Description

Technical Field

[0001] The utility model relates to the technical field of preparation integrated machines, in particular to an integrated machine for preparing zirconia aerogel. Background Technique

[0002] The alcohol-water heating method is a newly developed method for preparing zirconia aerogel. Inorganic zirconium salts are heated in an alcohol-water mixed solution with a certain volume ratio. During the heating process, the dielectric constant of the alcohol-water mixture decreases, resulting in a significant reduction in the solvation energy of the mixture. The solution finally reaches a supersaturated state and turns into a colloid. At present, in the drying methods for preparing zirconia aerogel, supercritical drying technology is mostly applied at home and abroad. The preparation of aerogel by supercritical drying technology means that after the aging stage is completed, the solvent in the gel is discharged by the sublimation process, leaving nanoscale pores filled with gas, and finally obtaining a lightweight aerogel with a nanoscale pore structure. Since there is no gas-liquid interface and capillary force is ignored, the gel mass will not shrink and collapse during the drying process.

[0003] The existing integrated machines for preparing zirconia aerogel generally require steps such as separately stirring, heating, and mixing the materials. Currently, basically each step is processed by a separate device, and there are many transfer processes in the middle. This causes a large area to be required in the entire production process to place various devices, requires manual participation in various transfers, has low efficiency, is prone to mixing in impurities, and also has a great impact on the quality of the product, which needs to be improved. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an integrated machine for preparing zirconia aerogel to solve the technical problem that each step is processed by a separate device.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An integrated machine for preparing zirconia aerogel, including a base, a constant temperature chamber is fixedly connected to the top of the base, an aging and replacement integrated mechanism is arranged inside the constant temperature chamber, a raw material preparation chamber is connected to the top of the constant temperature chamber through a bracket, and an alcohol-water reaction chamber is connected to the bottom of the raw material preparation chamber through a valve;

[0007] A spray nozzle is fixedly connected to the top of the aging chamber, and a liquid inlet pump is connected to the top end of the spray nozzle.

[0008] By adopting the above technical solutions, a fully automated preparation process from material mixing, reaction, aging, washing to drying is achieved, significantly improving production efficiency and reducing the need for manual intervention, thereby reducing the risk of impurity mixing and enhancing product quality.

[0012] By adopting the above technical solutions, the liquid outlets provided on both sides of the top of the gel mold are arranged opposite to the openings on both sides of the aging chamber, enabling the washing liquid to flow out smoothly through the liquid outlets and openings after being sprayed onto the gel mold and being collected by the liquid receiving tank, thereby realizing the effective recycling of the washing liquid.

[0013] Furthermore, an electric push rod is fixedly connected to the inner wall of one side of the constant temperature chamber, and a push plate is fixedly connected to one end of the electric push rod.

[0014] By adopting the above technical solutions, the electric push rod fixedly connected to the inner wall of one side of the constant temperature chamber and the push plate fixedly connected to one end thereof constitute an automated pushing mechanism. After the gel mold completes the aging and replacement process in the aging chamber, the electric push rod can drive the push plate to push the gel mold out of the outlet of the constant temperature chamber for subsequent drying treatment, not only improving the automation degree of the equipment but also reducing the complexity of manual operation, thereby improving production efficiency.

[0015] Furthermore, the bottom of the alcohol-water reaction chamber is connected to the feed valve, and an outlet is provided on the inner wall of the other side of the constant temperature chamber.

[0016] By adopting the above technical solutions, the bottom of the alcohol-water reaction chamber is connected to the feed valve, enabling the reaction product in the alcohol-water reaction chamber to smoothly enter the aging chamber through the feed valve for subsequent aging treatment, ensuring the continuity and high efficiency of the production process.

[0017] Furthermore, a supercritical drying chamber is provided on one side of the constant temperature chamber, and a sealed chamber door is rotatably connected to the front side of the supercritical drying chamber.

[0018] By adopting the above technical solution, the supercritical drying chamber provided on one side of the constant temperature chamber provides a dedicated drying environment for the gel mold.

[0032] Next, the embodiments of the present invention will be described according to the overall structure of the present invention. Embodiment 1:

[0035] A nozzle 305 is fixedly connected to the top of the aging chamber 302. The top end of the nozzle 305 is connected to a liquid inlet pump 306. The constant temperature chamber 2 in the equipment provides a stable working environment for the integrated aging and replacement mechanism 3, reduces the number of chambers, ensures the temperature control accuracy during the aging process, and further improves the stability and consistency of the product.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The bottom of the alcohol-water reaction chamber 6 is connected to the feed valve 301. An outlet 311 is opened on the inner wall of the other side of the constant temperature chamber 2. The outlet 311 opened on the inner wall of the other side of the constant temperature chamber 2 provides a convenient passage for the gel mold 304 after aging treatment, enabling it to be smoothly pushed out of the constant temperature chamber 2 and then undergoing subsequent drying treatment.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A supercritical drying chamber 7 is arranged on one side of the constant temperature chamber 2. A sealed chamber door 8 is rotatably connected to the front side of the supercritical drying chamber 7.

[0038] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A motor 9 is arranged on the top of the raw material preparation chamber 4. A stirring blade 10 is fixedly connected to the output end of the motor 9. The automated stirring system also reduces the complexity and labor intensity of manual operation and improves the overall production efficiency. Embodiment 2:

[0039] Refer to Figure 3 and Figure 4 An electric push rod 309 is fixedly connected to the inner wall of one side of the constant temperature chamber 2. One end of the electric push rod 309 is fixedly connected to a push plate 310. Due to the precise control of the electric push rod 309 and the push plate 310, the stability and accuracy of the gel mold 304 during the pushing process can be ensured, avoiding damage or quality problems caused by improper manual operation.

[0040] Refer toFigure 3 and Figure 4 On both sides of the top of the gel mold 304, liquid outlets 312 are provided. The liquid outlets 312 are arranged opposite to the openings 307, which also ensures that the gel mold 304 can fully contact the washing liquid during the washing process, improving the washing effect and further ensuring the product quality.

[0042] The implementation principle of the present utility model is as follows: First, put the materials into the raw material preparation bin 4, then start the motor 9. The motor 9 drives the stirring blades 10 to rotate, thereby realizing the mixing of the materials. After that, the mixed materials enter the inside of the alcohol-water reaction chamber 6 through the valve 5 for reaction. The materials after the reaction enter the inside of the gel mold 304 at the bottom of the aging chamber 302 through the feed valve 301, and then the heat preservation and aging operation is carried out. When the heat preservation and aging operation is completed, the liquid inlet pump 306 sprays anhydrous ethanol through the nozzle 305 to wash the gel materials. When the washing is completed, the lifting rod 313 drives the lifting platform 303 to rise. At this time, the anhydrous ethanol flows out from the liquid outlet 312 through the opening 307 into the inside of the liquid receiving tank 308, and then the circulation is realized through the liquid inlet pump 306;

[0043] After that, when the gel mold 304 rises to the position of the opening 307, the electric push rod 309 drives the push plate 310 to push the gel mold 304 out from the outlet 311 on the constant temperature chamber 2 and is pushed into the supercritical drying chamber 7. Manually close the sealed chamber door 8 to dry the gel. Finally, open the sealed chamber door 8, take out the gel, and complete the preparation.
