Description
Technical Field
[0001] This utility model relates to the field of mixing tank technology, and in particular to a high-efficiency injection solution mixing tank mixing impeller. Background Technology
[0002] The stirring paddle of the high-efficiency injection preparation tank is the core component installed inside the injection preparation tank. The material must meet the requirements, and it has a structure such as a paddle type that is suitable for the characteristics of the drug solution and the rotation speed can be controlled. It mainly generates shear force and circulation flow through rotation to achieve uniform mixing of the drug solution to ensure consistent composition, accelerate the dissolution and dispersion of poorly soluble drugs to improve efficiency, maintain the homogeneity of the drug solution and assist in temperature control to ensure stability. The high-efficiency injection preparation tank stirring paddle mainly consists of a stirring shaft, which is mostly made of stainless steel and serves as a support and transmission mechanism and connects the drive motor and the paddle blades; paddle blades designed with different structures according to the characteristics of the drug solution and which complete the mixing and dissolution of the drug solution by rotation; and connection and sealing components, including shaft and paddle blade connection parts to ensure firmness and shaft through tank wall sealing components to prevent leakage of impurities. All components meet the requirements of pharmaceutical production. In existing technologies, before starting the mixing process in a high-efficiency injection preparation tank, solid drug powder or excipients need to be manually added from the tank's inlet. Because there is no dedicated feeding mechanism, operators must move the materials to the tank opening and then pour them out. Manual handling is limited by height and force, causing some materials to adhere to the edge of the inlet or the top of the tank wall, preventing them from falling directly into the mixing area. The speed and angle of manual pouring are difficult to control precisely, leading to localized material accumulation inside the tank. The mixing paddle must first break up the accumulated material to achieve uniform mixing, extending the mixing time. Furthermore, manual feeding results in a large contact area between the material and air, easily generating dust, causing material loss and increasing the risk of external impurities entering the tank. Additional time is required to clean the inlet and replenish the material, further affecting mixing efficiency and drug purity control. Therefore, a high-efficiency injection preparation tank mixing paddle is proposed to solve these problems. Utility Model Content
[0003] To overcome the above shortcomings, this utility model provides a high-efficiency injection preparation tank stirring paddle, which aims to improve the problems of existing stirring paddles requiring manual feeding, resulting in material adhesion and accumulation leading to long preparation time, as well as material loss and impurities entering the tank affecting preparation efficiency and drug purity.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency injection solution mixing tank stirring paddle, including a tank body, a motor fixedly connected to the top of the tank body, a stirring blade fixedly connected to the drive end of the motor, a feeding mechanism fixedly connected to the outside of the tank body, and an overload protection mechanism fixedly connected to the inside of the tank body. The feeding mechanism includes a base, the outer side of which is fixed to the outer side of the tank body, a support seat is fixedly connected to the top of the base, a storage box is fixedly connected to the inside of the support seat, a fixed frame is fixedly connected to one side of the support seat, a fixed seat is rotatably connected to the other end of the fixed frame, a fixed ring is fixedly connected to the bottom of the fixed seat, and a drive assembly is fixedly connected to the bottom of the fixed ring. As a further description of the above technical solution: The overload protection mechanism includes a water inlet pipe, the outer side of which is fixed inside the tank body. A shell is fixedly connected to the bottom of the water inlet pipe. A float plate is slidably connected inside the shell. A connecting column is fixedly connected to the top of the float plate. A water-stop block is fixedly connected to the top of the connecting column. As a further description of the above technical solution: The drive assembly includes a positioning seat, the outer side of which is fixedly connected to the outer side of the fixing ring, and a pneumatic cylinder is rotatably connected to the outer side of the positioning seat. A connecting rod is fixedly connected to the drive end of the pneumatic cylinder. As a further description of the above technical solution: The outer side of the outer shell is fixedly connected to the inside of the tank, and the outer side of the water inlet pipe is fixedly connected to the top of the fixing ring; As a further description of the above technical solution: The outer side of the connecting column is slidably connected to the inside of the outer shell, and the outer side of the water-stop block is slidably connected to the inside of the water inlet pipe; As a further description of the above technical solution: The two ends of the connecting rod are fixedly connected to the inner side of the fixed frame, and the outer side of the fixed frame is fixedly connected to the outer side of the storage box. As a further description of the above technical solution: The outer side of the base is rotatably connected to the outer side of the fixing ring, and the outer side of the fixing frame is rotatably connected to the top of the fixing seat; As a further description of the above technical solution: The bottom of the storage bin is fixedly connected to the top of the base, and the bottom of the pneumatic cylinder is fixedly connected to the outside of the base.
[0005] This utility model has the following beneficial effects: In this invention, a motor drives the stirring blades inside the tank, while a feeding mechanism is installed on the outside of the tank to achieve quantitative feeding. The drive structure drives the linkage structure, and a support base at the top of the base secures the storage box. A fixing frame is mounted on the outside of the support base, and a fixing ring is fixed to the outside of the tank to provide support. The bottom of the fixing base is fixed to the top of the fixing ring, allowing the storage box to rotate around it. The drive assembly is mounted on the bottom of the fixing ring via a positioning seat, supporting a pneumatic cylinder. The pneumatic cylinder pushes a connecting rod connected to the fixing frame, causing the storage box to rotate and tilt on the outside of the tank, completing the feeding process. Compared to existing technologies, this invention reduces manual intervention and improves feeding efficiency and the purity of the medicine.
[0006] In this invention, an overload protection mechanism is installed inside the tank to prevent water overflow due to overload. The protective structure drives a sliding mechanism, injecting liquid into the tank through the inlet pipe. When the water volume approaches overload, the injection liquid enters the outer shell through a hole at the bottom, lifting an internal float plate. The float plate moves horizontally along a groove inside the inlet pipe, causing the connecting column to push the water-stop block upwards. This effectively blocks the inlet pipe, preventing water from continuing to flow into the tank. Compared to existing technologies, this invention automatically prevents water overflow due to overload and improves the safety of liquid preparation. Attached Figure Description

A motor 2 is fixedly connected to the top of the tank 1, providing stable power for stirring. The motor 2 can precisely adjust the speed to adapt to the stirring needs of different liquid solutions, improving the uniformity of stirring. A stirring blade 5 is fixedly connected to the drive end of the motor 2. The stirring blade 5 rotates with the motor 2 to achieve thorough mixing of the liquid solution, reducing the problem of uneven distribution of liquid components and ensuring the consistency of the prepared solution concentration. A feeding mechanism 3 is fixedly connected to the outside of the tank 1, which can achieve precise quantitative delivery of materials, avoiding errors and contamination from manual feeding, and improving feeding efficiency and safety. An overload protection mechanism 4 is fixedly connected inside the tank 1. The overload protection mechanism 4 can monitor the load of the motor 2 and the stirring blade 5, and cut off the power in time when overload occurs to prevent damage to components and interruption of liquid preparation. Specifically, tank 1 provides a sealed liquid preparation space. After the top motor 2 starts, it outputs power to drive the stirring blades 5 below to rotate, so that the liquid in the tank is fully mixed. The speed of motor 2 can be precisely controlled to adapt to the stirring requirements of different liquids. The feeding mechanism 3 on the outside of tank 1 delivers the material quantitatively into the tank, avoiding human contamination and errors. The overload protection mechanism 4 inside the tank monitors the load of motor 2 and stirring blades 5 in real time. Once overloaded, it immediately cuts off the power to protect the components and ensure the stability and safety of the liquid preparation process, ultimately ensuring the cleanliness and concentration consistency of the injection solution.
[0011] The feeding mechanism 3 includes a base 31, which provides stable support for the feeding mechanism 3, ensuring that the mechanism does not shake during the feeding process and improving feeding stability. The outer side of the base 31 is fixed to the outer side of the tank body 1, making the feeding mechanism 3 and the tank body 1 a stable whole, avoiding relative displacement during feeding that would affect feeding accuracy. A support seat 32 is fixedly connected to the top of the base 31, which provides stable support for components such as the storage box 33, ensuring that all components of the feeding mechanism 3 are firmly installed. The storage box 33 is fixedly connected inside the support seat 32, which can temporarily store materials to be fed, enabling continuous material supply and avoiding frequent feeding that would affect the liquid preparation efficiency. A fixing frame 34 is fixedly connected to one side of the support base 32. The fixing frame 34 provides installation support for the fixing base 35, ensuring the stability of the position of components such as the drive assembly 37. The other end of the fixing frame 34 is rotatably connected to the fixing base 35. The fixing base 35 can be flexibly adjusted to adapt the fixing ring 36 and the drive assembly 37 to different feeding angle requirements. The bottom of the fixing base 35 is fixedly connected to the fixing ring 36. The fixing ring 36 realizes the stable installation of the drive assembly 37 and prevents the drive assembly 37 from loosening during operation. The bottom of the fixing ring 36 is fixedly connected to the drive assembly 37, which provides power for feeding and realizes the uniform and accurate delivery of materials into the tank 1. Specifically, the base 31 is fixed to the outside of the tank 1, providing stable support for the entire feeding mechanism 3. Its top support 32 supports the storage bin 33 to temporarily store materials. The fixing bracket 34 on one side of the support 32 is connected to the fixing seat 35. The fixing seat 35 is adjustable in angle, which drives the bottom fixing ring 36 and the drive component 37 to adapt to the required feeding angle. The fixing ring 36 stabilizes the drive component 37. After the drive component 37 is started, it provides power to uniformly and accurately transport the materials in the storage bin 33 to the tank 1, achieving stable feeding.
[0012] Reference Figure 1 , Figure 2 and Figure 4 The overload protection mechanism 4 includes a water inlet pipe 41, which can supply liquid into the outer shell 42 to provide a medium basis for triggering the protection mechanism.

The bottom of the water inlet pipe 41 is fixedly connected to the outer shell 42, which provides a closed space for components such as the float plate 43 to ensure that they run according to a preset trajectory. The float plate 43 is slidably connected inside the outer shell 42. The float plate 43 can slide up and down with the liquid volume change and serves as the core moving component for triggering protection. The top of the float plate 43 is fixedly connected to a connecting column 44, which can transmit the displacement of the float plate 43 and drive the water stop block 45 to move synchronously. The top of the connecting column 44 is fixedly connected to a water stop block 45, which can block the water flow when it is displaced to the port of the water inlet pipe 41, realizing liquid supply cut-off protection during overload. Specifically, the inlet pipe 41 is fixed inside the tank 1 and supplies liquid to the outer shell 42. The outer shell 42 provides a closed space for the internal float plate 43. The float plate 43 slides upward as the amount of liquid inside the shell increases. The top connecting column 44 drives the water stop block 45 to move upward synchronously. When the overload threshold is reached, the water stop block 45 is just moved to the port of the inlet pipe 41 to block the water supply, thereby triggering the protection mechanism and preventing subsequent components from being damaged due to overload.

Specifically, the positioning seat 371 is fixed on the outside of the fixing ring 36 to provide an installation reference for the pneumatic cylinder 372. The pneumatic cylinder 372 can rotate to adjust the driving angle. Its driving end transmits power through the connecting rod 373. The water inlet pipe 41 is fixed on the top of the fixing ring 36 to ensure stable liquid delivery. The outer shell 42 is fixed inside the tank 1. The connecting column 44 is slidably connected inside the shell, so that the connecting column 44 slides directionally inside the shell. With the power output of the pneumatic cylinder 372, the precise linkage between driving and delivery is achieved.
[0014] The outer side of the water-stop block 45 is slidably connected to the inside of the water inlet pipe 41, allowing the water-stop block 45 to precisely seal the water inlet pipe 41 and ensure the airtightness of the water flow. The two ends of the connecting rod 373 are fixedly connected to the inner side of the fixing frame 34, so that the connecting rod 373 and the fixing frame 34 form a stable linkage structure, improving the stability of power transmission. The outer side of the fixing frame 34 is fixedly connected to the outer side of the storage box 33, enhancing the support strength of the fixing frame 34 and preventing the accuracy from being affected by shaking due to force during material feeding. The outer side of the base 31 is rotatably connected to the fixing ring 3. The outer side of the fixed ring 36 allows the angle of the fixed ring 36 to be flexibly adjusted to adapt to different feeding positions. The outer side of the fixed frame 34 is rotatably connected to the top of the fixed base 35, allowing the fixed frame 34 to be finely adjusted to ensure accurate alignment of the feeding components. The bottom of the storage box 33 is fixedly connected to the top of the base 31, so that the storage box 33 is placed stably and to prevent leakage caused by shaking when storing materials. The bottom of the pneumatic cylinder 372 is fixedly connected to the outer side of the base 31, providing bottom support for the pneumatic cylinder 372 and improving its load-bearing capacity during operation. Specifically, the water-stop block 45 slides within the inlet pipe 41, precisely sealing and blocking the water flow. One side of the fixed frame 34 is connected to the storage bin 33 for enhanced support, while the other side is rotatably connected to the fixed base 35, allowing for fine-tuning of the angle. The inner side is fixed with a connecting rod 373 for stable force transmission. The storage bin 33 is fixed to the top of the base 31 to prevent swaying.

[0015] The implementation principle of this application embodiment is as follows: The mixing tank is driven by the motor 2 to work inside the tank body 1. The feeding mechanism 3 is installed on the outside of the tank body 1 for quantitative feeding. The feeding mechanism 3 is fixed by the support seat 32 installed on the top of the base 31 to fix the storage box 33. The fixing frame 34 is installed on the outside of the support seat 32. The fixing ring 36 is fixed on the outside of the tank body 1 to support the whole. The bottom of the fixing seat 35 is fixed to the top of the fixing ring 36, so that the storage box 33 rotates around the fixing seat 35. The driving component 37 drives the storage box 33 to rotate to the outside of the tank body 1, so that the storage box 33 tilts to feed the tank body 1. The driving component 37 is installed on the bottom of the fixing ring 36 through the positioning seat 371 to support the bottom of the pneumatic cylinder 372. The driving pneumatic cylinder 372 pushes the connecting rod 373 on the outside of the fixing frame 34. The fixing frame 34 is connected to the connecting rod 373, so that the storage box 33 is lifted upward.
[0016] An overload protection mechanism 4 is installed inside the tank 1 to prevent water from overflowing due to overload. The overload protection mechanism 4 injects injection fluid through the water inlet pipe 41. When the water volume is about to overload, the injection fluid enters the interior of the outer shell 42 through the hole at the bottom of the outer shell 42. The float plate 43 placed inside the outer shell 42 is then lifted by the water flow. The float plate 43 is horizontally lifted along the sliding groove inside the water inlet pipe 41. The connecting column 44 connecting the float plate 43 pushes the water stop block 45 upward, so that the water stop block 45 blocks the water inlet pipe 41 and prevents water from re-entering the tank 1.
