Description

Technical Field

[0001] This utility model relates to the technical field of gynecological gel raw material dilution equipment, specifically a gynecological gel raw material dilution equipment. Background Technology

[0002] In the production of gynecological gels, raw material dilution is a crucial step, directly affecting the product's stability, uniformity, and efficacy. Currently, the dilution of high-viscosity gel raw materials mainly relies on the following methods: 1. Traditional mixing tank: Intermittent mixing using mechanical stirrers (such as paddle, anchor, or spiral stirrers). Disadvantages: Low mixing efficiency, long time consumption, difficulty in achieving continuous production, insufficient stirring shear force, easily leading to uneven gel distribution, affecting product quality, large batch-to-batch differences, and unfavorable for large-scale production. 2. Static mixer: Relies on the flow of fluid in a fixed spiral structure to achieve mixing, suitable for low-viscosity liquids. Disadvantages: High-viscosity gels have poor flowability and are prone to clogging the internal flow channels of the mixer. Limited mixing effect, difficulty in achieving nanoscale dispersion, affecting the uniformity of the gel. 3. Dynamic mixer (such as high-shear emulsifiers, colloid mills): Provides strong shear force through a high-speed rotating rotor-stator structure, suitable for high-viscosity materials. Disadvantages: Complex equipment structure, high maintenance costs. High energy consumption, long-term operation can easily lead to temperature rise, affecting the stability of heat-sensitive components. The mixing intensity is difficult to control precisely, which may lead to the destruction of the gel structure. Utility Model Content

[0003] To solve the above problems, namely the problems mentioned in the background art, this utility model proposes a gynecological gel raw material dilution device, including a pump body, a mixing chamber and a mixer connected to a raw material supply device. The mixing chamber is connected to the discharge chamber of the pump body through a connecting flange and a sealing element. The mixer is installed in the mixing chamber. One-way valves are provided at both the inlet and outlet chambers of the pump body. The mixer includes a front half of the first section, a rear half of the first section, an additional section and an end cap.

[0004] The mixer includes a first section, at least one additional section, and an end cap. The tail end of the first section is provided with a support post, the additional section is sleeved on the support post, and the end cap is threadedly connected to the tail end of the support post.

[0005] The first section includes an integrally formed front half and a rear half. The support column is located at the tail end of the rear half of the first section, and the additional section is attached to the tail end of the rear half of the first section. The front half of the first section has a mixing chamber inside. The mixing chamber is configured as a structure in which a tapered cavity with a gradually decreasing diameter communicates with a spherical cavity. The rear half of the first section is configured as an integrally formed spherical tail end connected to a circular baffle structure. The outer wall of the circular baffle is attached to the inner wall of the mixing chamber. A first jet port communicating with the mixing chamber is axially opened at the connection between the front half and the rear half of the first section. A second jet port is opened at the point where the circular baffle is attached to the spherical body.

The mechanical design of the mixer allows the gel raw materials to undergo cavitation and shearing effects step by step, so that the raw materials are gradually homogenized and the dilution process is completed, increasing the quality of the product. The mixer is set as a combination of multiple independent units, and the multiple independent unit sections can be combined and arranged as needed to realize customized production processes and reduce maintenance and replacement costs.

[0016] 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.

[0017] This invention proposes a gynecological gel raw material dilution device. The overall structure is similar to a static mixer. The raw material is transported to the feed chamber of the pump body 1 through a material supply device. In this design, the pump body uses a screw pump as the power supply device. The pump body 1 transports the material to the mixing chamber 2 for mixing and dilution. Since conventional static mixers are suitable for mixing fluids with low viscosity, they are not very effective for diluting gel raw materials with high viscosity. The pump design uses a screw pump to increase the high pressure, so that all raw materials pass through the mixer 3 at a higher pressure for mixing and dilution. Although conventional gel raw material mixing tanks can also perform gel raw material dilution, they can only be used for small-batch production and are not suitable for large-scale continuous production.

[0018] Since the gel raw material cannot be diluted using a static mixer through simple fluid spiral flow, this solution utilizes a screw pump to provide high pressure in conjunction with the fluid channel structure design of mixer 3, enabling a continuous dilution process for the gel raw material. Mixer 3 is composed of multiple independent units, and the combination of these units can be modified according to the physical properties of the raw material. Mixer 3 mainly consists of a first section, additional sections 306, and end caps 308. The first section comprises an integrally formed front half 301, a rear half 304, and a support column. Multiple additional sections 306 are sequentially fitted onto the support column at the tail end of the first section. The end caps 308 are installed at the tail end of the support column via external threads. 8. The first section, front half 301, is configured as a cylindrical structure capable of sealing the interior of the mixing chamber 2. The interior of the first section, front half 301, is configured as a structure connecting a tapered cavity with a spherical cavity, both with a gradually decreasing diameter. High-pressure gel mixture enters the spherical cavity through the tapered cavity. The high-speed passage of the gel material generates a localized low-pressure zone, inducing cavitation and achieving nanoscale dispersion. This allows the gel material and diluent to initially fuse in the mixing chamber 302. The second half 304 of the first section is configured as a one-piece spherical tail end connected to a circular baffle structure. The outer wall of the circular baffle fits against the inner wall of the mixing chamber 2. The connection between the first section, front half 301, and second half 304 is axial. A first jet port 303, connected to the mixing chamber 302, pressurizes the initially fused gel and ejects it through multiple right-angle channels. The shearing effect generated by the high-speed jet impact further fuses the raw materials, which then flow into the space between the outer wall of the sphere and the circular baffle in the rear half of the first section 304. The gel is then ejected through a second jet port 305, which is arranged in a circular pattern and tilted towards the axis of the support column, facilitating the fusion of the fluids. The additional section 306 is configured as a rotating body structure with an axial cross-section approximately U-shaped, consisting mainly of a large circular baffle and a small circular baffle. The outer wall of the large circular baffle is fitted to the inner wall of the mixing chamber 2. Multiple... The injection nozzle, pointing towards the small circular baffle, is further configured as a tapered injection nozzle with a gradually decreasing diameter. This allows the raw material to impact the small circular baffle at high speed under compression. The combined effects of cavitation and shearing enhance the fusion effect between the raw materials. Multiple semi-circular protrusions are arranged in an array on the side of the small circular baffle facing the injection nozzle. This creates turbulent shearing after the high-speed jet impacts the baffle, increasing the shearing effect. After passing through multiple additional sections 306, the raw material is gradually homogenized and the dilution process is completed. The diameter of the injection nozzle on each additional section 306 decreases progressively, with the diameter of the first section set to 5 mm and the diameter of the last section set to 2 mm. The diameter of the semi-circular protrusions arranged in the array is set to 0.5 mm, and the spacing is set to 2 mm.

[0019] Adding hollow cylindrical partition sections 307 to the support column allows for adjustment of the distance between each unit section as needed and fills any excess gaps in the support column.

[0020] An online viscosity sensor is installed at the outlet of mixing chamber 2, which can provide real-time feedback on the homogenization status of the raw materials and the dilution effect.

[0021] This solution breaks down the mixer into multiple independent unit sections, each of which is a rotating structure that can be produced through simple machining. Unlike the spiral structure of a static mixer, which requires complex machining processes, this greatly reduces production costs. Furthermore, the multiple independent unit sections can be combined and arranged as needed to achieve customized production processes and reduce maintenance and replacement costs.

[0022] This solution is not only applicable to the dilution process of gel raw materials, but also adaptable to the preliminary homogenization treatment of raw materials that are both medicinal and edible, such as the composite dispersion of Chinese herbal extracts and gel matrix.

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