Abstract
Description
Technical Field
[0001] This utility model relates to the field of material preparation and processing technology, and in particular to a uniform mixing device for processing sol-gel type resins. Background Technology
[0002] The sol-gel method is a wet chemical synthesis approach widely used in materials science to prepare various bulk materials, thin film materials, fiber materials, and composite materials. This method uses organometallic compounds, inorganic metals, or mixtures of both as precursors, which are dissolved in a solvent to form a sol. Then, through chemical reactions such as hydrolysis and condensation, a gel is formed. Finally, the desired material is obtained through drying and sintering. The sol-gel mixing apparatus plays a crucial role in this process.
[0003] However, traditional mixing devices used for sol-gel resin processing are prone to uneven material dispersion during feeding, resulting in localized accumulation in the reaction vessel, leading to poor mixing and affecting product quality.
[0004] For example, in the processing of sol-gel type resins, there are many types of materials (such as powder and liquid). The order of adding materials may be unreasonable. For example, if a high-viscosity resin liquid or filler is added first and then a wetting agent is added, the abrasive particles may be surrounded by the high-viscosity material, which may easily form small clumps or binder balls. They may not be fully wetted by the wetting agent, resulting in uneven material dispersion and thus affecting the mixing effect. Utility Model Content
[0005] This utility model discloses a uniform mixing device for the processing of sol-gel type resins, which aims to solve the technical problem that uneven material dispersion during feeding can easily lead to local accumulation in the reaction vessel, resulting in poor mixing effect and affecting product quality.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A homogeneous mixing apparatus for processing sol-gel resins includes a base frame, a mixing tank, and a sealing cap hinged to the top outer wall of the mixing tank, and further includes:
[0008] Stirring mechanism: The stirring mechanism is set on the bottom inner wall of the stirring tank. A support shaft is set on the bottom inner wall of the stirring tank through a bearing. The outer circumference of the support shaft is provided with auger blades, a dispersing plate and several sets of dispersing rods distributed at equal distances. A motor is connected to one end of the support shaft.
[0009] Auxiliary mechanism: The auxiliary mechanism is disposed on the inner circumference of the mixing tank.
[0010] In this case, the material is initially dispersed by a motor-driven dispersing rod. This step helps to break up clumps and agglomerates in the material, laying the foundation for the subsequent mixing process. The material is further dispersed by a dispersing plate. This design allows the material to be more evenly distributed in the mixing tank, avoiding the problems of local accumulation and uneven mixing. The mixing mechanism, through the synergistic action of the auger blades, dispersing plate, and dispersing rod, mixes and stirs the material in the mixing tank in all directions. This mixing method not only improves the mixing efficiency but also ensures the stability and consistency of the mixing quality.
[0011] In a preferred embodiment, the dispersion plate has a conical structure, and a number of equally spaced perforated holes are provided on the top outer wall of the dispersion plate. The number of dispersion rods in each group is two, and each group of dispersion rods is arranged in a figure-eight shape on the circumferential outer wall of the support shaft.
[0012] In particular, the dispersing plate adopts a conical structure design, which not only increases the surface area of the dispersing plate, but also allows the material to be subjected to a more uniform dispersing force when flowing through the dispersing plate. The conical structure also ensures that the material can flow more smoothly from the top to the bottom of the dispersing plate, avoiding the accumulation and blockage of the material on the dispersing plate. Several equally spaced perforations are opened on the top outer wall of the dispersing plate, which not only provides additional flow channels for the material, but also allows the material to be subjected to shear force and dispersing force when flowing through the perforations, thereby achieving a more uniform dispersion effect. The figure-eight structure of the dispersing rod can generate greater stirring force and shear force when rotating, which helps to mix and disperse the material more quickly and thoroughly.
[0013] In a preferred embodiment, the auxiliary mechanism includes a spiral groove, which is formed inside the wall of the mixing tank. The spiral groove has several equidistant air holes on its inner circumferential wall, and an air supply pipe is connected to one end of the spiral groove.
[0014] Specifically, the auxiliary mechanism has spiral grooves inside the mixing tank wall and several equidistant air holes on its inner wall. During use, high-pressure inert gas is stably transmitted into the mixing tank through the air supply pipe. When the high-pressure inert gas is injected into the material through the air holes on the spiral groove, it will produce a strong shearing and dispersing effect on the material, thereby further dispersing and mixing the material, improving the mixing uniformity, ensuring the consistency and stability of product quality, optimizing production efficiency, and shortening the production cycle.
[0015] As described above, a uniform mixing device for processing sol-gel resins includes a base frame, a mixing tank, and a sealing cover hinged to the top outer wall of the mixing tank. It further includes: a stirring mechanism disposed on the bottom inner wall of the mixing tank, with a support shaft mounted on the bottom inner wall of the mixing tank via bearings; auger blades, a dispersing plate, and several sets of equidistant dispersing rods disposed on the outer circumference of the support shaft; and a motor connected to one end of the support shaft; and an auxiliary mechanism disposed on the inner circumference of the mixing tank. The uniform mixing device for processing sol-gel resins provided by this invention has the technical effect of improving the uniformity of material dispersion. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0023] The present invention discloses a uniform mixing device for processing sol-gel type resins, which is mainly used in scenarios where uneven material dispersion is easily encountered during feeding, resulting in local accumulation in the reaction vessel, leading to poor mixing effect and affecting product quality.
[0024] Reference Figure 1 , Figure 3 and Figure 4 A uniform mixing device for processing sol-gel type resins includes a base frame 1, a mixing tank 2, and a sealing cover 3 hinged to the top outer wall of the mixing tank 2. It also includes: a mixing mechanism: the mixing mechanism is disposed on the bottom inner wall of the mixing tank 2, a support shaft 7 is disposed on the bottom inner wall of the mixing tank 2 via bearings, and a auger blade 12, a dispersing plate 8, and several sets of equally spaced dispersing rods 9 are disposed on the circumferential outer wall of the support shaft 7; a motor 15 is externally connected to one end of the support shaft 7; and an auxiliary mechanism: the auxiliary mechanism is disposed on the circumferential inner wall of the mixing tank 2.
[0025] A heating module 13 is installed inside the mixing tank 2, a pressure relief valve 4 and four first valves 5 are installed on the top outer wall of the sealing cover 3, and a second valve 14 is installed on the bottom inner wall of the mixing tank 2.
[0026] The heating module 13 not only improves the processing efficiency of sol-gel resin, but also ensures the stability and consistency of product quality. By precisely controlling the temperature of the heating module 13, we can optimize the resin curing process and obtain products with better performance.
[0027] Among them, the four first valves 5 are used for feeding, the second valve 14 is used for discharging, and the design of the pressure relief valve 4 ensures that the device can safely release excess pressure in a high-pressure environment, preventing safety accidents caused by excessive pressure. The setting of the four first valves 5 allows us to conveniently add multiple raw materials at the same time, improving production efficiency.
[0028] In a specific implementation, the material is initially dispersed by the dispersing rod 9 driven by the motor 15. This step helps to break up clumps and agglomerates in the material, laying the foundation for the subsequent mixing process. The material is further dispersed by the dispersing plate 8. This design allows the material to be more evenly distributed in the mixing tank 2, avoiding the problems of local accumulation and uneven mixing. The mixing mechanism, through the synergistic action of the auger blades 12, the dispersing plate 8 and the dispersing rod 9, mixes and stirs the material in the mixing tank 2 in all directions. This mixing method not only improves the mixing efficiency, but also ensures the stability and consistency of the mixing quality.
[0029] Reference Figure 3 and Figure 4 In a preferred embodiment, the dispersing plate 8 has a conical structure, and a number of equally spaced perforated holes 16 are provided on the top outer wall of the dispersing plate 8. There are two dispersing rods 9 in each group, and each group of dispersing rods 9 is arranged in a figure-eight shape on the circumferential outer wall of the support shaft 7.
[0030] In particular, the dispersing plate 8 adopts a conical structure design, which not only increases the surface area of the dispersing plate 8, but also allows the material to be subjected to a more uniform dispersing force when flowing through the dispersing plate 8. The conical structure also ensures that the material can flow more smoothly from the top to the bottom of the dispersing plate 8, avoiding the accumulation and blockage of the material on the dispersing plate 8. Several equally spaced perforations 16 are opened on the top outer wall of the dispersing plate 8, which not only provides additional flow channels for the material, but also allows the material to be subjected to shear force and dispersing force when flowing through the perforations 16, thereby achieving a more uniform dispersion effect. The figure-eight shaped dispersing rod 9 can generate greater stirring force and shear force when rotating, which helps to mix and disperse the material more quickly and thoroughly.
[0031] Reference Figure 4 In a preferred embodiment, one end of the support shaft 7 has a conical structure. Due to the guiding effect of the conical surface, the material can flow more smoothly to the bottom of the mixing tank 2. By maintaining a gap of 0.5-2mm with the inner wall of the mixing tank 2, the material is fully mixed by the auger blades 12, avoiding the problems of local accumulation and uneven mixing.
[0032] Reference Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the auxiliary mechanism includes a spiral groove 11, which is formed inside the wall of the mixing tank 2. The spiral groove 11 has a plurality of equally spaced air holes 10 on its inner circumferential wall, and an air supply pipe 6 is connected to one end of the spiral groove 11.
[0033] Specifically, the auxiliary mechanism has a spiral groove 11 inside the wall of the mixing tank 2, and several equidistant air holes 10 on its inner wall. In use, high-pressure inert gas is stably transmitted into the mixing tank 2 through the air supply pipe 6. When the high-pressure inert gas is injected into the material through the air holes 10 on the spiral groove 11, it will produce a strong shearing and dispersing effect on the material, thereby further dispersing and mixing the material, improving the mixing uniformity, ensuring the consistency and stability of product quality, optimizing production efficiency, and shortening the production cycle.
[0034] Reference Figure 3 In a preferred embodiment, the starting edge of the spiral groove 11 is parallel to the bottom edge of the dispersion plate 8.
[0035] In particular, this positioning ensures that the vents 10 are tightly surrounding the dispersion plate 8. When high-pressure inert gas is injected through the vents 10, it can directly generate a strong shearing and dispersing effect on the material on the dispersion plate 8. This alignment not only improves the dispersion effect of the material, but also further enhances the uniformity of the mixture.
[0036] Working Principle: During operation, the operator first starts the equipment. The motor 15 drives the support shaft 7 to rotate at low speed, which in turn drives the auger blades 12, dispersing plate 8, and dispersing rods 9, all mounted on the outer circumference of the support shaft 7, to work together. Different materials are then added to the mixing tank 2 through four first valves 5. The dispersing rods 9 initially disperse and mix the materials. Subsequently, the materials flow through the conical dispersing plate 8. Guided by the dispersing plate 8, the materials experience a more uniform dispersing force and are further subjected to shearing and dispersing forces through the perforations 16 on the top outer wall of the dispersing plate 8, achieving even more uniform mixing. To achieve the desired dispersion effect, the heating module 13 starts working to maintain a constant temperature for the materials in the mixing tank 2, ensuring that the sol-gel resin is mixed and reacted at a suitable temperature. During the feeding process, in order to further improve the mixing uniformity, high-pressure inert gas is stably transmitted into the mixing tank 2 through the gas supply pipe 6. The gas is sprayed into the falling materials through the spiral groove 11 opened inside the mixing tank 2 and the air holes 10 on the inner wall to further disperse them. Finally, when the materials are mixed evenly, the second valve 14 is opened to discharge the mixed sol-gel resin from the mixing tank 2 for subsequent processing and treatment.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
