Description

Technical Field

[0001] This utility model relates to the field of aerogel preparation technology, and in particular to a liquid preparation device for preparing fiber aerogel. Background Technology

[0002] Aerogels are the lightest known solid materials in the world. Due to their extremely low thermal conductivity, durability, high temperature resistance, and explosion-proof properties, they have broad application prospects in aerospace, defense, green building, new energy, environmental governance, and solar thermal utilization. Waste textiles, characterized by large quantities, low prices, and difficulty in degradation, can be transformed into aerogel materials with excellent properties through specific processing techniques. In the preparation of fiber aerogels, polyvinyl alcohol (PVA) powder needs to be mixed with water to prepare a PVA solution.

[0003] Chinese utility model patent CN216799616U discloses an aerogel insulation coating mixing and preparation device. The device uses a flipping drive component to drive the tank to flip. An upper shaft head is set on the end cap, and a lower shaft head is set at the bottom of the tank. The spline shaft connected to the stirring motor can drive the upper and lower shaft heads to rotate. Even after the tank is flipped, the stirring shaft can still drive the stirring rod to rotate, thus achieving the stirring function. With the combination of flipping and stirring, the coating is stirred more evenly and the mixing effect is better.

[0004] Although the device achieves the effect of mixing raw materials by flipping the tank, in actual use, it still uses a stirring rod that rotates in only one direction for mixing. For mixing high-viscosity PVA solutions, although basic mixing can be achieved, problems such as uneven mixing and dead zones often exist. This not only directly affects the uniformity of the solution and the performance of the subsequent fiber aerogel, but also reduces the efficiency of solution preparation. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a liquid preparation device for the preparation of fiber aerogels.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a liquid preparation device for the preparation of fiber aerogel, comprising: a liquid preparation tank, a top cover installed on the top of the liquid preparation tank, and a homogenizing liquid preparation mechanism installed on the top cover;

[0007] The homogenization and dispensing mechanism includes: a servo motor installed on the top of the top cover, a transmission rod fixed to the output end of the servo motor, and a rotating rod rotatably connected to the side of the transmission rod; several stirring blades are installed on the sides of the transmission rod and the rotating rod near the bottom.

[0008] A transmission frame is fixed to the bottom of the top cover. A driving bevel gear is fixed to the side of the transmission rod inside the transmission frame. A driven bevel gear is fixed to the side of the rotating rod inside the transmission frame. Several transmission bevel gears are rotatably connected to the inner side of the transmission frame. The sides of the transmission bevel gears mesh with the sides of the driving bevel gear and the driven bevel gear, respectively.

[0009] In a preferred embodiment of this utility model, the sides of both the transmission rod and the rotating rod are rotatably connected to the inner side of the transmission frame; the stirring blades on the transmission rod and the stirring blades on the rotating rod are both inclined and in opposite directions; the transmission bevel gear is perpendicular to the driving bevel gear and the driven bevel gear.

[0010] In a preferred embodiment of this utility model, a heating layer is provided on the inner side of the liquid preparation tank, and the heating layer achieves heating through thermal radiation or thermal conduction.

[0012] In a preferred embodiment of this utility model, the bottom of the liquid preparation tank is arc-shaped and the top is cylindrical.

[0013] In a preferred embodiment of this invention, a pressure gauge for monitoring the internal pressure of the liquid preparation tank is installed on the side of the liquid preparation tank.

[0014] In a preferred embodiment of the present invention, a feed pipe and a liquid inlet pipe are fixed to the top of the top cover, and the interiors of the feed pipe and the liquid inlet pipe extend to the lower surface of the top cover.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a liquid preparation device for the preparation of fiber aerogel. By installing a homogenizing liquid preparation mechanism on the top cover, after adding PVA powder and water into the liquid preparation tank, the servo motor, transmission rod, active bevel gear, transmission bevel gear, driven bevel gear, rotating rod and stirring blades cooperate to enable several stirring blades on the transmission rod and rotating rod to rotate synchronously in opposite directions. The stirring blades in the two directions can complement each other, reduce the stirring dead angle, make PVA powder disperse and dissolve in water more quickly, and generate interactive shear force, which helps to break the PVA powder agglomerates, so that it can contact and mix more fully with water, thereby improving the uniformity of the solution and helping to improve the performance and quality of the final product.

[0020] (2) In this utility model, by setting a heating layer on the inner side of the liquid preparation tank, heat can be transferred to the solution in the liquid preparation tank by means of thermal radiation or thermal conduction, thereby increasing the liquid preparation temperature of the solution to a certain extent, thereby promoting the reaction rate of the raw materials in the liquid preparation and improving the fluidity of the solution.

[0021] (3) In this utility model, by setting the bottom of the liquid preparation tank to be arc-shaped and the top to be cylindrical, the arc-shaped bottom of the liquid preparation tank helps the solution to form a more uniform flow during the stirring process and reduce dead corners, while the cylindrical top facilitates the installation and connection of other components.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a liquid preparation device for preparing fiber aerogel includes: a liquid preparation tank 1, a top cover 11 installed on the top of the liquid preparation tank 1, and a homogenizing liquid preparation mechanism installed on the top cover 11; the homogenizing liquid preparation mechanism includes: a servo motor 2 installed on the top of the top cover 11, a transmission rod 21 fixed to the output end of the servo motor 2, and a rotating rod 22 rotatably connected to the side of the transmission rod 21; several stirring blades 23 are installed on the sides of the transmission rod 21 and the rotating rod 22 near the bottom; a transmission frame 24 is fixed to the bottom of the top cover 11, a driving bevel gear 25 is fixed to the side of the transmission rod 21 inside the transmission frame 24, a driven bevel gear 26 is fixed to the side of the rotating rod 22 inside the transmission frame 24, and several transmission bevel gears 27 are rotatably connected to the inner side of the transmission frame 24, the sides of the transmission bevel gears 27 meshing with the sides of the driving bevel gear 25 and the driven bevel gear 26 respectively.

[0029] It should be noted that the sides of both the transmission rod 21 and the rotating rod 22 are rotatably connected to the inner side of the transmission frame 24; the stirring blades 23 on the transmission rod 21 and the rotating rod 22 are both inclined, and the inclination directions are opposite; the transmission bevel gear 27 is perpendicular to the driving bevel gear 25 and the driven bevel gear 26; after PVA powder and water are added into the liquid preparation tank 1, the transmission rod 21 is driven to rotate by the servo motor 2, the driving bevel gear 25 on the transmission rod 21 drives the transmission bevel gear 27 meshing with it to rotate, and then drives the driven bevel gear 26 on the rotating rod 22 to rotate. The rotating rod 22 is rotatably connected to the side of the transmission rod 21, thereby enabling the transmission rod 21 and the rotating rod 22 to rotate synchronously but in opposite directions. This allows several stirring blades 23 on the transmission rod 21 and the rotating rod 22 to rotate synchronously in opposite directions. The stirring blades 23 in the two directions can complement each other, reducing the stirring dead angle, allowing the PVA powder to disperse and dissolve in water more quickly, and generating interactive shear forces, which helps to break up PVA powder agglomerates, allowing it to contact and mix more fully with water, thereby improving the uniformity of the solution and helping to improve the performance and quality of the final product.

[0030] In some embodiments, a heating layer 3 is provided on the inner side of the liquid preparation tank 1. The heating layer 3 achieves heating through thermal radiation or thermal conduction. By providing the heating layer 3, heat can be transferred to the solution in the liquid preparation tank 1 through thermal radiation or thermal conduction, thereby increasing the liquid preparation temperature of the solution to a certain extent, which can promote the reaction rate of the raw materials in the liquid preparation and improve the fluidity of the solution.

[0031] In some embodiments, a thermometer 4 is installed on the side of the mixing tank 1 to monitor the internal temperature of the mixing tank 1; the thermometer 4 is used to monitor the internal temperature of the mixing tank 1 in real time to ensure that the solution is kept within the required temperature range during the preparation process.

[0032] In some embodiments, the bottom of the mixing tank 1 is arc-shaped and the top is cylindrical; the arc-shaped bottom of the mixing tank 1 helps the solution to form a more uniform flow during stirring and reduce dead corners, while the cylindrical top facilitates the installation and connection of other components.

[0033] In some embodiments, a pressure gauge 5 is installed on the side of the mixing tank 1 to monitor the internal pressure value of the mixing tank 1; the pressure gauge 5 is used to monitor the internal pressure value of the mixing tank 1 to ensure that the pressure is within a safe range during the preparation process.

[0034] In some embodiments, a feed pipe 6 and a liquid inlet pipe 7 are fixed to the top of the top cover 11, and the interiors of the feed pipe 6 and the liquid inlet pipe 7 extend to the lower surface of the top cover 11; the feed pipe 6 and the liquid inlet pipe 7 facilitate the addition of raw materials such as PVA powder and water into the liquid mixing tank 1 respectively.

[0035] In some embodiments, a discharge cylinder 8 is fixed to the bottom of the mixing tank 1, the interior of the discharge cylinder 8 extends into the interior of the mixing tank 1, and a valve is installed on the side of the discharge cylinder 8; the valve is used to control the opening and closing of the discharge cylinder 8, and the discharge cylinder 8 is used to discharge the prepared solution from the mixing tank 1.

[0036] In some embodiments, the side of the mixing tank 1 is provided with an observation window 9 for observing the internal condition of the mixing tank 1; the observation window 9 allows the operator to observe the internal condition of the mixing tank 1 without opening it, which facilitates timely detection and problem solving and ensures the smooth progress of the preparation process.

[0037] In some embodiments, a support frame 10 is provided at the bottom of the liquid preparation tank 1 to provide support; by supporting the liquid preparation tank 1 with the support frame 10, the weight of the liquid preparation tank 1 and its internal solution can be effectively distributed and borne, ensuring its stability and safety during the preparation process.

[0038] In use, PVA powder and water are added to the mixing tank 1 through the feed pipe 6 and liquid inlet pipe 7 on the top of the top cover 11, respectively. The servo motor 2 installed on the top cover 11 is then started, driving the transmission rod 21 to rotate. The driving bevel gear 25 on the transmission rod 21 drives the meshing transmission bevel gear 27 to rotate, which in turn drives the driven bevel gear 26 on the rotating rod 22 to rotate. Since the rotating rod 22 is rotatably connected to the side of the transmission rod 21, the transmission rod 21 and the rotating rod 22 can rotate synchronously but in opposite directions. This causes several stirring blades 23 on the transmission rod 21 and the rotating rod 22 to rotate synchronously in opposite directions. The stirring blades 23 in the two directions complement each other, reducing dead zones and allowing the PVA powder to disperse and dissolve in the water more quickly. Simultaneously, the interacting shear force helps break up PVA powder agglomerates and improves the uniformity of the solution. During the stirring process, the heating layer 3 inside the mixing tank 1 transfers heat to the solution through thermal radiation or conduction, increasing the mixing temperature, promoting the reaction rate of the raw materials, and improving the fluidity of the solution. Meanwhile, the temperature gauge 4 and pressure gauge 5 on the side of the mixing tank 1 monitor the temperature and pressure of the solution in real time, ensuring that the preparation process is carried out within the required temperature and pressure range. After preparation, the solution is discharged through the discharge cylinder 8 and valve fixed at the bottom of the mixing tank 1. In addition, the observation window 9 on the side of the mixing tank 1 allows the operator to observe its internal condition without opening the tank, enabling timely detection and troubleshooting. The entire device is supported by the support frame 10 at the bottom of the mixing tank 1, ensuring stability and safety during the preparation process.
