Description

TECHNICAL FIELD

[0001] The utility model relates to the field of medicament production equipment, especially to a medicament bottle vacuum defoaming device. BACKGROUND

[0002] In the medicament production process, medicament is often filled into medicament bottles, and in order to ensure the stability of the medicament, prolong the shelf life and prevent oxidation, the medicament bottles are subjected to vacuum treatment.

[0003] However, the vacuum process can cause the liquid pressure in the medicament bottle to drop sharply, thereby causing a large number of bubbles to be generated. If these bubbles cannot be eliminated in time and effectively, they will have many adverse effects. On the one hand, the bubbles occupy space in the bottle, making it difficult to accurately control the actual filling amount of the medicament, which directly affects the consistency of product quality; on the other hand, the long-term existence of the bubbles creates conditions for the contact between the medicament components and the outside air, accelerates the oxidation and deterioration process of the medicament, and also interferes with subsequent packaging operations such as labeling and boxing, reducing production efficiency.

[0004] Traditional defoaming methods, such as waiting for bubbles to naturally escape and simple mechanical stirring, not only consume time and effort, but also have poor treatment effect on small bubbles and bubbles in high-viscosity medicaments, and cannot meet the high-speed and high-precision production requirements of today's medicament industry. Therefore, there is an urgent need for a defoaming device specifically for medicament bottles in a vacuum state to solve the above problems. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a medicament bottle vacuum defoaming device to effectively eliminate bubbles generated in the medicament bottle under a vacuum environment and improve the quality and efficiency of medicament production.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A medicament bottle vacuum defoaming device, comprising a medicament bottle, a vacuum generating mechanism and a defoaming mechanism; the vacuum generating mechanism is arranged on the top of the medicament bottle and is used to create a vacuum environment in the medicament bottle; the defoaming mechanism is arranged in the vacuum generating mechanism and is used to promote the rupture of bubbles in the medicament bottle under a vacuum;

[0008] The vacuum generating mechanism comprises a vacuum assembly and a vacuum box body;

[0009] The vacuum box body is arranged on the top of the medicament bottle, and the vacuum box body is provided with an air extraction hole,

[0010] The vacuum assembly is connected to the vacuum box body through the air extraction hole;

[0011] The defoaming mechanism comprises a defoaming cylinder;

[0012] The defoaming cylinder is arranged in the vacuum box body, and an opening is arranged at the bottom of the defoaming cylinder and faces the top of the medicine bottle.

[0013] The outer wall of the defoaming cylinder is provided with a defoaming hole, which is arranged close to the bottom of the defoaming cylinder and communicates with the air suction hole.

[0014] The above technical scheme has the following beneficial effects: through the ingenious design, the components of the device work together to achieve high defoaming efficiency; the vacuum generating mechanism is located at the top of the medicine bottle, wherein the vacuum box body is connected with the medicine bottle and is provided with an air suction hole, which cooperates with the vacuum assembly to quickly suck out air and create a vacuum environment in the medicine bottle, thereby creating conditions for defoaming; the defoaming cylinder of the defoaming mechanism is arranged in the vacuum box body, and the opening at the bottom of the defoaming cylinder is aligned with the top of the medicine bottle, which can guide the airflow to contact the liquid in the medicine bottle; the defoaming hole on the outer wall of the defoaming cylinder close to the bottom communicates with the air suction hole, and during the vacuum suction process, a pressure difference is generated in the medicine bottle, which promotes the movement of bubbles to the defoaming hole and breaks the bubbles, thereby significantly promoting the breaking of bubbles when the medicine bottle is in a vacuum state, effectively improving the quality of the medicine, and ensuring the safety and stability of the drug effect.

[0015] Preferably, the vacuum assembly comprises a vacuum pump, a vacuum tube and a vacuum head; the vacuum head is arranged in the air suction hole and is in sealed connection with the air suction hole; the vacuum pump is in sealed connection with the vacuum head through the vacuum tube.

[0016] The above technical scheme has the following beneficial effects: by comprising a vacuum pump, a vacuum tube and a vacuum head, the vacuum head is installed in the air suction hole and is in sealed connection with the air suction hole, which ensures the sealing of the air suction process and avoids gas leakage, thereby laying a foundation for creating a stable vacuum environment; the vacuum pump serves as a power source and is closely connected with the vacuum head through the vacuum tube, and when it is started, it can efficiently suck out air from the medicine bottle through the vacuum head with stable and strong suction force, which cooperates with the vacuum box body and the defoaming mechanism to quickly create a required vacuum environment in the medicine bottle and accelerate the breaking of bubbles, and the precise sealed connection ensures the reliability of the entire vacuum generating system, thereby continuously and stably improving the defoaming effect in the medicine bottle and further ensuring the quality of the medicine and the safety and stability of the drug effect.

[0017] Preferably, a first vacuum cavity is arranged in the defoaming cylinder and is arranged close to the top of the medicine bottle.

[0018] The above technical solution offers the following advantages: By setting a first vacuum chamber near the top of the medicine bottle inside the defoaming cylinder, this design further optimizes the distribution of the vacuum environment. On one hand, the first vacuum chamber can create a stronger local negative pressure in the top area of ​​the medicine bottle. When the liquid inside the medicine bottle is under vacuum, the bubbles will enter this area first during their upward movement, experiencing a greater pressure difference, making the bubbles easier to break and accelerating the defoaming process. On the other hand, working in conjunction with the vacuum chamber, defoaming holes, and vacuum components, it strengthens the vacuum gradient of the entire device, making the gas suction path more reasonable. This not only ensures the rapid establishment and stable maintenance of the vacuum environment inside the medicine bottle but also promotes bubble breakage in a comprehensive and multi-layered manner, maximizing defoaming efficiency, ensuring superior medicine quality, safe and worry-free medication, and stable and long-lasting efficacy.

[0019] In a preferred embodiment, a second vacuum chamber is provided between the outer wall of the defoaming cylinder and the inner wall of the vacuum chamber, and the second vacuum chamber is connected to the air extraction hole and the defoaming hole.

[0020] The above technical solution has the following beneficial effects: By setting a second vacuum chamber between the outer wall of the defoaming cylinder and the inner wall of the vacuum chamber, which is connected to the air extraction hole and the defoaming hole, the range of vacuum action is greatly expanded. On the one hand, it opens up a new channel for gas flow, making the air extraction process smoother and more efficient, helping the vacuum environment to spread rapidly and evenly within the device, strengthening the overall vacuum effect, and accelerating the rising rate of bubbles in the medicine bottle. On the other hand, in conjunction with the first vacuum chamber, the vacuum chamber, and other components, a more complex and precise vacuum network is constructed, allowing bubbles to be driven by pressure differences from different directions under multiple negative pressures, causing them to gather and burst towards the defoaming hole, comprehensively improving the defoaming efficiency, effectively ensuring the purity of the medicine, ensuring the stable and reliable quality of the medicine, and firmly safeguarding the safety of medication use.

[0021] In a preferred embodiment, the number of defoaming holes is several, and the defoaming holes are connected to the first vacuum chamber and the second vacuum chamber.

[0022] The above technical solution has the following advantages: By increasing the number of defoaming holes and connecting them to the first and second vacuum chambers, the defoaming performance is optimized in many ways. Firstly, the numerous defoaming holes significantly increase the pathways for bubble escape, allowing bubbles in various parts of the medicine bottle to find an outlet nearby, avoiding bubble congestion and accelerating the defoaming process. Secondly, by connecting the first and second vacuum chambers, a comprehensive negative pressure drainage system is constructed. The vacuum suction in different areas is precisely applied to the bubbles through the defoaming holes. No matter where the bubbles are in the medicine bottle, they can be efficiently drawn to the defoaming holes and burst under the strong and balanced pressure difference.

[0023] In a preferred embodiment, the opening is provided with a first sealing gasket, which is adapted to the top of the medicine bottle.

[0024] The above technical solution has the following beneficial effects: In the vacuum defoaming device for medicine bottles, the first sealing gasket at the opening plays an important role. Located near the top of the medicine bottle, it firstly effectively enhances the sealing of the connection between the defoaming cylinder and the medicine bottle, preventing outside air from entering the medicine bottle and ensuring the stability of the created vacuum environment, thus avoiding any impact on the defoaming effect due to air leakage. Secondly, this sealing effect helps maintain the pressure difference inside the device, allowing air bubbles inside the medicine bottle to move and break more orderly towards the defoaming holes and other defoaming areas under a preset pressure environment in a vacuum state, ensuring the entire defoaming process proceeds smoothly as expected, thereby improving the reliability and efficiency of the device's defoaming process.

[0025] In a preferred embodiment, the bottom of the vacuum chamber is provided with a second sealing gasket, which is adapted to the outer surface of the medicine bottle.

[0026] The above technical solution has the following advantages: By setting a second sealing gasket at the bottom of the vacuum chamber, which is located on the outer surface of the reagent bottle, it can, on the one hand, tightly seal the connection between the vacuum chamber and the outer surface of the reagent bottle, preventing outside air from seeping into the reagent bottle from this part. This effectively maintains the carefully created vacuum environment inside the reagent bottle, ensuring that the vacuum degree is not disturbed by external factors, and creating favorable conditions for the continuous and stable implementation of defoaming work. On the other hand, by ensuring the sealing at this point, the overall pressure distribution inside the device is stabilized, allowing the bubbles in the reagent bottle to move towards the defoaming mechanism and break down in a predetermined manner under a stable and appropriate pressure difference, further improving the accuracy and efficiency of the entire device in defoaming.

[0027] In a preferred embodiment, the inner diameter of the air extraction hole is larger than the outer diameter of the defoaming hole.

[0028] The above technical solution has the following advantages: the larger inner diameter of the evacuation hole allows a larger amount of gas to be extracted per unit time, which can quickly reduce the gas pressure inside the medicine bottle and efficiently create a stable vacuum environment; while the relatively smaller outer diameter of the defoaming hole allows the bubbles to form a more concentrated and suitable pressure difference when they gather and burst, making the bubbles easier to break and accurately achieving the defoaming function.

[0029] In a preferred embodiment, the vacuum tube is L-shaped.

[0030] The above technical solution has the following advantages: The unique "L"-shaped bend changes the direction and state of gas flow, making it easier for liquid bubbles to separate from the gas when they pass through this bend due to the combined effects of gravity and airflow changes. The bubbles are less likely to continue smoothly along the pipe, thus preventing them from entering the vacuum pump. This protects the vacuum pump from damage such as liquid corrosion and blockage, extending its service life. On the other hand, by preventing bubbles from entering the vacuum pump, the stable operation of the pumping system is ensured, maintaining a good and stable vacuum environment creation capability, allowing the entire device to continuously and effectively perform its defoaming function.

[0044] The outer wall of the defoaming cylinder 31 is provided with a defoaming hole 312, which is located near the bottom of the defoaming cylinder 31 and is connected to the air extraction hole 221.

[0045] Vacuum generating mechanism 2 is located at the top of medicine bottle 1. Vacuum chamber 22 is connected to medicine bottle 1 and is equipped with air extraction port 221. In conjunction with vacuum component 21, it can quickly extract air and create a vacuum environment inside medicine bottle 1, thus creating conditions for defoaming. Defoaming mechanism 3 has defoaming cylinder 31 placed inside vacuum chamber 22. Its bottom opening 311 is aligned with the top of medicine bottle 1, which can guide airflow to contact the liquid inside medicine bottle 1. The defoaming hole 312 on its outer wall near the bottom is connected to the air extraction port 221. During vacuum suction, a pressure difference is generated inside medicine bottle 1, which causes bubbles to move towards the defoaming hole 312 and break. This significantly promotes the breakage of bubbles when medicine bottle 1 is in a vacuum state, effectively improving the quality of medicine and ensuring medication safety and stable efficacy.

[0046] In this embodiment, the vacuum assembly 21 includes: a vacuum pump, a vacuum tube 211, and a vacuum head 212;

[0047] The vacuum head 212 is located inside the air extraction port 221, and the vacuum head 212 is sealed to the air extraction port 221.

[0048] The vacuum pump is sealed to the vacuum head 212 via vacuum tube 211;

[0049] By using a vacuum assembly 21 consisting of a vacuum pump, a vacuum tube 211, and a vacuum head 212, with the vacuum head 212 installed inside and sealed to the air extraction port 221, the airtightness of the extraction process is ensured, preventing gas leakage and laying the foundation for creating a stable vacuum environment. The vacuum pump, as a power source, is tightly connected to the vacuum head 212 through the vacuum tube 211. When started, it can efficiently extract air from the medicine bottle 1 with a stable and strong suction force through the vacuum head 212. In conjunction with the vacuum chamber 22 and the defoaming mechanism 3, it can quickly create the required vacuum environment inside the medicine bottle 1, accelerating bubble breakage. On the other hand, the precise sealing connection ensures the reliability of the entire vacuum generation system, thereby continuously and stably improving the defoaming effect inside the medicine bottle, further ensuring the quality of the medicine and the safety and efficacy stability of the medication.

[0050] In this embodiment, the defoaming cylinder 31 is provided with a first vacuum chamber 313, which is located near the top of the medicine bottle 1;

[0051] By setting a first vacuum chamber 311 near the top of the medicine bottle 1 inside the defoaming cylinder 31, this design further optimizes the distribution of the vacuum environment. On the one hand, the first vacuum chamber 311 can create a stronger local negative pressure in the top area of ​​the medicine bottle 1. When the liquid in the medicine bottle 1 is under vacuum, the bubbles will enter this area first during their upward movement, and be subjected to a greater pressure difference, making the bubbles easier to break and accelerating the defoaming process. On the other hand, working in conjunction with the vacuum chamber 22, the defoaming hole 312, and the vacuum component 21, it strengthens the vacuum gradient of the entire device, making the gas suction path more reasonable. This not only ensures the rapid establishment and stable maintenance of the vacuum environment inside the medicine bottle 1, but also promotes bubble breakage in an all-round and multi-level manner, maximizing the defoaming efficiency, ensuring the quality of the medicine, safe use, and stable and long-lasting efficacy.

[0052] In this embodiment, a second vacuum chamber 314 is provided between the outer wall of the defoaming cylinder 31 and the inner wall of the vacuum chamber 22. The second vacuum chamber 314 is connected to the air extraction hole 221 and the defoaming hole 312.

[0053] By setting a second vacuum chamber 314 between the outer wall of the defoaming cylinder 31 and the inner wall of the vacuum chamber 22, and connecting it with the evacuation port 221 and the defoaming port 312, the range of vacuum action is greatly expanded. On the one hand, it opens up a new channel for gas flow, making the evacuation process smoother and more efficient, helping the vacuum environment to spread rapidly and evenly within the device, strengthening the overall vacuum effect, and accelerating the rising rate of bubbles in the medicine bottle 1. On the other hand, in conjunction with the first vacuum chamber 311, the vacuum chamber 22, and other components, a more complex and precise vacuum network is constructed, allowing bubbles to be driven by pressure differences from different directions under multiple negative pressures, causing them to gather and burst towards the defoaming port 312, comprehensively improving the defoaming efficiency, effectively ensuring the purity of the medicine, ensuring the stable and reliable quality of the medicine, and firmly safeguarding the safety of medication use.

[0054] In this embodiment, the number of defoaming holes 312 is several, and the defoaming holes 312 are connected to the first vacuum chamber 311 and the second vacuum chamber 314.

[0055] By incorporating a number of defoaming holes 312 and connecting them to the first vacuum chamber 311 and the second vacuum chamber 314, the defoaming performance is optimized in several ways. Firstly, the numerous defoaming holes 312 significantly increase the pathways for bubble escape, allowing bubbles in various parts of the medicine bottle 1 to find an outlet nearby, avoiding bubble congestion and accelerating the defoaming process. Secondly, by connecting the first and second vacuum chambers, a comprehensive negative pressure drainage system is constructed. The vacuum suction in different areas is precisely applied to the bubbles through the defoaming holes 312. No matter where the bubbles are in the medicine bottle 1, they can be efficiently drawn to the defoaming holes 312 and burst under the drive of a strong and balanced pressure difference.

[0056] In this embodiment, a first sealing gasket 4 is provided at the opening 311, and the first sealing gasket 4 is adapted to the top of the medicine bottle 1;

[0057] In the vacuum defoaming device for medicine bottles, the first sealing gasket 4 at the opening 311 plays a crucial role. Located near the top of the medicine bottle 1, it firstly enhances the sealing of the connection between the defoaming cylinder 31 and the medicine bottle 1, preventing outside air from entering the medicine bottle 1 and ensuring the stability of the created vacuum environment, thus avoiding the impact of air leakage on the defoaming effect. Secondly, this sealing effect helps maintain the pressure difference inside the device, allowing bubbles in the medicine bottle 1 to move and break more orderly towards the defoaming holes 312 and other defoaming areas under the preset pressure environment in a vacuum state, ensuring that the entire defoaming process proceeds smoothly as expected, thereby improving the reliability and efficiency of the device's defoaming process.

[0058] In this embodiment, a second sealing gasket 5 is provided at the bottom of the vacuum chamber 22, and the second sealing gasket 5 is adapted to the outer surface of the medicine bottle 1;

[0059] By setting a second sealing gasket 5 at the bottom of the vacuum chamber 22, which is located on the outer surface of the medicine bottle, it can, on the one hand, tightly seal the connection between the vacuum chamber 22 and the outer surface of the medicine bottle 1, preventing outside air from seeping into the medicine bottle 1 from this part, effectively maintaining the carefully created vacuum environment inside the medicine bottle 1, ensuring that the vacuum degree is not disturbed by external factors, and creating good conditions for the continuous and stable development of defoaming work; on the other hand, by ensuring the sealing at this point, the overall pressure distribution inside the device is stabilized, so that the bubbles in the medicine bottle 1 can move to the defoaming mechanism 6 and break under a stable and appropriate pressure difference in a predetermined manner, further improving the accuracy and efficiency of the entire device in defoaming.

[0060] In this embodiment, the inner diameter of the air extraction hole 221 is larger than the outer diameter of the defoaming hole 312;

[0061] The larger inner diameter of the evacuation port 221 allows a larger amount of gas to be extracted per unit time, which can quickly reduce the gas pressure inside the medicine bottle 1 and efficiently create a stable vacuum environment; while the relatively smaller outer diameter of the defoaming port 312 allows the bubbles to form a more concentrated and suitable pressure difference when they gather and break, making the bubbles easier to break and accurately achieving the defoaming function.

[0062] In this embodiment, the vacuum tube 211 is L-shaped;

[0063] The unique "L"-shaped bend alters the direction and state of gas flow. During the pumping process, when the liquid bubbles pass through this bend, the combined effects of gravity and airflow changes make it easier for them to separate from the gas. This prevents the bubbles from continuing smoothly along the pipe, thus avoiding their entry into the vacuum pump. This protects the vacuum pump from damage such as liquid corrosion and blockage, extending its service life. On the other hand, by preventing bubbles from entering the vacuum pump, the stable operation of the pumping system is ensured, maintaining a good and stable vacuum environment and enabling the entire device to continuously and effectively perform its defoaming function.

[0064] In this embodiment, defoaming protrusions may also be provided on the edge of the defoaming hole 312, and the defoaming protrusions are provided on the side of the first vacuum cavity 313;

[0065] The defoaming protrusions can physically puncture nearby bubbles. When a bubble moves to the vicinity of the defoaming hole 312, the defoaming protrusions will change the original flow trajectory of the bubble, causing it to deform and vibrate, thus disrupting the stability of the bubble and making it easier to break at the defoaming hole, which greatly improves the defoaming efficiency.
