide vanes 5 enhances the control over the liquid flow, better adapting to different process requirements and liquid characteristics, thus improving the versatility and applicability of the alcohol precipitation tank.
