Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to an antibacterial gel preparation device. Background Technology

[0002] Molybdates are widely used in the construction of functional materials due to their unique redox properties and broad-spectrum antibacterial activity. Among them, calcium molybdate nanoclusters are ideal inorganic components for preparing functional hydrogels due to their high specific surface area, good biocompatibility, and excellent antibacterial properties. The inventors previously published related research results, "Molybdate-Functionalized Polyacrylamide Gel and Its Antibacterial Properties," which elucidated the antibacterial application potential of the gel system (CMG) formed by the composite of calcium molybdate nanoclusters and polyacrylamide (PAM).

[0003] In the actual preparation of CMG, raw materials such as ammonium molybdate and calcium nitrate must be added in batches in a specific order. If the materials are added all at once or too quickly, the local concentration may be too high, leading to the aggregation or phase separation of calcium molybdate nanoclusters and affecting the uniformity of the gel structure. The reaction needs to last for a relatively long time to ensure that the nanoclusters are uniformly embedded in the PAM network. However, as the viscosity of the system increases rapidly, ordinary stirring is difficult to maintain effective mixing, which can easily lead to problems such as uneven mass transfer and incomplete reaction. In addition, CMG is highly viscous during its formation and easily adheres to and accumulates on the side walls of the reaction vessel and the stirring components, which not only reduces the yield and affects heat transfer, but also increases the difficulty of cleaning, which is not conducive to batch reproducibility and large-scale production. Summary of the Invention

[0004] The purpose of this invention is to provide an antibacterial gel preparation device to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides an antibacterial gel preparation device, including a cylinder and a stirring assembly; the top side wall of the cylinder is evenly provided with several feed inlets along the circumference, and the lowest point of the bottom is provided with a discharge outlet; the stirring assembly includes a stirring motor, a stirring shaft, an upward turning blade, a central stirring plate, and a downward turning blade, wherein the upward turning blade and the downward turning blade are respectively fixed above and below the stirring shaft, and the blades bend in opposite directions.

[0006] Furthermore, the stirring assembly also includes a stirring frame, which is fixed on the stirring shaft and has a frame structure similar to the contour of the inner cavity of the cylinder.

[0007] Furthermore, multiple stirring blades are fixed inside the stirring frame, and the edges of the stirring blades are provided with an array of sharp teeth and multiple rows of through holes are opened on the stirring blades.

[0008] Furthermore, a long strip-shaped scraper is provided on the outside of the stirring frame.

[0009] Furthermore, spiral scraper blades are symmetrically arranged on the outer side of the stirring frame.

[0010] Furthermore, a long strip-shaped scraper is provided on the lower outer side of the stirring frame.

[0011] This invention utilizes a multi-level, multi-dimensional mixing system to ensure that high-viscosity materials are thoroughly and rapidly mixed in three-dimensional space. Specifically, multiple independent feed inlets combined with the pre-mixing function of the spiral scraper blades enable precise batch addition and rapid dispersion of raw materials, avoiding agglomeration caused by excessively high local concentrations. The powerful shearing of the central mixing disc and the synergistic effect of the axial circulation formed by the mixing frame and the upper and lower tilting blades ensure uniform reaction. The dual scraping design of the spiral scraper blades and the conical scraper plate prevents the gel product from forming a stable adhesion to the cylinder wall, resulting in high material utilization.

[0017] 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.

[0018] As attached Figure 1-5 As shown, the antibacterial gel preparation device provided by this utility model mainly includes a cylinder 1 and a stirring component 2.

[0019] The cylinder 1 is welded together from an upper cylindrical part and a lower conical part, forming a container with an upper cylindrical part and a lower conical part. Several feed inlets 101 are evenly distributed circumferentially on the top sidewall for adding different raw materials in batches. A discharge outlet 102, equipped with a valve, is located at the lowest point of the conical part.

[0020] A stirring assembly 2 is provided in the center of the cylinder 1. The stirring assembly 2 includes a stirring motor 200, a stirring shaft 201, an upward material-turning blade 202, a stirring frame 203, a central stirring disc 204, a spiral wall-scraping blade 205, and a downward material-turning blade 206. The stirring shaft 201 is connected to the output shaft of the stirring motor 200 via a coupling, and can rotate around its own axis under the drive of the motor. The stirring shaft 201 extends vertically downward and passes through the center of the cylinder 1.

[0021] The stirring system is fixedly installed on the stirring shaft 201 and mainly includes, from top to bottom, an upward material-turning blade 202, a stirring frame 203, a central stirring plate 204, a spiral wall-scraping blade 205, and a downward material-turning blade 206.

[0022] Specifically, the stirring frame 203 is fixed to the stirring shaft 201 by welding. The stirring frame 203 is a frame structure, similar in outline to the inner cavity of the cylinder. Multiple stirring blades 2031 are welded to its inner side (the side facing the stirring shaft). Figure 5 As shown, each stirring blade 2031 has an array of sharp teeth machined on its edge to enhance local shear force. In addition, multiple rows of through holes are regularly opened on the stirring blade 2031. When the material flows through, the through holes can generate local eddies, promoting micro-mixing and gas-liquid exchange.

[0023] like Figure 3 As shown, the lower part of the stirring frame 203 is shaped to match the conical section of the cylinder 1, and is also an inverted triangle. On the outer side of the base of this triangle, a long strip scraper 2032 is installed, with a very small gap between its outer edge and the inner wall of the conical section (usually 1-3 mm), which is used to scrape off and guide the material at the bottom of the cone to prevent sedimentation.

[0024] like Figure 2 , 4 As shown, the central mixing disc 204 is fixed on the mixing shaft 201 and located inside the space enclosed by the mixing frame 203. Multiple circumferentially arranged mixing fins 2041 are welded to both the upper and lower end faces of the central mixing disc 204. Each mixing fin 2041 has multiple small sharp teeth evenly distributed on it. When the mixing shaft 201 rotates at high speed, the central mixing disc 204 and its sharp teeth can generate strong shearing and tearing effects on the material flowing through the inside of the mixing frame, effectively breaking up material agglomerates.

[0025] Two spiral scraper blades 205 are symmetrically welded to the outer wall of the stirring frame 203. For example... Figure 2As shown, the spiral scraper blade 205 starts from the upper part of the stirring frame 203 and extends spirally downward along the inner wall of the cylindrical part of the cylinder 1. It has two functions: first, to scrape off the gel adhering to the cylinder wall during rotation; second, its spiral surface can quickly guide the liquid raw material flowing in from the upper feed port 101 and flowing down the wall to the central area, so as to achieve rapid and uniform premixing.

[0026] like Figure 2 As shown, the upward-turning blade 202 and the downward-turning blade 206 are fixed to the stirring shaft 201 by flanges or welding, respectively, located above and below the inner cavity of the cylinder 1. More specifically, the bending direction of the upward-turning blade 202 is designed to push the material downward during rotation, while the bending direction of the downward-turning blade 206 is opposite, pushing the material upward. The two blades, one above and one below, in opposite directions, form a strong axial circulating flow within the cylinder 1, ensuring thorough mixing of the material in the vertical direction and preventing stratification.

[0027] The working process of this utility model is as follows: Start the stirring motor 200 and run it at low speed. Add raw materials such as ammonium molybdate solution and calcium nitrate solution in sequence according to the process formula through different feed ports 101. The spiral scraper blades 205 immediately entrain the raw materials flowing down the wall into the stirring zone. Adjust the motor to the speed required by the process. The central stirring disc 204 performs core strong shearing on the material; the blades of the stirring frame 203 perform main mixing and dispersion of the material; the upper and lower turning blades create turbulent flow of the material axially; the scraper plate 2032 and the spiral scraper blades 205 continuously clean the wall surface. The multi-component collaboration enables highly viscous materials to reach a highly uniform mixing and reaction state in a short time. After the reaction is complete, open the bottom discharge port 102 valve to discharge the material. During discharge, the stirring can be kept running at low speed to assist in material discharge. After production is completed, cleaning fluid can be injected to thoroughly clean the inside of the device under the action of stirring.

[0028] It should be noted that, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," "fixing," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
