Description

Technical Field

[0001] This utility model relates to the field of vaccine production technology, specifically a high-precision vaccine production ingredient mixing tank. Background Technology

[0002] In the biopharmaceutical field, vaccine production processes place extremely high demands on ingredient precision and mixing uniformity. As a core piece of equipment, the ingredient mixing tank's structural design directly impacts vaccine quality stability. Existing vaccine production ingredient mixing tanks typically employ traditional stirring structures, using a single stirring motor to drive a stirring rod for material mixing, which presents the following technical bottlenecks:

[0003] On the one hand, the material feeding system of traditional batching tanks is mostly an open structure, with raw materials falling directly into the tank through the feed hopper. It lacks a precise material guiding device, which can easily lead to confusion in the feeding paths of different materials, affecting the accuracy of the batching ratio. At the same time, the materials collide with the side wall of the tank during the falling process, causing splashing, resulting in raw material waste and pollution risks.

[0004] On the other hand, the existing stirring mechanism has a relatively simple stirring rod layout, which is not good for shearing and mixing high-viscosity materials, and there are dead corners in the stirring area, making it difficult to meet the strict requirements of material uniformity in vaccine production. In the quantitative feeding process, some equipment relies on manual control of the feeding valve, which is not only inefficient, but also greatly affected by human factors, and cannot achieve automated and precise feeding.

[0005] Furthermore, traditional mixing tanks have shortcomings in sealing structure and ease of cleaning, making it difficult to completely remove residual materials inside, increasing the risk of cross-contamination, and failing to meet the stringent GMP requirements for pharmaceutical equipment. With the upgrading of vaccine production processes, there is an urgent need for a new type of mixing tank that can achieve precise material feeding, efficient mixing, and automated control to solve the technical problems of existing equipment in terms of mixing accuracy, mixing effect, and ease of operation. Utility Model Content

[0006] The purpose of this invention is to provide a high-precision vaccine production ingredient container to solve the problems mentioned in the background art, such as insufficient material feeding accuracy, poor mixing effect, low degree of automation in quantitative ingredient dispensing, and poor cleaning convenience.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-precision vaccine production ingredient tank, comprising a tank body, a support foot fixedly provided on the lower outer surface of the tank body, and a tank cover fixedly installed on the upper end of the tank body by bolts, a feed hopper fixedly provided on the upper end of the tank cover, and a stirring motor fixedly installed on the upper surface of the tank cover, the lower end of the output shaft of the stirring motor penetrating the inner top surface of the tank cover, and a functional disk fixedly connected to the lower end of the output shaft of the stirring motor, the functional disk being double-layered, a guide pipe fixedly installed on the outer surface of the functional disk, an installation disk fixedly connected to the lower end of the functional disk, and a stirring rod fixedly provided on the lower surface of the installation disk;

[0008] A push switch is fixedly installed inside the lower end of the function panel. An electric push rod is fixedly installed on the inner bottom surface of the tank. A lifting rod is fixedly connected to the upper end of the electric push rod, and a hopper is fixedly connected to the lower end of the lifting rod. A discharge port is opened on the lower surface of the hopper, and a sealing plate is provided on the inner side of the discharge port.

[0009] Preferably, the upper surface of the functional disk is in contact with the inner top surface of the can lid, the upper end of the guide tube penetrates the upper surface of the functional disk, and the upper end of the guide tube is directly opposite the lower end of the feed hopper, while the lower end of the guide tube is directly opposite the holding hopper.

[0010] By adopting the above technical solution, it is possible to ensure that the material is accurately and directionally conveyed from the feed hopper to the holding hopper through the guide pipe, avoiding the chaotic material feeding path and splashing caused by collision with the side wall of the tank, thus ensuring the accuracy of the batching ratio from the source. At the same time, the direct alignment design of the guide pipe and the holding hopper provides conditions for the subsequent material to fall and mix with the fluid in the tank.

[0011] Preferably, the mounting plate has a hollow design, and the mounting plate is engaged with the hopper, with the outer surface of the mounting plate fitting against the inner surface of the tank.

[0012] Using the above technical solution, the hollowed-out installation plate can reduce material residue on the plate surface. At the same time, the structure that fits into the inner surface of the tank can guide the material to flow along the tank wall. Combined with the snap-fit ​​hopper, the mixing range is expanded during the mixing process, effectively eliminating the mixing dead corners near the bottom and side walls of the tank, and improving the uniformity of material mixing.

[0013] Preferably, the stirring rods are distributed at equal angles on the lower surface of the mounting plate, and columnar protrusions are uniformly provided on the outer surface of the stirring rods.

[0014] By adopting the above technical solution, the equidistantly distributed stirring rods can form a full-area covering and stirring of the material when rotating. The uniformly arranged columnar protrusions on the outer side can enhance the shearing force on high-viscosity materials, break up particle agglomeration, and significantly improve the mixing efficiency of the stirring mechanism for materials of different viscosities, thus meeting the stringent requirements of vaccine production for material uniformity.

[0015] Preferably, the push switch is located directly above the lifting rod, and the upper end of the lifting rod is in contact with the lower end of the push switch.

[0016] By adopting the above technical solution and designing the positions of the lifting rod and the push switch to correspond, when the electric push rod drives the lifting rod to rise, the upper end of the lifting rod is in contact with the push switch, triggering the linkage control of the stirring motor starting and the lifting rod descending, thereby realizing the automatic connection between material feeding and stirring, avoiding the inefficiency and batching errors caused by manual intervention.

[0017] Preferably, the outer surface of the sealing plate is in contact with the inner surface of the discharge port, and the sealing plate and the hopper are slidably connected.

[0018] By adopting the above technical solution, the fitting design between the sealing plate and the inner surface of the discharge port can ensure the sealing of the hopper when receiving materials, preventing materials from falling prematurely. The sliding connection structure facilitates precise control of the opening and closing of the discharge port under the drive of the electric push rod, realizing quantitative feeding of materials, while reducing the risk of material residue caused by mechanical gaps and ensuring the accuracy of batching.

[0019] Compared with the prior art, the beneficial effects of this utility model are: This high-precision vaccine production mixing tank:

[0020] 1. By setting a guide pipe on the can lid that precisely connects with the feed hopper, the material is directionally conveyed to the holding hopper through a double-layer functional disc, avoiding the path confusion and side wall splashing problems caused by traditional open feeding. This ensures the accuracy of the ingredient ratio from the source. The design of the lower end of the guide pipe facing the holding hopper, together with the lifting rod driven by the electric push rod and the closing plate, can achieve the purpose of mixing the material by the impact of the fluid below during the falling process, so that various materials can be fully mixed.

[0021] 2. The hollowed-out mounting plate fits snugly against the inner wall of the tank, and the stirring rods, with their evenly distributed angles and columnar protrusions, expand the stirring range and enhance the shearing force for high-viscosity materials, effectively eliminating dead zones in the stirring process. Simultaneously, the linkage control between the electric push rod and the push switch allows the lower end of the feed hopper to automatically open and close according to a preset program, avoiding inefficiency and contamination risks caused by manual intervention. The way the upper surface of the function plate fits snugly against the inner top of the tank lid reduces the space for residual materials. Furthermore, the modular structure of the tank body and lid facilitates disassembly and cleaning, meeting the aseptic requirements for pharmaceutical equipment and significantly reducing the risk of cross-contamination.

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a high-precision vaccine production ingredient mixing tank.

[0031] Example 1: This example discloses: a tank body 1, with a support leg 2 fixedly installed on the lower outer surface of the tank body 1, and a tank cover 3 fixedly installed on the upper end of the tank body 1 by bolts, with a feed hopper 4 fixedly installed on the upper end of the tank cover 3, and a stirring motor 5 fixedly installed on the upper surface of the tank cover 3, the lower end of the output shaft of the stirring motor 5 penetrating the inner top surface of the tank cover 3, and a function disk 6 fixedly connected to the lower end of the output shaft of the stirring motor 5, and the function disk 6 is double-layered, with a guide pipe 7 fixedly installed on the outer surface of the function disk 6, and an installation disk 8 fixedly connected to the lower end of the function disk 6, and a stirring rod 9 fixedly installed on the lower surface of the installation disk 8;

[0032] The upper surface of the function plate 6 is in contact with the inner top surface of the can lid 3. The upper end of the guide pipe 7 penetrates the upper surface of the function plate 6, and the upper end of the guide pipe 7 is directly opposite the lower end of the feed hopper 4, and the lower end of the guide pipe 7 is directly opposite the holding hopper 13.

[0033] The stirring rods 9 are evenly distributed on the lower surface of the mounting plate 8, and columnar protrusions are evenly arranged on the outer surface of the stirring rods 9.

[0034] The tank 1 is stably placed on the ground by the support legs 2. After the material enters from the feed hopper 4, it is vertically conveyed to the area below the function plate 6 through the upper opening of the guide pipe 7. The lower end of the guide pipe 7 is precisely aligned with the hopper 13 to avoid the material from colliding with the side wall of the tank 1, thus solving the problems of chaotic path and splashing, and ensuring the accuracy of the batching ratio.

[0035] The functional panel 6 has a double-layer structure. Its upper surface fits against the inner top of the can lid 3, reducing the space for material residue. At the same time, it provides stable support for the guide tube 7, ensuring the sealing and orientation of the guide path.

[0036] The stirring motor 5 drives the functional disk 6 and the mounting disk 8 to rotate synchronously, which in turn drives the stirring rods 9, which are distributed at equal angles, to rotate at high speed. The columnar protrusions on the outer side of the stirring rods 9 increase the shearing force on the material, which is especially suitable for high-viscosity materials and can effectively break up particle agglomeration. The mounting disk 8 adopts a hollow design and its outer side is in close contact with the inner wall of the tank 1, which expands the stirring range, eliminates the stirring dead corners near the bottom and side walls of the tank, and realizes uniform mixing of materials in the entire area of ​​the tank 1, which meets the strict requirements of vaccine production for material uniformity.

[0037] Example 2: This example is based on Example 1: A push switch 10 is fixedly installed inside the lower end of the function panel 6, an electric push rod 11 is fixedly installed on the inner bottom surface of the tank body 1, and a lifting rod 12 is fixedly connected to the upper end of the electric push rod 11, and a hopper 13 is fixedly connected to the lower end of the lifting rod 12. A discharge port 14 is opened on the lower surface of the hopper 13, and a sealing plate 15 is provided on the inner side of the discharge port 14.

[0038] The push switch 10 is located directly above the lifting rod 12, and the upper end of the lifting rod 12 is in contact with the lower end of the push switch 10;

[0039] The outer surface of the sealing plate 15 is in contact with the inner surface of the discharge port 14, and the sealing plate 15 is slidably connected to the hopper 13.

[0040] In the initial state, the hopper 13 is located in the middle of the tank 1. The sealing plate 15 seals the discharge port 14 through a sliding connection. The material falls into the hopper 13 through the guide pipe 7. At this time, the electric push rod 11 drives the lifting rod 12 to move upward. The upper end of the lifting rod 12 is attached to and presses the lower end of the pressing switch 10 of the pressing function disk 6, triggering the control signal. On the one hand, the stirring motor 5 starts, driving the stirring rod 9 to start mixing.

[0041] On the other hand, the electric push rod 11 drives the lifting rod 12 to slide down, causing the fluid impact sealing plate 15 to slide open the discharge port 14. The material is impacted by the fluid and falls into the tank 1 to be fully mixed with the fluid, avoiding errors and pollution risks caused by manual intervention, and achieving precise quantitative feeding.

[0042] The tank body 1 and the tank cover 3 are detachably connected by bolts. The upper surface of the function plate 6 fits into the inner top of the tank cover 3. The design without dead corners reduces material residue. The hopper 13 is installed by engaging with the mounting plate 8, and the outer side of the mounting plate 8 fits into the inner wall of the tank body 1. During the stirring process, the material flows along the tank wall to avoid accumulation. When cleaning, the tank cover 3 can be completely removed to thoroughly clean each component, which meets the aseptic requirements of the standard for pharmaceutical equipment and significantly reduces the risk of cross-contamination.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
