Description

Technical Field

[0001] This utility model relates to the technical field of gel preparation instruments, specifically a gynecological gel raw material reaction vessel. Background Technology

[0002] In the preparation of gynecological gel raw materials, the mixing effect of the reaction vessel directly affects the uniformity, stability, and final quality of the product. Traditional mixing equipment often uses single-axial stirring at a fixed speed or simple anchor stirring. These methods often have significant shortcomings when dealing with high-viscosity gel raw materials with non-Newtonian fluid characteristics: First, the stirring flow field is singular and has dead zones, making it difficult to achieve efficient and uniform mixing of materials within the vessel, especially between the vessel walls and the central area, easily leading to uneven material dispersion and incomplete reaction. Second, the angle and position of the stirring blades are fixed, making dynamic adjustment impossible according to changes in material viscosity or the process requirements of different reaction stages, resulting in poor adaptability and insufficient process flexibility. Third, the mixing process usually lacks intelligent coordination with temperature control, while the gelation reaction is temperature-sensitive, and traditional equipment struggles to achieve precise linkage between mixing and temperature control. Fourth, from a hygiene and safety perspective, ordinary reaction vessels may not fully utilize corrosion-resistant, biocompatible materials and reliable dynamic sealing structures that comply with biopharmaceutical manufacturing standards, posing a risk of contamination or equipment damage. Therefore, this case study was developed to address these issues. Utility Model Content

[0003] To address the aforementioned problems, specifically those raised in the background section, this invention provides a gynecological gel raw material reaction vessel, comprising an equipment rack, a vessel body, a drive motor, end caps, and a main shaft. The vessel body is mounted on the equipment rack, and the main shaft is rotatably mounted within the vessel body. The end caps are mounted above the vessel body, and the drive motor is mounted above the end caps. The top end of the main shaft passes through the end caps and is connected to the drive motor via a coupling. One side of the vessel body is provided with an inlet flange for connecting a feeding device and an outlet flange for discharging material. A colloid pump is mounted above the equipment rack, and the outlet flange is connected to the colloid pump. A sealing plate and a pulsator are fixedly fitted onto the upper and lower sides of the outer wall of the main shaft, respectively. The sealing plate seals the top of the interior of the vessel body, and an arc-shaped pulsator blade is positioned above the pulsator. Multiple stirring rollers are arranged in a ring between the sealing plate and the pulsator.

[0004] A further feature of this invention is that an outer tank is installed on the outside of the main tank, and a gap is left between the inner wall of the outer tank and the outer wall of the main tank. The end cap seals the top of the outer tank. An inlet valve and an outlet valve are installed on the outer tank. A water pump for supplying water bath liquid is installed above the equipment placement rack. The inlet valve is connected to the water pump.

[0005] A further feature of this invention is that: the two ends of the stirring rod are rotatably mounted on the sealing plate and the impeller, respectively; stirring blades are installed on the outer wall of the stirring rod; an annular cavity is opened below the end cap; the sealing plate is configured to seal the annular cavity in a frustum shape; internal teeth are machined on the inner wall of the annular cavity; the top end of the stirring rod penetrates the sealing plate; and a planetary gear is fixedly sleeved on the top end of the stirring rod, with the planetary gear meshing with the internal teeth.

[0006] A further feature of this invention is that the stirring rods are distributed in a vortex shape above the impeller with the main shaft as the center.

[0007] A further feature of this invention is that the stirring blade is configured as a C-shaped roller, and the C-shaped roller is distributed in a ring around the outer wall of the stirring roller.

[0008] The beneficial technical effects of this utility model are as follows: First, the impeller blades promote the flow of the colloid, and the stirring of the stirring rods, combined with the planetary gears, drives the stirring blades to rotate, realizing a multi-dimensional synergistic stirring system (revolution, radial movement, and rotation), achieving composite motion in three-dimensional space, effectively eliminating mixing dead zones, and significantly improving the mixing uniformity and reaction efficiency of high-viscosity, non-Newtonian fluid gel raw materials; by distributing the stirring rods in a vortex shape, the coverage of the running trajectory of the stirring rods and stirring blades is increased, and an array distribution that promotes the flow of the colloid is formed. Combined with the thrust of the impeller blades, uniform stirring of the colloid is achieved to ensure sufficient reaction; secondly, the external tank provides a water bath to provide a suitable ambient temperature for the reaction, realizing intelligent synergy between the mixing process and precise temperature control, meeting the sensitive temperature requirements of the gelation reaction.

[0015] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0016] This invention proposes a reaction vessel for gynecological gel raw materials. Traditional reaction vessels use fixed stirring blades on the main shaft to promote mixing and reaction. However, the high viscosity and poor flowability of the colloid result in dead zones where the colloid has extremely low flowability and cannot be mixed. This solution uses a pulsator 14 and pulsator blades 15 instead of fixed stirring blades to promote the flow of the colloid. A ring-shaped stirring rod is added to increase the area covered by the stirring trajectory and eliminate dead zones. The raw materials are supplied to the tank 2 through a feeding device and an inlet flange. The pulsator 14 is driven to rotate by a drive motor 4 via the main shaft 5. A sealing plate 7 is set at the top inside the tank 2. The two ends of the stirring rod 8 are distributed on the pulsator 14 and the sealing plate 7, thereby driving the stirring rod 8 to rotate. This avoids uneven force distribution on the drive structure due to excessive colloid resistance, which affects the service life. After the reaction is completed, the colloid is discharged through a colloid pump 10 and an outlet flange. The pulsator blades 15 at the bottom rotate slowly to promote the flow of the colloid to the outlet flange for discharge.

[0017] An outer tank 3 is installed outside the tank body 2, and a gap is left between the outer tank 3 and the tank body 2. Water bath liquid is supplied through water pump 11 and inlet valve, so that the reaction can be carried out in a suitable temperature environment. The outlet valve is connected to the water bath liquid supply equipment through a pipeline to realize the circulation of water.

[0018] An annular cavity is formed below the end cap 6. The sealing plate 7 is set in a frustum shape to seal the annular cavity and is filled by dynamic sealing. The internal gears 13 and planetary gears 12 are set in the annular cavity. The stirring rod 8 is rotatably mounted on the sealing plate 7 and the impeller 14. The top of the stirring rod 8 is connected to the planetary gear 12. When the main shaft 5 drives the stirring rod 8 through the sealing plate 7 and the impeller 14, the planetary gear 12 rotates on the internal gears 13 and drives the stirring rod 8 to drive the stirring blades 9 to rotate, thereby performing multi-dimensional stirring. The stirring blades 9 are set in a C-shaped structure with annular distribution to reduce resistance while ensuring the stirring and mixing effect. At the same time, the planetary gears and internal gears form an acceleration mechanism, and the stirring effect is increased by the speed difference between the main shaft 5 and the stirring rod 8.

[0019] The stirring rollers 8 are arranged in a vortex shape around the main shaft 5 on the impeller 14. The ratio of the number of teeth of the planetary gears to the number of teeth of the internal gears is adjusted accordingly. While increasing the coverage of the running trajectory of the stirring rollers 8, the shear force generated by the speed difference of multiple stirring blades 9 promotes the mixing reaction, ensuring the reaction is complete to the greatest extent. Furthermore, the vortex distribution combined with the rotation of the impeller blades 15 promotes the fluidity of the colloid.

In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict.
