Description

Technical Field

[0001] This utility model relates to the field of batching tank technology, specifically to a vacuum homogenizing batching tank. Background Technology

[0002] In the production process of soft capsules, the raw drug solution needs to be heated, dissolved, homogenized, and thoroughly mixed. The raw drug solution contains microbubbles, which can cause holes in the capsule shell later on, leading to leakage of the contents.

[0003] In traditional techniques, the original drug solution of soft capsules is usually stirred to cause microbubbles to aggregate into air bubbles, and then negative pressure is applied to make the air bubbles burst and be extracted. However, the stirring process often produces splashing drug droplets. These droplets splash into the exhaust port and flow into the vacuum pump, which can damage the internal structure of the vacuum pump (the water, viscous substances, and particulate matter in the drug droplets can cause corrosion, adhesion, and wear of the internal structure of the vacuum pump, respectively).

[0040] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0041] Reference Figures 1-2This embodiment provides a vacuum homogenizing mixing tank, including a first tank body 1, a water bath assembly 2, a mixing assembly 3, and a vacuum assembly 4. The first tank body 1 has a feed pipe 11 at its top, and the water bath assembly 2 is installed around the outer sidewall and bottom wall of the first tank body 1. The water bath assembly 2 is used to heat the first tank body 1 and its contents (i.e., the original drug solution for soft capsules), providing a gentle heating method that avoids the problem of drug denaturation caused by excessively high local temperatures. A closable cover is installed on the end face of the feed pipe 11 away from the first tank body 1. One end of the cover is rotatably connected to the feed pipe 11, and the other end is detachably connected to the feed pipe 11 (e.g., via a spring clip). A sealing ring is fitted around the edge of the cover. When the cover is closed, the sealing ring seals between the feed pipe 11 and the cover, preventing air leakage and ensuring that the pressure in the first tank body 1 can be smoothly reduced later.

[0042] Reference Figures 1-2 The water bath assembly 2 includes an outer shell 21, which is fitted around the outer periphery of the first tank 1. A receiving gap 22 is provided between the outer shell 21 and the first tank 1, and a heating fluid for water bath heating is provided within the receiving gap 22. The heating fluid is water. The edge of the outer shell 21 is sealed and fixedly connected to the outer wall of the first tank 1 (e.g., by bolts and sealing rings, or by welding) to prevent water leakage from the receiving gap 22.

[0043] Reference Figures 1-3 The water bath assembly 2 also includes a first water exchange pipe 23, a second water exchange pipe 24, an external water tank 25, and an external water pump 26. One end of the first water exchange pipe 23 is connected to the bottom of the receiving gap 22, and the other end is connected to the external water pump 26; the external water pump 26 is connected to the external water tank 25; one end of the second water exchange pipe 24 is connected to the top of the receiving gap 22, and the other end is connected to the external water tank 25; an electric heating element 27 is installed inside the receiving gap 22. A first ball valve 231 is installed in the middle of the first water exchange pipe 23. The user opens the first ball valve 231 and starts the external water pump 26, which pressurizes the heating fluid in the external water tank 25 into the receiving gap 22 until the receiving gap 22 is filled with heating fluid (excess heating fluid will overflow from the top of the receiving gap 22 and overflow into the external water tank 25 through the second water exchange pipe 24); then the electric heating tube 27 is started to heat the heating fluid (the heating fluid expands when heated, and excess heating fluid will overflow from the top of the receiving gap 22 and overflow into the external water tank 25 through the second water exchange pipe 24), and the heat is transferred to the soft capsule original medicine liquid through the first tank 1.

[0044] Reference Figure 3 The outer shell 21 is provided with an insulation layer 211 (such as polyurethane foam material) to reduce the heat loss of the heating fluid in the containment gap 22 and achieve energy saving effect.

[0045] Water nozzles are inserted and installed at the bottom and top of the outer casing 21, respectively. The inner end of the water nozzle is connected to the receiving gap 22. The first water replacement pipe 23 and the second water replacement pipe 24 are respectively connected to the two water nozzles, thereby realizing the connection between the first water replacement pipe 23 and the receiving gap 22, and the connection between the second water replacement pipe 24 and the receiving gap 22.

[0046] Reference Figure 3 The electric heating element 27 includes an L-shaped heating element 271 and a mounting portion 272 (for example, a sealed connection is achieved by bolts and a sealing ring); the heating element 271 is vertically inserted into the receiving gap 22, and the mounting portion 272 is horizontally inserted into the mounting hole of the outer casing 21 and sealed (for example, a connection by a clamp, bolts, and a sealing ring). The mounting portion 272 is made of an insulating material (e.g., ceramic); the heating element 271 includes a hollow insulating outer casing and a resistance wire inserted into the inner cavity of the insulating outer casing; an insulating layer (e.g., glass, ceramic, etc.) is filled between the insulating outer casing and the resistance wire, and the power supply wire 273 passes through the mounting portion 272 and is connected to the resistance wire.

[0047] Reference Figure 3 The electric heating element 27 is fixedly connected to the inner wall of the outer casing 21 (for example, the heating element 271 is fixedly connected to the inner wall of the outer casing 21 by pipe clamps and bolts), thereby preventing the electric heating element 27 from shaking under the impact of water flow, and thus preventing the installation part 272 from rotating and the connection position with the outer casing 21 from loosening and leaking water.

[0048] The electric heating element 27 is connected to the external power supply via the power supply wire 273, and the external water pump 26 is connected to the external power supply via the wire.

[0049] Reference Figure 4 The mixing assembly 3 includes a drive motor 31, a rotating shaft 32, stirring blades 33, and a homogenizer 34. The drive motor 31 is located on the top surface of the first tank 1. The rotating shaft 32 is positioned vertically at the center of the inner cavity of the first tank 1. The top end of the rotating shaft 32 is connected to the output shaft of the drive motor 31 (e.g., via a flange, bolts, and a sealing ring). The stirring blades 33 are connected to the outer wall of the rotating shaft 32. Several stirring blades 33 are provided, and their ends are fixedly connected to the outer wall of a collar (e.g., via an integral fixed connection or by welding). The several stirring blades 33 are arranged in a circumferential array on the outer wall of the collar. The collar is fitted onto the outer wall of the rotating shaft 32 and fixedly connected (e.g., via bolts). The output shaft of the drive motor 31 can drive the rotating shaft 32 and the stirring blades 33 to rotate, thereby causing the soft capsule original drug solution to flow and achieving homogenization of the soft capsule original drug solution.

[0050] Reference Figure 4The homogenizer 34 is inserted at an angle into the bottom of the first tank 1; a high-pressure liquid pump is installed inside the homogenizer 34. The homogenizer 34 can extract the original soft capsule liquid and re-push it into the first tank 1, forming a high-pressure liquid column 340. The high-pressure liquid column 340 can increase the disorder of the flow of the original soft capsule liquid in the first tank 1, thereby improving the mixing efficiency and effect. The homogenizer 34 is connected to an external power supply via wires.

[0051] Reference Figure 1 and Figure 5 The vacuum assembly 4 includes a spiral tube 41, a bent tube 42, a collection box 43, a vacuum pump 44, a first connecting pipe 45, a second connecting pipe 46, and a second valve body 47. The spiral tube 41 is vertical, with its bottom end connected to the top of the inner cavity of the first canister 1. The bent tube 42 is η-shaped with open ends, and its bottom end is connected to and communicates with the spiral tube 41. The upper part of the bent tube 42 is inserted into the bottom of the inner cavity of the collection box 43. One end of the first connecting pipe 45 is connected to the top of the inner cavity of the collection box 43, and the other end is connected to the vacuum pump 44. One end of the second connecting pipe 46 is connected to the top of the inner cavity of the collection box 43, and the other end is connected to the second valve body 47. The gas in the first canister 1 flows sequentially through the spiral tube 41, the bent tube 42, the collection box 43, the first connecting pipe, and the vacuum pump 44 before being discharged, thereby reducing the gas pressure in the first canister 1 for the bursting and discharge of microbubbles and air bubbles in the soft capsule original liquid. The working pressure range of the inner cavity of the first tank 1 is -0.09MPa to +0.09MPa.

[0052] Reference Figure 1 and Figure 5 If the splashing path of the liquid medicine droplets is straight or arc-shaped, they cannot pass through the inner cavity of the spiral tube 41. Therefore, this invention can prevent splashed liquid medicine droplets from entering the vacuum pump 44, thereby avoiding the problem of damage to the internal structure of the vacuum pump 44.

[0053] Reference Figure 1 , Figure 5 and Figure 6 The bent tube 42 is η-shaped, with the upper part of the bent tube 42 being n-shaped, which allows the top opening of the bent tube 42 to be as close as possible to the bottom of the collection box 43. A desiccant 431 is placed at the bottom of the inner cavity of the collection box 43, and a filter cotton layer 432 is laid on top of the desiccant 431. The end of the bent tube 42 is pressed against the upper surface of the filter cotton layer 432. The gas flowing out of the bent tube 42 will pass through the filter cotton layer 432 and the desiccant 431. The viscous substances and solid particles in the gas are intercepted by the filter cotton layer 432, while the water molecules in the gas are absorbed by the desiccant 431, thus preventing damage to the internal structure of the vacuum pump 44.

[0054] Reference Figure 1 , Figure 5 and Figure 6The collection box 43 has a side cover that can be opened and closed. The side cover can be fastened into a side door opening in the side wall of the collection box 43. The bottom of the side cover is rotatably connected to the side wall of the collection box 43 (e.g., via a hinge), and the top is detachably connected to the side wall of the collection box 43 (e.g., via a spring-loaded buckle). The user can open the side cover to reach into the interior of the collection box 43, remove the old filter cotton layer 432, and replace it with a new one. The collection box 43 has a sloping bottom surface, and a discharge pipe 435 (e.g., fixed by welding) is installed at the bottom end of the sloping bottom surface. A second ball valve 436 is installed in the middle of the discharge pipe 435. The user opens the side cover and the second ball valve 436, inserts a brush into the interior of the collection box 43, and brushes the desiccant 431 until it leaks out of the discharge pipe 435; then the user closes the second ball valve 436 and adds new desiccant 431 into the collection box 43.

[0055] A sealing ring is fitted on the outer edge of the side cover plate. When the side cover plate is closed, the sealing ring acts as a seal between the side cover plate and the side wall of the collection box 43 to prevent the desiccant 431 from getting damp when it is not in operation.

[0056] Reference Figure 6 and Figure 7 The filter cotton layer 432 has a notch 4321 at the edge. When the filter cotton layer 432 is installed in the collection box 43, the middle part of the bent tube 42 is inserted into the notch 4321, so as to achieve the flatness of the filter cotton layer 432 and avoid wrinkles.

[0057] Reference Figure 5 and Figure 8 The bottom of the housing of the drive motor 31 is fixedly connected to the top surface of the first tank 1 (e.g., by bolts). The vacuum assembly 4 also includes a number of support rods 48 in the shape of a number 7, arranged in a circular array around the drive motor 31. The top end of the support rod 48 is fixedly connected to the housing of the drive motor 31 (e.g., by bolts or by welding), and the bottom end is fixedly connected to the first tank 1 (e.g., by bolts or by welding), thereby strengthening the fixation of the drive motor 31.

[0058] Reference Figure 5 and Figure 8 A first gap 481 is provided between two adjacent support rods 48, and the collection box 43 is placed within the first gap 481; the collection box 43 is fixedly connected to the support rods 48. The two side walls of the collection box 43 are respectively fixedly connected to the support rods 48 located on both sides of the first gap 481 (for example, by bolts). The support rods 48 are used to support the collection box 43, so that the bottom of the collection box 43 is suspended, avoiding the problem of the collection box 43 pressing the spiral tube 41 and causing it to deform (when the spiral tube 41 is pressed and deformed, it will cause the inner cavity to be blocked, and then the air in the inner cavity of the first tank 1 cannot be extracted).

[0059] Reference Figure 5 and Figure 8 The vacuum pump 44 is horizontally positioned above the first gap 481. Both ends of the vacuum pump 44 are respectively pressed and fixed to the support rods 48 located on both sides of the first gap 481, achieving a suspended installation of the bottom of the vacuum pump 44, thus facilitating heat dissipation from the bottom of the vacuum pump 44. The upper part of the side wall of the collection box 43 is fixedly connected to the side wall of the vacuum pump 44 (e.g., by bolts), thereby achieving stable installation of the vacuum pump 44.

[0060] Reference Figure 9 and Figure 10 The mixing assembly 3 also includes a limiting bracket 35, with the rotating shaft 32 inserted into the middle of the limiting bracket 35 and capable of relative rotation. The limiting bracket 35 is used to limit the lower middle part of the rotating shaft 32, thereby improving the rotational stability of the rotating shaft 32.

[0061] Reference Figure 9 , Figure 10 and Figure 11 The limiting bracket 35 includes a support rod 351 and a limiting ring 352. The support rod 351 is provided in a plurality of positions arranged in a circumferential array around the limiting ring 352. One end of the support rod 351 is fixedly connected to the limiting ring 352 (e.g., by bolt or by welding), and the other end is fixedly connected to the inner wall of the first tank 1 (e.g., by bolt or by welding).

[0062] Reference Figure 9 and Figure 10 The stirring blades 33 are provided in two sets: a first set of blades 331 and a second set of blades 332. The first set of blades 331 is located above the second set of blades 332. The first set of blades 331 is located in the middle of the inner cavity of the first tank 1, and the second set of blades 332 is located in the lower part of the inner cavity of the first tank 1, thereby stirring the middle and lower parts of the original soft capsule solution respectively, improving stirring efficiency. (Refer to...) Figure 9 The limiting bracket 35 is located between the first blade group 331 and the second blade group 332. (Refer to...) Figure 10 The limiting bracket 35 is located between the second fan blade group 332 and the discharge pipe 12, and the original liquid of the soft capsule can pass through the gap between the adjacent support rods 351 and flow out smoothly through the discharge pipe 12.

[0063] Reference Figure 1The first tank 1 has a discharge pipe 12 at its bottom, which is vertically positioned. The top of the discharge pipe 12 is fixedly connected to the bottom of the first tank 1 (e.g., by welding). The bottom of the discharge pipe 12 has a first valve body 13. After the user opens the second valve body 47 and lets it stand for a period of time (until the internal and external air pressure of the first tank 1 is balanced), the first valve body 13 is then opened to discharge the processed soft capsule raw medicine solution. An air filter is installed at the end of the second valve body 47 away from the second connecting pipe 46 to prevent impurities in the outside air (such as dust particles) from entering the collection box 43 and the vacuum pump 44.

[0064] A temperature sensor is horizontally inserted and sealed inside the housing 21, with its probe inserted into the receiving gap 22. The temperature sensor is used to monitor the temperature of the heating fluid in the receiving gap 22 in real time; when the temperature reaches a preset value, the user cuts off the power to the electric heating element 27 to prevent overheating.

[0065] This invention has a simple structure and reliable function. Since the splashing path of the liquid medicine droplets is straight or arc-shaped, they cannot pass through the inner cavity of the spiral tube 41. Therefore, this invention can prevent splashed liquid medicine droplets from entering the vacuum pump 44, thereby avoiding the problem of damage to the internal structure of the vacuum pump 44.
